[0030] like Figure 1-5 As shown, the tire processing bracket 2 is installed on the tire L-shaped processing table 1. The tire L-shaped processing table 1 and the tire processing bracket 2 are equipped with a tire winding structure, a hot melt forming structure, a grinding structure and an automated handling structure.

[0031] In some specific embodiments of the present invention, the tire winding structure includes: axle changing disc 3, axle changing stepper motor 4, concave axle changing ring block 5, a pair of collecting shaft tubes 6, several convex extension and telescopic blocks 7, several arc extension blocks 8, a pair of collecting gearboxes 9, a pair of collecting drive motors 10, hydraulic tank 11, liquid pump 12, diversion valve pipe 13, several concave outer limit blocks 14, several convex outer limit telescopic blocks 15, several arc extrusion blocks 16, and several sealing strips;

[0032] In some specific embodiments of the present invention, a drive groove is provided on the L-shaped tire processing table 1, a concave shaft changing ring block 5 is installed inside the drive groove, a shaft changing disc 3 is movably inserted into the inner side of the concave shaft changing ring block 5, a shaft changing stepper motor 4 is installed inside the drive groove, and the drive end of the shaft changing stepper motor 4 is connected to the shaft changing disc 3, a pair of collecting shaft tubes 6 are inserted into the shaft changing disc 3 through bearings, a pair of collecting gearboxes 9 are installed on the shaft changing disc 3, and the pair of collecting gearboxes 9 are respectively fitted onto the pair of collecting shaft tubes 6, the drive ends of a pair of collecting drive motors 10 are respectively connected to the pair of collecting gearboxes 9, and a plurality of convex telescopic holes are respectively provided on the pair of collecting shaft tubes 6, and a plurality of convex expansion telescopic blocks 7 are movably inserted into the plurality of convex expansion telescopic blocks 7. Inside the constriction hole, several arc-shaped expansion blocks 8 are respectively installed on several convex expansion and telescopic blocks 7, several concave outer limit blocks 14 are evenly installed on the shaft changing disc 3, several convex outer limit telescopic blocks 15 are respectively movably inserted into the inside of several concave outer limit blocks 14, several arc-shaped extrusion blocks 16 are respectively installed on several convex outer limit telescopic blocks 15, several sealing strips are respectively installed on several convex outer limit telescopic blocks 15 and several convex expansion and telescopic blocks 7, hydraulic tank 11 is installed inside the drive groove, liquid pump 12 is installed on hydraulic tank 11, diversion valve pipe 13 is installed on liquid pump 12, and diversion valve pipe 13 is connected to several concave outer limit blocks 14 and a pair of collection shaft pipes 6.

[0033] In use, the liquid inside the hydraulic tank 11 is drawn by the pump 12 to the inside of several concave outer limiting blocks 14 and a pair of collecting shaft tubes 6. The hydraulic pressure inside the collecting shaft tubes 6 causes several convex expansion and contraction blocks 7 to expand and contract inside the collecting shaft tubes 6. The collecting drive motor 10 on the shaft-changing disc 3 rotates, driving the collecting gearbox 9 on its drive end to rotate. The collecting gearbox 9 then rotates the collecting shaft tubes 6, first collecting the raw material on the collecting shaft tubes 6. Hydraulic pressure is then applied to the convex outer limiting expansion blocks 15 inside the concave outer limiting blocks 14. The expansion and support of the convex expansion and contraction blocks 7 inside the collecting shaft tubes 6, along with the expansion of the concave outer limiting blocks 14, further contribute to the process. The inner convex outer limiting telescopic block 15 performs extrusion limiting. Through the cooperation of the arc expansion block 8 on the convex expansion telescopic block 7 and the arc extrusion block 16 on the convex outer limiting telescopic block 15, extrusion collection and expansion shaping within a certain range are achieved. Through internal expansion and external extrusion limiting, the shaping effect is achieved. The cutter on the shaft changing disc 3 cuts the raw material on the collection shaft tube 6. The shaft changing stepper motor 4 runs, driving the shaft changing disc 3 on the drive end of the shaft changing stepper motor 4 to rotate, thereby changing the position of a pair of collection shaft tubes 6. This facilitates the automated handling structure to handle the expanded raw material. The automated handling structure handles the raw material to the hot melt forming structure, where the raw material is hot melt formed.

Several hot-melt arc blocks 21 are respectively installed on several hot-melt convex blocks 20. A pair of concave hot-melt limiting blocks 22 are horizontally and parallelly installed opposite each other on the tire L-shaped processing table 1.

A pair of hot-melt limiting rollers 26 are respectively provided with cross-shaped telescopic grooves.

These convex hot-melt limiting blocks 23 extend and retract along the inner sides of a pair of concave hot-melt limiting blocks 22, which in turn drive a pair of hot-melt limiting rollers 26. Two pairs of current regulators 31 then control the two pairs of electromagnet blocks 30. The system controls the magnetic expansion of the magnetic ring block 29 by two pairs of electromagnet blocks 30. The magnetic ring block 29 drives the two pairs of ring telescopic blocks 28 on it, which in turn drives several convex telescopic rods 27 on it. These convex telescopic rods 27 extend and retract horizontally inside several cross-shaped telescopic grooves. The convex telescopic rods 27 heat-melt the edges and corners of the raw material into a cylindrical shape, and simultaneously heat-melt the bent parts. The operation of the heat-melting drive machine 19 drives the heat-melting gearbox 18 on the drive end of the heat-melting drive machine 19. The heat-melting gearbox 18 drives the heat-melting limiting shaft tube 17 inside it.
