A V-shaped mouth peeling die-cutting process

Abstract

The invention discloses a V-shaped opening peeling and die cutting process. A raw material comprises bottom paper, a low-viscosity film and foam. A die cutting method includes the steps: correspondingly compounding the bottom paper and the low-viscosity film, and enabling the release surface of the bottom paper to be upward; performing die cutting on compounded bottom paper by the aid of a V-shaped slitting knife die, and performing downward semi-cutting to reach the low-viscosity film to obtain an initial V-shaped film; compounding the initial V-shaped film and the foam, compounding the foamon the release surface of the bottom paper, performing die cutting on the foam by the aid of a forming die cutting jig, and performing downward semi-cutting to reach the bottom paper; discharging outer frame waste of the foam, adding separation paper on the upper surface of the foam, and winding the foam to obtain a finished product. According to the V-shaped opening peeling and die cutting process, initial downward die-cutting of a V-shaped opening is implemented, the process solves the problem that a product cannot be peeled from the bottom paper, the product cannot be affected by weather, requirements of the die cutting process for release force are low, excessive resources for researching real matching between the bottom paper and glue are omitted, development resources are saved, anda development period is shortened.

Description

technical field [0001] The invention belongs to the field of die-cutting technology, in particular to a V-shaped mouth stripping die-cutting technology. Background technique [0002] In the current die-cutting industry, foam + glue products are the most widely used and widely used. The product is characterized by strong adhesiveness of the main material and soft foam material, so such products are prone to reverse release or retention. Backing paper problems, production, storage, and transportation process are difficult to guarantee the yield. [0003] At present, in the die-cutting industry, 90% of the abnormalities in the production of foam + rubber products are caused by anti-release and backing paper. These two problems are also the most complained about by customers; especially the problem of backing paper is such a product. It is difficult to completely eradicate the "cancer" of this kind of product, because the raw material foam and glue of this kind of product are g...

[0002] In the current die-cutting industry, foam + glue products are the most widely used and widely used. The product is characterized by strong adhesiveness of the main material and soft foam material, so such products are prone to reverse release or retention. Backing paper problem, production, storage, and transportation process are difficult to guarantee the yield

[0003] At present, in the die-cutting industry, 90% of the abnormalities in the production of foam + rubber products are caused by anti-release and backing paper. These two problems are also the most complained about by customers; especially the problem of backing paper is such a product. It is difficult to completely eradicate the "cancer" of this kind of product, because the raw material foam and glue of this kind of product are greatly affected by the external climate, and the weather resistance is poor, such as temperature, humidity, etc., which makes it difficult to match the backing paper. In winter, the backing paper may no longer be matched, so it is difficult to control the production process, the yield rate of the process is very low, and the production cost increases; because the problem of the backing paper cannot be well solved, it is necessary to strengthen the storage environment control and Transportation environment control increases cost input

The increase in production cost, storage cost and transportation cost has greatly increased the cost and reduced the market competitiveness of the product
