In addition, when the tension adjustment operation is performed, the yarn is prone to break due to uneven instantaneous stress due to the lack of buffer design, causing waste of raw materials and reducing production efficiency. In view of this, it is urgent to develop a textile yarn frame with simple structure, convenient and accurate tension adjustment, and buffer effect during adjustment to meet the development needs of modern textile industry.

[0025] The right inner wall of the installation groove 201 is fixedly installed with a stepping motor 13 through a mounting bracket 12, the output shaft of the stepping motor 13 is rotatably penetrated to the left side of the mounting bracket 12 and fixedly sleeved with a gear 14, the bottom end of the stand 3 is fixedly connected with a toothed rod 15, the toothed rod 15 is provided with a tooth groove 151, and the gear 14 is engaged with the tooth groove 151 on the toothed rod 15; the stand 3 is provided with a buffer cavity 301, and the bottom end of the buffer support 4 is movably sleeved in the buffer cavity 301, and a buffer spring 302 is further fixedly connected between the bottom end of the buffer support 4 and the bottom inner wall of the buffer cavity 301; a pressure sensor 11 is further arranged between the top end of the buffer support 4 and the yarn wheel frame 5.

[0026] In the embodiment, the left side of the yarn frame main part 2 is fixedly installed with an electric telescopic rod 9, the output end of the electric telescopic rod 9 is movably penetrated into the installation groove 201 and fixedly sleeved with a positioning block 901, the left side of the toothed rod 15 is fixedly provided with an anti-skid layer 902, and the positioning block 901 is positioned and matched with the anti-skid layer 902.

[0027] In the embodiment, the left side of the mounting base 1 is provided with a recess, and a controller 10 is arranged in the recess, the controller 10 controls the work of the electric telescopic rod 9 and the stepping motor 13 according to the information sensed by the pressure sensor 11.

[0028] In the embodiment, the bottom of each side of the stand 3 is provided with a first sliding block 16, the inner walls of both sides of the installation groove 201 are provided with first sliding grooves, and the first sliding blocks 16 are slidably installed in the first sliding grooves in the vertical direction; the bottom of each side of the buffer support 4 is provided with a second sliding block 303, the inner walls of both sides of the buffer cavity 301 are provided with second sliding grooves, and the second sliding blocks 303 are slidably installed in the second sliding grooves in the vertical direction.

[0029] The mounting bracket 12 is specifically a U-shaped structure, the mounting bracket 12 is provided with a bearing, and the output shaft of the stepping motor 13 is rotatably installed on the bearing.

[0030] As Figures 1-4The adjustable tension yarn frame shown allows for tension adjustment of the yarn conveyed on the first guide wheel 6 by raising and lowering the yarn wheel frame 5 and the first guide wheel 6. Specifically, during adjustment, the retraction of the output end of the electric telescopic rod 9 moves the positioning block 901 to the left, releasing the positioning block 901 from the anti-slip layer 902 and the gear 15. Subsequently, the output shaft of the stepper motor 13 drives the gear 14 to rotate forward or backward. When the gear 14 rotates, it meshes with the tooth groove 151 on the gear 15, thereby moving the gear 15 upward or downward for adjustment. When the rack 15 moves, it also drives the column 3, buffer support 4, yarn wheel frame 5, and first guide wheel 6 to rise and fall, thereby adjusting the tension of the textile yarn transmitted on the first guide wheel 6 (i.e., when the first guide wheel 6 moves up, the tension of the textile yarn is loosened, and vice versa). Furthermore, during the tension adjustment process, the compression and buffering of the buffer spring 302 can prevent the textile yarn tension from being adjusted too tightly due to excessive rise and fall of the first guide wheel 6, thus providing a good buffering effect and reducing the occurrence of yarn breakage. Furthermore, during tension adjustment, the controller 10 also controls the extension and retraction of the electric telescopic rod 9 and the forward and reverse rotation of the stepper motor 13 based on the information sensed by the pressure sensor 11. In this way, when the tension of the textile yarn is adjusted too tightly, the controller 10 can automatically control the operation of the stepper motor 13, thereby automatically driving the first guide wheel 6 to adjust up and down, so that the height of the first guide wheel 6 can better adapt to the tension requirements of the textile yarn. This avoids the problem that existing textile yarn frames can only make rough adjustments during tension adjustment, which is difficult to meet the needs of subtle changes in yarn tension, thus leading to unstable product quality and increased defect rate. In addition, it also has a good buffering function in tension adjustment, preventing the yarn from breaking easily due to uneven instantaneous force, resulting in waste of raw materials, which greatly meets the development needs of modern textile industry.

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.
