Description

Technical Field

[0001] This utility model relates to the field of cotton testing technology, and in particular to a device for testing the quality of cotton fibers. Background Technology

[0002] Cotton fiber is a natural fiber extracted from cotton and is one of the longest-used fibers by humankind. It is primarily composed of cellulose, a major component of plant cell walls. These fibers typically have a long, filamentous structure, possessing softness, breathability, and excellent moisture absorption. Due to these properties, cotton fibers are widely used in textile manufacturing, such as cotton fabrics and yarns. They can be made into various garments, bedding, home textiles, and textiles for industrial use. Cotton fibers can also be processed using different methods, such as compression, bleaching, dyeing, and finishing, to meet the needs of various applications.

[0003] For example, Chinese utility model patent (CN220854450U) discloses a cotton fiber quality testing device, which states: "It enables effective tensile testing of cotton fibers, determining whether the fiber strength and extensibility meet specific quality standards and requirements, and can record the testing process, thereby improving testing efficiency and capacity." However, it also states: "However, this method cannot perform tensile testing on cotton fibers. Tensile strength is one of the important indicators for evaluating cotton fiber strength. The inability of the testing device to perform tensile testing will prevent accurate assessment of the strength characteristics of cotton fibers. This will limit the accurate assessment of cotton fiber quality by fiber suppliers and textile manufacturers, as well as the selection of suitable fibers for specific applications."

[0004] In summary, the existing technology uses two bidirectional lead screws to drive two sets of arc-shaped clamps to fix cotton fibers. However, this method has the following technical problems: In actual use, it has been found that multiple rotations of the handle are required to fix one side of the cotton fiber when clamping it. This method is too time-consuming and reduces the efficiency of cotton fiber strength testing. Therefore, this application proposes a cotton fiber quality testing device to solve the technical problems mentioned in the above patent and provide a new technical solution. Utility Model Content

Then, when gripping cotton fibers of similar size, simply place one side of the cotton fiber between the first and second grippers, and then push the L-shaped plate to move the second gripper towards the position of the first gripper, thereby restricting the cotton fiber and completing the gripping process. After testing, simply rotate the rotating rod to release the restriction of the restricting gripper on the restricting plate, and then pull the L-shaped plate to remove the cotton fiber. This process is simple and quick, thus improving the efficiency of cotton fiber testing and enhancing the practicality of the device.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0029] As described in the background art, however, it was found in the actual use of the device that when clamping cotton fibers, it is necessary to rotate the handle multiple times to fix one side of the cotton fiber. This method is too time-consuming and reduces the efficiency of cotton fiber strength testing.

[0030] To solve this technical problem, this utility model provides a cotton fiber quality testing device, which is applied to the testing of cotton fiber tensile strength.

[0031] For details, please refer to Figures 1-3 The cotton fiber quality testing device specifically includes:

[0032] The device base 1 has a support frame 2 fixedly connected to its top. The device base 1 is equipped with a tensioning mechanism 6, which has two clamping mechanisms 5. A hydraulic rod 3 is fixedly installed at the bottom of the support frame 2, and a detector 4 is fixedly installed at the bottom of the hydraulic rod 3.

[0033] The clamping mechanism 5 includes a sliding shell 7, a fixed rod 9, a moving block 10, an adjusting component, a pushing component, and a limiting component. The fixed rod 9 is fixedly connected to the inner wall of the sliding shell 7, and the moving block 10 is slidably connected to the inner wall of the sliding shell 7. The moving block 10 is slidably connected to the outer wall of the fixed rod 9.

[0034] The cotton fiber quality testing device provided by this utility model allows the position of the first gripper 11 to be adjusted to a suitable position by rotating the adjusting screw 8. Then, when clamping cotton fibers of similar size, simply place one side of the cotton fiber between the first gripper 11 and the second gripper 13, and then push the L-shaped plate 15 to move the second gripper 13 towards the position of the first gripper 11, thereby restricting the cotton fiber and completing the clamping of the cotton fiber. After the test is completed, simply rotate the rotating rod 17 to release the restriction of the restricting claw 18 on the restricting plate 14, and then pull the L-shaped plate 15 to remove the cotton fiber. This process is simple and quick to operate, thereby improving the efficiency of cotton fiber testing and enhancing the practicality of the device.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 2-5 A cotton fiber quality testing device, comprising:

[0038] The adjustment assembly includes an adjustment screw 8, which is rotatably connected to the inner wall of the sliding shell 7. The moving block 10 is threadedly connected to the outer wall of the adjustment screw 8. The adjustment screw 8 can drive the moving block 10 to move under the restriction of the fixed rod 9, thereby adjusting the position of the first gripper 11 and thus adjusting the position of the cotton fiber fixation. The top of the moving block 10 is fixedly connected to the first gripper 11.

[0039] The pushing component includes an L-shaped plate 15, which is slidably connected to the inner wall of the sliding shell 7. A limiting plate 14 is fixedly connected to the outer wall of the L-shaped plate 15. The limiting plate 14 is slidably connected to the inner wall of the sliding shell 7. An I-shaped block 12 is fixedly connected to the top of the L-shaped plate 15. The bottom of the I-shaped block 12 is fixedly connected to the top of the limiting plate 14. A second gripper 13 is fixedly connected to the top of the I-shaped block 12. The I-shaped block 12 connects the second gripper 13 to the limiting plate 14 and the L-shaped plate 15, so that pushing the L-shaped plate 15 can drive the second gripper 13 to cooperate with the first gripper 11 to clamp the cotton fibers. The limiting plate 14 restricts the position of the second gripper 13.

[0040] The limiting assembly includes a fixed shell 16, with the fixed shell 16 fixedly connected to the outer wall of the sliding shell 7. A rotating rod 17 is rotatably connected to the inner wall of the fixed shell 16. A knob for rotating the rotating rod 17 is fixedly connected to the top of the rotating rod 17. A limiting claw 18 adapted to the limiting plate 14 is fixedly connected to the outer wall of the rotating rod 17. A torsion spring 19 is sleeved on the outer wall of the rotating rod 17 inside the fixed shell 16. The torsion spring 19 allows the limiting claw 18 to remain tightly attached to the outside of the limiting plate 14 when no external force is applied to the rotating rod 17. The upper and lower ends of the torsion spring 19 are fixedly connected to the inner wall of the fixed shell 16 and the top of the limiting claw 18, respectively.

[0041] With the above structural design, rotating the adjusting screw 8 can drive the moving block 10 to slide along the fixed rod 9 under the restriction of the sliding shell 7 and the fixed rod 9, thereby adjusting the position of the first gripper 11 to a suitable position. Then, when clamping cotton fibers of similar size, simply place one side of the cotton fiber between the first gripper 11 and the second gripper 13, and then push the L-shaped plate 15 so that the L-shaped plate 15 and the limiting plate 14 slide on the inner wall of the sliding shell 7, thereby driving the I-shaped block 12 to approach the moving block 10, and then fix the cotton fiber under the restriction of the second gripper 13 and the first gripper 11, thus completing the clamping of the cotton fiber. After the test is completed, simply rotate the rotating rod 17 to drive the limiting claw 18 to move accordingly. During this process, the torsion spring 19 deforms accordingly. Then, pull the L-shaped plate 15 to remove the cotton fiber. Release the rotating rod 17, and under the action of the elastic force of the torsion spring 19, the limiting claw 18 will once again be tightly attached to the outer wall of the limiting plate 14.

[0042] Example 2:

[0043] The cotton fiber quality testing device provided in Example 1 has been further optimized, specifically, as follows: Figures 2-3 As shown, the stretching mechanism 6 includes a drive motor 20. The drive motor 20 is fixedly installed on the outer wall of the device base 1. The output end of the drive motor 20 is fixedly connected to a bidirectional threaded rod 21. The bidirectional threaded rod 21 is rotatably connected to the inner wall of the device base 1. The bidirectional threaded rod 21 allows the two sliding shells 7 to simultaneously approach or move away from each other, thereby performing tensile strength testing on the cotton fibers.

[0044] The stretching mechanism 6 also includes threaded blocks 22. The outer wall of the bidirectional threaded rod 21 and the two sides of the middle section are respectively threaded with threaded blocks 22. The bottom of the two threaded blocks 22 are respectively fixedly connected with T-shaped blocks 23. The T-shaped blocks 23 are slidably connected to the inner wall of the device base 1. The T-shaped blocks 23 slide inside the device base 1 to restrict the threaded blocks 22, reduce the shaking generated during the movement of the threaded blocks 22, thereby improving the stability of the device and improving the accuracy of cotton fiber detection. The tops of the two threaded blocks 22 are respectively fixedly connected to the bottom of the sliding shell 7.

[0045] With the above structural design, after the cotton fibers are clamped, the drive motor 20 is started, which drives the bidirectional threaded rod 21 to rotate. This causes the two threaded blocks 22 to move away from each other under the constraint of the T-shaped block 23 and the device base 1, so that the cotton fibers are gradually stretched. At this time, the detector 4 detects and records the stretching of the cotton fibers, and then detects the tensile strength of the cotton fibers.

[0046] In this device, the principle for detecting the tensile strength of cotton fibers is essentially the same as that of the prior art mentioned in the background section.
