2. Application and working principle of coater

The coater is suitable for gluing of shoe material, electronic industry, BOPP sealing tape, sponge, EVA, PE, pet, cloth, etc.

Working principle of coater: it is to coat the rolled substrate (such as paper, cloth, leather, aluminum foil, plastic film, etc.) with a layer of glue, paint or ink with specific functions, and then roll up after drying. It adopts special high-speed coating head, which can effectively reduce the generation of bubbles. The winding and unwinding are equipped with full speed automatic film connecting mechanism, double or single station, tension closed-loop automatic control device, etc.

3. Work flow of laminating machine (compound machine)

Laminating machine (compound machine) generally includes: coating, drying, hot pressing, cooling

① Coating unit

According to different machine design, there are roller coating and scraper coating. The glue coating surface is also different from the cloth surface, the cloth surface or the film surface. Different gluing methods make the situation of glue penetration and film formation on the substrate different. Of course, the following effect is also different. In addition, the presence or absence of the grain on the coating wheel and the pattern of the grain will also affect the difficulty of carrying glue and the form of glue coating (full coating, dot coating...). The coating wheel with special texture can be combined with the corresponding glue to produce high-performance products, such as air permeability, super soft handle, etc.

② Drying unit

Whether or not the oven is long or short and the way of drying (hot air circulation or infrared assisted) also varies with the type of machine selected and the roller or scraper coating. The volatilization rate of glue solvent is closely related to the drying conditions of the machine, so how to adjust to the appropriate temperature required by the material is very important to make it still have good adhesion.

③ Hot pressing unit

The size of the hot pressing wheel, the surface temperature and the pressing time are related to the volatilization efficiency of the residual solvent, the activation degree of the glue and the bonding effect.

④ Cooling unit

Before crimping, the finished product is cooled by the cooling wheel, which can promote the crystallization of the glue, improve the initial adhesion, and avoid the displacement of the laminating material during coiling.
