[0027] To clearly illustrate the above embodiment, in an embodiment of the present invention, as Figure 1 and Figure 2 shown, the rotating device 6 may include: a mounting tube 8, a bearing seat 9, a vertical plate 10, a first motor 11, a driving wheel 12, and a driven gear ring 13. The mounting tube 8 is provided on the bearing seat 9. The vertical plate 10 is provided on the bearing seat 9. The first motor 11 is provided on the vertical plate 10. The driving wheel 12 is provided on the driving end of the first motor 11. The driven gear ring 13 is provided on the outer wall of the mounting tube 8. The driving wheel 12 and the driven gear ring 13 are meshed with each other. The first electromagnet 2 is magnetically connected to the mounting tube 8.

[0028] It can be understood that the first motor 11 described in this embodiment can drive the driven gear ring 13 to rotate through the driving wheel 12. The driven gear ring 13 can drive the installation pipe 8 to rotate, and the installation pipe 8 can drive the rotating rod 1 to rotate through the first electromagnet 2.

[0029] Further, a limiting plate 22 is provided on the rotating rod 1. A first limiting sliding groove 23 is opened on the inner wall of the installation pipe 8, and a second limiting sliding groove 24 is opened on the inner wall of the winding pipe 4.

Among them, the first horizontal driving assembly 14 is arranged above the rotating rod 1, the hydraulic telescopic device 15 is arranged on the first horizontal driving assembly 14, and the saw blade cutting machine 16 is arranged at the driving end of the hydraulic telescopic device 15.

[0031] It can be understood that the first horizontal driving assembly 14 described in this embodiment can drive the hydraulic telescopic device 15 to move horizontally. The hydraulic telescopic device 15 can drive the saw blade cutting machine 16 to move vertically, and the saw blade cutting machine 16 can cut the non-woven fabric roll.

[0032] The first horizontal driving assembly 14 may include: a driving bin 17, a second motor 18, a ball screw 19, a ball slider 20, and a connecting plate 21. Among them, the second motor 18 is arranged in the driving bin 17, the ball screw 19 is arranged at the driving end of the second motor 18, the ball slider 20 is arranged on the ball screw 19, and the ball slider 20 is connected to the hydraulic telescopic device 15 through the connecting plate 21.

[0033] It can be understood that the second motor 18 described in this embodiment can drive the ball screw 19 to rotate. The ball slider 20 can move on the rotating ball screw 19, and the ball slider 20 can drive the hydraulic telescopic device 15 to move horizontally through the connecting plate 21.

[0034] Specifically, the first horizontal driving component 14 controls the movement of the saw blade cutting machine 16 to directly above the target cutting area by driving the hydraulic telescopic device 15. The hydraulic telescopic device 15 can drive the saw blade cutting machine 16 to move vertically towards the non-woven fabric. During the process of the saw blade cutting machine 16 cutting the non-woven fabric, the first motor 11 drives the driven gear ring 13 to rotate through the driving wheel 12. The driven gear ring 13 drives the installation pipe 8 to rotate. The rotating installation pipe 8 drives the rotating rod 1 to rotate through the first electromagnet 2, and the rotating rod 1 can also drive the winding pipe 3 to rotate through the first electromagnet 2. Through the self-rotation of the unwinding pipe 4, the saw blade cutting machine 16 can cut the non-woven fabric on the unwinding pipe 4. By freely adjusting the working position of the saw blade cutting machine 16 through the first horizontal driving component 14 and the hydraulic telescopic device 15, the appropriate cutting area can be selected according to requirements, and the cutting width can be adjusted, with high flexibility.

[0035] In an embodiment of the present invention, as Figure 1 、 Figure 5 and Figure 6 shown, it may further include: a rotating rod moving device 26, an electric telescopic rod 29, a connecting rod 30, and a second electromagnet 31. The rotating rod moving device 26 includes: a second horizontal driving component 27 and a fixing ring 28. The fixing ring 28 is arranged on the second horizontal driving component 27. The second horizontal driving component 27 has the same structure as the first horizontal driving component 14 and is configured to drive the rotating rod 1 to move horizontally through the fixing ring 28.

[0036] It can be understood that the fixing ring 28 and the rotating rod 1 are fixedly connected in this embodiment, so that the second horizontal driving component 27 can control the horizontal movement of the rotating rod 1.

[0037] The electric telescopic rod 29 is arranged on the first horizontal driving component 14. One end of the connecting rod 30 is connected to the driving end of the electric telescopic rod 29, and the other end of the connecting rod 30 is connected to the second electromagnet 31. The second electromagnet 31 is detachably connected to the unwinding pipe 4.

[0038] Specifically, during the process of the first horizontal driving component 14 adjusting the saw blade cutting machine 16, the working position of the second electromagnet 31 is synchronously adjusted. The electric telescopic rod 29 can control the second electromagnet 31 to be in contact connection with the unwinding pipe 4 through the connecting rod 30. The second electromagnet 31 can be magnetically connected to the unwinding pipe 4. During the process of the second horizontal driving component 27 driving the rotating rod 1 to move horizontally, the first electromagnet 2 loses magnetism, and the second electromagnet 31 gains magnetism. The adjustment of the second electromagnet 31 in the horizontal direction by the first horizontal driving component 14 and the electric telescopic rod 29 removes the unwinding pipe 4 from the rotating rod 1. After removal, the remaining unwinding pipe 4 is pushed towards the limiting abutting plate 34 and abuts against it through the second electromagnet 31 (in the demagnetized state).
