The camshaft is used to drive the crank connecting rod, so that the interior of the two side piston groups can be respectively in a state of pressurization and negative pressure, and then the contraction of the reciprocating cylinder is controlled by hydraulic pressure. The contraction of the reciprocating cylinders on both sides promotes the reciprocating motion of the L-shaped slide, thereby driving the collection channel to reciprocate and perform friction detection. The driving effect is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1:

[0034] Please refer to the attached figure in the instruction manual. Figures 1 to 9 As shown:

[0035] The present invention proposes an adjustable elastic fabric friction detection device, comprising: a main detection frame 1, wherein two groups of L-shaped slide seats 101 are slidably arranged on the top side of the main detection frame 1 in cooperation with a guide rail, and spring rods 102 are fixedly arranged on the top of the L-shaped slide seats 101; a driver 2 is fixedly arranged below the inner surface of the main detection frame 1; a collecting channel 3, wherein protruding structures are arranged above both sides of the collecting channel 3, and the protruding structures are slidably arranged on the outside of the spring rod 102; a baffle for limiting position is arranged on the top of the spring rod 102, and a spring for pushing the collecting channel 3 upward is sleeved on the outside of the spring rod 102; an exhaust channel 4 is arranged at the bottom of the collecting channel 3 in cooperation with a pipeline connection; an upper frame 5 is fixedly arranged on the top of the main detection frame 1; two groups of lower pulling seats 7 are slidably arranged on the top of the main detection frame 1 in cooperation with the guide rail, two groups of vertical fixed rods 701 are fixedly arranged on the top of both sides of the lower pulling seat 7, and an upper pulling seat 8 is slidably arranged outside the vertical fixed rod 701.

[0037] Among them, sliding pistons 202 are slidably arranged inside the side piston group 201; a camshaft 203 is rotatably arranged in the driver 2, and there are two groups of eccentric positions of the camshaft 203 and they are symmetrical with the axial direction of the camshaft 203 as the base point; two groups of crank connecting rods 204 are rotatably arranged outside the camshaft 203, and the outer ends of the crank connecting rods 204 are each connected to a group of sliding pistons 202; a driving motor 205 is fixedly arranged on the rear side of the driver 2, and the driving motor 205 is transmission-connected to the camshaft 203.

[0038] Among them, the middle of the top of the collecting channel 3 is an open structure, and V-shaped corrugated structures are arranged on both sides of the top of the collecting channel 3, and the opening positions of the corrugated structures on both sides are staggered; four groups of plug-in grooves 301 are fixedly arranged at the corners on both sides of the collecting channel 3, and color retention plates 302 are inserted in the two groups of plug-in grooves 301 on the same side; the top surface of the collecting channel 3 is higher than the top surface of the lower pulling seat 7.

[0039] Among them, two groups of exhaust fans 401 are fixedly arranged in the middle of both ends of the exhaust channel 4; two openings are opened at the bottom of both sides of the exhaust channel 4, and wedge-shaped grids 402 are installed in the openings; the outer sleeves of both ends of the exhaust channel 4 are provided with installation sleeves 403 for locking the wedge-shaped grids 402, and the installation sleeves 403 can be fixed on the outside of the exhaust channel 4 through connecting pins 404; the top of the connecting pin 404 is integrally provided with an annular structure.

[0040] Among them, four groups of guide rods 501 are fixedly arranged at the middle bottom of the upper frame 5, and a cross-shaped frame body is fixedly arranged at the bottom of the guide rods 501; a positioning screw 502 is rotatably arranged in the middle of the four groups of guide rods 501, and a screw motor 503 is fixedly arranged on the top of the upper frame 5, and the screw motor 503 is transmission-connected with the positioning screw 502; a lifting and landing platform 6 is slidingly arranged outside the four groups of guide rods 501, and the lifting and landing platform 6 is threadedly connected with the positioning screw 502.

[0041] Among them, four groups of rotating connecting rods 601 are hinged on both sides of the landing platform 6, and the outer ends of the rotating connecting rods 601 are hinged above the upper pulling seat 8; a counterweight 801 is fixedly set in the middle of the top of the upper pulling seat 8; the adjacent surfaces of the upper pulling seat 8 and the lower pulling seat 7 are both provided with corrugated rubber pads.

[0042] Among them, two sets of landing gears 9 are slidably arranged inside the main detection frame 1, and the bottom of the landing gear 9 is slidably connected with the top of the upper pulling seat 8 by a guide rail.

[0043] Among them, two sets of limit blocks 901 are fixedly arranged at the bottom of the landing gear 9, and the distance between the sides of the two sets of limit blocks 901 is greater than the length of the landing platform 6, so as to ensure that the landing platform 6 is raised to the highest Figure 1When the limit block 901 contacts the lower pulling seat 7, the lifting platform 6 can no longer move, and the control program detects that the power consumption of the screw motor 503 increases and stops automatically.

[0044] like Figure 1-4 As shown, when testing a stretch fabric sample, first install two clips outside the narrow sides of the sample for weighting, and then spread the stretch fabric flat on the upper surface of the two sets of lower pulling seats 7, and the stretch fabric cooperates with the weighting of the clips on both sides to keep it flat;

[0045] Then, the screw motor 503 is started to drive the positioning screw 502 to rotate, and the positioning screw 502 drives the lifting and lowering platform 6 to descend. The descent of the lifting and lowering platform 6 drives the rotating connecting rod 601 to descend. At the same time, the rotating connecting rod 601 descends and the landing gear 9 naturally descends under the influence of gravity, and the upper pulling seat 8 is dropped to the top of the lower pulling seat 7, and the elastic cloth is clamped and fixed by the lower pulling seat 7 and the upper pulling seat 8. Then, the screw motor 503 continues to work, and the landing platform 6 continues to descend, forcing the upper pulling seats 8 and the lower pulling seats 7 on both sides to extend outward, stretching the elastic cloth, and then stretching the elastic cloth. After stretching, the resistance of the screw motor 503 is large and the voltage will increase, and it can stop working at this time; during this period, the lowering of the lifting and lowering platform 6 and the rotating connecting rod 601 will push the lower pulling seat 7 outward according to the principle of the slider mechanism, and the natural contraction of the elastic cloth produces a force in the opposite direction. Through the influence of friction, the two forces are locked with each other to ensure that the elastic cloth is fixed more tightly.

[0046] Embodiment 2:

[0047] On the basis of Example 1, when it is necessary to detect and collect hair balls, the pressure generated by the stretching of the elastic fabric will press the collecting channel 3 downward to keep it taut, and then the driving motor 205 is started to drive the camshaft 203 to rotate, and the camshaft 203 drives the crank connecting rods 204 on both sides to move, so that the sliding pistons 202 on both sides reciprocate, and the movement directions of the two groups of sliding pistons 202 are synchronized, so that the interiors of the two groups of side piston groups 201 are respectively in a state of pressurization and negative pressure. When the side piston group 201 is pressurized, the internal hydraulic oil enters the reciprocating cylinder 103 on the same side to open the reciprocating cylinder 103 on this side, and at the same time, the reciprocating cylinder 103 on the other side contracts, and the contraction of the reciprocating cylinders 103 on both sides promotes the reciprocating movement of the L-shaped slide 101, thereby driving the collecting channel 3 to reciprocate and perform friction detection; during the reciprocating movement of the collecting channel 3, the corrugated structure at the top of the collecting channel 3 rubs against the surface of the elastic fabric, so that the wear resistance of the elastic fabric and the pilling situation can be detected;

[0048] The hair balls generated by friction will be guided by the corrugations on the surface of the collecting channel 3 and converge toward the middle;

[0049] The suction force generated by the exhaust fan 401 can be used to suck the hair balls generated by the elastic fabric into the collection channel 3. The hair balls pass through the collection channel 3 and enter the exhaust channel 4, where they are intercepted and collected by the wedge-shaped grid 402.

[0050] When it is necessary to count the balls, the connecting pin 404 is pulled out, and the mounting sleeve 403 is removed to take out the wedge-shaped grid frame 402. The amount of balls stored in the wedge-shaped grid frame 402 can be measured to determine the amount of pilling of the stretch fabric.

[0051] Embodiment 3:

[0052] On the basis of Example 1, Figure 6-7 As shown, the color retaining plate 302 can be selectively installed directly in the plug-in slot 301. When the color retaining plate 302 is involved in the friction, if the elastic fabric fades, it will remain on the surface of the color retaining plate 302, so as to observe the fading situation. Finally, the color retaining plate 302 can be cleaned and dried and can be used again.

[0053] The color retention plate 302 is made of white material, which is convenient for color fading detection of colored fabrics. If it is white fabric, a special black color retention plate 302 is used for detection.
