[0031] In summary: when the jointing machine for processing quick-mount tires is used, the position of the driving wheel 10 is adjusted by the rotating telescopic structure, so that the tire piece conveyed by the conveying structure can contact the top of the drum or the semi-finished tire, and the guide roller 8 limits the tire piece under the action of the translational lifting structure, so that when the drum rotates, the tire piece can be wound on the drum. In the process of the tire piece being wound on the semi-finished tire, the pressing roller 2 5 and the pressing roller 3 26 press the tire piece, so that two adjacent tire pieces can be pressed. When the joint part needs to be pressed, the guide roller 8 is reset under the action of the translation lifting structure, the moving wheel 10 is reset under the action of the rotation telescopic structure, and the visual sensor 7 takes a picture of the joint part. The controller in the joint machine controls the servo motor 6 to rotate according to the photographed image, and the servo motor 6 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the pressing roller 21 to rotate until as many pressing rollers 21 as possible move to the top of the joint part, and the hydraulic telescopic rod 20 drives the pressing roller 21 to move downward until the pressing roller 21 contacts the joint part, and the pressing roller 21 can press the joint part. During the pressing process, the electric telescopic rod 22 drives the pressing roller 21 to move to expand the range of the joint part being pressed. If there is an area of ​​the joint part that is not pressed, the drum drives the joint part to rotate and changes the position of the joint part, so that the above steps are repeated until the joint part is pressed.
