[0037] In summary: by placing the unwinding roller 26 between the two fixed plates 2, the block 25 located on the rear side is inserted into the inner cavity of the square groove 27, and then the hand wheel is rotated to rotate the threaded rod 22 fixed on the hand wheel, and the fixed plate 2 connected to the threaded rod 22 is rotated to slide on the top of the base 1, so that the block 25 located on the front side is inserted into the inner cavity of the adjacent square groove 27, so as to facilitate the installation of the unwinding roller 26, and place one end of the raw material wound on the unwinding roller 26 on the top of the lower mold body 7, and start the electric telescopic rod 4 through the control panel 12, and the electric telescopic rod 4 moves downward, and through the connecting block 5 fixed at the end of the electric telescopic rod 4, the upper mold body 6 fixed on the connecting block 5 is in contact with the lower mold body 7, so as to pre-punch the raw material, and when the connecting block 5 moves upward, it can be connected by the cross bar 81 fixed on the connecting block 5, so that the upper mold body 6 fixed on the cross bar 81 can be connected to the lower mold body 7. The transmission rack plate 82 on the rod 81 moves upward, thereby rotating the rotating gear 83 meshing therewith, and during the rotation process, the fixed block 833 fixed on the circular block 832, and the limit telescopic rod A834 and the spring A8341 make the pawl 835 tightly contact with the ratchet groove 831. When the rotating gear 83 rotates, the circular block 832 can be rotated, and then the connecting rod 23 fixed on the circular block 832 can be rotated. Under the action of the disc 24 fixed at the end of the connecting rod 23 and the block 25 fixed on the disc 24, the unwinding roller 26 can be rotated to unwind the raw material wound on the unwinding roller 26.
