After the materials in the feeding Weighing system are weighed and measured, they are added in turn according to the formula shown by the instrument, and the weight of each powder is recorded by the computer. After the high-speed dispersion is completed, the computer automatically opens the bottom valve of the reaction kettle, the sander and the transmission pump, and the materials are transferred to the paint mixing kettle. After the sanding is completed, the computer controls the automatic addition of additives. The computer records all material additions and production volumes. Automatic control is adopted to realize the automatic control and supervision of raw material feeding, weighing and metering, vacuum feeding, dispersion and mixing processes. The dispersion time and cylinder number can be selected and adjusted on the computer according to the production requirements. The opening and closing of the motor equipment and the opening and closing of the feed valve in the process are controlled by the computer. The finished product is filtered and filled by automatic filling line, and the palletizing process is robot palletizing.

Automatic Feeding machine is mainly composed of reaction kettle, coarse feeding mechanism, fine feeding mechanism, weighing cylinder, weighing module, feeding mechanism, PLC control system and pneumatic system. When the automatic Feeder works, the coarse and fine feeding mechanism is fed at the same time. According to the output signal of the weighing module, the PLC control system controls it respectively according to the set value of the weighing. When the weighing sensor reaches a certain value, the coarse feeding mechanism stops feeding, and the fine feeding mechanism continues to feed until the system set value is reached. The filling mechanism turns over the weighing cylinder and pours the material into the receiving cup at the qualified station to complete a qualified weighing process. If the feeding mechanism is out of tolerance, the feeding mechanism will automatically pour the weighing material into the unqualified station receiving cup, and the system will give a prompt message. When the material level in the storage bin is reduced to a certain amount, the alarm will issue an audible and visual alarm to prompt the operator to add material to ensure the continuous work of the automatic feeder.
