Tensile strength is a key indicator for evaluating fabric quality, especially in fields with high practical requirements, where the tensile performance of fabrics is of paramount importance, as it directly affects the safety of users.

[0003] However, while pursuing high-quality tensile strength, higher requirements are also placed on the uniformity of fabric edge clamping. If the fabric is not clamped evenly at the stress point, it will lead to uneven stress on different parts of the fabric, resulting in varying degrees of tearing. This will not only directly affect the accuracy of tensile strength test results, but may also mislead manufacturers and testing institutions in their understanding of fabric performance.

[0019] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] Against the backdrop of the rapid development of the current apparel industry, the demand for fabrics is becoming increasingly diversified and stringent, especially in fields with high safety requirements, such as the automotive and aerospace industries. With the continuous improvement of quality requirements, tensile strength, as one of the key indicators for testing fabric quality, is becoming increasingly important. High tensile strength means that the fabric can more effectively resist external forces during use, thereby ensuring the safety and comfort of the user.

[0021] However, in practical applications and quality inspection, the consistency of fabric clamping force is equally crucial. Uneven clamping force during tensile testing can lead to inconsistent tearing of the fabric under stress, directly affecting the accuracy of the test results and potentially misleading manufacturers and testing institutions' understanding of the fabric's performance. Therefore, ensuring the consistency and uniformity of clamping force is a key issue in improving the accuracy and reliability of fabric tensile testing.

[0022] To address the aforementioned technical problems, a fabric tensile strength testing device is proposed, comprising a base 100, which is set on the ground to support the entire device and ensure its stability and reliability. Clamping member 200, the clamping member 200 is disposed on the base 100, there are two clamping members 200, the two clamping members 200 move along a first direction (where the first direction is the straight line direction between the two clamping members 200); there are two clamping members 200, which can move along the first direction (i.e. the straight line direction between the clamping members 200) to fix the fabric sample to be tested.

[0023] A lifting mechanism 300 is provided on one side of the clamping member 200 to drive one or two members to move along a first direction (in this embodiment, the lifting mechanism 300 drives the clamping member 200 to move in a vertical direction). It also includes a tensile tester, which is set on the clamp 200 to detect the tensile strength of the fabric.

[0024] The lifting mechanism 300 is located on one side of the clamping member 200 and can drive the clamping member 200 to move vertically (i.e., perpendicular to the first direction), thereby adjusting the height of the clamping member 200 to accommodate fabric samples of different lengths. In summary, the working principle of this device is as follows: the base 100 provides a stable foundation, the clamping member 200 fixes the sample, the lifting mechanism 300 adjusts the height, and finally, a tensile strength detector is applied to test the tensile strength of the fabric, thus achieving the detection of the fabric's tensile strength.

[0025] The clamping member 200 includes a first clamping plate 210, which is fixedly connected to the lifting mechanism 300; The second clamping plate 220 is slidably disposed on the first clamping plate 210, and the second clamping plate 220 moves relative to the first clamping plate 210 in a second direction (where the second direction is the direction of the second clamping plate 220 toward the first clamping plate 210). Fastener 230 is disposed between the first clamping plate 210 and the second clamping plate 220 to drive the second clamping plate 220 to move relative to the first clamping plate 210. Fastener 230 is a pneumatic cylinder or an electric sliding rod.

[0026] The first clamping plate 210 is fixedly connected to the lifting mechanism 300 to ensure the overall structure is stable and can move with the lifting mechanism 300. The second clamping plate 220 is slidably disposed on the first clamping plate 210 and can move in the second direction (i.e. towards the first clamping plate 210) to clamp fabrics of different thicknesses.

[0027] The fastener 230 is disposed between the first clamping plate 210 and the second clamping plate 220, which can generate a certain pressure when clamping the fabric, thereby controlling the movement of the second clamping plate 220 relative to the first clamping plate 210 and ensuring reliable clamping of the fabric.

[0028] The working principle is as follows: the lifting mechanism 300 drives the first clamping plate 210 to move, causing the second clamping plate 220 to move closer to or further away from the first clamping plate 210 in the second direction. The fastener 230 generates pressure during clamping, causing the second clamping plate 220 to press tightly against the first clamping plate 210, thereby clamping the fabric to test its tensile strength.

[0029] The fastener 230 includes four threaded posts 231, which are located at the four corners of the second clamping plate 220. The threaded posts 231 are disposed on the second clamping plate. A threaded hole is formed on the first clamping plate 210, and the threaded post 231 is threadedly connected to the threaded hole. A driving component 232 is disposed on the second clamping plate 220 to drive the four threaded posts 231 to rotate synchronously.

[0030] Threaded posts 231 are located at the four corners of the second clamping plate 220 for fixing and positioning; threaded holes are formed on the first clamping plate 210, cooperating with the threaded posts 231 to ensure precise alignment between the clamping plates; the driving component 232 is set on the second clamping plate 220, which can drive the four threaded posts 231 to rotate synchronously, thereby realizing the relative movement between the first clamping plate 210 and the second clamping plate 220. This reduces the uneven clamping force of the first clamping plate 210 and the second clamping plate 220 on the fabric, which leads to a large error in the tensile strength test.

[0031] The threaded connection between the threaded post 231 and the threaded hole allows the second clamping plate 220 to move towards the first clamping plate 210, thus clamping the fabric between the two plates. The working principle is as follows: the driving component 232 drives the threaded post 231 to rotate synchronously. Due to the threaded engagement between the threaded post 231 and the threaded hole, relative movement occurs between the first clamping plate 210 and the second clamping plate 220, thereby achieving precise clamping of the fabric. This method is suitable for testing the tensile properties of fabrics.

[0032] The drive unit 232 includes a chamber 233, which is formed on the second clamping plate 220, and a guide groove is formed inside the chamber 233; Toothed belt 234, the toothed belt 234 is slidably disposed in chamber 233, and a portion of the toothed belt 234 is located in guide groove; The main gear 235 is rotatably disposed in the chamber 233 and meshes with the toothed belt 234; The auxiliary gear 236 is fixedly mounted on the threaded post 231 and is located in the chamber 233. The auxiliary gear 236 is meshed with the toothed belt 234.

[0033] The drive unit 232 has a chamber 233 formed on the second clamping plate 220, and a guide groove is formed inside to guide the sliding of the toothed belt 234; the toothed belt 234 slides in the chamber 233 and is partially located in the guide groove, which plays the role of transmitting power; the main gear 235 is rotatably installed in the chamber 233 and meshes with the toothed belt 234 to transmit power through rotation. The secondary gear 236 is fixedly mounted on the threaded post 231 and located within the chamber 233, meshing with the toothed belt 234 to further transmit power. The threaded post 231 is fixedly connected to the first clamping plate 210. When the secondary gear 236 rotates, it drives the threaded post 231 to rotate. Through the cooperation between the threaded post 231 and the threaded hole, the first clamping plate 210 and the second clamping plate 220 move towards each other, ultimately allowing the first clamping plate 210 and the second clamping plate 220 to tightly clamp the fabric. This design effectively achieves precise clamping and fixation of the fabric, improving the convenience and stability of operation. At the same time, the synchronous movement of the threaded post 231 ensures that the distance between the first clamping plate 210 and the second clamping plate 220 remains moderate and stable.

[0034] A drive handle 237 is fixedly installed on the middle of the side of the main gear 235 shaft, and a hexagonal groove is opened on the side of the drive handle 237 shaft.

[0035] The drive handle 237 has a hexagonal groove on its side, allowing a rocker arm or wrench to be engaged within it for easy rotation. The main gear 235 is fixedly mounted on its shaft. Rotation of the drive handle 237 drives the main gear 235, thus transmitting power. By engaging a rocker arm or wrench within the hexagonal groove of the drive handle 237, rotation of the drive handle 237 drives the main gear 235 shaft, causing the main gear 235 to rotate synchronously, thereby achieving efficient transmission of external power.

[0036] The lifting mechanism 300 includes a cylinder 310, which is fixedly installed on the base 100 (there are two cylinders 310, located on both sides of the clamping member 200, so that the clamping mechanism can move stably); and a connecting plate 320, which is fixedly connected to the first clamping plate 210.

[0037] In the lifting mechanism 300, a cylinder 310 is fixedly mounted on the base 100 to generate a thrust perpendicular to the base 100, ensuring stable movement of the entire clamping mechanism. A connecting plate 320 is fixedly connected to the first clamping plate 210, transmitting the thrust of the cylinder 310 to the clamping member 200, ensuring accurate vertical lifting and lowering of the clamping member 200. When the piston rod of the cylinder 310 extends, the force is transmitted to the first clamping plate 210 via the connecting plate 320, causing the clamping member 200 to rise; conversely, when the piston rod retracts, the clamping member 200 descends. This design ensures that the clamping member 200 can adapt to different working requirements.

[0038] The base 100 has a guide groove 400, and the connecting plate 320 is slidably disposed within the guide groove 400. This improves the stability of the moving connecting plate 320.

[0039] An arc-shaped strip 500 is provided between the first clamping plate 210 and the second clamping plate 220. The arc-shaped strips 500 on the first clamping plate 210 and the second clamping plate 220 are staggered. The cross-section of the arc-shaped strip 500 is semi-circular. The arc-shaped strip 500 is distributed along a first direction.

[0040] The first clamping plate 210 and the second clamping plate 220 are used to clamp the fabric on both sides, respectively, while the arc-shaped strips 500 increase the clamping area and improve the clamping ability for fabrics of different thicknesses and hardnesses. The arc-shaped strips 500, staggered on the first and second clamping plates 210 and 220, not only increase the clamping surface but also ensure uniform force on the fabric during clamping, avoiding fabric damage caused by excessive localized force. By adjusting the relative positions of the first and second clamping plates 210 and 220, the arc-shaped strips 500 work together to enhance the clamping force for fabrics of different shapes and thicknesses, ensuring stability and safety during processing.
