Method and device for colouring metal index tag through electrophoresis

Abstract

The invention discloses an electrophoresis coloring method for metal tag in tag making industry, which comprises: connecting the first electrode with metal tag; arranging the coloring surface of tag upward horizontally; putting the second electrode on the tag upper; pouring the electrophoresis lacquer on metal surface to make second electrode contact with the lacquer; electrifying two electrodes for a period of time. Besides, the device also comprises a working bench with the second electrode on its upper; the second electrode is supported on the electrode frame connected or integrated with the bench. This invention saves mateial with high quality.

Description

technical field [0001] The invention relates to a method for painting and coloring a metal signboard or characters or patterns made on the metal signboard and a coloring device using the method. Background technique [0002] There are many ways to color metal signs, such as spraying, pen holder coloring or electrophoretic paint. Due to the better quality of electrophoretic coloring, it is often used. The existing electrophoretic coloring has been carried out in a swimming tank for a long time, that is, the metal sign electrically connected to the first electrode is dipped in a swimming tank filled with electrophoretic paint, and then the first electrode and the second electrode in the swimming tank The electrodes are energized, so that the electrophoretic paint between the electrodes is coated on the surface to be colored of the metal sign. The amount of electrophoretic paint used in this coloring method is relatively large, and the prepared electrophoretic paint must be u...

AI Technical Summary

Problems solved by technology

The amount of electrophoretic paint used in this coloring method is relatively large, and the prepared electrophoretic paint must be used up in a short time, otherwise it will deteriorate and the coloring quality cannot be guaranteed

However, in the actual production process of the sign making industry, most of the metal signs that require electrophoretic coloring belong to small batches and many varieties. Sometimes the company has work to do, and sometimes it is idle. In this way, it is necessary to change the paint frequently. It is necessary to prepare a swimming tank with electrophoretic paint for one job, and then either need to change the paint or put it aside, resulting in a waste of this swimming tank paint. Therefore, the swimming tank coloring process has a large amount of waste, high coloring costs, and repeated use of the same paint. Swimming tanks also affect the quality of coloring
