An installation frame 12 is fixedly connected to the workbench 3, a swing rod 13 is hinged in the installation frame 12, a clamping block 14 is fixedly connected to one end of the swing rod 13, a pressing block 16 is fixedly connected to the other end of the swing rod 13, a spring 15 is fixedly connected between the swing rod 13 and the workbench 3, a fixed block 11 is installed on the workbench 3 and is arranged beside the guide wheel 6, a wire groove is opened on the fixed block 11, a first trigger 17 is installed on the workbench 3, a second trigger 18 is installed on the base 1, a counter 19 is installed on the side wall of the workbench 3, the counter 19 is connected to the first trigger 17 through a data cable and is also connected to the second trigger 18 through a data cable; when detecting the anti-slip effect of the cloth, first press the swing rod 13, the spring 15 is compressed by force, so that the clamping block 14 is clamped and fixed in the wire groove, so that the rope 7 can be fixed, then straighten the rope 7, place the placement groove 8 above the cloth, and place a counterweight 9 in the placement groove 8, then press the swing rod 13 again, so that the clamping block 14 disengages from the wire groove, so that the plumb bob 10 drives the counterweight 9 to move stably, and the plumb bob 10 starts to fall. At the same time, under the action of the spring 15 rebounding, the pressing block 16 presses the first trigger 17, and the first trigger 17 transmits a signal to the counter 19, triggering the counter 19 to start counting. When the plumb bob 10 falls to contact the second trigger 18, the second trigger 18 transmits a signal to the counter 19, and the counter 19 terminates counting. Thus, it is possible to determine the sliding time of the counterweight 9 on the cloth from the start of the fall of the plumb bob 10 to the end of the fall, and further, according to mechanical analysis, determine the magnitude of the cloth friction coefficient, thereby realizing the detection of the anti-slip effect of the cloth and ensuring the accuracy of the detection result at the same time.

[0020] Two fixing plates 20 are fixedly connected to the workbench 3, a pressing frame 21 is rotatably installed between the two fixing plates 20, a scale marking 23 is fixedly connected to the top side of the pressing frame 21, a plurality of positioning pins 22 are fixed to the bottom side of the pressing frame 21, and the plurality of positioning pins 22 are arranged at equal intervals; when clamping and fixing the cloth, first place the cloth to be detected on the workbench 3, and then press the pressing frame 21 downward. With the cooperation of the positioning pins 22, the cloth can be quickly fixed, avoiding the deviation of the cloth during the detection and facilitating the subsequent detection operation of the cloth.

[0021] Working principle: Since the existing friction detection device cannot quickly and effectively fix the cloth when detecting the anti-slip effect of the cloth, and at the same time, during the detection, the moving state of the counterweight used for detection is unstable, which cannot ensure the accuracy of the detection result. Therefore, an anti-slip cloth friction detection device is proposed for the above problems. When detecting the anti-slip effect of the cloth, first press the swing rod 13, the spring 15 is compressed by force, so that the clamping block 14 is clamped and fixed in the wire groove, so that the rope 7 can be fixed. Then straighten the rope 7, place the placement groove 8 above the cloth, and place the counterweight 9 in the placement groove 8. Then press the swing rod 13 again, so that the clamping block 14 disengages from the wire groove, so that the plumb bob 10 drives the counterweight 9 to move stably, and the plumb bob 10 begins to fall. At the same time, under the action of the spring 15 rebounding, the pressing block 16 presses the first trigger 17, and the first trigger 17 transmits the signal to the counter 19. The model of the first trigger 17 is CD-2A, which triggers the counter 19 to start counting. The model of the counter 19 is JS48J. When the plumb bob 10 falls to contact the second trigger 18, the second trigger 18 transmits the signal to the counter 19. The model of the second trigger 18 is CD-7A, and the counter 19 terminates counting. Thus, it can be determined the sliding time of the counterweight 9 on the cloth from the start of the plumb bob 10 falling to the end of the fall, and then the coefficient of friction of the cloth can be determined according to mechanical analysis, so as to realize the detection of the anti-slip effect of the cloth and ensure the accuracy of the detection result at the same time.

[0022] When clamping and fixing the cloth, first place the cloth to be detected on the workbench 3, and then press down the pressing frame 21. With the cooperation of the positioning pins 22, the cloth can be quickly fixed, avoiding the cloth from shifting during the detection, which is convenient for subsequent detection operations on the cloth.
