Description

Technical Field

[0001] The invention relates to the technical field of gloss meters, in particular to an adjustable gloss meter used for measuring the gloss of a curved surface. Background Art

[0002] Gloss meter, also called gloss meter, is an instrument used to measure the surface gloss of materials such as ceramics, paints, inks, plastics, marble, aluminum, and hardware. High-precision gloss meters are divided into three types according to the angle: high gloss, medium gloss, and low gloss. There are two types of gloss meters, one is a smaller handheld type, and the other is a larger seated type. In the paint production process, the gloss of the paint is an important indicator for decorative and corrosion resistance. The gloss of the paint refers to the ability of the paint surface to reflect the light projected on it toward the mirror surface. The greater the reflected light, the higher the gloss.

[0003] In the prior art, a gloss meter is needed to test the gloss of the paint during the paint production process, and in order to improve the accuracy of the test results, the staff generally performs measurements at multiple angles. Before each change of the measurement angle, the staff needs to exit the measurement process and manually select the test angle of the tester before continuing the measurement, which is more troublesome to use. In addition, the traditional angle adjustment device often positions the object to be measured by friction, so its stability is not high and the overall adjustment process is more cumbersome. At the same time, the general sample smear plate is flat. When the sample smear plate is a curved surface, the adjustment device of the flat sample smear plate cannot be well applied, which causes trouble to the measurement. Summary of the invention
