The oven coil composite coating machine is suitable for coating non-elastic materials such as paper, film, aluminum foil, plastic, non-woven fabrics, etc. It has the functions of unwinding, scraping, drying, laminating, and rewinding. It is an automatic composite coating machine for oven coils, using slit coating.
The oven coil composite coating machine is a multi-functional composite equipment with the functions of unwinding, scraping, drying, laminating and rewinding. The following is an introduction to the main structure of the device:
Unwinding device: The unwinding device is located at the starting end of the equipment and is used to place the substrate reel to be compounded. It usually includes components such as reel supports, tensioning devices and rollers to ensure stable conveying and tensioning of the substrate.
Blade coating system: The blade coating system is a key component in the coating process. It uses slit coating technology to evenly coat molten polyethylene plastic on the surface of the substrate. The system includes a coating roller, a coating tank, a blade and a roller, etc., which can achieve precise coating control.
Drying system: The drying system is located after the doctor blade coating system and is used to solidify the polyethylene plastic coated on the surface of the substrate to improve the quality and stability of the composite film. Drying systems usually use electric heating or hot air circulation, and the temperature and drying time can be adjusted as needed.
Composite device: The composite device is a key component that combines the coating on the surface of the substrate with another layer of substrate. It usually includes composite rubber rollers, pressure rollers and heating devices to ensure the firmness and uniformity of the composite film. The heating temperature of the composite rubber roller can reach 200°C to ensure good adhesion of the composite film.
Rewinding device: The rewinding device is located at the end of the equipment and is used to collect the completed film rolls. It usually includes components such as a winding device, a tensioning device and a winding reel, which can achieve stable collection and tensioning of film rolls and facilitate subsequent packaging and transportation.
