In the printing industry, automatic laminating machines are indispensable, and their work efficiency has been widely recognized, so what are the characteristics of automatic laminating machines? The following editor will take you to understand!
        Automatic laminating machine is a kind of printed material that is made of plastic film through machine processing and printing on paper. This is widely used in people's daily life. It is mainly used in magazines, book covers, packaging boxes, calendars, paper bags, etc. It can be said to be everywhere. In the past, traditional laminating machines had low working efficiency and high labor costs. Nowadays, people have invented automatic laminating machines, which use modern advanced laminating technology to automate paper feeding and cutting, which greatly improves production. Efficiency, reducing the cost of manual input. Not only that, the color of the product after the automatic laminating machine is more beautiful and beautiful, and it is moisture-proof, easy to clean, and durable. Automatic laminating machine is generally composed of three parts: gluing, drying tunnel and hot pressing. For gluing, it mainly uses an adjustment device to adjust the amount of gluing to meet different needs. The drying tunnel mainly uses electric heating tubes and fans to complete the drying of the adhesive on the drying tunnel of 2 to 3 meters. Hot pressing is mainly to obtain a firm interface layer and achieve the purpose of being durable.
        What are the coating forms of the automatic laminator? There are mainly roller reversal type, concave type, direct glue without scraper and direct glue with scraper.
        1. Concave glue application. 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. Reverse roller coating. 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. No-squeegee roller squeeze 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.
