Description

Technical Field

[0001] The utility model relates to the field of die cutting, in particular to a die cutting mechanism. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting of some corresponding non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc.; it is necessary to cut the initial material strip into a certain shape and cut marks according to the actual situation. The die-cutting machine applies pressure to the material strip through the knife die to cut the required cut marks on the material strip.

[0003] The last process of the die-cutting machine is waste removal, which removes the waste from the cut marks after die-cutting. The traditional method is air-blowing waste removal, which uses the impact of gas to remove the waste from the cut marks, and the blown waste will fall into the collection frame below. When the gas impact force is too large, the high-speed airflow can easily cause the film material at the edge of the waste to be compressed and damaged. At the same time, the tiny waste blown out is difficult to accurately enter the collection frame under the influence of the high-speed airflow, affecting the work efficiency of subsequent recycling.

[0004] When the process edge needs to be removed, the process edge separated from the material strip will hang freely and fall into the collection frame. When the process edge and waste materials such as debris are accumulated in the collection frame together, the gaps between the process edges will occupy a certain space because the process edge is in the shape of a strip, which leads to the need to replace the collection frame in time.
