Description

Technical Field

[0001] The utility model relates to the technical field related to release paper processing, in particular to a release paper laminating device capable of automatically adjusting tightness. Background Art

[0002] Release paper is a kind of anti-stick paper that prevents prepreg from sticking and protects prepreg from contamination. Release paper is made of paper coated with anti-stick material. Its model is differentiated according to the material, thickness, elongation, single and double sides. During the production process of release paper, a laminating device is required to achieve the compression connection of the double paper layers.

[0003] After massive searches, it was found that the prior art publication number is CN210062324U, which discloses an automatic laminating device for release paper, including a processing box, a winding roller is arranged inside the processing box, a release paper body is arranged on the winding roller, the release paper body is introduced into the laminating component through a first guide roller, a conveying roller is arranged below the winding roller, a sticky workpiece is arranged on the conveying roller, the sticky workpiece is introduced into the laminating component through the conveying roller, and a rolling mechanism is arranged on the right side of the laminating component. The utility model is an automatic laminating device for release paper, which achieves dust removal of the release paper by arranging a dust removal roller, a positioning plate and a lifting groove, etc., and positioning and guiding the release paper and the sticky workpiece during introduction to improve the laminating effect, thereby solving the problem that most of the current release paper laminating devices do not have a positioning function, and the positions of the release paper and the sticky workpiece are often offset, resulting in poor laminating effect.

[0004] To summarize, when the existing laminating device is laminating the release paper, the upper and lower laminating rollers are generally driven up and down by a driving mechanism such as a cylinder or an electric push rod to achieve the laminating process of the release paper.
