The automatic filling machine executes according to the batch work order, designs the program according to the S88 standard, executes, suspends, cancellations, ends, stops the process and status during the filling operation, integrates information accessory equipment, such as printers, scanning guns, RFID and other information identification equipment, and gives the material identifiable information into the weighing process. Through the industrial Ethernet network, the operation stations of each process are connected. An operation station is placed in each process to connect each process equipment. The function of each station is realized through the operation station.

The Filling system will manually send the empty barrel to the filling position, align the barrel mouth with the spray gun mouth, press the "start" button, and the spray gun will enter the barrel under the drive of the cylinder; When the detection gun is in place, the bottom valve is opened, and the nitrogen charging valve is started to fill the dry nitrogen into the barrel through the filling port, so that the air in the barrel is replaced by nitrogen, and the drying of the inner wall of the barrel can be accelerated to ensure the filling safety. When filling nitrogen, the air in the container should be replaced, and the specific amount of nitrogen can be adjusted by the controller time. After a certain amount of nitrogen is charged, the nitrogen charging valve is closed, and the control instrument automatically removes the tare weight from the empty drum of the scale, and then the fast and slow charging ball valve is opened at the same time; The spray gun starts to fill at the liquid level after staying at a very low position for a period of time, stops at the mouth of the barrel after staying at 3 places with the liquid level rising, and then slowly adds the material; When the filling amount reaches the preset advance amount, the ball valve and the bottom valve are closed; The gun rises out of the barrel; The vacuum suction device starts to ensure that no residual droplets leak. Each sealing place of the entire pipeline is sealed with polytetrafluoroethylene material to achieve no leakage requirements. After filling, manually push the full drum to the solid drum roller table, and manually pneumatic screw the cap; Push the solid drum with the lid screwed to the unloading buffer position; The packed drums are carried away by forklift. After filling each shift, place the barrel under the filling head, close the manual material feed valve, do a filling process, release the material, and shut down. Restore the initial state of the weighing Filling machine, and the whole process is over.
The automatic filling machine is a straight line, continuous liquid filling equipment, the barrel in turn through the 2#, 3#, 4# filling nozzle for rough filling, to the 5# filling nozzle for precise filling, by the conveyor belt to the next process. The empty barrel is put into the automatic liquid filling conveying chain manually, the barrel pusher pushes the empty barrel to the 2# filling station on the filling weighing line, and the 2# Electronic scale rises. After the delay of placing the barrel to the point, the weight value of the empty barrel is taken into the tank for automatic peeling, and then the filling head is opened to start the rapid pre-filling with large flow. When the pre-filling amount is reached, the 2# electronic scale is lowered. The filling amount is determined according to the filling time of the filling nozzle. Then the filling bucket enters the 5# filling station, the 5# electronic scale is raised, the filling nozzle is filled to the setting value of the coarse close valve and then transferred to the low flow and slow filling. After the filling to the setting value of the fine close valve, the quasi-loading head is completely closed. After the filling is completed, the filling weighing line will start again, and the automatic filling weighing line will drive the heavy barrel to the next process, so that the filling weighing work is completed.
