[0022] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-5 , the present utility model provides a technical solution: a yarn guide for a spinning machine, including: a spinning machine body 1, an installation plate 2 is arranged on the side of the spinning machine body 1, an installation hole 3 is opened on the surface of the installation plate 2, a rotating bearing 4 is arranged at the bottom of the installation plate 2, a tension spring 5 is arranged on the surface of the rotating bearing 4, and a limit nut 6 is arranged at one end of the tension spring 5; a positioning rod 7, a yarn guide plate 8 is arranged on the end surface of the positioning rod 7, a first bearing 9 is arranged in the yarn guide plate 8, a support rod 10 is arranged on the inner ring surface of the first bearing 9, a guide tube 11 is sleeved on the surface of the support rod 10, a guide plate 12 is arranged on the end surface of the guide tube 11, and a limit plate 13 is sleeved on the surface of the guide tube 11;

[0024] First, the spinning yarn 101 is wound around the guide tube 11. The cooperation of the guide plate 12 and the limit plate 13 can guide and direct the spinning yarn 101. When guiding through the guide tube 11, the positioning rod 7 can be supported by the tension spring 5 arranged at the bottom of the installation plate 2. Thus, on the one hand, the guide tube 11 can be used for guiding, and on the other hand, the spinning yarn 101 can be tensioned. The guide tube 11 can rotate in cooperation with the first bearing 9, thereby reducing the friction force on the spinning yarn 101 by rotation and avoiding abrasion of the spinning yarn 101 during yarn guiding.

[0025] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the stable guiding of the spinning yarn 101, a tension spring 5 is provided. Multiple groups of installation holes 3 are opened, and the multiple groups of installation holes 3 are linearly arranged at equal distances on the surface of the installation plate 2. The positioning rod 7 is inserted into the installation hole 3, threads are provided on the surface of the positioning rod 7, and the limit nut 6 is screwed on the positioning rod 7. One end of the tension spring 5 is fixedly connected to the surface of the rotating bearing 4, and the other end of the tension spring 5 is fixedly connected to the surface of the limit nut 6. The yarn guide plate 8 is in a "C"-shaped plate structure, the support rod 10 is fixedly connected to the inner ring surface of the first bearing 9, the guide tube 11 is fixedly connected to the surface of the support rod 10, and the spinning yarn 101 is wound around the guide tube 11;

[0026] In use, the limiting nut 6 can be screwed onto the positioning rod 7. The setting of the rotating bearing 4 can prevent the tension spring 5 from twisting when the limiting nut 6 is rotated. The tension spring 5 can increase the upward thrust of the positioning rod 7, so that the yarn 101 can be tensioned by the upward force of the positioning rod 7. On the other hand, the positioning rod 7 can be installed by the limiting nut 6, and the tension of the yarn 101 can be adjusted by the rotation position of the limiting nut 6.

[0027] Example 3: Based on Example 2, in order to facilitate the guiding of yarns 101 of different thicknesses, a limiting plate 13 is provided. The guide plate 12 has a groove on its surface, and a positioning screw 14 is provided in the groove. The limiting plate 13 has a placement groove 15 on its surface, and a support shaft 16 is provided on the side of the placement groove 15. A protective plate 17 is provided on the surface of the support shaft 16. A limiting hole 18 is provided on the surface of the protective plate 17. The diameter of the limiting hole 18 is larger than the diameter of the positioning screw 14. The protective plate 17 is fitted onto the positioning screw 14 through the limiting hole 18. A fixing nut 19 is screwed onto the surface of the positioning screw 14. The bottom of the protective plate 17 is rounded.

[0028] When it is necessary to guide yarns 101 of different thicknesses during use, the limiting plate 13 can first be moved on the guide tube 11, and then the protective plate 17 is fitted onto the positioning screw 14 through multiple sets of limiting holes 18 on its surface. Then the fixing nut 19 can be tightened to fix the protective plate 17, thereby adjusting the distance between the limiting plate 13 and the protective plate 17 to facilitate the guiding of yarns 101 of different thicknesses. On the other hand, the setting of the protective plate 17 can prevent the yarn 101 from jumping during the guiding process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
