[0023] With such a design, when in use, the tire is placed inside the arc-shaped groove 5 in the workbench 3, and then the mounting frame 8 is pushed so that the electric push rod 9 at the end of the mounting frame 8 enters the interior of the tire, and then the square tube 10 is driven downward by the electric push rod 9, so that the rubber roller 14 on the square tube 10 abuts against the inner wall of the tire, and then the rubber in the hot melt box 4 is transported to the interior of the square tube 10 through the pump body 12, and the corresponding roller 6 is driven to rotate by the driving device 7, and the tire is driven to rotate at a low speed by the roller 6, so that the rubber sprayed from the nozzle 11 on the square tube 10 is smeared on the inner wall of the tire, and the rubber is evenly spread by the rubber roller 14 to ensure the uniformity of the rubber when smearing, thereby completing the gluing operation.

[0024] The two side frames 13 have the same structure. A chute 15 is formed on the side frame 13. A slider 16 is slidably arranged in the chute 15. The slider 16 is rotatably arranged with the rubber-distributing roller 14. The top of the slider 16 is fixed to the inner top wall of the chute 15 by a telescopic spring 17.
