[0002] The thread clamping assembly of an embroidery machine is used to separate, clamp, and adjust the tension of the embroidery machine's thread.

[0003] Currently, existing embroidery machine thread clamping assemblies, such as the thread clamp for embroidery machines with patent application number 2023112013073 entitled "Embroidery Machine Thread Clamp with Quick Threading and Adjustable Tension," disclose a thread clamping assembly for embroidery machines, and the thread clamp assembly for embroidery machines with patent application number 2012204760645 entitled "Thread Clamp Assembly for Embroidery Machines," also disclose a thread clamping assembly for embroidery machines, both of which have flat mounting panels. The disadvantages of these existing thread clamping assemblies are: 1. When used with a circular embroidery machine head for embroidery work, the rotating head during embroidery can easily cause the thread to become too loose or too tight. 1. It affects the normal embroidery operation of the embroidery machine, making the embroidered products prone to quality defects and reducing the quality of the embroidery products; 2. Because the mounting panel is a flat structure, the lateral dimension of the entire thread clamping assembly is too large, and the overall layout is not compact enough; 3. The thread clamping assembly for the embroidery machine with application number 2012204760645 has a thread guide wheel on it. The protruding component at the thread guide wheel is a thread tension adjuster. The adjusting plate of this thread tension adjuster has an arc groove. The screw rod passes through the arc groove and is threaded to the mounting panel. Twisting the screw loosens the adjusting plate, and then rotating the adjusting plate adjusts the tension of the thread. After adjustment, the screw is tightened to fix the adjusting plate. The adjustment is relatively troublesome. Utility Model Content

[0045] 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.

[0046] like Figure 1-6 As shown, the embroidery machine of this embodiment has a thread clamping assembly, which includes a mounting base 1 with a fan-shaped cross-section and a thread clamping device. The mounting base 1 has a convex arc-shaped surface, and the thread clamping device is disposed on the arc-shaped surface. The thread clamping device includes a thread clamping assembly, a thread guide wheel assembly, and a thread tension adjuster assembly. The thread clamping assembly, the thread guide wheel assembly, and the thread tension adjuster assembly are respectively mounted on the arc-shaped surface. The thread clamping assembly is located above the thread guide wheel assembly, and the thread guide wheel assembly is located above the thread tension adjuster assembly.

[0047] The arc surface is machined with a first arc surface 11 and a second arc surface 12 that are convex. Both the first arc surface 11 and the second arc surface 12 are designed as arc surfaces. One end of the first arc surface 11 is connected to one end of the second arc surface 12. The first arc surface 11 is located above the second arc surface 12. The radius of the first arc surface 11 is larger than the radius of the second arc surface 12.

[0048] The wire clamp assembly and the wire guide roller assembly are respectively disposed on the first arc-shaped surface 11, and the top thread tension adjuster assembly is disposed on the second arc-shaped surface 12. The wire clamp assembly includes nine wire clamps 2, which are evenly arranged along the circumference of the first arc-shaped surface 11. The wire guide roller assembly includes nine first wire guide rollers 3, which are evenly arranged along the circumference of the first arc-shaped surface 11.

[0049] The tension regulator group consists of nine tension regulators 5, which are arranged in two rows. One row of tension regulators 5 is designated as the first row group, and the other row is designated as the second row group. The first row group is located above the second row group. The first row group has four tension regulators 5, and the second row group has five tension regulators 5. The four tension regulators 5 in the first row group are evenly arranged along the circumference of the second arc-shaped surface 12, and the five tension regulators 5 in the second row group are also evenly arranged along the circumference of the second arc-shaped surface 12.

[0050] A wire component 4 is also installed on the second arc-shaped surface 12 of the mounting base 1. (See reference) Figure 18 The conductor 4 has a conductor hole 41 for the surface wire to pass through.

[0051] Reference Figure 9-13 The thread tension adjuster 5 includes a screw 51 mounted on the mounting base 1, a thread-taking 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.

[0052] Reference Figure 16 and Figure 17 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.

[0053] Reference Figure 14 and Figure 15 The 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.

[0054] Reference Figure 7 and Figure 8The 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.

[0055] The working principle of the thread tension adjuster 5 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 can achieve five levels of adjustment of the thread tension.

[0056] The advantages of the thread clamping assembly of this utility model are as follows:

[0057] 1. The mounting base is provided with an arc-shaped surface for mounting the thread guide device. The arc-shaped surface can be designed as a circular arc, so that the multiple thread clamps, thread guide wheels and top thread tension adjusters of the thread guide device can be arranged along the arc direction of the arc-shaped surface. When working with the circular embroidery machine head, the top thread clamping assembly of this utility model can rotate synchronously with the circular embroidery machine head, so that the top thread is not too loose or too tight, ensuring the normal progress of the embroidery work and guaranteeing the quality of the embroidery.

[0058] 2. Because the mounting base has an arc-shaped surface for mounting the wire guide device, the arrangement of each component of the wire clamp assembly is more reasonable and compact, resulting in a more compact overall structure and smaller size of the wire clamp assembly.

[0059] 3. The structure of the tension regulator of the thread clamp assembly of this utility model has been optimized, making the structure of the tension regulator more novel and unique. The operator can adjust the tension of the thread by pulling and twisting the adjustment disc by hand, which is convenient and quick.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
