Multi-purpose type double-sided film laminating system

Abstract

The invention discloses a multi-purpose type double-sided film laminating system applied to a film laminating machine. The multi-purpose type double-sided film laminating system comprises a rack (14), an upper film roller (1) and a hot-pressing mechanism, wherein a gluing mechanism and a drying mechanism (5) are installed in sequence on the rack and above the hot-pressing mechanism, and a preheating roller (13) and a lower film roller (10) are installed in sequence on the rack and below the hot-pressing mechanism. An extension roller (11) is installed on the rack and between the preheating roller and the lower film roller, and the extension roller is connected with an extension power source (12).According to the multi-purpose type double-sided film laminating system, instant coating or precoating can be flexibly selected, so that the convenience is provided for the next processing procedure after a film is laminated on paper, the film can be effectively prevented from generating wrinkles during operation, a big enough wrap angle between the film and the preheating roller is guaranteed so as to be fully preheated, and the film laminating quality is high. The multi-purpose type double-sided film laminating system has the advantages of reasonable structure, simplicity in operation, energy conservation, environmental friendliness and high heat utilization rate, multiple purposes of one machine are realized, and the multi-purpose type double-sided film laminating system can be widely used for various paper materials.

Description

technical field [0001] The invention relates to a printing device, in particular to a double-sided laminating system applied to a laminating machine. Background technique [0002] At present, the laminating machine can be divided into two categories: the instant coating laminating machine and the pre-coating laminating machine. It is a special laminating equipment for paper post-press processing. The ready-to-coat laminating machine mainly includes three parts: gluing, drying, and hot pressing. It has the advantages of wide application range, low cost, stable and reliable processing performance, etc. It is the most widely used laminating equipment at present; The film machine does not need adhesives and heating and drying systems, and can directly carry out the hot pressing process, which greatly simplifies the film lamination process, and is easy to operate, can be opened at any time, and has no solvent smell, no environmental pollution, and can completely avoid air bubbles...

AI Technical Summary

Problems solved by technology

However, the existing small amount of semi-automatic and fully automatic double-sided laminating equipment is improved on the basis of pre-coating laminating machines. Meet the lamination requirements of paper of different materials and thicknesses

For some papers, due to the quality defects of the pre-coated film to a certain extent, poor temperature control during use will cause degradation and cross-linking of the high molecular polymer in the hot melt adhesive, which will easily cause insufficient adhesion to the printed matter and gloss on the surface Defects such as fog spots with different degrees

Due to the vacancy of ready-to-coat double-sided laminators in the printing industry, for such products that cannot be used with pre-coated double-sided laminators or with poor pre-coated film lamination effects, only one-sided printing can only be done first. Laminating, after the lamination of one side is completed, then laminating the other side in turn is time-consuming and laborious, and the work efficiency is low, which cannot meet the work needs of producers
