Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and more specifically, to a fabric testing device. Background Technology

[0002] In the field of fabric tensile testing, tensile testing machines rely on clamps to fix and stretch fabric samples. However, the structural design of existing clamps is difficult to adapt to the flexibility and texture characteristics of fabrics, resulting in defects: traditional clamps mostly use smooth metal clamping surfaces, clamping the fabric only through pressure, resulting in a low coefficient of friction. When dealing with fabrics with smooth surfaces or loose textures, the sample is prone to slipping along the clamping surface during the stretching process, directly leading to distortion of key test data such as breaking strength and elongation, and poor overall performance. Therefore, this utility model proposes a fabric testing device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fabric detection device that features secure clamping and anti-detachment.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The fabric testing device involved in this utility model includes a tensile testing machine. The tensile testing machine is provided with two clamping mechanisms arranged symmetrically in the upper and lower positions. The clamping mechanism includes a clamping seat connected to the tensile testing machine. The clamping seat is provided with a fixed clamping plate that extends vertically. A movable clamping plate that also extends vertically is provided on one side of the fixed clamping plate. The movable clamping plate moves towards or away from the fixed clamping plate. The end of the fixed clamping plate facing the movable clamping plate is provided with needle punches, and the end of the movable clamping plate facing the fixed clamping plate is provided with a soft rubber pad.

[0005] The present invention is further configured such that: an adjustment block is provided on the clamping seat, an adjustment screw is threadedly connected to the adjustment block, one end of the adjustment screw is provided with a moving block, and the other end is provided with a handle for controlling rotation, and the movable clamping plate is provided on the moving block.

[0006] The present invention is further configured such that the moving direction of the adjusting screw forms a 45° angle with the horizontal plane.

[0007] The present invention is further configured such that: the clamping seat is also provided with a fixed stop plate, and the moving block is also provided with a movable stop plate that matches the fixed stop plate; When the soft rubber pad is pressed tightly against the fixed clamp, the movable stop plate abuts against the fixed stop plate.

[0008] The present invention is further configured such that the soft rubber pad is made of rubber material.

[0009] In summary, the present invention has the following beneficial effects: the fabric detection device involved in the present invention has needles on the fixed clamping surface that penetrate the fabric to form a mechanical engagement, fundamentally preventing slippage; the soft rubber pads on the movable clamping surface buffer pressure and conform to the fabric texture, avoiding edge tearing; and the combination can be adapted to fabrics of various thicknesses without complicated adjustments, and is easy to assemble and disassemble, greatly improving the accuracy of detection data and operational efficiency, meeting the needs of batch detection, with complete overall functions and strong practicality.

[0011] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0012] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0013] Example 1 See Figures 1 to 3 As shown, the fabric testing device involved in this embodiment includes a tensile testing machine (not shown). The tensile testing machine is provided with two clamping mechanisms 100 arranged symmetrically in the upper and lower positions. Each clamping mechanism 100 includes a clamping seat 1 connected to the tensile testing machine. The clamping seat 1 is provided with a fixed clamping plate 2 that extends vertically. One side of the fixed clamping plate 2 is provided with a movable clamping plate 3 that also extends vertically. The movable clamping plate 3 moves towards or away from the fixed clamping plate 2. The end of the fixed clamping plate 2 facing the movable clamping plate is provided with needle punches 4. The end of the movable clamping plate 3 facing the fixed clamping plate is provided with a soft rubber pad 5.

[0014] Furthermore, the clamping seat 1 is provided with an adjusting block 6, and an adjusting screw 7 is threadedly connected to the adjusting block 6. One end of the adjusting screw 7 is provided with a moving block 8, and the other end is provided with a handle 9 for controlling rotation. The movable clamping plate 3 is provided on the moving block 8.

[0015] Furthermore, the direction of movement of the adjusting screw 7 forms a 45° angle with the horizontal plane.

[0016] In this embodiment, one end of the strip-shaped fabric sample is placed on the upper clamp for fixation, and the other end is placed on the lower clamp for fixation. Then, a tensile testing machine is used to perform a tensile test on the clamped fabric sample.

[0017] The clamping method is as follows: First, place the end of the fabric sample between the fixed clamp 2 and the movable clamp 3. After the fabric sample is pierced by the needle 4, it is pre-positioned. Then, by holding the handle 9, the adjusting screw 7 is rotated. The adjusting screw 7 rotates relative to the adjusting block 6 and moves axially. This causes the moving block 8 to move the movable clamp 3 towards the fixed clamp 2. The needle 4 that has pierced the fabric sample then penetrates into the soft rubber pad 5, so that the soft rubber pad 5 is close to the movable clamp 3, thus completing the clamping and fixing of the fabric sample. Conversely, the clamp can be loosened.

[0018] Example 2 See Figures 1 to 3 As shown, the fabric detection device involved in this embodiment is further configured based on embodiment 1, wherein the clamping seat 1 is provided with a fixed stop plate 10, and the moving block 8 is provided with a movable stop plate 11 that matches the fixed stop plate; when the soft rubber pad 5 is tightly attached to the fixed clamping plate 2, the movable stop plate 11 abuts against the fixed stop plate 10.

[0019] In this embodiment, the fixed stop plate 10 and the movable stop plate 11 are used to limit the movement of the moving block 8, so that when the soft rubber pad 5 is tightly attached to the fixed clamping plate 2, the movable stop plate 11 abuts against the fixed stop plate 10.

[0020] The fabric testing device involved in this utility model has needles on the fixed clamping surface that penetrate the fabric to form a mechanical engagement, fundamentally preventing slippage; the soft rubber pads on the movable clamping surface buffer pressure and conform to the fabric texture to avoid edge tearing; and this combination can be adapted to fabrics of various thicknesses without complicated adjustments, and is easy to assemble and disassemble, greatly improving the accuracy of test data and operational efficiency, meeting the needs of batch testing, with complete overall functions and strong practicality.
