[0053] When the aluminum can to be cleaned is in place, the control system activates the water supply device. The water supply device supplies water to the cleaning tank 42 through the water inlet pipe 43, and the water sprays from the strip-shaped nozzles 41 on the cleaning tank 42 onto the aluminum can to clean the side of the aluminum can. The control system activates the pressing cylinder 102, and the output shaft of the pressing cylinder 102 drives the main tray 104 to descend. The descent of the main tray 104 drives the T-shaped sliding rod 74 to descend until the brush strip disk 76 at the bottom of the T-shaped sliding rod 74 contacts the top cover of the aluminum can. The control system activates 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. The rotation of the gear ring 71 drives the brush strip disk 76 to rotate, and the rotation of the brush strip disk 76 drives the flexible brush bristles to brush the top cover of the aluminum can. After the top cover is cleaned, the control system drives the brush strip disk 76 to continue moving downward through the pressing cylinder 102. When the brush strip disk 76 is pressed, it slips relative to the gear ring 71. When the brush strip disk 76 slips, the edge of it squeezes 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 aluminum can. After that, the drive motor 106 is started again, thereby driving the aluminum can to rotate on the turntable 531. At the same time, the gear ring 71 drives the cleaning rotating shaft 113 to rotate in the reverse direction through the cleaning gear 114. The cleaning rotating shaft 113 drives the brush wheel 111 to clean the side of the aluminum can through the roller 112. The aluminum can rotates forward, and the brush wheel 111 rotates in the reverse direction, making the cleaning efficiency of the brush wheel 111 for the aluminum can higher.

[0054] When it is necessary to unload the aluminum can located at the can outlet 3 after cleaning, the control system activates the unloading cylinder 92. The output shaft of the unloading cylinder 92 contracts and drives the sector slider 91 to move. The sector 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. The second positioning roller 553 on the second positioning block 552 pushes the cleaned aluminum can out of the positioning device 5, enabling the aluminum can to enter the transportation device, thereby realizing the unloading of the aluminum can.
