This coater is used for the coating production of BOPP sealant tape. Coating a layer of glue, paint or ink with specific functions on the rolled substrate, drying and rolling. Using special high-speed coating head can effectively reduce the generation of bubbles. The winding and unwinding of the coater are equipped with full-speed automatic film-connecting mechanism, and the tension is automatically controlled in closed loop.
The working process of the coater: coating a layer of glue, paint or ink with specific functions on the rolled paper, cloth, leather, aluminum foil, plastic film and other substrates. And drying and winding.
film plating machine
Working principle of automatic coating machine: The working principle of automatic coating machine for screen printing plate is the same, but its performance is different according to different models and manufacturers. The screen coater is equipped with a device that can clamp the screen frame on the vertical frame. In front of and behind the screen area is a horizontal coating mechanism, which consists of a coating tank and mechanical or pneumatic components that control 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, and the coating mechanism moves up and down through the transmission of belts, chains or cables to coat along the screen surface. The transmission mechanism is connected with servo or variable frequency motor to make it run stably and accurately control the position of the coating mechanism.
Before coating, load the clean and stretched screen from the front of the coater, and some models can also load the screen from the side. Among the models designed for large-format screen frames, side mounting is more common, because the screen frame is large in size and can make the lifting movement smaller. When the automatic screen coater runs online with other automatic screen processing equipment (such as cleaning equipment, recycling equipment, drying device and developing machine), it is more convenient to install the plate from the side. No matter how the screen is installed, once the screen is in the correct position, the pneumatic clamping device or the mechanical clamping device is closed to lock the screen. In order to make the operation more convenient, many models have pedal control panel clips, and the operator can free up his hands to control the screen. After installing the screen, load the corresponding emulsion into the automatic coating machine, and then start coating. According to the functions of the control system and equipment, the equipment can coat both sides of the screen at the same time. There are two coating methods. One is to coat photosensitive adhesive on the screen through multiple wet pressing operations; Or adding a drying process after each coating. A machine for quantitatively coating liquid (or molten) polymer materials (such as adhesives or paints) on the surface of materials.
Suitable for the production of soft substrates such as PVC/PE film.
Simply put, it is to glue the film. It specifically includes gluing, drying, winding and tension control. The film can be PVC, PE, PET ... or some paper. For example, in order to meet the packaging requirements of containerized storage, transportation and mechanized loading and unloading of goods, a series of products such as pallet coater, top pressure stretching coater and pre-stretching automatic coating machine have been designed and manufactured, which are widely used in foreign trade export, food and beverage, irrigation, paper making, dyes, plastics and chemicals, glass ceramics and so on. The working principle of the coating machine is to put the wrapped object in the center of the turntable, start the turntable motor to rotate, and naturally drive the turntable to rotate, so that the object can realize the peripheral film winding machine. At the same time, the elevator motor is also started to drive the whole assembly of the winding and binding machine to move up and down, so as to realize the winding of the object in the height direction and the winding and packaging of the overall appearance of the object. such
It is not only beneficial to the packaging requirements of goods storage, transportation and mechanized loading and unloading operations, but also can prevent goods from being damaged during handling, play a role in dust prevention, moisture prevention and cleaning, reduce production costs and improve production efficiency. In the winding process, it is mainly to adjust the tension of the film and penetrate the film. Generally, film tension can be achieved by adjusting the rotating speed of turntable and motor. As long as we know that the faster the turntable rotates and the slower the motor rotates, the tighter and looser the film will be, and the principle is not difficult to operate.
Application of coater;
Suitable for gluing shoes, electronics industry, sponge, EVA, PE, cloth, etc.
