Description

Technical Field

[0001] The utility model relates to the technical field of fabric elasticity testing, in particular to a fabric elasticity testing machine. Background Technique

[0002] A fabric elasticity testing machine is a kind of instrument and equipment specially used for measuring the elastic properties of fabrics. It applies specific forces or deformations to the fabrics and then measures various parameters of the fabrics during the process of being stressed or deformed, such as elongation, restoring force, elastic modulus, etc., to evaluate the elastic degree and recovery ability of the fabrics. Fabric elasticity testing machines are widely used in the fields of quality inspection and product research and development in the textile industry. Through accurate measurement of the fabric elasticity, it can provide important basis for optimizing the production process and controlling the product quality of fabrics to ensure that the produced fabrics have good elastic properties and meet different usage requirements. Currently, when fabrics are being tested, common testing machines may not be able to provide enough friction for some fabrics with relatively smooth surfaces, resulting in easy sliding of the fabrics during the testing process, affecting the reliability of the test data. Moreover, the traditional manual method of removing and installing weights takes a long time for installation and removal, with cumbersome operations and reduced testing efficiency. Content of the Utility Model

[0011] (III) Beneficial effects

[0012] 1. Place the upper end of the fabric between the clamp block and the connecting block, rotate the screw in the opposite direction to push the clamp block and the connecting block to engage, and fix the fabric. A group of teeth are arranged on the surface of the clamp block. When the fabric is subjected to elasticity test, it will be subjected to downward pulling force. The existence of the teeth can increase the friction with the surface of the fabric, effectively preventing the fabric from slipping during the test, ensuring the accuracy of the test results, and the teeth can make the pressure of the connecting block and the clamp block on the fabric more evenly distributed. When clamping the fabric, the teeth can contact the upper end of the fabric evenly, dispersing the pressure to multiple points, and avoiding damage to the fabric due to excessive local pressure.

[0013] 2. Start the cylinder and its output shaft will drive the fixed block to move upward. The block will drive the fixed support block to move during the movement. At this time, the support block carries the weight during the upward movement to make it out of the suspended state, so as to observe and calculate the elastic recovery rate of the sample. When it is necessary to test again, the support block is driven by the cylinder to reset. When conducting a series of elastic tests under different load conditions, there is no need to operate manually one by one. The state of the weight can be quickly adjusted by controlling the action of the cylinder, thereby improving the consistency and efficiency of the test. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the general idea of the embodiments of the present application is as follows:

[0023] Aiming at the problems existing in the prior art, the present utility model provides a fabric elasticity testing machine, including a fixed frame 2, a connecting rod 4 and a group of frames 1. The upper ends of a group of frames 1 are fixedly connected with connecting blocks 10, the front surfaces of a group of connecting blocks 10 are fixedly connected with fixed blocks 5, a group of frames 1 are respectively fixedly connected with the fixed frame 2 and the connecting rod 4, the front surface of the connecting rod 4 is fixedly connected with a group of displays 3 by screws, the left surfaces of a group of frames 1 are fixedly connected with cylinders 6, a group of clamping blocks 7 are arranged below a group of cylinders 6, the right surfaces of a group of clamping blocks 7 are fixedly connected with support blocks 8, the upper surfaces of a group of clamping blocks 7 are provided with second card slots 16, and a group of second card slots 16 are respectively fixedly connected with the output shafts of a group of cylinders 6. By rotating the screw 9, the clamping block 15 rotatably connected thereto is pushed to move backward together. The clamping block 15 is movably clamped in the fixed block 5 through two slide blocks 14 fixed thereon. The upper end of the fabric is placed between the clamping block 15 and the connecting block 10. By reversely rotating the screw 9, the clamping block 15 is pushed to be clamped with the connecting block 10 to fix the fabric. A group of teeth are arranged on the surface of the clamping block 15. When the fabric is subjected to elastic testing, it will be subjected to a downward pulling force. The existence of the teeth can increase the friction with the fabric surface, effectively preventing the fabric from slipping during the testing process and ensuring the accuracy of the test results.

[0024] A group of support blocks 8 are fixedly connected to the right surface with T-shaped blocks 17, a group of frames 1 are provided with T-shaped slots 18 on the left surface, a group of T-shaped blocks 17 are movably connected with a group of T-shaped slots 18 respectively, a group of fixed blocks 5 are threadedly sleeved with screws 9, a group of screws 9 are rotatably connected to clamping blocks 15 at the rear end, and the teeth can make the pressure of the connection block 10 and the clamping block 15 on the fabric more evenly distributed. When clamping the fabric, the teeth can evenly contact the upper end of the fabric to disperse the pressure to multiple points to avoid excessive local pressure and damage to the fabric.

[0025] Two card slots 11 are provided on the inner wall of a group of fixed blocks 5, and sliders 14 are fixedly connected on the left and right sides of a group of clamping blocks 15. A group of sliders 14 are respectively movably engaged with a group of card slots 11. A group of tooth grooves 13 are provided on the front surface of a group of connecting blocks 10, and each group of tooth grooves 13 is respectively movably engaged with each clamping block 15. During the test, the weight is hooked on the lower end of the fabric for testing. At this time, it is necessary to record the length or deformation of the sample under the force state for many times. When the cylinder 6 is started, its output shaft will drive the clamping block 7 fixed thereto to move upward. During the movement, the clamping block 7 will drive the support block 8 fixed thereto to move together. At this time, the support block 8 carries the weight during the upward movement to make it out of the suspended state, so as to observe and calculate the elastic recovery rate of the sample. When it is necessary to test again, the support block 8 is driven by the cylinder 6 to reset. When performing a series of elastic tests under different load conditions, there is no need to operate manually one by one. The state of the weight can be quickly adjusted by controlling the action of the cylinder 6, thereby improving the consistency and efficiency of the test.

[0026] Working principle:

[0027] When the testing machine is in use, the upper end of the fabric needs to be fixed first, and the clamping block 15 connected to it is pushed to move backward by rotating the screw 9. The clamping block 15 is movably clamped in the fixing block 5 through the two sliders 14 fixed thereon. The upper end of the fabric is placed between the clamping block 15 and the connecting block 10, and the screw 9 is rotated in the opposite direction to push the clamping block 15 to clamp with the connecting block 10 to fix the fabric. A group of teeth are arranged on the surface of the clamping block 15. When the fabric is subjected to elasticity test, it will be subjected to downward pulling force. The presence of the teeth can increase the friction with the fabric surface, effectively preventing the fabric from slipping during the test, ensuring the accuracy of the test results, and the teeth can make the pressure of the connecting block 10 and the clamping block 15 on the fabric fixation more evenly distributed. When clamping the fabric, the teeth can be evenly in contact with the upper end of the fabric. Touch, disperse the pressure to multiple points to avoid damage to the fabric due to excessive local pressure. During the test, the weight is hooked on the lower end of the fabric for testing. At this time, it is necessary to record the length or deformation of the sample under stress for many times. Start the cylinder 6 and its output shaft will drive the block 7 fixed with it to move upward. The block 7 will drive the support block 8 fixed with it to move during the movement. At this time, the support block 8 carries the weight during the upward movement to make it out of the suspended state, so as to observe and calculate the elastic recovery rate of the sample. When it is necessary to test again, the support block 8 is driven by the cylinder 6 to reset. When conducting a series of elastic tests under different load conditions, there is no need to operate manually one by one. The state of the weight can be quickly adjusted by controlling the action of the cylinder 6, thereby improving the continuity and efficiency of the test.
