[0021] Reference Figure 1-Figure 3A protective film winding mechanism with a cutting component includes a bottom plate 1, a bracket 2 is welded on the top of the bottom plate 1, an electric push rod 4 is fixedly inserted on the top inner wall of the bracket 2, a cutting knife 5 is fixed to the output end of the electric push rod 4 by bolts, and the cutting knife 5 moves downward under the drive of the electric push rod 4, so as to cut the protective film, a motor 7 is fixed to the top of the bottom plate 1 by bolts, a winding roller 8 is clamped on the output end of the motor 7, and the winding roller 8 rotates under the drive of the motor 7, so as to wind up the protective film, and spring boxes 9 are fixed to both ends of the winding roller 8 by bolts, and the spring box 9 is fixed to the output end of the motor 7 by bolts. A lifting plate 10 is slidably connected in the box 9, and one end between the two lifting plates 10 passes through the spring box 9 and is fixed with a pressure block 13 by bolts. The pressure block 13 is clamped with the winding roller 8, and a lifting rod 12 is welded on the top of the lifting plate 10. The top of the lifting rod 12 passes through the top of the spring box 9, and a spring 11 is sleeved on the outer wall of the lifting rod 12. One end of the spring 11 is fixedly connected to the lifting plate 10, and the other end of the spring 11 is fixedly connected to the top inner wall of the spring box 9. Relax the lifting rod 12, and the pressure block 13 is clamped with the winding roller 8 under the elastic action of the spring 11, thereby pressing the free end of the protective film.

[0022] The inner walls on both sides of the bracket 2 are provided with sliding grooves 3, and the two ends of the cutting knife 5 slide in the sliding grooves 3, so that the cutting operation of the cutting knife 5 is guided, and the cutting stability of the cutting knife 5 is improved. Two guide rods 6 are welded on the top of the cutting knife 5, and the guide rods 6 are slidably plugged with the top of the bracket 2. The cutting operation of the cutting knife 5 is guided by the sliding of the two ends of the cutting knife 5 in the sliding grooves 3 and the design of the guide rods 6, so as to improve the cutting stability of the cutting knife 5. A plurality of fixing pins 14 are welded at the bottom of the pressing block 13, and the fixing pins 14 are plugged with the outer wall of the winding roller 8. The fixing pins 14 pass through the free end of the protective film and are plugged with the winding roller 8, so as to further fix the protective film.

Then, the lifting rod 12 is lifted upward to drive the lifting plate 10 to move upward, thereby driving the pressing block 13 to move upward, and then the pressing block 13 is separated from the winding roller 8. Then, the free end of the protective film is placed on the winding roller 8 and is located at the bottom of the pressing block 13. Then, the lifting rod 12 is loosened, and the pressing block 13 is engaged with the winding roller 8 under the elastic action of the spring 11, thereby pressing the free end of the protective film.
