The empty space here is reserved for the conveying assembly, and the conveying assembly includes a feeding motor 9, a third bracket 10, an active roller 11 and a driven roller 12; the third bracket 10 is installed at the empty space between the first material conveying bottom plate 7 and the second material conveying bottom plate 8, the active roller 11 is rotatably installed at the lower part of the third bracket 10, and the driven roller 12 is rotatably installed at the upper part of the third bracket 10; the feeding motor 9 is installed at the lower part of the third bracket 10 and the feeding motor 9 is connected to the active roller 11 in transmission, and the active roller 11 is driven by the feeding motor 9 to rotate, thereby driving the rubber film between the active roller 11 and the driven roller 12 to move along the direction where the second material conveying bottom plate 8 is located. The gap between the active roller 11 and the driven roller 12 is located at the same horizontal plane as the upper surface of the first material conveying bottom plate 7. Specifically, the feeding motor 9 is connected to the active roller 11 through a synchronous belt and a synchronous wheel. The gap width between the active roller 11 and the driven roller 12 is not greater than the thickness of the film, and the film forms rolling friction with the active roller 11 without slipping, while the synchronous belt and the synchronous wheel ensure the accuracy of the film movement without displacement error. The conveying assembly is used as the power to drive the film to move, and is set in an empty position. It does not affect the movement of the film on the first material conveying bottom plate 7 and the second material conveying bottom plate 8, and can ensure that the film is not misaligned. The column 5 of the unloading assembly is installed beside the first material conveying bottom plate 7, the unloading motor 6 is installed at the upper end of the column 5, the storage roll 4 is coaxially fixed with the output shaft of the unloading motor 6, and the storage roll 4 is located directly above the first material conveying bottom plate 7.

Specifically, the tensioning assembly includes a fourth bracket 22 and a tensioning roller 23; the fourth bracket 22 is installed above the first material conveying bottom plate 7, and a plurality of tensioning rollers 23 are provided, and all tensioning rollers 23 are rotatably installed on the fourth bracket 22. The film passes through all the tensioning rollers 23 in turn and then passes through the gap between the first material conveying bottom plate 7 and the feeding positive pressure plate 21. The tensioning assembly ensures the tensioning force of the film conveying, does not relax, and does not affect the conveying accuracy of the film.

[0025] In addition, the first material conveying bottom plate 7 and the second material conveying bottom plate 8 in this embodiment are provided with positioning holes 24 adapted to the film. Whenever the punching die 17 descends to the lowest point, the positioning holes 24 must be penetrated to ensure that two strip-shaped through holes are formed on the film.
