Description of the structure of the glue-free laminating machine
Non glue laminating machine is generally divided into glue, dry, hot press three parts. Let's take a closer look.
The gluing part of a glueless laminating machine. The gluING part IS equipped with a adjusting device to adjust the amount of gluing to meet the requirements of different printing parts. The gluing roller is made of rubber roller or steel roller.
The dry passage part of the glueless laminating machine. The baking channel is generally 2 ~ 3m long. An infrared lamp tube and an electric fan are provided at the drying opening of the glue-free laminating machine. There are high power electric heat pipes and exhaust fans on the drying channel of automatic laminating machine. The temperature can be adjusted to make the adhesive dry and remove exhaust gas.
The hot pressing part of the glueless laminating machine. This part is the key to the film, directly related to the film product bond fastness. The principle of hot pressing is that the adhesive in the melting state can quickly infiltrate and penetrate into the surface of the printing, so as to obtain a firm binding interface layer. The hot pressing part consists of a set of rollers. One of the hollow metal rollers is equipped with an electric heat pipe and the temperature can be controlled by itself. This set of drum pressure can be adjusted.
