[0027] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0028] like Figures 1-10 As shown, the nonwoven fabric slitting device provided in this embodiment includes a base plate 1 and a housing 2 mounted on the base plate 1. A support platform 4 is mounted on the top of one end of the base plate 1, and a first transmission mechanism 3 is mounted on the side of the support platform 4. The support platform 4 supports a take-up shaft 5, which is placed on the support platform 4 and the first transmission mechanism 3. A groove for placing a raw material roller 7 is opened at one end of the base plate 1, and a second transmission mechanism 8 is mounted below the groove. The second transmission mechanism 8 drives the raw material roller 7 to rotate. The take-up shaft 5 and the slitting mechanism 1 are mounted on the top of the base plate 1 from left to right. 2 and tension detector 13. Inside the housing 2, two support rollers 11 are installed. The two support rollers 11 are located on the outside of the slitting mechanism 12 and the tension detector 13, respectively, to support the conveyed nonwoven fabric. The support rollers 11 can guide the nonwoven fabric, which is convenient for the tension detector 13 to detect the tension of the nonwoven fabric. The slitting mechanism 12 divides the nonwoven fabric. The slitting mechanism 12 includes a slitting shaft driven by a drive motor. Multiple slitting blades 18 are installed on the slitting shaft. By rotating the slitting blades 18, the nonwoven fabric can be cut quickly.

[0029] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, two take-up shafts 5 are installed above the first transmission mechanism 3. A drive roller 17 is installed at one end of the take-up shaft 5, and a bearing seat 16 is rotatably installed on the outside of the drive roller 17. The take-up shaft 5 is clamped to the support platform 4 by the drive roller 17. If necessary, the drive roller 17 can also be fixed by bolts to increase the stability during rotation. Multiple rotating shafts 15 are installed inside the first transmission mechanism 3. The multiple rotating shafts 15 are arranged in a triangle. A drive belt 14 is installed on the rotating shaft 15. One of the rotating shafts 15 is driven by a motor, and the remaining rotating shafts 15 are... Driven by the transmission belt 14, the transmission roller 17 rotates and contacts the transmission belt 14. The transmission belt 14 drives the transmission roller 17 to rotate. Multiple limit blocks 10 are elastically installed on the outer side of the take-up shaft 5. The take-up sleeve 6 is put on the take-up shaft 5. When putting it on, the take-up sleeve 6 is put on by pressing the limit block 10. After it is put on, the limit blocks 10 pop out to limit the two sides of the take-up sleeve 6 to prevent excessive shaking during rotation and make it more stable. The first transmission mechanism 3 is provided with a pressure roller 9, which is used to limit the transmission belt 14.

[0030] In this embodiment, as Figure 9 and Figure 10 As shown, the slitting blade 18 includes a support part and a cutting part. The support part is mounted on the slitting mechanism 12. Multiple support parts can be connected to each other on the slitting mechanism 12 by screws. Multiple cutting parts are mounted on the top of the support part. Each cutting part includes multiple cutting components mounted around the support part. Each cutting component includes two brackets 19 mounted opposite each other on the support part. A slitting wire 20 is installed between the two brackets 19. When rotating, the non-woven fabric is cut by the fine slitting wire 20. At the same time, the top of the bracket 19 is also sharpened to facilitate cutting the non-woven fabric. The bracket 19 is fixedly connected to the support part by screws for easy disassembly and replacement.

[0031] In this embodiment, as Figures 1-10 As shown, the working process of the nonwoven fabric fixed-distance slitting device provided in this embodiment is as follows:

[0032] Step 1: Place the raw material roller 7 into the groove on the housing 2, and make one end of the raw material roller 7 contact the second transmission mechanism 8. Adjust the distance between multiple slitting blades on the slitting mechanism 12 to cut non-woven fabrics of different widths. Fit multiple take-up sleeves 6 onto the take-up shaft 5. Fix and limit the take-up shaft 5 by the limiting block 10.

[0033] Step 2: Then, one end of the nonwoven fabric on the raw material roller 7 passes through the support roller 11 and the tension detector 13, and is cut by the slitting mechanism 12 and connected to the two take-up shafts 5 respectively. The cut nonwoven fabric is wound onto the take-up shafts 5. After winding, the take-up shaft 5 is lifted, and the wound take-up sleeve 6 is removed. When removing it, the limit block 10 needs to be pressed to slide the take-up sleeve 6 down.

[0034] In summary, in this embodiment, the nonwoven fabric fixed-distance slitting device of this embodiment has multiple limiting blocks 10 elastically provided on the take-up shaft 5, which facilitates the installation of the take-up sleeve 6 onto the take-up shaft 5 and can fix and limit the take-up sleeve 6 through the limiting blocks 10, thereby increasing the stability of the take-up sleeve 6 during use. By providing the slitting blade 18, since the cutting blade is prone to wear after long-term cutting during use and it is inconvenient to replace the cutting blade, the slitting blade 18 can be used to easily replace the cutting blade.
