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 apply a layer of glue, paint or ink with specific function on the rolled substrate (such as paper, cloth, leather, aluminum foil, plastic film, etc.), and then take up the roll 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, etc.
Working principle and characteristics of coater:
The coater is used for coating BOPP sealing tape. The rolled base material is coated with a layer of glue, paint or ink for specific functions, and then dried before winding. It uses a special high-speed coating head, which can effectively reduce the generation of bubbles. The take-up and take-off of the coater are equipped with a full speed automatic film connecting mechanism, and the tension closed-loop automatic control.
Working process of coater: apply a layer of glue, paint or ink on the rolled base materials, such as paper, cloth, leather, aluminum foil, plastic film, etc., and dry them before winding.
It is suitable for the consumption of PVC / PE film and other soft base materials
Simply put, it is to apply glue to the film. Detailed including gelatinization, drying, winding and tension control. Film can be PVC, PE, pet... Can also be some paper
In order to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading of goods, we have designed and manufactured a series of products, such as tray coater, pressure top drag coater and pre pull automatic film coater. They are widely used in the containerization cost of export, food and beverage, irrigation, papermaking, dyestuff, plastic and chemical industry, glass ceramics, mechanical and Electrical Castings, to improve consumption efficiency In addition, it can avoid the damage of goods in the process of transportation, and play the role of dust-proof, moisture-proof and cleaning.
Working principle of automatic hot melt adhesive coater:
The structure of the coating head of the combined scraper and the application of the soft and hard scraper
（1） The characteristics and functions of the combined scraper coating head are as follows
Generally, the blade coating is controlled and operated by adjusting the blade angle. But the combined scraper is added without changing the scraper angle. Only change the pressure load of the scraper to control the coating characteristics.
This helps to avoid the scratch or coating quality problems when changing the coating amount. This is particularly important in low weight coating. In order to change the pressure load on the top of the scraper, the clamping beam with the scraper moves in or out on the guide rail. But the position of the pressure bracket of the scraper is not changed.
