Description

Technical Field

[0001] The present invention relates to the technical field of textile yarn performance testing, in particular to a textile yarn tensile performance testing device and a method thereof. Background Art

[0002] Textile yarn is a continuous thread made from fibers through a spinning process and is the basic unit of various fabrics. To ensure that textile yarns meet uniform usage standards, they need to be tested for tensile properties. Tensile properties are a key indicator of a yarn's strength and ductility under external forces. Tensile testing machines are typically used to test yarn samples to measure the maximum tensile force the yarn can withstand before breaking, reflecting its toughness and elasticity.

[0003] Announcement number CN118937089B discloses a device for testing the tensile properties of textile yarns. The device uses an adjustment unit to adjust the yarn to different inclination angles for tensile testing, simulating the actual stress conditions of the yarn in actual use and increasing the diversity of testing. Furthermore, while the upper and lower clamping assemblies serve only as clamping points, the adjustment assembly and drive assembly can be used to test different tensile points on both sides of the yarn. This increases the number of tensile test points and further simulates the tensile forces experienced by the yarn at different locations in actual applications. This reduces the deviations or errors that may arise from single-point testing, improves the comprehensiveness of the test, and produces more realistic and effective test results, allowing for a more accurate assessment of the yarn's performance.

[0004] In the current textile industry, the existing textile yarn tensile performance testing equipment has a significant functional defect, that is, the equipment does not have the ability to clean the yarn surface. During the yarn production process, due to the continuous operation of multiple complex processes, many floating fibers and other types of impurities will remain on the yarn surface. For example, in the fiber combing process, some shorter fibers may not be completely and regularly incorporated into the main structure of the yarn, and thus remain free on the yarn surface; in the twisting process, due to factors such as mechanical friction, some fine fiber fragments fall off and adhere to the yarn. If these impurities remaining on the yarn surface are not cleaned, the tensile performance test equipment will be directly used for tensile performance testing. The presence of these impurities will increase the apparent diameter of the yarn. When the apparent diameter increases due to impurities, during the test process, the measured key parameters such as elongation at break or breaking strength will deviate, thereby affecting the accuracy and reliability of the test data, and misleading the subsequent product quality assessment and production process optimization based on these data. Summary of the Invention

[0005] The purpose of the present invention is to provide a textile yarn tensile performance testing device and method thereof, so as to solve the problem that the existing tensile testing equipment proposed in the above background technology does not have the ability to clean the yarn surface.

[0038] A driving motor 8 is fixed to the outside of one side of the tensile testing bench 1, and the output end of the driving motor 8 is coaxially fixed to one end of the reciprocating screw 7. A limiting groove 9 is embedded inside the side of the limiting slider 6 close to the two auxiliary rollers 14. Two limiting blocks 10 are symmetrically slidingly engaged inside the limiting groove 9. A bidirectional threaded rod 11 is rotatably installed inside the limiting groove 9. The interiors of the two limiting blocks 10 are penetrated by the bidirectional threaded rod 11, and the two limiting blocks 10 and the bidirectional threaded rod 11 are both threadedly connected. A stepping motor 12 is fixed to the outside of one side of the limiting slider 6, and the output shaft of the stepping motor 12 is coaxially fixed to one end of the bidirectional threaded rod 11.

[0039] A gear 13 is rotatably installed on the outside of one side of the two limiting sliders 6 close to the auxiliary roller 14 on the corresponding side. The outside of one side of the gear 13 is fixedly connected to the outside of one side of the auxiliary roller 14 on the corresponding side. Several flexible bristles 15 are installed at equal angles around the outer surfaces of the two auxiliary rollers 14.

[0040] The driving assembly includes a rack 16 and a limit plate 17. The rack 16 is longitudinally arranged on the outside of one side of the gear 13. The limit plate 17 is fixedly installed on the outside of the side of the rack 16 away from the gear 13. One side of the rack 16 is meshed with one side of the gear 13. A number of limit rods 18 are fixedly installed at equal intervals on the outside of one side of the rack 16 close to the limit plate 17. One end of the number of limit rods 18 is slidably installed on the outside of one side of the limit plate 17. A resistance spring 19 is sleeved and connected to the outside of one side of the number of limit rods 18. The two ends of the resistance spring 19 are respectively installed on the outside of one side of the rack 16 and the limit plate 17.

[0041] The collection component includes a suction pump 20 and a conduit 21. The suction pump 20 is fixedly installed on the outside of the side of the limiting slider 6 close to the reciprocating screw 7. The output end of the conduit 21 is connected to the suction end of the suction pump 20. The conduit 21 is provided with two input ends. Both input ends of the conduit 21 are connected and provided with a collection cover 22. The input end of the collection cover 22 is provided on the outside of one side of the auxiliary roller 14 on the corresponding side.

[0042] A comb plate 23 is fixed to the outside of the collecting cover 22 near the auxiliary roller 14, and a collecting box 25 is fixed to one side of the bottom end of the tensile testing bench 1. A spring stretching tube 24 is provided at the top end of the collecting box 25, and the input end of the spring stretching tube 24 is conductively connected to the discharge end of the suction pump 20.

[0043] In this embodiment, the two ends of the yarn that need to be stretched are first placed into the interior of the clamping jaw 1 2 and the clamping jaw 2 4, and then the two ends of the yarn are clamped and fixed by starting and closing the clamping jaw 1 2 and the clamping jaw 2 4. After clamping and fixing, the electric telescopic rod 3 is started to drive the clamping jaw 2 4 to retract a distance, so that the yarn is tightened and straightened, and then the electric telescopic rod 3 is controlled to stop stretching. When in use, the output shaft of the stepping motor 12 on one side can be controlled to rotate forward and reverse. When the stepping motor 12 is reversed, it will drive the bidirectional threaded rod 11 on one side to rotate synchronously. The bidirectional threaded rod 11 is connected to the through-thread of the limit block 10, so that the bidirectional threaded rod 11 rotates. It will drive the limit blocks 10 on both sides and the auxiliary roller 14 at the top to move synchronously in the limit groove 9 inside the limit slider 6, close to the center or to expand synchronously, thereby changing the spacing between the two auxiliary rollers 14, so that the cleaning component can adapt to yarns of different diameters, and the overall scope of application is wider. At the same time, through the limitation of the side limit plates 17, the guidance of the limit rods 18 and the compression, rebound and extrusion of the resistance springs 19, it can ensure that when the two auxiliary rollers 14 expand or move in the center, one side of the rack 16 can always be meshed with one side of the gear 13, ensuring that the subsequent gear 13 can rotate on one side of the rack 16, thereby ensuring the overall operation stability.

[0044] It should also be noted that when the spacing adjustment is completed, the drive motor 8 on one side is started, and the reciprocating screw 7 is driven to rotate by rotating the output shaft of the drive motor 8, and the limit slide 5 limits the limit slider 6, so that the reciprocating screw 7 rotates, so that the limit slider 6 drives the two auxiliary rollers 14 on one side to move outside the two sides of the yarn to be tested. The flexible bristles 15 on the outside of the auxiliary roller 14 are set, so that many floating fibers and other types of impurities remaining on the surface of the yarn can be automatically cleaned to ensure the apparent diameter of the yarn, thereby ensuring the accuracy of the measured key parameters such as elongation at break or breaking strength, and ensuring the accuracy and reliability of the test data.

[0045] It should also be noted that when the reciprocating screw 7 rotates, driving the limit slider 6 and the two auxiliary rollers 14 to move and clean the outside of the two sides of the yarn to be detected, the gear 13 at the bottom of the auxiliary roller 14 will engage and rotate on the outside of the rack 16 on one side, thereby driving the auxiliary roller 14 to rotate synchronously, thereby rotating and switching the flexible bristles 15 on the outside of the auxiliary roller 14 to ensure the overall cleaning effect, and at the same time, one side of the suction pump 20 can be started, and at the same time, the guide tube 21 and the collection cover 22 are turned on and aligned, so that the floating fibers and impurities swept down can be removed. The material is sucked and introduced into the interior of the collection box 25 through the spring stretch tube 24. At the same time, when the auxiliary roller 14 moves and rotates, the comb plate 23 on one side of the collection cover 22 is set, so that the floating hair fibers and impurities adhered to the inside of the flexible bristles 15 passing through the comb plate 23 can be cleaned synchronously, and then they are synchronously sucked and collected by the collection cover 22, so that the flexible bristles 15 can be automatically cleaned, ensuring the subsequent brushing and cleaning effect, ensuring the cleanliness of the cleaning components and the working environment, ensuring the subsequent detection effect, avoiding accumulation affecting the cleaning effect, and the overall use effect is better.

[0046] Example 2: Please refer to Figure 8 - Figure 11 This embodiment further explains Example 1. A moving seat 26 is provided on the inner side of the limiting slide groove 5 away from the limiting slider 6 for sliding engagement. A compacting component is provided on the outer side of the moving seat 26 close to the clamp 2. A pulling and disengaging component is provided on the outer side of the moving seat 26 close to the reciprocating screw rod 7.

[0047] The compacting assembly includes two auxiliary blocks 35 and two squeezing rollers 36 . The two auxiliary blocks 35 are slidably engaged and installed in the internal moving groove on one side of the moving seat 26 . One end of the two squeezing rollers 36 is rotatably installed on the outside of one side of the two auxiliary blocks 35 .

[0048] An auxiliary rod 34 is slidably installed inside the two auxiliary blocks 35, and both ends of the auxiliary rod 34 are fixedly installed inside one side of the moving seat 26. The auxiliary rod 34 is located on one side of the two auxiliary blocks 35 and is sleeved with an extrusion spring 37 on the outside. The two ends of the extrusion spring 37 are respectively installed on one side of the inner wall of the auxiliary block 35 and the moving seat 26.

[0049] The pulling and disengaging assembly includes a guide rod 27 and an insert block 30. The guide rod 27 is fixedly mounted inside the limiting slide groove 5, and the insert block 30 is fixedly mounted on the outside of the side of the limiting slider 6 close to the moving seat 26. The limiting slider 6 and the inside of one side of the moving seat 26 are penetrated by the guide rod 27. The guide rod 27, the limiting slider 6 and the moving seat 26 are all slidably connected. A return spring 28 is sleeved on the outside of one side of the guide rod 27. The two ends of the return spring 28 are respectively mounted on one side of the moving seat 26 and the inner wall of the limiting slide groove 5. A slot 29 is embedded in the inside of one side of the moving seat 26 close to the insert block 30. Spring blocks 32 are installed on the outside of both sides of the insert block 30. Slots 31 are embedded on the inner walls of both sides of the slot 29. Two interference blocks 33 are symmetrically fixed on the outside of the tensile test bench 1 close to the insert block 30. The distance between the two interference blocks 33 is greater than the distance between the two spring blocks 32, and the distance between the two interference blocks 33 is less than the width of the moving seat 26.

[0050] When the thread is pulled back, the thread is pulled out of the gear 22 and the thread is tightened, so that the thread is tightened and the thread is tightened. When the thread is pulled back, the thread is tightened and the thread is tightened, the thread is tightened and the thread is tightened. When the thread is pulled back, the thread is tightened and the thread is tightened, the thread is tightened and the thread is tightened.

[0051] It should also be noted that when the limit slider 6 moves back and resets, driving the movable seat 26 and the squeezing roller 36 to move to a certain position synchronously, the two sides of the movable seat 26 now conflict with the two sides of the interference block 33, and then as the limit slider 6 continues to move back and reset, the plug block 30 and the spring block 32 on one side of the limit slider 6 are disengaged from the slot 29 and the card slot 31 on one side of the movable seat 26. When completely disengaged, the rebound reset characteristics of the reset spring 28 originally stretched on one side are cooperated, thereby driving the movable seat 26 and the squeezing roller 36 on one side to move back and reset synchronously. When moving back, the yarn can be compacted again, making the overall use effect better. At the same time, the movable seat 26 and the squeezing roller 36 on one side can automatically move back and reset to ensure the stability of subsequent secondary use.

[0052] The present invention also provides a method for using a textile yarn tensile property testing device, comprising the following steps:

[0053] S1: First, the two ends of the yarn to be tensile tested are placed inside the clamping jaw 1 2 and the clamping jaw 2 4. Then, the clamping jaw 1 2 and the clamping jaw 2 4 are opened and closed to clamp the two ends of the yarn. After clamping, the electric telescopic rod 3 is activated to drive the clamping jaw 2 4 to retract one end, so that the yarn is tightened and straightened.

[0054] S2: When the yarn is stretched and straightened, the outer surface of the yarn is cleaned by the operation of the regulating component and the cleaning component, so as to remove impurities such as floating fibers remaining on the yarn surface;

[0055] S3: The process of cleaning the yarn surface by the operation of the regulating component and the cleaning component will trigger the collection component to run, thereby collecting the swept floating fibers and other impurities;

[0056] S4: When the adjustment component and the cleaning component are running to clean the yarn surface and then move back to reset, they will drive the compacting component on one side to run synchronously, so as to perform a secondary compaction operation on the cleaned yarn surface to ensure that the internal structure of the yarn is tight;

[0057] S5: When the adjustment component and the cleaning component have finished cleaning the yarn surface and reset, the pulling and disengaging component will be triggered to operate, causing the compacting component to automatically move back to ensure subsequent secondary use. After the overall cleaning and reset is completed, the electric telescopic rod 3 is moved again to drive the clamping jaw 2 4 and the yarn to perform a tensile test.
