1. Application range and mode selection of linear multihead weigher

Linear multihead weigher can complete measurement, filling and other tasks. It is suitable for packaging various powders and small particles with good flow or poor flowability and uniform density. It is widely used in quantitative packaging of granular and powdery materials such as pesticides, fertilizers, veterinary drugs, feed, premixes, additives, washing powder, salt, monosodium glutamate, chicken essence, sugar, seeds and rice. The linear multihead weigher produced by our company have a variety of different modes to choose from, such as independent mode linear weighers, mixed mode linear weighers or combined mode linear weighers packaging machines. You can choose two-head linear weighers, four-head linear weighers, and six-head linear weighers, eight-head linear weighers and ACZ-B small linear weighers. The linear multihead weigher can automatically work with the packaging machine, and the speed can reach about 10-40 bags/min.

On the working principle and accuracy of linear

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, while the linear combination scale is generally used in the computer's fast preferred combination calculation. The scale of 14 weighing units can reach 100 to 120 packs / minute. It is 4 to 6 times faster than the weighing speed of the quantitative automatic packaging scale, and is easy to match with various packaging machines. Greatly improve the packaging efficiency, more suitable for the needs of modern production management. In the weighing hopper, the material generates a weight signal through the sensor, and then transmits it to the main board of the control device through the lead. The CPU on the main board reads and records the weight of each weighing hopper, and then selects through calculation, analysis, and combination. Combined weighing hopper that is close to the target weight, when receiving the unloading signal sent by the packaging machine, the CPU sends a signal to start the weighing hopper motor driver to open the selected weighing hopper to unload the product into the hopper and enter the packaging machine (If there is a collection hopper, the weighing hopper is assembled and directly discharged to the collection hopper. When there is a request for a discharge signal, the hopper motor is started to discharge the material to the packaging machine). When the weighing hopper (collecting hopper) is finished with materials, the linear combination weigher will send a signal to the packaging machine that has been discharged. After receiving the signal, the packaging machine will start to seal and cut the bag. When the packaging mechanism is completed, a bag After that, it sends a request discharge signal to the linear combination called linear combination called blanking, and so on. In the case of the same accuracy, the linear weighing range is larger than the quantitative automatic packaging scale. In general, the quantitative automatic packaging scale is controlled within 4 times under the same accuracy, while the linear combination weighs in the small scale The weighing range of the segment can reach more than ten times. The combination said that the manufacturer can also see from the 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 linear combination 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 quantitative automatic packaging scale can only reduce the weighing range and form a multi-segment weighing, and only rely on the production of multiple series of products to meet certain requirements of the manufacturer. 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.
