[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) This scheme is equipped with a suspension component. The two upper clamping parts can clamp the two ends of the fabric, so that the fabric forms a U-shaped natural suspension. The drive mechanism drives the crossbeam to descend, so that the naturally suspended fabric enters the box and is immersed in the sample liquid in the box, ensuring that the fabric and the sample liquid are in uniform contact. After soaking, the liquid squeezing component squeezes out some of the water in the fabric, and then the tensile test is performed. Under relatively controllable and repeatable conditions, the process of the fabric being completely soaked by liquid (such as sweat, rainwater, chemical reagents) in real use and the complex environment in which the fabric is in actual use are simulated, so as to truly simulate the mechanical properties of the fabric after being subjected to liquid in actual use and obtain test data that are closer to the real environment.

[0021] (2) This scheme is equipped with a flattening component. When the squeezing component squeezes the fabric to remove water, the motor can drive the seat one to move in the movable groove two. The gear key in the movable groove two can drive the two gears in the seat one to rotate, thereby causing the upper clamping part one to rotate. At the same time, the drive part can drive the upper clamping part two to rotate, which can change the upper clamping part one and the upper clamping part two from a vertical state to a horizontal state. This can flatten the suspended U-shaped fabric, maintain the fabric in a natural straight state while providing relatively small tension, so that the fabric can enter the pressing point of the two pressure rollers in a relatively flat state. Converting the U-shaped line into a straight line before squeezing can reduce the formation of creases and ensure the integrity of the fabric structure.

[0022] (3) This scheme sets up fan one, fan two and light group. By setting up two fans, the gas inside the enclosure can be convected, which can accelerate the gas flow inside the enclosure and simulate the real use environment in which the fabric is always in the air flow. The convective environment created makes the test conditions closer to reality and can detect the mechanical performance of the fabric under ventilation conditions. At the same time, the light group can simulate solar radiation and carry out light aging test. By irradiating the fabric with the light group, the attenuation law of its tensile properties under continuous light can be tested. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 9A tensile testing device for polyester elastic knitted fabric includes a base 2 and a barrier 1 fixed to the upper end of the base 2.

[0036] The base 2 is connected to a lower clamping part 22, and a box 7 is also snapped onto the base 2; the base 2 is also connected to a drive mechanism 5, and a crossbeam 6 is fixed to the moving end of the drive mechanism 5, and a suspension assembly 8 is connected to the lower end of the crossbeam 6.

[0037] The suspension assembly 8 includes a second crossbeam 81 connected to the lower end of the first crossbeam 6, a first movable groove 811 opened inside the second crossbeam 81, a movable plate 82 slidably connected in the first movable groove 811, a first displacement assembly connected inside the second crossbeam 81 and driving the movable plate 82 to translate, a first seat 83 connected to the lower end of the second crossbeam 81, a movable seat 84 connected inside the first seat 83, a first upper clamping part 85 fixed to the lower end of the movable seat 84, and a second upper clamping part 86 connected to the lower end of the second crossbeam 81.

[0038] The lower end of the movable plate 82 is also connected to a liquid rolling assembly 9, and the liquid rolling assembly 9 includes a frame 93 that slides on the lower end of the movable plate 82, two sets of liquid rolling parts that are movably connected to the inner wall of the frame 93, and a second displacement assembly that is connected to the side of the movable plate 82 and drives the frame 93 to move.

[0039] The lower end of the first crossbeam 6 is provided with a clearance groove 61 to accommodate the second crossbeam 81. The first displacement component includes a lead screw 812 screwed inside the movable plate 82, and both ends of the lead screw 812 are rotatably connected to the inner wall of the movable groove 811. A motor 813 is fixedly connected to one side of the second crossbeam 81, and the output shaft of the motor 813 passes through the second crossbeam 81 and is fixedly connected to one end of the lead screw 812.

[0040] The rolling section includes a pressure roller 97 and two sliders 94 rotatably connected to both ends of the pressure roller 97. Both sliders 94 are slidably connected to the inner wall of the frame 93. A second lead screw 95 is also rotatably connected inside the frame 93. The second lead screw 95 is screwed into the two sliders 94 on the same side. A third motor 96 is fixedly connected to the bottom of the frame 93. The output shaft of the third motor 96 passes through the frame 93 and is fixedly connected to one end of the second lead screw 95.

[0041] The second displacement component includes a lead screw 91 rotatably connected to one side of the movable plate 82 and a motor 92 fixedly connected to one side of the movable plate 82. The output shaft of the motor 92 is fixedly connected to one end of the lead screw 91, and the lead screw 91 is screwed inside the frame 93.

[0042] By adopting the above technical solution, one end of the fabric to be stretched is clamped by the upper clamping part 85, and the other end of the fabric passes between the two pressure rollers 97 and is clamped by the upper clamping part 86. After the fabric is clamped, the middle of the fabric will naturally hang down due to gravity, achieving the effect of fabric suspension. Then, the motor 813 is controlled to drive the lead screw 812 to rotate. The rotation of the lead screw 812 can cause the movable plate 82 to move horizontally, so that the suspended fabric can move to the upper end of the box 7. The drive mechanism 5 is controlled to drive the crossbeam 6 to descend. The drive mechanism 5 is usually a motor + lead screw, which drives the crossbeam 6 to move up and down. The sample is subjected to tension. When the crossbeam 6 descends above the box 7, the suspended fabric enters the box 7 and is immersed in the test sample solution inside the box 7. The test sample solution can be sweat, rainwater, chemical reagents, etc. After the fabric is immersed in the box 7, the drive mechanism 5 drives the crossbeam 6 to rise, and then controls the motor 3 96 to work. The motor 3 96 drives the lead screw 2 95 to rotate. The rotation of the lead screw 2 95 causes the two sliders 94 on the same side to move towards each other. The movement of the two sliders 94 drives the two pressure rollers 97 to move towards each other, and the distance between the two pressure rollers 97 becomes smaller, thus squeezing the fabric through the two pressure rollers 97. At the same time, the motor 2 92 is controlled to work, driving the lead screw 4 91 to rotate. The screw 4 (91) rotates, driving the frame 93 to move horizontally below the movable plate 82. This horizontal movement of the frame 93 causes the two pressure rollers 97 to move horizontally, squeezing the portion of the fabric that is suspended and immersed in liquid, thus squeezing out some of the water and reducing the liquid content of the fabric. After squeezing, the two pressure rollers 97 are reset, and the movable plate 82 is moved back to its original position above the lower clamping part 22. Then, the upper clamping part 2 (86) releases its grip on one end of the fabric, and the lower clamping part 22 clamps that end of the fabric again. The drive mechanism 5 drives the crossbeam 6 to rise, and the upper clamping part 85 pulls the fabric under tension. The tensile strength is detected by a force sensor inside the upper clamping part 85, thereby achieving... The tensile properties of the fabric after wetting are tested. It should be noted that most current tensile testing equipment integrates the upper clamp and force sensor, and the tensile force is accurately and in real time collected during the process of the upper clamp pulling the workpiece under tension. At the same time, the principle of tensile testing of fabric is also a mature existing technology, which will not be elaborated here. In this way, under relatively controllable and repeatable conditions, the process of the fabric being completely soaked by liquids (such as sweat, rainwater, chemical reagents) in real use and the complex environment in which the fabric is in actual application are simulated, so as to realistically simulate the mechanical properties of the fabric after being subjected to liquid in actual use and obtain test data that is closer to the real environment.

[0043] like Figure 4 , Figures 6-8As shown, two side plates 87 are symmetrically fixed to the lower end of the movable plate 82. An upper clamping part 86 is rotatably connected between the two side plates 87. A rotation drive part 88 is fixed to one side of one of the side plates 87, and the output shaft of the rotation drive part 88 is connected to the upper clamping part 86.

[0044] The movable plate 82 is also connected to a flattening assembly 10, which includes a movable groove 101 at the lower end of the movable plate 82 and a lead screw 103 rotatably connected to the inner wall of the movable groove 101. A motor 102 is also fixedly connected to one side of the movable plate 82, and the output shaft of the motor 102 is fixedly connected to one end of the lead screw 103. The seat 83 is slidably connected in the movable groove 101, and the lead screw 103 is screwed into the seat 83.

[0045] The movable seat 84 is rotatably connected to the inside of the seat body 83. The inner wall of the movable groove 101 is provided with a key 104. The inside of the seat body 83 is provided with a groove 831 to avoid the key 104. The inside of the seat body 83 is rotatably connected with a gear 105 and a gear 106 that meshes with the gear 105. The gear 105 extends into the groove 831 and meshes with the key 104. The gear 106 is fixedly connected to one side of the movable seat 84.

[0046] By adopting the above technical solution, after the suspended part of the fabric is soaked in the box 7, the drive mechanism 5 drives the crossbeam 6 to rise. Before the liquid squeezing assembly 9 squeezes the fabric, the control motor 102 drives the lead screw 103 to rotate. The rotation of the lead screw 103 can drive the seat 83 to move in the movable groove 101. When the seat 83 moves, the gear key 104 can drive the gear 105 and gear 106 to rotate. The rotation of gear 106 can drive the movable seat 84 to rotate. The rotation of the movable seat 84 drives the upper clamping part 85 to rotate, so that the upper... The clamping part 85 rotates during translation, and the rotation drive part 88 drives the upper clamping part 86 to rotate, so that the upper clamping parts 85 and 86 change from a vertical state to a horizontal state. When the two upper clamping parts become horizontal, the naturally hanging fabric can be converted from a U-shaped line to a straight line, so that the hanging U-shaped fabric is flattened. While maintaining the natural straightness of the fabric, it provides relatively small tension, so that the fabric can enter the pressing point of the two pressure rollers 97 in a relatively flat state and then be squeezed. This can reduce the formation of creases and ensure the integrity of the fabric structure.

[0047] like Figure 1 , Figure 2 , Figure 9As shown, a side door 3 is rotatably connected to one side of the enclosure 1, and an air outlet 4 is provided inside the side door 3. Two upright plates 12 are fixedly connected to the upper end of the base 2 and one side of the side door 3, respectively. Fan 13 and Fan 2 15 are fixedly connected inside the two upright plates 12, respectively. A light group 14 is also fixedly connected to one side of one of the upright plates 12. An air inlet 17 is provided inside the enclosure 1.

[0048] A filter screen 16 is fixedly attached to the inner wall of the air inlet 17.

[0049] By adopting the above technical solution, before or during the tensile test of the fabric, the operation of fan 13 can draw external air into the enclosure 1 from the air inlet 17, and the operation of fan 2 15 can exhaust the air inside the enclosure 1 from the air outlet 4, so that the gas inside the enclosure 1 forms convection, accelerates the gas flow inside the enclosure 1, and simulates the real use environment in which the fabric is always in airflow. The created convection environment makes the test conditions closer to reality and can detect the mechanical performance of the fabric under ventilation conditions. At the same time, the lamp group 14 can be a xenon lamp, which can better simulate the full solar spectrum and simulate solar irradiation to conduct photoaging tests. By irradiating the fabric with lamp group 14, the decay law of its tensile properties under continuous light can be tested.

[0050] like Figure 2 and Figure 3 As shown, a turntable 21 is fixedly connected to the lower end of the lower clamping part 22, and the lower end of the turntable 21 is rotatably connected to the upper end of the base 2. A rotating part 23 is fixedly connected inside the base 2, and the rotating shaft of the rotating part 23 is fixedly connected to the lower end of the turntable 21. A rotating drive part 21 is fixedly connected to the upper end of the crossbeam 1 6, and the output shaft of the rotating drive part 2 11 passes through the crossbeam 1 6 and is fixedly connected to the upper end of the crossbeam 2 81.

[0051] By adopting the above technical solution, before performing tensile testing, the rotation drive unit 21 can be controlled to work, driving the crossbeam 21 to rotate. The rotation of the crossbeam 21 can drive the upper clamping unit 15 to rotate, and at the same time, the rotating unit 23 can work to drive the lower clamping unit 22 to rotate. The synchronous rotation of the upper clamping unit 15 and the lower clamping unit 22 can drive the fabric to rotate. By making the fabric rotate, the fabric can be more evenly illuminated by the lamp group 14, simulating a more uniform lighting effect.

[0052] Instructions for use: The upper clamping part 85 clamps one end of the fabric to be stretched, while the other end of the fabric passes between the two pressure rollers 97 and is clamped by the upper clamping part 86. After clamping, the fabric hangs down naturally due to gravity, achieving a hanging effect. The hanging fabric moves to the upper part of the box 7, and the drive mechanism 5 lowers the crossbeam 6. The hanging fabric enters the box 7 and is immersed in the test sample solution inside. After the fabric is immersed in the box 7, the drive mechanism 5 raises the crossbeam 6, and the leveling assembly 10 is activated. The upper clamping part 1 85 and the upper clamping part 2 86 are changed from a vertical state to a horizontal state, transforming the naturally hanging fabric from a U-shaped line into a straight line. Then, the moisture in the fabric is squeezed out by the liquid squeezing assembly 9, reducing the liquid content of the fabric. After squeezing, the two pressure rollers 97 are reset and the movable plate 82 is moved and reset to above the lower clamping part 22. Then, the upper clamping part 2 86 is released from clamping one end of the fabric, and the lower clamping part 22 clamps one end of the fabric. The drive mechanism 5 drives the crossbeam 1 6 to rise, and the upper clamping part 1 85 pulls the fabric under tension. The tensile strength is detected by the force sensor inside the upper clamping part 1 85.

[0053] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
