[0043] When the cans to be cleaned are in place, the control system turns on the water supply device, which supplies water to the cleaning box 42 through the water inlet pipe 43, and the water is sprayed from the strip nozzle 41 on the cleaning box 42 to the cans to clean the sides of the cans; the control system turns on the pressing cylinder 102, and the output shaft of the pressing cylinder 102 drives the main tray 104 to descend, and the descent of the main tray 104 drives the T-shaped slide bar 74 to descend until the brush strip plate 76 at the bottom end of the T-shaped slide bar 74 contacts the top cover of the can, and the control system turns on the drive motor 106, and the output shaft of the drive motor 106 drives the gear ring 71 to rotate through the drive gear 107, and the rotation of the gear ring 71 drives the brush strip plate 76 to rotate, and the rotation of the brush strip plate 76 drives the flexible bristles to brush the top cover of the can, and the top cover is cleaned. After that, the control system drives the brush plate 76 to continue to move downward through the pressing cylinder 102. The brush plate 76 slips relative to the gear ring 71 after being pressed. When the brush plate 76 slides, its edge is squeezed against the upper part of the limit buckle 731, causing the limit buckle 731 to rotate around the buckle rotating rod 733 until the bottom end of the limit buckle 731 clamps the top cover of the can. After that, the drive motor 106 is started again, thereby driving the can to rotate on the turntable 531. At the same time, the gear ring 71 drives the cleaning shaft 113 to rotate in the opposite direction through the cleaning gear 114. The cleaning shaft 113 drives the brush wheel 111 through the roller 112 to clean the side of the can. The can rotates forward and the brush wheel 111 rotates reversely, so that the brush wheel 111 has a higher cleaning efficiency for the can.

[0044] When the cleaning is completed and the cans located at the can outlet 3 need to be unloaded, the control system starts the unloading cylinder 92, the output shaft of the unloading cylinder 92 contracts and drives the fan-shaped slider 91 to move, the fan-shaped slider 91 drives the unloading column 556 in the groove to move, the unloading column 556 drives the sliding unloading rod 554 to move, the sliding unloading rod 554 drives the second positioning block 552 to move through the push rod 555, and the second positioning roller 553 on the second positioning block 552 pushes the cleaned cans out of the positioning device 5, so that the cans enter the transportation device, thereby realizing the unloading of the cans.
