The principle and advantages of automatic coating machine?

The coating machine is used for the coating production of BOPP sealing adhesive tape. The rolled base material is coated with a layer of adhesive, paint or ink with specific functions, and then dried before winding. It uses a special high-speed coating head, which can effectively reduce the generation of bubbles. The winding and unwinding of the coating machine are equipped with a full-speed automatic film receiving mechanism, and the tension closed-loop automatic control.
The working process of the coater: apply a layer of adhesive, paint or ink with specific functions to the rolled base materials, such as paper, cloth, leather, aluminum foil, plastic film, etc., and dry them before winding.
Working principle of automatic coater: The working principle of automatic coater for screen printing and plate making is the same, but its performance varies according to different models and different manufacturers. The screen coater is equipped with a device that can clamp the screen frame on the vertical frame. The front and rear of the screen area is a horizontal coating mechanism, which is composed of the coating tank and the 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 belt, chain or cable to coat along the surface of the screen. The transmission mechanism is connected to the servo or variable frequency motor to make its operation stable and accurately control the position of the coating mechanism.
What are the advantages of coating machine system control?
1. Tension control and synchronization control are completed by frequency converter, without additional controller, and the electric control system has simple structure.
2. Modular structure design is adopted. Although the production line is long and there are many links, debugging, operation and maintenance are very convenient.
3. For special models, the factory value can meet the system requirements without resetting the converter parameters.
4. The tension in the production process is constant, the control precision is high, the substrate will not be damaged, the coating effect is uniform, and the product quality is good.
5. The winding tension of the finished product is constant, completely avoiding the situation of tight inside and loose outside.
