Description

Technical Field

[0001] This utility model relates to the technical field of board material testing devices, specifically, to a device for testing the scratch resistance of surface coatings on furniture boards. Background Technology

[0002] As a mainstream product in the modern furniture industry, panel furniture typically requires a protective coating to be sprayed onto the surface of the panels during the production and processing process. This significantly improves the wear resistance, corrosion resistance, aging resistance, and scratch resistance of the furniture surface, extends its service life, and ensures its appearance quality.

[0003] To accurately assess the scratch resistance of furniture board surface coatings and ensure that the quality of finished products meets standards, existing technologies generally employ a dedicated testing device equipped with a scratch head to conduct scratch resistance tests on the board coatings. By having the scratch head contact the coating surface and apply force, the scratch wear during use is simulated, thereby achieving quantitative testing and quality control of the board's scratch resistance performance.

[0004] However, existing devices generally adopt a fixed arrangement for vertical scraping, and the scraping head can only perform scraping tests on the board surface along a single angle and a single direction. Since in actual use, the scratches on the furniture surface are mostly random scratches at multiple angles, oblique directions, and non-vertical directions, the test results cannot fully reflect the actual scratch resistance of the board coating in daily use, thus affecting the comprehensiveness of the test data.

[0005] Therefore, those skilled in the art provide a scratch resistance testing device for surface coatings of furniture boards to solve the problems mentioned in the background art. Utility Model Content

[0030] Working principle: The operator first places the plate body 9 into the fixing seat 8 on top of the mounting plate 7 for initial positioning. The anti-slip pad 19 inside the fixing seat 8 prevents the plate from slipping, thus ensuring the stability of the testing benchmark. The corresponding scraping head 25 is selected according to the test standard. The replacement head 26 is inserted into the fixing block 24, and the screw 28 is screwed in to lock the third threaded hole 27, completing the quick replacement of the scraping head 25. The threaded rod 14 is pulled, causing the arc-shaped block 20, along with the limiting block 31, to slide along the arc-shaped groove 23 and the limiting groove 29 of the semi-circular plate 11. The scraping angle is adjusted in conjunction with the rotating shaft 12 to align with the first... After screwing in the first threaded hole 22 and the second threaded hole 30, the bolt 21 is locked at the angle; rotating the threaded rod 14 can drive the scraping head 25 to rise and fall, precisely adjust the contact pressure, start the motor 2 to drive the lead screw 6 to rotate, the connecting block 16 cooperates with the slider 15 and the slide groove 4 to guide, drive the mounting plate 7 and the plate body 9 to feed longitudinally, complete the longitudinal scratch test of the coating, after single-point test, start the hydraulic cylinder 10, the square block 18 slides along the transverse groove 17, drive the fixed seat 8 to move laterally, switch the test point, realize the full coverage test of the plate, and comprehensively test the scratch resistance performance of the coating.
