The coating machine is used for the coating production of BOPP sealing tape. Roll is the process of applying a specific functional adhesive, paint, or ink to the substrate and drying it after winding. Adopting a special high-speed coating head can effectively reduce the generation of bubbles. The film coating machine is equipped with a full speed automatic film receiving and releasing mechanism, and tension closed-loop automatic control. The workflow of the coating machine: The rolled substrate, such as paper, fabric, leather, aluminum foil, plastic film, etc., is coated with a layer of specific functional adhesive, paint, or ink, and then dried after winding. The working principle of the automatic coating machine: The working principle of the screen printing plate automatic coating machine is the same, but its performance varies according to different models and manufacturers. The silk screen coating machine is equipped with a device that can clamp the mesh frame onto the vertical frame. The front and rear of the screen area are horizontal coating mechanisms, consisting of a coating tank and a mechanical or pneumatic part that controls the angle and pressure of the coating tank.
The two ends of the coating mechanism are installed on the vertical support arm of the coating machine, which is driven by a belt, chain, or cable to move the coating mechanism up and down and apply along the surface of the screen. The transmission mechanism is connected to a servo or variable frequency motor, ensuring stable operation and precise control of the position of the coating mechanism. Before coating, install a clean and stretched screen from the front of the coating machine, and some models can also install the screen from the side. In the design of large grid models, side panels are more common because the grid is large and bulky. Side panels can reduce the amount of lifting and movement. When operating online with automatic screen coating machines and other automatic screen processing equipment (such as cleaning equipment, regeneration equipment, drying equipment, and developing machines), it is more convenient to publish from the side. Regardless of the loading method, once the loading position is correct, the pneumatic or mechanical clamping device is closed and the screen is locked. In order to make operation easier, many models have pedal control panels, which allow operators to freely control the panels with both hands. After the screen is installed, the automatic coater will put in the corresponding lotion to start coating. According to the control system and device functions, the device can simultaneously coat both sides of the screen. There are two coating methods: one is to apply photosensitive emulsion on the silk screen through a multi wet operation; Alternatively, add a drying process after each coating. A machine for quantitatively coating liquid (or melt) polymer materials, such as adhesives or coatings, on the surface of the material. Simply put, it means applying glue to the film. Specifically, it includes gluing, drying, winding, and tension control. The film can be PVC, PE, PET... it can also be some paper. The hot melt adhesive coating machine on release paper is designed and manufactured to meet the packaging requirements of containerized storage, transportation, and mechanized loading and unloading of goods. We have designed and manufactured a series of products including tray coating machines, top resistance drawing coating machines, and pre drawing automatic coating machines. Widely used in the cost assembly of products such as exports, food and beverage, irrigation, papermaking, dyes, plastic chemicals, glass ceramics, electromechanical casting, etc., to improve production efficiency, prevent damage to goods during transportation, and play a role in dust prevention, moisture prevention, and cleaning.
