Online film-coating embossing device for raw paper and use method for online film-coating embossing device

Abstract

The invention discloses an online film-coating embossing device for raw paper. Raw paper is wound on a paper supplying roller, an introduction roller is arranged in front of an embossing mechanism, aheating device is arranged between the introduction roller and the embossing mechanism, a film coating machine is arranged just above the embossing mechanism, a cooling roller is arranged behind the embossing mechanism, paper comes out from the cooling roller and is wound and collected by a paper winding roller, and auxiliary rollers are arranged at the left and right of the embossing mechanism. Ause method of the online film-coating embossing device comprises the steps: the raw paper is wound on the paper supplying roller, is unwound through the paper supplying roller and is heated by the heating device, then, the heated raw paper is introduced into the embossing mechanism, the film coating machine carries out film coating on the raw paper, meanwhile, the embossing mechanism carries outdouble-sided thermal embossing on the raw paper, and then, the paper is cooled by the cooling roller and finally is wound and collected by the paper winding roller. According to the online film-coating embossing device for the raw paper, the coating quality is good, the coating is thin, the cost is low, the patterns are clear and uniform, the paper sheets are smooth, and the use performance of embossed release paper is improved. According to the use method for the online film-coating embossing device for the raw paper, the efficiency is increased, the coating quality is good, and the pattern forming is clear and uniform.

Description

technical field [0001] The invention relates to the technical field of paper, in particular to an online laminating and embossing device for base paper and a method for using the same. Background technique [0002] Release paper is a special anti-sticking paper used for artificial leather. Its coating generally has a concave-convex pattern structure. It is widely used in artificial leather and synthetic leather. The coating is formed by laminating and then embossed. [0003] The particularity of the use of release paper must meet the following performance requirements. The base paper needs to maintain a certain thickness and uniform pattern. After repeated use, the embossing of the release paper must still maintain a uniform state. The number of times the release paper is reused is not less than 25 times, and the release paper must have sufficient strength in multiple uses. The release paper has high requirements for tear strength. When the release paper is in use in the w...

AI Technical Summary

Problems solved by technology

[0005] 1. The base paper is coated separately first, and after it is cooled and solidified, the coated base paper is embossed on one side by an embossing roller. There are many production processes and the production efficiency is reduced; when the base paper is coated, the coating is decomposed by heat. When embossing alone, the coating is decomposed by heat again, and the coating is decomposed by heat twice, which will cause the quality of the coating to decline, affect the clarity of the embossing, and reduce the performance of the final embossed release paper

[0006] 2. The patterns embossed by the embossing roller on one side of the base paper are not clear enough, and the depth is uneven;

[0010] 1. Coating and embossing are carried out separately, and there are many production processes, which reduces production efficiency;

[0011] 2. When the base paper is coated, the coating is decomposed by heat, and the coating is decomposed by heat again when embossing alone. The thermal decomposition of the coating twice will cause the quality of the coating to decline, affect the clarity of the embossing, and reduce the final embossing. The performance of grain release paper

[0012] 3. Embossing on one side of the base paper makes the pattern of the extruded base paper difficult to form, and the pattern is not clear and uneven;
