The difference between multi-head microcomputer
The rapid development of modern industry, the packaging industry packaging accuracy, packaging speed, packaging range and other aspects also have higher requirements, traditional quantitative automatic packaging scales have been difficult to meet these requirements, and the combination of multi-head microcomputer said it was developed under this requirement. It has the following differences from traditional quantitative automatic packaging scales:
During the weighing process, the dust of some objects will stick to the wall of the weighing hopper and will not fall down, which will affect the accuracy of the next weighing. The solution of the multi-head microcomputer combination weigher to solve this problem is as follows: ①The weighing hopper is generally opened 4-5 times when releasing the material, so as to reduce the dust residue of the weighed object. ②The multi-head microcomputer combination scale will automatically zero the weight of the weighing hopper, that is, the dust sticking to the weighing hopper will be regarded as zero weight, which will not affect the accuracy of the next weighing.
Traditional quantitative automatic packaging scales generally go through the weighing process of coarse measurement and fine measurement, especially the process of fine measurement requires a little addition, which takes a long time and affects the weighing speed. For example, the weighing speed of a quantitative automatic packaging scale under 1 kg is generally 20 to 30 packs / minute, and the multi-head microcomputer combination weigher generally weighs 100 to 120 packs in a 14-weighing unit scale in the computer's fast optimal combination calculation. Minutes, 4-6 times faster than the quantitative automatic packaging scale, and easy to match with various packaging machines. Greatly improve the packaging efficiency, more suitable for the needs of modern production management.
In the case of the same accuracy, the weighing range of the multi-head microcomputer combination is larger than that of the traditional quantitative automatic packaging scale. In general, the weighing range of the traditional quantitative automatic packaging scale under the same accuracy is controlled within 4 times, while the multi-head microcomputer combination It is said that the weighing range in the small weighing section can reach more than ten times. It can also be seen from a large number of test results that there is a difference in the weighing range between the two. For example, in the weighing range of more than ten grams to one kilogram, the multi-head microcomputer combination scale can meet the requirements of the accuracy level of X (1) level, especially in the small weighing section. If you want to keep the accuracy level unchanged, the traditional quantitative automatic packaging scale can only achieve a certain aspect of the manufacturer's requirements by reducing the weighing range and forming a multi-stage weighing. Most manufacturers rarely accept this phenomenon. This brings limitations to its practical application, and can not meet the requirements of different packaging specifications (10-1000g) in some production areas but requiring similar accuracy.
The multi-head microcomputer combination scale of the combination scale manufacturer is generally used in the computer's fast optimization combination operation. The scale of 14 weighing units can reach 100 to 120 bags / min, which is 4 to 6 times faster than the quantitative automatic packaging scale. Cooperate with various packaging machines. Greatly improve the packaging efficiency, more suitable for the needs of modern production management. When the difference between the weighing range of the multi-head microcomputer combination scale and the traditional quantitative automatic packaging scale is the same, the weighing range of the multi-head microcomputer combination scale is larger than the traditional quantitative automatic packaging scale. In general, the traditional quantitative automatic packaging scale is in the same The weighing range under accuracy is controlled within 4 times, while the multi-head microcomputer combination weighs the weighing range in the small weighing section up to ten times.
