After the cutting wheel spacing is adjusted, the knob 6 is rotated again to drive the threaded rod to rotate in the opposite direction, drive the pressing block 8 to approach the square tube 2, and fix the adjusting block 4 at the new position, thereby completing the adjustment of the cutting width and ensuring that the slitting machine can meet the production requirements of different widths. The collecting groove 21 is slidingly connected to the inside of the bottom of the mounting seat 1. The waste generated during the cutting process falls into the collecting groove 21 slidingly connected to the inside of the bottom of the mounting seat 1, which is convenient for centralized cleaning and keeps the working area clean. The rack 3 is fixedly connected to the outside of the end of the mounting seat 1.
[0038] Working principle: first, one end of the polypropylene film is inserted through the gap between the two adjusting roller shafts 17 rotationally connected to the inside of the two ends of the sliding frame 16 on the rack 3, then the film is guided to pass below the first guide roller shaft 18 rotationally connected to the inside of one end of the mounting seat 1, then the film is passed above the cutting roller shaft 19 rotationally connected to the inside of the middle of the mounting seat 1, then the film is passed through the second guide roller shaft 20 rotationally connected to the inside of the other end of one of the mounting seats 1 located above, then the film is passed through the gap between the two second guide roller shafts 20, and finally the end of the film is fixed together with the winding device. After the film is inserted, the electric push rod 15 in the lifting assembly is started, the end of the electric push rod 15 is fixed to the inside of the top of the rack 3, and the telescopic movement of the electric push rod 15 drives the sliding frame 16 to move up and down, thereby driving the polypropylene film between the two adjusting roller shafts 17 to move up and down, so as to tension and adjust the polypropylene film to be cut.
[0039] After the polypropylene film tensioning work is completed, the winding device is started, the winding device provides power to move the polypropylene film, at this time, the cutting wheel 10 installed on the support frame 9 at the bottom of the adjusting block 4 is supported by the pressure rod 11, and is divided into strips along with the movement of the film. The pressure roller 12 on the inner side of the two ends of the pressure rod 11 plays an auxiliary role.
[0040] By rotating the knob 6 in the positioning and fixing assembly, the knob 6 drives the threaded rod 7 to rotate in the threaded hole 5 inside the adjusting block 4, so that the pressing block 8 fixedly connected at the end of the threaded rod 7 moves away from the square tube 2, thereby loosening the adjusting block 4. After loosening the adjusting block 4, the adjusting block 4 is actuated to slide in the through slot 22 formed in the middle of the square tube 2, thereby driving the cutting wheel 10 fixed at the bottom thereof and the pointer 13 fixedly connected at the end to move. During the adjustment process, the scale 14 provided at one end of the top of the square tube 2 is referred to, and the distance between the two cutting wheels 10 is adjusted according to the production requirements. After the cutting wheel 10 spacing adjustment is completed, the knob 6 is rotated again to drive the threaded rod 7 to rotate in the opposite direction, so that the pressing block 8 is close to the surface of the square tube 2, thereby fixing the adjusting block 4, completing the cutting width adjustment, and improving the flexibility of the polypropylene production slitting machine.
