AI Technical Summary

Technical Problem

In existing die-cutting technologies, waste removal is difficult, especially for thick materials and double-sided adhesive products, leading to material waste and increased labor costs. Furthermore, conventional waste removal methods are complex and have high equipment costs.

Method used

The die-cutting waste removal device includes a first feeding mechanism, a die-cutting mechanism, an upward waste removal mechanism, and a winding mechanism. It uses ejector pins to directly remove waste material after die-cutting, and the waste material falls into the trash can. Combined with specific blade edge die-cutting of the outer and inner frames, it saves auxiliary materials and improves waste removal efficiency.

Benefits of technology

It enables direct waste removal, saves auxiliary materials, reduces waste removal costs, improves waste removal efficiency, and solves the problem of difficult waste removal for thick materials and double-sided adhesive products.

Abstract

The invention relates to a die cutting waste discharge device and a die cutting waste discharge method.The die cutting waste discharge device comprises a first feeding mechanism, a die cutting mechanism, a lifting waste discharge mechanism and a winding mechanism which are sequentially arranged in the advancing direction of a material belt, and the first feeding mechanism is used for inputting the material belt; the die cutting mechanism comprises an ejector pin, a garbage can, a lower die base, an upper die base and cutter points, the cutter points with different die cutting depths are arranged below the upper die base, the ejector pin is arranged on the side, away from the first feeding mechanism, of the upper die base, the garbage can is arranged below the lower die base, and the cutter points are used for die cutting of material belts. The material belt subjected to die cutting is conveyed to an ejector pin to eject waste materials, and the waste materials fall into a garbage can; the lifting waste discharge mechanism is used for collecting and discharging outer frame waste after material belt die cutting; and the winding mechanism is used for winding the treated material belt to obtain a product. Compared with the prior art, waste is discharged after die cutting, auxiliary materials are saved, the waste discharging efficiency is improved, and the waste discharging cost is reduced.
