Technical Field
[0001] This utility model relates to the field of textile equipment, and in particular to a yarn tensioning device for an embroidery machine. Background Technology
[0002] An embroidery machine is a machine used to replace manual embroidery, weaving textile yarns into various patterns according to a predetermined path.
[0003] During the operation of an embroidery machine, stable yarn transmission is a crucial prerequisite for ensuring stable operation. If the yarn tension is too low during transmission, it may cause yarn tangling, affecting transmission and potentially leading to abnormal equipment operation. Typically, the problem of low yarn tension during transmission is solved by adding a tensioning structure along the yarn's transmission path to increase yarn tension.
[0004] Currently, tensioning structures, such as tensioning wheels and tensioning rollers, adjust their tension primarily by adjusting the angle of the connecting rod connected to the structure. However, the angle of this connecting rod is currently fixed by a fixing screw. Although this positioning structure provides stable positioning, the fixing screw needs to be removed during adjustment, making the adjustment process cumbersome.
[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with the drawings and examples, and it should be understood that the specific examples described herein are only used to explain the utility model and not used to limit the utility model.
[0021] Referring to Figure 1 , the utility model provides a kind of embroidery machine yarn tensioning device, which includes the tensioner of yarn transmission path setting, and the tensioner includes tensioner housing 5, the tensioning part 1 (the tensioning part is wheel structure or roll structure, for example, tensioning roller is shown in the figure) contacted with yarn and angle adjusting structure connected with it by support rod 3;The tensioner housing 5 is fixedly installed on textile frame 00;When the tensioning degree of tensioning part 1 is adjusted, only the angle of support rod 3 needs to be adjusted (in the angle adjusting process, support rod 3 will rotate around fixed point, so that the distance H between tensioning part 1 and the transmission path of textile yarn increases), to increase the tensioning degree of it (textile yarn).
[0022] Preferably, a plurality of tensioning parts 1 can be arranged on the same tensioner housing 5 to realize the tensioning work of a plurality of textile yarns, and it should be noted that the tensioning degree of each group of yarns is different, so the tensioning parts 1 are independently adjusted.
[0023] Referring to Figure 2 , Figure 4 and Figure 5 , the angle adjusting structure includes adjusting disc 2 connected with support rod 3, locking disc 4 capable of being attached to the end face of adjusting disc 2 and realizing the angle locking of adjusting disc 2, and distance adjusting assembly adjusting the distance between adjusting disc 2 and locking disc 4;Cooperative positioning structure is arranged on the attachable end face of locking disc 4 and adjusting disc 2;
[0024] When support rod 3 needs to be angle adjusted, there is a gap between the cooperative end faces of locking disc 4 and adjusting disc 2, and at this time, adjusting disc 2 is in angle active state. And when the angle adjustment of support rod 3 is completed, the end faces of locking disc 4 and adjusting disc 2 are reattached after the control of distance adjusting assembly, and the cooperative positioning structure cooperates to realize the angle locking of adjusting disc 2.
[0025] The matching positioning structure is a convex block 21 arranged around the locking disc 4 and the adjusting disc 2; the convex blocks 21 have a matching gap between them. After the end faces of the locking disc 4 and the adjusting disc 2 are attached to each other, the convex block 21 of the locking disc 4 is inserted into the adjusting disc 2 and located in the matching gap between the convex blocks 21. Through the clamping positioning between the convex blocks 21, the rotation angle locking of the adjusting disc 2 is realized.
[0026] In order to facilitate adjustment, the convex block 21 is a bevel convex block with a slope.
[0027] Referring to Figure 2 and Figure 3 , the side end of the adjusting disc 2 is connected to the tensioner housing 5 through a spring 7. One end of the spring 7 is fixedly connected to the tensioner housing 5, and the other end is fixedly connected to the adjusting disc 2. The spring 7 not only provides movement support for the adjusting disc 2 in the direction close to the locking disc 4, but also provides rotation torque support.
[0028] The distance adjustment assembly is a moving shaft 6 arranged in the tensioner housing 5 and having a threaded end. The end of the moving shaft is screwed to the tensioner housing 5. The locking disc 4 is fixedly installed on the moving shaft 6 (the moving shaft 6 can be provided with multiple sets of locking discs 4 along the axial direction thereof).
[0029] When the support rod 3 is adjusted in angle, the adjusting disc 2 is attached to the locking disc 4 under the elastic support of the spring 7 during adjustment (at this time, the end faces of the locking disc 4 and the adjusting disc 2 are attached to each other). During the rotation of the support rod 3, the matching bevel convex blocks play a similar “ratchet” effect (realize one-way locking).
[0030] When the support rod 3 needs to be reset in angle, the moving shaft 6 needs to be rotated to move the locking disc 4, so that the locking disc 4 is separated from the maximum support range of the adjusting disc 2 by the spring 7. After there is enough gap between the locking disc 4 and the adjusting disc 2, the adjusting disc 2 is reset by the torsion of the spring 7.
[0031] It needs to be noted that the torsional force of the spring 7 is much smaller than the friction force between the threads of the moving shaft 6. That is, the spring 7 with a torsional tendency cannot drive the moving shaft 6 to rotate, so as to ensure the normal operation of the locking structure.
[0032] In conclusion, the utility model provides a kind of embroidery machine yarn tensioner, including being arranged in yarn transmission path's tensioner, this tensioner includes tensioner shell, and the tensioning part (the tensioning part is wheel structure or roll structure) being contacted with yarn and the angle adjusting structure being connected with it by support rod;The tensioner shell is fixedly installed on textile frame;In the tensioning degree adjustment of tensioning part, only the angle of support rod needs to be adjusted (in the angle adjusting process, support rod will rotate around fixed point, so that the distance H between tensioning part and the transmission path of textile yarn increases), to increase the tensioning degree of it (textile yarn).Multiple sets of tensioning parts can be arranged on the same tensioner shell, realize the tensioning work of multiple sets of textile yarn, it needs to be explained that, since the tensioning degree of each set of yarn is different, so multiple sets of tensioning parts are independently adjusted. The utility model can adjust the tensioning degree of textile yarn, in the adjusting process, only need to pull down support rod to the angle required, and it is convenient to adjust.
[0033] Of course, the utility model can also have other various embodiments, without departing from the spirit and essence of the utility model, those skilled in the art can make various corresponding changes and deformation according to the utility model, but these corresponding changes and deformation should all belong to the protection scope of the claims attached to the utility model.
