DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-11, a non-woven fabric slitting device includes a support shaft 1, the outer side of the support shaft 1 is sequentially sleeved with three cutters 2, and the spacing between two adjacent cutters 2 is the same, the support shaft 1 is provided with two openings 3, and the positions of the openings 3 are respectively located between two adjacent cutters 2, and the parts of the support shaft 1 located between the two adjacent cutters 2 are provided with connecting grooves 4, and a connecting shaft 5 is provided in the connecting groove 4. The two ends of the bottom side of the connecting shaft 5 are respectively fixedly installed with a clamping plate 6, and a clamping slot 7 for the clamping plate 6 to pass through is provided in the support shaft 1. The bottom of the clamping plate 6 passes through and extends to the bottom of the clamping slot 7, and limit plates 8 are respectively fixedly installed on both sides of the bottom of the support shaft 1, and the clamping plate 6 and the clamping plate 6, the clamping plate 6 and the limit plate 8 are respectively attached to the two side surfaces of the cutter 2, and the clamping plate 6, the limit plate 8 and the cutter 2 are respectively provided with connected screw holes 9, and a fastening bolt 10 is screwed in the screw hole 9, and a fastening nut 11 is screwed in the outer side of the fastening bolt 10.

[0030] In the above embodiment, when it is necessary to disassemble and replace the cutter 2, the cutter 2, the connecting shaft 5 and the clamping plate 6 are unfastened by loosening the fastening bolts 10 and the fastening nuts 11, and then the connecting shaft 5 and the clamping plate 6 are removed, and the cutter 2 is slid along the trajectory of the support shaft 1 to remove the cutter 2 from the position of the opening 3. Then, the replaced cutter 2 is inserted into the support shaft 1 until one side of the cutter 2 is blocked by the clamping plate 6 or the limit plate 8, so that the connecting shaft 5 and the clamping plate 6 are respectively inserted into the connecting groove 4 and the clamping groove 7, and the fastening bolts 10 are screwed into the screw holes 9 and locked with the fastening nuts 11. The cutter 2 can be disassembled and replaced quickly and conveniently.

[0031] Specifically, the driving shaft 12 and the rotating shaft 13 are fixedly mounted on both ends of the support shaft 1 respectively. The side of the driving shaft 12 away from the support shaft 1 is fixedly mounted on the output end of the driving motor 23, and the driving motor 23 is mounted on the driving motor mounting seat 24.

[0032] In the above embodiment, the driving motor 23 is used as a driving force to rotate the driving shaft 12, thereby driving the support shaft 1 and the cutter 2 to rotate.

[0033] Specifically, a workbench 14 is provided below the support shaft 1, a support plate 15 is fixedly installed on the top of the workbench 14, a bearing mounting hole is provided in the support plate 15, a bearing 16 is fixedly installed in the bearing mounting hole, and the side of the rotating shaft 13 away from the support shaft 1 is sleeved in the inner ring of the bearing 16.

[0034] In the above embodiment, the bearing 16 is used to limit the rotation of the rotating shaft 13 , and the friction force when the rotating shaft 13 rotates can be reduced.

[0035] Specifically, a reserved hole 17 for the cutter 2 to pass through is provided in the workbench 1 .

[0036] In the above embodiment, the function of the reserved hole 17 is to allow the portion below the cutter 2 to pass through the workbench 1 smoothly.

[0037] Specifically, three groups of limiting rollers 18 are respectively provided on both sides of the cutter 2 , and the non-woven fabric 22 passes through between each group of limiting rollers 18 in sequence.

[0038] In the above embodiment, the limiting roller 18 is used to limit the moving track of the non-woven fabric 22 to prevent it from deviating.

[0039] Specifically, six groups of fixed plates 19 are fixedly installed on the workbench 14 , and two ends of each group of limiting rollers 18 are fixedly installed on the side of each group of fixed plates 19 that are close to each other.

[0040] In the above embodiment, the limiting roller 18 is installed and fixed by the fixing plate 19 .

[0041] Specifically, support legs 20 are fixedly installed around the bottom of the workbench 1, and a reinforcing rod 21 is fixedly installed between two adjacent support legs 20.

[0042] In the above embodiment, the bottom of the workbench 1 is supported on all sides by the support legs 20 , and the reinforcing rods 21 further increase the connection firmness between two adjacent support legs 20 .

[0043] Working principle: When in use, the non-woven fabric 22 is passed through the limiting rollers 18 on both sides of the cutter 2 in turn, and the non-woven fabric 22 is gradually moved by the traction device (not shown in the figure). During this process, the drive motor 23 drives the drive shaft 12 to rotate. While the drive shaft 12 rotates, the support shaft 1, the cutter 2, the connecting shaft 5, the clamping plate 6, the limiting plate 8, the fastening bolt 10, the fastening nut 11 and the rotating shaft 13 rotate synchronously. At this time, the rotating cutter 2 will cut the non-woven fabric 22, so that the original complete non-woven fabric 22 is cut into four non-woven fabrics 22, thereby realizing the slitting of the non-woven fabric 22.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
