Foam die cutting piece manufacturing method capable of preventing handle film from adhering to material belt

Abstract

The invention relates to a foam die cutting piece manufacturing method capable of preventing a handle film from being adhered to a material belt. The method comprises the following steps: (1) adhering a first-stage material belt; (2) primary punching die cutting and waste discharging; (3) attaching a second-stage material belt; (4) secondary punching and waste discharging: performing secondary punching and cutting on the second-stage material belt in a secondary punching and cutting machine, punching a second release film (7) into a next anti-sticking protective film (71) which is adhered to the lower part of the handle film (5), and discharging secondary punching and waste materials; a foam pad (91) enabling an anti-sticking protective film (71) to be attached to the lower portion of the handle film (5) is arranged on the secondary punching die cutting machine. And (5) laminating and rolling the foam die cutting piece finished product. Compared with the prior art, under the condition that only two-step punching is needed, the stripping reject ratio of the product is reduced from about 50% to nearly 0%, and compared with some three-step die cutting, the productivity is improved by 1.5 times.

Description

technical field [0001] The invention relates to the field of die-cutting production, in particular to a method for making a foam die-cutting that prevents a handle film from sticking to a material belt. Background technique [0002] With the development of technology, the use of automation is increasing. For some types of foam products, the foam has a single-sided adhesive, and a handle film is required on the non-adhesive side of the foam to make a handle, which is convenient to use. like Figure 11-12 , is the top view and perspective view of the existing product. [0003] Since the handle film on the foam is a film with glue on one side, the handle position of the handle film, that is, the position without shadow, is larger in size, and the handle position is easy to stick to the tape film, resulting in that it cannot be peeled off when the product is peeled off. . Contents of the invention [0004] The object of the present invention is to provide a method for makin...
