Description

Technical Field

[0001] The invention belongs to the technical field of viscosity detection, in particular to a coating viscosity detection and adjustment device. Background Art

[0002] Paint viscosity is an important parameter in the paint production process, which directly affects the paint's construction performance and the quality of the final coating. At present, paint manufacturers generally use viscometers for viscosity testing. However, due to the wide variety of paints, the viscosity ranges of different paints vary greatly, and different specifications of utensils are required during the testing process. As a result, traditional viscosity testing equipment has obvious deficiencies in versatility and adaptability. In recent years, with the rapid development of the paint industry, higher requirements have been placed on the accuracy, efficiency and adaptability of viscosity testing equipment.

[0003] In the existing technology, paint viscosity detection mainly adopts equipment such as rotational viscometer, falling ball viscometer and capillary viscometer. Rotational viscometer calculates viscosity by measuring the resistance of the rotor rotating in the paint, and is suitable for medium and high viscosity paints; falling ball viscometer reflects viscosity by measuring the time it takes for a small ball to fall in the paint, and is suitable for low viscosity paints; capillary viscometer evaluates viscosity by measuring the time it takes for the paint to flow through the capillary. Although these devices can meet basic viscosity detection needs, when facing different specifications of vessels, they often need to replace adapters or adjust the detection position, which is cumbersome and inefficient.

[0004] Due to the lack of height adjustment function, when facing utensils of different specifications, it is necessary to frequently replace the adapter or adjust the position of the equipment, which not only increases the complexity of operation, but may also lead to increased detection errors. In addition, the adjustment process of existing equipment usually relies on manual operation, which is difficult to achieve fast and accurate adjustment, affecting the detection efficiency and the reliability of the results. It is necessary to improve the detection efficiency by quickly adjusting the height of the sample to be tested. Summary of the Invention
