And (3) performing air blowing work: the motor 5 drives the second gear 19 to rotate through the output shaft, the second gear 19 rotates to drive the second rack 26 to slide on the hanging bracket 3, when the second rack 26 moves downwards, the second rack 26 moves to downwards extrude the air cylinder 12 through the first connecting block 18, so that air in the air cylinder 12 is blown out through the air nozzle 13, dust and impurities on the fabric on the detection table 7 are blown out, and the situation that the fabric is damaged when the surface of the fabric is left by foreign matters during a friction experiment to cause friction is avoided, so that the detection result is influenced.

The paving work is carried out: when the second rack 26 drives the blowing work to be carried out, the upper end of the pull rope 6 is pulled to descend through the second connecting block 21, the pull rope 6 can pull the shift lever 35 to slide in the third sliding groove 34, the movement of the shift lever 35 can drive the toothed ring 46 to rotate clockwise, the rotation of the toothed ring 46 can drive the fourth gear 45 to rotate clockwise, the rotation of the fourth gear 45 can drive the third rack 36 to slide outwards of the detection platform 7, the sliding of the third rack 36 can drive the pull rod 37 to move outwards simultaneously, so that the pull rod 37 can pull the sliding frame 40 to pull the smearing rod 44 to move outwards, the movement of the smearing rod 44 can smear the fabric outwards from the middle, when the smearing rod 44 moves outwards, the stretching spring 43 is arranged, the smearing rod 44 can be pulled outwards while being smeared outwards, the function of spreading the fabric in the vertical and horizontal directions is realized, and the fabric can be more flatly spread on the detection platform 7, the friction block 20 can be ensured to be better contacted with the fabric, so that the detection effect is better.

The fixed module works: when the pull rod 37 drives the troweling rod 44 to trowel, the pressing plate 47 is driven to move outwards at the same time, due to the right triangle of the pressing plate 47, the pressing ring 8 is pushed to move downwards on the fixing rod 48 through the bevel edge of the pressing plate, the pressing ring 8 drives the needle rod 50 to move downwards at the same time, the needle rod 50 drives the clamping needle 33 to move downwards at the same time, the clamping needle 33 is inserted into the needle hole 39 of the fixing lug 38, so that the fabric is fixed on the detection table 7, and the situation that the fabric is stretched and wrinkled due to the movement of the friction block 20 when the rubbing work is carried out is prevented, so that the fabric is broken, or the fabric is stacked together, thereby influencing the experiment and the experiment effect.

The friction work is carried out: when the second gear rack 26 moves to the lowest end, the first connecting block 18 moves to the lowest end of the second sliding chute 17 and cannot move downwards continuously, at the moment, the friction block 20 abuts against the upper end of the fabric of the detection table 7, the second spring 30 is compressed a little, the second gear 19 starts to be meshed with the convex teeth 23, along with the continuous rotation of the second gear 19, the second gear 19 can push the convex teeth 23 to move towards the second gear rack 26, the convex teeth 23 can push the first spring 25 to push the second connecting block 21 to push the second gear rack 26 downwards, so that the second gear 19 is kept not meshed with the second gear rack 26, and meanwhile, the first gear 4 is meshed with the second gear 19, at the moment, the rotation of the second gear 19 starts to drive the first gear 4 to rotate, the rotation of the first gear 4 can drive the sliding column 11 to reciprocate leftwards and rightwards through the guide rail groove 9, because the swinging rod 10 is rotatably connected to the second gear rack 26 through the rotating seat 15, the movement of the sliding column 11 can drive the swinging rod 10 to reciprocate on the rotating seat 15, thereby the pendulum rod 10 can drive the reciprocal swing of bull stick 28, bull stick 28 can drive the reciprocal reciprocating motion on the surface fabric of friction piece 20, thereby realize the function of friction, when bull stick 28 reciprocating motion, owing to be provided with rack one 22, at every turn when bull stick 28 moves the position of rack one 22, rack one 22 begins to mesh with gear three 27, thereby drive gear three 27 and rotate, gear three 27's rotation can drive bull stick 28 and rotate the rotation of bull stick 28 and can drive friction piece 20 and rotate, thereby realize the rotational friction when realizing the reciprocal friction, can improve the abundant degree of friction type, further improve the effect of friction.
