Talk about the principle of combination
With the development of automated production in various fields in China and the continuous increase in labor costs, the quantitative combination of other industries in food, medicine, and seed machines is also becoming more and more urgent. The smart combination scale market in China is cultivating a huge development space.
The computer combination scale, the researchers proposed to use the combination weighing principle to solve the weighing problem of uneven goods, that is, the computer combination scale, also known as the selection combination scale, is a fast measuring speed and high accuracy mechanism, in food, medicine, Chemical industry and other industries should have applications, especially granular objects with irregular shapes and uneven quality, such as candy, frozen aquatic products, chocolate, etc.
At present, Japan and Germany are concerned about the technology of combination scales, but China's technology in this respect is still relatively backward. The main factor restricting China's development is the high development cost, which is difficult for ordinary companies to bear. At the same time, another factor is The technology is backward, and the combined model is not properly established.
The working principle of the combination scale. The combination scale is usually composed of multiple weighing units. Currently, 8 weighing units are widely used. Each weighing is composed of a buffer hopper and a weighing hopper. Each buffer hopper, The feeding port and weighing hopper are controlled. The weighing process is as follows: the weighing object is transported by the conveyor to the buffer hopper of the combination scale, and then the separation feeder starts to work, so that the material enters the feed hopper for storage. When the last weighing is completed, the feed hopper will open, The weighing object falls into the weighing hopper for weighing. After the weighing is completed, the weighing result is transmitted to the computer through the sensor, which is arranged and combined by the computer. The system will calculate according to the set parameter value and select the closest quantitative The combination of values ?without re-selection is sent to the buffer hopper, and then the signal is output, the corresponding weighing hopper is opened, and the weighed object is sent to the subsequent packaging process.
