[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, a slitting mechanism of a nonwoven tape production slitting machine according to an embodiment of the present invention includes a base plate 1, on which a production mechanism is provided. The production mechanism includes: a slitting component, including a first concave frame 2 fixedly connected to the top of the base plate 1, rectangular holes 3 on both sides of the first concave frame 2, concave sliders 4 slidably connected in the rectangular holes 3, a pair of guide rods 5 fixedly connected between the opposite side walls of the pair of concave sliders 4, a slitting roller 6 connected to the pair of guide rods 5 through a set locking component, a first square block 7 fixedly connected to both ends of the slitting roller 6, and a square groove 8 opened on the side wall of the first square block 7; and an absorption component, which is set at the horizontal bottom of the first concave frame 2 for absorbing dust.

[0023] During operation, the locking component can be locked into the square grooves 8 opened in the first square blocks 7 at both ends of the slitting roller 6, thus completing the locking of the slitting roller 6. This facilitates disassembly and installation, and solves the problem that in the existing technology, the slitting roller 6 used in traditional slitting mechanisms is generally fixed with bolts, which makes disassembly and replacement cumbersome. During disassembly, it is necessary to loosen and tighten these bolts one by one, which affects work efficiency.

[0024] The positioning assembly includes a pair of support rods 9 fixed to the top of a pair of concave sliders 4, a second concave frame 10 fixed to the top of the pair of support rods 9, and the second concave frame 10 fixed to the bottom of the first concave frame 2 via a pair of electric push rods. A first motor 11 is fixed to the bottom of the second concave frame 10, and a drive rod 12 is provided at the output end of the first motor 11.

[0025] An isosceles block 13 is fixedly attached to the bottom of the drive rod 12. Both ends of the top of the isosceles block 13 are rotatably connected to a connecting rod 14 via a first rotating shaft. The end of the connecting rod 14 away from the isosceles block 13 is rotatably connected to a rectangular block 15 via a second rotating shaft. A support block 16 is fixedly attached to the bottom of the rectangular block 15. The support block 16 is slidably connected to the guide rod 5 through a pair of rectangular holes 3.

[0026] A rotating rod 17 is rotatably connected to the support block 16 through a rotating hole. A second square block 18 is fixed to one end of the rotating rod 17. A second motor 19 is fixed to the side wall of one of the pair of support blocks 16 through a pair of L-shaped rods. The output end of the second motor 19 is connected to the rotating rod 17 for driving.

[0027] During operation, the first motor 11 drives the drive rod 12 to rotate, which in turn drives the isosceles block 13 to rotate. The connecting rod 14 pulls the rectangular block 15 and the support block 16 to move, thereby enabling the rotating rod 17, which is rotatably connected to the support block 16, to move. The second square block 18 is then locked in the square groove 8 of the first square block 7, thus fixing the slitting roller 6. The second motor 19 can also drive the rotating rod 17 to rotate, causing the slitting roller 6 to rotate.

[0028] The absorption assembly includes a collection box 20 fixed to the bottom of the first concave frame 2. A vacuum pump 21 is installed on the collection box 20. The suction end of the vacuum pump 21 is connected to a suction nozzle 22 through a hose, and the suction nozzle 22 is fixed to the bottom of the support rod 9 through a set of first fixing rods.

[0029] During operation, the design of vacuum pump 21 and suction nozzle 22 can effectively absorb dust and fibers generated during the slitting process, reduce dust and fiber pollution to the working environment, improve the cleanliness of the working environment, facilitate centralized treatment of dust, and prevent dust from scattering in the working area.

[0030] A rectangular strip 23 is fixed to the bottom of the support rod 9 by a set of second fixing rods, and a set of brushes 24 are fixed to the side of the rectangular strip 23 near the slitting roller 6.

[0031] During operation, the brush 24 cleans the surface of the slitting roller 6, removing fibers or impurities that may adhere to it. This timely cleaning of the slitting roller 6 prevents the accumulation of fibers or impurities from affecting the slitting quality and extends the service life of the slitting roller 6.

[0032] Working principle: The locking component can be locked into the square grooves 8 opened in the first square blocks 7 at both ends of the slitting roller 6, thus completing the locking of the slitting roller 6, which facilitates disassembly and installation. This solves the problem in the existing technology where the slitting roller 6 used in traditional slitting mechanisms is generally fixed with bolts, which makes disassembly and replacement cumbersome. During disassembly, it is necessary to loosen and tighten these bolts one by one, which affects the work efficiency.

[0033] The first motor 11 drives the drive rod 12 to rotate, which in turn drives the isosceles block 13 to rotate. The connecting rod 14 pulls the rectangular block 15 and the support block 16 to move, thereby enabling the rotating rod 17, which is rotatably connected to the support block 16, to move. The second square block 18 is then locked in the square groove 8 of the first square block 7, thus fixing the slitting roller 6. The second motor 19 can also drive the rotating rod 17 to rotate, causing the slitting roller 6 to rotate.

[0034] The design of vacuum pump 21 and suction nozzle 22 can effectively absorb dust and fibers generated during the slitting process, reduce dust and fiber pollution to the working environment, improve the cleanliness of the working environment, facilitate centralized dust treatment, and prevent dust from scattering in the working area.

[0035] The brush 24 cleans the surface of the slitting roller 6 during operation, removing fibers or impurities that may adhere to the slitting roller 6. This timely cleaning of the slitting roller 6 surface prevents the accumulation of fibers or impurities from affecting the slitting quality and extends the service life of the slitting roller 6.
