Technical Field

The invention relates to the technical field of die cutting equipment manufacturing and die cutting forming processing, in particular to a same-die multi-section asynchronous die cutting device.

Background

The conventional die cutting mode in the existing die cutting processing technology is that a substrate is attached to a main material, or a release film is attached to the main material, then die cutting or multiple small hole sleeve position die cutting is carried out through a cutting die, redundant waste materials are discharged, and a product area needing to be reserved is obtained, namely a processed finished product. In the existing die cutting processing technology, the typesetting clearance of die cutting products is large, and the utilization rate of main materials is low. And thus asynchronous cutting machines have been developed.
