Description

A kind of laminating equipment

technical field

The utility model relates to the technical field of film processing, in particular to a film covering device.

Background technique

Lamination is to bond the plastic film coated with an adhesive to the base material layer, and it is one of the common paper printing products processing techniques at present. The coated printed product has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, which not only improves the gloss and fastness of the printed product, but also significantly improves the grade and added value of the product packaging and prolongs the life of the product. At the same time, the plastic film also plays a protective role such as moisture-proof, waterproof, anti-fouling, wear-resistant, folding-resistant, and chemical corrosion-resistant. Before the film is compounded, the surface of the film needs to be glued first, and then it can be pasted and pressed with the paper printed product. However, after the glue is transferred to the surface of the film, the film usually tightens. At this time, the tightened film It is easy to produce wrinkles. At this time, if it is directly compounded on the surface of the paper printed product, it will cause bubbles and unevenness on the surface of the compounded printed product. At the same time, the effect of moisture and water resistance is not obvious, and the quality of the printed product is poor.

In the preferred version, the gluing mechanism includes a glue storage tank, a rubber transfer roller, a rubber roller, a laminating roller, a doctor blade and a motor, and the glue storage tank, the rubber roller, the laminating roller and the motor are installed on the frame respectively. The upper rubber transfer roller is installed in the rubber storage tank, the upper rubber roller is in contact with the rubber transfer roller and the laminating roller respectively, the scraping knife is attached to the surface of the upper rubber roller, and the upper rubber roller is connected with the output shaft of the motor through transmission. The rubber transfer roller is stained with glue in the glue storage tank and passed to the upper rubber roller. The film passes through the upper rubber roller and the laminating roller during conveying, and the film is in contact with the upper rubber roller under the action of the laminating roller for gluing .

The beneficial effect of the utility model is that the laminating equipment can unfold and straighten the glued film before compounding the film and paper printed products, so that the compounded printing can be completed after the film and paper printed products are compounded. The surface of the product is smooth and smooth, no air bubbles will be generated, the moisture-proof and waterproof effect is good, and the quality of the printed product is better.
