Production system for soft foam die-cutting piece with large foaming holes

Abstract

The invention relates to a production system for a soft foam die-cutting piece with large foaming holes. The system comprises an auxiliary protective film discharging roller (11), a handle release film discharging roller (12), a first pre-punching attaching unit, a first punching die-cutting machine (3), a second pre-punching attaching unit, a second punching die-cutting machine (5), a finished product attaching unit and a die-cutting piece collecting roller (71). Compared with the prior art, the production system has the advantages that poor stripping is prevented, and the reject ratio of products can be reduced to almost zero.

Description

technical field [0001] The invention relates to the field of processing foam die-cut parts, in particular to a production system for soft foam die-cut parts with large foam holes. Background technique [0002] Foam is foamed, so there are generally pinhole-type holes in the foam, which is more obvious on some softer foams. Generally, a layer of double-sided tape needs to be pasted on the foam, and a layer of double-sided tape can also be pasted on both sides of the foam. [0003] After the product is formed, the second double-sided adhesive tape is to be pasted on the entire material tape, such as figure 1 , due to the pinholes on the foam, there is a drop in the glue attached to the foam, and there are often poor peeling between the product and the tape, such as figure 2 , that is, when the product is peeled off, the product will stick to the tape. Because the foam itself is relatively expensive, the production process of similar products is also relatively complicated,...

AI Technical Summary

Problems solved by technology

[0003] After the product is formed, the second double-sided adhesive tape is to be pasted on the entire material tape, such as figure 1 , due to the pinholes on the foam, there is a drop in the glue attached to the foam, and there are often poor peeling between the product and the tape, such as figure 2 , that is, when peeling the product, the product will stick to the tape

Because the foam itself is relatively expensive, the production process of similar products is also relatively complicated, and the price of the entire product is relatively high. Once there is a poor peeling, it must be scrapped and reworked, resulting in a waste of resources and an increase in cost.
