[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention provides a limit mechanism. When the non-woven fabric is cut according to different width standards, if the circular knife position needs to be adjusted, the rotating frame is pulled, and the rotating frame and the circular plate are fixed by attraction through a magnet. The rotating frame drives the sliding rod to move in the inner cavity of the limit cylinder. When the sliding rod drives the limit rods on both sides to slide, the two limit rods are squeezed against the inner wall edge of the slide groove. Since the depth of the through hole is one third of the height of the limit block, the two limit rods drive the limit block to move relatively, so that the limit block is separated from the through hole, and the circular knife mechanism is released from the limit.

[0015] 2. The present invention provides a circular knife mechanism. When the limit block is separated from the through hole to release the limit on the circular knife, the circular knife is pushed to slide on the sleeve, and the connecting shaft is driven by the circular knife to slide in the installation groove. When the circular knife moves on the sleeve, the arc plate is squeezed with the inner wall of the installation groove, so that the arc plate is separated from the installation hole, so that the circular knife moves on the sleeve. By evenly opening a plurality of installation grooves on the sleeve, the spacing of the circular knives can be adjusted according to the cutting requirements of different required widths, and the circular knives do not need to be adjusted with the help of external tools, so that the distance between the circular knives can be adjusted more quickly, thereby reducing the time for tool change adjustment, thereby improving the processing efficiency of the device.

[0016] 3. The present invention provides a cleaning component. When the sleeve drives the circular knife to rotate, the circular knife cuts the non-woven fabric. When the circular knife rotates, it contacts and rotates with the contact mechanism, so that the contact mechanism can clean the side of the circular knife. At the same time, the impurities that fall down enter the collecting tank through the circular hole. When the inside of the collecting tank is cleaned, the electric hydraulic cylinder is opened so that the output end of the electric hydraulic cylinder drives the extrusion plate to move in the collecting tank through the guide rod, so that the impurities in the collecting tank are discharged through the baffle.

[0017] 4. The present invention provides a contact mechanism. When the circular knife is cutting, the circular knife continuously rotates so that the circular knife contacts the contact ring, so that the contact ring can clean up the waste generated during processing on the side of the circular knife, thereby avoiding the waste generated during the cutting of the non-woven fabric from adhering to the circular knife, thereby interfering with the cutting of the non-woven fabric. At the same time, when the circular knife rotates in the contact housing, the circular knife contacts the grinding block, thereby grinding the cutting edge of the circular knife while the circular knife is cutting, thereby avoiding the circular knife from cutting for a long time and causing wear on the cutting edge, which requires the operator to disassemble and grind the circular knife, thereby reducing the cutting efficiency of the circular knife. By providing multiple elastic rods, excessive squeezing force between the grinding block and the circular knife can be avoided to avoid damage to the circular knife.

[0039] Embodiment 2, use Figure 9-11 The cutting device for a nonwoven fabric slitting machine of the present invention is described as follows:

[0040] like Figure 9-11 It is shown that a cutting device for a nonwoven fabric slitting machine of the present invention is based on the first embodiment;

[0041] The cleaning component 8 includes a collecting plate 81, both sides of which are fixedly connected to the inner wall of the bracket 2, an electric hydraulic cylinder 82 is fixedly connected to the side of the bracket 2, a collecting groove 85 is provided on the side of the collecting plate 81, a baffle 83 is rotatably connected to the inner wall of the collecting groove 85, a contact mechanism 84 is fixedly connected to the inner wall of the collecting plate 81, and circular holes 86 are evenly provided on the side of the collecting plate 81, a guide rod 87 is fixedly connected to the output end of the electric hydraulic cylinder 82, and an extrusion plate 88 is fixedly connected to the other end of the guide rod 87, and the side of the extrusion plate 88 is slidably connected to the inner wall of the collecting groove 85, and scrapers 89 are fixedly connected to both sides of the extrusion plate 88, and the scrapers 89 are away from the extrusion plate One side of 88 contacts the inner wall of the collecting tank 85; when the sleeve 71 drives the circular knife 731 to rotate, the circular knife 731 cuts the non-woven fabric, and the circular knife 731 rotates by contacting with the contact mechanism 84, so that the contact mechanism 84 can clean the side of the circular knife 731, and at the same time, the cleaned impurities enter the collecting tank 85 through the circular hole 86. When the inside of the collecting tank 85 is cleaned, the electric hydraulic cylinder 82 is opened, so that the output end of the electric hydraulic cylinder 82 drives the extrusion plate 88 to move in the collecting tank 85 through the guide rod 87, so that the impurities in the collecting tank 85 are discharged through the baffle 83.

[0042] The contact mechanism 84 includes a contact shell 841, the side of the contact shell 841 is fixedly connected to the inner wall of the collecting plate 81, the side of the contact shell 841 is evenly provided with clearance holes 842, the inner wall of the contact shell 841 is fixedly connected to an elastic rod 843, the other end of the elastic rod 843 is fixedly connected to a contact plate 844, the side of the contact plate 844 is in contact with the inside of the contact shell 841, the side of the contact plate 844 away from the elastic rod 843 is fixedly connected to a grinding block 845, and the inner wall of the contact shell 841 is fixedly connected to a contact ring 846; when the circular knife 731 performs cutting work, the circular knife 731 continuously rotates, so that the circular knife 731 contacts the contact ring 846, so that the contact ring 846 can move the circular knife 731 1. The waste generated during the processing on the side surface of the circular knife 731 is cleaned, so as to avoid the waste generated during the cutting process of the non-woven fabric from adhering to the circular knife 731, thereby interfering with the cutting work of the non-woven fabric. At the same time, when the circular knife 731 rotates in the contact shell 841, the circular knife 731 contacts the grinding block 845, so that when the circular knife 731 is cutting, the cutting edge of the circular knife 731 can be ground, thereby avoiding the circular knife 731 from cutting for a long time and causing wear on the cutting edge, so that the operator needs to disassemble and grind the circular knife 731 to reduce the cutting efficiency of the circular knife 731. By setting a plurality of elastic rods 843, it is avoided that the extrusion force between the grinding block 845 and the circular knife 731 is too large, thereby preventing the circular knife 731 from being damaged.

[0043] The specific workflow is as follows:

[0044] During operation, the non-woven fabric to be cut is manually placed on the second roller 9, and the non-woven fabric is passed through the cutting component 7. The motor 6 is turned on, and the output end of the motor 6 drives the cutting component 7 to rotate in the inner wall of the bracket 2, so that the cutting component 7 cuts the non-woven fabric. At the same time, the non-woven fabric after cutting is wound around the first roller 5 to roll up the cut non-woven fabric. At the same time, when the cutting component 7 is cutting, the cleaning component 8 can clean the cutting component 7 at the same time.

[0045] The output end of the motor 6 drives the sleeve 71 to rotate in the inner cavity of the bracket 2, so that the sleeve 71 drives the circular knife mechanism 73 to cut the non-woven fabric passing through the sleeve 71. When different slitting widths are required for the non-woven fabric, the rotating frame 75 is adjusted to drive the limiting mechanism 76 to move in the inner cavity of the sleeve 71, so that the limiting mechanism 76 adjusts the distance between the circular knife mechanism 73.

[0046] The sleeve 71 is driven by the output end of the motor 6 to rotate in the inner cavity of the bracket 2, and at the same time, the circular knife 731 and the non-woven fabric passing through the sleeve 71 are cut. When the cutting work is performed according to the different width standards for cutting the non-woven fabric, when the position of the circular knife 731 needs to be adjusted, the rotating frame 75 is pulled, and the rotating frame 75 and the circular plate 74 are fixed by attraction through magnets, and the sliding rod 763 is driven by the rotating frame 75 to move in the inner cavity of the limiting cylinder 761. When the sliding rod 763 drives the limiting rods 766 on both sides to slide, the two limiting rods 766 are squeezed with the inner wall edge of the sliding groove 762. Since the depth of the through hole 734 is one-third of the height of the limiting block 767, the two limiting rods 766 drive the limiting block 767 to move relative to each other, so that the limiting block 767 is separated from the through hole 734, and then the circular knife mechanism 73 is released from the limit.

[0047] When the limiting block 767 is separated from the through hole 734 to release the limit of the circular knife 731, the circular knife 731 is pushed to slide on the sleeve 71, and the connecting shaft 732 is driven by the circular knife 731 to slide in the installation groove 72. When the circular knife 731 moves on the sleeve 71, the circular arc plate 736 is squeezed with the inner wall of the installation groove 72, so that the circular arc plate 736 is separated from the installation hole 77, so that the circular knife 731 moves on the sleeve 71. By evenly opening a plurality of installation grooves 72 on the sleeve 71, the spacing of the circular knives 731 can be adjusted according to the cutting requirements of different required widths.

[0048] When the sleeve 71 drives the circular knife 731 to rotate, the circular knife 731 cuts the non-woven fabric. When the circular knife 731 rotates, it contacts and rotates with the contact mechanism 84, so that the contact mechanism 84 can clean the side of the circular knife 731. At the same time, the impurities that fall through the circular hole 86 enter the collection tank 85. When the inside of the collection tank 85 is cleaned, the electric hydraulic cylinder 82 is opened, so that the output end of the electric hydraulic cylinder 82 drives the extrusion plate 88 to move in the collection tank 85 through the guide rod 87, so that the impurities in the collection tank 85 are discharged through the baffle 83.

[0049] When the circular knife 731 is cutting, the circular knife 731 continuously rotates, so that the circular knife 731 contacts the contact ring 846, so that the contact ring 846 can clean up the waste generated during the processing on the side of the circular knife 731, so as to avoid the waste generated during the cutting of the non-woven fabric from adhering to the circular knife 731, thereby interfering with the cutting of the non-woven fabric. At the same time, when the circular knife 731 rotates in the contact shell 841, the circular knife 731 contacts the grinding block 845, so that when the circular knife 731 is cutting, the cutting edge of the circular knife 731 can be grinded, so as to avoid the circular knife 731 from cutting for a long time and wear on the cutting edge, so that the operator needs to disassemble and grind the circular knife 731 to reduce the cutting efficiency of the circular knife 731. By setting a plurality of elastic rods 843, it is avoided that the extrusion force between the grinding block 845 and the circular knife 731 is too large to cause damage to the circular knife 731.

[0050] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
