The mouth sticking mechanism comprises a rubber roll driving motor 33, a rotating cam mechanism 311, a rotating pressing mechanism 310 and a rubber roll 37, the rubber roll 37 is vertically arranged on the third rack 30, the rotating cam mechanism 311 is fixed on the third rack 30 and located below the rubber roll 37, the rubber roll 37 is intermittently lifted up through rotation of the rotating cam mechanism 311, the rubber roll driving motor 33 is arranged on one side of the rubber roll 37, the rubber roll 37 is driven to rotate and lift up and down along with the rubber roll 37, and the rotating pressing mechanism 310 is arranged above the rubber roll. The rubber roll is a rubber roll with vertical freedom degree, and after the hole is punched on the tire tube, the rubber roll is controlled by a PLC (programmable logic controller) to rotate to the right lower side at the same speed when the hole position of the tire tube is conveyed to the right lower side of the rotating pressing and pasting mechanism. Meanwhile, the protruding part of the rotary cam mechanism rotates to the uppermost part to push the rubber roller with vertical freedom degree to lift. At the moment, the three parts perform the mouth pressing action in the vertical direction, so as to realize the mouth sticking purpose. After which the mechanisms continue to move back to their original positions. After the pressing and pasting are finished, the tube flows out normally and enters a downward moving process.
The conveying system of the printing punching and sticking mouth device adopts a high-precision steel wire synchronous belt to carry, so that the tire tube cannot deviate from the center due to the deviation of the belt during conveying, and the air valve sticking mouth cannot be accurately attached to the air hole. In the winding mode of the synchronous belt, the rubber roller and the roller are successfully separated from the belt system of the conveyor belt by the sectioning (divided into a first conveyor belt and a second conveyor belt) of the conveyor belt and the avoiding mode of s, so that the rubber roller and the roller are prevented from interfering with the conveyor belt in the vertical direction, the circumference of the conveyor belt is changed, the linear speed of the conveyor belt is disordered, and the accuracy of the sticking mouth is finally influenced.

When the head of the tube is detected by the second photoelectric sensor 44, the feedback signal causes the front stage (printing perforating and nozzle sticking device) to perform printing, perforating and nozzle sticking and causes the electric heating cutter to perform cutting operation under the control of the PLC. Cutting to produce strips, the speed difference of the incoming conveyor belt 41 and the outgoing conveyor belt 43 is controlled, so that a certain gap is formed between the strips, and the operation of subsequent stations is facilitated. The gap is created so that the second photosensor 44 can detect the head position of the next bead, feed back the signal and enter the next bead cutting process. The adjustment of the length of the strip can be achieved by adjusting the relative position of the second photosensor 44 to the electroheat cutter. In normal production, the second photoelectric sensor 44 is fixed at the current position after being adjusted, namely, the detected position of the head of the tire strip is fixed with the position of the cutter during working, so that the cut tire strip has a fixed length, and the aim of fixing the length is fulfilled.
