[0036] Working principle: when the release film 18 is rolled up toward the winding roller 39, the release film 18 passes through the bottom of the first positioning roller 24, the bottom of the shower head 26, the middle of the cleaning brush 28, the bottom of the water-absorbing cleaning sponge 30, the bottom of the second positioning roller 24, between the upper pressure roller 35 and the lower pressure roller 36, the upper part of the roller 47, the upper part of the cutting plate 40, and then is rolled up by the winding roller 39. When the release film 18 reaches the lower part of the shower head 26, the water pump 50 can make the water in the water storage tank 2 enter the shower head 26, so that the shower head 26 sprays the release film 18. The release film 18 after being wetted by the spray of water passes between the cleaning brushes 28, so that the cleaning brushes 28 clean the release film 18. The cleaned release film 18 reaches the lower part of the water-absorbing cleaning sponge 30, so that the water-absorbing cleaning sponge 30 cleans the release film 18 again and absorbs the water on the release film 18. Then, the release film 18 passes through the lower part of the second positioning roller 24 and enters between the upper pressing roller 35 and the lower pressing roller 36. Since positioning rollers 24 are arranged on both sides of the shower head 26, the cleaning brush 28 and the water-absorbing cleaning sponge 30, the release film 18 can be 18 can stably pass through the shower head 26, the cleaning brush 28 and the water-absorbing cleaning sponge 30, which is convenient for cleaning; when the release film 18 is between the upper pressing roller 35 and the lower pressing roller 36, the upper pressing roller 35 and the lower pressing roller 36 press the release film 18, so that the release film 18 is more flat, and because the upper pressing roller 35 is driven by the first telescopic column 32 and the first spring 33 to move up and down, it is avoided that the force between the upper pressing roller 35 and the lower pressing roller 36 is too large to cause the release film 18 to be damaged, and then the release film 18 passes through the roller 47 and the fixed plate 38 surface, so that the release film 18 The film 18 is wound by the winding roller 39, and when the release film 18 passes through the surface of the roller 47, the release film 18 can drive the roller 47 to rotate, and the angle sensor 48 can detect the number of revolutions of the roller 47, so that when a certain number of revolutions is reached, the angle sensor 48 transmits a signal to the central control component 52, and the central control component 52 operates the electric push rod 49 to move the electric push rod 49 downward, thereby driving the cutting blade 42 to cut the release film 18, thereby ensuring that the length of the release film 18 wound on the winding roller 39 is consistent.
