Technical Field

[0001] The utility model belongs to the technical field of coating abrasion resistance performance testing, in particular to a coating abrasion resistance performance testing device. Background Art

[0002] The coating abrasion resistance test is a test method to evaluate the durability and wear resistance of the coating surface when subjected to external forces such as friction, scratching or abrasion.

[0003] For example, the Chinese patent with publication number CN219830686U discloses a coating wipe resistance performance test device, including a device body, a power interface is provided on the back of the device body, a control box is installed on the front edge of the left top of the device body, a display screen and a controller panel are embedded and installed on the front of the control box from top to bottom, an electric lifting rod is embedded and installed on the front edge of the right top of the device body, a lifting test platform is installed on the top of the electric lifting rod, and clamps are installed on both sides of the top of the lifting test platform. The overall device structure is simple, which is convenient for fixing and adjusting the flat plate of the coating to be tested to perform a stable positioning test on the coating wipe resistance performance. At the same time, it is convenient to monitor and control the wiping speed and strength as well as to monitor and shoot, observe and calculate how many times the coating is wiped clean, so as to accurately test the coating's ability to resist wipes, and it has high stability and practicality, and has certain promotion value.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when this device is used, in the process of testing the coating, wiping debris will be generated, and the fallen debris will remain on the plate, and the remaining debris will cover the coating after wiping, so that the personnel cannot clearly observe the wiping effect. In addition, the wiping head will wear out after long-term use, and when the personnel replace it, they need to use various tools, which is troublesome. In view of this, we propose a coating wipe resistance performance test device. Utility Model Content

[0076] Working principle: When in use, first apply the coating to be tested on the surface of the test plate, then place the test plate under the two L-shaped blocks 9 and on the top of the base 1, and then rotate the two threaded rods 10 respectively. Under the action of the threads, the threaded rods 10 will move downward on the L-shaped block 9. The downward movement of the two threaded rods 10 will squeeze the test plate, and the test plate can be squeezed on the top of the base 1, and then rotate the threaded rod 4. Under the action of the threads, the threaded rod 4 moves downward on the circular frame 3. The downward movement of the threaded rod 4 will drive the rectangular plate 5 to move downward, and at the same time, the threaded rod 4 will rotate on the rectangular plate 5. The downward movement of the rectangular plate 5 will drive the two limit rods 8 to move downward. The downward movement of the rectangular plate 5 will also drive the two cleaning brushes 7 and the wiping block 6 to move downward until the bottom of the two cleaning brushes 7 and the wiping block 6 are against. On the coating on the top of the test plate, the motor 18 is then started, and the output shaft of the motor 18 rotates to drive the turntable 14 to rotate in the circular groove 13, and the rotation of the turntable 14 drives the limit block 15 to rotate, and the limit block 15 drives the circular frame 3 to reciprocate in the sliding groove 2 through the movable groove 16, and at the same time, the limit block 15 slides and rotates in the movable groove 16, and the reciprocating motion of the circular frame 3 drives the two cleaning brushes 7 of the wiping block 6 to reciprocate, and the reciprocating motion of the wiping block 6 can wipe the coating on the top surface of the test plate, and the reciprocating motion of the two cleaning brushes 7 can clean the debris dropped during the wiping, and the dropped debris will be swept into the two collecting grooves 11 by the two cleaning brushes 7, and the debris in the collecting groove 11 will fall into the collecting box 12, so that it is convenient for personnel to collect them in a centralized manner, and at the same time, when testing the abrasion resistance of the coating, the debris will not block the sight of the personnel;

[0077] When the wiping block 6 is worn out after long-term use, the personnel can rotate the two-way threaded rod 22. Under the action of the thread, the two-way threaded rod 22 rotates to drive the two sliding blocks 20 to approach each other in the slot 21. When the bottom of the two sliding blocks 20 coincides with the top of the slot 21, the wiping block 6 can be removed and a new wiping block 6 can be placed on the bottom of the rectangular plate 5. When the slot 21 on the wiping block 6 is sleeved on the two sliding blocks 20, the personnel rotates the two-way threaded rod 22 again. Under the action of the thread, the two-way threaded rod 22 rotates to drive the two sliding blocks 20 to move away from each other in the slot 21. When one end of the two sliding blocks 20 rests against the inner wall of the slot 21, the two sliding blocks 20 can limit the wiping block 6, ensuring that when the wiping block 6 is worn, it is convenient for personnel to replace the wiping block 6. At the same time, no tools are required when replacing the wiping block 6, which is convenient for personnel to operate.

[0078] The embodiments of the present application are described above in conjunction with the accompanying drawings.
