Description

Technical Field

[0001] The utility model relates to the technical field of coating testing equipment, in particular to equipment for testing the surface adhesion of a coating. Background Art

[0002] Coating adhesion is an important indicator for evaluating coating quality and is the basic prerequisite for ensuring that the coating meets various performance requirements. Using the circle method to test coating adhesion is a relatively common measurement method, which requires the use of a paint adhesion tester.

[0018] See attached figure Figure 1 to Figure 2 In this embodiment, a device for testing the surface adhesion of a coating includes a base 1, on which four sets of fixed platforms 2 are arranged, and a placing plate 3 is arranged between two adjacent fixed platforms 2 in front and behind; a fixed structure is arranged on the fixed platform 2; the base 1 is also provided with a bracket 4, on which an electric hydraulic cylinder 5 is arranged, and the output end of the electric hydraulic cylinder 5 is provided with a piston rod 50, and the bottom of the piston rod 50 is provided with a rotating motor 6, and the output end of the rotating motor 6 is provided with a turntable 60, and the turntable 60 is provided with a scraper 61.

[0019] Furthermore, the fixing structure includes an installation cavity 20 arranged in the fixing platform 2, and a first sleeve is arranged in the installation cavity 20, and the first sleeve is composed of four limit blocks 21 of a petal-shaped structure, and the top edge of the limit block 21 is provided with a first conical surface 210; a second sleeve 22 is arranged above the first sleeve, and a second conical surface 221 is arranged at the bottom edge of the second sleeve 22, and the first conical surface 210 and the second conical surface 221 are in conflict with each other; a pressure plate 8 is arranged above the second sleeve 22.
