[0030] The present invention discloses a tension regulator 100, comprising a yarn guide 10, a spring seat 20, a sleeve 30, a first spring 40, a second spring 50, and a third spring 60. The yarn guide 10 is used to contact and guide the yarn, and the spring seat 20 is used to connect the yarn guide 10 and install the three springs. The three springs are arranged in different directions, which can compensate for the tension of the yarn in different directions, realize comprehensive yarn tension adjustment, and provide a rapid response.

[0031] Specifically, please refer to the following: Figures 1 to 3 The yarn guide 10 has a U-shaped fork structure. It includes a first arm 11 and a second arm 12, which are symmetrically arranged to form the U-shaped fork structure. In application, the yarn is positioned within the U-shaped opening of the yarn guide 10, allowing the yarn guide 10 to hold and support it.

[0032] Please refer to the above. Figure 1 , Figure 2 and Figure 4A spring seat 20 is located on the back side of the U-shaped opening of the yarn guide 10. The spring seat 20 includes a hinge portion 21 and a spring rod 22, with the hinge portion 21 hinged to the yarn guide 10. The first end of the spring rod 22 is connected to the hinge portion 21, and the second end of the spring rod 22 extends into the sleeve 30. The first end of a first spring 40 is connected to a first support arm 11, and the second end of the first spring 40 is connected to the hinge portion 21 on one side corresponding to the first support arm 11. The first end of a second spring 50 is connected to a second support arm 12, and the second end of the second spring 50 is connected to the hinge portion 21 on one side corresponding to the second support arm 12. A third spring 60 is sleeved on the spring rod 22, and the third spring 60 is located between the sleeve 30 and the spring rod 22. The first spring 40 and the second spring 50 are symmetrically arranged and can provide tension compensation in two directions. The central axis of the third spring 60 is located between the central axes of the first spring 40 and the second spring 50, and can provide tension compensation in a third direction. The yarn guide 10 can rotate around its hinge axis with the hinge part 21, thereby providing tension compensation at all times during the left and right swing of the yarn.

[0033] Please refer to the above. Figure 1 , Figure 2 and Figure 5 The sleeve 30 has a first channel 31, a second channel 32, and a third channel 33 inside. The second channel 32 connects the first channel 31 and the third channel 33. The structure of the second channel 32 matches the structure of the spring rod 22. The cross-sectional areas of the first channel 31 and the third channel 33 are both larger than the cross-sectional area of ​​the second channel 32. The spring rod 22 passes through the first channel 31, the second channel 32, and the third channel 33. The third spring 60 is located at the first channel 31. It should be noted that the cross-sectional areas of each of the above channels are the areas corresponding to the cross-sections formed by cutting along a direction perpendicular to the central axis of the sleeve 30.

[0034] Furthermore, please refer to [see also] Figures 4 to 6 In a preferred embodiment of the present invention, the cross-section of the spring rod 22 (the cross-section formed by cutting along a direction perpendicular to the length of the spring rod 22) is D-shaped, and the cross-section of the second channel 32 is correspondingly D-shaped. The spring rod 22 passes through the first channel 31, the second channel 32, and the third channel 33. The second channel 32 cooperates with the D-shaped structure of the spring rod 22 to prevent the spring rod 22 from rotating around the central axis of the sleeve 30, that is, to prevent the yarn guide 10 from rotating around the central axis of the sleeve 30, thus ensuring the effectiveness of tension compensation. However, the present invention is not limited thereto. In other embodiments, the anti-rotation function of the spring rod 22 and the second channel 32 can also be achieved by other reasonable adaptation structures.

[0035] Please see Figure 7 , Figure 7This is a schematic diagram of the spring seat in a tension regulator according to another embodiment of the present invention. In another embodiment of the present invention, a limiting plate 23 is provided at the end of the spring rod 22 away from the hinge portion 21. The limiting plate 23 is located within the third channel 33. The axial thickness of the limiting plate 23 is less than the axial length of the third channel 33, and the cross-sectional area of ​​the limiting plate 23 is greater than the cross-sectional area of ​​the second channel 32. In this way, the limiting plate 23 can limit the spring rod 22, prevent the spring rod 22 from dislodging, and ensure the stability of the tension regulator 100.

[0036] In a preferred embodiment of the present invention, the tension regulator 100 further includes a magnetic head 70, which is fixedly disposed at the end of the sleeve 30 away from the hinge portion 21. The magnetic head 70 is used to install the tension regulator 100 onto the textile equipment and facilitates adjustment of the installation position according to actual installation requirements. Of course, the present invention is not limited thereto. In other embodiments, the tension regulator 100 can also adopt other reasonable installation methods, such as using bolts for installation.

[0037] In a preferred embodiment of the present invention, the inner wall of the U-shaped opening of the yarn guide 10 is a smooth convex arc surface, which facilitates the contact and guidance of the yarn and avoids wear on the yarn.

[0038] Please refer to the above. Figures 1 to 4 In one embodiment, the first spring 40 and the second spring 50 are installed using hooks for easy installation, disassembly, and replacement. Specifically, the back of the first support arm 11 is provided with a first hook 111, the back of the second support arm 12 is provided with a second hook 121, and the two sides of the hinge portion 21 are respectively provided with a third hook (not labeled due to obstruction) and a fourth hook 211. The first hook 111 and the second hook 121 are symmetrical, and the third hook and the fourth hook 211 are symmetrical. The first end of the first spring 40 is hooked on the first hook 111, and the second end of the first spring 40 is hooked on the third hook. The first end of the second spring 50 is hooked on the second hook 121, and the second end of the second spring 50 is hooked on the fourth hook 211. However, the present invention is not limited thereto, and in other embodiments, the first spring 40 and the second spring 50 can also adopt other reasonable installation methods.

[0039] In a preferred embodiment of the present invention, a connecting plate 13 is provided on the back side of the U-shaped opening of the yarn guide 10, and the connecting plate 13 is hinged to the hinge portion 21. (See also...) Figures 1 to 3 In one embodiment, the hinge portion 21 has a U-shaped structure, and the connecting plate 13 is located inside the U-shaped structure of the hinge portion 21 and is hinged to the hinge portion 21.

[0040] Furthermore, the central axes of the first spring 40, the second spring 50, and the third spring 60 are in the same plane, and the hinge portion 21 and the hinge axis of the yarn guide 10 are perpendicular to this plane. This ensures the stability of the tension regulator 100 and facilitates comprehensive adjustment and rapid dynamic response.

[0041] According to another aspect of the invention, a textile apparatus is also provided; see below. Figure 8 , Figure 8 This is a schematic diagram of the tension regulator of an embodiment of the present invention applied to a textile machine. The textile machine includes a yarn feeding roller 200, a yarn detector 300, a winding roller 400, and the aforementioned tension regulator 100. The yarn detector 300 is located between the yarn feeding roller 200 and the winding roller 400, and the tension regulator 100 is located between the yarn detector 300 and the winding roller 400. Yarn 500 is drawn from the yarn feeding roller 200, passes through the U-shaped opening of the yarn guide 10 of the yarn detector 300 and the tension regulator 100, and is then wound onto the winding roller 400.

[0042] In the spinning process, yarn 500 swings left and right within the U-shaped opening of yarn guide 10. The three springs of tension regulator 100 provide tension compensation in three directions, dynamically adjusting the tension of yarn 500 to avoid defects such as braided yarn, improving yarn quality and reducing breakage rate. Tension regulator 100 is located between yarn probe 300 and winding roller 400, and the yarn guide 10 adopts a U-shaped fork structure that can encircle the yarn. After yarn splicing, there is no need for yarn hooking, thus improving production efficiency.

[0043] In summary, this invention provides a tension regulator and a textile device using the tension regulator. The tension regulator is equipped with springs in three directions, which can compensate for the tension of the yarn in different directions, achieving comprehensive adjustment and rapid response, thereby improving yarn quality and reducing breakage rate. The tension regulator is located between the yarn probe and the winding roller, and the yarn guide adopts a U-shaped fork structure, which can wrap around the yarn. After the yarn splice is completed, there is no need for yarn hooking operation, which can improve production efficiency.

[0044] The present invention has been described in the above-described embodiments; however, these embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. Conversely, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
