Multi-head microcomputer combination said-'hot
The multi-head microcomputer combination claims that the performance in both packaging accuracy and speed is greatly improved compared with the traditional measurement method. At present, in the industry, the weighing error of multi-head microcomputer combination weighing is generally set to a positive deviation of 0.5-1.0g (weighing range 500g). At the same time, because the multi-head microcomputer combination scale uses a computer for calculation, the combination speed (ie, weighing speed) is effectively increased. A ten-head multi-head microcomputer combination scale can weigh up to 70 times per minute, and a fourteen-head multi-head microcomputer Combination weighing, weighing speed up to 120 times / min. Fujian Dali Food Factory is a large-scale enterprise specializing in the production of fried potato chips. Before 2004, it had used the traditional measurement method (single weighing cup measurement). Its speed can only reach 25 times per minute, and the average error of single bag weighing The value is greater than 4g, that is, each bag of potato chips (40g) is packed with at least 4g of potato chips due to inaccurate weighing. Calculated based on 4000 tons of output per year, the company loses nearly 400 tons of potato chips per year for this item alone. In order to solve the problem of inaccurate product measurement, the company tried to purchase a multi-head microcomputer combination scale (WP-A10). After using the multi-head microcomputer combination weighing, the enterprise sets the actual weighing error value to 1g, that is, the loss of weighing error per bag of potato chips (40s) is more than 3 grams less than when the multi-head microcomputer combination weighing is not used, which is confirmed by cost accounting. The multi-head computer combination said that it will recover all the investment within half a year. At present, Fujian Dali Group, including nearly 10 branches across the country, uses more than 40 domestic multi-head microcomputer combinations.
Multi-head microcomputer combination weighing quantitative weighing section is a key equipment for food factory automation production. Previously, China relied on imports from Japan, Australia and other countries. Due to the high price, it has hindered the widespread application and popularization of computer multi-head microcomputer combination weighing. Zhongshan Jingwei Packaging Machinery Co., Ltd.'s generation of multi-head microcomputer combination scales, and the high grade of multi-head microcomputer combination scales, made the computer multi-head microcomputer combination scales that were originally regarded as 'noble products' no longer patents of large enterprises. More domestic enterprises pursuing high speed and high efficiency have eliminated the previous quantitative weighing packaging production lines such as cup-type or full labor, and used a combination of high-tech and more automated multi-head microcomputers to weigh quantitative weighing packaging. System to arm yourself.
If domestic food companies want to learn more about multi-head microcomputer combination scales, they must introduce three factors that should be paid attention to when purchasing multi-head microcomputer combination scales.
The first thing to consider when purchasing a multi-head microcomputer combination weigher is whether the multi-head microcomputer combination weigher matches the production line. The general multi-head microcomputer combination weighing quantitative weighing packaging system is mainly composed of multi-head microcomputer combination weighing, vertical packaging machine, vibrating feeder, Z-type conveyor, support platform and so on. The weighing speed of multi-head microcomputer combination weighing mainly depends on the number of weighing hoppers involved. The more weighing hoppers, the faster the weighing speed. If the user already has an existing packaging machine, the speed of the multi-head microcomputer combination weigher should refer to the operating speed of the packaging machine, but the speed of the multi-head microcomputer combination weigher should be slightly higher The operating speed of the packaging machine.
Secondly, we must consider the characteristics of the product's weighing range, material size, shape, and whether or not it is sticky. The feed hopper and weighing hopper in contact with the material should be anti-sticky. Generally, the embossed scale weighing hopper will be selected, otherwise it will affect the speed and accuracy of the multi-head microcomputer combination weighing.
The third factor is the weighing accuracy of the multi-head microcomputer combination weigher. Although the multi-head microcomputer combination is said to be a very mature product, the accuracy of load sensors used in these measurements is not the same. Some multi-head microcomputer combinations are called analog signals. At present, the analog signals are basically pirated scales. The scale mainly has problems with unstable performance, easy to burn motherboards, and second-hand sources of IC chips. The biggest problem is the product. There is basically no ability to improve. Some are digital weighing, such as Jingwei, which mainly produces waterproof multi-head microcomputer combination weighing, all using digital high-precision weighing signals, which is a perfect combination of accuracy and speed.
The combination of multi-head microcomputers said that basically no maintenance is needed during use, and only daily cleaning is required. In addition, two points that food companies should pay special attention to when using multi-head microcomputer combination weighing are: First, keep the continuity, stability and reasonableness of the supply as much as possible. Too much or too little material in the bucket will cause the situation that the multi-head microcomputer combination weighing is difficult or impossible to combine, thereby reducing the speed and accuracy of weighing; second, the disassembly and assembly of the weighing bucket should be as light as possible with excessive force The load sensor will be damaged and the weighing accuracy will not be used even. Third, after daily use, the main vibrating plate, line vibrating plate, feed hopper, weighing hopper, etc. should be cleaned only where they are in direct contact with the test. Before each use, check the hook of each weighing hopper for foreign objects , And remove the dust on the hooks of each weighing bucket after use.
