What is the source of the bull scale?

Multi-head weigher is a dynamic weighing tool. It selects the combination weighing hopper closest to the target weight through calculation, analysis, combination, and screening, and sends a ready signal that the combination weigher has weighed the material and is ready to discharge the weighing hopper. After discharging, the buffer hopper will replenish, weigh and combine the weighing hopper in time to prepare for the next discharging. Multi-head scales come from the fact that people cannot achieve accurate weighing by dividing them. They can only use large to small, or small to large to achieve the specified amount. This kind of manual weighing is not only unable to meet the accuracy The weight, and the inefficiency of the use process, restricts the development of food packaging and consumer demand. In the 1970s, the Japan Agricultural Association raised the subject of weighing green peppers to relevant weighing instrument companies. In Japan, green peppers are usually sold in supermarkets in the form of quantitative packaging in bags. If the quantitative value of each bag of green pepper is 120g, it is very difficult to pack 120g accurately. Since a single green pepper is heavier and has a large difference, less installation is related to the interests of consumers, and more installation is related to the cost of the enterprise. The traditional method is manual weighing, that is, weighing on a static electronic scale. A green pepper followed by a green pepper is added to 115g. It is almost impossible to find a 5g green pepper to add it, so it must be weighed from 115g. Take a smaller green pepper and add another larger green pepper. If the weight is much more than 120g or less than 120g, the above work needs to be repeated, so the weighing efficiency is extremely low, and it is difficult to achieve a result close to the target weight (quantitative value). After a large number of investigations and studies on this, the technicians successfully solved the above-mentioned green pepper weighing problem by using the principle of combined weighing. There are many types of multi-head scales: let’s take a look at its classification: as the name suggests, multi-head scales have many 'heads, 10 buckets, 12 buckets, 14 buckets, 16 buckets, 20 buckets, 24 buckets, etc. According to the type of use environment, it is also divided into waterproof type, anti-corrosion type, anti-collision type, general-purpose type, etc., which are used in food packaging, daily chemical, tobacco, and hardware (particle) industries. According to the shape, it is divided into double door, large column type, double chute, low noise single door type. The emergence of multi-head scales has greatly improved the weighing efficiency of irregular food, ensured the accuracy of product weight, and protected the interests of consumers.
