The support column is slidably inserted into the sleeve, and the two are connected to the base 4 and the support base 5 respectively. Each output end of the multi-jaw chuck is equipped with a vertical free roller 14. When the support base 5 moves upward, the multiple free rollers 14 extend from the empty area.

[0019] The empty area is equipped with a tread cleaning component that can be adjusted left and right on one side, and a sidewall cleaning component that can be adjusted up and down on the other side.

[0020] More specifically, the tread cleaning assembly and the sidewall cleaning assembly have the same structure, both including a roller brush 18, a drive motor 17, and a bracket 19; the roller brush 18 and the drive motor 17 are both mounted on the bracket 19 and are connected by transmission; the roller brush 18 of the tread cleaning assembly is arranged vertically, and the roller brush 18 of the sidewall cleaning assembly is arranged horizontally; the tread cleaning assembly and the sidewall cleaning assembly are respectively connected to a horizontal drive mechanism and a lifting mechanism.

[0021] In addition, the roller conveyor 1 is equipped with a front-to-back adjustable photoelectric sensor 23.

[0022] Before starting, the tire specifications are input into the control system. The control system adjusts the left and right positions of the tread cleaning component through the lateral drive mechanism according to the tire specifications, adjusts the height of the sidewall cleaning component through the lifting mechanism, and sets the stroke of the multi-jaw chuck. Then, the operator manually adjusts the position of the photoelectric sensor 23 according to the tire specifications.

[0023] During operation, roller conveyor 1 transports tires backward. When the photoelectric sensor 23 detects a tire, the control system stops roller conveyor 1, at which point the tire is positioned above the centering assembly. The control system then controls the centering assembly to operate: the first telescopic device 7 activates, its output rod extends, moving the support base 5 upward, causing multiple free rollers 14 to extend from the clearance area and insert into the tire's inner ring. Immediately afterward, the multi-jaw chuck opens, providing support for the tire's inner ring. Subsequently, the control system controls the left roller group 2 and right roller group 3 to move in opposite directions, causing the tire to rotate. Simultaneously, the tread cleaning assembly and sidewall cleaning assembly activate, cleaning the tread and sidewall using the roller brush 18. After cleaning, the left roller group 2, right roller group 3, tread cleaning assembly, and sidewall cleaning assembly stop operating. After the centering assembly resets, roller conveyor 1 restarts, transporting tires backward. Example 2
