[0031] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of this utility model are now described with reference to the accompanying drawings. However, the scope of protection of this utility model is not limited to the following description.

[0032] Reference Figure 1-6 As shown, a constant temperature drying mechanism for a protective film coating machine includes: a base 1; a drying chamber 2, which is disposed on the top of the base 1; and two hot air blowers 8, which are respectively disposed at the top two ends of the drying chamber 2.

[0033] The drying chamber 2 has two rotating drive rollers 23 inside, and a conveyor belt 6 is tensioned and connected to the two drive rollers 23. The conveyor belt 6 has multiple through holes 14. A second motor 7 is installed at one end of the drying chamber 2, and the output end of the second motor 7 is connected to one end of the drive rollers 23. A winding unit is installed at one end of the base 1 for winding the protective film.

[0034] Mounting plates 12 are arranged opposite each other on both sides of the conveyor track 6. Two clamping rollers 13 rotate relative to each other between the two mounting plates 12. Two gears 18 are rotatably arranged on one side of one mounting plate 12. The two gears 18 mesh with each other. One end of the clamping roller 13 is connected to the gear 18. A handle 19 is rotatably arranged on one side of the other mounting plate 12. One end of the handle 19 is connected to one of the clamping rollers 13. A limit sleeve 20 is slidably arranged on the other mounting plate 12. The bottom of the limit sleeve 20 is open. A groove 21 is opened on one side of the other mounting plate 12. The limit sleeve 20 is slidably connected to the groove 21 through a slider.

[0035] The present invention provides a technical solution in which, during use, the protective film is placed on the conveyor belt 6, the second motor 7 is started to drive the drive roller 23 to rotate, and the drive roller drives the conveyor belt 6 to rotate. The protective film is then conveyed to the inside of the conveyor box 2 and dried in the drying box 2. This allows for the convenient drying of continuous or discontinuous protective films, making them convenient to use. The protective film can be wound up by the set winding unit.

[0036] When conveying the protective film, one end of the protective film is inserted between the two clamping rollers 13. Then, the handle 19 is rotated, which drives the clamping rollers 13 to rotate. The gear 18 drives the two clamping rollers 13 to rotate synchronously relative to each other, allowing the protective film to pass through the two clamping rollers 13. Then, the rotation is stopped, and the limiting sleeve 20 is moved downward so that it is placed on the handle 19, fixing the handle 19 and the clamping rollers 13, thereby fixing the protective film. This facilitates subsequent conveying, prevents displacement and detachment, and is convenient for conveying discontinuous protective films. When drying continuous protective films, one end of the protective film is connected to the winding unit, and then the limiting sleeve 20 is moved upward to remove the fixation of the handle 19. The protective film is then wound up by the winding unit, allowing it to pass between the two clamping rollers 13. This provides limiting support for the protective film and facilitates the drying of continuous protective films.

[0037] Preferably, the winding unit includes a mounting frame 3 disposed at one end of the base 1, a winding roller 5 rotatably disposed at the top of the mounting frame 3, and a first motor 4 fixedly disposed on one side of the mounting frame 3, the output end of the first motor 4 being fixedly connected to one end of the winding roller 5.

[0039] Preferably, the drying oven 2 is equipped with an I-shaped frame 15 inside, and pressing rollers 16 are rotatably installed at both ends of the I-shaped frame 15. An electric telescopic rod 9 is installed on the top of the drying oven 2, and the output end of the electric telescopic rod 9 is connected to the I-shaped frame 15.

[0040] Specifically, the electric telescopic rod 9 can drive the I-shaped frame 15 to move up and down, and drive the I-shaped frame 15 to move down so that the pressing roller 16 contacts the protective film, which can limit the protective film and is convenient to use when drying continuous protective film.

[0041] Preferably, the top of the base 1 is provided with an air outlet box 17, the top of the air outlet box 17 is provided with an air outlet, the two sides of the drying box 2 are provided with hot air boxes 10, the inside of the hot air box 10 is provided with an electric heating plate 22, the top of the hot air box 10 is provided with a fan 11, and one end of the hot air box 10 is connected to the inside of the air outlet box 17.
