Description

Technical Field

[0001] The invention relates to the technical field of fabric detection, in particular to a device for detecting the tensile properties of textile fabrics. Background Art

[0002] In the current fabric textile processing technology, it is usually necessary to use a fabric tensile performance tester to perform tensile testing on the produced fabrics. Its main purpose is to assess the elongation at fixed force, elongation at fixed force, elastic recovery rate and plastic deformation rate, and then determine the tensile breaking strength of the fabric, and then grade the quality of the produced fabrics.

[0003] After searching the Chinese patent with publication number CN215414821U, a fabric tensile performance testing device is disclosed. By setting a lower component, an upper component and a fastening screw, the upper component can slide on the column, and the compression spring can support and reset the upper component. By adjusting the fastening screw, the fabric placed between the upper component and the lower component is clamped to play a clamping role to prevent the fabric placed on the clamping component from falling off. By setting a double-headed screw, a slider, a column, etc., the double-headed screw is rotated to move the slider, the slider drives the column to move, the column movement drives the clamping assembly to move, the clamping assembly clamps the fabric, and then stretches the fabric to achieve the detection purpose.

[0004] Based on the above search and combined with the prior art, it is found that when the existing fabric tensile performance testing device is used to test the fabric, it cannot pre-treat the fabric before clamping, and directly places the fabric in the clamping structure position, which causes the fabric to easily have wrinkles that affect the test data.

[0040] Working principle: When testing the tensile properties of textile fabrics, the fabric to be tested is placed at the top center of the test table 3, and the hydraulic rod 6 is started. The hydraulic rod 6 pushes the clamping frame 5 downward, and the side clamping plates 28 connected to the telescopic tube 3 27 on the four mounting plates 8 at the bottom of the clamping frame 5 first contact and connect with the center of the fabric. As the clamping frame 5 continues to descend, the inclined telescopic tube 3 27 shrinks, and the side clamping plates 28 contact the fabric and slide on it. The four side clamping plates 28 are pushed flat from the center of the fabric to the outer circle to remove the wrinkles on the fabric. , the side clamping plate 28 gradually approaches the upper clamping plate 25. When the upper clamping plate 25 contacts the top of the lower clamping plate 16, the side clamping plate 28 also enters the splicing groove 32 of the upper clamping plate 25 as the telescopic tube 3 27 contracts, and cooperates with the upper clamping plate 25 and the lower clamping plate 16 to clamp and fix the fabric. The magnetic strip 33 on one side of the upper clamping plate 25 is adsorbed and fixed to the outer wall of one side of the lower clamping plate 16. When the clamping frame 5 continues to descend, it pushes the detection platform 3 to slide down inside the base 2. The rack 10 on the internal limit plate 12 of the base 2 and the gear on the outer wall of the screw 9 on the detection platform 3 are engaged with each other. When the wheel 13 is meshed and the testing platform 3 descends, the rack 10 drives the screw 9 to rotate through the gear 13, thereby driving the slider 20 to slide, so that the four lower clamping plates 16 cooperate with the upper clamping plate 25 to clamp the fabric and stretch it from four directions of up, down, left and right at the same time, and cooperate with the pressure measuring device 19 on the lower clamping plate 16 to measure the tension, so as to calculate the tensile performance data of the fabric. After the slider 20 slides for a distance, the lower clamping plate 16 contacts the support plate 17 in the installation groove, and the inclined groove 21 at the bottom of the lower clamping plate 16 contacts the inclined surface 1 of the support plate 17. 8 contacts, the lower clamping plate 16 is lifted up, the telescopic tube 23 is stretched, and the upper clamping plate 25 is also lifted up, the spring 230 on the support rod 29 contracts, the upper clamping plate 25 cooperates with the lower clamping plate 16 to make the fabric suspended in the air, and the tensile performance test data is more accurate. After the tensile test is completed, the hydraulic rod 6 is controlled to reset the clamping frame 5, and the test table 3 is also reset under the action of the telescopic tube 11, and the screw rod 9 rotates in the opposite direction to drive the slider 20 and the lower clamping plate 16 to reset, and the upper clamping plate 25 is separated from the lower clamping plate 16 to take out the fabric and replace it to prepare for the next fabric test.

[0041] The upper clamping plate 25 and the side clamping plate 28 are both provided with connecting protrusions 31, and the outer wall of the lower clamping plate 16 is provided with connecting grooves 24, so that the upper clamping plate 25 and the side clamping plate 28 cooperate with the lower clamping plate 16 to clamp the fabric more firmly and not easily fall off. The spring 1 22 arranged on the outer wall of the telescopic tube 23 is convenient for the lifting and resetting of the lower clamping plate 16. The rotation of the screw 9 is completed by the meshing of the rack 10 on the limit plate 12. When the upper clamping plate 25 and the lower clamping plate 16 are close to each other, they are adsorbed and fixed by the magnetic strip 33. When the lower clamping plate 16 moves, the upper clamping plate 25 is also driven to slide in the slide rail at the bottom of the clamping frame 5 through the adsorption and limitation of the magnetic strip 33.

[0042] A two-way fan 14 is installed at the bottom of the testing table 3, and an air volume meter 26 is installed at the bottom of the clamping frame 5. When the fabric is clamped, the two-way fan 14 acts to exhaust air to the top of the testing table 3 through the air outlet pipe, and adsorbs and fixes the center position of the fabric to facilitate the clamping of the fabric. When testing some tougher fabrics, pulling and breaking will cause greater damage to the equipment. The two-way fan 14 can be used to supply air from the air outlet pipe to the top of the testing table 3, and the flowing air passes through the fabric mesh and is measured by the air volume meter 26 at the bottom of the clamping frame 5. Based on the comparison of the measurement data of the air volume meter 26 before and after stretching, the ventilation performance caused by the change of the mesh before and after the stretching of the fabric is recorded, so as to assist in the detection of the stretching performance of the fabric. A filter 15 is provided on the testing table 3 to filter the flowing air to ensure ventilation while preventing the fabric from being sucked into the two-way fan 14.
