Description

Technical Field

[0001] This utility model relates to the field of quantitative supply technology, specifically a quantitative supply device. Background Technology

[0002] In the production of elastic abrasive blocks, the use of polishing slurry is a crucial step. Polishing slurry not only helps improve the surface finish of the abrasive blocks but also enhances their performance and lifespan. Polishing slurry typically contains a variety of components such as abrasives, dispersants, and surfactants. In the production of elastic abrasive blocks, polishing slurry suitable for polishing elastic materials such as polyurethane should be selected to ensure the smoothness and finish of the abrasive block surface. The polishing slurry is evenly applied to the surface of the elastic abrasive block, and then polishing is performed using polishing equipment (such as polishing machines, grinding machines, etc.). In the production process of elastic abrasive blocks, the quantitative supply of polishing slurry is a key link to ensure polishing quality and production efficiency. However, the existing supply of polishing slurry for elastic abrasive blocks does not have the function of quantitative addition. Excessive addition of polishing slurry can easily lead to an excessively high concentration of polishing slurry, which increases the number of abrasive grains per unit volume. During polishing, abrasive grains are prone to accumulation and agglomeration, resulting in uneven polishing. Utility Model Content
