Pressure-sensitive adhesive laminating device and laminating method

Abstract

The invention discloses a pressure-sensitive adhesive laminating device which comprises a machine table, a first substrate for supporting to-be-laminated pressure-sensitive adhesive, a laminating steel roller arranged above the machine table and used for providing a pressing force for laminating the pressure-sensitive adhesive, and a laminating rubber roller fixed relative to the machine table. The center line of a roller shaft of the laminating rubber roller is parallel to the center line of a roller shaft of the laminating steel roller, and the laminating rubber roller and the laminating steel roller are in rolling press fit in opposite directions. The laminating rubber roller is arranged above the laminating steel roller, and the laminating steel roller moves relative to the laminatingrubber roller so as to adjust the press fit gap. According to the invention, the problem of poor appearance of a final product of the pressure-sensitive adhesive caused by wrinkles of a release film during lamination due to adhesion and electrostatic adsorption of the rubber roller is solved.

Description

technical field [0001] The invention relates to the technical field of industrial adhesive bonding technology, in particular to a pressure-sensitive adhesive bonding device and a bonding method. Background technique [0002] Pressure-sensitive adhesives are mainly acrylic and rubber-based solvent-based or latex-based adhesives; [0003] The composition of pressure-sensitive adhesive adhesive tape is a special type of adhesive, that is, the glue is applied to the substrate and processed into a strip and supplied on a reel, including solvent-activated adhesive tape, heating adhesive tape and pressure-sensitive adhesive tape. Adhesive tape. For example, adhesive plasters and electrical insulating adhesives used daily in medicine belong to pressure-sensitive adhesive tapes. Composition includes rubber type and resin type. [0004] At present, there are more and more applications of pressure-sensitive adhesives, the scope is wider and wider, and the requirements are becoming s...

AI Technical Summary

Problems solved by technology

[0005] More and more new materials are used in pressure-sensitive adhesives, such as PET, PP, PU, ​​PVC, PE, copper foil, aluminum foil, non-woven fabrics, foam cotton, ultra-thin films and other products are introduced / transferred to production , such as wrinkles in the production of ultra-thin tapes, resulting in low production efficiency and high scrap rate, and wrinkles in the production of laminating unit glue and ultra-thin substrate

[0006] The research process of the prior art mainly includes factors such as pressing angle, pressure, adjusting the softness and hardness of the rubber roller, and eliminating static electricity. The results show that the softness and electrostatic adsorption of the rubber roller have an effect on the wrinkling of the 4um ultra-thin PET film during pressing. important impact, thus disclosing the technical solution of choosing a suitable rubber roller and destaticizing method to solve the wrinkling of ultra-thin PET film in the coating lamination state. The current technical solution will harden the rubber roller during long-term use and needs to be replaced regularly , has the disadvantage of high operating costs. At present, there is an urgent need to produce a process and device for the pressure-sensitive adhesive bonding ultra-thin PET film that is more convenient, fast, high-quality and low-cost.
