The automatic Filling machine adopts coarse and fine two-step filling to ensure the filling speed and accuracy. When filling, the tank mouth is submerged to fill. After filling, the receiving tray is extended to prevent liquid contamination of the packaging and conveying line. It adopts touch screen man-machine dialogue, automatic diagnosis function, parameter setting and cumulative shift production, working status display, etc., automatic tare, cumulative number of barrels, weight, display filling amount, automatic zero tracking, automatic correction of fall, over and under, abnormal operation alarm function, adding the receiving tray at the bottom, with discharge pipe valve, storage materials can be easily discharged.

The automatic filling machine mainly adopts the weighing and quantitative method, and realizes the quantitative filling of liquid by collecting the data of the measurement module. The filling quantity needs to be measured and displayed in real time. The Filling system uses a weighing module and weighing instrument with a measuring range of 0~40kg and a standard voltage signal of 0~10V. The filling quality can be measured through the EM235 analog transmission channel, and the port of EM235 is set to 0.0010. In order to ensure the filling accuracy, the system adds a solenoid valve at the front end of the pump to ensure that the liquid can be immediately switched on and cut off when starting/stopping. The pump selection parameter is 12VDC, the flow rate is 3.1L/min, the maximum pressure is 0.48MPa, and the intermediate relay is used as the conversion to realize the control of the solenoid valve and the pump. The manual/automatic switch is realized through the two selection buttons, and secondly, the start and manual filling are realized through the buttons.
