[0030] Next, the technical solution of a cotton yarn guide roller in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0031] Embodiment 1

[0032] Referring to the accompanying drawings Figures 1 - 4 As shown, a cotton yarn guide roller includes:

[0033] A yarn guide roller body 10, the yarn guide roller body 10 includes two side plates 11, and four yarn guide plates 12 with arc-shaped grooves are slidably arranged between the two side plates 11;

[0034] An adjusting component 20, the adjusting component 20 includes two limiting discs 23 slidably arranged between the four yarn guide plates 12 and a linkage unit penetrating the limiting discs 23. Through the cooperation of the linkage unit and the limiting discs 23, the limiting discs 23 slide closer or farther away to drive the four yarn guide plates 12 to close or expand;

[0035] And a reset component 30 arranged inside the side plate 11 for resetting the yarn guide plate 12.

[0036] Under the action of the reset assembly 30, the inner wall of the yarn guide plate 12 is always attached to the outer side of the limit disc 23. In the initial state, the four yarn guide plates 12 are close to each other. When the diameter of the yarn guide roller body 10 needs to be adjusted, through the cooperation of the linkage unit and the limit disc 23, the limit disc 23 moves away from each other in the arc-shaped grooves formed in the yarn guide plates 12. When the limit disc 23 passes through different positions of the arc-shaped grooves, since the diameter of the limit disc 23 remains unchanged, the four yarn guide plates 12 will be lifted, increasing the distance between the yarn guide plates 12, thereby changing the diameter of the yarn guide roller body 10. It can be adjusted according to actual needs without frequently replacing the entire yarn guide roller body 10, thus reducing the downtime and replacement cost during the production process. Appropriate diameter adjustment helps reduce the wear and damage of the yarn guide roller body 10 and extends its service life.

[0037] The linkage unit includes a bidirectional lead screw 22 rotatably arranged between the two side plates 11. The bidirectional lead screw 22 sequentially penetrates through the two limit discs 23 and is threadedly connected to the two limit discs 23 with opposite threads. A limit rod 24 is fixedly connected between the two side plates 11, and the limit rod 24 sequentially penetrates through the limit discs 23. By rotating the bidirectional lead screw 22, the limit discs 23 threadedly connected to the threads in different rotation directions move away from each other. The limit rod 24 is used to ensure that the limit discs 23 can only move along the direction of the limit rod 24 under the drive of the bidirectional lead screw 22, preventing the limit discs 23 from rotating or shifting during the movement, thereby ensuring the accuracy and stability of the adjustment.

[0038] One end of the bidirectional lead screw 22 penetrates through the side plate 11 and is fixedly connected to a runner 21. A handle is fixedly installed on the outer side of the runner 21. By holding the handle and rotating it, the runner 21 is driven to rotate, thereby transmitting the rotational driving force to the bidirectional lead screw 22 to realize the rotation of the bidirectional lead screw 22.

[0039] The reset assembly 30 includes a chute 31 in an X-shaped structure formed inside the side plate 11. Sliders 32 are fixedly connected to the outer sides of the yarn guide plates 12 and extend into the chute 31 and are slidably connected to the chute 31. Springs 33 are provided on the sides of the sliders 32 away from the bidirectional lead screw 22 and inside the chute 31. When the yarn guide plates 12 move away from each other, the elastic force provided by the springs 33 can help the yarn guide plates 12 maintain stability during the movement. When the yarn guide plates 12 are not subjected to the supporting force provided inside, under the elastic force of the springs 33, the sliders 32 drive the yarn guide plates 12 to approach each other and reset to the initial state with the smallest diameter.

[0040] An anti-static layer 13 is provided on the outer side of the yarn guide plate 12. The main function of the anti-static layer 13 is to prevent the accumulation of static electricity from causing adverse effects on the yarn guide plate 12 and its surrounding environment. In industries such as textiles, static electricity may cause problems such as yarn entanglement and equipment failures.

[0041] The elastic force of the spring 33 is greater than the sum of the gravity of the yarn guide plate 12 and the frictional force between the yarn guide plate 12 and the side plate 11. This condition indicates that under the action of the spring 33, the yarn guide plate 12 can maintain a stable position and will not slide or move due to its own gravity or the frictional force with the side plate 11.

[0042] As described above, only the preferred specific embodiment of the present utility model is provided, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
