What are the functions of the four systems of the protective film coater?

The protective film coater is composed of four systems: Master coil conveying system, coating system, heating and drying system and cooling system. What are their functions? Today, Xiaobian will break it down with you

Master coil conveying system of protective film coater: single station lifting and lifting unwinding mode is adopted, equipped with two 3-inch convex key inflatable shafts, 5kg magnetic powder brake to control unwinding tension, and the overall frame adopts EPC hydraulic automatic deviation correction and pneumatic film connecting mechanism to ensure stable operation of the machine during unwinding and improve production efficiency.

Coating system of protective film coater: it adopts the coating mode of anilox coating (two coating combination types of positive pressure and reverse wiping adhesive), and is equipped with 4 anilox rollers, plane control system with glue, double-sided scraper, aluminum alloy pressing plate, transition roller and other devices. The movement type is rubber roller, demoulding and glue equalizing. The up and down movement is controlled by air cylinder with limit protection. The air pressure can be adjusted and controlled by solenoid valve.

Heating and drying system: electric, hot air, steam, heat transfer oil and other heating methods are adopted. The inner and outer walls and air ducts are made of cold rolled plates; The nozzle is made of cold rolled sheet and white zinc plating. The interior is filled with 80mm ultra-fine glass wool, which can keep the temperature at 105-115 ℃ and ensure that the coating meets the process requirements.

Cooling system: the cooling roller with hard chromium plating on the surface cools and shapes the belt, and is equipped with power roller with Teflon anti sticking layer on the surface, arc stretching roller made of Buna-N rubber, transition roller made of aluminum alloy and EPC hydraulic hole corrector, which provides guarantee for neat and beautiful winding of protective film coater.
