Brief analysis of laminating machine manufacturers There are two major types of laminating equipment: instant coating laminating machine and pre-coating laminating machine. The instant coating laminator has a wide application range, stable and reliable processing performance, and is a widely used laminating device. Pre-coated laminating machine, no gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for laminating processing of large batches of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems .
        The laminating machine manufacturers briefly analyze the coating forms of the laminating machine: drum reversal type, concave type, direct glue without scraper, and direct glue with scraper.
        1. Brief analysis of concave glue application by laminating machine manufacturers. It consists of a metal glue roller with a textured surface and a group of film partition rollers. The glue roller is directly immersed in the glue solution, and the glue solution is taken out from the glue storage tank with the rotation of the roller. The excess surface is scraped off by the scraper Glue. Under the action of the film pressing roller, the glue in the groove of the roller is driven by the film to be coated which is directionally moved and is evenly spread on the film surface. The amount of glue can be controlled by adjusting the grid pattern on the surface of the coating roller shaft, the characteristic value of the adhesive, and the pressure value of the laminating roller. The advantage of concave coating is that it can control the amount of coating more accurately and coat evenly; however, the anilox roller is difficult to process and easy to damage, and it needs to be cleaned frequently. In addition, the coating requires higher adhesives.
        2. The manufacturer of the film laminating machine briefly analyzes the reversal coating of the roller. It is an indirect glue coating, which is the most widely used by various models. . The glue supply roller brings out glue from the glue storage tank, and the glue scraping roller and the glue plate can scrape the excess glue back to the glue storage tank. The film counter-pressure roller of the laminator presses the film to be applied to the surface of the glue roller after the glue is homogenized, and maintains a certain contact area, and the glue solution is continuously coated on the surface of the film under the action of pressure and adhesion. The amount of glue can be changed by adjusting the distance between the rubber roller and the rubber roller, and the rubber roller and the rubber sheet.

        3. A brief analysis of the laminating machine manufacturers without squeegee roller extrusion coating. The glue roller is directly immersed in the glue liquid. During the coating, the glue roller brings out the glue liquid and passes through the glue roller. After the glue is evenly glued, the glue is applied by the pressing force between the film pressing roller and the glue roller.
