Description

Technical Field

[0001] This utility model relates to the field of stirring devices, and in particular to a cathodic electrophoretic paint adding and stirring device. Background Technology

[0002] Electrophoresis is one of the most effective methods for coating metal workpieces. Electrophoretic paint, also known as electrophoretic coating, is used by placing the workpiece as an electrode in a paint tank diluted with water. The paint particles are charged and deposited on the workpiece surface by using an electric field. Before use, due to the sealed storage in the container, some components will precipitate and separate. At the same time, in order to reduce the viscosity of the electrophoretic paint and improve its adhesion, some liquid raw materials need to be added for mixing.

[0003] After prolonged storage, some raw materials in electrophoretic paint may precipitate and crystallize during stirring, making the paint viscous and difficult to stir directly. If all the diluent or other liquid raw materials are added directly, the liquid raw materials and electrophoretic paint are prone to separation. During stirring, the contact area between the liquid raw materials and the electrophoretic paint is small, which leads to insufficient stirring and uneven mixing of raw materials, affecting subsequent electrophoresis work. Therefore, a cathodic electrophoretic paint adding and stirring device is needed to solve the above problems. Utility Model Content

Since the capacity of sleeve 25 is fixed, the user can add a certain amount of liquid according to the number of presses and the pressing depth.
