A die-cut waste discharge device and a die-cut waste discharge method for die-cut parts with an inner frame

Abstract

The invention relates to a die-cutting waste discharge device with an inner frame die-cutting piece and a die-cutting waste discharge method. The die-cutting waste discharge device comprises a first opposite-pressing roller, first-stamping die-cutting cutters, first waste discharge rollers, a second opposite-pressing mechanism, second-stamping die-cutting cutters and second waste discharge rollers which are arranged sequentially. The first opposite-pressing roller attaches a first single face gummed protective film to a first release film; indent inner frames are punched in first stamping by the first-stamping die-cutting cutters; the first waste discharge rollers is used to take up the first single face gummed protective films attached to wastes of the inner frames after the first-stamping punching; the second opposite-pressing mechanism attaches a second single face gummed protective film to the non-release surface of the first release film, and sequentially attaches double faced adhesive tape and a second release film to the release surface of the first release film; normal inner frames are punched in second-stamping by the second-stamping die-cutting cutters; the second waste discharge rollers are used to take up the second single face gummed protective films attached to wastes of the inner frames after the second-stamping punching; and the size of each normal inner frame is bigger than the size of each indent inner frame. Compared with the prior art, the die-cutting waste discharge device has the advantages that the effect of waste discharge is good, the product has no deformation, and efficiency is high.

Description

technical field

[0001] The invention relates to a die-cutting waste discharge device and method, in particular to a die-cut waste discharge device with inner frame die-cut parts. Background technique

[0002] The die-cutting machine is used in various materials such as self-adhesive materials, protective films, electronic shielding materials, PVC, film, Mylar paper, copper and aluminum foil, double-sided adhesive tape, foam cotton, and LCD reflectors, diffusers, Die-cutting of buffer sheets, glossy films, silicone tapes, etc., are widely used in electronics, IT and automobile manufacturing industries.

[0003] figure 1 The main material of the product shown is double-sided adhesive tape with a thickness of 0.2MM, and a layer of blue release film with a thickness of 0.075MM underneath. figure 1 The middle A area is hollowed out for the inner frame, figure 1 Middle B refers to the glue area; when processing this product, because the double-sided adhesive is too thick, it wi...
