Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of yarn performance detection, in particular to a textile yarn tensile property detection equipment. BACKGROUND

[0002] Yarn is a continuous linear material formed by twisting and holding together of textile fibers, and is the basic raw material of weaving, knitting, rope making and thread making industries. Its quality directly determines the durability, appearance and hand feeling of the final product. In actual application, yarn will be subjected to various forms of tension during production, processing and use, so its tensile property is the core mechanical index for evaluating the quality grade and applicability of yarn. Through scientific and accurate tensile property detection of yarn, not only can key data be provided for product grading and quality control, but also feedback can be provided for guiding the optimization of spinning process, which is of great significance for ensuring the quality of textiles and improving the competitiveness of the industry.

[0003] In the prior art, the detection of yarn tensile property is mostly carried out by using a standardized single yarn strength tester or an electronic universal material testing machine. Such devices usually include a static clamp for fixing the upper end of the yarn sample, a moving clamp for pulling the lower end of the yarn sample, a sensor for measuring the tension, and a control system for recording the displacement and generating the stress-strain curve. The working process is as follows: a sample of a specified length is cut from a yarn package, and the two ends of the sample are fastened to the upper and lower clamps respectively, then the lower clamp is driven to move downward at a constant speed, the yarn is subjected to a tensile load until it breaks, during which the sensor collects force value data in real time, and the system finally calculates the breaking strength and breaking elongation and other results. Among them, the function of the clamp is to prevent the yarn from slipping during the stretching process, the sensor is responsible for converting the physical signal into an electrical signal, and the driving mechanism provides a controllable and uniform stretching speed.

[0004] For the related technology in the above, when the yarn is stretched during the detection process, the diameter will be significantly reduced due to the Poisson effect, and the thinning process will cause the "untwisting" effect, which makes the structure of the test section of the yarn become more and more loose, and the friction between the fibers is weakened. This makes the final measured mechanical property data a coupling result of the inherent property of the yarn material itself and the performance degradation caused by the structure loosening, rather than the inherent property. When the detection result is not ideal, the producer cannot accurately judge whether the problem is caused by the fiber material itself or the unstable twisting structure, thereby bringing uncertainty to process diagnosis. In addition, this detection method of cutting a sample section is a destructive sampling detection, which cannot continuously and non-destructively evaluate the whole roll of yarn, which not only affects the detection efficiency, but also may reduce the overall persuasiveness of the detection result due to insufficient sample representativeness, so improvement is needed. SUMMARY

[0005] To solve the above-mentioned problems, the application provides a textile yarn tensile property detection equipment.

[0006] The application provides a textile yarn tensile property detection equipment, which adopts the following technical scheme: A textile yarn tensile property detection equipment, comprising a mounting table, a first mounting seat and a second mounting seat are arranged on the mounting table, a pay-off reel is arranged on the first mounting seat, a take-up reel is arranged on the second mounting seat, a plurality of groups of yarns pass through the first mounting seat and the second mounting seat, a plurality of groups of rotating discs are arranged on the take-up reel in correspondence with the number of yarn strands, the plurality of groups of rotating discs are arranged in a circumferential array with the center of the take-up reel, a first conveying roller and a second conveying roller are arranged on each of the plurality of groups of rotating discs, the first conveying roller and the second conveying roller are arranged in parallel to each other, the yarns pass between the first conveying roller and the second conveying roller, an adjusting mechanism is arranged on the first conveying roller and the second conveying roller to adjust the clamping force and the tension of the yarns, a twisting mechanism is arranged on one side of the rotating disc away from the pay-off reel to rotate the rotating disc and twist the yarns, and the pay-off reel is arranged symmetrically and identically with the take-up reel.

[0007] By adopting the above technical scheme, the pay-off reel and the take-up reel are arranged symmetrically and identically, a plurality of groups of yarns are led out from between the first conveying roller and the second conveying roller on the pay-off reel, then pass through the first conveying roller and the second conveying roller on the rotating disc, and then the clamping force of the first conveying roller and the second conveying roller on the yarns is controlled by the adjusting mechanism, and the rotating speed of the first conveying roller and the second conveying roller on the pay-off reel and the take-up reel is adjusted, so that the rotating speed of the first conveying roller and the second conveying roller on the take-up reel is greater than that on the pay-off reel, thereby adjusting the tension of the yarns, and then the rotating disc is driven to rotate by the twisting mechanism to twist the yarns, thereby realizing the synchronous stretching and twisting detection of the plurality of groups of yarns. In the prior art, when the yarns are stretched, their diameters will become smaller due to the Poisson effect. For a twisted yarn, the thinning will inevitably lead to untwisting, and the test section of the yarns will become looser and looser, and the friction between the fibers will decrease. Therefore, when the performance of the yarns is not as expected, it is difficult to determine whether it is a problem of the material itself. In the application, the effective twist of the yarn test section is maintained at a constant value, and the yarns accept strength detection in their inherent and designed state, and the true mechanical properties are measured. Moreover, the yarns can be continuously detected, and compared with the prior art of detecting a section of yarn sample, the application continuously detects the entire roll of yarns, improves the detection integrity of the yarns, and the detection result is more convincing.

[0008] Optionally, the twisting mechanism comprises a first driving motor, a first driving gear, a driven gear and a connecting rod, the first driving motor is fixedly arranged on one side of the take-up reel away from the pay-off reel and located at the middle of the take-up reel, the first driving gear is rotatably arranged in the take-up reel, the output shaft of the driving motor is fixedly connected with the center of the first driving gear, a plurality of groups of the connecting rods are arranged corresponding to the rotating discs, the plurality of groups of the connecting rods are respectively fixedly arranged on one side of the plurality of groups of the rotating discs away from the pay-off reel, a plurality of groups of the driven gears are arranged corresponding to the connecting rods, the plurality of groups of the driven gears are respectively fixedly arranged on the outer peripheral wall of the plurality of groups of the connecting rods, and the plurality of groups of the driven gears are all in mesh with the first driving gear, and the yarns pass through the rotating discs and the connecting rods.

[0009] By adopting the above technical scheme, the first driving motor drives the first driving gear to rotate through the output shaft, the first driving gear is in mesh with the plurality of groups of the driven gears, thereby driving the plurality of groups of the rotating discs to rotate synchronously through the plurality of groups of the connecting rods, and the plurality of groups of the first conveying rollers and the plurality of groups of the second conveying rollers on the plurality of groups of the rotating discs respectively clamp the plurality of groups of the yarns, so that the plurality of groups of the rotating discs perform the circumferential motion with the take-up reel as the center, the plurality of groups of the yarns passing therethrough are synchronously and uniformly twisted, and the plurality of groups of the yarns are synchronously detected.

[0010] Optionally, the adjusting mechanism comprises a second driving motor, a second driving gear, a driven gear ring, a rotating ring, a clamping assembly, a first conveying assembly and a second conveying assembly, the second driving motor is fixedly arranged on one side of the take-up reel close to the pay-off reel, the second driving gear is rotatably arranged in the take-up reel, and the output shaft of the second driving motor is fixedly connected with the center of the second driving gear, the rotating ring is rotatably arranged on the outer peripheral wall of the rotating disc, the driven gear ring is fixedly sleeved on the outer peripheral wall of the rotating ring, the clamping assembly is arranged on the rotating disc for adjusting the clamping force of the yarn, the first conveying assembly and the second conveying assembly are the same and symmetrically arranged on the rotating disc, the first conveying assembly is used for driving the first conveying roller to rotate synchronously when the rotating ring rotates, and the second conveying assembly is used for driving the second conveying roller to rotate synchronously when the rotating ring rotates.

[0011] By adopting the above technical solution, the second drive motor drives the rotating ring to rotate through the second driving gear and the driven gear ring. Since the rotating ring and the rotating disk are rotatably connected, the rotation of the rotating ring is transmitted to the first conveying roller and the second conveying roller through the first conveying assembly and the second conveying assembly, respectively. By adjusting the rotation speed of the rotating ring, the rotation speed of the first conveying roller and the second conveying roller is adjusted, thereby adjusting the tension of the yarn. When it is necessary to increase the tension, the clamping assembly increases the clamping force on the yarn to avoid relative slippage between the yarn and the first conveying roller and the second conveying roller, thereby improving the accuracy of detection.

[0012] Optionally, the clamping assembly includes a first mounting base, a second mounting base, an elastic element, a guide rod, and an electromagnet. The first conveying roller is rotatably mounted on the first mounting base, and the second conveying roller is rotatably mounted on the second mounting base. A sliding groove is provided on the rotating disk. The ends of the first and second mounting bases near the rotating disk are slidably disposed within the sliding groove. Two sets of guide rods are provided, and the two sets of guide rods are symmetrically fixed on the mutually distant surfaces of the first and second mounting bases, with the mutually distant ends of the two sets of guide rods being inserted into and connected to the inner wall of the sliding groove. Two sets of elastic elements are provided, respectively disposed on the two sets of guide rods, for resetting the first and second mounting bases. Two sets of electromagnets are provided, and the two sets of electromagnets are respectively fixed on the mutually close surfaces of the first and second mounting bases.

[0013] By adopting the above technical solution, the energization and de-energization of the electromagnet can control the sliding of the first and second mounting seats within the sliding groove, thereby adjusting the gap between the first and second conveying rollers and achieving adjustment of the yarn clamping force. The guide rod and elastic element ensure smooth movement and automatic reset of the mounting seats, making the clamping force adjustable and stable. This allows for dynamic adjustment of the clamping force based on the yarn thickness and material, preventing yarn slippage or excessive compression and ensuring the reliability of tensile testing.

[0014] Optionally, the first conveying assembly includes a bevel gear ring, a rotating rod, a bevel gear, and a drive structure. The bevel gear ring is fixedly disposed at the end of the rotating ring near the wire feeding reel. An ear plate is fixedly disposed on the rotating reel. The rotating rod is rotatably disposed on the ear plate. The bevel gear is fixedly disposed at the end of the rotating rod away from the first conveying roller and meshes with the bevel gear ring. The drive structure is disposed on the first conveying roller and the bevel gear, and is used to drive the first conveying roller to rotate synchronously when the bevel gear rotates. The rotational speed of the bevel gear ring is greater than that of the rotating reel.

[0015] By adopting the above technical solution, the rotation of the rotating ring is transmitted to the rotating rod through the bevel gear ring and bevel gear, and then the first conveying roller is driven to rotate through the drive structure. The meshing of the bevel gear ring and bevel gear ensures the efficiency and synchronization of power transmission, matching the rotation speed of the first conveying roller with the rotation speed of the rotating ring. By controlling the rotation speed of the rotating ring, the yarn conveying speed is adjusted, thereby achieving continuous adjustment of yarn tension. The rotation speed of the bevel gear ring is greater than that of the rotating disk, avoiding yarn shrinkage or accumulation caused by twisting rotation.

[0016] Optionally, the drive structure includes a first universal joint coupling and a second universal joint coupling. One end of the first universal joint coupling is fixedly connected to the end of the rotating rod away from the bevel gear, and one end of the second universal joint coupling is fixedly connected to the end of the first conveying roller near the first universal joint coupling. The ends of the first universal joint coupling and the second universal joint coupling that are close to each other are mutually connected.

[0017] By adopting the above technical solution, the connection between the first universal joint coupling and the second universal joint coupling allows for efficient transmission of rotational motion when the angle changes. This ensures that even if the position of the first conveying roller shifts due to clamping adjustment, power can still be reliably transmitted from the rotating rod to the first conveying roller, avoiding transmission jamming or loss and improving the adaptability and stability of the equipment.

[0018] Optionally, multiple industrial cameras are provided on the side of the take-up reel near the pay-off reel, corresponding to the number of yarn strands. The industrial cameras are electrically connected to the first drive motor, the second drive motor, and the electromagnet, and are used to monitor the twist count of the yarn.

[0019] By employing the above technical solution, an industrial camera captures real-time images of the yarn, and image processing technology monitors the yarn's twist count and condition. The industrial camera is electrically connected to a first drive motor, a second drive motor, and an electromagnet, forming a closed-loop control system: when a change in twist count is detected, the system automatically adjusts the twisting speed, clamping force, or conveying speed to maintain a constant twist in the yarn test section. This intelligent monitoring improves the automation and accuracy of the testing, ensuring that the yarn undergoes strength testing in its designed state.

[0020] Optionally, the diameters of the first conveying roller and the second conveying roller are both greater than the widths of the first mounting base and the second mounting base, and both the first conveying roller and the second conveying roller are covered with rubber sleeves.

[0021] By adopting the above technical solution, the diameters of the first and second conveying rollers are larger than the width of the mounting base, improving the stability of clamping. The rubber sleeve covering the roller surface provides additional friction and cushioning, preventing the yarn from slipping or being damaged during stretching, while also reducing noise and vibration, ensuring the repeatability and reliability of test results.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustment mechanism controls the clamping force of the first and second conveying rollers on the yarn, and adjusts the rotation speed of the first and second conveying rollers on the pay-off and take-up reels, so that the rotation speed of the first and second conveying rollers on the take-up reel is greater than that of the first and second conveying rollers on the pay-off reel, thereby adjusting the yarn tension. Then, the twisting mechanism drives the rotating disk to rotate and twist the yarn, realizing the synchronous stretching and twisting detection of multiple yarns. In the prior art, when yarn is stretched, its diameter becomes thinner due to the Poisson effect. For a twisted yarn, thinning inevitably leads to untwisting, and the test section of the yarn becomes increasingly loose, reducing the friction between fibers. Therefore, when the performance of the yarn does not meet expectations, it is impossible to determine whether the problem lies with the yarn material itself. In this application, the effective twist of the yarn test section is maintained at a constant value. The yarn undergoes strength testing in its inherent, designed state, measuring its true intrinsic mechanical properties. Furthermore, this application allows for continuous testing of the yarn. Compared to the prior art which tests a section of yarn sample, this application continuously tests the entire roll of yarn, improving the completeness of the yarn testing and making the test results more convincing. 2. The energization and de-energization of the electromagnet control the sliding of the first and second mounting seats within the sliding groove, thereby adjusting the gap between the first and second conveying rollers and regulating the yarn clamping force. The guide rod and elastic element ensure smooth movement and automatic reset of the mounting seats, making the clamping force adjustable and stable. This allows for dynamic adjustment of the clamping force based on the yarn thickness and material, preventing yarn slippage or excessive compression and ensuring the reliability of tensile testing. 3. An industrial camera captures real-time images of the yarn, and image processing technology monitors the yarn's twist count and condition. The industrial camera is electrically connected to the first drive motor, the second drive motor, and an electromagnet, forming a closed-loop control system: when a change in twist count is detected, the system automatically adjusts the twisting speed, clamping force, or conveying speed to maintain a constant twist in the yarn test section. This intelligent monitoring improves the automation and accuracy of the inspection, ensuring that the yarn undergoes strength testing in its designed state. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This application discloses a textile yarn tensile properties testing device, referring to... Figure 1 , Figure 2 and Figure 3A textile yarn tensile property testing device includes a mounting platform 1. A first mounting base 251 and a second mounting base 252 are bolted to the mounting platform 1. A pay-off reel 11 is bolted to the first mounting base 251, and a take-up reel 12 is bolted to the second mounting base 252. Multiple sets of yarns are arranged to pass through the first mounting base 251 and the second mounting base 252. Multiple sets of rotating disks 13 are rotatably mounted on the take-up reel 12 according to the number of yarn strands. The multiple sets of rotating disks 13 are arranged in a circumferential array around the center of the take-up reel 12. A first conveying roller 14 and a second conveying roller 15 are rotatably mounted on the multiple sets of rotating disks 13. The first conveying roller 14 and the second conveying roller 15 are arranged parallel to each other. The yarn passes between the first conveying roller 14 and the second conveying roller 15. An adjustment mechanism 2 is provided on the first conveying roller 14 and the second conveying roller 15. A twisting mechanism 3 is provided on the side of the rotating disk 13 away from the pay-off reel 11. The pay-off reel 11 and the take-up reel 12 are symmetrical and identically arranged.

[0028] The pay-off reel 11 and take-up reel 12 are symmetrically and identically arranged. Multiple sets of yarns are drawn out from between the first conveyor roller 14 and the second conveyor roller 15 on the pay-off reel 11, and then pass through the first conveyor roller 14 and the second conveyor roller 15 on the rotating disk 13. The adjusting mechanism 2 controls the clamping force of the first conveyor roller 14 and the second conveyor roller 15 on the pay-off reel 11 and the take-up reel 12, and adjusts the rotation speed of the first conveyor roller 14 and the second conveyor roller 15 on the take-up reel so that the rotation speed of the first conveyor roller 14 and the second conveyor roller 15 on the take-up reel is greater than that of the first conveyor roller 14 and the second conveyor roller 15 on the pay-off reel. This achieves the adjustment of the yarn tension. Then, the twisting mechanism 3 drives the rotating disk 13 to rotate and twist the yarn, realizing the synchronous stretching and twisting detection of multiple yarns. In existing technologies, when yarn is stretched, its diameter decreases due to the Poisson effect. For a twisted yarn, this thinning inevitably leads to untwisting, causing the test section of the yarn to become increasingly loose and reducing inter-fiber friction. Therefore, when the yarn's performance does not meet expectations, it is impossible to determine whether the problem lies with the yarn material itself. In this embodiment, the effective twist of the yarn test section is maintained at a constant value. The yarn undergoes strength testing in its inherent, designed state, measuring its true intrinsic mechanical properties. Furthermore, this embodiment allows for continuous testing of the yarn. Compared to existing technologies that test only a section of yarn sample, this embodiment continuously tests the entire roll of yarn, improving the completeness of the yarn testing and making the test results more convincing.

[0029] Reference Figure 2 and Figure 4To achieve twisting of the yarn during take-up and unwound operations, the twisting mechanism 3 in this embodiment includes a first drive motor 31, a first drive gear 32, a driven gear 33, and a connecting rod 34. The first drive motor 31 is bolted to the take-up reel 12 on the side away from the unwound reel 11 and is located in the middle of the take-up reel 12. The first drive gear 32 is rotatably mounted inside the take-up reel 12, and the output shaft of the drive motor is bolted to the center of the first drive gear 32. Multiple sets of connecting rods 34 are provided corresponding to the rotating disk 13, and multiple sets of connecting rods 34 are respectively fixedly welded to the side of the multiple sets of rotating disks 13 away from the unwound reel 11. Multiple sets of driven gears 33 are provided corresponding to the connecting rods 34, and multiple sets of driven gears 33 are respectively welded and fixedly mounted on the outer peripheral wall of the multiple sets of connecting rods 34. All sets of driven gears 33 mesh with the first drive gear 32. The yarn passes through the rotating disk 13 and the connecting rod 34.

[0030] The first drive motor 31 drives the first drive gear 32 to rotate through the output shaft. The first drive gear 32 meshes with multiple sets of driven gears 33, thereby driving multiple sets of rotating disks 13 to rotate synchronously through multiple sets of connecting rods 34. With multiple sets of first conveying rollers 14 and multiple sets of second conveying rollers 15 on the multiple sets of rotating disks 13 clamping multiple sets of yarns respectively, this embodiment realizes that the multiple sets of rotating disks 13 perform circumferential motion around the take-up reel 12 as the center, and synchronously and evenly twists the multiple sets of yarns passing through them, thereby realizing synchronous detection of multiple sets of yarns.

[0031] Reference Figure 2 and Figure 3 When the first conveying roller 14 and the second conveying roller 15 need to perform different tension tests on the yarn, it is necessary to adjust the clamping force on the yarn and the winding and unwinding speed of the yarn. Therefore, the adjustment mechanism 2 in this embodiment includes a second drive motor 21, a second driving gear 22, a driven gear ring 23, a rotating ring 24, a clamping assembly 25, a first conveying assembly 26, and a second conveying assembly. The second drive motor 21 is bolted to the side of the take-up reel 12 near the unwinding reel 11, and the second driving gear 22 is rotatably mounted inside the take-up reel 12. The output shaft of motor 21 is fixedly connected to the center bolt of the second driving gear 22. The rotating ring 24 is rotatably mounted on the outer peripheral wall of the rotating disk 13. The driven gear ring 23 is welded to the outer peripheral wall of the rotating ring 24. The clamping assembly 25 is mounted on the rotating disk 13. The first conveying assembly 26 and the second conveying assembly are identical and symmetrically mounted on the rotating disk 13. The first conveying assembly 26 is used to drive the first conveying roller 14 to rotate synchronously when the rotating ring 24 rotates. The second conveying assembly is used to drive the second conveying roller 15 to rotate synchronously when the rotating ring 24 rotates.

[0032] The second drive motor 21 drives the rotating ring 24 to rotate via the second drive gear 22 and the driven gear ring 23. Since the rotating ring 24 and the rotating disk 13 are rotatably connected, the rotation of the rotating ring 24 is transmitted to the first conveying roller 14 and the second conveying roller 15 through the first conveying assembly 26 and the second conveying assembly, respectively. By adjusting the rotational speed of the rotating ring 24, the rotational speed of the first conveying roller 14 and the second conveying roller 15 is adjusted, thereby adjusting the tension of the yarn. When it is necessary to increase the tension, the clamping assembly 25 increases the clamping force on the yarn to prevent relative slippage between the yarn and the first conveying roller 14 and the second conveying roller 15, thereby improving the accuracy of detection.

[0033] Reference Figure 3 and Figure 5 In this embodiment, the clamping assembly 25 includes a first mounting base 251, a second mounting base 252, an elastic element 253, a guide rod 254, and an electromagnet 255. A first conveying roller 14 is rotatably mounted on the first mounting base 251, and a second conveying roller 15 is rotatably mounted on the second mounting base 252. A sliding groove is provided on the rotating disk 13. The ends of the first mounting base 251 and the second mounting base 252 near the rotating disk 13 are slidably mounted in the sliding groove. Two sets of guide rods 254 are provided, and the two sets of guide rods 254 are symmetrically fixedly welded and installed on the surfaces of the first mounting base 251 and the second mounting base 252 that are far apart from each other. The ends of the two sets of guide rods 254 that are far apart from each other are inserted and connected to the inner wall of the sliding groove. Two sets of elastic elements 253 are provided and installed on the two sets of guide rods 254 respectively, for resetting the first mounting base 251 and the second mounting base 252. Two sets of electromagnets 255 are installed, and the two sets of electromagnets 255 are fixedly installed on the surfaces of the first mounting base 251 and the second mounting base 252 that are close to each other.

[0034] The energization and de-energization of the electromagnet 255 control the sliding of the first mounting base 251 and the second mounting base 252 within the sliding groove, thereby adjusting the gap between the first conveying roller 14 and the second conveying roller 15 and adjusting the yarn clamping force. The guide rod 254 and the elastic element 253 ensure smooth movement and automatic reset of the mounting base, making the clamping force adjustable and stable. This allows for dynamic adjustment of the clamping force based on the yarn thickness and material, preventing yarn slippage or excessive compression and ensuring the reliability of the tensile test. In this embodiment, the elastic element 253 is a spring, which is sleeved on the guide rod 254. The spring is a preferred embodiment; in other embodiments, the elastic element 253 may be an elastic rubber block, etc.

[0035] Reference Figure 5In this embodiment, the first conveying assembly 26 includes a bevel ring 261, a rotating rod 262, a bevel gear 263, and a drive structure. The bevel ring 261 is fixedly welded to the end of the rotating ring 24 near the wire feeding reel 11. An ear plate is fixedly welded to the rotating reel 13. The rotating rod 262 is rotatably mounted on the ear plate. The bevel gear 263 is fixedly welded to the end of the rotating rod 262 away from the first conveying roller 14 and meshes with the bevel ring 261. The drive structure is mounted on the first conveying roller 14 and the bevel gear 263 and is used to drive the first conveying roller 14 to rotate synchronously when the bevel gear 263 rotates. The rotational speed of the bevel ring 261 is greater than that of the rotating reel 13.

[0036] The rotation of the rotating ring 24 is transmitted to the rotating rod 262 via the bevel ring 261 and bevel gear 263, and then drives the first conveying roller 14 to rotate via the drive structure. The meshing of the bevel ring 261 and bevel gear 263 ensures the efficiency and synchronization of power transmission, matching the rotation speed of the first conveying roller 14 with the rotation speed of the rotating ring 24. By controlling the rotation speed of the rotating ring 24, the yarn conveying speed is adjusted, thereby achieving continuous adjustment of yarn tension. The rotation speed of the ring is set higher than that of the rotating disk 13 to avoid yarn shrinkage or accumulation caused by twisting rotation.

[0037] Reference Figure 5 In order to realize the transmission of the first conveying roller 14 and the second conveying roller 15, the drive structure in this embodiment includes a first universal joint coupling 4 and a second universal joint coupling 5. One end of the first universal joint coupling 4 is welded and fixedly connected to the end of the rotating rod 262 away from the bevel gear 263. One end of the second universal joint coupling is welded and fixedly connected to the end of the first conveying roller 14 near the first universal joint coupling 4. The ends of the first universal joint coupling 4 and the second universal joint coupling 5 that are close to each other are connected by mutual insertion.

[0038] The connection between the first universal joint coupling 4 and the second universal joint coupling 5 allows for efficient transmission of rotational motion when the angle changes. This ensures that even if the position of the first conveying roller 14 shifts due to clamping adjustment, power can still be reliably transmitted from the rotating rod 262 to the first conveying roller 14, avoiding transmission jamming or loss and improving the adaptability and stability of the equipment. In this embodiment, the ends of the first universal joint coupling 4 and the second universal joint coupling 5 that are close to each other are connected by a spline socket connection.

[0039] Reference Figure 5To control the twist of the yarn, in this embodiment, multiple industrial cameras 6 are fixedly installed on the take-up reel 12 near the pay-off reel 11, corresponding to the number of yarn strands. The industrial cameras 6 are electrically connected to the first drive motor 31, the second drive motor 21, and the electromagnet 255. The industrial cameras 6 capture images of the yarn in real time, and monitor the twist count and state of the yarn through image processing technology. The industrial cameras 6, along with the first drive motor 31, the second drive motor 21, and the electromagnet 255, form a closed-loop control system: when a change in twist count is detected, the system automatically adjusts the twisting speed, clamping force, or conveying speed to maintain a constant twist in the yarn test section. This intelligent monitoring improves the automation and accuracy of the testing, ensuring that the yarn undergoes strength testing in its designed state.

[0040] In this embodiment, the diameters of the first conveying roller 14 and the second conveying roller 15 are both larger than the widths of the first mounting base 251 and the second mounting base 252, and both the first conveying roller 14 and the second conveying roller 15 are covered with rubber sleeves. The larger diameters of the first conveying roller 14 and the second conveying roller 15 compared to the width of the mounting bases improve clamping stability. The rubber sleeves covering the roller surfaces provide additional friction and cushioning, preventing the yarn from slipping or being damaged during stretching, while also reducing noise and vibration, ensuring the repeatability and reliability of the test results.

[0041] The implementation principle of the textile yarn tensile property testing device in this application embodiment is as follows: Tensile testing of yarn requires twisting to obtain more accurate intrinsic mechanical properties. A first drive motor 31 drives a first driving gear 32 and a driven gear 33, causing all rotating disks 13 to rotate synchronously, uniformly twisting the yarn. Simultaneously, a second drive motor 21 drives a second driving gear 22 and a driven gear ring 23, causing a rotating ring 24 to rotate. Power is then transmitted to the first conveying roller 14 and the second conveying roller 15 via a drive structure consisting of a bevel gear ring 261, bevel gear 263, and a universal joint coupling. A set tensile tension is generated by precisely controlling the speed difference between the conveying rollers on the take-up and pay-off reels 11. To ensure reliable transmission under high tension, the clamping assembly 25 is interlocked with the tension adjustment mechanism. An electromagnet 255 overcomes the resistance of the elastic element 253 to drive the first mounting base 251 and the second mounting base 252, thereby dynamically adjusting the clamping force between the rollers and preventing yarn slippage. Finally, the industrial camera 6 monitors the twist in real time and provides feedback, forming a closed-loop control with the first drive motor 31, the second drive motor 21, and the electromagnet 255 to ensure that the yarn is always subjected to tensile testing in its designed state, thus realizing a continuous, accurate, and complete performance evaluation of the entire roll of yarn.
