The automatic laminating machine is divided into three parts: gluing, drying tunnel and hot pressing.
(1) 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 adopts rubber roller or steel roller.
(2) Drying tunnel part
The drying tunnel is generally 2~3m long. The drying tunnel entrance of the automatic laminating machine is provided with an infrared lamp tube and an electric fan. There is also a high-power electric heating tube and exhaust fan on the upper part of the drying path of the automatic automatic film 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 the coating, which is directly related to the adhesion fastness of the coating 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 consists of a set 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.
