Description

Technical Field

[0001] The present invention relates to the technical field of performance detection of textile yarns, and specifically to a device and method for detecting the tensile performance of textile yarns. Background Art

[0002] Textile yarn is a continuous linear material made from fibers through a spinning process, and it is the basic unit for forming various fabrics. To ensure that textile yarns meet unified usage standards, it is necessary to detect their tensile performance. Tensile performance is a key indicator for measuring the strength and ductility of yarns under external forces. Generally, a tensile testing machine is used to detect yarn samples to measure the maximum tensile force that the yarn can withstand before breaking, reflecting the toughness and elasticity of the yarn.

[0003] The publication number is CN118937089B, which discloses a device for detecting the tensile performance of textile yarns. Through an adjustment unit, the yarn can be adjusted to different inclination angles for tensile testing, simulating the real stress situation of the yarn in actual use and increasing the diversity of detection. At the same time, when the clamping components on the upper and lower sides are only used as clamping points, the cooperation of the adjustment component and the driving component can be used to detect different tensile positions on both sides of the yarn, increasing the tensile detection positions, further simulating the situation where the yarn bears tensile forces at different positions in actual applications, reducing the deviation or error that may be caused by single-point detection, improving the comprehensiveness of detection, obtaining more real and effective detection results, and thus more accurately evaluating the performance of the yarn.

[0004] In the current textile industry, there is a significant functional defect in existing devices for detecting the tensile performance of textile yarns, that is, the device does not have the ability to clean the surface of the yarn. During the production process of the yarn, due to the continuous operation of multiple complex processes, there will be many floating hair fibers and other types of impurities remaining on the surface of the yarn. For example, in the fiber carding process, some shorter fibers may not be completely and regularly incorporated into the main structure of the yarn and thus float on the surface of the yarn; in the twisting process, due to factors such as mechanical friction, some fine fiber debris falls off and adheres to the yarn. If these impurities remaining on the surface of the yarn are not cleaned and the detection device is directly used for tensile performance detection, the presence of these impurities will increase the apparent diameter of the yarn. When the apparent diameter increases due to impurities, during the detection process, key parameters such as the elongation at break or breaking strength measured will deviate, thereby affecting the accuracy and reliability of the detection data and misleading the subsequent product quality evaluation 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 property detection device and its method, so as to solve the problem proposed in the above background technology that the existing tensile detection device does not have the ability to clean the surface of the yarn.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0021] On the outside of one side of the tensile test bench 1, a driving motor 8 is fixedly connected. The output end of the driving motor 8 is coaxially fixed to one end of the reciprocating lead screw 7. Inside one side of the limit slider 6 close to the two auxiliary rollers 14, a limit groove 9 is embedded. Inside the limit groove 9, two limit blocks 10 are symmetrically slidably engaged. Inside the limit groove 9, a bidirectional threaded rod 11 is rotatably installed. The two limit blocks 10 are both penetrated by the bidirectional threaded rod 11. Between the two limit blocks 10 and the bidirectional threaded rod 11, there is a threaded connection through. On the outside of one side of the limit slider 6, a stepping motor 12 is fixedly connected. The output shaft of the stepping motor 12 is coaxially fixed to one end of the bidirectional threaded rod 11.

[0022] On the outside of one side of the two limit sliders 6 close to the auxiliary rollers 14 on the corresponding side, gears 13 are rotatably installed. On the outside of one side of the gear 13, it is fixedly connected to the outside of one side of the auxiliary roller 14 on the corresponding side. On the outer surface of the two auxiliary rollers 14, a number of flexible bristles 15 are equiangularly installed in a circular manner.

[0023] 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. On the outside of one side of the rack 16 close to the limit plate 17, a number of limit rods 18 are fixedly installed at equal intervals. One ends of the number of limit rods 18 are all slidably installed through the outside of one side of the limit plate 17. On the outside of one side of the number of limit rods 18, a number of abutting springs 19 are sleeved and connected. The two ends of the abutting spring 19 are respectively installed on the outside of one side of the rack 16 and the limit plate 17.

[0024] The collection assembly includes a suction pump 20 and a conduit 21. The suction pump 20 is fixedly installed on the outside of one side of the limit slider 6 close to the reciprocating lead screw 7. The output end of the conduit 21 is connected and communicated with the suction end of the suction pump 20. The conduit 21 is provided with two input ends. The two input ends of the conduit 21 are both connected and communicated with a collection cover 22. The input end of the collection cover 22 is arranged on the outside of one side of the auxiliary roller 14 on the corresponding side.

[0025] On the outside of one side of the collection cover 22 close to the auxiliary roller 14, a comb tooth plate 23 is fixedly connected. On one side of the bottom end of the tensile test bench 1, a collection box 25 is fixedly connected. On the top end of the collection box 25, a spring stretching tube 24 is connected and communicated. The input end of the spring stretching tube 24 is connected and communicated with the discharge end of the suction pump 20.

[0026] In this embodiment, first, both ends of the yarn to be subjected to tensile testing are placed inside the first gripper 2 and the second gripper 4. Then, the first gripper 2 and the second gripper 4 are activated to close, thereby clamping and fixing both ends of the yarn. After clamping and fixing, the electric telescopic rod 3 is activated to drive the second gripper 4 to retract a certain distance, so that the yarn is stretched and straightened. Then, the electric telescopic rod 3 is controlled to stop stretching. During use, the output shaft of the stepping motor 12 on one side can be controlled to rotate forward and backward. When the stepping motor 12 rotates forward and backward, it will drive the bidirectional threaded rod 11 on one side to rotate synchronously. Through the through-threaded connection between the bidirectional threaded rod 11 and the limit block 10, when the bidirectional threaded rod 11 rotates, it will drive the two limit blocks 10 on both sides and the auxiliary rollers 14 at the top to move synchronously and centrally closer or expand in the limit groove 9 inside the limit slider 6, thereby changing the distance between the two auxiliary rollers 14. In this way, the cleaning component can adapt to yarns of different diameters, and the overall application range is wider. At the same time, through the limitation of the side limiting plate 17, the guidance of the limiting rod 18, and the compression and rebound extrusion of the abutting spring 19, it can be ensured that when the two auxiliary rollers 14 move in an expanding or centralizing manner, one side of the rack 16 can always be meshed and connected with one side of the gear 13, ensuring that the subsequent gear 13 can rotate on one side of the rack 16 and guaranteeing the overall operation stability.

[0027] It should also be noted that when the spacing adjustment is completed, at this time, the drive motor 8 on one side is activated. The rotation of the output shaft of the drive motor 8 drives the reciprocating lead screw 7 to rotate. With the limitation of the limit slider 6 by the limit chute 5, the reciprocating lead screw 7 rotates, causing the limit slider 6 to drive the two auxiliary rollers 14 on one side to move outside both sides of the yarn to be detected. Through the arrangement of the flexible bristles 15 on the outside of the auxiliary rollers 14, the residual floating hairs, fibers, and other types of impurities on the surface of the yarn can be automatically cleaned, ensuring the apparent diameter of the yarn, thereby ensuring the accuracy of key parameters such as the measured elongation at break or breaking strength, and guaranteeing the accuracy and reliability of the detection data.

[0028] It should also be noted that when the reciprocating lead screw 7 rotates to drive the limit slider 6 and the two auxiliary rollers 14 to move and clean on the outer sides of the yarn to be detected, at this time, the gear 13 at the bottom of the auxiliary roller 14 will engage and rotate on the outside of one side rack 16, thereby driving the auxiliary roller 14 to rotate synchronously, so as to rotate and switch the flexible bristles 15 on the outside of the auxiliary roller 14, ensuring the overall cleaning effect. At the same time, the suction pump 20 on one side can be started, and at the same time, in cooperation with the conduction and alignment of the conduit 21 and the collection hood 22, the floating hair fibers and impurities swept down can be 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, through the setting of the comb tooth plate 23 on one side of the collection hood 22, the floating hair fibers and impurities adhered to the inside of the flexible bristles 15 passing through the comb tooth plate 23 can be cleaned synchronously, and then sucked and collected by the collection hood 22. In this way, the flexible bristles 15 can be automatically cleaned, ensuring the subsequent brushing and cleaning effect, ensuring the cleanliness of the cleaning assembly and the working environment, ensuring the subsequent detection effect, and avoiding accumulation from affecting the cleaning effect. The overall use effect is better.

[0029] Embodiment 2: Please refer to Figure 8 - Figure 11 , this embodiment further describes Embodiment 1. A moving seat 26 is slidably and snap-fitted inside the side of the limit chute 5 away from the limit slider 6. A compaction assembly is arranged on the outer side of the moving seat 26 close to the jaw 1 2, and a pulling and disengaging assembly is arranged on the outer side of the moving seat 26 close to the reciprocating lead screw 7.

[0030] The compaction assembly includes two auxiliary blocks 35 and two extrusion rollers 36. The two auxiliary blocks 35 are slidably and snap-fitted and installed in the moving grooves inside one side of the moving seat 26, and one end of each of the two extrusion rollers 36 is rotatably installed on the outer side of one of the two auxiliary blocks 35.

[0031] An auxiliary rod 34 is slidably installed through the interiors of the two auxiliary blocks 35. Both ends of the auxiliary rod 34 are fixedly installed inside one side of the moving seat 26. On the outer side of one side of the two auxiliary blocks 35, compression springs 37 are sleeved on the auxiliary rod 34. Both ends of the compression springs 37 are respectively installed on one side of the auxiliary block 35 and the inner wall of the moving seat 26.

[0032] The pulling and detaching component includes a guiding rod 27 and an inserting block 30. The guiding rod 27 is fixedly installed inside the limit sliding groove 5. The inserting block 30 is fixedly installed on the outer side of one side of the limit sliding block 6 close to the moving seat 26. The guiding rod 27 penetrates through both the limit sliding block 6 and the inner part of one side of the moving seat 26. The guiding rod 27 is in a through-sliding connection with both the limit sliding block 6 and the moving seat 26. A return spring 28 is sleeved on the outer side of one side of the guiding rod 27. The two ends of the return spring 28 are respectively installed on one side of the moving seat 26 and the inner wall of the limit sliding groove 5. A slot 29 is embeddedly arranged inside one side of the moving seat 26 close to the inserting block 30. Spring catch blocks 32 are installed on the outer sides of both sides of the inserting block 30. Card slots 31 are embeddedly arranged on the inner walls of both sides of the slot 29. Two abutting blocks 33 are symmetrically and fixedly installed on the outer side of one side of the tensile test bench 1 close to the inserting block 30. The distance between the two abutting blocks 33 is greater than the distance between the two spring catch blocks 32, and the distance between the two abutting blocks 33 is less than the width of the moving seat 26.

[0033] In this embodiment, when the limit sliding block 6 drives the auxiliary roller 14 to move to the other end of the yarn to be detected, at this time, the inserting block 30 and the spring catch block 32 on one side of the limit sliding block 6 are inserted and engaged into the slot 29 and the card slot 31 inside one side of the moving seat 26. When the limit sliding block 6 drives the auxiliary roller 14 to move back and reset, it will drive the moving seat 26 and the extrusion rollers 36 symmetrically arranged at its top to move synchronously. When moving, the return spring 28 connected between one side inner wall of the moving seat 26 and the limit sliding groove 5 will be stretched synchronously. At the same time, through the extrusion of the auxiliary rod 34, the auxiliary block 35 and the extrusion spring 37, the two extrusion rollers 36 can extrude and compact the yarn when moving synchronously, so as to ensure the tight internal structure of the yarn, enhance the cohesion between fibers, effectively improve the breaking strength of the yarn, and can accurately show the maximum tensile force that the yarn can actually withstand during the tensile test, making the overall test result more accurate and the use effect better.

[0034] It should also be noted that when the limit sliding block 6 moves back and resets to drive the moving seat 26 and the extrusion rollers 36 to move synchronously to a certain position, at this time, both sides of the moving seat 26 abut against both sides of the abutting blocks 33. After that, as the limit sliding block 6 continues to move back and reset, the inserting block 30 and the spring catch block 32 on one side of the limit sliding block 6 are disengaged from the slot 29 and the card slot 31 inside one side of the moving seat 26. When completely disengaged, at this time, with the rebound and reset characteristics of the return spring 28 stretched on one side originally, it drives the moving seat 26 and one side extrusion roller 36 to move back and reset synchronously. When moving back, it can compact the yarn again, making the overall use effect better. At the same time, the moving seat 26 and one side extrusion roller 36 can automatically move back and reset, ensuring the stability of subsequent secondary use.

[0035] The present invention also provides a use method of a textile yarn tensile property detection device, including the following steps: S1: First, place both ends of the yarn to be stretch - tested into the interiors of gripper one 2 and gripper two 4. Then, start and close gripper one 2 and gripper two 4 to clamp and fix both ends of the yarn. After clamping and fixing, start the electric telescopic rod 3 to drive gripper two 4 to retract a certain distance, so that the yarn is stretched and tightened. S2: When the yarn is stretched and tightened, at this time, through the operation of the adjustment component and the cleaning component, the outer surface of the yarn is cleaned by fitting and moving, so as to clean impurities such as residual floating hair fibers on the surface of the yarn. S3: During the process of cleaning the surface of the yarn by the operation of the adjustment component and the cleaning component, it will trigger the operation of the collection component to collect impurities such as swept - off floating hair fibers. S4: When the adjustment component and the cleaning component complete the cleaning of the yarn surface and move back to reset, it will drive the compaction component on one side to operate synchronously to perform a secondary compaction operation on the cleaned yarn surface to ensure the tight internal structure of the yarn. S5: When the adjustment component and the cleaning component complete the cleaning of the yarn surface and reset, at this time, it will trigger the operation of the pulling - off component, so that the compaction component automatically moves back to ensure subsequent secondary use. After the overall cleaning and reset is completed, move the electric telescopic rod 3 again to drive gripper two 4 and the yarn to perform the stretch - test.
