[0002] Artificial leather base fabric is the base material for making artificial leather, and the artificial leather base fabric often needs to be cut before it can be used. The slitting device uses multiple cutters installed on the equipment to cut the artificial leather base fabric passing through. For example, the utility model patent with announcement number CN205997039U discloses a slitting device, in which a plurality of cutters are arranged on the knife roller of the device, and the plurality of cutters are evenly distributed along the length direction of the knife roller. And the knife body is fixedly arranged on the knife roller and is integral with the knife roller. In the production process, due to different market demands, the width of the artificial leather base fabric to be cut is also different. When using an integrated knife roller, the manufacturer needs to purchase knife rollers of different specifications. Cutting artificial leather base fabric requires that the cutting surface is free of burrs, the cross section is neat, and the cutter is sharp. Therefore, the cutter needs to be replaced in time after it is worn. The cutter of the slitting device with an integrated structure cannot be replaced individually, and needs to be replaced as a whole, which increases the production cost. Utility Model Content

[0025] In a specific embodiment, Figures 1 to 5 As shown, the utility model of the artificial leather base cloth slitting device, the rotating mechanism includes a bracket 8, bearings are installed at both ends of the bracket 8, the bearings are placed on the column 2, a block 3 is provided on the upper end surface of the column 2, and a fixing screw is provided on the block 3 to fix the bearing between the column 2 and the block 3. A stepper motor 1 is provided at the lower end of the column 2, and the stepper motor 1 passes through the column 2 and is connected to the second gear 5 through a coupling, and the second gear 5 is meshed with the first gear 4, and the first gear 4 is installed at both ends of the bracket 8. The motor drives the first gear 4 to rotate, so that the bracket 8 rotates accordingly, and there is a limit structure on the bracket 8 to allow rotation of a certain angle. The slide rail 6 is installed on the bracket 8 by countersunk bolts, and a plurality of slitting units 7 are provided on the slide rail 6, and the plurality of slitting units 7 are guided and slid on the slide rail 6.

[0026] Specifically, the slitting unit 7 includes a slider base 701, which is a ball slider and is slidably connected to the slide rail 6. The slide rail is provided with scale lines, and the position of the slider base 701 is set according to the cutting width. The top of the slider base 701 is provided with a threaded hole and a locking bolt 702, and the slider base 701 is pressed on the slide rail 6 by the front end of the locking bolt 702. A tool holder 703 is provided on the other side of the slider base 701, and a limiting step is provided in the tool holder groove of the slider base 701. A plane limiting step is provided on the upper end of the tool holder 703. The installation position of the tool holder 703 is limited by the step to ensure that the step installation height is consistent, so that the entry point during cutting is guaranteed to be consistent. The lower end of the tool holder 703 is a 7-shaped structure, and a servo motor 707 is installed on the outer side of the 7-shaped structure. The servo motor 707 is connected to a base fabric disc knife 704 through a coupling, and the base fabric disc knife 704 is fixed by a nut 706 on the other side.

[0027] In a specific embodiment of the present invention, Figure 4 As shown, the base fabric disc knife 704 is made of high-quality stainless steel, with high hardness and wear resistance. The servo motor 707 drives the base fabric disc knife 704 to rotate highly, easily cutting the artificial leather base fabric, and the blade is flat.

[0028] In a specific embodiment of the present invention, Figures 5 to 7As shown, the upper end of the knife holder 703 is circular, with planes on the two side surfaces, and the lower ends of the two planes are provided with a first limiting step 7033 and a second limiting step 7034, the two limiting steps are not at the same height, and the arc surfaces on both sides are respectively provided with a first groove 7031 and a second groove 7032, the two grooves are not at the same height, and the height difference of the two limiting steps is consistent with the height difference of the two grooves.
