A hair roller 508 is fixedly connected to the outer surface of the support shaft 507. A connecting block 509 is fixedly connected to the inner surface of the bracket 506 near the upper side of the support shaft 507. A plurality of nozzles 510 are fixedly connected to the lower surface of the connecting block 509 at equal intervals. A first connecting pipe 511 is fixedly connected to the outer surface of the connecting block 509. A liquid pump 512 is fixedly connected to the end surface of the first connecting pipe 511. A second connecting pipe 513 is fixedly connected to the input end of the liquid pump 512. A liquid storage tank 514 is fixedly connected to the end surface of the second connecting pipe 513.

[0022] The effect achieved by the entire embodiment 1 is that when the PETG film is produced and rolled up, the PETG film is rolled up from the film roller 7 on the left to the film roller 7 on the right. When the PETG film passes under the wool roller 508 during the transportation process, the hydraulic rod 4 is started to extend to drive the wool roller 508 to move down and fit the surface of the PETG film. The PETG film will contact the wool roller 508 during transportation. Through the setting of the support shaft 507, the wool roller 508 will rotate. Compared with the anti-static brush, the wool roller 508 is softer and is not easy to cause scratches and wear on the surface of the PETG film. During use, the liquid pump 512 is started, and the liquid pump 512 can extract water in the liquid storage tank 514 through the second connecting pipe 513 , and then the water is transported to the connecting block 509 through the first connecting pipe 511, and the nozzle 510 is started to spray atomized water from the top of the wool roller 508 to wet the wool roller 508. When the wool roller 508 rotates and contacts the PETG film, a layer of water will be evenly applied to the surface of the PETG film. The free ions in the water molecules can be adsorbed on the surface of the PETG film to neutralize the electrostatic charge on the PETG film, thereby eliminating the static electricity of the PETG film. Compared with the traditional static electricity removal method in which the static electricity removal brush rubs against the surface of the PETG film, the wet wool roller 508 is softer and absorbs water, and can fully contact the surface of the PETG film to complete the static electricity removal without causing damage to the surface of the PETG film.

[0023] Embodiment 2, as Figure 1-Figure 4 As shown, a plurality of telescopic rods 502 are equidistantly fixedly connected to the lower surface of the mounting plate 501 , springs 503 are sleeved on the outer surfaces of the plurality of telescopic rods 502 , and a support plate 504 is fixedly connected between the lower end surfaces of the plurality of telescopic rods 502 .

[0024] The effect achieved by the entire embodiment 2 is that, through the support of the support plate 504 by the spring 503, the rebound force of the spring 503 can be used to apply a downward force to the bracket 506, and the setting of the telescopic rod 502 can provide support for the spring 503. The setting of the bracket 506 driving the wool roller 508 to always apply force downward can make the wool roller 508 generate downward pressure on the surface of the PETG film, maintain a close fit with the surface of the PETG film, and improve the use effect of the wool roller 508.

[0025] Working principle: when the PETG film is produced and rolled up, the PETG film is rolled up from the film roller 7 on the left to the film roller 7 on the right. When the PETG film passes under the wool roller 508 during transportation, the hydraulic rod 4 is started to extend to drive the wool roller 508 to move down and fit the surface of the PETG film. The PETG film will contact the wool roller 508 during transportation. Through the setting of the support shaft 507, the wool roller 508 will rotate. Compared with the anti-static brush, the wool roller 508 is softer and is not easy to cause scratches and wear on the surface of the PETG film. During use, the liquid pump 512 is started. The liquid pump 512 can extract water in the liquid storage tank 514 through the second connecting pipe 513, and then the water is transported to the connecting block 509 through the first connecting pipe 511. The nozzle 510 can be started to spray atomized water from the top of the wool roller 508 to wet the wool roller 508. When the wool roller 508 rotates and contacts the PETG film, A layer of water is evenly applied to the surface of the PETG film, and the free ions in the water molecules can be adsorbed on the surface of the PETG film to neutralize the electrostatic charge on the PETG film, thereby eliminating the static electricity of the PETG film. Compared with the traditional static removal method in which the anti-static brush rubs against the surface of the PETG film, the wetted hair roller 508 is relatively soft and absorbs moisture, and can fully contact with the surface of the PETG film to complete the static removal without causing damage to the surface of the PETG film. The support of the support plate 504 by the spring 503 can utilize the resilience of the spring 503 to apply a downward force to the bracket 506. The setting of the telescopic rod 502 can provide support for the spring 503. The setting of the bracket 506 driving the hair roller 508 to always apply force downward can make the hair roller 508 generate downward pressure on the surface of the PETG film, keep a close fit with the surface of the PETG film, and improve the use effect of the hair roller 508.
