[0020] Beneficial effects of the utility model:

[0021] 1. By setting up a support mechanism, when the fabric body is fixed to the test plate via a third bolt, the second cylinder of the downward pressure mechanism pushes the lifting block downward. The compressed spring generates elastic support force, causing the lifting block to slide along the guide rod and adapt to changes in fabric thickness.

At the same time, the two ends of the mounting rod of the friction mechanism are abutted and limited by the threaded cylinder to prevent axial movement. The second servo motor of the driving mechanism drives the gear and the gear ring to mesh, ensuring the stability of the grinding drum during rotational friction and significantly improving the reciprocating motion accuracy.

[0023] 3. The first servo motor drives the screw to adjust the height of the lifting plate, driving the pressure sensor and rubber block to press the grinding cylinder, which can accurately control the friction pressure. The L-shaped block and the limit block form axial limit for the grinding cylinder to avoid tilting or offset. Combined with the controller and display, the pressure value and friction times can be displayed in real time, realizing the automation of the detection process and data visualization, solving the problems of inconvenient pressure adjustment and poor movement stability of traditional devices.

[0045] See also Figure 1 and Figure 6 In this embodiment, the pressing mechanism 9 includes a bracket 91 and a second cylinder 92. The bracket 91 is fixed to the upper end of the detection platform 1, and the second cylinder 92 is fixed to the bracket 91. The lower end of the output end of the second cylinder 92 extends into the groove 55 of the lifting block 54 and slides against the inner wall of the groove 55. The groove 55 of the lifting block 54 is pushed downward by the second cylinder 92, driving the spring 52 in the support mechanism 5 to be compressed, so that the lifting block 54 elastically descends along the guide rod 53, thereby realizing automatic adjustment of the height of the grinding drum 7, and can quickly adapt to fabrics of different thicknesses without manual operation.

[0046] See also Figure 1 and Figure 7In this embodiment, the upper end of the testing platform 1 is fixedly connected to a vertical block 16, and the upper end of the vertical block 16 is fixedly connected to a first servo motor 18.

The end of the second bolt 64 passes through the gear ring 63 and is threadedly connected to the side wall of the lifting block 54 to fix the relative position of the gear ring 63 and the lifting block 54. When the driving mechanism is not in use, the gear ring 63 is fixed to the side wall of the lifting block 54 by the second bolt 64, so that the mounting rod 61 can be fixed.

[0048] See also Figure 1 and Figure 7 In this embodiment, an L-shaped block 22 is fixedly connected to the lower end of the lifting plate 21, and two limit blocks 23 are fixedly connected to the end of the L-shaped block 22 close to the grinding cylinder 7. The opposite inner walls of the two limit blocks 23 are respectively abutted against the outer walls at both ends of the grinding cylinder 7 to form an axial limit structure. The limit blocks 23 abut against the outer walls at both ends of the grinding cylinder 7, which can limit the grinding cylinder 7, effectively preventing the grinding cylinder 7 from moving or tilting during high-speed rotation, improving the overall stability of the friction mechanism 6, and avoiding detection errors caused by the position offset of the grinding cylinder 7.

[0049] Example 2: Please refer to Figure 1 and Figure 8Based on Example 1, the present application provides a technical solution: the driving mechanism includes a second servo motor 27 and a gear 28, wherein the side wall of one lifting block 54 is fixedly connected to a support 26, and the second servo motor 27 is mounted on the support 26. The output end of the second servo motor 27 is fixedly connected to the gear 28, and the gear 28 is meshed with the gear ring 63 for transmission. The second servo motor 27 drives the gear 28 to mesh with the gear ring 63, and stably transmits the rotational power of the second servo motor 27 to the mounting rod 61 and the grinding cylinder 7, ensuring that the rotation speed of the grinding cylinder 7 is uniform when rotating at high speed.

[0050] Working Principle: When in use, first lay the fabric body 12 flat on the upper end of the test plate 3 so that both sides of the fabric cover the two ends of the test plate 3. Then, pass the third bolt 13 from the lower end of the test plate 3 upward through the fabric body 12 and thread it to the test plate 3 to achieve rapid fixing of the fabric.

[0051] The height of the grinding cylinder 7 is adjusted according to the thickness of the fabric body 12. If the fabric is thicker, the upper end of the fabric will naturally fit in with the lower end of the grinding cylinder 7. If the fabric is thinner, the second cylinder 92 of the pressing mechanism 9 is started, and its output end extends downward into the groove 55 of the lifting block 54, pushing the lifting block 54 downward along the guide rod 53, compressing the spring 52, and driving the grinding cylinder 7 to descend until it fits in with the upper end of the fabric, thereby realizing automatic adjustment of the height of the grinding cylinder 7;

[0052] During testing, two friction modes can be selected:

[0053] The first is a reciprocating linear friction mode: the first cylinder 82 of the pushing mechanism 8 is turned on, and its output end is engaged with the T-slot 15 of the fixing block 14 on the test plate 3 through the fixing plate 83 to limit the position, driving the test plate 3 to slide back and forth along the guide block 201 and the sliding block 202 of the sliding guide mechanism 2, so that the fabric body 12 moves with the test plate 3 and continuously rubs against the surface of the grinding cylinder 7;

[0054] The second mode is rolling friction mode: the test plate 3 is fixed to the test table 1 by the first bolt 4, and the second servo motor 27 of the driving mechanism is started. The gear 28 at its output end is engaged with the gear ring 63, driving the mounting rod 61 and the grinding cylinder 7 to rotate, thereby achieving rolling friction between the grinding cylinder 7 and the fabric body 12;

[0055] During the detection process, the first servo motor 18 drives the screw 19 to rotate, causing the threaded sleeve 20 to slide in the limiting groove 17, adjusting the height of the lifting plate 21, and fine-tuning the contact pressure between the pressure sensor 25 and the grinding cylinder 7 through the fourth bolt 24. The pressure sensor 25 monitors the friction pressure in real time and provides feedback through the display screen 11;

[0056] The limit blocks 23 on the L-shaped block 22 abut against both ends of the grinding cylinder 7, and cooperate with the threaded cylinders 62 at both ends of the mounting rod 61 to abut against the cylinder to prevent the grinding cylinder 7 from axial movement or tilting;

[0057] When the driving mechanism is not in use, the gear ring 63 and the lifting block 54 are fixed by the second bolt 64 to ensure that the grinding cylinder 7 is in a stable position;

[0058] During the entire process, the controller 10 synchronously collects data such as the number of friction times and pressure values. After the detection is completed, the wear resistance is evaluated based on the damage of the fabric surface, realizing an automated detection process from fabric fixation, height adjustment, friction detection to data feedback, taking into account the adaptability of fabrics of different thicknesses and the diversity of detection modes, and is more convenient to use.
