Electrophoretic coating device with colors convenient to change

Abstract

The invention provides an electrophoretic coating device with colors convenient to change. The electrophoretic coating device with the colors convenient to change comprises a main body, a shell body is arranged in the interior of the main body, a fixed baffle plate and a driving mechanism are arranged in the interior of the shell body, the front side of the driving mechanism is movably provided with a rotating shaft, the front side of the rotating shaft is fixedly provided with a driving gear, and the driving gear is connected with a movable block in a meshing mode. According to the electrophoretic coating device with the colors convenient to change, power is generated through the driving mechanism, the rotating shaft is used for driving the driving gear to rotate, the driving gear drivesthe movable block through meshing connection, the movable block drives a sliding block to move upwards through a connecting rod, a second baffle plate is driven to move upwards together while the sliding block moves upwards, the second baffle plate is separated from a second feeding pipeline, the electrophoretic liquid of the other color flows to an electrophoretic spray head through the second feeding pipeline and is sprayed out from the electrophoretic spray head, and electrophoretic coating process treatment is carried out on a workpiece, so that the device achieves the effect of realizingconversion of electrophoretic colors.

Description

technical field [0001] The invention belongs to the technical field of electrophoretic coating, and in particular relates to an electrophoretic coating device which is convenient for changing colors. Background technique [0002] Electrophoretic coating is a coating method that uses an external electric field to make the particles such as pigments and resins suspended in the electrophoretic liquid directional migrate and deposit on the substrate surface of one of the electrodes. The principle of electrophoretic coating was invented in the late 1930s, but it was developed This technology was applied in industry after 1963. Electrophoretic coating is a special coating film formation method developed in the past 30 years. It is the most practical construction process for water-based coatings. It is water-soluble, non-toxic, Easy automatic control and other characteristics, it has been widely used in industries such as automobiles, building materials, hardware, and home applianc...

Problems solved by technology

[0003] The electrophoretic coating process generally consists of four main processes: pretreatment before coating, electrophoretic coating, cleaning after electrophoresis, and drying of the electrophoretic coating film. However, in the existing electrophoretic process, it is difficult to do To change the color, only one color can be used for electrophoresis, which is difficult to meet the needs of users. In addition, the traditional equipment is usually fixed in one direction during the fixing process. This kind of fixing effect is not ideal. Instability, and the traditional equipment has complex structure, high energy consumption, and high use limitations
