[0025] In the embodiment, when using a self-sealing coating device, the distance measuring switch 7 detects the distance between the output end of the glue needle 9 and the inside of the tire in real time, and then feeds back the data to the PLC that the automatic equipment will have, the PLC processes the data, controls the vertical movement module 2 and the horizontal movement module 3 to adjust the position, and increases the offset in real time, so as to solve the problem of poor coating effect caused by the size error of the inner wall of the tire, the switch valve 10 controls the material opening and closing of the glue needle 9, the servo motor 6 adjusts the angle of the output end of the glue needle 9, further, the coating mode of the glue needle 9 adopts spiral coating, and the position of the glue needle 9 can be adjusted to perfectly realize the coating mode, the spiral coating can ensure that the coating is uniformly distributed on the inner wall of the tire, improve the adhesion and stability of the coating, and thus enhance the puncture resistance, leakage resistance and explosion resistance of the tire.

[0026] Preferably, the vertical moving module 2 and the horizontal moving module 3 are both provided with a drag chain 11. In this way, during the operation of the vertical moving module 2 and the horizontal moving module 3, the pipelines can be stretched and retracted with the movement of the modules. If the pipelines are directly exposed, they are easy to be affected by external forces such as friction, collision and pulling, which may cause wear, breakage and damage. The drag chain 11 can wrap the pipelines inside to effectively reduce the risk of damage. In fact, protective measures for the pipelines can also be considered according to specific conditions.

[0027] Preferably, the support 1 is provided with an inclined support 12. In this way, the overall installation firmness is enhanced, and the shaking of the whole during use is further reduced, thereby ensuring the positional accuracy of the glue needle 9 during use. In fact, the length and fixing measures of the inclined support 12 can also be considered according to specific conditions.

[0028] Preferably, the vertical moving module 2 comprises a first motor 21 and a vertical moving guide rail 22. The vertical moving guide rail 22 is slidingly provided with a vertical moving sliding block 23. The vertical moving sliding block 23 is threadedly connected with a vertical lead screw connected with the output end of the first motor 21. The vertical lead screw is rotatably installed inside the vertical moving guide rail 22.

[0029] The horizontal moving module 3 comprises a second motor 31 and a horizontal moving guide rail 32. The horizontal moving guide rail 32 is slidingly provided with a horizontal moving sliding block 33. The horizontal moving sliding block 33 is threadedly connected with a horizontal lead screw connected with the output end of the second motor 31. The horizontal lead screw is rotatably installed inside the horizontal moving guide rail 32. In this way, the height position of the horizontal moving module 3 can be adjusted by controlling the first motor 21, thereby changing the height position of the output end of the glue needle 9. The horizontal position of the glue needle 9 can be changed by controlling the second motor 31, thereby achieving adaptive coating. In fact, the structures of the vertical moving module 2 and the horizontal moving module 3 can also be considered according to specific conditions.

[0030] Preferably, a heat insulation pad 13 is installed between the glue needle 9 and the glue needle mounting plate 8. In this way, heat transfer is reduced, the glue needle and surrounding components are protected, and the stability and precision of the coating process are ensured. Because the coating device generally generates high temperature during operation, and the glue needle mounting plate 8 is the support point of the glue needle 9, its stability is crucial to the coating precision. The heat insulation pad 13 can reduce the heat transfer to the glue needle mounting plate 8, prevent the displacement of the mounting position caused by the deformation of the glue needle mounting plate 8 due to thermal expansion and cold contraction, and thus ensure the stability of the coating process. In fact, the material, thickness and installation method of the heat insulation pad 13 can also be considered according to specific conditions.
