Then the upper and lower covers are precisely aligned with the can body through spinning equipment and are edge sealed to form a sealed can body. After the can body is cleaned and dried, the content injection and environmentally friendly propellant filling are completed in turn. Then the valve system, spray head or nozzle are installed and locked and sealed. Finally, the qualified aerosol cans are subjected to multiple quality inspections such as pressure resistance test, leakage test and spray effect test, and unqualified products are removed. The qualified aerosol cans are labeled, boxed and finally stored for sale.

[0005] The existing upper and lower cover conveying equipment conveys the upper and lower covers to the spinning machine through a conveying device to spin the two sides of the can body. Therefore, there are generally two conveying lines, one conveying the upper cover and the other conveying the lower cover. When conveying, the top cover protrusion faces upward and the bottom cover protrusion faces downward, so that the spinning die can accurately correspond to the processing position of the upper and lower covers, and the forming is completed by downward or lateral pressure. Once the upper and lower covers are placed in the wrong direction, the spinning die cannot be aligned with the processing surface, the die is empty or the position is pressed incorrectly.
