[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-4 As shown, a protective film cutting device comprises a support rod 5, a connecting shaft 9, a collecting mechanism and a fixing structure 2;

[0028] A limit ring 14 is provided on the surface of the connecting shaft 9, and a flexible blade skin 1 is attached to the surface of the limit ring 14 by magnetism, and is reinforced by a fixing structure 2;

[0029] A fixed disk 4 is fixedly installed on the surface of the support rod 5, and a rotating disk 8 is rotatably connected to the surface of the fixed disk 4. A mounting nail 3 is provided on the surface of the fixed disk 4, and a mounting nail 2 is provided on the surface of the rotating disk 8. A wire is fixedly connected to the surface of the mounting nail 27, and a metal rod 10 is provided at the other end of the wire on the surface of the mounting nail 27. A through groove 12 is opened on the surface of the connecting shaft 9, and the other end of the metal rod 10 passes through the through groove 12 and fits with the flexible knife skin 1. A wire is fixedly connected to the surface of the mounting nail 3, and the other end of the wire on the surface of the mounting nail 3 is fixed to the ground;

[0030] The collecting mechanism is installed below the fixed disk 4 and is used to collect the debris generated by the friction between the fixed disk 4 and the rotating disk 8. The inner wall of the connecting shaft 9 is fixedly connected with a bracket 13. The metal rod 10 is slidably connected to the bracket 13 through a spring. The end of the metal rod 10 close to the flexible blade skin 1 is arc-shaped.

[0031] During operation, the metal rod 10 is connected to the rotating disk 8 through a wire, and then the rotating disk 8 is connected to the ground with another wire, so that the static electricity on the flexible knife skin 1 can be directed to the ground, thereby preventing the static electricity on the surface of the flexible knife skin 1 from adsorbing the protective film. There is a carbon brush structure between the fixed disk 4 and the rotating disk 8, so that the wire can be prevented from being entangled or knotted while the flexible knife skin 1 is rotating. At the same time, the elastic sliding metal rod 10 cooperates with the curved surface on the top, so that the metal rod 10 can fit the flexible knife skin 1 more closely. By cooperating with the rotating disk 8 and the fixed disk 4, the metal rod 10 cooperates with the rotating disk 8 and the fixed disk 4, compared with the Chinese patent with publication number CN213971583U, which opens air holes for blowing, it can avoid static electricity adsorption and improve compatibility, and can also avoid clogging of the air holes or inaccurate hole position correspondence, which causes the flexible knife skin 1 to flip up and affects the subsequent cutting effect. In addition, by not opening holes, the overall rigidity of the flexible knife skin 1 can be increased to ensure the cutting effect.

[0032] The collecting mechanism includes a storage box 15, which is arc-shaped and matches the outer diameter of the fixed disk 4. The surface of the support rod 5 is fixedly connected with a fixed shaft 6, and a slot 22 is provided in the fixed shaft 6. A block 18 is slidably connected with the slot 22 through a spring. A card plate 17 is fixedly connected with the surface of the storage box 15, and a through hole matching the fixed shaft 6 is provided on the surface of the card plate 17. A limit plate 16 is slidably sleeved on the surface of the fixed shaft 6. The limit plate 16 fits the surface of the card plate 17, and the limit plate 16 is slidably connected to the surface of the fixed shaft 6 through a spring. The surface of the block 18 has an arc angle.

[0033] During operation, the debris generated by the friction between the fixed disk 4 and the rotating disk 8 can be collected through the storage box 15 for easy cleaning by the staff, and then the block 18 is squeezed in the direction of approaching each other so that the block 18 releases the positioning of the card plate 17. At this time, the collection box is slid downward, and the card plate 17 is driven to separate from the fixed shaft 6, and the collection box is disassembled for easy cleaning. During installation, the arc angle on the surface of the block 18 can improve the installation efficiency.

[0034] A guide rod 21 is slidably connected inside the fixed shaft 6, and the guide rod 21 is arc-shaped. A notch 23 is provided on the surface of the block 18 relative to the position of the guide rod 21. A connecting rod 20 is fixedly connected to the surface of the guide rod 21, and the other end of the connecting rod 20 passes through the fixed shaft 6 and is fixedly connected to a knob 19. During operation, the stability during fixation can be improved because two blocks 18 are provided, but it is not convenient to disassemble. At this time, the knob 19 is directly rotated to make the knob 19 drive the connecting rod 20, and the connecting rod 20 drives the guide rod 21 to slide, so that the guide rod 21 squeezes the notch 23, so that the two blocks 18 move in a direction close to each other, and the disassembly efficiency of the collection box can be further improved by the knob 19.

[0035] Embodiment 2

[0036] Compared with Example 1, as another implementation of the present invention, the surface of the knob 19 is provided with anti-skid grooves; during operation, the anti-skid grooves on the surface of the knob 19 can increase the friction between the operator's fingers and the knob 19 to avoid slipping.
