Weighing and mixing system without weighing meter and main console, only sensor junction box, signal transmitter, wiring cabinet, PLC, analog input module, communication module, touch screen, HZS(HLS) series control dual synchronous control system, The main hardware is composed of two computers, high-performance microcomputer controller, man-machine interface, high-speed and high-precision weighing unit and internationally famous low-voltage electrical appliances. Industrial calculation is used to control the production process.

The weighing and feeding system adopts automatic control to realize the automatic control and supervision of raw material loading, weighing and metering, vacuum feeding, mixing and other 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 are controlled by the computer. Powder metering and conveying is an automatic control process, using powder metering tank measurement. According to the weight of the feed, the computer control automatically opens the corresponding valve, and the linkage starts the corresponding screw conveyor to start the feed. When the weighing reaches the set value, the interlocking feed valve and screw conveyor of the weighing module close. After the measurement is completed, the discharge valve of the metering tank will automatically open, and the feed valve of the transition tank will be opened, and the powder will enter the transition tank for storage. When the powder is added to the dispersed tank, the bottom of the tank will be loaded, and the vacuum will be pumped in the tank. The discharge valve of the transition tank and the feed valve of the tank will automatically open, and the powder will enter the reaction kettle from the bottom of the tank.
In the production process of the continuous dosing machine, the fillers are continuously and accurately fed into the first pair of screw extruders for premixing through the corresponding metering device, the base material is obtained after degassing and cooling, and then into the second twin screw extruder for further mixing and dispersing, so that the raw materials introduced into the system are transported from the raw material storage tank to the hopper scale through the screw feeding device, and the raw materials in the hopper pass the weighing module. Stop feeding when the weight reaches the upper limit, start feeding when the weight is lower than the lower limit. The weight of the measuring hopper is constantly changing, and it is discharged from the measuring hopper by the discharge pump within the time range. This time is not fed, and the weight of the material in the measuring hopper is a downward trend. Within the time range, because the material in the measuring hopper has reached the lower limit, it needs to be fed, and the weight of the measuring hopper increases.
