Description

Technical Field

[0001] The utility model relates to the technical field of die cutting machines, in particular to a combined knife die for a die cutting machine. Background Art

[0002] Traditional flat cutting is called flat knife die cutting, while rolling cutting is also called round knife die cutting. Round knife die cutting is driven by a motor to rotate the die roller. The die knife is set on the outer wall in the middle of the die roller. The motor drives the die roller to rotate, and the die roller drives the die knife to rotate. When the rotation of the die roller is pressed together with the impression roller, the die knife contacts the material and cuts the material. It adopts the line contact principle of circle pressing circle.

[0003] According to a combined die-cutting die with publication number CN218947912U, the connection between the connecting flange and the connecting flange can be disconnected by disassembling bolt 2, so that the connecting flange and the die-cutting roller can be taken out from between the connecting flanges, and then a new die-cutting roller can be replaced. This method can reduce the length of the die-cutting roller, and form a die-cutting die in a combined use mode, which has the technical effects of reducing costs, not requiring disassembly of the whole, and convenient disassembly and assembly. However, during the die-cutting process, because the external thread teeth on the connecting rod are exposed to the outside, the generated debris will fall onto the external thread teeth on the outside of the connecting rod, affecting the use of the external thread teeth.
