[0037] Working principle: After the electrolyte is loaded into the barrel body 2, the gas pipe 1 17 and the gas pipe 2 18 are respectively inserted into the two connecting joints 4, and then the movable sleeve 3 outside the two connecting joints 4 is rotated to move the movable sleeve 3 toward the bottom of the gas pipe 1 17 and the gas pipe 2 18. During the movement of the movable sleeve 3, the multiple movable blocks 13 inside the connecting joint 4 can be pushed to move. After the movable block 13 is moved out of the limiting groove 19 and moved to the bottom of the limiting ring 12, the two connecting joints 4 can be fixed on the outer periphery of the gas pipe 1 17 and the gas pipe 2 18, respectively, so that the gas pipe 1 17 and the gas pipe 2 18 are connected to the connecting pipe 6. When the gas pipe 1 17 and the gas pipe 2 18 are inserted into the two connecting joints 4, the two top blocks 10 can respectively push the two sealing blocks 11 to move into the gas pipe 1 17 and the gas pipe 2 18 so that the gas pipe 1 17 and the gas pipe 2 18 are connected with the connecting pipe 6, and then the barrel 2 can be inflated through the gas supply pipe 8. During the inflation process, the pressure sensor 5 can detect the air pressure inside the barrel 2. When the air pressure range in the barrel 2 is 0.09-0.1MPa, it is considered to have reached the preset inflation threshold. The pressure sensor 5 sends a command to the controller 1, and the controller 1 sends a closing command to the solenoid valve 7 to close the air supply pipe 8. After inflation, let it stand for 24 hours, and then start the controller 1 to detect the air pressure in the barrel 2. If the air pressure in the barrel is lower than the threshold of 0.09MPa, it means that the packaging barrel is not well sealed and does not meet the quality and safety standards. It is judged as a defective product and needs to be replaced. If the air pressure in the barrel remains within the threshold range set by 0.09 to 0.1 MPa, it means that the packaging barrel is well sealed, and the controller 1 starts the solenoid valve 7 to release the pressure. When the air pressure in the barrel body 2 reaches the threshold range set by 0.04 to 0.06 MPa, the pressure sensor 5 sends a command to the controller 1, and the controller 1 sends a closing command to the solenoid valve 7 to close the air supply pipe 8.
