Presswork production coating machine

Abstract

The invention relates to a presswork production coating machine. The coating machine comprises a supporting stand, a material placing stand, a heating device, a flattening device (4) and a heat sealing device. The invention solves the difficulties that existing presswork production coating machines fail to realize even and smooth heating of a thin film in the process of thin film heating, gas between a presswork and the thin film cannot be successfully exhausted, so the presswork cannot be closely attached to the thin film, wrinkles and bubbles are therefore caused on the surface of the presswork and the coating effect is influenced. Meanwhile, the invention solves the difficulties that existing equipment fails to timely remove a hot melting block in the process of heat sealing of the thinfilm, so after long-hour operation of the hot melting block, a lot of melted thin films are adhered to the surface of the hot melting block, heat on the surface of the hot melting block cannot be transferred out, heat sealing is not tight, and the gloss, smoothness and aesthetic appearance of a coated film are affected.

Description

technical field [0001] The invention relates to the technical field of printing and laminating, in particular to a laminating machine for making printed matter. Background technique [0002] With the continuous development of the printing industry, a laminating machine for printing has become particularly important. The laminating machine can be divided into two categories: instant coating and pre-coating. It is a special equipment for paper, board, and laminating film. , pressurized by the rubber roller and the heating roller to form a product that combines paper and plastic. The laminating machine is not only suitable for laminating processing of large-scale printed matter, but also suitable for automated desktop office systems. It has broad development prospects. It is to increase the gloss and smoothness of the surface of the printed matter, and make the printed matter more vivid and bright, so that the printed matter has the properties of waterproof, anti-fouling, foldi...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing film making and laminating machine cannot evenly heat the film when heating the film, and cannot discharge the gas between the printed matter and the film well, resulting in a low degree of adhesion between the printed matter and the film, resulting in Wrinkles and air bubbles appear on the surface of the printed matter, which affect the effect of the film. At the same time, it can solve the problem that the existing equipment cannot clean the hot melt block in time when the film is heat sealed. After the hot melt block works for a long time, the surface of the hot melt block will be damaged. Adhering to a large number of melted films, the surface of the hot melt block cannot conduct heat, resulting in a loose heat seal, which affects the gloss, smoothness and aesthetics of the coating.
