Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-3 , an anti-winding device of a jacquard machine, comprising a jacquard machine body 1, a placement slot 2, a guide roller 3, a base 4, a support frame 5 and a winding roller 6, a placement slot 2 is opened on one side of the jacquard machine body 1, the inner wall of the placement slot 2 is connected with the guide roller 3 through a fixed shaft sleeve, a base 4 is arranged at intervals on the outer side of the jacquard machine body 1, two groups of support frames 5 are fixedly connected to the top of the base 4, and a winding roller 6 is connected between the two groups of support frames 5 through a rotating shaft sleeve, and also includes:

[0027] An anti-winding structure arranged on the outside of the base 4, which is used to correct the deviation of the cloth;

[0028] The driving structure is arranged on the outside of the jacquard machine body 1, and is used to drive the anti-winding structure to move. The cloth comes out from the weaving part of the jacquard machine body 1, is guided by the placement groove 2 and the guide roller 3, and enters the winding roller 6 for winding.

[0029] Furthermore, the driving structure comprises a cylinder 7, a rack 8, a slider 9 and a gear 11. The outer side of the jacquard machine body 1 is fixedly connected to the cylinder 7 through a fixed block. One end of the cylinder 7 is fixedly connected to the rack 8. The top of the rack 8 is meshed with the gear 11. The bottom of the rack 8 is clamped with the slider 9. When the position of the anti-winding structure needs to be adjusted, the cylinder 7 starts to work, and the telescopic movement of the cylinder 7 drives the rack 8 fixedly connected thereto to perform a linear reciprocating motion. When the rack 8 moves, the linear motion is converted into the rotational motion of the gear 11 through the gear 11 meshed with the top thereof.

[0030] Furthermore, a first U-shaped groove 12 is movably connected to the outer side of the slider 9 , two groups of first connection holes 13 are opened on both sides of the first U-shaped groove 12 , and a second U-shaped groove 14 is fixedly connected to the bottom inner wall of the first U-shaped groove 12 .

[0031] Furthermore, an auxiliary plate 15 is fixedly connected to the bottom inner wall of the second U-shaped groove 14, and both ends of the auxiliary plate 15 are fixedly connected to the two side inner walls of the first U-shaped groove 12. Two groups of third U-shaped grooves 16 are clamped on the outer side of the auxiliary plate 15, and the bottoms of the two groups of third U-shaped grooves 16 are movably connected to the bottom inner wall of the second U-shaped groove 14.

[0032] Furthermore, two groups of auxiliary blocks 23 are fixedly connected to the tops of the two groups of third U-shaped grooves 16, and second connecting holes 10 are opened on the outer sides of the two groups of auxiliary blocks 23. When the bidirectional threaded rod 17 rotates, since it is a bidirectional thread, the auxiliary blocks 23 and the third U-shaped grooves 16 will move in opposite directions on the auxiliary plate 15 respectively, so that the distance of the entire anti-winding structure can be adjusted.

[0033] Furthermore, a bidirectional threaded rod 17 is inserted into the inner walls of the second connecting hole 10 and the first connecting hole 13, and one end of the bidirectional threaded rod 17 is fixedly connected to the outer side of the gear 11 through the connecting rod, and the outer side of the gear 11 is fixedly connected to one end of the bidirectional threaded rod 17 through the connecting rod. In this way, the rotational movement of the gear 11 is transmitted to the bidirectional threaded rod 17 through the connecting rod, causing it to rotate, and the bidirectional threaded rod 17 is inserted into the first connecting hole 13 and the second connecting hole 10 at the same time.

[0034] Furthermore, the anti-winding structure includes a guide block 18, a guide chute 19, a first magnetic block 20, a second magnetic block 21 and a spring 22.

The bottom of the spring 22 is fixedly connected to the first magnetic block 20. The guide chute 19 on the guide block 18 is used to guide the conveying direction of the cloth. When the cloth deviates during the conveying process and contacts the side of the guide chute 19, the first magnetic block 20 The magnetic force between the first magnetic block 20 and the second magnetic block 21 will try to pull the cloth back to the correct position. If the cloth is thin, the first magnetic block 20 will be easier to move under the action of the magnetic force, and the magnetic force between the first magnetic block 20 and the second magnetic block 21 will be relatively weak, but still sufficient to slightly correct the cloth. If the cloth is thick, the first magnetic block 20 will compress the spring 22 after contacting the cloth and move downward along the guide groove 19. At this time, the magnetic force between the first magnetic block 20 and the second magnetic block 21 will be enhanced to provide a greater correcting force. The degree of compression of the spring 22 depends on the thickness of the cloth, so it can adapt to cloth of different thicknesses and ensure the suitability of the correcting force.

[0035] Working principle:

[0036] The cloth comes out of the weaving part of the jacquard machine body 1, passes through the placement groove 2 and the guide roller 3, and enters the winding roller 6 for winding; when the position of the anti-winding structure needs to be adjusted, the cylinder 7 starts to work, and the telescopic movement of the cylinder 7 drives the rack 8 fixedly connected to it to perform linear reciprocating motion. When the rack 8 moves, it converts the linear motion into the rotational motion of the gear 11 through the gear 11 meshing with its top. The outer side of the gear 11 is fixedly connected to one end of the bidirectional threaded rod 17 through a connecting rod, so that the rotational motion of the gear 11 is transmitted to the bidirectional threaded rod 17 through the connecting rod, so that it rotates. The bidirectional threaded rod 17 is inserted into the first connecting hole 13 and the second connecting hole 10 at the same time. When the bidirectional threaded rod 17 rotates, since it is a bidirectional thread, the auxiliary block 23 and the third U-shaped groove 16 will move in opposite directions on the auxiliary plate 15 respectively, so that the entire The anti-winding structure can adjust the distance to adapt to cloths of different widths; the guide bevel 19 on the guide block 18 is used to guide the conveying direction of the cloth. When the cloth deviates during the conveying process and contacts the side of the guide bevel 19, the magnetic force of the first magnetic block 20 and the second magnetic block 21 will try to pull the cloth back to the correct position. If the cloth is thinner, the first magnetic block 20 will be easier to move under the action of the magnetic force, and the magnetic force between the first magnetic block 20 and the second magnetic block 21 will be relatively weak, but still sufficient to slightly correct the cloth. If the cloth is thicker, the first magnetic block 20 will compress the spring 22 after contacting the cloth and move downward along the guide bevel 19. At this time, the magnetic force between the first magnetic block 20 and the second magnetic block 21 will be enhanced to provide a greater correcting force. The degree of compression of the spring 22 depends on the thickness of the cloth, so it can adapt to cloths of different thicknesses and ensure the suitability of the correcting force.
