When the auxiliary transmission structure works, the adjusting screw 24 is screwed out of the threaded hole to be in contact with the pressing plate 23, and when the length of the adjusting screw screwed out of the threaded hole is increased, the pressure of the transmission roller 2 in the auxiliary transmission structure on the die roller 1 and the anvil roller 4 is increased; when the length of the adjusting screw 24 screwed out of the threaded hole becomes smaller, the pressure of the driving roller 2 on the die roller 1 and the anvil roller 4 becomes smaller in the auxiliary driving structure. Through the process, the pressure of the driving roller in the auxiliary driving structure on the die roller 1 and the anvil roller 4 can be adjusted by adjusting the length of the screw 24 screwed out of the threaded hole. Therefore, the contact pressure and the distance between the auxiliary transmission structure and the die roller and between the auxiliary transmission structure and the anvil roller can be adjusted.
