[0002] Gray yarn usually refers to yarn that has been processed by a specific process and presents a gray tone. This yarn can be made of a single fiber or a blend of multiple fibers. When testing the wear resistance of gray yarn fabrics, the Martindale method is generally used. The wear resistance of the sample is tested by rubbing the sample on the surface of a standard abrasive (usually silk or cotton cloth) and applying pressure through a weight.

[0016] Compared with the prior art, the present invention provides a gray yarn fabric wear resistance testing mechanism, which has the following beneficial effects: 1. The gray yarn fabric wear resistance testing mechanism places the clamping cover into the hoop, and then places the gray yarn fabric to be tested into the clamping cover; then the clamping cover is driven to rotate by the screwing assembly, so that the clamping cover and the docking plate are spirally connected together, and the clamping force of the clamping plate and the inner wall of the circular groove 2 on the gray yarn fabric is guaranteed by the elasticity of the spring 3, so that the installation of the gray yarn fabric can be completed, thereby achieving the purpose of facilitating the replacement of the gray yarn fabric to be tested; 2. The gray yarn fabric wear resistance testing mechanism drives the waste roller to rotate through the second motor to reel up the used standard friction agent, and moves the standard friction agent on the surface of the U-shaped frame, and the unused standard friction agent moves to the bottom of the U-shaped frame; and in the process, the friction plate rubs the friction disc, and the insert is stuck in the V-shaped groove of the friction disc to ensure the rotation resistance of the friction agent roller and the friction disc, prevent the standard friction agent from being released excessively, and keep the standard friction agent at the bottom of the U-shaped frame tight. When the standard friction agent on the friction agent roller is used up, the bolt is unscrewed, and the friction plate is pushed to the left, so that the friction agent roller can be removed and replaced with a new friction agent roller; similarly, the second motor can be disassembled from the left support, and the waste roller can be replaced, so as to achieve the purpose of facilitating the replacement of the standard friction agent at the bottom of the U-shaped frame; 3. The gray yarn fabric wear resistance testing mechanism, when the gray yarn fabric is clamped and fixed by the lower clamping assembly and the upper clamping assembly, the output end of the second cylinder is extended to drive the slide and the rack plate to move to the right, drive the gear and the hollow disk to rotate half a circle, so that the clamping disk is rotated to the bottom of the hollow disk, and then the output end of the first cylinder is contracted to drive the support plate to move downward, the hollow disk moves downward synchronously, and the clamping disk is inserted into the inside of the second circular groove, so that the pad and the clamping disk clamp the gray yarn fabric in the vertical direction, and the gray yarn fabric at the opening of the second circular groove is kept flat under the clamping action of the pad and the clamping disk, thereby ensuring that the wear resistance testing process of the gray yarn fabric is more reliable; 4. The wear resistance testing mechanism of the gray yarn fabric is that after the lower clamping assembly and the upper clamping assembly clamp and fix the gray yarn fabric, the hollow disk is turned over so that the clamping cover is above the hollow disk. Under the action of gravity, the pressure plate fits on the surface of the pressure sensor to squeeze the pressure sensor. At this time, the squeezing force applied to the pressure sensor is the initial squeezing force, and then continues to extend through the output end of the cylinder, thereby driving the gray yarn fabric at the second circular groove to fit on the standard friction agent at the bottom of the U-shaped frame. At this time, the squeezing force applied to the pressure sensor increases, which is a dynamic squeezing force. Therefore, the difference between the initial squeezing force and the dynamic squeezing force reflects the squeezing force between the gray yarn fabric and the standard friction agent. Compared with adjusting the squeezing force between the gray yarn fabric and the standard friction agent by weights, the adjustment process is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A driving wheel 908 is sleeved on the outside of the connecting shaft 904 and the second convex strip 905. The driving wheel 908 penetrates and is rotatably connected to the box-shaped seat 100. A notch matching the second convex strip 905 is opened on the inner wall of the driving wheel 908, so that when the driving wheel 908 rotates, the connecting shaft 904 and the second convex strip 905 can rotate synchronously, and in this process, the connecting shaft 904 can move up and down relative to the driving wheel 908.

[0036] A driven sprocket 909 is fixedly mounted on the circumferential surface of the driving wheel 908, and three driven sprockets 909 in the same row are connected by an annular chain 910.

Thus, the driving sprocket 912 is driven to rotate by the motor 3 911, and the driving action of the annular chain 910 and the driven sprocket 909 is coordinated to drive a row of driving wheels 908 to rotate synchronously.

[0037] When in use, first, place the clamping cover 801 into the hoop 902, insert the convex strip 803 into the arched portion 903, and then place the gray yarn fabric to be tested into the clamping cover 801; Then, the output end of the second cylinder 607 is extended, driving the slide 604 and the rack plate 606 to move rightward, driving the gear 703 and the hollow disk 701 to rotate half a circle, so that the clamping disk 711 rotates to the bottom of the hollow disk 701, and then the output end of the cylinder 1 601 is contracted, driving the support plate 600 to move downward, and the hollow disk 701 moves downward synchronously, and the clamping disk 711 is inserted into the inside of the second circular groove 802, so that the pad 901 and the clamping disk 711 clamp the gray yarn fabric in the vertical direction, and the clamping disk 711 and the inner wall of the second circular groove 802 clamp the gray yarn fabric from the side; As the hollow plate 701 continues to move downward, the spring three 710 is first squeezed and contracted until the bottom edge of the docking plate 705 fits on the top edge of the clamping cover 801, and then the spring four 907 is squeezed and contracted, and the docking plate 705 and the clamping cover 801 move downward synchronously, and the elasticity of the spring four 907 ensures the squeezing force between the docking plate 705 and the clamping cover 801; Then, the motor 3 911 drives the active sprocket 912 to rotate, and cooperates with the transmission effect of the annular chain 910 and the driven sprocket 909 to drive a row of driving wheels 908 to rotate synchronously, and drives the connecting shaft 904 and the second convex strip 905 to rotate, thereby driving the pad 901, the hoop 902 and the arched portion 903 to rotate, thereby driving the clamping cover 801 to rotate relative to the docking plate 705, so that the clamping cover 801 and the docking plate 705 are spirally connected together, and the distance between the bottom of the docking plate 705 and the clamping plate 711 is reduced, and the spring 3 710 is squeezed and contracted again. Through the elasticity of the spring 3 710, the clamping force of the clamping plate 711 and the inner wall of the circular groove 2 802 on the gray yarn fabric is guaranteed; Then, the output end of the cylinder 1 601 is extended to drive the support plate 600 to rise, so that the clamping cover 801 is pulled out from the hoop 902, and then the output end of the cylinder 2 607 is contracted to drive the slide 604 and the rack plate 606 to move to the left, so that the hollow disk 701 and the gear 703 rotate half a circle, so that the clamping disk 711 is deflected to the top of the hollow disk 701, that is, the clamping cover 801 is deflected to the top of the hollow disk 701, and under the action of gravity, the pressure plate 707 is attached to the surface of the pressure sensor 704; the output end of the cylinder 1 601 continues to extend, thereby driving the gray yarn fabric at the circular groove 2 802 to attach to the standard friction agent at the bottom of the U-shaped frame 401, and the extrusion force exerted on the pressure sensor 704 reflects the extrusion force between the gray yarn fabric and the standard friction agent from the side; Then, the motor 301 drives the turntable 302 to rotate, and the push rod 303 performs a circular motion, driving the butterfly plate 200 to shake, so that the standard friction agent moves on the surface of the gray yarn fabric to perform friction detection; The motor 2 504 drives the waste roller 503 to rotate, reeling the used standard friction agent, and moving the standard friction agent on the surface of the U-shaped frame 401, and the unused standard friction agent moves to the bottom of the U-shaped frame 401; and in the process again, the friction plate 5092 rubs the friction disc 508, and the insert 5096 is stuck in the V-shaped groove of the friction disc 508 to ensure the rotation resistance of the friction agent roller 507 and the friction disc 508, prevent the standard friction agent from being released excessively, and keep the standard friction agent at the bottom of the U-shaped frame 401 tight. When the standard friction agent on the friction agent roller 507 is used up, the bolt 5094 is unscrewed, and the friction plate 5092 is pushed to the left, and the friction agent roller 507 can be removed and replaced with a new friction agent roller 507; similarly, the motor 2 504 can be disassembled from the left support 501, and the waste roller 503 can be replaced.
