Detailed implementation manners

[0022] The following will further describe the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0023] An embodiment of the present application discloses a greige fabric tensile property testing machine. Refer to Figure 2 Figure 3 , a greige fabric tensile property testing machine includes a testing table 1 and a greige fabric sample 2, wherein the greige fabric sample 2 is located at the top of the testing table 1, and a tensile testing mechanism 3 for detecting the tensile property of the greige fabric is arranged on the top of the testing table 1. It also includes

[0024] a clamping mechanism 4, which is located on the side wall of the tensile testing mechanism 3 for clamping and fixing the greige fabric sample 2;

[0025] The clamping mechanism 4 includes a plurality of limiting clamping plates 401 and a pressing component 6. The tensile testing mechanism 3 includes two tensile rollers 303. The bottoms of the plurality of limiting clamping plates 401 are installed on the side walls of the two tensile rollers 303 through a size adjustment component 5, and the pressing component 6 is installed on the side walls of the plurality of limiting clamping plates 401;

[0026] The pressing component 6 includes a plurality of stable pressing plates 601 and a plurality of lifting units 7. One ends of the plurality of stable pressing plates 601 are respectively installed on the side walls of the plurality of limiting clamping plates 401 through the plurality of lifting units 7;

[0027] The lifting unit 7 includes a lifting chute 701, a support rod 702, a lifting slider 703 and a spring 704. The lifting chute 701 is formed on the side wall of the limit clamping plate 401. The two ends of the support rod 702 are respectively fixedly connected to the two ends of the lifting chute 701. One end of the stable pressing plate 601 is slidably connected to the side wall of the support rod 702 through the lifting slider 703. The two ends of the spring 704 are respectively fixedly connected to the top of the lifting chute 701 and the top of the lifting slider 703;

[0028] The pressing assembly 6 further includes a plurality of soft pads 8. The tops of the plurality of soft pads 8 are fixedly connected to the bottoms of the plurality of stable pressing plates 601, and the plurality of soft pads 8 are made of rubber;

[0029] The stretching detection mechanism 3 further includes two support plates 301 and two servo motors 302. The two support plates 301 are symmetrically and fixedly connected to the top of the detection table 1. The two servo motors 302 are respectively fixedly connected to the side walls of the two support plates 301. The two stretching rollers 303 are respectively rotatably connected to the middle parts of the two support plates 301, and the output ends of the two servo motors 302 are respectively fixedly connected to one ends of the two stretching rollers 303 through rotation through the side walls of the two support plates 301;

[0030] In this embodiment, first, the sliding lifting slider 703 is supported by the provided support rod 702 so that it slides upward in the provided lifting chute 701. The upward sliding of the lifting slider 703 drives the connected stable pressing plate 601 to slide upward. At this time, the two ends of the fabric sample 2 are placed between the limit clamping plates 401, and then the set lifting slider 703 is released and the provided spring 704 provides a force to make the lifting slider 703 reset and rebound downward. The downward rebound sliding of the lifting slider 703 drives the stable pressing plate 601 to rebound and slide downward to press and fix the fabric sample 2 on the side wall of the stretching roller 303, and the provided soft pads 8 made of rubber can increase the friction force of the contact surface between the stable pressing plate 601 and the fabric sample 2 for anti-slip and stability. In this way, it is convenient to stably press and fix the two ends of the fabric sample 2, so that there is no need to manually press and fix the fabric sample 2, and the operation is simple, convenient, time-saving and labor-saving;

[0031] Moreover, after the fabric sample 2 is fixed, at this time, the existing tensile testing system can be used to control the set servo motor 302 to start and provide a force to drive the stretching roller 303 to rotate under force in the middle of the support plate 301. The two stretching rollers 303 rotate in opposite directions to wind the fixed fabric sample 2 around the stretching roller 303 and straighten the fabric sample 2, and the continuous rotation of the stretching roller 303 applies a force to achieve the effect of detecting the tensile performance of the fabric sample 2.

[0032] Further, the size adjustment component 5 includes a plurality of adjustment chutes 501, a plurality of adjustment screws 502, and a plurality of moving sliders 503. The plurality of adjustment chutes 501 are symmetrically opened on the side walls of the two stretching rollers 303 respectively. The two ends of the plurality of adjustment screws 502 are rotatably connected to the two ends of the plurality of adjustment chutes 501 respectively. Threaded holes are formed in the middle parts of the plurality of moving sliders 503. The plurality of adjustment screws 502 are rotatably connected to the middle parts of the plurality of moving sliders 503 respectively by being fitted with the threaded holes. Moreover, the bottoms of the plurality of limiting clamping plates 401 are fixedly connected to the tops of the plurality of moving sliders 503;

[0033] On the basis of the above embodiment, according to the width size of the fabric sample 2, by rotating the provided adjustment screw 502, the moving slider 503 rotatably connected through the threaded hole fit is forced to slide in the opened adjustment chute 501. The moving slider 503 slides and opens, thereby driving the connected limiting clamping plate 401 to move and open on the side wall of the stretching roller 303. At this time, after one end of the fabric sample 2 is attached to the middle of the stretching roller 303, similarly, by reversely rotating the provided adjustment screw 502, the moving slider 503 is forced to move back elastically. The moving slider 503 moves back elastically, thereby driving the limiting clamping plate 401 to move back and close to clamp and hold the fabric sample 2. In this way, it is possible to easily adjust and change the width size of the clamping and fixing according to the use requirements to adapt to different use environments, facilitate clamping and fixing of fabric samples 2 with different width sizes, and thus facilitate the tensile test of different fabric samples 2.

[0034] The implementation principle of a greige fabric tensile property testing machine according to an embodiment of the present application is as follows: When in use, first, according to the width dimension of the greige fabric sample 2, by rotating the adjusting screw rod 502, the moving slider 503 that is rotationally connected through the threaded hole is forced to slide within the opened adjusting chute 501. By the sliding movement of the moving slider 503, it spreads open, driving the connected limit clamping plate 401 to move and spread open on the side wall of the stretching roller 303. At this time, after one end of the greige fabric sample 2 is attached to the middle of the stretching roller 303, similarly, by rotating the adjusting screw rod 502 in the reverse direction, the moving slider 503 is forced to rebound and move. By the rebound movement of the moving slider 503, it drives the limit clamping plate 401 to rebound and move to close and clamp the greige fabric sample 2. In this way, it can effectively and conveniently adjust and change the width dimension of the clamped and fixed part according to the usage requirements to adapt to different usage environments, facilitate the clamping and fixing of greige fabric samples 2 with different width dimensions, and thus facilitate the tensile property testing of different greige fabric samples 2. Secondly, after limiting the width dimension of the greige fabric sample 2, by the support rod 702, the sliding and lifting slider 703 is supported to slide upward within the opened lifting chute 701. By the upward sliding movement of the lifting slider 703, it drives the connected stable pressing plate 601 to slide upward. At this time, both ends of the greige fabric sample 2 are placed between the limit clamping plates 401, and then the lifting slider 703 is released and the spring 704 provides a force to make the lifting slider 703 be forced to reset and rebound downward. By the downward rebound movement of the lifting slider 703, it drives the stable pressing plate 601 to rebound and slide downward to press and fix the greige fabric sample 2 on the side wall of the stretching roller 303, and the soft pad 8 made of rubber can increase the friction force of the contact surface between the stable pressing plate 601 and the greige fabric sample 2 for anti-slip and stability. In this way, it can effectively and conveniently press and fix both ends of the greige fabric sample 2, so there is no need to manually press and fix the greige fabric sample 2, and the operation is simple, convenient, time-saving and labor-saving. Finally, after the greige fabric sample 2 is fixed, at this time, through the existing tensile testing system, the servo motor 302 can be controlled to start to provide a force to drive the stretching roller 303 to rotate in the middle of the support plate 301. By the reverse rotation of the two stretching rollers 303, the greige fabric sample 2 fixed on them is wound around the stretching roller 303 and the greige fabric sample 2 is straightened, and by continuously rotating and applying force by the stretching roller 303, the effect of testing the tensile property of the greige fabric sample 2 can be achieved.

[0035] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
