[0035] The non-woven fabric slitting assembly also includes a fixed bracket 13, which is fixedly connected to the surface of the first bracket 2. An electric telescopic rod 14 is fixedly connected to the interior of the fixed bracket 13. The output end of the electric telescopic rod 14 is fixedly connected to a fixed roller connecting frame 18. There are two fixed brackets 13, two electric telescopic rods 14 and two fixed roller connecting frames 18, which are symmetrically arranged on the surfaces of the corresponding first brackets 2. A second through groove 15 is provided on the surfaces of the two first brackets 2. The left and right ends of the slitting knife fixed roller 16 are respectively rotatably connected to the corresponding fixed roller connecting frame 18, and the two ends of the slitting knife fixed roller 16 are respectively slidably connected to the inner walls of the corresponding second through groove 15.

[0036] Two second brackets 3 are fixedly connected to the upper end of the base 1, and a first drive motor 6 is fixedly connected to the surface of the left second bracket 3. The opposite surfaces of the two second brackets 3 are rotatably connected to a first non-woven fabric winding roller 5. The output end of the first drive motor 6 is fixedly connected to the first non-woven fabric winding roller 5, and non-woven fabric is wound on the surface of the first non-woven fabric winding roller 5.

[0037] The opposite surfaces of the two first brackets 2 are rotatably connected with three guide rollers 17, the opposite surfaces of the two first brackets 2 are rotatably connected with a fixed roller 21, an adjusting roller 10 is arranged above the base 1, and the non-woven fabric is wound on the surfaces of the three guide rollers 17, the adjusting roller 10 and the fixed roller 21.

[0038] A fixed rod 7 is fixedly connected to the upper end of the base 1, and a movable rod 11 is slidably connected inside the fixed rod 7. The upper end of the movable rod 11 is fixedly connected to a connecting plate 8. A spring 12 is sleeved on the surface of the movable rod 11, and the upper and lower ends of the spring 12 are respectively fixedly connected to the connecting plate 8 and the fixed rod 7. A first through groove 9 is opened on the surface of the first bracket 2. There are two fixed rods 7, connecting plates 8, first through grooves 9, movable rods 11 and springs 12, which are symmetrically arranged at the upper end of the base 1, and the left and right ends of the adjusting roller 10 are rotatably connected to the corresponding connecting plates 8 respectively.

[0039] Two third brackets 4 are fixedly connected to the upper end of the base 1, and two second non-woven fabric winding rollers 20 are rotatably connected to the opposite surfaces of the two third brackets 4. Two second drive motors 19 are fixedly connected to the surface of the left third bracket 4, and the output ends of the two second drive motors 19 are respectively fixedly connected to the corresponding second non-woven fabric winding rollers 20, and the surfaces of the two second non-woven fabric winding rollers 20 are both wound with non-woven fabrics.

[0040] When using the device, first install the nonwoven fabric to be cut on the device, and wind the nonwoven fabric on the surfaces of the corresponding adjustment roller 10, guide roller 17 and fixed roller 21. Start the electric telescopic rod 14 to drive the fixed roller connecting frame 18 to descend, and the fixed roller connecting frame 18 drives the slitting knife fixed roller 16 to slide on the inner wall of the second through groove 15, so that the nonwoven fabric slitting knife 25 contacts the surface of the nonwoven fabric, and the cut nonwoven fabrics are respectively wound on the surface of the corresponding second nonwoven fabric winding roller 20.

[0041] At the same time, the first drive motor 6 is started to drive the first non-woven fabric winding roller to rotate, and the second drive motor 19 is started to drive the corresponding second non-woven fabric winding roller 20 to rotate, so as to convey and cut the non-woven fabric. The non-woven fabric drives the adjusting roller 10, the guide roller 17 and the fixed roller 21 to rotate. Since the non-woven fabric slitting knife 25 is in contact with the non-woven fabric, the non-woven fabric drives the non-woven fabric slitting knife 25 to rotate, and then drives the slitting knife fixed roller 16 to rotate, so as to facilitate the slitting of the non-woven fabric.

[0042] Since the first non-woven winding roller 5 and the two second non-woven winding rollers 20 will cause a certain tension in the non-woven fabric during the slitting process, when the tension of the non-woven fabric is too large, the non-woven fabric will be tightened, and a certain squeezing force will be generated on the adjusting roller 10, the guide roller 17 and the fixed roller 21 during the tightening process. Since the guide roller 17 and the fixed roller 21 are both rotatably connected to the first bracket 2, they can only rotate but cannot move. At this time, the tension of the non-woven fabric will be released from the adjusting roller 10, so that the non-woven fabric drives the adjusting roller 10 to slide inside the first through groove 9, and the adjusting roller 10 drives the connecting plate 8 to move, and the connecting plate 8 drives the movable rod 11 to slide inside the corresponding fixed rod 7, and the connecting plate 8 stretches the spring 12 to relieve the tension of the non-woven fabric.

[0043] When the tension of the non-woven fabric is too small, the spring 12 pulls the connecting plate 8 through the elastic force of the spring 12 itself, and the connecting plate 8 drives the movable rod 11 to slide inside the corresponding fixed rod 7. The connecting plate 8 drives the adjusting roller 10 to slide inside the first through groove 9, and the adjusting roller 10 descends to increase the tension of the non-woven fabric, thereby facilitating the slitting of the non-woven fabric.

[0044] Sometimes it is necessary to use this device to cut non-woven fabrics into different specifications. At this time, it is only necessary to release the gas inside the airbag 22 from the airbag inflation port 23. In the process of deflating the airbag 22, the airbag 22 will shrink. In the process of shrinking, the airbag 22 will drive the protrusion 24 to shrink, so that the protrusion 24 is separated from the corresponding non-woven fabric slitting knife 25, which is convenient for the non-woven fabric slitting knife 25 to slide on the surface of the slitting knife fixing roller 16, and it is convenient to adjust the spacing of the non-woven fabric slitting knife 25. When the spacing of multiple non-woven fabric slitting knives 25 is adjusted to the appropriate specification, use an inflation device to inflate the airbag inflation port 23 to expand the airbag 22 and make the protrusion 24 contact with the corresponding non-woven fabric slitting knife 25 to fix the non-woven fabric slitting knife 25.

[0045] Furthermore, by inflating and deflating the airbag 22, the protrusion 24 can fix and release the non-woven fabric slitting knife 25, adjust the spacing of the non-woven fabric slitting knife 25, cut non-woven fabrics of different specifications, and cut non-woven fabrics multiple times at the same time, thereby improving the flexibility of the device, improving the production efficiency of non-woven fabrics, and improving the practicality of the device.

[0046] By setting the adjusting roller 10 and the spring 12, it is convenient to adjust the tension of the non-woven fabric, prevent the tension of the non-woven fabric from being too large or too small, and prevent the non-woven fabric from being deformed or curled during the slitting process, which will affect the dimensional accuracy and appearance quality of the non-woven fabric and cause the quality of the non-woven fabric to decline during slitting, thereby improving the production efficiency of the device and the product quality of the non-woven fabric.

[0047] Working principle: When using the device, first install the non-woven fabric to be cut on the device, and wind the non-woven fabric on the surfaces of the corresponding adjustment roller 10, guide roller 17 and fixed roller 21. Start the electric telescopic rod 14 to drive the fixed roller connecting frame 18 to descend, and the fixed roller connecting frame 18 drives the slitting knife fixed roller 16 to slide on the inner wall of the second through groove 15, so that the non-woven fabric slitting knife 25 contacts the surface of the non-woven fabric, and the cut non-woven fabrics are respectively wound on the surface of the corresponding second non-woven fabric winding roller 20.

[0048] At the same time, the first drive motor 6 is started to drive the first non-woven fabric winding roller to rotate, and the second drive motor 19 is started to drive the corresponding second non-woven fabric winding roller 20 to rotate, so as to convey and cut the non-woven fabric. The non-woven fabric drives the adjusting roller 10, the guide roller 17 and the fixed roller 21 to rotate. Since the non-woven fabric slitting knife 25 is in contact with the non-woven fabric, the non-woven fabric drives the non-woven fabric slitting knife 25 to rotate, and then drives the slitting knife fixed roller 16 to rotate, so as to facilitate the slitting of the non-woven fabric.

[0049] Since the first non-woven winding roller 5 and the two second non-woven winding rollers 20 will cause a certain tension in the non-woven fabric during the slitting process, when the tension of the non-woven fabric is too large, the non-woven fabric will be tightened, and a certain squeezing force will be generated on the adjusting roller 10, the guide roller 17 and the fixed roller 21 during the tightening process. Since the guide roller 17 and the fixed roller 21 are both rotatably connected to the first bracket 2, they can only rotate but cannot move. At this time, the tension of the non-woven fabric will be released from the adjusting roller 10, so that the non-woven fabric drives the adjusting roller 10 to slide inside the first through groove 9, and the adjusting roller 10 drives the connecting plate 8 to move, and the connecting plate 8 drives the movable rod 11 to slide inside the corresponding fixed rod 7, and the connecting plate 8 stretches the spring 12 to relieve the tension of the non-woven fabric.

[0050] When the tension of the non-woven fabric is too small, the spring 12 pulls the connecting plate 8 through the elastic force of the spring 12 itself, and the connecting plate 8 drives the movable rod 11 to slide inside the corresponding fixed rod 7. The connecting plate 8 drives the adjusting roller 10 to slide inside the first through groove 9, and the adjusting roller 10 descends to increase the tension of the non-woven fabric, thereby facilitating the slitting of the non-woven fabric.

[0051] Sometimes it is necessary to use this device to cut non-woven fabrics into different specifications. At this time, it is only necessary to release the gas inside the airbag 22 from the airbag inflation port 23. In the process of deflating the airbag 22, the airbag 22 will shrink. In the process of shrinking, the airbag 22 will drive the protrusion 24 to shrink, so that the protrusion 24 is separated from the corresponding non-woven fabric slitting knife 25, which is convenient for the non-woven fabric slitting knife 25 to slide on the surface of the slitting knife fixing roller 16, and it is convenient to adjust the spacing of the non-woven fabric slitting knife 25. When the spacing of multiple non-woven fabric slitting knives 25 is adjusted to the appropriate specification, use an inflation device to inflate the airbag inflation port 23 to expand the airbag 22 and make the protrusion 24 contact with the corresponding non-woven fabric slitting knife 25 to fix the non-woven fabric slitting knife 25.

[0052] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
