The outer wall of one end of the sleeve 6 is fixedly connected to a slitting knife 7, and the outer wall of the other end of the sleeve 6 is sleeved with a positioning ring 8, and a limiting mechanism 9 is installed on the lower surface of the positioning ring 8, and limiting holes 10 are evenly spaced on the surface of the bracket 3 below the slitting knife 7. The outer wall of the end of the bracket 3 is sleeved with a frame sleeve 11, and the upper surface end of the frame sleeve 11 is fixedly connected to a support plate 12, and the inner wall of the support plate 12 is movably connected to a square sleeve 13, and the inner wall of the frame sleeve 11 on the side of the support plate 12 is movably provided with a knob 14.

[0025] The transmission square rod 5 and the sleeve 6 form a sliding structure, which is convenient for the user to push the sleeve 6 to slide relative to the transmission square rod 5, thereby adjusting the position of the slitting knife 7 or disassembling the slitting knife 7.

[0026] The sleeve 6 and the positioning ring 8 are rotatably connected, so that the motor 4 drives the transmission square rod 5 to rotate, so that the transmission square rod 5 drives the sleeve 6 to rotate relative to the positioning ring 8, thereby making the sleeve 6 drive the slitting knife 7 to rotate stably.

[0027] The limiting mechanism 9 includes a limiting rod 901 and a limiting tube 902, and the limiting rod 901 is fixedly connected to the lower surface of the positioning ring 8, and the outer wall of the lower end of the limiting rod 901 is sleeved with a limiting tube 902, which is convenient for limiting the slitting knife 7 through the limiting mechanism 9, so that the slitting knife 7 can work stably.

[0028] The limiting tube 902 is threadedly connected to the limiting rod 901 and the limiting hole 10 respectively, so that the user can rotate the limiting tube 902 so that the limiting tube 902 moves relative to the limiting rod 901 and disengages from the limiting hole 10, thereby facilitating the user to adjust the position of the slitting knife 7 or disassemble the slitting knife 7.

[0029] The frame sleeve 11 and the bracket 3 are slidingly arranged, and the square sleeve 13 and the transmission square rod 5 are slidingly connected, so that when the user moves and disassembles the frame sleeve 11, the frame sleeve 11 drives the square sleeve 13 to slide relative to the transmission square rod 5.

[0030] The square sleeve 13 and the support plate 12 form a rotating structure, so that when the transmission square rod 5 rotates, the transmission square rod 5 drives the square sleeve 13 to rotate relative to the support plate 12, thereby making the transmission square rod 5 rotate stably.

[0032] Working principle: When using the adjustable slitting equipment for protective film production, first Figure 1-5 As shown, the user first adjusts the position of the slitting knife 7 according to demand. At this time, the user rotates the limiting tube 902, and then the limiting tube 902 moves up relative to the limiting rod 901 so that the limiting tube 902 disengages from the limiting hole 10. Next, the user pushes the sleeve 6 to move along the transmission square rod 5. At this time, the sleeve 6 drives the slitting knife 7 to move for position adjustment. When the position adjustment of the slitting knife 7 is completed, the user rotates the limiting tube 902 in the opposite direction, and then the limiting tube 902 moves down relative to the limiting rod 901 so that the limiting tube 902 is inserted into the new limiting hole 10. The remaining slitting knives 7 are operated in the same way to complete the position adjustment of the slitting knife 7. Therefore, the device is convenient for adjusting the position of the slitting knife 7 according to demand, thereby facilitating the device to process protective films of different widths, thereby improving the practicality of the device. Then the user positions the protective film on the conveying mechanism 2, and then the user starts the motor 4, and then the motor 4 drives the transmission square rod 5 Rotate, at this time the transmission square rod 5 drives the square sleeve 13 to rotate relative to the support plate 12, so that the transmission square rod 5 drives the sleeve 6 to rotate stably relative to the positioning ring 8, next the sleeve 6 drives the slitting knife 7 to rotate, and then the user drives the protective film to move through the transmission mechanism 2. When the protective film passes through the slitting knife 7, the slitting knife 7 slits the protective film. When the slitting knife 7 needs to be disassembled and maintained after being used for a long time, the user turns off the transmission mechanism 2 and the motor 4, and then the user rotates the knob 14 to disengage the knob 14 from the bracket 3, and then the user moves the frame sleeve 11 to disengage from the bracket 3. At this time, the frame sleeve 11 drives the square sleeve 13 to disengage from the transmission square rod 5, and then the user rotates the limiting tube 902 to disengage the limiting tube 902 from the limiting hole 10, and then the user moves the sleeve 6 to disengage the sleeve 6 from the transmission square rod 5, thereby completing the disassembly of the slitting knife 7, so the device is convenient for disassembling the slitting knife 7 for maintenance.
