Laminating machine composition
1 gluing part. The gluing part is equipped with an adjusting device to adjust the amount of gluing to meet the requirements of different printing parts. The rubber roller or the steel roller is used for the gluing roller.
2 bake section. The drying tunnel is generally 2 to 3 meters long. The baking tunnel of the laminating machine is equipped with infrared lamps and electric fans. There are high-power electric heat pipes and exhaust fans on the upper part of the tunnel of the automatic laminating machine, and the temperature can be adjusted to dry the adhesive and remove the exhaust gas.
3 hot pressing part. This part is the key to the film, which is directly related to the adhesive fastness of the film products. The principle of hot-pressing is that the adhesive can quickly infiltrate and penetrate into the surface of the print in the molten state, so as to obtain a firm bond interface layer. The hot press part consists of a set of rollers. One of the hollow metal drums, equipped with electric heating tube, the temperature can be controlled. This set of roller pressure can be adjusted.
Film laminating (vacuum laminating machine) is to apply adhesive to plastic film, and print it with paper as printing material, and press the rubber roller and heating roller together to form a paper-plastic product.
Laminating machines can be divided into two categories, ie, the coating type laminating machine and the precoating type laminating machine. The coating type laminating machine includes three parts: sizing, drying, and hot pressing. The application scope thereof is wide, and the processing performance is stable and reliable. It is a film coating apparatus widely used in China at present. Precoat laminating machine, no glue and dry part, small size, low cost, flexible and convenient operation, not only for the processing of large quantities of printed films, but also for the coating of small batches and scattered prints such as automated desktop office systems Processing is very promising.
