The optical film coating machine comprises a frame, a rear roller mechanism arranged on the frame, a feeding roller mechanism, a hopper mechanism and a scraper.

The hopper mechanism of the product has inverted trapezoidal column layout, inverted triangular column layout and approximate semi-cylindrical layout, and the hopper mechanism is equipped with coating agent; The feeding roller mechanism of the product is soaked and fixed in the hopper mechanism; By changing the cylinder form of the feeding mechanism, the height of the feeding mechanism on the rack is increased, so that the height of the feeding roller is not easily lower than the liquid level of the coating agent, which ensures the coating agent and saves the coating agent. The layout of the optical film coating machine is simple and reasonable, the coating is high and uniform, and the finishing is convenient.
The optical film coating machine needs to evenly adhere glue and ink on the surface of aluminum foil, plastic film and cloth textiles. It has high requirements for coating technology, which not only requires the coating to be highly symmetrical, but also can realize high-speed roll change without stopping, and improve production compliance.
The optical film coating machine comprises a frame, a rear roller mechanism set on the frame, a feeding roller mechanism, a hopper mechanism and a scraper. The hopper mechanism of the product is an inverted trapezoidal cylinder structure, an inverted triangular cylinder structure, and a semi-cylinder structure. The hopper mechanism is equipped with coating agent; The feeding roller mechanism of the product is soaked and fixed in the hopper mechanism; By changing the cylinder shape of the feeding mechanism and improving the height of the feeding mechanism on the rack, the height of the feeding roller is not easily lower than the liquid level of the coating agent, which ensures the coating agent. The optical film coating machine has the advantages of simple and reasonable organization, high and uniform coating, and easy finishing.
Working principle of optical film coater: The working principle of automatic optical film coater used for screen printing plates is similar, but its functions are different according to different models and different manufacturers. The vertical frame of the screen optical film coater is equipped with a device that can clamp the screen frame, and the front and rear of the screen area are optical film coating mechanisms, It is composed of a coating tank and a machine part or pneumatic part used to control the angle and pressure of the coating tank.
The drying channel of the optical film coating machine consists of several cascaded ovens and a conveyor installed in each oven for conveying paint. Each oven has an air nozzle that can effectively blow paint onto the conveyor. The air nozzle in the oven is a single-side air nozzle. The single-side air nozzle of the product is staggered up and down along the conveying direction of the conveyor on the conveyor in the oven. The blowing direction of all single-side air nozzles is the same, The conveying direction of the conveyor is the same or opposite. The drying channel of the optical film coating machine uses single-sided and double-sided nozzles to dry the coated material. After the substrate is coated, the single-sided nozzle is used for simple drying with hot air, which improves the drying compliance of the slurry and ensures the uniformity of the slurry.
