Automatic Filling machine design unique spray gun device is easy to operate, filling fast and accurate; And maximize to ensure the drip of residual liquid after the completion of perfusion. When operating, the operator only needs to simply place the barrel at the beginning of the conveying line, automatically transfer it to the filling position, the spray gun starts and automatically inserts the barrel, and the empty barrel is automatically peeled. Then open the filling valve and fill accurately with two speeds; After filling, the spray gun is automatically lifted to the outside of the barrel, the drip pan is automatically connected to the bottom of the spray gun, and the barrel is transferred out of the back end of the weighing table.

The Filling system is controlled by PLC programmable device, which is an ideal weighing equipment integrating weighing and filling. The tare weight is automatically removed during filling, and the material is injected into the container with a large amount of rapid filling and then a slow and small dose correction measurement. When the container is sent into the weighing platform, the conveyor runs at the same time, and the photoelectric sensor detects that the signal sent after the arrival of a container controls the motor to stop. The photoelectric sensor detects the signal sent when the container reaches the filling position of the filling machine, the PLC controls the conveyor to stop, the automatic peeling and filling valve is driven down by the stepper motor, and the drop limit is reached by the stroke switch to send a signal, and the PLC controls the filling valve to fully open for filling. When the set value is reached, the solenoid valve moves the filling valve to open half for filling. At the same time, the stepper motor drives the filling valve to rise through the lead screw according to the pre-set speed of the weighing filling machine. When the filling weight requirement is reached, the filling valve is closed, the filling valve reaches the upper limit, the stroke switch stops sending a signal, and the PLC simultaneously controls the motor weighing conveyor to run at the same time until the finished product is output. Then the container is placed on the electronic weighing platform, and the barrel mouth is aligned with the filling mouth. At this time, the program starts, the filling mouth automatically drops, and the filling valve is opened to feed. The filling nozzle rises to complete the filling process.
