[0002] An OCR coating device for uniform coating usually evenly coats a coating on a target surface through a coating roller. The coating roller takes out the coating from a storage tank and evenly distributes the coating on the material to be coated through precisely controlled pressure and speed. The key of the device lies in controlling the flow rate of the coating and the coating thickness to ensure that the surface coating is uniform and defect-free.

The paint inside the delivery pipe is conveyed to the inside of the discharge nozzle through the shunt rack, and then the discharge nozzle sprays the paint to the position slightly to the left of the middle of the top of the coating roller I to prevent the paint from shifting to the right side of the coating roller I and directly spraying onto the surface of the material. Then the paint moves downward and accumulates between the material blocking block and the coating roller II, so that the paint rolls along the surface of the coating roller II without falling downward. When the material passes through the gap between the coating roller I and the coating roller II, the paint is evenly coated on the top and bottom of the material at both ends, and uniform paint coating can be effectively realized without the assistance of a scraper.

At the same time, the micro motor is operated, the output end of the micro motor rotates the motor rotating rod, and the motor rotating rod rotates the fan blade to circulate the air inside the drying outer shell, so that the heat inside the drying outer shell is transmitted to the surface of the material to dry the coating, preventing the surface of the material from being directly blown and damaging the undried surface coating.

The material guiding rod guides the dried materials. At the same time, the material guiding rod rotates the third belt. The third belt rotates the material collecting rod, so that the materials are wound along the surface of the material collecting rod for collection, reducing energy consumption and improving efficiency, making the moving speed of the materials balanced throughout the process and not prone to wrinkles.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
