Description

Technical Field

[0001] This invention belongs to the technical field of fabric testing equipment, and in particular relates to a device for testing the tensile strength of textile fabrics. Background Technology

[0002] Textile fabrics are soft, thin sheets of material made from fibers through processes such as spinning, weaving, or knitting, and are widely used in clothing, home textiles, and industrial sectors. Their core components are natural fibers (cotton, linen, silk, wool) and chemical fibers (polyester, nylon, acrylic, etc.). Based on processing methods, they can be divided into woven fabrics (such as shirt fabric), knitted fabrics (such as T-shirt fabric), and nonwoven fabrics (such as nonwoven fabrics). Tensile testing of textile fabrics is a core test for evaluating the mechanical properties of materials, used to determine the strength and deformation characteristics of the fabric under axial tensile force. Its principle follows Hooke's Law and the mechanical properties of materials, and the main indicators include breaking strength (the maximum force required for the fabric to break) and elongation at break (the percentage change in length when stretched to break).

[0003] A Chinese patent application (or patent) with publication number CN221622791U discloses a device for testing the tensile strength of textile fabrics, comprising: a base plate, wherein a pore density testing mechanism, a tensile strength testing mechanism, and a data adjustment mechanism are respectively mounted on the top of the base plate; the pore density testing mechanism comprises two support plates A, and a material placement plate A is installed between the two support plates A; the tensile strength testing mechanism comprises two main support plates B, and a material placement plate B is installed between the two main support plates B, wherein the material placement plate B is equipped with two connecting blocks.

[0004] However, the above-mentioned device still has the following problems during implementation: During fabric strength testing, two sets of clamps are fixed to both sides of the fabric. An electric telescopic rod drives the two sets of clamps to move in opposite directions to perform tensile testing on the fabric. Since the clamps only apply force along a single axis, a single test can only be performed on the transverse direction of the fabric. To obtain longitudinal data, the machine must be stopped, the clamp orientation adjusted, and the fabric repositioned and clamped. This operation is cumbersome and time-consuming, significantly reducing the overall testing efficiency.

[0005] To address this issue, we provide a textile fabric tensile strength testing device. Summary of the Invention

[0006] The purpose of this invention is to provide a textile fabric tensile strength testing device. By combining the structure of the support component, the transverse stretching component, and the longitudinal stretching component, it solves the problem in the prior art that when testing fabric strength, only the transverse side of the fabric can be tested at a time. When the longitudinal force on the fabric is applied, the direction of the clamp needs to be changed, the fabric needs to be repositioned, and a second stretching is required, which affects the fabric testing efficiency.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0008] This invention relates to a textile fabric tensile strength testing device, comprising a processing table with a placement plate on top; a support assembly on top of the processing table, the support assembly including a support plate mounted on the top of the processing table, a horizontal plate mounted on one side of the support plate, a slide rod mounted inside the horizontal plate, a movable frame slidably connected to the surface of the slide rod, and a pusher frame mounted on one side of the placement plate, which supports and flattens the fabric; a transverse stretching assembly on top of the processing table, the transverse stretching assembly including a first gear mounted at the bottom of the placement plate, two sets of toothed plates meshing on both sides of the first gear, a pusher plate mounted on one side of the toothed plates, and a first pressure sensor mounted on one side of the pusher plate. The device includes a first convex plate slidably connected to the surface of a push plate, a vertical rod slidably connected to the inside of a movable frame, a first pressure plate installed at the top of the vertical rod, and a horizontal shaft installed at the bottom of the vertical rod. A transverse stretching assembly is used to detect the transverse stretch of the fabric. A longitudinal stretching assembly is provided on one side of the push frame. The longitudinal stretching assembly includes an adjusting rod slidably connected to the inside of the push frame, a second pressure plate installed at the top of the adjusting rod, a longitudinal shaft installed at the bottom of the adjusting rod, a pulley installed on one side of a toothed plate, a trapezoidal plate slidably connected to one side of the pulley, a second pressure sensor installed on one side of the trapezoidal plate, and a second convex plate installed on one side of the second pressure sensor. The longitudinal stretching assembly is used to detect the longitudinal stretch of the fabric.

[0009] The present invention is further configured such that a drive assembly is provided on the top of the processing table, the drive assembly including a drive motor mounted on the top of the processing table, a second gear mounted on the output end of the drive motor, a drive rod mounted on the shaft of the first gear, and a third gear mounted on the surface of the drive rod.

[0010] The invention is further configured such that one side of the second gear meshes with the third gear, and the top of the drive rod is movably connected to the placement plate via a bearing.

[0011] The invention is further configured such that a first spring is sleeved on the surface of the slide bar, and one end of the first spring is fixedly connected to the movable frame.

[0012] The invention is further configured such that a support rod is slidably connected inside the support plate, one side of the support rod is fixedly connected to the push frame, and a second spring is sleeved on the surface of the support rod.

[0013] The present invention is further configured such that a first elastic sheet is fixedly connected to one side of the first pressure plate, and the bottom of the first elastic sheet is in contact with the movable frame.

[0014] The present invention is further configured such that a second elastic sheet is fixedly connected to one side of the second pressure plate, and the bottom of the second elastic sheet is in contact with the push frame.

[0015] The invention is further configured such that one side of the first convex plate contacts the horizontal axis, and one side of the first convex plate is inclined to push the horizontal axis to move downward.

[0016] The invention is further configured such that one side of the second convex plate contacts the longitudinal axis, and one side of the second convex plate is inclined to push the longitudinal axis to move downward.

[0017] The invention is further configured such that both the first and second convex plates have notches on one side, allowing the two sets of toothed plates to pass through when moving, thus avoiding interference.

[0018] The present invention has the following beneficial effects: By setting up a transverse stretching component and a longitudinal stretching component, and using the same drive motor to drive the first gear to rotate, the toothed plates are driven to move in opposite directions or towards each other, thereby realizing the transverse stretching of the first pressure plate on both sides of the fabric and the longitudinal stretching of the second pressure plate on the front and rear sides of the fabric. During the testing process, there is no need to re-clamp or adjust the fabric direction, and the transverse and longitudinal tensile strength tests can be completed alternately, which significantly improves the testing efficiency. At the same time, with the cooperation of the first pressure sensor and the second pressure sensor, the tensile force value is fed back in real time, ensuring that the test data is accurate and reliable, and solving the problem that the existing technology can only test in one direction at a time and is cumbersome to operate.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1: Please refer to Figures 1-9This invention relates to a textile fabric tensile strength testing device, comprising a processing table 1, with a placement plate 2 on top of the processing table 1; a support assembly 3 on top of the processing table 1, the support assembly 3 including a support plate 301 mounted on top of the processing table 1, a horizontal plate 302 mounted on one side of the support plate 301, a slide rod 303 mounted inside the horizontal plate 302, a movable frame 304 slidably connected to the surface of the slide rod 303, and a pusher 305 mounted on one side of the placement plate 2, the support assembly 3 providing flattening support for the fabric; a transverse stretching assembly 4 on top of the processing table 1, the transverse stretching assembly 4 including a first gear 401 mounted at the bottom of the placement plate 2, two sets of toothed plates 402 meshing on both sides of the first gear 401, a pusher 403 mounted on one side of the toothed plates 402, and a first pressure sensor 404 mounted on one side of the pusher 403, slidably connected to the pusher 405. A first convex plate 405 on the surface of the 03 is slidably connected to a vertical rod 406 inside the movable frame 304, a first pressure plate 407 installed on the top of the vertical rod 406, and a horizontal shaft 408 installed on the bottom of the vertical rod 406. The transverse stretching assembly 4 is used to detect the transverse stretch of the fabric. A longitudinal stretching assembly 5 is provided on one side of the push frame 305. The longitudinal stretching assembly 5 includes an adjusting rod 501 slidably connected to the inside of the push frame 305, a second pressure plate 502 installed on the top of the adjusting rod 501, a longitudinal shaft 503 installed on the bottom of the adjusting rod 501, a pulley 504 installed on one side of the toothed plate 402, a trapezoidal plate 505 slidably connected to one side of the pulley 504, a second pressure sensor 506 installed on one side of the trapezoidal plate 505, and a second convex plate 507 installed on one side of the second pressure sensor 506. The longitudinal stretching assembly 5 is used to detect the longitudinal stretch of the fabric.

[0033] Specifically: Placement plate 2 supports the textile fabric to be tested, keeping it flat; support plate 301 provides fixed support for the overall structure, ensuring the relative position stability of each component during testing; horizontal plate 302 provides horizontal support for slide bar 303, ensuring it remains parallel; slide bar 303 serves as a guide rail for moving frame 304, ensuring it slides smoothly in a fixed direction; moving frame 304 drives the first pressure plate 407 to move laterally, achieving lateral stretching of the fabric; push frame 305 drives the second pressure plate 502 to move longitudinally, achieving longitudinal stretching of the fabric; first gear 401 drives the two toothed plates 402 to move synchronously in opposite directions, achieving symmetrical stretching and ensuring uniform force on both sides of the fabric; toothed plates 402 convert the rotational motion of the first gear 401 into linear motion, transmitting the stretching force; push plate 403 stably transmits the moving force of toothed plates 402 to the first... A pressure sensor 404 detects the tension value during the lateral stretching process in real time and feeds it back to the control system. A first convex plate 405 pushes the horizontal shaft 408 downward through its inclined surface, realizing the clamping action of the first pressure plate 407. The vertical rod 406 transmits the downward movement of the horizontal shaft 408 to the first pressure plate 407 to complete the clamping action. The first pressure plate 407 clamps the two sides of the fabric to ensure that the fabric will not slip during lateral stretching. The horizontal shaft 408 serves as the force-bearing point of the first convex plate 405, driving the vertical rod 406 and the first pressure plate 407 to move downward. The adjusting rod 501 drives the second pressure plate 502 to move downward, realizing the longitudinal clamping of the front and rear sides of the fabric. The second pressure plate 502 clamps the front and rear sides of the fabric to ensure that the fabric is firmly fixed during longitudinal stretching. The longitudinal shaft 503 drives the adjusting rod 501 and the second pressure plate 502 to move downward, completing the longitudinal clamping action.

[0034] Example 2: Please refer to Figures 1-9 Based on Embodiment 1, a drive assembly 6 is provided on the top of the processing table 1. The drive assembly 6 includes a drive motor 601 installed on the top of the processing table 1, a second gear 602 installed on the output end of the drive motor 601, a drive rod 603 installed at the shaft of the first gear 401, and a third gear 604 installed on the surface of the drive rod 603. One side of the second gear 602 meshes with the third gear 604. The top of the drive rod 603 is movably connected to the placement plate 2 through a bearing. A first spring 7 is sleeved on the surface of the slide rod 303. One end of the first spring 7 is fixedly connected to the moving frame 304. A support rod 8 is slidably connected inside the support plate 301. One side of the support rod 8 is fixedly connected to the push frame 305. A second spring 9 is sleeved on the surface of the support rod 8.

[0035] Specifically: the pulley 504 converts the linear motion of the toothed plate 402 into the displacement of the trapezoidal plate 505. The trapezoidal plate 505 pushes the second pressure sensor 506 and the second convex plate 507 to move, realizing the power transmission of longitudinal tension. The second pressure sensor 506 detects the tension value in real time during the longitudinal tension process and feeds it back to the control system. The second convex plate 507 pushes the longitudinal shaft 503 downward through its inclined surface, realizing the longitudinal clamping of the second pressure plate 502. The drive motor 601 provides driving force. The second gear 602 transmits the power of the drive motor 601 to the third gear 604. The drive rod 603 stably transmits the power from the third gear 604 to the first gear 401. The third gear 604 meshes with the second gear 602 to realize the second stage of power transmission.

[0036] Example 3: Please refer to Figures 1-9 Based on Embodiments 1 and 2, a first elastic sheet 10 is fixedly connected to one side of the first pressure plate 407, and the bottom of the first elastic sheet 10 contacts the movable frame 304. A second elastic sheet 11 is fixedly connected to one side of the second pressure plate 502, and the bottom of the second elastic sheet 11 contacts the push frame 305. One side of the first convex plate 405 contacts the horizontal axis 408, and one side of the first convex plate 405 is inclined to push the horizontal axis 408 downward. One side of the second convex plate 507 contacts the vertical axis 503, and one side of the second convex plate 507 is inclined to push the vertical axis 503 downward. Both the first convex plate 405 and the second convex plate 507 have notches on one side to allow the two sets of toothed plates 402 to pass through when moving, thus avoiding interference.

[0037] Specifically: Both sets of toothed plates 402 have sliders fixedly connected to their bottoms. The bottoms of the sliders are slidably connected to the processing table 1, providing guide rail support for the movement of the toothed plates 402. The elastic force of the first spring 7 is greater than that of the first elastic plate 10, and the elastic force of the second spring 9 is greater than that of the second elastic plate 11. After the lateral stretching is completed, the first spring 7 helps the moving frame 304 to reset. The support rod 8 guides the pushing frame 305 to move smoothly during the longitudinal stretching process. After the longitudinal stretching is completed, the second spring 9 helps the pushing frame 305 to reset. The first elastic plate 10 provides elastic force when the first pressure plate 407 is pressed down and assists the first pressure plate 407 to reset. The second elastic plate 11 provides elastic buffer when the second pressure plate 502 is pressed down, protecting the fabric and assisting the second pressure plate 502 to reset. The notch prevents the first convex plate 405 and the second convex plate 507 from interfering with the toothed plates 402 during the movement, ensuring smooth operation of the equipment.

[0038] The working principle of this invention is as follows: the staff moves the fabric to be tested to the top of the placement plate 2 and lays it flat. At the same time, the staff manually moves the fabric so that the two sides of the fabric are placed into the bottom of the two sets of first pressure plates 407, and the front and back sides of the fabric are placed into the bottom of the two sets of second pressure plates 502, thus completing the initial positioning of the fabric.

[0039] Then, the drive motor 601 is started by the external controller. The drive motor 601, together with the second gear 602, drives the third gear 604 to rotate. The third gear 604, together with the drive rod 603, drives the first gear 401 to rotate. The first gear 401 drives the two sets of toothed plates 402 to move in opposite directions. While the toothed plates 402 are moving, they also drive the push plate 403 to move. The push plate 403 drives the first pressure sensor 404 and the first convex plate 405 to move. The first convex plate 405 contacts the horizontal shaft 408 and pushes the horizontal shaft 408 to move downward. While the horizontal shaft 408 is moving, it also drives the vertical rod 406 and the first pressure plate 407 to move downward. When the first pressure plate 407 moves downward, it clamps the two sides of the fabric to achieve the function of fixing.

[0040] Then, the drive motor 601 continues to drive the two sets of first convex plates 405 to move in opposite directions. The first convex plates 405 push the two sets of horizontal shafts 408 to move in opposite directions. The horizontal shafts 408, in conjunction with the moving frame 304, drive the first pressure plate 407 to move. When the two sets of first pressure plates 407 and horizontal shafts 408 move in opposite directions, the fabric is stretched laterally. The pressure value is fed back through the first pressure sensor 404 to obtain the lateral tensile strength data of the fabric.

[0041] When it is necessary to test the longitudinal tensile strength of the fabric, the control drive motor 601 drives the two sets of first convex plates 405 to reset to their original positions. Figure 3 The location.

[0042] Then, the drive motor 601 is controlled to rotate in the opposite direction again. The drive motor 601, in conjunction with the second gear 602, drives the third gear 604 to rotate. The third gear 604, in conjunction with the drive rod 603, drives the first gear 401 to rotate. The first gear 401 drives the two sets of toothed plates 402 to move relative to each other. As the toothed plates 402 move, they also drive the pulley 504 to move. The pulley 504 pushes the trapezoidal plate 505 to move. The trapezoidal plate 505 pushes the second pressure sensor 506 and the second convex plate 507 to move. The second convex plate 507 pushes the longitudinal shaft 503 to move downward. The longitudinal shaft 503, in conjunction with the adjusting rod 501, drives the second pressure plate 502 to move downward. When the second pressure plate 502 moves downward, it clamps the front and rear sides of the fabric, thus achieving a fixing effect.

[0043] Then, the drive motor 601 continues to drive the two sets of second convex plates 507 to move in opposite directions. While the second convex plates 507 are moving, they push the two sets of longitudinal shafts 503 to move in opposite directions. The longitudinal shafts 503, in conjunction with the push frame 305, drive the second pressure plate 502 to move. When the two sets of second pressure plates 502 and the longitudinal shafts 503 move in opposite directions, they stretch the fabric longitudinally. The pressure value is fed back by the second pressure sensor 506 to obtain the longitudinal tensile strength data of the fabric. The entire detection process can be carried out alternately without repeatedly disassembling and assembling the fixture, which effectively improves the detection efficiency of the fabric.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
