Description

Technical Field

[0001] This invention relates to the field of textile product testing technology, and in particular to a performance testing device and method for textile yarn products. Background Technology

[0002] Yarn is a type of textile product made from various textile fibers processed into a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. Yarn is divided into short fiber yarn and continuous filament yarn. The quality of textile yarn directly determines the quality of the finished products made from it. Therefore, it is usually necessary to conduct comprehensive performance testing on textile yarn during the textile process. Among the testing parameters, the tensile strength of textile yarn is an important one.

[0003] Currently, most textile yarn products undergo tensile strength testing by fixing the yarn between a clamping assembly and a tensile tester. A cylinder then pulls the tester to measure the yarn's tensile strength. To ensure accuracy, multiple tensile tests are required, and the data from these tests is used to accurately determine the yarn's tensile strength. However, if the yarn breaks during tensile testing, the broken ends must be removed from both the clamping assembly and the clamping assembly. This means that before conducting the next round of tensile strength testing, the broken yarn from the previous test must be processed before the yarn can be re-fixed between the clamping assembly and the tensile tester for further testing, resulting in low efficiency.

[0004] To address these issues, we propose a performance testing device and method for textile yarn products. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of low efficiency in the current technology of textile yarn products, which requires repeated tensile strength testing of yarn. Therefore, this invention proposes a performance testing device and method for textile yarn products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A performance testing device for textile yarn products includes a concave operating table. A servo motor is fixedly connected to the inner top wall of the operating table. A turntable that fits against the top of the operating table is fixedly connected to the output end of the servo motor. Two symmetrical L-shaped fixing frames are fixedly connected to the top of the turntable. A threaded rod is connected to the inner top wall of each L-shaped fixing frame and the top of the turntable via a bearing. A square locking rod is fixedly connected to one end of each threaded rod at the top of the L-shaped fixing frame. Each of the two sets of L-shaped fixing frames has a corresponding square locking rod at its top, and a corresponding transmission mechanism is engaged on the surface of one of the square locking rods. The transmission mechanism includes a concave connecting frame, and the top of the concave connecting frame is fixedly mounted with... Equipped with a cylinder, a second servo motor is fixedly installed on the inner bottom wall of the concave connecting frame. A first circular gear is fixedly connected to the output end of the second servo motor. A matching second circular gear is connected to the surface of the first circular gear. A rotating rod is fixedly connected to the bottom of the second circular gear. The surface of the rotating rod is connected between the inner bottom wall and the bottom of the concave connecting frame through a bearing. The bottom end of the rotating rod extends to the bottom of the concave connecting frame and is provided with a square slot corresponding to the square locking rod for limiting. A T-shaped mounting plate is threadedly connected to the surface of the threaded rod. A tension gauge is fixedly connected to the surface of the T-shaped mounting plate. A clamping assembly connected to the top of the turntable is provided below the tension gauge.

[0008] Preferably, the clamping assembly includes a concave positioning frame, the bottom of which is fixedly connected to the top of the turntable. An adjusting screw is threaded between one side of the concave positioning frame and the corresponding inner sidewall. One end of the adjusting screw located on the inner sidewall of the concave positioning frame is connected to a No. 1 clamping plate via a bearing. The other side of the No. 1 clamping plate and the inner sidewall corresponding to the concave positioning frame are provided with matching limiting teeth.

[0009] Preferably, a telescopic rod is fixedly connected to one side of the first clamping plate, and the other end of the first telescopic rod is fixedly connected to the inner side wall corresponding to the concave positioning frame.

[0010] Preferably, the end of the adjusting screw located outside the surface of the concave positioning frame is fixedly connected to a rotating handle, and the surface of the rotating handle is provided with two symmetrical extension rods.

[0011] Preferably, the clamping assembly further includes an L-shaped positioning frame, one side of which is fixedly connected to the side corresponding to the concave positioning frame, a second telescopic rod is fixedly connected to the inner wall of the L-shaped positioning frame, a spring is sleeved on the surface of the second telescopic rod, a second clamping plate is fixedly connected to the other end of the second telescopic rod, and a limiting hole is provided on the inner wall of the concave positioning frame that is connected to and corresponds to the second clamping plate.

[0012] Preferably, an L-shaped support frame is fixedly connected to the top of the cylinder, and the bottom of the L-shaped support frame is fixedly connected to the top of the operating table.

[0013] Preferably, the top of the operating table is provided with a communicating semi-circular positioning groove, and the inner wall of the semi-circular positioning groove is fitted with a matching positioning rod, the top end of the positioning rod being fixedly connected to the bottom of the turntable.

[0014] Preferably, the inner wall of the L-shaped fixing frame is provided with a communicating limiting slide groove, the inner wall of the limiting slide groove is slidably connected to a limiting slide plate, and one side of the limiting slide plate is fixedly connected to the corresponding side of the T-shaped mounting plate.

[0015] The present invention also provides a testing method for a performance testing device for textile yarn products, comprising the following steps:

[0016] Step A: First, fix one end of the tested textile yarn to the pull ring designed at the bottom of the tensile tester, and fix the other end to the clamping assembly. Then, drive the concave connecting frame in the transmission mechanism to make a vertical downward linear movement through the cylinder, so that the square slot designed at the bottom of the rotating rod fits and engages with the square clamp connected to the top of the corresponding threaded rod below. When the second servo motor drives the first circular gear, the second circular gear and the rotating rod to rotate relative to each other, at this time, the threaded rod can drive the T-shaped mounting plate with the surface thread design to cooperate with the textile yarn fixed between the tensile tester and the clamping assembly to perform strength stretching under the transmission mechanism.

[0017] Step B: To ensure that either of the two sets of tensioning devices designed on the top of the turntable can switch back and forth with the transmission mechanism through the corresponding L-shaped fixing bracket, threaded rod, square clamping rod, T-shaped mounting plate, tension gauge, and clamping assembly, and to continuously test the strength of the next round of textile yarn, a servo motor is designed on the top wall of the operating table to rotate in conjunction with the turntable. By rotating the servo motor in both forward and reverse directions by a certain angle, either of the two sets of tensioning devices designed on the top of the turntable can be engaged with the separately designed transmission mechanism.

[0018] Compared with the prior art, the present invention provides a performance testing device for textile yarn products, which has the following beneficial effects:

[0019] 1. This device for testing the performance of textile yarn products uses a servo motor to rotate at specific angles in both forward and reverse directions. This is to coordinate with one of the two sets of symmetrical stretching devices on the top of the turntable, consisting of an L-shaped fixing frame, a threaded rod, a square clamping rod, a T-shaped mounting plate, a tension gauge, and a clamping assembly. As the servo motor drives the turntable to rotate in both directions, the device precisely aligns with the lower part of the transmission mechanism. The cylinder drives the transmission mechanism to engage with the corresponding stretching device, efficiently cooperating with the yarn to perform repeated tensile strength tests.

[0020] 2. This device for testing the performance of textile yarn products adds a new clamping assembly consisting of an L-shaped positioning frame, a second telescopic rod, a spring, and a second clamping plate to the traditional clamping assembly consisting of a concave positioning frame, an adjusting screw, a first clamping plate, a limiting tooth, and a first telescopic rod. This new clamping assembly helps to securely clamp the corresponding other end of the yarn winding tensile tester, preventing the textile yarn from detaching from the clamping assembly and affecting the efficiency of the yarn tensile test.

[0021] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention uses a servo motor that rotates 180 degrees in each forward and reverse rotation. This allows either of the two sets of tensioning devices designed on the top of the turntable, consisting of an L-shaped fixing frame, a threaded rod, a square clamping rod, a T-shaped mounting plate, a tension gauge, and a clamping assembly, to be engaged by the transmission mechanism. This effectively reduces the waiting time for the next round of yarn inspection and efficiently coordinates the yarn for repeated tensile strength testing. This ensures that the yarn's tensile strength can be more accurately judged under multiple tensile strength tests. Attached Figure Description

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example 1:

[0033] Reference Figure 1-Figure 5A performance testing device for textile yarn products includes a concave operating table 1. A servo motor 2 is fixedly connected to the inner top wall of the operating table 1. A turntable 3, which is attached to the top of the operating table 1, is fixedly connected to the output end of the servo motor 2. Two symmetrical L-shaped fixing frames 4 are fixedly connected to the top of the turntable 3. Threaded rods 5 are connected to the inner top wall of each L-shaped fixing frame 4 and the top of the turntable 3 via bearings. A square locking rod 6 is fixedly connected to one end of the threaded rod 5 at the top of the L-shaped fixing frame 4. Corresponding square locking rods 6 are provided at the top of both sets of L-shaped fixing frames 4, and a corresponding transmission mechanism 7 is engaged on the surface of one of the square locking rods 6. The transmission mechanism 7 includes a concave connecting frame 701. A cylinder 8 is fixedly installed on the top of the concave connecting frame 701. A second servo motor 702 is fixedly installed on the inner bottom wall of 01. The output end of the second servo motor 702 is fixedly connected to a first circular gear 703. A matching second circular gear 704 is connected to the surface of the first circular gear 703. A rotating rod 705 is fixedly connected to the bottom of the second circular gear 704. The surface of the rotating rod 705 is connected to the inner bottom wall and bottom of the concave connecting frame 701 through a bearing. The bottom end of the rotating rod 705 extends to the bottom of the concave connecting frame 701 and is provided with a square slot 706 corresponding to the square locking rod 6 for limiting. A T-shaped mounting plate 9 is threadedly connected to the surface of the threaded rod 5. A tension gauge 10 is fixedly connected to the surface of the T-shaped mounting plate 9. A clamping assembly 11 connected to the top of the turntable 3 is provided below the tension gauge 10.

[0034] In this invention, when testing the tensile strength of textile yarn, the textile yarn is simply fixed between the clamping assembly 11 and the tensile gauge 10. Then, the cylinder 8 drives the concave connecting frame 701 to move vertically downwards, allowing the square slot 706 at the bottom of the rotating rod 705 below the bottom of the concave connecting frame 701 to engage with the square locking rod 6 corresponding to the top of the threaded rod 5 below. The threaded rod 5, engaged at the bottom of the rotating rod 705, is then driven by the mutual transmission between the second servo motor 702, the first circular gear 703, the second circular gear 704 in the transmission mechanism 7, and the rotating rod 705. This drives the T-shaped mounting plate 9 on the surface of the threaded rod 5 to move vertically upwards along the surface of the threaded rod 5, thereby cooperating with the tensile gauge 10 at the bottom of the T-shaped mounting plate 9 to test the tensile strength of the textile yarn. To ensure the accuracy of the tensile strength test, the test is generally repeated multiple times. Tensile testing, through the experimental data obtained from several trials, accurately determines the quality of the tensile strength of textile yarn. Therefore, to improve the efficiency of repeated tensile testing of textile yarn, two sets of symmetrical L-shaped fixing frames 4 are designed on the top of the turntable 3. The turntable 3 is rotated in both directions according to a preset threshold by a servo motor 2, with each rotation angle being 180 degrees. This ensures that one of the square locking rods 6 at the top of the threaded rod 5 of the two L-shaped fixing frames 4 on the top of the turntable 3 is accurately positioned directly below the rotating rod 705 with each rotation of the servo motor 2, engaging with the corresponding transmission mechanism 7. This ensures that the corresponding textile yarns in the two sets of L-shaped fixing frames 4 are tested in one group, while the broken textile yarn in the other group is removed after testing and replaced with the textile yarn to be tested. This allows for continuous back-and-forth testing and replacement, further improving the efficiency of repeated tensile testing of textile yarn.

[0035] Example 2:

[0036] Reference Figure 1 and Figure 6A performance testing device for textile yarn products includes a clamping assembly 11 connected to the top of a turntable 3. The clamping assembly 11 includes a concave positioning frame 1101. The bottom of the concave positioning frame 1101 is fixedly connected to the top of the turntable 3. An adjusting screw 1102 is threaded between one side of the concave positioning frame 1101 and the corresponding inner sidewall. One end of the adjusting screw 1102 located on the inner sidewall of the concave positioning frame 1101 is connected to a first clamping plate 1103 via a bearing. The other side of the first clamping plate 1103 and the corresponding inner sidewall of the concave positioning frame 1101 are provided with matching limiting teeth 1104. One side of the first clamping plate 1103 is fixedly connected to a first telescopic rod 1105. The other end of the first telescopic rod 1105 is fixedly connected to the corresponding inner sidewall of the concave positioning frame 1101. The end of the adjusting screw 1102 located outside the surface of the concave positioning frame 1101 is fixedly connected to a rotating handle, and the surface of the rotating handle is provided with two symmetrical extension rods.

[0037] In this invention, when fixing the textile yarn between the first clamping plate 1103 and the inner wall of the concave positioning frame 1101 in the clamping assembly 11, it is only necessary to place one end of the textile yarn on the inner wall of the concave positioning frame 1101, and then rotate the adjusting screw 1102 in the pre-set threaded groove inside the concave positioning frame 1101 by rotating the extension rod on the surface of the handle, thereby pushing the first clamping plate 1103 towards the textile yarn placed on the inner wall of the concave positioning frame 1101. The clamping mechanism includes a telescopic rod 1105 designed between the clamping plate 1103 and the concave positioning frame 1101. This telescopic rod ensures that the clamping plate 1103 can slide smoothly along the inner bottom wall of the concave positioning frame 1101. Furthermore, the corresponding surfaces of the clamping plate 1103 and the inner side wall of the concave positioning frame 1101 are designed with limiting teeth 1104, which further enhances the limiting effect between the textile thread and the clamping plate 1103 and the inner side wall of the concave positioning frame 1101.

[0038] Example 3:

[0039] Reference Figure 1 , Figure 6 and Figure 7 A performance testing device for textile yarn products includes a clamping assembly 11 connected to the top of a turntable 3. The clamping assembly 11 also includes an L-shaped positioning frame 1106. One side of the L-shaped positioning frame 1106 is fixedly connected to the side corresponding to the concave positioning frame 1101. A second telescopic rod 1107 is fixedly connected to the inner wall of the L-shaped positioning frame 1106. A spring 1108 is sleeved on the surface of the second telescopic rod 1107. A second clamping plate 1109 is fixedly connected to the other end of the second telescopic rod 1107. The inner wall of the concave positioning frame 1101 is provided with a limiting hole 1110 that communicates with and corresponds to the second clamping plate 1109.

[0040] In this invention, to further improve the fixation of the clamping assembly 11 on the textile yarn, an auxiliary assembly consisting of an L-shaped positioning frame 1106, a second telescopic rod 1107, a spring 1108, and a second clamping plate 1109, along with a corresponding limiting hole 1110, is designed on one side of the traditional concave positioning frame 1101. In use, one end of the textile yarn placed between the first clamping plate 1103 and the concave positioning frame 1101 passes through the limiting hole 1110 to the corresponding position of the concave positioning frame 1101 and the second clamping plate 1109. With the buffer between the second telescopic rod 1107 and the spring 1108, the second clamping plate 1109 can clamp the end of the textile yarn protruding from the limiting hole 1110 again, thereby improving the fixation of the textile yarn and preventing the textile yarn from detaching from the clamping assembly 11, which would affect the efficiency of the tensile test.

[0041] Example 4:

[0042] Reference Figure 1 , Figure 4 and Figure 5 A performance testing device for textile yarn products includes a concave operating table 1. A servo motor 2 is fixedly connected to the inner top wall of the operating table 1. A turntable 3 that fits against the top of the operating table 1 is fixedly connected to the output end of the servo motor 2. Two symmetrical L-shaped fixing frames 4 are fixedly connected to the top of the turntable 3. Threaded rods 5 are connected to the inner top wall of the L-shaped fixing frames 4 and the top of the turntable 3 through bearings. A square clamping rod 6 is fixedly connected to one end of the threaded rod 5 at the top of the L-shaped fixing frame 4. A corresponding transmission mechanism 7 is engaged on the surface of the square clamping rod 6. The transmission mechanism 7 includes a concave connecting frame 701. A cylinder 8 is fixedly installed on the top of the concave connecting frame 701. An L-shaped support frame 12 is fixedly connected to the top of the cylinder 8. The bottom of the L-shaped support frame 12 is fixedly connected to the top of the operating table 1.

[0043] In this invention, to ensure that the rotating rod 705 in the transmission mechanism 7 can automatically engage with the square locking rod 6 corresponding to the top of the threaded rod 5 below, a cylinder 8 is installed between the concave connecting frame 701 and the inner top wall of the L-shaped support frame 12. This allows the concave connecting frame 701 in the transmission mechanism 7 to automatically engage with the corresponding threaded rod 5 below under the movement of the cylinder 8. At the same time, the transmission mechanism 7 and the threaded rod 5 are designed separately, which helps to engage with the threaded rod 5 in another set of L-shaped fixing frames 4. This allows the threaded rods 5 in the two sets of L-shaped fixing frames 4 designed on the top of the turntable 3 to undergo multiple tensile tests with the textile yarn fixed between the tension gauge 10 and the clamping assembly 11 under the transmission mechanism 7.

[0044] Example 5:

[0045] Reference Figures 1-3A performance testing device for textile yarn products includes a concave operating table 1. A servo motor 2 is fixedly connected to the inner top wall of the operating table 1. A turntable 3 that fits against the top of the operating table 1 is fixedly connected to the output end of the servo motor 2. A semi-circular positioning groove 13 is provided on the top of the operating table 1. A matching positioning rod 14 is fitted to the inner wall of the semi-circular positioning groove 13. The top end of the positioning rod 14 is fixedly connected to the bottom of the turntable 3.

[0046] In this invention, the semi-circular positioning groove 13 and the fitting positioning rod 14 designed on the top of the operating table 1 are designed according to the angle of each forward or reverse rotation of the turntable 3 driven by the No. 1 servo motor 2. This ensures that the turntable 3 moves smoothly along the top of the operating table 1, which helps to improve the stability of the turntable 3 in use.

[0047] Example 6:

[0048] Reference Figure 1 and Figure 4 A performance testing device for textile yarn products includes a concave operating table 1. A first servo motor 2 is fixedly connected to the inner top wall of the operating table 1. A turntable 3, which fits against the top of the operating table 1, is fixedly connected to the output end of the first servo motor 2. Two symmetrical L-shaped fixing frames 4 are fixedly connected to the top of the turntable 3. Threaded rods 5 are connected to the inner top wall of each L-shaped fixing frame 4 and the top of the turntable 3 via bearings. A square clamping rod 6 is fixedly connected to one end of the threaded rod 5 at the top of the L-shaped fixing frame 4. A corresponding transmission mechanism 7 is engaged on the surface of the square clamping rod 6. The transmission mechanism 7 includes a concave connecting frame 701. A cylinder 8 is fixedly installed on the top of the concave connecting frame 701. A second servo motor 702 is fixedly installed on the inner bottom wall of the concave connecting frame 701. A first circular gear 703 is fixedly connected to the output end of the second servo motor 702. A matching second circular gear 704 is connected to the surface of the first circular gear 703. A rotating rod 705 is fixedly connected to the bottom of the second circular gear 704. The surface of the rotating rod 705 is connected to the inner bottom wall and bottom of the concave connecting frame 701 through a bearing. The bottom end of the rotating rod 705 extends to the bottom of the concave connecting frame 701 and is provided with a square slot 706 corresponding to the square locking rod 6 for limiting. A T-shaped mounting plate 9 is threadedly connected to the surface of the threaded rod 5. A tension gauge 10 is fixedly connected to the surface of the T-shaped mounting plate 9. A clamping assembly 11 connected to the top of the turntable 3 is provided below the tension gauge 10. A connecting limiting slide groove 15 is provided on the inner side wall of the L-shaped fixing frame 4. A limiting slide plate 16 is slidably connected to the inner wall of the limiting slide groove 15. One side of the limiting slide plate 16 is fixedly connected to the corresponding side of the T-shaped mounting plate 9.

[0049] In this invention, when the transmission mechanism 7 drives the threaded rod 5 to rotate, in order to ensure that the T-shaped mounting plate 9 with the surface thread design can move vertically up and down along the surface of the threaded rod 5 smoothly, a connecting limiting groove 15 is designed on the inner side wall of the L-shaped fixing frame 4 and it fits against the limiting slide plate 16 fixed on the surface of the T-shaped mounting plate 9. This allows the T-shaped mounting plate 9 to smoothly drive the tension gauge 10 and the textile yarn fixed between the clamping assembly 11 to perform stable tensile testing as the threaded rod 5 rotates and is limited by the sliding of the limiting slide plate 16 and the limiting groove 15.

[0050] The present invention also provides a testing method for a performance testing device for textile yarn products, comprising the following steps:

[0051] Step A: First, fix one end of the tested textile yarn to the pull ring designed at the bottom of the tensile tester 10, and fix the other end to the clamping assembly 11. Then, the cylinder 8 drives the concave connecting frame 701 in the transmission mechanism 7 to make a vertical downward linear movement, so that the square slot 706 designed at the bottom of the rotating rod 705 fits and engages with the square clamping rod 6 connected to the top of the corresponding threaded rod 5 below. When the second servo motor 702 drives the first circular gear 703, the second circular gear 704 and the rotating rod 705 to rotate relative to each other, at this time, the threaded rod 5 can drive the T-shaped mounting plate 9 with the surface thread design to cooperate with the textile yarn fixed between the tensile tester 10 and the clamping assembly 11 to perform strength stretching under the transmission of the transmission mechanism 7.

[0052] Step B: To ensure that either of the two sets of tensioning devices designed on the top of turntable 3 can switch back and forth with the transmission mechanism 7 through the corresponding L-shaped fixing bracket 4, threaded rod 5, square clamping rod 6, T-shaped mounting plate 9, tension gauge 10, and clamping assembly 11, and to continuously test the strength of the next round of textile yarn, a servo motor 2 is designed on the top wall of the operating table 1 to rotate in conjunction with turntable 3. By rotating the servo motor 2 in both forward and reverse directions at an angle of 180 degrees each time, either of the two sets of tensioning devices designed on the top of turntable 3 can be engaged with the separately designed transmission mechanism 7.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

7. The testing method of the textile yarn product performance testing device according to claim 1, characterized in that, Includes the following steps: Step A: First, fix one end of the tested textile yarn to the pull ring designed at the bottom of the tensile tester, and fix the other end to the clamping assembly. Then, drive the concave connecting frame in the transmission mechanism to make a vertical downward linear movement through the cylinder, so that the square slot designed at the bottom of the rotating rod fits and engages with the square clamp connected to the top of the corresponding threaded rod below. When the second servo motor drives the first circular gear, the second circular gear and the rotating rod to rotate relative to each other, at this time, the threaded rod can drive the T-shaped mounting plate with the surface thread design to cooperate with the textile yarn fixed between the tensile tester and the clamping assembly to perform strength stretching under the transmission mechanism. Step B: To ensure that either of the two sets of tensioning devices designed on the top of the turntable can efficiently switch back and forth with the transmission mechanism through the corresponding L-shaped fixing bracket, threaded rod, square clamping rod, T-shaped mounting plate, tension gauge, and clamping assembly, and to continuously test the strength of the next round of textile yarn, a servo motor is designed on the top wall of the operating table 1 to rotate in conjunction with the turntable. By rotating the servo motor in both forward and reverse directions by 180 degrees each time, either of the two sets of tensioning devices designed on the top of the turntable can be efficiently engaged with the separately designed transmission mechanism.
