Aluminum plastic film composite coating machine is made by introducing foreign advanced coater technology and combining its own years of experience in the production of coaters. This machine uses two coating functions, namely, scraper coating for adhesive tape, self-adhesive adhesive, electrical protective film, etc., and the screen coating for silicone oil, PE protective film, which is widely applicable to the production of adhesive tape, self-adhesive adhesive, electrical protective film, PE protective film, release paper, release film and other coating products.
1. The aluminum plastic film composite coating machine is controlled by 5 frequency conversion motors. The tension of the whole machine (unwinding, coating, traction, winding) is automatically controlled by Mitsubishi PLC system. The reliability of the tension of the whole machine is improved through the man-machine interface touch screen control and display.
2. The feeding rack is in the form of electric overturning double station, which adopts magnetic powder automatic tension control.
3. Comma scraper coating method, the comma scraper roller clutch adjustment adopts pneumatic swing arm type, the swing arm is equipped with a micro adjustment device to control, and the glue thickness is controlled by a feeler gauge.
4. Anilox coating method: the coating scraper shaft adopts heavy double axis mechanical independent swimming, the scraper adjustment mode is manual with pneumatic, and the angle can be adjusted at will. The coating amount depends on the mesh line of the anilox roll. Different coating amount can be replaced with different mesh lines of the anilox roll.
5. The oven is 22 meters long, and the first 20 meters are divided into 8 sections for independent temperature control. The heating is conducted by circulating heat transfer oil. The hot air enters the drying system, and the adjustable internal circulation suction and exhaust device. The air inlet and exhaust are strong, and the drying is complete. A UV drying system is reserved for the last 2 meters.
6. The guide wheel in the oven is actively synchronized with the host machine, and the transmission is synchronous pulley driven, which can reduce the material stretching and deformation. The open top air cylinder oven and the membrane piercing operation platform make it easy for operators to work.
7. Coating roller — the middle tension of traction steel roller is synchronized with the floating swing arm, which is automatically controlled by PLC
8. Automatic meter and speed control device
9. EPC edge aligning machine is used for deviation correction to ensure the tidiness of material winding.
10. Key type air expansion shaft is adopted for retraction and retraction, which is convenient for loading and unloading.
11. High precision upward pressure traction device, steel roller cooling adopts water circulation type, through which the film is more flat, more scraping, and more cooling effect is achieved.
