Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to an anti-deviation winding guide device for non-woven fabrics. Background Art

[0002] Nonwoven fabrics, also known as nonwovens, non-woven fabrics, and non-woven fabrics, are made from oriented or randomly arranged fibers through friction, cohesion, bonding, or a combination of these methods. The meaning of "not woven" lies in their inherent "non-woven" nature. Nonwovens exist in the form of fibers, while woven fabrics exist in the form of yarns. This is a key feature that distinguishes nonwovens from other fabrics. Nonwovens cannot be individually pulled out of the fabric. During the nonwoven fabric processing process, winding equipment is required to wind and store the nonwoven fabric.

[0003] Currently, the non-woven fabric winding device mainly uses a reel to wind the non-woven fabric. During the winding process, the position of the non-woven fabric may shift due to various reasons, which will affect the winding efficiency and winding aesthetics of the reel, and will also cause wrinkles in the wound non-woven fabric.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] One end of the non-woven fabric passes through each roller 5 in turn and is fixed on the reel 7. The connecting rod 6 is then used to drive the reel 7 to rotate, and the reel 7 winds the non-woven fabric. When the non-woven fabric is offset, the non-woven fabric will push the detection plate 2 to slightly offset. At this time, the detection plate 2 is reset by the spring and also uses the spring to apply pressure to the corresponding pressure sensor 4. The pressure sensor 4 transmits the pressure data to the controller 8. The controller 8 controls the operation of the adjustment mechanism according to the change in the pressure value, so that the adjustment mechanism drives the reel 7 to push, so that the reel 7 can adapt to the changes in the position of the non-woven fabric.

[0025] like Figure 1 and Figure 2 As shown, a mounting plate 16 is installed on the upper part of the body 1, and one end of the connecting rod 6 is rotatably connected to the axis opened on one side of the mounting plate 16.

[0026] like Figure 1 and Figure 2 As shown, the adjustment mechanism includes a swivel 9 mounted on one end of the reel 7, and the side of the swivel 9 facing away from the reel 7 is rotatably connected to a connecting ring. Two telescopic rods 10 and a hydraulic cylinder 12 are installed between the connecting ring and the mounting plate 16. The telescopic end of the hydraulic cylinder 12 is fixedly connected to one side of the swivel 9. The hydraulic cylinder 12 is mounted on one side of the mounting plate 16 and is located below the connecting rod 6. The swivel 9 is sleeved on the outside of the connecting rod 6. The hydraulic cylinder 12 is drive-connected to the hydraulic pump, and the hydraulic pump is electrically connected to the controller 8.

[0027] The pressure sensor 4 detects the pressure change and transmits the pressure data to the controller 8, which controls the start and stop of the hydraulic cylinder 12. The hydraulic cylinder 12 is used to drive the reel 7 to slide on the connecting rod 6, and at the same time, the reel 7 adapts to the offset position of the non-woven fabric.

[0028] like Figure 2 and Figure 5 As shown, one side of the swivel 9 is fixedly connected to a circumferential array of limit rods 17, and the reel 7 is provided with a limit hole 18 at a corresponding position relative to each limit rod 17, and the limit hole 18 is plugged into the limit rod 17;

A threaded groove 3 is provided at a position corresponding to the threaded hole of the reel 7, and the threaded groove 3 is threadedly connected to the external thread provided on the movable end of the threaded rod 19.

[0031] By rotating the threaded rod 19, the movable end of the threaded rod 19 is threadedly connected to the thread groove 3, thereby fixing the reel 7 on the swivel 9, otherwise the reel 7 is separated.

[0032] like Figure 1 and Figure 2 As shown, a servo motor 13 is installed on the side of the mounting plate 16 facing away from the hydraulic cylinder 12.

The system of the controller 8 adopts the module provided by the corresponding merchant, and this application will not go into details.

[0033] The servo motor 13 is used to drive the connecting rod 6 to rotate. The connecting rod 6 is located in the axial center cavity of the mounting plate 16 and has a cylindrical shape.

[0034] like Figure 3 As shown, the detection plate 2 is located on the inner wall of the groove and is rotatably connected to a bidirectional screw 14. The outer thread of the bidirectional screw 14 is provided with two symmetrically arranged baffles 15. The baffles 15 are provided with perforations at corresponding positions relative to the roller 5. The roller 5 is slidably connected in the perforated cavity.

[0035] By rotating the bidirectional screw 14 , the bidirectional screw 14 drives the two baffles 15 to slide toward each other or in directions opposite to each other, thereby changing the range of movement of the nonwoven fabric on the roller 5 .
