Of course, the specific structure of the fixing member 200 is not limited thereto.

The swinging member 300 has a bar-shaped through-hole 310 through which the textile ribbon 500 passes, and the weight member has a second connecting portion for detachably connecting with the other end portion of the textile ribbon 500. One end of textile belt 500 is secured by fastener 200, and a weight is used to apply a weight force to the other end of textile belt 500, so that textile belt 500 is in a taut state. Different weights of the counterweight can be selected according to different test requirements.

The swinging member 300 is rotatably installed on the base 100, the swinging member 300 is driven by the first driver 320, the first driver 320 can drive the swinging member 300 to make reciprocating swinging, and the textile belt 500 also makes reciprocating swinging along with the swinging member 300 as the textile belt 500 passes through the strip-shaped through hole 310 of the swinging member 300.

Between the fixing member 200 and the swinging member 300 is provided a grinding wheel 110 for grinding the textile tape 500, and the grinding wheel 110 is mounted to the base 100 and driven by the second driver 120. In this embodiment, the second driver 120 is a driving motor, and the mounting heights of the fixing member 200 and the bar-shaped through-holes 310 are communicated, that is, the section of the textile belt 500 between the fixing member 200 and the swinging member 300 is in a horizontal state, and the polishing wheel 110 is located below the textile belt 500, so that it is more convenient to perform the wear resistance test and to adjust the pressure between the polishing wheel 110 and the textile belt 500 by changing the weight of the cloth.

Overall, novel wear-resisting testing arrangement 1000 simple structure, convenient to use can simulate out the loss condition of weaving area 500 in the in-service use process more really, and the wearability test result that it reachs more is close the in-service use condition, has higher persuasion and reliability, and is more accurate, reliable to weaving area 500's quality testing.

Further, referring to fig. 4 to 7, the swinging member 300 includes: a wobble plate 330, a first shaft 340, a second shaft 350, and a sleeve 360. The strip-shaped through hole 310 is opened in the swing plate 330.

The first shaft 340 is rotatably mounted on the base 100 of the novel wear testing apparatus 1000, one end of the first shaft 340 is fixedly connected to the swing plate 330, and the other end has a fitting member 341. The fitting member 341 has a fitting hole 342 provided in the axial direction of the first shaft body 340, a fitting groove 343 is recessed in the hole wall of the fitting hole 342, the fitting groove 343 is recessed in the radial direction of the first shaft body 340, and the fitting groove 343 extends in the axial direction of the fitting hole 342 and penetrates to the mouth of the fitting hole 342.

The sleeve 360 is installed on the base 100 and located between the first driver 320 and the first shaft 340, and the inner wall of the sleeve 360 has a guiding groove 361, and the guiding groove 361 extends in a spiral shape. The outer wall of the second shaft body 350 has a slider 351, the second shaft body 350 is slidably fitted to the sleeve 360 and the slider 351 is slidably fitted to the guide groove 361.

One end of the second shaft body 350 has a fitting 352 for fitting with the fitting hole 342, and an outer wall of the fitting 352 has a rib 353 for fitting with the fitting groove 343. The other end of the second shaft 350 is in transmission connection with the power output part of the first driver 320. The first driver 320 can drive the second shaft 350 to move close to and away from the first shaft 340, i.e. the driving fitting 352 is fitted with and separated from the fitting 341. In this process, the second shaft 350 is guided by the guide groove 361 to rotate. Namely: the engaging piece 352 is simultaneously in a rotating state during the engagement with the engaging piece 341, and the engaging piece 352 is simultaneously in a reverse rotating state during the separation from the engaging piece 341. With this design, the second shaft 350 is driven by the first driver 320 to move back and forth closer to and away from the first shaft 340, so that the fitting member 352 and the fitting member 341 can be engaged and disengaged while the swing plate 330 is driven to swing back and forth.

Here, it should be noted that, in the initial stage, the swing plate 330 is in a state of being vertically downward. When the engaging member 352 approaches the engaging member 341, it is in a rotating state, and once the engaging member 352 is smoothly engaged with the engaging member 341 (the engaging member 352 is engaged with the engaging hole 342, and the rib 353 is also engaged with the engaging groove 343), the engaging member 352 will drive the engaging member 341 to rotate together to swing the swing plate 330 upward. When the fitting member 352 moves away from the fitting member 341, the fitting member 352 rotates reversely and starts to separate from the fitting member 341, and the swing plate 330 starts to swing down. When the swing plate 330 is about to return to the vertically downward position, the fitting member 352 is completely separated from the fitting member 341, and the fitting member 341 is no longer restrained by the fitting member 352, and the swing plate 330 swings upward to the other side by inertia. Under the action of the weight, the swing plate 330 will quickly stabilize (i.e., quickly return to a vertically downward position) and will not swing continuously for a long time. When the swing plate 330 is substantially stabilized, the first driver 320 is used to re-drive the engaging member 352 to approach the engaging member 341, so as to enter the next swing-up period.

With the above design, the first driver 320 intermittently drives the engaging member 352 to approach and separate from the engaging member 341, so that the oscillating plate 330 oscillates in a reciprocating manner.

In this embodiment, the sleeve 360 further has a straight groove 362, the straight groove 362 is communicated with the guiding groove 361 and is located at an end of the guiding groove 361 far away from the fitting 352, and the straight groove 362 is disposed along an axial direction of the sleeve 360; before the engaging element 352 engages with the engaging element 341, the sliding block 351 is located in the straight groove 362, and the second shaft 350 does not rotate. When the engaging element 352 and the engaging element 341 are engaged, the slider 351 enters the guiding slot 361 from the straight slot 362, and the second shaft 350 starts to rotate, so as to drive the swing plate 300 to swing upward.

By this design, the fitting 352 can be more accurately fitted to the fitting 341. However, in order to make the fitting 352 more easily fit with the fitting 341, the fitting hole 342 and the cross section are circular, the cross section of the fitting groove 343 is fan-shaped, the fitting 352 is cylindrical and has an outer diameter slightly smaller than the diameter of the fitting hole 342, and the cross section of the rib 353 is also fan-shaped. The central angle degree corresponding to the rib 353 is smaller than the central angle degree corresponding to the matching groove 343. Specifically, in the present embodiment, the central angle degree corresponding to the rib 353 is half of the central angle degree corresponding to the matching groove 343, and the maximum angle of the swinging plate 330 swinging up each time is 60 °.

Further, referring to fig. 8 to 9, the plate surface of swing plate 330 has a notch 331 extending in the longitudinal direction thereof, and both ends of notch 331 penetrate both end walls of swing plate 330.

A strip-shaped through-hole 310 is located at the bottom of the groove 331 and is provided near the upper end of the swing plate 330. The second connecting portion is located at one end of the adjusting block 410 close to the strip-shaped through hole 310.

Referring to fig. 10 to 11, an outer wall of one end of the adjusting block 410, which is used for being connected to the pulling rope 430, is provided with an arc-shaped sliding groove 411 extending along a side wall thereof, the arc-shaped sliding groove 411 is slidably fitted with a connecting block 412, the connecting block 412 is provided with a threading hole, and the pulling rope 430 is connected to the connecting block 412. One end of the adjusting block 410 close to the strip-shaped through hole 310 is provided with a flip 413, and the inner side of the flip 413 is provided with teeth. The cover 413 is detachably attached to the adjusting block 410 by a screw. The flip 413 and the screw constitute a second connection portion.

Meanwhile, the adjusting block 410 can restrict the balancing weight 420, so that the whole balancing weight is prevented from shaking randomly to cause the textile belt 500 to roll randomly, the textile belt 500 can be in a tight state as much as possible, the abrasion efficiency of the polishing wheel 110 is improved, and the time required by testing is shortened.

With reference to fig. 12 to 14, in order to further improve the stability of the test and improve the performance of the adjusting block 410, the adjusting block 410 is configured to be a round cake shape, the width of the groove 331 is slightly larger than the diameter of the adjusting block 410, and the depth of the groove 331 is slightly larger than the thickness of the adjusting block 410. Thus, in the process of swinging the swinging plate 330, the adjusting block 410 can rotate to a certain degree, so that the tension of the textile belt 500 by the balancing weight 420 is more balanced, and the loss of the pulling rope 430 is reduced.
