Problems solved by technology

Therefore, during storage, many plastics have a decline in the effect of corona treatment, and additives migrate from the inside to the surface, which is also a factor that reduces surface energy and affects adhesion. This negative effect cannot be completely suppressed.
[0006] Therefore, buying a commercially available corona film and storing it in advance after corona treatment will affect the coating effect

Embodiment Construction

[0020] See figure 1 .

[0021] The paper cutter 1 and the laminating host 6 form a common laminating unit. A corona machine 4 is added between the paper cutter 1 and the laminating main machine 6, which is the laminating unit with added corona treatment function of the present invention.

[0022] The corona machine 4 is placed on the film release frame 7, so that the position and height of the corona machine and the laminating machine and the paper cutter keep the operation smoothly.

[0023] A film release roller 2 is set on the film release frame 4, and the film release roller 2 is located on one side of the film feeding guide roller 3 of the corona machine 4;

[0024] The corona machine 4 is connected to the control device of the laminating unit to realize linkage with the laminating host 6 and the paper cutter 1 .

[0025] The paper cutter 1 , the laminating host 6 and the film releasing frame 7 are all arranged on the ground 8 .

[0026] The rolled plastic film is loc...

Abstract

The invention provides a film laminating unit with a corona treatment function. According to the film laminating unit with the corona treatment function, a corona machine is arranged between a film laminating main unit of an existing film laminating unit and a paper cutting machine. According to the technical scheme, after corona treatment is conducted on a plastic film on a site for the film laminating procedure, the film laminating procedure is conducted immediately, so that recession of the corona effect of the plastic film after the corona treatment is avoided; in addition, the optimal corona treatment effect is achieved by adjusting corona treatment control factors according to plastic films of different properties and various factors such as the work environment conditions of the site, film laminating requirements and paper quality.

Description

technical field [0001] The invention relates to the surface lamination of printed matter, in particular to lamination equipment, and more specifically to a lamination unit with added corona treatment function. Background technique [0002] The surface of the printed matter is covered with film to improve the brightness, wear resistance, waterproof performance of the printed paper, increase the hardness and folding resistance of the paper; it is suitable for postcards, posters, book covers, information books, color box packaging, handbags, etc. [0003] The film is generally made of plastic. In order to increase the adhesion of the film surface and make the film more firmly attached to the paper, a corona-treated film (corona film) is generally used. [0004] After corona treatment, free radicals are generated on the surface of the plastic and the polymer is cross-linked. The surface roughens and increases its wettability to polar solvents. These ions penetrate into the surf...
