[0002] Fabric tensile test is one of important indexes of measuring fabric quality, has important significance to detect the strength and durability of fabric, and fabric tensile strength refers to the maximum tensile force that fabric can bear under the action of force.

[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0020] Please refer to Figures 1-4The utility model provides a technical scheme: a fabric tensile test mechanism, including base 1, the top of base 1 is fixedly arranged with mounting bracket 2, the inner wall of the both sides stand of mounting bracket 2 is fixedly arranged with swivel lever 3, and one end of two swivel levers 3 is commonly inserted with rotary drum 4, and the both ends of rotary drum 4 are rotatably connected with threaded lead screw 5 and slide bar 6, and the top and bottom of threaded lead screw 5 and slide bar 6 are commonly connected with arc pressing plate 7, and the top of threaded lead screw 5 is fixedly arranged with hand screw knob 10, and the bottom of threaded lead screw 5 and the top and bottom of slide bar 6 are commonly inserted with limit block 11.

[0021] When the fabric tensile test is carried out, first, one end of the fabric is wound on the surface of the rotary drum 4, and the handle fixedly arranged on one side of the swivel lever 3 is used to drive the swivel lever 3 and the rotary drum 4 to rotate, so that the fabric is wound on the rotary drum 4, and after several turns of the fabric are wound, the threaded lead screw 5 and the slide bar 6 are inserted into the both ends of the rotary drum 4, then the arc pressing plate 7 is installed on the top and bottom of the threaded lead screw 5 and the slide bar 6, and then the limit block 11 is inserted into the top and bottom of the slide bar 6 and the bottom of the threaded lead screw 5 to limit, and then the hand screw knob 10 is rotated to make the arc pressing plate 7 abut against the surface of the fabric, so that the fabric is pressed tightly, thereby preventing the fabric from falling off the surface of the rotary drum 4 during the tensile test.

[0022] It should be noted that the arc pressing plate 7 is used to press the fabric and make the wound fabric tightly pressed, thereby increasing the friction between the fabrics, and the friction cooperates with the pressing of the arc pressing plate 7 on the fabric to prevent the fabric from falling off the surface of the rotary drum 4 during the tensile test.

[0023] It should be noted that the hand screw knob 10 and the limit block 11 can be connected to the upper and lower ends of the threaded lead screw 5 and the slide bar 6 through threads, and after the hand screw knob 10 is completely screwed on the top of the threaded lead screw 5, the hand screw knob 10 will drive the threaded lead screw 5 to rotate.

[0024] Referring to Figures 1-4 Each end surface of the arc pressing plate 7 is fixedly arranged with a snap ring 9, and the double-hook springs 8 are clamped between the upper and lower snap rings 9.

[0025] During implementation, the double-hook springs 8 are then used to tighten the two sides of the arc pressing plate 7, so that the two ends of the arc pressing plate 7 can also tightly press the fabric, so that the inner surface of the entire arc pressing plate 7 can abut against the surface of the fabric, thereby achieving the pressing of the fabric.

[0026] It should be noted that the upper and lower ends of the double-hook spring 8 are provided with hooks, which are connected with the clasp 9, so as to clamp the upper and lower arc-shaped pressing plates 7, and the two ends of the arc-shaped pressing plate 7 also abut against the surface of the fabric. Moreover, the length of the rotating drum 4 is greater than the width of the fabric, and the double-hook spring 8 does not contact the fabric, so as not to prevent the tensile test of the fabric.

[0027] Referring to Figures 1-4 The inner part of the rotating rod 3 is provided with a sliding groove 12, and the inner wall surface of the sliding groove 12 is fixedly provided with a compression spring 13.

[0028] In the specific implementation, when the rotating drum 4 is installed between the two rotating rods 3, the compression spring 13 arranged in the rotating rod 3 is in a compressed state, and different lengths of the rotating drum 4 can be used for different widths of the fabric, and the rotating drum 4 is clamped between the two rotating rods 3, so as to wind the fabric.

[0029] It should be noted that the tensile test of the fabric is to evaluate the quality, durability and service life of the fabric, and the tensile strength is one of the important indicators of the quality of the fabric. Through the tensile test, the maximum force that the fabric can withstand when stretched can be measured, so as to judge whether the quality of the fabric meets the standard. This helps to ensure that consumers purchase high-quality textiles, and the tensile test can reflect the durability and service life of the fabric during use. If the tensile strength is insufficient when the fabric is stretched by external force, it is easy to break or damage. Therefore, through the tensile test, the performance of the fabric in actual use can be predicted, and important information about the durability of the fabric can be provided to consumers. For textile manufacturers, the detection of the tensile strength of the fabric can also provide information about their production process and materials. By analyzing the test results, manufacturers can understand the weak links in the production process, and then improve the production process and improve product quality.

[0030] Working principle: when the tensile test of the fabric is performed, first, one end of the fabric is wound around the surface of the rotating drum 4, and the handle fixedly arranged on one side of the rotating rod 3 is used to drive the rotating rod 3 and the rotating drum 4 to rotate, so that the fabric is wound around the rotating drum 4. After several turns of the fabric are wound, the threaded lead screw 5 and the sliding rod 6 are inserted into the two ends of the rotating drum 4, then the arc-shaped pressing plates 7 are respectively installed on the top and bottom of the threaded lead screw 5 and the sliding rod 6, then the limiting blocks 11 are inserted into the top and bottom of the sliding rod 6 and the bottom of the threaded lead screw 5 for limiting, then the hand screw knob 10 is rotated, so that the arc-shaped pressing plates 7 abut against the surface of the fabric, thereby tightly pressing the fabric, so as to prevent the fabric from falling off the surface of the rotating drum 4 during the tensile test of the fabric.

[0031] Then the two edges of the arc-shaped pressing plate 7 are pulled tight by the double-hook spring 8, so that the two ends of the arc-shaped pressing plate 7 can also tightly press the fabric, so that the inner side surface of the whole arc-shaped pressing plate 7 can be in contact with the surface of the fabric, thereby realizing the pressing of the fabric.

[0032] When the rotating drum 4 is installed between the two rotating rods 3, the compression spring 13 arranged inside the rotating rod 3 is in a compressed state, and for different widths of the fabric, different lengths of the rotating drum 4 can be replaced, and the rotating drum 4 is clamped between the two rotating rods 3, so as to wind the fabric.

[0033] The above is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the preferred embodiment of the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and the equivalent embodiments of the equivalent changes can be obtained. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the scope of the present application.
