Modern society is a colorful era, commodity economy prosperity, people's living standards gradually improve, all kinds of commodity packaging and fashion linked, it can be said that all goods can not be separated from the packaging and packaging machinery. Now most of the packaging machinery in China are low production efficiency, high energy consumption, poor reliability and stability, product form lag behind and so on, which is also the gap between domestic packaging machine equipment and international technology. Due to the rapid development of the packaging industry, the country has also increased the supervision of the packaging machinery industry, packaging machine technology has higher requirements, prompting some production of packaging machinery and equipment enterprises have to increase the investment in packaging machinery and technological innovation. At present, domestic packaging machine manufacturers should take advantage of new technology or other more advanced technology into the packaging machinery manufacturing, grasp the right time, accelerate the development, to the packaging machinery new direction. Create a new type of packaging machinery equipment, leading packaging machinery towards integration, intelligent, efficient direction, will be our packaging machinery industry to a new height, worthy of attention in the industry.
China's food and packaging machinery industry has been in the industry for 20 years, compared to the food industry is still a new industry. These 20 years are a period of rapid technological development in the world. New technologies are constantly being applied in the industry. The domestic industry has a weak foundation and insufficient technical and scientific research strength. Its development is relatively lagging behind, dragging the food and packaging industry to some extent. The hind legs. In recent years, China's food industry has developed rapidly, and its development rate has reached 18% to 21%. Among them, the beverage industry such as dairy products and juices is developing rapidly. In recent years, imported equipment is not domestically manufactured or manufacturing levels are very different. From the imported products, we can see that our gap lies. Although the overall development is faster, the food and packaging industry is growing faster. For the food industry to catch up with the world's advanced level, in order to make packaging countries move toward packaging powers, provide advanced technology and equipment, so that imported equipment can only play a role in the domestic market. This requires that the annual development rate of domestic food and packaging machinery exceeds 18%, and the output rate of new products reaches 25%.
The development of packaging and food machinery in the world is aimed at the requirements of major customers and drives the development of related machinery. The requirements of major customers are mainly reflected in the following aspects: First, adaptable product changes. Packaging machinery requires a high degree of flexibility and flexibility, and the production line allows the size of the package to vary within a certain size range. Because the life cycle of the product is much shorter than the service life of the equipment, changing the product and packaging will not replace the expensive packaging production line; second, the higher the production efficiency requirements, the better. This can reduce the cost of the product and meet the delivery date. The high-speed packaging machine needs to be connected with the previous process, and does not need to carry out the process, including the control connection. The entire production line is arranged in reverse order according to the production and packaging process, and the sequence is stopped. For example, the cold filling production line automatically goes from the plastic raw materials to the beverage filling, and the large packaging yards are automatically carried out in the closed workshop; the third is that the common faults of the equipment are quickly eliminated. The solution is pre-entered into the computer. When the device has a common fault, it can be diagnosed by itself, remote diagnosis and troubleshooting can be carried out. Fourth, environmental pollution can be minimized. Reducing noise, dust pollution, and minimizing waste is especially important in food processing. In the processing of food raw materials, not only the main products, such as corn processing products in addition to corn starch, corn oil, salad oil, margarine, glucose, corn protein and feed, as well as sewage treatment and other production processes, are automated. No waste, no pollution, the value of other products has greatly exceeded the value of corn starch; fifth is required to have automatic identification.On the one hand, it can automatically identify the thickness, hardness, rebound force, etc. of the packaging material, and feedback to the robot through the computer to adjust the range of motion to ensure no rebound. On the other hand, a variety of different products, such as chocolates or snacks of various shapes, are placed in the same box, and the arrangement is regular. The products delivered by the production line are disordered. It can be scanned by the probe to determine the position of materials with different shapes, and then fed back to different robots. It will accurately place the items in the tray according to the exact position and direction, fast and accurate. Manual manipulation of vision and finger fatigue.
Domestic companies have made great progress in filling equipment, packaging equipment, and packaging materials production equipment. However, there are more than 1,300 kinds of packaging machinery in China, lacking high-tech, high-precision, high-quality accessory products, low product performance, poor stability and reliability, and still need high-end technology to help upgrade packa
At present, China's fast-moving consumer goods industry is developing rapidly, which is a greater opportunity for the packaging industry. Therefore, it is necessary to fully understand the advantages and disadvantages in the development of China's packaging machinery industry and accurately formulate the next development plan. Nowadays, the packaging market needs to improve the production efficiency of mechanical equipment. The continuous production equipment replaces the intermittent production equipment, the specialized production equipment replaces the general production equipment, and the humanized production equipment replaces the small and medium-sized production equipment. Continuous production, specialized operation, automatic adjustment, and large-scale operation of the production line can significantly improve production efficiency and economic benefits. Generally speaking, the development of packaging machinery in China has not only expanded in terms of equipment scale, but is also accelerating the integration of opto-mechatronics and automation. With the continuous development and advancement of technology, future microelectronics, computers, industrial robots, image sensing technology and new materials will be more and more widely used in packaging machinery.
In the past 20 years, the food processing industry, which has a large number of transformed agricultural products, has developed at an alarming rate and has become one of the fastest growing industries in China's national economy. From the early 1980s to the present, the national food industry has grown at an average annual rate. 13% to 14%. The rapid development of the agricultural product processing industry provides a broad space for the development of the food machinery industry. Due to the wide variety of processing objects, processing properties and process conditions in the food industry, the food machinery used must meet the processing requirements of the final product, and has specific requirements for the product quality, safety and hygiene, and convenient nutrition. Invited experts from China Food Machinery and Equipment Network believe that food machinery has the market applicability requirements in addition to the commonality of general mechanical products.
The equipment used by food processing enterprises in China is mainly divided into three sizes: large, medium and small. According to the national industrial policy and industry development requirements, we will focus on the development of medium and large-scale production scales, while small-scale production enterprises should be self-destructive according to the laws of the market economy. However, the equipment produced by China's food machinery manufacturing industry is mainly equipped with small and medium-sized enterprises, and large-scale complete sets of equipment are required to be imported. The technical level of food machinery is an important indicator for measuring the technical equipment capabilities of the food industry. The current technical grades of China's food machinery are mainly divided into three levels: high, medium and low. According to the national industrial policy and industry development requirements, we will focus on developing medium and high-grade technology levels, while the low-level technology level should not be supported by key factors, and will gradually be eliminated as the industry develops. However, the equipment level of China's food machinery manufacturing industry is mainly medium and low-grade, and the high-tech products currently used rely heavily on foreign companies. Due to the wide variety of agricultural products, many food processing products are seasonal, such as potato processing, sweet potato processing, cassava processing, fruit processing, vegetable processing, and sugar processing. For food machinery that requires seasonal production, the processing technical requirements of different geographical conditions, different seasonal climates and different seasons must be fully considered.
Mechanical safety is based on the needs of human beings. Under various conditions of using the whole process of machinery, the state of existence and guarantee conditions that protect people's mind and body from external factors are achieved. Mechanical safety refers to the ability of a machine to perform a predetermined function under predetermined conditions of use, or to cause damage or health hazard when transported, installed, adjusted, and the like. There are mechanical safety, production safety and food safety hazards in general food processing. Mechanical safety is the result of no harm to the machine, reducing the mechanical risk to a low level. Production safety is sufficient for safe production, industrial hygiene, and the safety and health of employees in production. The safety behavior of people and the material conditions required for safe production are regulated in terms of management, production technology and equipment use. Food safety mainly includes food hygiene, food quality, food nutrition and other related aspects.
Hygiene and application are the requirements of the mechanical structure of the food machinery design and manufacturing process, including the structural materials, surface structure, cleanability, durability, and inspectability of the product contact surface and non-product contact surface. For the mechanical structure of food machinery, key control points for sanitary hazards should be identified and measures taken to ensure the sanitary requirements of the mechanical struc
In industrialized food processing, most of them are not produced in a single machine, but in a production line. Therefore, the suitability of the package is an important part of ensuring continuous operation, balanced production, processing performance and product quality. The complete set of principles is to achieve a reasonable economic scale, meet the technical requirements of the process and a reasonable match between equipment and equipment, so that the production line is normal. Operation, safety and health, energy saving and easy maintenance, ensuring the advanced, rational and reliable machine.
In recent years, packaging machinery equipment, production line manufacturing groups and multinational companies in many countries in the world have invested huge amounts of money and organized professionals to carry out research and development, and strive to accelerate the process of mechanical and electrical integration of packaging machinery and equipment. The focus of its development research can be summarized as follows: First, the development of a variety of resin molding machines, a variety of resin extruders, a variety of film blowing machines, and a variety of resin flow multi-function models. Develop production lines that reduce self-weight, reduce space, compact structure, easy installation and replacement, less maintenance (less) fault operation, and online quick repair and non-stop repair; second, development of energy saving (water, electricity, oil, steam, etc.) The types of resources (raw materials, auxiliary materials, etc.) consumption indicators, as well as the types of waste recycling; third, the development of a variety of substrate bags packaging, filling, filling and packaging of multi-function models, can be paper, plastic Multi-functional packaging of substrates such as aluminum foil and composite materials; fourthly, the development of multi-shape packaging machines for square, rectangular, circular, elliptical, triangular, pincushion, strip, and odd-shaped packaging The model is for multi-functional packaging; the fifth is to develop and develop models with low energy consumption, large output power, good dynamic stability, low noise and low pollution; and sixth, to develop multi-substrate bag making machines, which can be used for a single layer. Paper bag and plastic film bag, aluminum foil composite bag and paper-plastic composite bag processing and manufacturing of multi-functional models; seven is multi-material packaging machine (filler, filling machine), can be liquid, semi-fluid, sticky, Pulp State and solid particles, granules, powder, flakes, block, strips, and odd-shaped objects are versatile packaging; eight is to develop a multi-range weighing machine, from one kilogram, from A kilogram of kilograms (replacement weighing, hopper), in addition to a progressive improvement of mechanical and electronic sensor scales, the development of interference-free light sensor parts to ensure the weighing accuracy of the material.
With the rapid development of society, the prosperity of the commodity economy and the continuous improvement of people's living standards, commodity packaging has received more and more attention from people, and the related packaging machinery industry has also developed rapidly. China's packaging machinery started late, and after rapid development in recent years, it has become one of the top ten industries in the machinery industry. With the continuous development of science and technology and the continuous improvement of packaging machinery technology, China's packaging machinery industry will usher in Rapid development period.
China's food packaging machinery and equipment are not only on the scale, but also accelerate the integration of opto-mechatronics and automation. Great progress has been made in filling equipment, packaging equipment, and packaging material production equipment. However, China's packaging machinery exports are still less than 5% of the total output value, but the import value is roughly equal to the total output value. This shows that China's demand for packaging machinery is very large. Compared with foreign products, domestic packaging machinery still has a large gap in technology level, which is far from meeting domestic demand.
China's packaging machinery started to develop slowly late, and there was no packaging machinery in the catalogues published by the early countries. Because it has a lot of deficiencies. Mainly reflected in the following aspects: the difference in the size of the enterprise directly leads to a far difference in strength. The different heights of capital, equipment and technical capabilities directly affect the production of enterprise products. Most companies are embarrassed on low-level devices. There are a lot of production in a region, the repetitiveness is large, the price is also competitive, and the profit is weak.
Fast-paced life seeks the convenience of all things, so packaging has become an indispensable part of the economy. Products must go through the packaging when they enter the market. In this form, the development trend of China's packaging machinery industry is as follows:
Specialization in the production of packaging machinery parts. The international packaging industry attaches great importance to improving the compatibility of packaging machinery and the entire packaging system. Therefore, the specialization of packaging machinery parts production is an inevitable trend of development. Many parts are no longer produced by the packaging machinery factory, but by some general-purpose The standard parts factory produces, some special parts are produced by highly specialized manufacturers, and the truly famous packaging machinery factory will probably be the assembly plant. This is because many control parts or structural parts of packaging machinery are the same as general-purpose equipment and can be borrowed. At present, the pattern of “small but complete” and “big and complete” of the packaging industry in China is very incompatible with the development trend of specialization. The overall structure of this unreasonable enterprise should be adjusted as soon as possible. The product is developing towards multi-function and single high-speed polarization. The ultimate goal of packaging machinery is to increase productivity and product diversification. This has led to the development of packaging machinery product specifications in the direction of polarization, that is, multi-function and single high speed. Some large companies require very high efficiency when packaging products, emphasizing speed and quality. With China's accession to the WTO, such products and enterprises will be more and more in China, and multi-functionality is developed to adapt to the changing market demand.As far as I know, there is a manufacturer in Guangdong that produces weighing scale weighing and packaging machinery. The size of the industry is quite large. It is Guangdong Kenwei Intellectualized Machinery Co.,Ltd., with a fast production cycle and a general model of 20 days. Inside the workshop, the semi-finished products are automatically assembled, and the line and semi-finished products are specially trained and produced by the staff. The purpose is to improve the efficiency of the separate production of the lines and parts, and to have better operation and precise control on site, and have the opportunity to visit the site.
China's packaging machinery industry should take the brand strategy. Enterprises that insist on "quality is life" first have the foundation of creating a brand, coupled with the constant innovation in the competition, the application of high-tech and the exploration of cutting-edge technology, significant enterprises and significant products will be gradually selected. For example, beer beverage filling production line, corrugated board production line, instant noodle production line, cup filling machine, wide laminating machine, 200-liter bulk blow molding machine, BOPP blowing machine, chocolate equipment, homogenizer, etc. Although there are many production enterprises, the high visibility and large sales have shown a significant concentration trend. Significant enterprises and significant brands are gradually forming.
At present, the research and development of food packaging machinery is developing in the direction of high speed, multi-function and intelligent control to meet market demand. In order to meet the requirements of delivery time and reduce the need for process circulation costs, future food packaging machinery is required to be capable of high-speed production. At the same time, for some products, packaging machinery and production machinery are also required to be connected, and continuous work or long working mode can also be adopted. In addition, it is necessary to reduce the scrap rate and failure rate, so that normal productivity can be improved, and the development trend is to further make the packaging machinery more intelligent. Packaging machinery pursues packaging and processing integration. There are a lot of new packaging technologies built on the new thinking of packaging. New packaging thinking means detaching existing packaging technologies and products, and applying other related technologies to packaging to form new packaging technologies, including packaging and cutting technology, packaging curing technology, packaging function protection technology, packaging and processing. Combine technology and packaging functions to borrow technology. There are other technologies, such as the packaging technology of fresh food. In addition, with the advent of new packaging materials, some of the techniques in the packaging process have also undergone new changes. Such as the appearance of self-adhesive stretch wrapping film, the process of wrapping, shrinking, bundling and the like are integrated, and the operation is simplified and quick. This packaging processing integration solves many processing processes and directly borrows the packaging mechanism to realize the integration of packaging and processing, making the packaging more potential and effective.
China's packaging machinery overall technology is still lagging behind developed countries, but China's packaging machinery market demand has promoted the development of the industry and promoted the continuous innovation of production enterprises, changing the backward business philosophy and development thinking, so the future development of China's packaging machinery industry Very optimistic, as long as enterprises can seize the opportunity, I believe that in the near future, China's packaging machinery industry will stand at the forefront of the world packaging industry.
In short, with the rapid development of the national economy, foreign trade has been expanding, the people's living standards have improved significantly, and the packaging requirements for products have become higher and higher. It is urgent to require packaging to achieve mechanization and automation, thus greatly promoting the development of the packaging machinery industry. The position of the machinery industry in the national economy is becoming more and more important. China's packaging machinery industry is building new packaging machinery, leading packaging machinery to the direction of integration, efficiency, and intelligence.
