Description

Technical Field

[0001] This utility model relates to a tensile testing device, specifically a fabric strength tensile testing device, belonging to the field of fabric testing technology. Background Technology

[0002] After the textile fabric is processed by the fabric equipment, its tensile strength needs to be tested. The testing method is to clamp the two ends of the fabric to be tested onto the upper and lower ends of the testing machine through the clamping mechanism. The upper end of the testing machine is the power end, and the lower end of the testing machine is the fixed end. During the test, the top power end pulls the fabric upward and stretches it. The tensile strength of the fabric is obtained based on the tensile force it can withstand when stretched to plastic deformation.

[0003] Chinese Patent Application Publication No. CN218036076U discloses a tensile strength testing device for antistatic fabric production. This utility model improves the efficiency of tensile testing of antistatic fabrics, facilitates users in fixing and clamping the fabric, and makes it convenient for testers to record the test values, thereby obtaining accurate values ​​and improving the accuracy of the test.

[0004] While the above-mentioned patented solution makes it convenient for users to fix and clamp the fabric, the distance between the two clamps of the testing device in the above-mentioned patent is fixed, and the size of the sample to be tested is fixed. When the sample size is too long, the two ends of the fabric are prone to folding when clamped, and pressing with the testing head will cause the stress points of the fabric to be more concentrated, which will have a certain impact on the test data.

[0005] Therefore, a fabric strength tensile testing device is proposed here. Utility Model Content

[0006] This invention proposes a fabric strength tensile testing device that uses a second anti-slip plate and a first anti-slip plate to clamp the fabric, increasing the friction of the fabric when it is fixed, and at the same time, it can organize the excess fabric after clamping, thereby preventing the fabric from folding at both ends when clamped.

[0007] This utility model is achieved through the following technical solution: a fabric strength tensile testing device, including a protective frame, a connecting frame fixed inside the protective frame, a positioning frame fixed on one side of the connecting frame, a movable frame slidably connected inside the connecting frame, two upright plates fixed on the top surfaces of both the positioning frame and the movable frame, a rotating rod installed between the two upright plates, a connecting wheel fixedly sleeved around the rotating rod, a clamping assembly for fixing the fabric provided on one side of the connecting wheel, the clamping assembly including a support frame fixed to one side of the connecting wheel, a first anti-slip plate fixed on one side of the support frame, a second threaded rod threaded inside the support frame, a connecting collar rotatably sleeved at one end of the second threaded rod, a transmission block fixed on one side of the connecting collar, and a clamping plate sliding on one side of the support frame fixed on the top surface of the transmission block, a second anti-slip plate fixed on one side of the clamping plate.

[0008] Furthermore, the support frame has a movable groove inside, and the transmission block is slidably connected inside the movable groove.

[0009] Furthermore, a set of grooves is provided on one side of the first anti-slip plate, and a set of protrusions matching the grooves are fixed on the side of the second anti-slip plate close to the first anti-slip plate.

[0011] Furthermore, the rotating rod located above the positioning frame is fixedly sleeved between the two upright plates, and the rotating rod located above the movable frame is rotatably sleeved between the two upright plates.

[0012] Furthermore, a set of scale rods are evenly fixed on one side of the protective frame near the connecting frame, and an indicator rod matching the scale rods is provided on the top surface of the movable frame.

[0013] A positioning wheel is fixedly sleeved around the rotating rod above the movable frame. A locking assembly for fixing the position of the positioning wheel is provided on one side of the upright plate. The locking assembly includes a limiting frame fixed to one side of the upright plate. A top rod is slidably sleeved inside the limiting frame. A locking block is fixed to the top of the top rod.

[0019] The technical solutions of the embodiments of this application 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 application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0020] Please see Figures 1-4The present invention proposes the following implementation scheme: a fabric strength tensile testing device, including a protective frame 1, a connecting frame 2 fixed inside the protective frame 1, a positioning frame 3 fixed on one side of the connecting frame 2, a movable frame 4 slidably connected inside the connecting frame 2, two upright plates 5 fixed on the top surfaces of the positioning frame 3 and the movable frame 4, a rotating rod 6 installed between the two upright plates 5, a connecting wheel 7 fixedly sleeved around the outer periphery of the rotating rod 6, a clamping assembly 8 for fixing the fabric on one side of the connecting wheel 7, the clamping assembly 8 including a support frame 81 fixed on one side of the connecting wheel 7, a first anti-slip plate 82 fixed on one side of the support frame 81, a second threaded rod 85 threaded inside the support frame 81, a connecting collar 86 rotatably sleeved at one end of the second threaded rod 85, a transmission block 87 fixed on one side of the connecting collar 86, and a clamping plate 83 slidably sliding on one side of the support frame 81 fixed on the top surface of the transmission block 87, and a second anti-slip plate 84 fixed on one side of the clamping plate 83.

[0021] Please refer to this carefully. Figure 3 The support frame 81 has a movable groove 88 inside, and the transmission block 87 is slidably connected inside the movable groove 88.

[0022] A set of grooves is provided on one side of the first anti-slip plate 82, and a set of protrusions matching the grooves are fixed on the side of the second anti-slip plate 84 near the first anti-slip plate 82.

[0023] In the above scheme, rotating the second threaded rod 85 causes the transmission block 87 to drive the clamping plate 83 to slide on one side of the support frame 81, and drives the second anti-slip plate 84 to approach the first anti-slip plate 82, which can clamp the fabric.

[0024] Please refer to this carefully. Figure 2 A motor 21 is fixed to one side of the connecting frame 2. A first threaded rod 22 is fixed to the output end of the motor 21. The first threaded rod 22 is threadedly sleeved inside the movable frame 4 and is rotatably connected inside the connecting frame 2.

[0025] In the above scheme, the starting motor 21 drives the first threaded rod 22 to rotate inside the connecting frame 2, and at the same time drives the moving frame 4 to move together, which can perform stretch testing on the clamped fabric, and observe the stretch testing range of the fabric through the scale rod 11.

[0026] Please refer to this carefully. Figure 1 and Figure 2 The rotating rod 6 located above the positioning frame 3 is fixedly sleeved between the two upright plates 5, and the rotating rod 6 located above the moving frame 4 is rotatably sleeved between the two upright plates 5.

[0027] Please refer to this carefully. Figure 1A set of scale rods 11 are evenly fixed on one side of the protective frame 1 near the connecting frame 2, and an indicator rod matching the scale rods 11 is provided on the top surface of the movable frame 4.

[0028] Please refer to this carefully. Figure 4 A positioning wheel 61 is fixedly sleeved around the rotating rod 6 above the movable frame 4. A locking assembly 9 for fixing the position of the positioning wheel 61 is provided on one side of the upright plate 5. The locking assembly 9 includes a limiting frame 91 fixed on one side of the upright plate 5. A top rod 92 is slidably sleeved inside the limiting frame 91. A locking block 93 is fixed at the top of the top rod 92. A groove matching the protrusion on the surface of the positioning wheel 61 is opened on the top surface of the locking block 93. A compression spring 95 is fixed on the bottom surface of the top rod 92. A support plate 96 is fixed at the bottom end of the compression spring 95 and the support plate 96 is fixed on one side of the upright plate 5.

[0029] A lever 94 is fixed to one side of the top rod 92, and the lever 94 is located below the limit frame 91.

[0030] In the above scheme, rotating the positioning wheel 61 causes the excess fabric to be rolled up to the surface of the connecting wheel 7. Then, the compression spring 95 pushes the top rod 92 upward and makes the locking block 93 contact the surface of the positioning wheel 61, which can fix the position of the rotating rod 6 and the connecting wheel 7 and can sort out the excess fabric.

[0031] In use, the following steps are taken: Place both ends of the fabric on one side of each of the two connecting wheels 7. Then, rotate the second threaded rod 85 to cause the transmission block 87 to slide the clamping plate 83 on one side of the support frame 81, and move the second anti-slip plate 84 closer to the first anti-slip plate 82. This clamps the fabric, increasing friction during fixation and preventing slippage during stretching. Press down the lever 94 to make the top rod 92 slide inside the limiting frame 91, and move the locking block 93 away from the positioning wheel 61. Then, rotate the positioning wheel 61 to roll up excess fabric to the surface of the connecting wheel 7. Use the compression spring 95 to push the top rod 92 upwards, making the locking block 93 contact the surface of the positioning wheel 61. This fixes the position of the rotating rod 6 and the connecting wheel 7, tidying up excess fabric and preventing folding at both ends during clamping, thus improving the accuracy of fabric testing data. Then, start the motor 21 to rotate the first threaded rod 22 inside the connecting frame 2, simultaneously moving the moving frame 4. This allows for stretch testing of the clamped fabric, and the stretch testing range can be observed using the scale rod 11.
