The through hole is provided on the central axis of the cutter roller, and the rotating shaft is sleeved in the through hole of the cutter roller. The rotating shaft is connected to the surface of the through hole through a bearing or a lubricant." When in use, the roller cutter die of the composite roller cutter machine of the utility model increases the buffering capacity by providing a filling layer on the inner side of the cutter roller, so that the positioning stability is not affected when the pressing and cutting force is increased. Qualitative, and improve the quality of pressing or embossing. During operation, the filling layer can effectively relieve the pressure applied to the material. When the material is thick, the pressure is high. When the material is consumed to a thinner layer after a period of operation, the elastic force of the filling layer replenishes the pressure loss, and the buffering capacity is used to reduce the occurrence of bending. However, the hob die of the composite hob machine needs to cut hard objects, such as metal, etc. However, since such materials are hard, the damage to the cutter body is greater, and replacing the entire cutter body is more wasteful. In addition, during the cutting process, if the cutting is blocked, the motor is likely to burn out, which leads to the occurrence of safety accidents.
