The automatic batching system is centered on a microcomputer and combined with strong current equipment to form a closed-loop system. The test objects are the weight signal of the electronic scale, the input signals of various switching values, and the control objects are electromechanical devices such as feeders, scale hopper gates, mixer gates, and grease adding switch valves. Different automatic batching systems can achieve different indicators, but their most basic requirements are: static batching accuracy ≤ 0.1; dynamic batching accuracy ≤ 0.3; can store a certain number of recipes and is not affected by power outages; have accurate alarm signals; Each production section has a chain protection function and can produce continuously; during production, it has a power-off protection function and an automatic error correction function; it has an automatic detection function for receiving and sending signals; it has a static accuracy calibration test function; it has an automatic and manual switching function. .

In the actual production process, the batching system can be divided into three processes: batching process, mixing process, and mixer discharge process. The central link of the automatic batching system is the batching scale. During batching, the production control application automatically controls the batching according to the production formula requirements. The required materials are fed separately by the corresponding silo augers. The changes in the weight of the scale hopper are processed by the computer. Collected, when the required material amount reaches the set value, go to the next material configuration. When all materials are configured, the batching process ends. If there is no material in the mixer, and the mixer door is closed tightly and the mixer main engine is working, open the scale bucket door and the materials fall into the mixer and enter the mixing process. If grease addition and trace component addition are required, they can be started separately, automatic addition can be performed, and warnings can also be given. When the mixing reaches the set mixing time, the mixer door will be opened and the timer will automatically start to enter the mixer discharging process. Set the door opening time according to the mixer discharge speed, and close the mixer door when the set door opening time is reached. This completes an automatic batching. At the same time, the above three processes do not work in isolation, but are organically combined. While the mixer is mixing materials, the batching scale is also batching ingredients at the same time, ensuring that the batching section and the mixing section are not disconnected, and ensuring the continuity of automatic production.
