Description

Technical Field

[0001] This utility model relates to the field of softness testing technology, specifically a softness testing mechanism for the production of ultra-soft yarn. Background Technology

[0002] Super-soft yarn is a low-twist specialty yarn spun using special spinning equipment and processes. Its twist is 20%–30% lower than conventional yarns, resulting in characteristics such as fluffy yarn, soft hand feel, low fuzz, high strength, and uniform yarn evenness. Fabrics made from it possess skin-friendly, moisture-wicking, breathable, warm, and pill-resistant properties, and are widely used in high-end apparel, home textiles, and industrial textiles. The core function of softness testing in super-soft yarn production is to quantitatively evaluate yarn softness performance, guide process optimization, ensure product quality stability, and meet the functional requirements of end-use applications. However, traditional testing methods suffer from tension fluctuations caused by traction, which can lead to yarn stretching or loosening, altering the internal fiber arrangement and affecting softness test results. For example, stretched yarn may become stiffer, resulting in lower test values. Furthermore, manual tension adjustment suffers from poor repeatability and significant fluctuations in test data between different batches. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, this utility model is a softness testing mechanism for the production of ultra-soft yarn, including a base 1 and a testing machine body 2. The top of the base 1 is provided with a pitch adjustment unit 3. The pitch adjustment unit 3 includes a motor 31 fixedly connected to the top of the base 1, two support bars 32, and a converter shaft 33 rotatably connected to the top of the base 1. The motor 31 is a servo geared motor, which can precisely control the speed and rotation angle of the output shaft. By precisely controlling the output shaft, the accuracy of pitch adjustment can be ensured, preventing excessive force from damaging the soft yarn material. At the same time, its output shaft has a reverse function, and reverse rotation can adjust the pitch in the opposite direction. Furthermore, its output shaft has a locking function, and locking the output shaft can ensure stability. The motor 31 is electrically connected to an external power supply and is controlled by an external program. A first gear 34 is fixedly connected to the surface of the output shaft of motor 31. A second gear 35 and a rotating disk 36 are fixedly connected to the surface of the adapter shaft 33. Two transmission bars 37 are rotatably connected to the rotating disk 36. Sliding blocks 38 are rotatably connected to both transmission bars 37. Connecting rods 39 are fixedly connected to the top of both sliding blocks 38. Clamping and traction components 310 are provided on the top of both connecting rods 39. Guide rods 311 are fixedly connected between the inner walls of the two support bars 32. Through the pitch adjustment unit 3, the soft yarn can be precisely stretched, and its tension can be controlled and adjusted to keep the tension fluctuation within a certain range. This ensures that the yarn is in a stable stretched state during testing, prevents the yarn from being stretched or loosened, and ensures the accuracy of the softness test.

[0022] The left clamping and traction assembly 310 includes a connecting seat 3101 fixedly connected to the top of the left connecting rod 39. A rotating shaft 3102 is rotatably connected to the top of the connecting seat 3101. A fixing clamp 3103 is fixedly connected to the top of the connecting seat 3101. A yarn winding roller 3104 is fixedly connected to the surface of the rotating shaft 3102. A limit rod 3105 is fixedly connected to the top of the fixing clamp 3103. A bolt 3106 is rotatably connected to the top of the fixing clamp 3103. A moving clamp 3107 is slidably connected to the surface of the guide rod 311. The moving clamp 3107 and the bolt 3106 are threadedly connected. The inner wall of the moving clamp 3107 has a threaded groove that matches the bolt 3106. The clamping and traction assembly 310 can wind and clamp the soft yarn, fixing it in place and preventing it from loosening or falling off.

[0023] The top of the base 1 is fixedly connected to four support columns 4 and two support seats 5 respectively. A workbench 6 is fixedly connected between the tops of the two support seats 5. An opening 7 is provided through the workbench 6.

[0024] A top plate 8 is fixedly connected between the tops of the four support columns 4. A hydraulic telescopic rod 9 is fixedly connected to the bottom of the top plate 8. The hydraulic telescopic rod 9 can precisely control the extension and retraction length of the output shaft. The hydraulic telescopic rod 9 is electrically connected to an external power supply and is controlled by an external program. The testing machine body 2 is fixedly connected to the output end of the hydraulic telescopic rod 9. The testing machine body 2 is the core instrument used to evaluate the softness of ultra-soft yarn. It quantifies the softness by measuring the bending resistance and friction of the yarn under pressure. It is responsible for the actual measurement and evaluation of the softness of ultra-soft yarn. Through the measurement of the testing machine body 2, the softness data of ultra-soft yarn can be obtained, and then it can be determined whether it meets the production requirements. This is existing technology and will not be elaborated on in this article. The testing machine body 2 is electrically connected to an external power supply and is controlled by an external program.

[0025] The first gear 34 and the second gear 35 mesh together, and the transmission ratio between the first gear 34 and the second gear 35 is 5 to 1. The first gear 34 drives the second gear 35 to move, which can further improve the accuracy of the adjustment. Both sliding blocks 38 are slidably connected to the guide rod 311.

[0026] The two clamping and traction components 310 have the same structure and are symmetrically distributed on the top of the two connecting rods 39. The soft yarn is fixed by the cooperation of the two clamping and traction components 310.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The working principle of this utility model is as follows: First, the two ends of the soft yarn are wrapped around two yarn-winding rollers 3104. Then, two bolts 3106 are tightened to drive two moving clamps 3107 to move downward on the surface of two limit rods 3105, so that the two moving clamps 3107 clamp the two ends of the soft yarn. Then, the motor 31 is started, which drives the first gear 34 to rotate through the output shaft. When the first gear 34 rotates, it drives the second gear 35, which rotates on the base 1 through the adapter shaft 33. When the adapter shaft 33 rotates, it drives the rotating disk 36 to rotate synchronously. When the rotating disk 36 rotates, it drives two sliding blocks 38 to move to opposite sides on the surface of the guide rod 311 through two transmission bars 37, so as to pull and stretch the clamped soft yarn and adjust and control its tension. Then, the hydraulic telescopic rod 9 is started, so that its output shaft extends and drives the detection machine body 2 at the output end to move downward. Finally, the detection machine body 2 is started to test the softness of the soft yarn.
