Each drying component 2 includes a drying pipe 21 rotatably connected to the inner wall of the housing 1, and guide rollers 22 arranged in a circular array around the drying pipe 21. The guide rollers 22 are rotatably connected to the inner wall of the housing 1. One side of the drying pipe 21 is fixedly connected to a nozzle 23 arranged in a linear array. A heating air supply component 3 is provided on one side of the housing 1 to supply hot air into the drying pipe 21. Specifically, the protective film passes sequentially through the guide rollers 22 arranged in a circular array, forming a semi-circular movement trajectory; the drying tube 21 is located at the center of the semi-circular trajectory, the protective film moves clockwise, while the drying tube 21 rotates counterclockwise; Specifically, the drying tube 21 and the branch tube 36 are rotatably connected by a sealed bearing; the two sets of drying components 2 are arranged symmetrically to facilitate the placement of the two sets of drying components 2 on both sides of the protective film and to dry the surface of the protective film on both sides.

[0021] Please see Figure 1 , Figure 2 and Figure 4 The heating and air supply assembly 3 includes a wind box 31 installed on one side of the housing 1. A fan 32 and a heater 33 are installed inside the wind box 31. An air inlet 34 is opened on one side of the wind box 31. A main pipe 35 is fixedly connected to the other side of the wind box 31. The end of the main pipe 35 away from the wind box 31 is fixedly connected to two branch pipes 36 through a three-way pipe. The ends of the two branch pipes 36 are installed on one side of the housing 1, and the ends of the two branch pipes 36 are rotatably connected to one end of the two drying pipes 21 respectively.

[0022] Please see Figure 2 , Figure 3 and Figure 4 Gear 4 is rotatably connected to one side of the housing 1. Gear 5 is fixedly sleeved at the ends of the two drying tubes 21. Both gears 5 mesh with gear 4. A servo motor 6 is installed on the housing 1. The output shaft of the servo motor 6 is fixedly connected to the shaft of gear 4. Specifically, the servo motor 6, the fan 32, and the heater 33 are all electrically connected to the power supply; a dust cover can be installed on one side of the housing 1 located on gear 2 5, which covers gear 1 4 and gear 2 5, thereby increasing the dust protection capability of gear 1 4 and gear 2 5.

[0023] Please see Figure 3 and Figure 4 An ultraviolet disinfection lamp 7 is installed on one side of the drying tube 21, and the ultraviolet disinfection lamp 7 and the nozzle 23 are located on both sides of the drying tube 21 respectively. Specifically, when the drying tube 21 is drying, the ultraviolet disinfection lamp 7 emits ultraviolet light during operation to sterilize and disinfect the protective film, further improving product quality. To ensure that the ultraviolet disinfection lamp 7 can rotate with the drying tube 21, and since the drying tube 21 is electrically connected to the power supply via a wire, an electric slip ring can be installed at the end of the drying tube 21 away from the branch pipe 36. The rotating part of the electric slip ring is fixed at the axis of the drying tube 21, and rotates according to the rotation of the drying tube 21. The stationary part of the electric slip ring is fixed to the housing 1, and the ultraviolet disinfection lamp 7 is electrically connected to the electric slip ring, which is in turn electrically connected to the power supply. The slip ring, ultraviolet disinfection lamp 7, servo motor 6, fan 32, heater 33, winding mechanism 14 and cooling component 15 are all existing technology equipment.

Specifically, after the protective film is dried, it is rapidly cooled by the cooling component 15 to quickly lower its temperature, which facilitates subsequent packaging processing; the cooled protective film is then wound by the winding mechanism 14.

[0027] Please see Figure 4 A coarse particle filter 16 is installed at the air inlet 34, and multiple removable fine particle filters 17 are installed inside the air box 31. The fine particle filters 17 are located between the air inlet 34 and the fan 32. Specifically, the coarse particle filter 16 filters coarse particulate impurities in the air; the fine particle filter 17 further filters fine particulate impurities in the air.

[0028] Working principle: The protective film enters the box 1 through the feed inlet 8, passes through the discharge outlet 9, and is finally wound and stored by the winding mechanism 14. Outside air is drawn into the air box 31 through the air inlet 34 by the fan 32. The air is first filtered through the coarse particle filter 16 and the fine particle filter 17 to remove dust and impurities. Then, the air is heated by the heater 33 inside the air box 31 to form hot air. The hot air is transported to the rotating drying tube 21 through the main pipe 35 and the branch pipe 36. The hot air is sprayed out from the nozzle 23 and blown evenly on the surface of the protective film to achieve the drying treatment of the protective film.

[0029] The hot air blown out through the drying pipe 21 is discharged through the exhaust groove on the guide roller 22 and the opening 10 on the box body 1.
