What are the three most critical parts of the laminating machine? The laminating machine is mainly divided into three parts: gluing, drying tunnel and hot pressing.
        1. The glue part. The gluing part is equipped with an adjusting device to adjust the amount of gluing to meet the requirements of different printed parts. The gluing roller uses rubber roller or steel roller.
        2. Part of the drying tunnel. The drying tunnel is generally 2 ~ 3m long. The drying tunnel of the laminating machine is equipped with infrared lamps and electric fans. There is also a high-power electric heating tube and exhaust fan on the upper part of the drying path of the automatic laminating machine. The temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.

        3. Hot pressing part. This part is the key to laminating, which is directly related to the adhesion fastness of the laminating product. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface layer of the printed matter in the molten state, so as to obtain a strong bonding interface layer. The hot pressing part is composed of a group of rollers. One of the hollow metal rollers is equipped with an electric heating tube, and the temperature can be controlled automatically. The pressure of this group of rollers can be adjusted.
