Working principle and characteristics of the coating machine : The coating machine is used for the coating production of BOPP sealing tape. Coat the rolled substrate with a layer of glue, paint or ink with specific functions, and wind it after drying. It uses a dedicated high-speed coating head, which can effectively reduce the generation of air bubbles. The rewinding and unwinding of the coating machine are equipped with a full-speed automatic film splicing mechanism, and the tension is automatically controlled by a closed loop.

　　The working process of the coating machine: Coat the rolled substrate, such as paper, cloth, leather, aluminum foil, plastic film, etc., with a layer of glue, paint or ink with specific functions, and then wind it after drying.

　　Suitable for the production of flexible substrates such as PVC/PE film. Simply put, the glue is applied to the film. Specifically, it includes gluing, drying, winding and tension control. The film can be PVC, PE, PET... or some paper.

　　In order to meet the packaging requirements of cargo containerized storage, transportation and mechanized loading and unloading operations, a series of products such as tray coating machines, pressure top resistance stretch coating machines, and pre-stretch automatic film coating machines have been designed and manufactured, which are widely used in foreign trade. The container cost of products such as export, food and beverage, irrigation, papermaking, dyes, plastic chemicals, glass ceramics, electromechanical castings, etc., improve production efficiency, and prevent damage to the goods during the handling process, and prevent dust, moisture and cleaning effect.

Working principle of automatic hot melt adhesive coating machine:

　　The structure of the combined blade coating head and the application profile of soft and hard blades The structure of the combined blade coating head:

　　(1) The characteristics and functions of the combined blade coating head:

　　The blade coating is conventionally controlled and operated by adjusting the blade angle. But the combined scraper is supplemented without changing the angle of the scraper. Only change the blade pressure load to control the characteristics of the coating amount.

　　This helps prevent squeegee marks or coating quality problems when changing the coating amount. This is especially important in low basis weight coatings. In order to change the pressure load on the tip of the scraper, the clamping beam with the scraper is moved in or out on the guide rail. However, the position of the scraper pressure bracket is not changed.

　　A hand in the alliance will always be a friend! Focus on the production of coating machines, laminating machines, shoe material laminating machines, leather processing machines, high quality and low price! Warmly welcome new and old customers to visit and guide!
