[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] like Figure 1 It is a structural schematic diagram of the utility model, a slitting device for non-woven fabric production, comprising a frame 1, a feeding mechanism 2 and a slitting mechanism 3, the feeding mechanism 2 is arranged on the frame 1, the feeding mechanism 2 is used to transport the non-woven fabric to the slitting mechanism 3, the slitting mechanism 3 is installed on the frame 1, and the slitting mechanism 3 is used to cut the non-woven fabric;

[0020] like Figure 2 , Figure 3 As shown, the slitting mechanism 3 includes a mounting seat 31, a driving member 32, a screw rod 33, a movable seat 34 and a slitting tool 35. The end of the mounting seat 31 is fixedly connected to the frame 1, and there is a gap between the mounting seat 31 and the frame 1 for non-woven fabric to pass through. The driving member 32 is fixedly connected to the mounting seat 31, and the screw rod 33 is rotatably connected to the mounting seat 31. The driving member 32 is a motor, and the output end of the driving member 32 is transmission-connected to the input end of the screw rod 33. The driving member 32 is used to provide power for the rotation of the screw rod 33 The movable seat 34 and the screw rod 33 are threadedly connected, and the slitting tool 35 is installed on the movable seat 34. Both ends of the slitting tool 35 have slitting edges 351. Through the design of the slitting tool 35 that cuts horizontally along the width direction of the non-woven fabric, the non-woven fabric can be completely cut off, thereby improving the slitting efficiency. Through the design of the screw rod 33 and the slitting tool 35 with slitting edges 351 on both sides, the reciprocating slitting motion of the slitting tool 35 is realized, thereby reducing the resetting process of the slitting tool 35 and improving the slitting efficiency.

[0021] like Figure 4 As shown, the slitting blade 351 of the slitting tool 35 is in a V-shaped structure, which can prevent the free cloth from slipping off the slitting tool 35.

[0022] like Figure 2 , Figure 3As shown, the slitting mechanism 3 also includes a slider 36, a slide rail 37 matching the slider 36, and a connecting seat 38. The slide rail 37 is fixedly connected to the mounting seat 31. The extension direction of the slide rail 37 is the same as the extension direction of the screw rod 33, so that the movement directions of the slider 36 and the movable seat 34 are the same, ensuring the synchronous movement of the two. The slider 36 and the slide rail 37 are slidably connected. The slider 36 is fixedly connected to the movable seat 34 through a connecting plate 39. The connecting plate 39 is used to connect the slider 36 and the movable seat 34 in series. The connecting seat 38 and the slider 36 are fixedly connected. The slitting tool 35 is installed on the connecting seat 38. The cooperation between the slider 36 and the slide rail 37 makes the movement of the slitting tool 35 more stable.

[0023] like Figure 4 As shown, the connection seat 38 and the connection plate 39 are fixedly connected to increase the installation stability of the connection seat 38.

[0024] like Figure 1 , Figure 2 As shown, the screw rod 33 extends along the width direction of the non-woven fabric to achieve transverse slitting of the non-woven fabric.

[0025] Working principle: When in use, the driving member 32 starts to rotate forward, causing the screw rod 33 to rotate, driving the slitting tool 35 to move to complete the slitting of the non-woven fabric, and the feeding mechanism 2 starts to continue to convey the non-woven fabric until the required slitting length is reached. The driving member 32 starts to rotate in the reverse direction, causing the screw rod 33 to rotate in the opposite direction, driving the slitting tool 35 to reset, and during the resetting process, the slitting of the non-woven fabric is completed.

[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
