Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, and in particular to a fabric elasticity testing device. Background Technology

[0002] In today's booming textile and apparel industry, the performance of fabrics directly impacts product quality and market competitiveness. As consumers increasingly demand greater comfort in clothing, fabric elasticity has become a key indicator. Traditional textile processes primarily measure fabrics by their static physical properties, focusing only on basic strength and color. However, in real-world applications, frequent human movement necessitates clothing that stretches and bends with the body. Early lack of precise elasticity testing methods led to many garments becoming loose and deformed after only a few wears, affecting both aesthetics and durability. Therefore, a fabric elasticity testing device has been proposed.

[0003] Traditional testing devices directly test the elasticity of fabrics, but without considering actual use, the data does not match the actual application scenarios of the fabric. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fabric elasticity testing device, which aims to improve the problem that the data does not match the actual use scenario of the fabric when testing is not performed in accordance with actual use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric elasticity testing device, comprising a worktable, a fixed bracket fixedly connected to the lower surface of the worktable, a motor fixedly connected inside the fixed bracket, a Z-shaped column provided at the output end of the motor, a limit frame slidably connected to the outer wall of the Z-shaped column, a rack plate fixedly connected to the outer wall of the limit frame, fixed columns fixedly connected to both sides of the lower surface of the rack plate, ball bearings rotatably connected to the outer wall of the fixed columns, a slide rail rotatably connected to the outer wall of the ball bearings, the slide rails fixedly connected to both sides of the lower surface of the worktable, a rotating column fixedly connected to the lower surface of the worktable, a gear rotatably connected to the outer wall of the rotating column, the gear teeth meshing with the tooth ends of the rack plate on both sides, a connecting rod fixedly connected to the outer wall of the rack plate, a lower clamping plate fixedly connected to the outer wall of the connecting rod, and a testing component provided on the outer wall of the worktable, the testing component being used to test the elasticity strength of the fabric.

[0006] Preferably, the detection component includes a baffle, a support bracket is fixedly connected to the outer wall of the baffle, and a detection mechanism is slidably connected to the outer wall of the support bracket. The detection mechanism includes an electric push rod and a force-measuring anchor rod.

[0007] Preferably, a limit rod is slidably connected to the inner wall of the lower clamping plate, and the outer wall of the limit rod is fixedly connected to the upper surface of the workbench.

[0008] Preferably, support columns are fixedly connected to both sides of the upper surface of the lower clamping plate, and limit plates are fixedly connected to the outer walls of the support columns.

[0009] Preferably, the limiting plate has an internal threaded connection to a threaded rod, and one end of the threaded rod is fixedly connected to a rotating disk.

[0010] Preferably, a pad is fixedly connected to the end of the threaded rod away from the rotating disk, and a collar is rotatably connected to the outer wall of the pad.

[0011] Preferably, an upper clamping plate is fixedly connected to the lower surface of the collar, and a grooved plate is fixedly connected to the lower surface of the upper clamping plate.

[0012] Preferably, the outer wall of the grooved plate is attached to the upper surface of the lower clamping plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the starting motor drives the Z-shaped column to move in a uniform circular motion, which in turn drives the frame to move back and forth, causing the rack plate to move the fixed column. The ball rolls on the slide rail to ensure the movement of the rack plate, so that the gear rotates and drives the lower clamping plates on both sides to move back and forth along the outer wall of the limiting rod, thereby realizing multiple cycles of stretching of the fabric, so that the stretching data is highly consistent with the actual use scenario of the fabric.

[0015] 2. In this utility model, the fabric to be tested is placed stably on the upper surface of the lower clamping plate to ensure that it is flat and wrinkle-free. Then, the worker manually rotates the rotating disk, which drives the threaded rod to rotate. Because the threaded rod is threadedly connected to the limiting plate, it will move downward along the axis when rotating, thereby driving the pad nested in the collar to move downward. Finally, the groove plate and the lower clamping plate firmly clamp the fabric to prevent deviation of the test data. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a fabric elasticity testing device, comprising a worktable 1, a fixed support 2 fixedly connected to the lower surface of the worktable 1, a motor 3 fixedly connected inside the fixed support 2, a Z-shaped column 4 provided at the output end of the motor 3, a limit frame 5 slidably connected to the outer wall of the Z-shaped column 4, a rack plate 6 fixedly connected to the outer wall of the limit frame 5, fixed columns 7 fixedly connected to both sides of the lower surface of the rack plate 6, ball bearings 8 rotatably connected to the outer wall of the fixed columns 7, a slide rail 9 rotatably connected to the outer wall of the ball bearings 8, the slide rail 9 fixedly connected to both sides of the lower surface of the worktable 1, a rotating column 11 fixedly connected to the lower surface of the worktable 1, a gear 10 rotatably connected to the outer wall of the rotating column 11, the tooth ends of the gear 10 meshing with the tooth ends of the rack plate 6 on both sides, a connecting rod 12 fixedly connected to the outer wall of the rack plate 6, a lower clamping plate 16 fixedly connected to the outer wall of the connecting rod 12, and a testing component provided on the outer wall of the worktable 1 for testing the elastic strength of the fabric.

[0025] Specifically, once the fabric is fixed, the motor 3 built into the fixing bracket 2 is activated. The motor 3 starts running, driving the Z-shaped column 4 to perform uniform circular motion around its axis. The outer wall of the Z-shaped column 4 is in contact with the inner wall of the limiting frame 5, which in turn drives the limiting frame 5 to reciprocate. The movement of the limiting frame 5 further drives the rack plate 6 to move synchronously, causing the fixing column 7 to shift. One end of the fixing column 7 is equipped with a ball bearing 8. When the fixing column 7 moves, the ball bearing 8 will roll and rotate within the slide rail 9, ensuring that the rack plate 6 moves in a precise direction and maintains a constant position. This ensures that the rack plate 6 can slide smoothly and without obstruction, and also ensures that the rack plate 6... The tooth tip can always mesh tightly with the gear 10 without any tooth disengagement, thereby driving the gear 10 to rotate. The rotating column 11 serves as the support structure for the gear 10, providing a solid fulcrum for rotation. Due to the meshing transmission characteristics of the gear 10, the rack plate 6 on the opposite side will move in a uniform linear motion in the opposite direction under the drive of the gear 10, thereby driving the lower clamping plates 16 on both sides to reciprocate along the outer wall of the limiting rod 17, realizing multiple cyclic stretching operations on the fabric. It can accurately capture the elastic change law of the fabric under long-term stress, and the data obtained by the test is highly consistent with the actual use scenario of the fabric.

[0026] Reference Figure 1 The detection component includes a baffle 13, a support bracket 14 is fixedly connected to the outer wall of the baffle 13, and a detection mechanism 15 is slidably connected to the outer wall of the support bracket 14. The detection mechanism 15 includes an electric push rod and a force measuring anchor rod.

[0027] Specifically, after the fabric completes the back-and-forth stretching process, the sliding detection mechanism 15 is moved manually or via the automated control system to a pre-set appropriate position. The electric push rod inside the detection mechanism 15 is then activated, pushing the force-measuring anchor rod slowly towards the fabric surface until it finally makes close contact with the fabric surface. Subsequently, the electric push rod continues to apply force, driving the force-measuring anchor rod to press down steadily. The entire pressing process is precisely monitored and controlled. When the predetermined standard pressure value is reached, the electric push rod automatically stops, ensuring that the force-measuring anchor rod adheres to the fabric in a precise and stable state, laying the foundation for obtaining accurate fabric stress data subsequently.

[0028] Reference Figures 1-5A limit rod 17 is slidably connected to the inner wall of the lower clamping plate 16, and the outer wall of the limit rod 17 is fixedly connected to the upper surface of the worktable 1. Support columns 18 are fixedly connected to both sides of the upper surface of the lower clamping plate 16, and a limit plate 19 is fixedly connected to the outer wall of the support columns 18. A threaded rod 20 is threadedly connected to the inside of the limit plate 19, and a rotating disk 21 is fixedly connected to one end of the threaded rod 20. A pad 22 is fixedly connected to the end of the threaded rod 20 away from the rotating disk 21, and a collar 23 is rotatably connected to the outer wall of the pad 22. An upper clamping plate 24 is fixedly connected to the lower surface of the collar 23, and a grooved plate 25 is fixedly connected to the lower surface of the upper clamping plate 24. The outer wall of the grooved plate 25 fits against the upper surface of the lower clamping plate 16.

[0029] Specifically, the fabric to be tested is placed smoothly on the upper surface of the lower clamping plate 16, ensuring the fabric is flat and wrinkle-free. Then, the worker manually rotates the rotating disk 21, transmitting its rotational motion to the threaded rod 20, causing the threaded rod 20 to rotate synchronously. Since the threaded rod 20 and the limiting plate 19 are tightly connected via a threaded structure, according to the principle of threaded transmission, the threaded rod 20 will move downwards along the axial direction during rotation. The support column 18 serves as a stable support structure for the limiting plate 19, ensuring that the limiting plate 19 remains fixed in the vertical direction, providing a stable support for the downward movement of the threaded rod 20. The obstruction causes the pad 22 to move downwards simultaneously. It is worth noting that the pad 22 is nested inside the collar 23, forming a rotatable fit between the two. When the pad 22 moves downwards, it rotates inside the collar 23. This ingenious design structure can effectively prevent the collar 23 from rotating due to the movement of the pad 22. Finally, the groove plate 25 fits tightly against the lower clamping plate 16, firmly clamping and fixing the fabric placed therein. This clamping and fixing method can effectively prevent deviations in the test data caused by the fabric sliding or displacement during subsequent testing.

[0030] Working principle: When this device is needed, first place the fabric to be tested on the upper surface of the lower clamping plate 16. Then, the worker manually rotates the rotating disk 21, causing the threaded rod 20 to rotate. Since the threaded rod 20 and the limiting plate 19 are threadedly connected, the threaded rod 20 rotates downward. The support column 18 supports and fixes the limiting plate 19. When the threaded rod 20 rotates downward, it also drives the pad 22 to move downward and rotate inside the collar 23. This causes the collar 23 to drive the upper clamping plate 24 and the grooved plate 25 to move downward. It is worth noting that when the pad 22 pushes the collar 23 downward, the pad 22 rotates inside the collar. The internal rotation of plate 23 ensures that the upper clamping plate 24 does not rotate, thereby allowing the grooved plate 25 to clamp and fix the fabric on the lower clamping plate 16. This prevents inaccurate test data due to fabric slippage during testing. Once the fabric is fixed, the motor 3 inside the fixing bracket 2 is activated. The motor 3 drives the Z-shaped column 4 to perform circular motion, causing the Z-shaped column 4 to slide on the inner wall of the limiting frame 5 and push the limiting frame 5 to move. The movement of the limiting frame 5 drives the rack plate 6 to move, which in turn drives the fixing column 7 connected to the rack plate 6 to move. The movement of the fixing column 7 causes the ball bearing 8 to rotate inside the slide rail 9, ensuring that the direction and position of the rack plate 6 are fixed. To ensure smooth sliding of the rack plate 6, the toothed ends of the rack plate 6 can tightly mesh with the gear 10. When the rack plate 6 moves, it drives the gear 10 to rotate on the outer wall of the rotating column 11. The rotating column 11 supports the gear 10, which in turn drives the rack plate 6 on the other side to move in the opposite direction. This causes the rack plates 6 on both sides to drive the connecting rod 12 to move, which in turn drives the lower clamping plate 16 to move on the outer wall of the limiting rod 17 fixed by the worktable 1. The limiting rod 17 ensures that the direction of displacement of the lower clamping plate 16 is constant. After the back-and-forth stretching is completed, the detection mechanism 15, which is supported by the baffle 13 and the support bracket 14, slides to the appropriate position and then starts the detection mechanism 1. 5. The internal electric push rod drives the force-measuring anchor rod to contact the surface of the fabric and continuously presses down until the standard pressure is reached and stops. By repeatedly stretching the fabric, the elastic change law of the fabric under long-term stress is accurately obtained. This makes the test results more consistent with the actual application performance of the fabric and provides highly valuable data for the quality assessment of the fabric. It allows manufacturers to know in advance the degree of performance degradation of the fabric after multiple uses. In other words, this device not only ensures that the test data is not inaccurate due to fabric slippage, but also achieves the effect of accurately obtaining the elastic change law of the fabric under long-term stress through repeated stretching of the fabric.
