The first negative pressure source and the second negative pressure source can share a vacuum pump. When the paper 101 is placed on the feeding platform 12, the second negative pressure source adsorbs and fixes the paper 101 through the second vacuum hole 122. The first telescopic driving assembly 14 includes a first cylinder and a connecting block. The cylinder drives the connecting block to move, and the connecting block drives the feeding platform 12 to move in the horizontal direction. The telescopic pressing assembly 16 includes a second cylinder 162 and a pressing roller 164. The second cylinder 162 pushes the pressing roller 164 to move in an oblique downward direction.

The support plate 36 is arranged in the horizontal direction. When the first pressing roller 34 moves to the position of the first vacuum hole 242 under the push of the first telescopic assembly 32, the support plate 36 is butt-connected between the feeding platform 12 and the pipe rolling die 24. The support plate 36 can support the paper 101, so that when the paper 101 is conveyed to the position of the first vacuum hole 242, the position of the paper 101 is not likely to change, which is convenient for the paper 101 to smoothly and accurately enter the working station of the pipe rolling die 24.

[0056] Please refer to Figures 5 to 7 , in one embodiment, the second pressing mechanism 40 includes at least one first pressing roller unit 42 and at least one second pressing roller unit 44.

Each second pressing roller 424 is located at one end of the pipe rolling die 24, and each third pressing roller 444 is located at the other end of the pipe rolling die 24. The second pressing roller 424 and the third pressing roller 444 are rotatably arranged and are respectively parallel to the pipe rolling die 24. Specifically, the first pressing roller units 42 and the second pressing roller units 44 are respectively multiple. Since the second pressing roller 424 and the third pressing roller 444 are arranged in a staggered manner in sequence along the circumferential direction of the pipe rolling die 24, each second pressing roller 424 is located at one end of the pipe rolling die 24, and each third pressing roller 444 is located at the other end of the pipe rolling die 24, it can avoid interference between the first pressing roller 34 and the second pressing roller 424, and can also ensure that during the pipe rolling process, the paper 101 can always be tightly attached to the pipe rolling die 24, avoiding phenomena such as the paper 101 warping.

When the lengths of the first pressing roller 34, the fourth pressing roller 464 and the tube rolling die 24 are respectively equal, it can ensure that the paper 101 is completely adhered to the tube rolling die 24. When the sum of the lengths of one second pressing roller 424 and one third pressing roller 444 is equal to the length of the tube rolling die 24, it can avoid interference between the first pressing roller 34 and the second pressing roller 424, and can also ensure that during the tube rolling process, the paper 101 can always be adhered to the tube rolling die 24, avoiding phenomena such as the paper 101 warping.
