The weighing and Filling machine is measured by the weighing sensor platform under the control of microcomputer program. Remove tare before filling. When the material is injected into the container, the large dose is fed quickly and the small dose is corrected and measured slowly. The operator only needs to put the container into the platform, the mouth is opposite to the feeding nozzle, at this time the program starts, the feeding nozzle is lowered, the filling valve is opened and the feeding is stopped when the set quantity is reached, and the feeding nozzle is raised to complete the filling process. It is mainly composed of weighing module, control system, filling mechanism and transmission mechanism. The control system processes the weighing data by using the weighing module, and adjusts the opening and closing of the filling mechanism to make the filling reach the weight required by the weighing. Fill according to a certain capacity to meet the needs of production and sales.

The metering filling machine drives a piston through the cylinder to extract and pump out the material, controls the material flow direction with a check valve, controls the stroke of the cylinder with a magnetic spring switch to adjust the filling amount, connects the weighing module with the data line of the weighing instrument, and continuously transmits the pressure signal of the Electronic scale to the weighing instrument during the measuring process. The control instrument controls the pump and closes the pneumatic valve when the preset fixed weight is reached. The weighing and filling machine is controlled by a PLC programmable device. The electric drum of the scale body runs simultaneously when the container is sent in. The photoelectric switch on the weighing module detects the signal sent by the passing container and controls the signal sent by the motor when the container reaches the filling position. The well is signaled by the travel switch, and the PLC controls the filling valve to be fully opened for filling. When the set value is reached, the solenoid valve acts, the filling valve is half-opened for filling, and at the same time, the stepper motor drives the filling valve to rise through the screw at the pre-set speed: when the filling requirement is met, the filling valve reaches the upper limit, the travel switch stops and sends a signal. PLC controls the electric rolling of the motor scale body at the same time, and the finished product is output, and then the container is put into the electronic scale platform, the barrel mouth is aligned with the filling mouth, at this time the program starts, the filling nozzle will automatically drop, the filling valve will be opened to feed, and the filling nozzle will automatically stop when the set amount is reached, and the filling nozzle will rise to complete the filling process.
