After being re-fixed by the fixing bolts 21 through the multiple sets of reserved holes 22 with equal spacing, the installation distance between two adjacent sets of cutting blades 11 can be adjusted to adjust the width of the polyurethane film for slitting.

[0026] The top of the top box 2 is provided with a top cover 6, and the top two sides of the top cover 6 are respectively installed and fixed with housings 8. The two housings 8 are respectively connected to the interior of the top box 2. A fan 25 is installed inside the bottom of the housing 8. A coarse filter screen 23 is inserted into the top of the front end of the housing 8, and a fine filter screen 24 is inserted into the bottom of the front end of the housing 8. The feed inlet 3 and the discharge outlet 14 respectively penetrate through the interior of the top box 2 and are connected to the interior of the top box 2.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, the controllable fan 25 can start to filter the outside air through the coarse filter 23 and the fine filter 24 and then draw it into the top box 2, so that the air pressure inside the top box 2 is higher than that outside. Excess air can be discharged out through the feed inlet 3 and the discharge outlet 14 to maintain a positive pressure environment inside the device and prevent dust from the external environment from entering the device, thus providing auxiliary dust prevention for the inside of the device.

[0028] Locking rods 7 are provided on both sides of the top front end of the top cover 6, and the bottom end of the locking rods 7 penetrates the interior of the top cover 6. Fixing feet 18 are fixed on both sides of the rear end of the top cover 6. Mounting brackets 19 are fixed on both sides of the top rear end of the top box 2. The fixing feet 18 are hinged to the interior of the mounting brackets 19. Discharge ports 14 are provided on both sides of the top front end of the top box 2. The locking rods 7 are provided with external threads. The bottom end of the locking rods 7 is rotatably connected to the discharge port 14. A handle 9 is fixed at the middle position of the top front end of the top cover 6.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, after the locking rods 7 are turned outward from the inside of the discharge port 14 on both sides of the top front end of the top cover 6, the top cover 6 can be unlocked on the top of the top box 2. Then, the handle 9 can be used to flip the top cover 6 upward to open the inside of the device and perform quick maintenance operations on the inside of the device.

[0030] Two sets of conveying rollers 4 are movably installed vertically on the left side inside the top box 2. Two sets of drive motors 15 are movably installed vertically on the left side at the rear end of the top box 2. An auxiliary roller 13 is movably installed at the bottom inside the top box 2. Two sets of conveying rollers 12 are movably installed vertically on the right side inside the top box 2. Two sets of drive motors 17 are movably installed vertically on the right side at the rear end of the top box 2. A drive motor 16 is installed at the middle position at the rear end of the top box 2. Viewing windows 5 are fixed on both sides of the top box 2. The output shafts of the two sets of drive motors 15 are fixedly connected to the rear ends of the two sets of conveying rollers 4. The output shafts of the two sets of drive motors 17 are fixedly connected to the rear ends of the two sets of conveying rollers 12. The output shaft of the drive motor 16 is fixedly connected to the rear end of the mounting roller 10.

[0031] Working Principle: In use, the cutting blade 11 is unlocked from the outside of the mounting roller 10 by unscrewing the upper and lower sets of fixing bolts 21 from the corresponding pre-drilled holes 22 on the fixing sleeves 20 at both ends of the cutting blade 11. The cutting blade 11 can then be moved back and forth. After being re-fixed by the fixing bolts 21 through the multiple sets of equally spaced pre-drilled holes 22, the installation distance between adjacent sets of cutting blades 11 can be adjusted, allowing for different widths of polyurethane film cutting. The film is introduced into the device through the feed inlet 3, bypassing two sets of conveying rollers 4, and fed into the bottom of the mounting roller 10. The film is then cut using the rotating sets of cutting blades 11. Simultaneously, during device operation, the blower 25 can be activated to draw outside air through the coarse filter 23 and fine filter 24 into the top chamber 2, making the internal air pressure of the top chamber 2 higher than the external pressure. Excess air can be discharged outward through the inlet 3 and outlet 14, maintaining a positive pressure environment inside the device and preventing dust from the external environment from entering the device, thus providing auxiliary dust prevention. After unscrewing the locking rods 7 outward from the outlet 14 on both sides of the top front end of the top cover 6, the top cover 6 can be unlocked from the top of the top chamber 2. Then, the handle 9 can be used to flip the top cover 6 upward to open the device's interior for quick maintenance.
