[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0022] See Figure 1-4 This utility model provides an adjustable yarn guide device for a spinning machine, including a first guide plate 3 and a second guide plate 4. The first guide plate 3 is located on the right side of the second guide plate 4, and both the first guide plate 3 and the second guide plate 4 are located on the front side of a mounting plate 1. A left electric cylinder 11 and a right electric cylinder 12 are fixed on the back of the mounting plate 1, respectively. The left electric cylinder 11 is connected to the second guide plate 4, and the right electric cylinder 12 is connected to the first guide plate 3. A guide tube 2 is connected to the right side of the first guide plate 3, and a guide wheel 8 is connected to the left side of the first guide plate 4.
[0023] Two sets of steering arms 7 are rotatably connected to the mounting plate 1, and one end of a pneumatic rod 6 is fixedly connected to the outer end of the steering arm. The other end of the pneumatic rod 6 is rotatably connected to a steering wheel 5.
[0024] The mounting plate 1 has a sliding groove 14, and two sliding blocks 13 are slidably connected to the sliding groove 14. The two sliding blocks 13 are fixedly connected to the wire guide plate 3 and the wire guide plate 4 respectively. The left electric cylinder 11 is fixedly connected to the wire guide plate 4 through the sliding block 13, and the right electric cylinder 12 is fixedly connected to the wire guide plate 3 through the sliding block 13. The operation of the left electric cylinder 11 can drive the wire guide plate 4 to move left and right, and the operation of the right electric cylinder 12 can drive the wire guide plate 3 to move left and right.
[0025] Guided grooves 15 are provided on the upper and lower sides of both guide plate 3 and guide plate 4 to facilitate the guiding of the spinning filament bundle.
[0026] The right side of the guide plate 3 is fixedly connected to the guide tube 2 via a connecting rod, enabling the two sets of spinning filament bundles to be combined through the guide tube 2.
[0027] The front and rear sides of the guide plate 4 are fixedly connected with brackets 9. The brackets 9 have a V-shaped structure, and guide wheels 8 are rotatably connected to both ends on the left side of the brackets 9, so as to guide the two sets of spinning filaments.
[0028] A servo motor 10 is fixedly connected to the back of the mounting plate 1. The output shaft of the servo motor 10 passes through the mounting plate 1 and is fixedly connected to the steering arm 7. The operation of the servo motor 10 can drive the steering arm 7 to rotate, thereby adjusting the steering wheel 5 and adjusting the moving pressure of the spinning filament bundle.
[0029] Two sets of steering arms 7 are symmetrically arranged on the left side of the guide plate 4. The two sets of steering arms 7 and the steering wheels 5 on them can be used to turn and guide the two sets of spinning filaments.
[0030] In use, the spun yarn bundles to be twisted and compounded are removed from the spinning machine and pass around two sets of steering wheels 5. The yarn bundles then sequentially pass through guide wheels 8, guide plates 4, guide plates 3, and guide tubes 2. The two yarn bundles are then twisted and compounded together by ring spinning to form composite yarns. During the transport of the yarn bundles, a pressure detection mechanism installed on the mounting plate 1 detects the pressure during the movement of the yarn bundles and controls the servo motor 10 and the left electric cylinder 11. The operation of the left electric cylinder 11 can drive the spinning plate 2 to move left or right, thereby driving the spinning wheels to move synchronously. This allows for the control of the two yarn bundles. The servo motor 10 drives the steering arm 7 to rotate, which in turn drives the pneumatic rod 6 and steering wheel 5 to rotate, thereby adjusting the transport pressure of the spinning filaments. This achieves dynamic adjustment of the spinning filament pressure through the synchronous operation of the steering arm 7 and the pneumatic rod 6, ensuring that the operating pressure of the spinning filaments is controlled within a certain range. Then, the operation of the right electric cylinder 12 can drive the spinning plate 1 to move to the left or right, which in turn drives the guide tube 2 to move synchronously. By adjusting the distance between the spinning plate 1 and the spinning plate 2, the two spinning filaments can be effectively combined, ensuring the twisting and compounding stability of the spinning filaments.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
