Description

Technical Field

[0001] This invention relates to the field of fabric tensile testing technology, specifically to an intelligent testing device and method for dynamic tensile strength of textile fabrics. Background Technology

[0002] Tensile strength testing of textile fabrics is a core method for evaluating the mechanical properties of fabrics, and its results directly affect multiple stages of garment production, including quality control, product development, and trade acceptance. Currently, the tensile strength testing equipment commonly used in the textile industry is primarily based on a single-station intermittent testing mode, meaning that after each test, the sample needs to be manually replaced before the next test can be performed. This traditional testing method has revealed a series of technical shortcomings in practical applications.

[0003] First, the existing equipment has low testing efficiency, making it difficult to meet the actual needs of large-scale, continuous production in the current textile industry. Due to the long preparation time between tests, the testing process often becomes a bottleneck restricting overall production efficiency. Especially in scenarios requiring large-scale sampling inspections, frequent manual operations not only prolong the testing cycle but also fail to effectively coordinate with the production rhythm.

[0004] Secondly, the existing testing process involves numerous manual interventions, making it difficult to guarantee the consistency of test results. Factors such as the cutting size of the sample, the control of pre-tension during clamping, and the centering accuracy of the clamping position all heavily rely on the operator's experience and judgment. Different operators, or even the same operator performing the operation at different times, can introduce significant differences, leading to increased dispersion in the test results. This is particularly true for new fabric materials where there is no reference data; when conducting tensile force tests, the influence of human error easily results in data deviations.

[0005] Furthermore, according to relevant standards, warp and weft tensile tests require the cutting of specimen strips in different directions, and at least multiple valid specimens are needed for each direction to obtain statistically significant results. However, existing equipment can only test specimens in a single direction sequentially. Completing a batch of complete warp and weft tests often requires multiple shutdowns, roll changes, and re-clamping, making the process cumbersome and time-consuming. This requirement for separate sample preparation for warp and weft tests further exacerbates the complexity and inefficiency of the testing process. Summary of the Invention

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-14 The present invention provides a technical solution: a smart detection device and method for dynamic tensile strength of textile fabrics, including a first mounting bracket 1, an mounting plate 2 fixedly mounted on the first mounting bracket 1, a first movable groove 3 opened on the mounting plate 2, and a first slider 4 movably disposed in the first movable groove 3;

[0042] The testing mechanism 5 includes a first clamping block 501 and a second clamping block 502. There are two sets of first clamping blocks 501. One set of first clamping blocks 501 is fixedly installed on the mounting plate 2, and the other set of first clamping blocks 501 is fixedly installed on the first slider 4. The second clamping block 502 is movably installed on each of the first clamping blocks 501.

[0043] The winding mechanism 6 includes a second mounting bracket 601, a hollow winding roller 603, and a pressing rod 612. The second mounting bracket 601 is movably mounted on the upper end of the mounting plate 2. Two sets of hollow winding rollers 603 are rotatably mounted on the second mounting bracket 601. Four sets of pressing rods 612 are provided on one side of the second mounting bracket 601.

[0044] The traction mechanism 7 includes a traction rod 708 and a pressure plate 711. The traction rod 708 is movably mounted on the mounting plate 2, and the pressure plate 711 is rotatably mounted on the traction rod 708.

[0045] This equipment achieves highly intelligent detection of fabric tensile strength through automated fabric cutting, traction, detection, and switching. It can significantly save the time of manual reloading in the traditional detection process. At the same time, by using automated traction to replace manual loading, it can greatly reduce the errors that may occur during manual loading.

[0046] Furthermore, the detection mechanism 5 also includes a mounting box 503, a second movable groove 504, a second slider 505, a first threaded sleeve 506, a first motor 507, a first screw 508, a telescopic motor 509, a tension sensor 510, a mounting hole 511, a drag-reducing ring 512, and a first guide rod 513. A mounting box 503 is fixedly mounted on one side of the first clamping block 501. A second movable groove 504 is formed inside the mounting box 503, and a second slider 505 is movably inserted into the second movable groove 504. The second slider 505 is fixedly mounted on the second clamping block 502. A first threaded sleeve 506 is fixedly mounted at the center of the second slider 505. A first motor 507 is fixedly mounted on one side of the mounting box 503. A first screw 508 is fixedly mounted on the output shaft of the first motor 507. The first threaded sleeve 506... 06 is threaded onto the first screw 508, which is rotatably mounted in the second movable groove 504. The length of the first clamping block 501 is equal to the length of the second clamping block 502. The length of the first clamping block 501 is adapted to the width of the mounting plate 2. The shapes of the opposite surfaces of the first clamping block 501 and the second clamping block 502 match. A telescopic motor 509 is fixedly mounted on the lower end of the mounting plate 2. A tension sensor 510 is fixedly mounted on the output shaft of the telescopic motor 509. The tension sensor 510 is fixedly mounted on the first slider 4. Two sets of mounting holes 511 are opened on the first slider 4. A drag-reducing ring 512 is fixedly mounted in the mounting holes 511. Two sets of first guide rods 513 are fixedly mounted in the first movable groove 3. The drag-reducing ring 512 is movably sleeved on the first guide rod 513. This structure is a fabric clamping structure. The relative movement and stretching of the second clamping block 502 and the first clamping block 501 are existing mature technologies. The feature is that the distance between the first clamping block 501 and the second clamping block 502 allows the traction rod 708 to pass through, which provides the necessary conditions for the subsequent automated traction of the fabric. At the same time, the movement of the second clamping block 502 also provides a power source for the subsequent automatic cutting of the fabric.

[0047] Furthermore, the testing mechanism 5 also includes a mounting plate 514, a receiving seat 515, a cutting groove 516, a cutting blade 517, a third movable groove 518, a first movable rod 519, a first spring 520, and a pressing side plate 521. A receiving seat 515 is fixedly mounted on one side of the first clamping block 501, which is fixedly mounted on the mounting plate 2. A mounting plate 514 is fixedly mounted on a second clamping block 502, which is located on the first clamping block 501. A cutting blade 517 is mounted on the mounting plate 514. The position of the cutting blade 517 is aligned with the position of the cutting groove 516. The mounting plate 514 is symmetrically provided with four sets of third movable slots 518. A first movable rod 519 is movably inserted into the third movable slot 518. A first spring 520 is provided in the third movable slot 518. One side of the first movable rod 519 abuts against the first spring 520. The same set of pressing side plates 521 are fixedly installed on the two sets of first movable rods 519. The two sets of pressing side plates 521 are located on both sides of the cutting blade 517. The receiving seat 515 and the first clamping block 501 fixed on the first slider 4 have a uniformly inclined surface on the side near the hollow winding roller 603. This structure is a fabric cutting structure. When the second clamping block 502 descends, the pressing side plate 521 contacts the fabric first, which fixes the fabric between the receiving seat 515 and the pressing side plate 521. In this way, the fabric can be directly cut when the first clamping block 501 and the second clamping block 502 are fully engaged. For fabrics with high elasticity and high toughness, the cutting blade 517 may not be able to cut it, but it does not affect the test. Because the fabric is fixed on both sides during the test, the length of the part of the fabric outside the fixed part does not affect the test results. Moreover, high toughness and high elasticity fabrics are generally tested for elasticity and will not be torn. The continuity of traction can be guaranteed. If a breakage test is required, a different cutting blade 517 can be replaced to ensure that the cutting function can be completed. Since the replacement of the cutting blade 517 is a conventional technology, it will not be designed or described here. The inclined surface design of the first clamping block 501 and the receiving seat 515 provides guiding conditions for the subsequent movement of the traction rod 708.

[0048] Furthermore, the winding mechanism 6 also includes a mounting ring 602, a shifting ring 604, a first rotating disc 605, a locking groove 606, a fixing rod 607, a clamping arc-shaped block 608, a first torsion spring 609, and a finger groove 610. The mounting ring 602 is fixedly mounted at the center of the second mounting bracket 601. One end of the hollow winding roller 603 is fixedly mounted with the shifting ring 604, and the other end of the hollow winding roller 603 is fixedly mounted with the first rotating disc 605. The shifting ring 604 is rotatably mounted on the second mounting bracket 601, and the first rotating disc 605 is rotatably mounted on the mounting ring 602. Inside the 2nd section, a locking groove 606 is provided on the hollow take-up roller 603. A fixing rod 607 is fixedly installed between the actuating ring 604 and the first rotating disc 605. A clamping arc block 608 is rotatably installed on the fixing rod 607. The shape of the clamping arc block 608 is adapted to the shape of the locking groove 606, and one end abuts against one end of the locking groove 606. A first torsion spring 609 is provided inside the clamping arc block 608. One end of the first torsion spring 609 is fixedly installed on the fixing rod 607, and the other end is fixedly installed inside the clamping arc block 608. A finger groove 610 is provided on the clamping arc block 608. The hollow take-up roller 603 is used to take up the fabric, while the clamping arc block 608 is used to clamp the end of the fabric. Although the clamping arc block 608 can clamp the fabric, under the traction of the traction mechanism 7, the fabric can still be pulled out from the locking groove 606, so that the fabric can be completely separated from the locking groove 606, and the previous set of fabric will not affect the loading of the next set of fabric.

[0049] Furthermore, the winding mechanism 6 also includes fixed side plates 611, pressing rods 612, a fourth movable groove 613, a guide hole 614, a second guide rod 615, a second return spring 616, a rotating ring 617, and a first damping rubber ring 618. Four sets of fixed side plates 611 are fixedly installed on the second mounting bracket 601 and the mounting ring 602. Two sets of pressing rods 612 are provided on two sets of fixed side plates 611. One set of pressing rods 612 is fixedly installed between the two sets of fixed side plates 611, and both ends of the other set of pressing rods 612 are provided with guides. A fourth movable groove 613 is provided on both the guide hole 614 and the fixed side plate 611. A second guide rod 615 is fixedly installed in the fourth movable groove 613. The second guide rod 615 is inserted into the guide hole 614. A second return spring 616 is sleeved on the second guide rod 615. One end of the second return spring 616 abuts against the end of the pressing rod 612, and the other end abuts against the inside of the fourth movable groove 613. A rotating ring 617 is rotatably installed on the pressing rod 612. A first damping rubber ring 618 is fixedly installed on the rotating ring 617. This structure is used to fix the end of the fabric, so that the end of the fabric can remain flat and stable. At the same time, the pressing force of the fabric end itself and the winding force of the hollow take-up roller 603 on the fabric are balanced, so that the fabric can remain taut and reduce the adverse effects of inaccurate positioning and movement obstruction caused by loose fabric.

[0050] Furthermore, the winding mechanism 6 also includes a second rotating disc 619, a second damping rubber ring 620, a mounting groove 621, a rotating rod 622, a second torsion spring 623, a reset block 624, a low-resistance rubber ring 625, a high-resistance rubber ring 626, a mounting frame 627, a drive motor 628, an adjusting screw 629, a positioning block 630, and an adjusting screw sleeve 631. The second rotating disc 619 is fixedly mounted on the actuating ring 604. The second rotating disc 619 is rotatably mounted on the second mounting bracket 601. The second damping rubber ring 620 is fixedly mounted on the second rotating disc 619. Mounting grooves 621 are provided on both sides of the second mounting bracket 601. A rotating rod 622 is rotatably mounted in the mounting groove 621. A second torsion spring 623 is provided on the rotating rod 622. One end of the 3 is fixedly installed on the rotating rod 622 and the other end is fixedly installed on the inner wall of the mounting groove 621. A low-resistance rubber ring 625 and a high-resistance rubber ring 626 are fixedly installed on the rotating rod 622. The high-resistance rubber ring 626 is in contact with the second damping rubber ring 620. A mounting frame 627 is fixedly installed on the second mounting bracket 601. A drive motor 628 is fixedly installed on one end of the mounting frame 627. An adjusting screw 629 is fixedly installed on the output shaft of the drive motor 628. The adjusting screw 629 is rotatably installed in the mounting frame 627. A positioning block 630 is fixedly installed on the upper end of the mounting plate 2. An adjusting screw sleeve 631 is fixedly installed in the mounting frame 627. The positioning block 630 is slidably installed in the mounting frame 627. The adjusting screw sleeve 631 is threaded onto the adjusting screw 629. The structure provides resistance to the rotation of the hollow take-up roller 603. The feature is that the reset block 624 itself can provide a certain resistance to the rotation of the hollow take-up roller 603, which can be balanced with the clamping force provided by the above structure. After the fabric is pulled, the hollow take-up roller 603 will be reversed by a certain angle due to the change of friction and the reset of the second torsion spring 623, thereby further straightening the fabric and increasing the stability and functionality of the equipment. The displacement of the second mounting bracket 601 can be realized through the drive motor 628 and other structures.

[0051] Furthermore, the traction mechanism 7 also includes a rack 701, a locking slider 702, a second motor 703, a first gear 704, a limiting clamp 705, a third motor 706, a second gear 707, a limiting groove 709, and a toothed groove 710. A rack 701 is fixedly mounted on one side of the mounting plate 2. A locking slider 702 is slidably mounted on the rack 701. A second motor 703 is fixedly mounted on the locking slider 702. A first gear 704 is fixedly mounted on the output shaft of the second motor 703. The first gear 704 interacts with the rack. The traction rod 701 is engaged, and the locking slider 702 is provided with two sets of limiting clamps 705. The traction rod 708 is provided with two sets of limiting grooves 709. The ends of the limiting clamps 705 slide within the limiting grooves 709. A third motor 706 is fixedly installed on one set of limiting clamps 705. A second gear 707 is fixedly installed on the output shaft of the third motor 706. The second gear 707 is rotatably installed between the two sets of limiting clamps 705. A toothed groove 710 is arrayed on one side of the traction rod 708, and the second gear 707 meshes with the toothed groove 710. This structure is the driving structure of the traction rod 708. This structure allows the traction rod 708 to perform a U-shaped movement. When the fabric is fixed for detection by the detection mechanism 5, the traction rod 708 can be moved to the right to create space and reset, and then the cut end can be clamped. This method can ensure the continuity of the fabric during the tear-type detection process and increase the stability of the equipment during use.

[0052] Furthermore, the traction mechanism 7 also includes a fourth motor 712, which is fixedly mounted on the traction rod 708. The output shaft of the fourth motor 712 is connected to one end of the pressure plate 711. The pressure plate 711 is elastic, and its length is adapted to the length of the traction rod 708. This structure is a fabric fixing structure. The fabric end can be fixed by the fit between the pressure plate 711 and the traction rod 708. The feature is that the friction between the pressure plate 711 and the fabric can be increased according to the rotation angle and deformation of the pressure plate 711, thereby adapting to the force required to completely pull out the fabric.

[0053] Furthermore, the traction mechanism 7 also includes a connecting arc block 713, a fifth movable groove 714, a second movable rod 715, and a second spring 716. A connecting arc block 713 is fixedly installed between the two sets of limiting clamps 705. Each limiting clamp 705 has a fifth movable groove 714, and a second movable rod 715 is movably inserted into the fifth movable groove 714. The second movable rods 715 are all fixedly installed on the engaging slider 702, and each second movable rod 715 is fitted with a second spring 716. This structure is the movable structure of the traction rod 708, allowing the fabric pulled by the traction rod 708 to be laid and adhered to the first clamping block 501, avoiding partial folding caused by the fabric being suspended in the air, and also preventing wrinkles in the fabric, thus increasing the stability of the equipment during use.

[0054] Furthermore, S1: Cut the fabric into strips of appropriate width, cut one strip each according to the warp and weft directions of the fabric, load the two sets of strips onto the hollow take-up roller 603, and clamp the ends between the two sets of first damping rubber rings 618.

[0055] S2: Manually pull the fabric between the pressure plate 711 and the traction rod 708 for clamping. The traction rod 708 moves relative to the mounting plate 2 and passes through the gap between the first clamping block 501 and the second clamping block 502, so that the fabric is placed on the first clamping block 501. The second clamping block 502 descends to clamp the fabric and cuts the fabric.

[0056] S3: The pressure plate 711 releases the fabric and clamps the cut fabric end through its own movement to reset. After the traction rod 708 resets, the telescopic motor 509 starts to perform a stretch test on the fabric.

[0057] S4: When switching fabrics with different cutting methods, the tested fabric is completely pulled out by the traction mechanism 7. After the traction mechanism 7 is reset, the end of the second set of fabrics is moved laterally between the traction rod 708 and the pressure plate 711 by moving the second mounting bracket 601.

[0058] Working principle: When using this invention, the fabric needs to be cut first into strips of appropriate width. One strip is cut according to the warp and weft directions of the fabric. Then, the clamping arc block 608 is rotated by the finger groove 610. At this time, the first torsion spring 609 stores energy, and the end of the fabric is placed flat in the locking groove 606. Then, the clamping arc block 608 is released. Under the action of the first torsion spring 609, the clamping arc block 608 resets and clamps the fabric. The fabric is then wound onto the hollow take-up roller 603. The movable pressing rod 612 is pulled, which stores energy in the second return spring 616. One end of the fabric is placed flat between the two sets of first damping rubber rings 618. The pressing rod 612 is released, and the second return spring 616 springs back to clamp the first damping rubber rings 618, thus fixing the fabric.

[0059] When fabric needs to be tested, the fabric to be tested is pulled. At this time, the hollow take-up roller 603 rotates, driving the second rotating disk 619 to rotate. The reset block 624 is driven to rotate by the friction between the high-resistance rubber ring 626 and the second damping rubber ring 620, causing the second torsion spring 623 to store energy. Until the low-resistance rubber ring 625 contacts the second damping rubber ring 620, the friction decreases, and the reset block 624 is in a critical state where the second torsion spring 623 stores energy and the reset block 624 does not rotate under the action of the fabric still being pulled. If the fabric is not pulled, the reset block 624 will not rotate. 4 will reverse under the action of the second torsion spring 623. The friction between the high-resistance rubber ring 626 and the second damping rubber ring 620 will cause the second rotating disk 619 to reverse, thereby achieving the straightening of the fabric. At this time, the traction mechanism 7 is at the upper end of the mounting plate 2, pulling the end of the fabric between the pressure plate 711 and the traction rod 708. The fourth motor 712 is started, causing the pressure plate 711 to rotate, clamping the fabric between the pressure plate 711 and the traction rod 708. Then, the second motor 703 is started to drive the first gear 704 to rotate. The rotation of the first gear 704 interacts with the rack 701. The meshing between the two drives the structure set on the engaging slider 702 to move. At this time, the traction rod 708 moves downward and moves under the guidance of the shape of the receiving seat 515, so that the limiting clamping block 705 moves relative to the engaging slider 702. At this time, the second movable rod 715 moves in the fifth movable groove 714 and compresses the second spring 716, so that the fabric can adhere to the surface of the first clamping block 501 during the undulating process. After the traction rod 708 passes through the two sets of first clamping blocks 501, the second clamping block 502 moves and presses against the first clamping block 501 to clamp the fabric. The output shaft of the first motor 507 rotates, driving the first screw 508 to rotate. This, in turn, drives the second slider 505 to move through the thread action between the first screw sleeve 506 and the first screw 508, which in turn drives the second clamping block 502 to move. During the downward movement of the second clamping block 502, the pressing side plate 521 will first contact the fabric and press it onto the receiving seat 515. When the second clamping block 502 is completely in contact with the first clamping block 501, the cutting blade 517 cuts the fabric. At this time, the cut fabric is still pressed between the pressing side plate 521 and the receiving seat 515.

[0060] When the first clamping block 501 and the second clamping block 502 are fully engaged, the pressure plate 711 rotates to release the fabric. Then, the third motor 706 starts and drives the second gear 707 to rotate. Through the meshing with the tooth groove 710, the traction rod 708 moves, so that the traction rod 708 is no longer in front of the mounting plate 2. Then, the second motor 703 starts and resets the locking slider 702. The third motor 706 starts and resets the traction rod 708. At this time, the end of the fabric wound on the hollow take-up roller 603 is between the pressure plate 711 and the traction rod 708, completing one cycle. At this time, the telescopic motor 509 stretches the first slider 4. The first slider 4 slides in the mounting plate 2. Fabric stretch detection can be achieved through the telescopic motor 509 and the tension sensor 510. The detection principle is a mature existing technology and will not be described in detail here.

[0061] After a section of fabric is inspected, the remaining section of fabric is completely pulled out so that the fabric is completely detached from the hollow take-up roller 603. Then, the drive motor 628 is started, and the second mounting bracket 601 is moved by the thread action between the adjusting sleeve 631 and the adjusting screw 629, so that the end of the next set of fabric can be inserted between the traction rod 708 and the pressure plate 711.
