After the materials in the saw shaft weighing and Feeding machine system are weighed and measured, they are added in sequence according to the formula displayed on the weighing instrument. 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 sand mill and the transfer pump to transfer the materials to the paint mixing kettle. After the sand grinding is completed, the computer controls the automatic addition of additives. After passing the inspection, filtration, weighing and packaging begin. The computer records the amount of all materials added and the production volume of the products. By adopting automated control, the processes of raw material feeding, weighing and measurement, vacuum feeding, dispersion and stirring are automatically controlled and supervised. The dispersion time and cylinder number can be selected and adjusted on the computer according to production requirements. The opening and closing of the motor equipment and the feeding valve during the process are all controlled by the computer. The finished product filtration and filling are carried out by a fully automatic filling line, and the palletizing process is done by robots.

The automatic Feeder mainly consists of a reaction vessel, a coarse feeding mechanism, a fine feeding mechanism, a weighing cylinder, a weighing module, a discharging mechanism, a PLC control system and a pneumatic system. When the automatic feeder is in operation, the coarse and fine feeding mechanisms first feed materials simultaneously. According to the output signal of the weighing module, the PLC control system controls them respectively according to the set values of the weighing. When the weighing value of the load cell reaches a certain level, the coarse feeding mechanism stops feeding, and the fine feeding mechanism continues to feed until the set value of the system is reached and then stops. The discharging mechanism flips the weighing cylinder and pours the material into the qualified receiving cup at the working position, completing a qualified weighing process. If the feeding mechanism exceeds the tolerance in feeding, the discharging mechanism will automatically pour the weighed material into the receiving cup of the unqualified station, and the system will give a prompt message. When the material level in the storage bin drops to a certain amount, the alarm will issue an audible and visual alarm to prompt the operator to add materials, ensuring the continuous operation of the automatic feeder.
