Problems solved by technology
[0004] In view of the existing pre-coating type laminating machine proposed in the background technology, the glue is heated and melted unevenly, which leads to insufficient adhesion between the film and the printed matter, the situation of easy demoulding, and the problem that the powder on the surface of the printed matter cannot be effectively removed by using a brush. The present invention Provides a pre-coating laminating machine for printed matter processing, which has the advantages of preheating the film and effectively absorbing powder through static electricity, and solves the problem of separation between printed matter and film and the low quality of printed matter after lamination caused by powder residue. unsightly problem

The invention relates to the technical field of printed matter processing, and discloses a pre-coating laminating machine for printed matter processing, which includes a machine body, a film release roller, a tension roller group, a hot pressing roller group, a repressing roller group, and a transfer table. The film release roller and the tension roller group are fixedly installed on the top of the body, and the inside of the body is provided with a heat-pressing roller group and a re-pressing roller group. There is a preheating mechanism located on the underside of the tension roller group for frictional heat generation. The pre-coating laminating machine for printed matter processing converts kinetic energy into thermal energy through the sliding friction between the preheating mechanism and the film, increases the temperature of the film surface, promotes the melting of the glue on the film, and reduces the contact time between the film and the hot pressing roller group. The uneven melting of the film caused by the short film improves the uniformity of glue melting, which helps the firmness of the printing and film lamination, solves the problem of film separation between the printed matter and the film, and improves the quality of the printed matter lamination.
Description
technical field [0001] The invention relates to the technical field of printed matter processing, in particular to a pre-coating type laminating machine for printed matter processing. Background technique [0002] The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper, board and film lamination. It is pressed together by a rubber roller and a heating roller to form a paper-plastic product. Compared with the ready-to-coat laminating machine, the biggest feature of the pre-coating laminating machine is that there is no glue coating and drying part. Therefore, the pre-coating laminating machine has a compact structure, small size, low cost, easy operation, and high product quality. It has good stability and is widely used in the laminating process of printed products. The traditional pre-coated laminating machine includes four main parts: pre-coated plastic film unwi...
