Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a device for testing the tensile strength of greige fabric. Background Technology

[0002] As is well known, the quality inspection of greige fabric is crucial in the textile industry. As the base material for subsequent printing, dyeing, and processing, the tensile strength of greige fabric directly affects the performance and quality of the final product. During the production of greige fabric, differences in raw materials and changes in textile process parameters can lead to changes in the tensile strength of the greige fabric. At the same time, during the storage and transportation of greige fabric, environmental factors or external forces such as squeezing and pulling may also affect its tensile properties. In order to ensure smooth subsequent processing and stable product quality, it is necessary to accurately test the tensile strength of greige fabric, thereby providing a basis for production and quality control.

[0003] Existing fabric tensile strength testing devices typically test the tensile strength of fabric by stretching it to the left and right, but cannot test other positions. This limited testing angle affects the accuracy of the test.

[0004] An existing patent (publication number: CN218646726U) discloses a device for testing the tensile strength of greige fabric, aiming to solve the problem of a single testing angle. The key technical points are: a device for testing the tensile strength of greige fabric includes a testing platform. Support legs are fixedly installed on the front and rear sides of the lower left and right sides of the testing platform. A slide rail is fixedly installed on the rear side of the upper middle section of the testing platform. A sliding tensioning device is installed inside the slide rail. A first upright plate is fixedly installed on the rear side of the upper left section of the testing platform. A feeding roller is movably connected to the front end of the first upright plate. A fabric body is movably connected to the outer surface of the feeding roller. This invention uses two tensioning rollers to reciprocate up and down, squeezing the fabric body so that the middle of the fabric body is in a tensile state for tensile strength testing. The fabric body can be stretched in four directions (up, down, left, and right), enabling multi-directional tensile strength testing and multi-angle testing, ensuring testing accuracy.

[0031] Specifically, as Figure 3 Indicated, testing mechanism 3 includes air supply assembly 31 and stretching assembly 32, air supply assembly 31 is communicated at the top of air supply pipe 24, and stretching assembly 32 is communicated at the two sides of air supply assembly 31.

[0032] Specifically, as shown in Figure 4 the gas delivery assembly 31 includes a shunt pipe 311, a flow guide pipe 312, an atomizing nozzle 313, a gas pressure expansion pipe 314, and a shunt port 315. The shunt pipe 311 is connected to the top of the gas delivery pipe 24. The flow guide pipe 312 is connected to both sides of the shunt pipe 311.

[0040] In the embodiment: by setting the limiting ring 6 and the reset tension spring 7, the limiting ring 6 can cooperate with the reset tension spring 7, and by clamping the limiting ring 6 with the air pressure expansion pipe 314 and the flow guide pipe 321 respectively, the reset tension spring 7 can be stretched when the air pressure expansion pipe 314 is stretched, and when the air pressure expansion pipe 314 stops stretching, the two limiting rings 6 can be reset by the tension of the reset tension spring 7. By setting the buffer pad 8 and the pressure tester 9, the buffer pad 8 can buffer the clamping of the contact plate 323 and the clamping plate 325 on the fabric, and can transmit the pressure to the pressure tester 9, so that the pressure tester 9 can detect the pressure of the contact plate 323 and the clamping plate 325 on the fabric. The user can observe the pressure of the contact plate 323 and the clamping plate 325 on the fabric in real time, so as to avoid the fabric from being accidentally loosened due to insufficient pressure.
