[0018] Please see Figures 1-4In this embodiment of the present invention, a tension-adjustable bobbin includes a housing assembly 1, on which a mandrel assembly 2 is disposed. The housing assembly 1 includes a housing body 11, with a lifting ring 12 for hoisting at the top of the housing body 11, an adjustment knob 13 for adjusting tension on one side of the housing body 11, a front cover 14 installed at the front end of the housing body 11, with a plurality of mounting holes 15 for installation and fixing, and reinforcing ribs 16 for strengthening the structure at the edge of the front cover 14. A bearing 17 for supporting the mandrel assembly 2 and ensuring its smooth rotation is provided inside the housing body 11. The mandrel assembly 2 includes a mandrel body 21, which is connected to the front cover 14 via a connecting flange 22. A rear cover 23 is provided at the rear end of the mandrel body 21, and a support sleeve 24 is fitted on the mandrel body 21. A connecting hole 25 for connecting yarn components is provided at the front end of the mandrel body 21, and an elastic component 26 for tension adjustment is provided between the mandrel body 21 and the support sleeve 24.

[0019] The housing body 11 of the housing assembly 1 provides structural support for the entire spindle. The top lifting ring 12 facilitates the hoisting of the spindle onto the textile equipment. The adjustment knob 13 on one side is used to adjust the yarn tension. The front cover 14 is fixedly installed with the textile equipment or other components through the mounting holes 15 on it. The reinforcing ribs 16 on the edge enhance the structural strength of the front cover 14. The bearing 17 inside the housing body 11 ensures the smooth rotation of the mandrel assembly 2 within the housing. The mandrel body 21 of the mandrel assembly 2 is connected and fixed to the front cover 14 through the connecting flange 22. The rear cover 23 and the support sleeve 24 provide support for the mandrel body 21. The connecting hole 25 at the front end is used to connect yarn conveying related components. The elastic component 26 between the mandrel body 21 and the support sleeve 24 undergoes elastic deformation during tension adjustment, thereby realizing the adjustment of yarn tension.

[0020] The adjustment knob 13 is connected to the tension adjustment mechanism inside the housing body 11 and is used to adjust the compression of the elastic component 26, thereby achieving precise adjustment of the yarn tension.

[0021] The reinforcing rib 16 is made of high-strength alloy material, has a trapezoidal cross section, and is distributed in a ring at equal intervals along the edge of the front cover 14. It can effectively distribute the load of the front cover 14 and greatly improve the deformation resistance of the front cover 14.

[0022] The elastic component 26 is a precision helical compression spring made of fatigue-resistant spring steel with an elastic coefficient in the range of 5-15 N / mm, which can achieve linear and precise adjustment of yarn tension.

[0023] Bearing 17 is a double-row sealed ball bearing. The balls are made of silicon nitride ceramic material and the inside of bearing 17 is filled with high-temperature grease. It has the characteristics of low friction, high wear resistance and long service life, ensuring the smooth rotation of spindle assembly 2 for a long time.

[0024] The mounting holes 15 are arranged in a circular array along the front end cover 14, with a total of eight holes. The hole diameter is compatible with the mounting bolts on the textile equipment, ensuring high reliability of the connection between the spindle and the equipment after installation.

[0025] The outer surface of the adjustment knob 13 is provided with anti-slip teeth. It is made of polyoxymethylene injection molding material, which has both wear resistance and anti-slip properties. Operators can achieve fine adjustment of tension with a precision of 0.1N by rotating the adjustment knob 13.

[0026] The working principle of this utility model is as follows: When it is necessary to adjust the yarn tension, the operator rotates the adjustment knob 13. The adjustment knob 13 drives the tension adjustment mechanism inside the housing body 11 to move, thereby changing the compression degree of the elastic component 26. The change in the elastic force of the elastic component 26 causes a change in the tension of the mandrel assembly 2, thus achieving precise adjustment of the yarn tension. The mandrel assembly 2 rotates within the housing assembly 1 via the bearing 17, ensuring smooth operation of the yarn during conveying. The reinforcing ribs 16 of the front cover 14 effectively enhance the structural strength, reduce deformation and damage during long-term use, and extend the service life of the spindle.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
