The automatic Filling machine adopts PLC control, which can adjust the whole filling machine or fine tune the single head, so that the master will automatically stop the alarm without filling the barrel, missing the barrel and blocking the barrel. It is mainly composed of explosion-proof device, electronic control system, photoelectric detection, weighing device, filling device and so on. The electrical control part is controlled by PLC programmable logic program controller, the input signal of analog quantity is collected in real time filling quality, and the output of switching quantity controls the action of pump and solenoid valve. The PLC system has two working modes, which can display the current filling quality, the number of filling barrels and other on-site working status through the screen in real time. The corresponding operation can be carried out on the upper computer. Through the interface to select the filling mode and start, stop and other buttons operation. The ability to change the filling quality, number of barrels and manually remove tare weight (i.e. the quality of the filling bottle) when using different filling barrels.

The automatic filling machine takes the solenoid valve and the motor as the controlled object. The solenoid valve and motor are controlled with MCGS, and the number of barrels is measured in real time using a weighing module mounted next to the conveyor belt. At the same time, the number of barrels collected by the weighing module is sent back to the control system for analysis and display. If the number of barrels displayed in the specified time exceeds the standard number, it means that the flow rate of the barrel is too high, and the motor speed needs to be adjusted to reduce its speed; If the number of barrels displayed in the specified time is lower than the standard number, it indicates that the flow rate of the barrel is too low, and the speed of the motor needs to be adjusted to increase its speed; If the number of buckets is lower than the minimum value within the specified time, an alarm will be issued, indicating that the speed of the bucket flow is too low; Conversely, if the number of buckets is higher than the maximum within a specified period of time, an alarm is also sounded, indicating that the bucket flow speed is too high. The whole device uses the weighing module to collect the number of buckets, MCGS configuration software to control and display the number of buckets, start and cut off the power supply.
