At the same time, it is equipped with a sample pretreatment process, and finally realizes the quantitative detection of key indicators such as fatigue life and fatigue strength decay law of texturized network wire, providing data support for material research and development, production quality control and application scenario adaptation.

[0004] However, traditional fatigue testing and processing devices for texturized network yarns can only perform endurance tests on a single texturized network yarn, resulting in low testing efficiency. Furthermore, the fixing frame has the potential risk of loosening, low adaptability, and safety hazards. Therefore, a fatigue testing and processing device for texturized network yarns is proposed to solve the above problems. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a fatigue resistance testing and processing device for textured network yarn, comprising a connecting seat 1, wherein a fixing gripping mechanism 2 is provided on the surface of the connecting seat 1; The fixed gripping mechanism 2 includes a motor 21, which is the power source for the entire mechanism. A threaded rod 23 is fixedly connected to the output shaft of the motor 21. When the output shaft of the motor 21 starts rotating, it synchronously drives the threaded rod 23, which is fixedly connected to the surface, to rotate. A connecting rod a22 is fixedly connected to the surface of the motor 21 and is fixedly connected to the outer sidewall of the connecting seat 1. The connecting rod a22 supports and fixes the motor 21, preventing the motor 21 from rotating synchronously with the output shaft. The connecting seat 1 provides fixed support for the connecting rod a22. A connecting rod b24 is slidably connected to the outer sidewall of the connecting seat 1. The connecting rod b24 is threadedly connected to the surface of the threaded rod 23. When the threaded rod 23 rotates, it synchronously drives the threaded rod b24 to rotate. The connecting rod b24 slides left and right on the surface of its threaded rod 23. A sliding rod 25 is slidably connected to the inner wall of the connecting rod b24. The function of the sliding rod 25 is that during endurance testing, the two sets of fixed gripping mechanisms 2 will move towards each other or away from each other. When they move towards each other, they can slide on the inner wall of the connecting rod b24. A sliding block 29 is fixedly connected to the end of the sliding rod 25 away from the connecting rod b24. The left and right movement of the sliding rod 25 will synchronously drive the sliding block 29 to move and clamp the wire. A sliding groove is opened on the surface of the connecting seat 1. A protrusion is provided at the bottom of the sliding block 29. The sliding block 29 is slidably connected in the sliding groove of the connecting seat 1. The function of the sliding groove on the surface of the connecting seat 1 is to limit and guide the sliding block 29, so that the sliding block 29 can only slide along the sliding groove on the surface of the connecting seat 1.

[0020] Reference Figure 2 - Figure 4The fixed block 26 is fixedly connected to the surface of the connecting seat 1. The upper end of the sliding block 29 is fixedly connected to the sliding seat 210. When the sliding block 29 slides, it will synchronously drive the upper fixedly connected sliding seat 210 to slide. The sliding seat 210 is elastically connected to the pressing block 212 through the spring 211. One end of the spring 211 is fixedly connected to the pressing block 212, and the other end of the spring 211 is fixedly connected to the outer side wall of the sliding seat 210. The function of the spring 211 is to automatically reset the pressed block 212 after it has moved. The inner wall of the sliding seat 210 is provided with a sliding groove. The pressing block 212 is slidably connected in the sliding groove of the sliding seat 210. The function of the sliding groove of the sliding seat 210 is to limit and guide the pressing block 212, so that the pressing block 212 can only slide along the sliding groove of the sliding seat 210. The outer side wall of the fixed block 26 is fixedly connected to the winding wheel 28. The winding wheel 28 is in contact with the inner side wall of the sliding block 29. The function of the winding wheel 28 is to wind the textured network yarn to fix its surface tension. The surface of the pressing block 212 contacts the clamping block 27. By pressing the pressing block 212 and the clamping block 27 towards each other, the texturized network wire is clamped, solving the problem that traditional equipment can only clamp a single texturized network wire. Multiple sets can be clamped at the same time. The bottom end of the clamping block 27 is fixedly connected to the fixing block 26. The movement of the fixing block 26 will synchronously drive the clamping block 27 to move. The surface of the sliding block 29 is fixedly connected to the connecting plate 213. The connecting plate 213 supports and fixes the sliding block 29. The surface of the connecting plate 213 is provided with a sliding groove. The surface of the sliding block 29 is provided with a protrusion. The sliding block 29 is slidably connected in the sliding groove of the connecting plate 213. The function of the sliding groove of the connecting plate 213 is to limit and guide the sliding block 29, so that the sliding block 29 can only slide along the sliding groove on the surface of the connecting plate 213. The surface of the fixing block 26 is fixedly connected to the surface of the connecting plate 213. The up and down movement of the connecting plate 213 will synchronously drive the fixing block 26 on the surface to slide up and down. The surface of the connecting seat 1 is provided with a protective mechanism 3.

[0021] Reference Figure 2 - Figure 4The protective mechanism 3 includes a connecting block 31, which is fixedly connected to the outer sidewall of the connecting rod b24. The connecting rod b24 slides along the surface of the threaded rod 23, which synchronously drives the connecting block 31 to move synchronously. A hinge rod 32 is hinged to the upper end of the connecting block 31. The movement of the connecting block 31 will synchronously pull the hinge rod 32 to move up and down. A fixed seat 33 is hinged to the end of the hinge rod 32 away from the connecting block 31. The up and down movement of the hinge rod 32 will synchronously drive the fixed seat 33 to move up and down. The outer sidewall of the fixed seat 33 is fixedly connected to... The protective cover 34 is moved up and down synchronously by the fixing seat 33. The protective cover 34 can be lowered while the textured mesh wire is clamped and fixed, which can effectively prevent accidental breakage and accidental injury caused by the splashing of textured mesh wire during endurance side testing. The surface of the connecting seat 1 is provided with a sliding groove, and the protective cover 34 is slidably connected in the sliding groove of the connecting seat 1. The function of the sliding groove of the connecting seat 1 is to limit and guide the protective cover 34, so that the protective cover 34 can only slide along the direction of the sliding groove of the connecting seat 1.

[0022] Working principle: First, the texturized mesh wire is wound around the surface of the winding wheel 28 for initial fixation. Then, the motor 21 is started, and the output shaft of the motor 21 drives the threaded rod 23 to rotate. The upper and lower sets of sliding blocks 29 are connected to the sliding rod 25 through the connecting rod b24, and the upper and lower sets of fixed blocks 26 are connected to the sliding rod 25 through the connecting rod a22. When the threaded rod 23 rotates, the connecting rod b24 threaded to its surface slides on the surface of the threaded rod 23, synchronously driving the other set of sliding blocks 29 at the upper end to move. The sliding blocks 29 and the fixed blocks 26 move towards each other to initially clamp and fix the texturized mesh wire. The upper sliding seat 210 of the sliding block 29 is slidably connected to the squeezing block 212 through the spring 211 in the sliding groove of the sliding seat 210 and contacts the clamping block 27. With the winding wheel 28 on the outside of the fixed block 26 contacting the inside of the sliding block 29, it can adapt to different sizes of texturized mesh wire. In the reciprocating motion, it completes the stable clamping of the texturized mesh wire and the fatigue resistance test actions such as repeated stretching and bending.

[0023] At the same time, the connecting block 31 on the outside of the connecting rod b24 will move synchronously. The movement of the connecting block 31 will drive the hinge rod 32, which is hinged to it, to slide up and down. The hinge rod 32 will drive the protective cover 34 on the fixed seat 33 to slide up and down. This will prevent the fragments of the broken wire from causing injury to the staff during fatigue testing, effectively reducing the risk of safety accidents. At the same time, it can isolate external impurities, reduce the corrosion of external impurities on the components, extend the service life of the equipment, and prevent external airflow and foreign objects from interfering with the clamping and stretching state of the texturized wire, ensuring accurate and reliable test data.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
