# With the traditional computer linear combination said automatic packing scale of quantitative comparison

2020/07/18
Along with the rapid development of modern industry, packaging industry in packing, packing speed and accuracy also have higher requirements, as the traditional quantitative automatic packing scale has been difficult to meet these requirements, it is according to the linear combination of computer in this case, it with the traditional quantitative automatic packing scale is the following difference: 1, automatic weighing principle of different quantitative packing scale is feeding weighing, continuous feeding, before reaching the target weight data when vary a little with the target weight must append a known objects, namely coarse measurement before measurement, such as called larger or heavier when there is a bigger error, this is affecting the weighing accuracy. Which is composed of multiple independent computer linear combination said feed discharging structure weighing units, general computer linear combination said consists of 8 ~ 32 weighing unit. Computer by using the theory of permutation and combination to the weighing unit automatic optimum combination of the amount of load, it is concluded that the best and most close to the combination of quantitative values for packaging. Ten weighing unit such as a computer, according to a linear combination of each weighing unit for weighing, each weighing hopper and will be a heavy weight data into the computer, the computer optimization combination, according to the combinatorial mathematics, ten weighing unit can achieve 1023 kinds of combinations, computer is chosen from among the 1023 kinds of combination the closest to the combination of the objective weight values. This item according to the fine measurement weighing were single weight is bigger, and it is difficult to accomplish the work of quantitative values. Computer according to linear combination is the most close to the target weight combination as the final result. 2, automatic weighing speed difference between the traditional quantitative packing scale generally go through rough measuring, measuring the weighing process, especially the fine measurement process need to add little by little, takes longer, weighing speed. For example 1 kg quantitative automatic packing scale under the weighing speed, generally in the 20 ~ 30 packages/minutes, a linear combination and computer said in computer combination optimization arithmetic average 14 unit weighing scales can reach 100 ~ 120 bags/min, than quantitative automatic packing scale weighing 4 ~ 6 times as fast, and easy to match the various kinds of packing machine. Greatly improve the efficiency of the packaging, more suitable for modern production management requirements. 3, weighing accuracy under the condition of the same, the difference between a computer according to linear combination of the quantitative weighing range automatic packing scale big many, generally quantitative automatic packing scale under the same accuracy of the weighing range of control within the four times, and in a small computer linear combination said weighing weighing range can be up to a dozen times. From a large number of experimental results can also tell the weighing scale difference exist. Such as 10 g to 1 kg of weighing range, computer linear combination according to X ( 1) Levels of accuracy requirements, especially in small weighing segment is rare. To the accuracy level unchanged, only narrow scope of weighing automatic quantitative packaging weighers, formation period of weighing, relying on more than one series of products, production can realize the request of manufacturers one. General manufacturers are almost not accept this kind of phenomenon, this creates the limitations for its practical application, different packaging specifications reach certain production areas ( 10 - 1000克) The use of the accuracy requirement. Advantage computer linear combination said although the be clear at a glance, but before computer linear combination said, mainly imported products high price hinder the linear combination said is widely used in China and the world. Zhongshan refined packaging machinery co. , LTD in recent years, with its stable product and reasonable price, the launch was popular in the world, has now become a linear combination of the largest professional manufacturing base in China. Jing wei linear combination according to work is very meticulous, parameters under the automatic recovery, automatic stop, in turn, hopper choose don't deal with clients such as more focus on the function of the system; Is configured with multiple languages convertible large color LCD display screen, super computer connection, according to the material of different increases the rotating main vibration machines and other technology is relatively mature, leading function; Adopted high precision digital weighing sensors, speed up to 130 bags/min, the average accuracy of plus or minus 0 or less. 5 g, has a very high cost performance. Jing wei linear combination according to the technical side of the mounting, let originally is regarded as a linear combination 'noble products' computer says no longer become the patent of big enterprises, more the pursuit of high speed, high efficiency of food enterprises at home and abroad, have eliminated material fee before artificial quantitative weighing packaging production line, which adopts a linear combination of the high-tech, higher automatic degree according to the quantitative weighing and packing system.
