[0023] See also Figure 1-4 As shown, a protective film reeling device includes a reeling machine 1, a cutter 2 for cutting the protective film is arranged inside the reeling machine 1, fixed disks 3 are arranged on the left and right sides of the inner side of the reeling machine 1, the left fixed disk 3 is rotatably connected to the inner wall of the reeling machine 1, and the right fixed disk 3 is fixed to the driving shaft of the reeling machine 1, an arc groove 4 is provided on the surface of the fixed disk 3, a reeling roller 5 is arranged inside the arc groove 4, and limiting holes 6 are provided on the top of both ends of the reeling roller 5, the top of the fixed disk 3 is threadedly connected to a fixing bolt 7 used in conjunction with the limiting hole 6, and a torsion plate 18 is fixed to the top of the fixing bolt 7, so that it is convenient for the user to apply force to the fixing bolt 7 to rotate the reeling machine 1 The inner side is rotatably connected with a fixed rod 10, and a fixed frame 11 is fixed on the surface of the fixed rod 10, and a number of movable rods 12 are movably connected inside the fixed frame 11, one end of the movable rod 12 is fixed with a concave plate 13, and the inner side of the concave plate 13 is rotatably connected with a pressure roller 15, and a spring 14 is provided on the surface of the movable rod 12, and the two ends of the spring 14 are respectively fixed to one side of the fixed frame 11 and the concave plate 13. In this way, with the elastic force of the spring 14 itself, the movable rod 12 and the pressure roller 15 can always be driven to move outward, thereby improving the clamping effect. A force structure 16 for driving the fixed rod 10 to rotate is provided on the right side of the reeling machine 1.

[0024] The force-applying structure 16 includes a motor 161, a transmission rod 162, a first gear 163 and a second gear 164. The motor 161 is fixed on the right side of the reeling machine 1, and the output shaft of the motor 161 is fixed to one end of the transmission rod 162. The other end of the transmission rod 162 extends to the inner side of the reeling machine 1 and is fixed to one side of the first gear 163. One side of the first gear 163 is meshed with the second gear 164, and the interior of the second gear 164 is fixed to one end surface of the fixed rod 10.

During the winding process, the fixed rod 10, the fixing frame 11, the concave plate 13 and the pressure roller 15 can be driven by the force structure 16 to deflect the angle, so that the pressure roller 15 can contact the paper tube sleeved on the surface of the winding roller 5. As the winding roller 5 rotates, the protective film is wrapped around the surface of the paper tube, and the wrapped protective film can be pressed tightly by the pressure roller 15. After the winding is completed, the protective film can be cut by the cutter 2. After that, the staff can first unscrew the fixing bolt 7, and then use the force structure 16 to drive the fixing rod 10, the fixing frame 11, the concave plate 13 and the pressure roller 15 back to the starting position, and finally remove the winding roller 5.
