Production system of hollow special-shaped double-faced adhesive tape die-cutting part

Abstract

The invention relates to a production system of a hollow special-shaped double faced adhesive tape die-cutting part, which is characterized in that the system comprises a pre-primary-punching laminating unit, a primary punching die-cutting unit, a pre-secondary-punching laminating unit, a secondary punching die-cutting machine (6), a secondary punching waste discharge unit, a ternary punching die-cutting unit and a die-cutting part receiving unit. After passing through the pre-primary-punching laminating unit, a low-viscosity protective film (1) and a low-viscosity bottom film (3) are respectively laminated above and below a handle release film (2); a first-stage material belt is formed after the first-stage material belt is punched by the primary punching die-cutting unit, then the first-stage material belt passes through the pre-secondary-punching laminating unit, the secondary punching die-cutting machine (6), the secondary punching waste discharge unit, the ternary punching die-cutting unit and the receiving unit to form hollow special-shaped double-faced adhesive tape die cutting part, and the product is wound. Compared with the prior art, the system has the advantages of more efficient waste discharge, reduction of the reject ratio of products and the like.

Description

technical field [0001] The invention relates to the field of processing die-cut pieces, in particular to a production system for hollow-out special-shaped double-sided adhesive die-cut pieces. Background technique [0002] Hollow special-shaped double-sided adhesive die-cut parts with a narrow outer frame, and a large part of the glue-free area inside, such as Figure 9-10 As shown, although the double-sided adhesive part is hollowed out, the handle release film is in a complete state without hollowing out. That is to say, the internal waste of the double-sided adhesive hollow pattern will not be discharged together with the handle release film. [0003] During the waste discharge process, due to the strong adhesion between the double-sided tape and the release film of the handle, when the internal waste is discharged, it will often bring up the glue of the hollowed-out special-shaped double-sided tape product, resulting in the displacement of the hollowed-out die-cut produc...
