The invention is further described in detail below in connection with the detailed description.

The tire winding production line is shown in fig. 5, and comprises an extruder, a molding press, a cooler, a conveyor and a winding machine, wherein the extruder extrudes rubber material and sends the rubber material into the molding press, the molding press rolls the rubber material to form rubber strips, then the rubber strips are conveyed to the cooler to be cooled, and the cooled rubber strips are conveyed to the winding machine through the conveyor to wind tire blanks. The molding press is shown in fig. 1, and comprises a machine body 10, wherein the machine body 10 is provided with a pair of

molding rollers

1 and 2, the molding rollers 1 are provided with two parallel

annular molding grooves

11 and 12 with different sizes, as shown in fig. 2, the

grooves

11 and 12 are wider than the groove bottoms, and the groove widths of the molding grooves 11 are larger than the groove widths of the corresponding parts of the molding grooves 12. The

profiling rolls

1, 2 are arranged one above the other, with the profiling roll 1 being on top. The machine body 10 is also provided with a first adhesive tape conveying roller 3 and a second adhesive tape conveying roller 4. In this example, the

profiling rollers

1, 2 and the first adhesive tape conveying roller 3 are driven together by a driving motor 7 shown in fig. 4, specifically, a driving gear 71 is connected to the output shaft of the driving motor 7 in a transmission manner, driven

gears

73, 72 and 74 are respectively arranged at the left ends of the

profiling rollers

1, 2 and the first adhesive tape conveying roller 3, the driving gears 71 are respectively connected with the driven

gears

72 and 74 in a transmission manner, the driven gears 72 are connected with the driven gears 73 in a transmission manner, and thus the driving motor 7 can drive the
