[0040] Working principle: When the easy-to-clean release film coating equipment is working, firstly, the uncoated release film roll is placed on the unwinding shaft 3. The tension roller 4 adjusts the tension of the release film during the transmission process to ensure that the release film is transported flat. Then, the release film enters the coating stage. The coating liquid stored in the coating box 5 provides raw materials for the coating operation. The nozzle 6 sprays the coating liquid in the coating box 5 evenly onto the surface of the release film. Then, the rotating shaft 7 adjusts the angle of the scraper 8 to achieve coating of different thicknesses. The scraper 8 evenly smooths the coating liquid on the surface of the release film, eliminating the problem of coating liquid accumulation or uneven thickness. During this process, the threaded rod 9 and the nut 10 cooperate to fix the position of the scraper 8 after adjustment to ensure the stability of the rotation of the scraper 8.
[0041] Furthermore, when the coated release film enters the drying mechanism 2, the upper drying oven 202 and the lower drying oven 201 cooperate to form a drying space that wraps around the release film from both above and below. Through all-round heat coverage, the release film is heated evenly, improving the drying quality. At this time, the heat conduction pipe 205 begins to conduct heat, providing a heat source for the drying process and maintaining a constant temperature environment inside the oven. The fan blades 203 begin to rotate to generate airflow, accelerating heat transfer and improving drying efficiency. At the same time, the air distribution plate 204 guides and divides the airflow, making the hot air more evenly distributed inside the oven, avoiding local overheating or underheating of the release film, and ensuring the consistency of the drying effect. The moisture and hot air generated during the drying process are discharged through the air outlet 206 to ensure a stable drying environment and prevent imbalance of humidity and temperature inside the oven, thereby ensuring the drying effect.
