[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model. Example

[0023] Reference Figures 1-4This utility model provides a tensioning mechanism for a counter for a high-speed wool finishing machine, including a wool finishing machine body 1 and a front control console 2. Multiple workstations are arranged above the wool finishing machine body 1. The front control console 2 is located on the feeding side of the wool finishing machine body 1. A wire inlet rod 3 is fixedly connected to the bottom of the front control console 2 at a position corresponding to one of the workstations. A wire inlet ring 4 is provided at the end of each wire inlet rod 3 away from the front control console 2. A counter body 6 is located below the front control console 2 at a position corresponding to one of the wire inlet rods 3. A control panel 15 is located in the middle of the front control console 2 on the side of the counter body 6. A wire stop post 9 is fixedly connected to the top of the front control console 2 above the counter body 6. The diameter of the sensing end of the counter body 6 corresponds to the diameter of the wire stop post 9. A wire stop post 9 is fixed at the top of the front control console 2 at a position corresponding to the wire stop post 9. A fixed base 10 is connected to the yarn. Each fixed base 10 has a yarn outlet groove 11 on its side. A yarn breakage sensor 12 is installed below the yarn outlet groove 11 on the fixed base 10. Each yarn breakage sensor 12 is electrically connected to a corresponding control panel 15. The sensor can detect the yarn breakage and automatically stop the winding when the yarn breaks. A pulley bracket 13 is fixedly connected to the bottom of the fixed base 10. A guide wheel 14 is rotatably connected to the bottom of the pulley bracket 13 at a position corresponding to the yarn outlet groove 11. A guide bar is fixedly connected to the top of the front control panel 2 at a position corresponding to multiple workstations. The guide wheel 14 is aligned with the middle position of the guide bar. When the yarn is wound on the yarn roller, after exiting the guide wheel 14, the yarn will move laterally along the guide bar as the winding roller rotates, which can ensure the stability of the yarn inlet pitch angle.

[0024] The front-end control console 2 has guide rods 5 fixedly connected between the infeed rod 3 and the main body 6 of the counter. The front-end control console 2 also has tension rods 7 fixedly connected between the main body 6 of the counter and the guide post 9. By making the yarn path bend, the component force of the yarn on the sensing end is increased, and the yarn is better tightened on the sensing end of the main body 6 of the counter by the yarn tension. A ceramic cam 8 is set on the outer side of the tension rod 7, and a return torsion spring is set on the inner side of the ceramic cam 8. The inner side of the ceramic cam 8 is elastically rotatably connected to the tension rod 7 through the return torsion spring. The return torsion spring is a spring plate that passes through the tension rod 7. The stabilizing convex direction of the ceramic cam 8 is obliquely upward, which corresponds to the upward infeed direction of the yarn, reducing the infeed resistance. By setting the tension rod 7 between the main body 6 of the counter and the guide post 9, in conjunction with the ceramic cam 8 and the return torsion spring, the elasticity of the return torsion spring can also be used to buffer the yarn tension fluctuation through the torsion of the ceramic cam 8, reducing the probability of yarn suspension and thus improving the accuracy of yarn length recording. Example

[0025] The difference between this embodiment and Embodiment 1 is that the tension rod 7 does not have a ceramic cam 8, but ceramic sleeves are provided on the outside of both the tension rod 7 and the guide rod 5. By setting the tension rod 7 and the guide rod 5 on both sides of the meter counter body 6, the yarn path is made tortuous, and the friction between the yarn and the guide rod 5 is reduced. The yarn is better tensioned on the sensing end of the meter counter body 6 by its own tension. At the same time, the structure is simpler and easier to modify.

[0026] Working principle: In actual operation, the yarn first passes through the infeed ring 4 and then passes in a wavy, zigzag pattern around the guide rod 5, the counter body 6, the tension rod 7, and the stop post 8. By setting the tension rod 7 between the counter body 6 and the stop post 9, the yarn tension can be better secured to the sensing end of the counter body 6. In conjunction with the ceramic cam 8 and the return torsion spring, the elasticity of the return torsion spring can also buffer the yarn tension fluctuations by deflecting or rebounding the ceramic cam 8 under pressure, reducing the probability of the yarn being suspended and ensuring that the yarn is always attached to the sensing end of the counter body 6, thereby improving the accuracy of yarn length recording.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
