Weighing Filling machine using Weighing system, PLC control cylinder filling head fast, medium and slow feeding, using pneumatic speed regulation function, electronic automatic metering technology, controlled by PLC program, pressure detection control, Chinese touch interface, weighing module measurement. It is composed of high and low pressure control system, nitrogen system, filling device, pressure control system, weighing control system, PLC control system, etc. The control network is composed of programmable controller and Electronic scale, and is connected to the weighing instrument, control computer, PLC, inverter and other intelligent equipment with high processing speed through the field bus. PLC is mainly responsible for the detection, display and alarm of filling faults, and at the same time output signals to the inverter, which completes the role of adjusting the speed of the electronic scale at the point. In order to facilitate the simple operation of the user, the weighing touch screen is specially used to connect with the weighing instrument, which will greatly facilitate the user's operation. In the use of the liquid level of the high and low level signal on/off the intermediate relay normally closed electric shock control contactor electricity to control the replenishing motor, extend the filling duration and improve production efficiency.

The automatic filling machine connects the weighing module to the weighing instrument with a data line. When the detection device detects the in-situ detection signal of the pre-filled barrel before filling, the transmission of the conveyor belt will be suspended. After the motor of the main shaft lifting mechanism lowers the rotating spindle of the barrel taking mechanism to the position, the barrel taking fixture will clamp the pre-filled barrel and then raise it to the position, and the transmission of the conveyor belt will begin. The barrel taking shaft transfers the pre-filled lubricating oil barrel to the quality detection table, the barrel taking shaft drops to the original position, the barrel taking jig releases the pre-filled lubricating oil barrel into place, conducts quality detection, and then measures the quality input signal, the barrel taking jig clamps the barrel before filling, the barrel taking shaft rises into place and rotates, the lubricating oil barrel is transferred to the conveyor belt before filling, the conveyor belt is suspended, and the barrel taking shaft drops into place. The barrel taking clamp releases the barrel before filling, the barrel taking rotary shaft rises, the conveyor belt starts, and the quality detection action before filling is completed. During the measuring process, the pressure signal of the weighing module is continuously transmitted to the weighing instrument. When the preset quantitative weight is reached, the weighing display controls to stop the pump and close the pneumatic valve.
