[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] like Figure 1-5 As shown, the thread tension adjuster 5 of the embroidery machine in this embodiment includes a screw 51 mounted on the mounting base 1 of the thread clamping assembly, a thread take-up spring 52 with a torsion spring body 521, an adjusting disc 53 for adjusting the torque of the torsion spring body 521, a second thread guide wheel 55, a pressure wheel 56, and an adjusting knob 57. The torsion spring body 521, adjusting disc 53, second thread guide wheel 55, pressure wheel 56, and adjusting knob 57 are sequentially mounted on the screw 51. The torsion spring body 521 is close to the mounting base 1. The adjusting disc 53, second thread guide wheel 55, and pressure wheel 56 can all rotate on the screw 51 and move along the axial direction of the screw 51. The adjusting knob 57 is threadedly engaged with the screw 51. An elastic element 58 is provided between the pressure wheel 56 and the adjusting knob 57. The elastic element 58 is designed as a spring, and its two ends are connected to the pressure wheel 56 and the adjusting knob 57, respectively. A separator 54 is also provided between the adjusting disc 53 and the second guide wheel 55. The separator 54 is rotatably mounted on the screw 51 and can move along the axial direction of the screw 51.

[0041] Reference Figure 6 and Figure 7 One end of the torsion spring body 521 of the thread take-up spring 52 is machined with an outwardly extending crossbar 522, and the other end is machined with an L-shaped locking foot 523. The locking foot 523 engages with the slot of the screw 51 (not shown in the attached figure) for fixation. One end of the crossbar 522 is machined with a thread take-up hook 524, and the thread take-up hook 524 is machined with a thread pass position 525.

[0042] Reference Figure 8 and Figure 9The adjustment disc 53 includes a circular disc body 531 with a notch 5311 machined thereon. An extension portion 5312 extending towards the notch 5311 is also machined on the disc body 531. A first card 533 is machined at one end of the extension portion 5312, extending axially towards the disc body 531. The first card 533 corresponds to the crossbar 522. A second card 534 is also machined on the disc body 531, extending in the same direction as the first card 533.

[0043] Reference Figure 10 and Figure 11 The mounting base 1 has a protruding portion 13 machined on its second arc-shaped surface 12. The protruding portion 13 is cylindrical in shape, and a first boss 131 and a second boss 132 are machined on one end of the protruding portion 13. The protrusion height of the first boss 131 is less than that of the second boss 132. Five first slots 14 are machined on the first boss 131 to mate with the first card 533. These five first slots 14 are evenly arranged along the circumference of the protruding portion 13. During operation, the first card 533 engages with the first slots 14 under the elastic force of the elastic element 58. Five second slots 15 are machined on the second boss 132 to mate with the second card 534. These five second slots 15 are evenly arranged along the circumference of the protruding portion 13. During operation, the second card 534 engages with the second slots 15 under the elastic force of the elastic element 58.

[0044] In this embodiment, when the face thread tension adjuster 5 is installed on the mounting base 1 of the face thread clamp assembly, as follows: Figure 12 and Figure 13 As shown. The mounting base 1 has a first arc-shaped surface 11 and a second arc-shaped surface 12 machined on it. Both the first arc-shaped surface 11 and the second arc-shaped surface 12 are designed as arc surfaces. The first arc-shaped surface 11 is located above the second arc-shaped surface 12, and the radius of the first arc-shaped surface 11 is larger than the radius of the second arc-shaped surface 12. The wire clamp 2 and the first wire guide wheel 3 are mounted on the first arc-shaped surface 11. The wire guide 4 and the surface tension adjuster 5 of this invention are mounted on the second arc-shaped surface 12.

[0045] The working principle of the thread tension adjuster 5 of this utility model is as follows: The operator pulls the adjustment disc 53 outward along the axial direction of the screw 51 by hand, so that the first card 533 and the second card 534 of the adjustment disc 53 disengage from the first slot 14 and the second slot 15. Then, the operator twists the adjustment disc 53. During the twisting process, the first card 533 of the adjustment disc 53 pushes the crossbar 522 of the thread take-up spring 52, thereby twisting the torsion spring body 521 of the thread take-up spring 52 and changing the torque of the torsion spring body 521, adjusting the tension of the thread take-up spring 52, and thus adjusting the tension of the thread of the embroidery machine. When the adjusting disc 53 is rotated into position, the first card 533 and the second card 534 correspond to the other first slot 14 and second slot 15 respectively. Then, the adjusting disc 53 is released, and under the elastic force of the elastic element 58, the adjusting disc 53 slides inward along the axial direction of the screw 51, so that the first card 533 and the second card 534 engage with the first slot 14 and the second slot 15 respectively, thus achieving the positioning of the adjusting disc 53. At this point, the adjustment is complete. Since there are five first slots 14 and second slots 15, the thread tension adjuster 5 of this utility model can achieve five levels of adjustment of the thread tension.

[0046] The advantages of this utility model of thread tension adjuster are: the overall structure is novel and unique, and the operator can adjust the tension of the thread by pulling and twisting the adjustment disc by hand, which is convenient and quick.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
