Garret laminating machine has what kind of coating form

       Garritt company specializing in the production of laminating machine, automatic laminating machine, glazing machine, automatic glazing machine, non-adhesive laminating machine and other products, because focus on this for many years, but also accumulated some practical experience, the following Xiaobian and everyone to talk about the laminating machine what form of coating? There are mainly roller reverse type, concave type, direct gluing without scraper and direct gluing with scraper, etc.

1, concave type glue. It IS composed OF A metal coating roller WITH MESH ON the surface and a group of film partition rollers. The coating roller is directly immersed in the glue liquid, and the glue liquid is brought out from the glue storage tank with the rotation of the roller, and the excess glue liquid on the surface of the roller is scraped off by a scraper. Under the action of the press film roller, the glue in the groove of the roller is driven by the directional motion of the film to be coated and evenly spread on the surface of the film. The amount of coating can be controlled by adjusting the surface grid pattern of the coating roller, the characteristic value of the adhesive, the pressure value of the film pressing roller, etc. The advantage of concave coating is that the amount of coating can be controlled accurately and the coating is uniform. But roller processing is difficult, easy to damage, often need to clean, in addition to coating on the adhesive higher requirements.

2, roller reverse type gluing. Is an indirect glue, is the most used in various models of one. The supply roller takes out the glue liquid from the glue storage tank, and the glue scraping roller and the glue scraping plate can scrape the excess glue liquid back to the glue storage tank. The back pressure roll of film laminating machine will press the film to be coated to the surface of the coated roller after uniform glue, and maintain a certain contact area, under the action of pressure and adhesive force, the glue liquid is constantly coated on the surface of the film. The amount of glue can be changed by adjusting the distance between the squeegee roller and the squeegee roller and the rubber plate.

3. Squeegee roller extrusion type gluing. The rubber roller is directly immersed in the rubber solution, and when coating, the rubber solution is taken out by the rubber roller, and the glue is coated by the extrusion pressure between the film roller and the rubber roller.
