[0025] See also Figure 1-6 As shown, the embodiment of the utility model provides a film laminating roller device of a film laminating device, specifically comprising a pressure roller 1 and a traction member 2. The pressure roller 1 is cylindrical, the middle section of the pressure roller 1 is a straight pressure portion 11, and the two ends of the straight pressure portion 11 are curved surface portions 12. Both ends of the pressure roller 1 are provided with a rotating shaft 13 and a roller 14. Figure 3 As shown, the traction member 2 includes a crossbeam 21, a handle 22, an inner baffle 24 and an outer baffle 25. The handle 22 is located at the top center of the crossbeam 21. The inner baffle 24 and the outer baffle 25 are arranged at the ends of the crossbeam 21. The pressure roller 1 is rotatably installed between the two inner baffles 24 through the rotating shaft 13. The roller 14 is located between the inner baffle 24 and the outer baffle 25. In this embodiment, as shown in FIG. Figure 2 , 3 As shown, the tops of the inner baffle 24 and the outer baffle 25 are connected via an arc portion 26, and the traction member 2 is mounted on the guide rail 31 of the film applicator base 3 via the arc portion 26. It should be noted that the tops of the inner baffle 24 and the outer baffle 25 can also be connected in other forms, such as a dovetail shape, a square shape, etc.

[0026] like Figure 4 , 5As shown, a guide groove 32 is provided below the guide rail 31 of the film applicator base 3, and the roller 14 of the pressure roller 1 rolls in the guide groove 32, and the roller 14 abuts against the upper and lower surfaces of the guide groove 32 to limit the pressure roller 1 and the traction member 2 from moving up and down, effectively controlling the problems of bubbles and wrinkles during the film applicator process. Figure 5 As shown, the traction member 2 wraps both sides of the guide rail 31 through the inner baffle plate 24 and the outer baffle plate 25 to limit the lateral movement of the traction member 2, effectively improve the film sticking accuracy, and prevent the protective film from being skewed.

[0027] like Figure 3 , 6 As shown, a reinforcing plate 23 is provided on one side below the crossbeam 21, and both ends of the reinforcing plate 23 are connected to the inner baffle 24 to improve the reliability of the traction member 2. The diameters of both ends of the pressure roller 1 are larger than the diameter of the straight pressure portion 11, and the diameter of the curved portion 12 gradually increases from the inside to the outside. In this embodiment, the pressure roller 1 is made of elastic material to adapt to the lamination of different mobile phones 4 and different types of protective films.

[0028] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, the principle thereof is further explained below in combination with the usage method.

[0029] During installation, firstly, the rotating shaft 13 of the pressure roller 1 is passed through the rotating shaft hole 27 of the inner baffle plate 24, and then the roller 14 is installed on the rotating shaft 13, and the rotating shaft 13 is located between the inner baffle plate 24 and the outer baffle plate 25; Figure 6 As shown, the installed pressure roller 1 and traction member 2 are installed from one end of the guide rail 31 of the base 3, the roller 14 is installed in the guide groove 32, the traction member 2 is installed on the guide rail 31 through the arc portion 26, and the inner baffle 24 and the outer baffle 25 wrap the two sides of the guide rail 31. After installation, since the upper and lower ends of the roller 14 abut against the upper and lower ends of the guide groove 32, and the arc portion 26 of the traction member 2 abuts against the guide rail 31, the pressure roller 1 and the traction member 2 cannot jump vertically on the base 3; since the inner baffle 24 and the outer baffle 25 wrap both sides of the guide rail 31, the traction member 2 cannot shift laterally, and at the same time, the two ends of the pressure roller 1 are restricted by the roller 14 and the inner baffle 24, and the pressure roller 1 cannot shift laterally, effectively preventing the protective film from being distorted. When the screen of the mobile phone 4 is a curved surface, the curved portion 12 of the pressure roller 1 presses the curved surfaces on both sides of the screen to ensure that the protective film is completely fitted to the screen of the mobile phone 4.
