The supporting reinforcing ribs are connected with two opposite side edges of each group of die cutting edges in a bridging mode, and extend along the rolling direction of the cutter shaft.

The scheme is further that the adjacent distance between the multiple groups of die cutting edges is not less than 10 mm.

According to the scheme, the punching blades are integrally manufactured on the rolling peripheral surface of the cutter shaft and are arranged on the inner side and the outer side of the frame shape of each group of die cutting blades, through holes are formed in the punching blades and are communicated with a cavity in the cutter shaft, and the cavity forms a waste discharge system.

By adopting the structure, the utility model increases the structural strength of the die cutting edge by supporting the reinforcing ribs, ensures the die cutting processing, reduces the condition of knife breakage or blade deformation, has long service life and improves the production efficiency and quality; and the cavity is arranged in the cutter shaft, so that the waste materials cut by the punching blade directly fall into the cavity in the cutter shaft, the waste materials are removed, the waste materials can be prevented from scattering to pollute the environment, the cavity forms a waste discharge system, waste can be discharged in modes of suction and the like, the structure is simple, the use is convenient, and the production efficiency is favorably improved.
