Circular knife extracting die cutting waste

Abstract

The invention belongs to the technical field of a die-cutting machine, and discloses a circular knife extracting die cutting waste. The circular knife extracting the die cutting waste comprises a body and roll shafts, wherein the roll shafts are arranged on the two ends in the lengthwise extending direction of the body in a protrudingly extending mode; the body and the roll shafts are internally provided with cavities in communication with each other; the surface of the body is provided with multiple through holes; the through holes are communicated with the cavities; the surface of the body is also wrapped with at least one loop of cohesive layer; the cohesive layers and the through holes are distributed at intervals. According to the circular knife extracting the die cutting waste, the end portion of the circular knife body can be connected with an air compressor, so that the die cutting waste can be extracted effectively by the combined action of high speed airflow and the cohesive layers, and a structure of an integrate circular-bed cylinder die-cutting machine is simplified.

Description

technical field [0001] The invention relates to the technical field of die-cutting machines, in particular to a circular knife for extracting die-cutting waste. Background technique [0002] Die-cut products generally consist of a release liner, a protective layer and an adhesive layer in between. Die-cut products are widely used in automobile manufacturing, electronics industry, especially flat panel display, mobile digital industry. According to the shape of the internal frame of the electronic product, use a die-cutting knife with a specific shape to stamp or roll to die-cut a specific shape. Then peel off the protective layer on the surface, stick the die-cut product on the inner frame of the electronic product, then peel off the release paper, and finally fix the inner frame and outer shell of the electronic product firmly with the stickiness of the adhesive layer. This assembling method does not need to use screw connection to connect the shell and the internal frame...

AI Technical Summary

Problems solved by technology

However, when the rotary die-cutting machine in the prior art extracts the die-cutting waste, it often needs to extract the die-cutting waste through multiple sets of waste extraction circular knives, so the circular pressing circular die-cutting machine used to extract the die-cutting waste in the prior art Die cutters are expensive to manufacture
