　　Coating machine is an efficient and fast production machine in today's society, mainly used for product processing and lamination. The production speed of the coating machine is fast, improving product efficiency. Coating composite is mainly used for the gluing, coating, and processing of various materials such as freezing, drying, plastic film, paper, aluminum carbide, fabric, and leather. It is widely used in various packaging fields and has a broad development prospect. The coating composite equipment can be roughly divided into three types: coating on the light roller, coating on the mesh roller, and hot melt adhesive spray coating.

　　1. Glue coating on the light roller: The amount of glue applied is adjusted by the gap between the two light rollers. The accuracy of the rollers should be high, and the installation position should be precise.

　　2. Mesh roller scraper type glue coating: The glue roller is selected with mesh and dot shapes, and the scraper uses a comma scraper to scrape off the glue on the surface of the glue roller, retaining the glue in the mesh or concave points. After transfer to the substrate, the amount of glue applied is controlled by the mesh size of the mesh roller or dot roller.

　　3. Melt glue coating: After heating and melting the solid glue, the glue is applied to the coating die by a hydraulic device and directly sprayed onto the substrate. Hot melt adhesive coating is currently available and does not require drying equipment, resulting in low energy consumption; Hot melt adhesive is 100% solid adhesive and does not contain toxic organic solvents. Usually, toxic organic solvents (such as benzene) are used to dilute the adhesive for adhesive coating, which can cause damage to the operators due to the toxic gases it produces. Hot melt adhesive coating is green and environmentally friendly, with fast production speed, high efficiency, low cost, small equipment footprint, short investment recovery period, and economic benefits. It has been widely used in packaging, medicine, cars, clothing, electronics and other professions.
