Detailed Implementation

[0016] like Figs. 1-2 As shown, a rubber abrasion resistance testing machine with good cleaning effect includes a testing platform 1, a clamping platform 2, a grinding roller 3, and a clamping platform drive device 4. The grinding roller is set on the testing platform and rotatably connected to the testing platform. The clamping platform drive device is set above the grinding roller. The clamping platform is set on the clamping platform drive device. The clamping platform is provided with a clamping groove for mounting rubber samples. The testing platform is provided with a grinding roller cleaning device 5. The grinding roller cleaning device includes a protective cover 6, a mounting shaft 7, several cleaning brushes 8, and a switch drive motor 9. One side of the protective cover is rotatably connected to the testing platform. The mounting shaft is set on the protective cover and rotatably connected to the protective cover. The several cleaning brushes are fixedly set on the mounting shaft. The switch drive motor is set on the top of the protective cover and connected to the mounting shaft.

[0017] The grinding roller cleaning device, which includes a protective cover, mounting shaft, several cleaning brushes, and a switch drive motor, is set up so that after the abrasion testing machine is started, the switch drive motor is activated, driving the mounting shaft to rotate at a certain angle. This causes the cleaning brushes to simultaneously adhere to the grinding roller and clean its surface. Even as the clamping table continues to move, the cleaning brushes can also clean the surfaces that were previously in contact with the sample until the grinding roller surface is completely cleaned. After cleaning, the switch drive motor rotates again, causing the mounting shaft to reset. The cleaning brushes then leave the surface of the grinding roller, and the debris accumulated on the brush heads falls off. At the same time, the protective cover effectively prevents the debris from splashing. When the brushes need to be replaced, simply flip the protective cover downwards.

[0018] An active switch lever 10 is connected to the rotating shaft of the switch drive motor, and a driven lever 11 is fixedly provided at one end of the mounting shaft. The active switch lever is in contact with the driven lever.

[0019] The switch driving motor is connected with a driving switch lever on the rotating shaft, one end of the installation shaft is fixed with a driven lever, the driving switch lever contacts with the driven lever, the switch driving motor drives the switch lever to rotate, and then drives the driven lever to rotate to rotate the installation shaft.

[0020] The installation shaft is provided with a plurality of clamping grooves 12 for installing the cleaning brushes, and the plurality of cleaning brushes are detachably arranged in the clamping grooves.

[0021] The installation shaft is provided with a plurality of clamping grooves for installing the cleaning brushes, and the plurality of cleaning brushes are detachably arranged in the clamping grooves, so that the cleaning brushes can be replaced individually according to actual conditions.

[0022] The test machine is provided with a dust baffle 13 at a position below the grinding roller.

[0023] The test machine is provided with a dust baffle at a position below the grinding roller, so that the debris can be further prevented from splashing.

[0024] The test machine is provided with a debris collecting groove 14 at a position below the plurality of cleaning brushes.

[0025] The test machine is provided with a debris collecting groove at a position below the plurality of cleaning brushes, so that the debris brushed off from the surface of the grinding roller can fall into the debris collecting groove, and the debris collecting groove only needs to be taken out and cleaned periodically.
