Release paper embossing device and embossing method thereof

Abstract

The invention discloses a release paper embossing device. Release paper is arranged on a paper supply roller, a guide-in roller is arranged in front of an embossing mechanism, the embossing mechanismcarries out dual-face embossing on transmitted release paper, a heating device is arranged between the guide-in roller and the embossing mechanism, a transmission roller drives the embossing mechanismand an auxiliary roller, a cooling roller is arranged behind the embossing mechanism, and the release paper is guided out of the cooling roller and is wound and collected by a paper receiving roller.An embossing method of the release paper embossing device comprises the steps that the release paper is wound on the paper supply roller, the release paper is unwound through the paper supply roller,the heating device carries out heating, the paper is guided into the embossing mechanism to be embossed, the cooling roller caries out rolling, and finally, the paper is wound and collected by the paper receiving roller. According to the release paper embossing device, the release layer is subject to dual-face embossing, a coating layer is thin, the cost is reduced, figures are easily formed, thefigures are clear and uniform, and paper is flat; and according to the embossing method of the release paper embossing device, the release paper is subject to dual-face embossing, figure forming of the release paper is good, the figures are clear and uniform, a certain strength is kept for the paper, and the repeated use frequency is high.

Description

technical field [0001] The invention relates to the technical field of release paper, in particular to a release paper embossing device and an embossing method thereof. 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. [0003] The particularity of the use of release paper must meet the following performance requirements. The release 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 width direction When there is a tear, it must be able to withstand a ...
