Description

Technical Field

[0001] The utility model relates to the technical field of adhesion measuring instruments, in particular to a jewelry paint film adhesion measuring instrument. Background Art

[0002] In jewelry craftsmanship, a paint film needs to be attached to the outer layer of the metal. In order to improve the durability of lacquer jewelry products, it is necessary to measure the combination of various different paint materials and various metals, and simulate the scratches caused by collisions during the wearing of lacquer jewelry. Therefore, an adhesion tester is needed to measure the adhesion of the jewelry paint film. In order to simulate the scratches caused by the actual situation of jewelry, the jewelry paint film is applied to the metal plate used to make the jewelry, and then fixed on a base that can move back and forth. The base then moves in a circle while moving, causing scratches on the paint film plate. The adhesion of the paint film is measured by evaluating the integrity of the paint film within the scratch range.

[0003] However, jewelry materials such as gold and silver have a certain degree of stretchability, and their thickness is relatively thin and easily deformed. When fixing after the paint film is applied, it can only be fixed on all sides without stretching the paint film plate. Since the material is relatively soft, it is easily pulled by the force of scratches and deformed when fixed, which in turn affects the integrity of the sliding of the paint film and easily causes deviations in the measurement of the paint film adhesion. In addition, the height and position of the rotating needle are fixed, which easily causes the strength and tightness of the circular motion to be limited. The adhesion state of the paint film under different scratch strengths cannot be measured, and the adhesion of the paint film under a state of dense scratches cannot be measured. The simulation of jewelry wearing is not comprehensive enough. Utility Model Content
