Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and more specifically, to a detection device for the adhesion of metal powder coatings. Background Technique

[0002] Metal powder coatings refer to various powder coatings containing metal pigments. In the manufacturing process, the dry mixing method is mainly used in the domestic market, while the bonding and fixing method is also used internationally. Both methods can evenly mix the metal pigments with other components of the powder coating to form a coating with excellent performance.

[0003] Metal powder coatings can display bright and luxurious decorative effects and are very suitable for spraying indoor and outdoor objects such as furniture, ornaments, and automobiles. After the existing metal powder coatings are sprayed, it is necessary to manually detect the adhesion effect of the coatings. The commonly used detection method is the grid cutter detection method: a grid pattern with a certain depth is drawn on the surface of the coating, and the adhesion of the coating is evaluated by observing the peeling of the coating at the intersections of the grids. Manual operation cannot ensure consistent detection depth, and it is not convenient to compare for the detection of multiple coatings, and the detection effects cannot be visually compared. In view of this, we propose a detection device for the adhesion of metal powder coatings. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a detection device for the adhesion of metal powder coatings to solve the technical problems of inconsistent grid cutting depth in current manual operations and inconvenience in comparing multiple coatings.

When the detection plate moves into the positioning frame, the sliding cutter on the cross cutter damages the sprayed part on the detection plate during the moving process to form a grid. Five grooves are provided on the outer side of the cross cutter, and a sliding cutter is provided in each groove. After a single processing is completed, there is residual coating at the cutting edge part of the corresponding sliding cutter. Therefore, it is easy to affect the quality of the cross cutting and the judgment during the next processing.
