Soaking type automatic metal zipper gold plating apparatus

Abstract

The present invention discloses a soaking type automatic metal zipper gold plating apparatus, which comprises a cavity (1), a belt entering device (2), a belt exiting device (3), a liquid discharge port (4), a gold plating liquid (6) arranged inside the cavity (1) and a cooling pipe (5) arranged inside the cavity (1), and is characterized in that the belt entering and exiting manner of the single zipper in the cavity (1) is the one entering-one exiting manner under effects of the belt entering device (2) the belt exiting device (3). The invention relates to the field of zipper manufacturing.

Description

[0001] Technical field [0002] The invention relates to the field of zipper manufacturing, in particular to a immersion type metal zipper automatic gold plating device. Background technique [0003] Metal zippers are mostly used on high-end bags and clothes. The surface of the metal zippers needs to be polished and then gold-plated or painted. Chemical gold plating is a kind of metal zipper surface treatment. It uses the principle of chemical reaction to remove the metal in the gold plating solution. The ions are transferred to the tooth head surface of the metal zipper, thereby changing the surface color of the metal zipper and protecting the surface of the metal zipper to reduce the influence of oxidation on the zipper. In actual production, in order to improve work efficiency, most zipper gilding machines are The automatic gilding machine is adopted, and the automatic gilding machine uses multiple upper and lower belt wheels to make the zipper move continuously in the gold...

AI Technical Summary

Problems solved by technology

[0004] The problem with the automatic gold plating machine mentioned in the background technology is that since the gold plating solution is composed of strong acidic and oxidizing substances such as hydrogen peroxide, sulfuric acid, and nitric acid, when the zipper leaves the gold plating solution, there will be residual liquid of the gold plating solution on the zipper , when the thin gold-plating solution encounters air, it will volatilize, and the naked eye will see that the zipper will emit white mist at the place where it leaves the gold-plating solution. Because the traditional automatic gold-plating machine uses the zipper to move continuously and repeatedly enter and exit. Gold plating is carried out by means of a zipper. To complete the gold plating of a zipper, it must be repeatedly entered and exited by the gold plating solution for many times. It cannot work continuously for a long time, otherwise a large amount of acidic white mist will be volatilized, which will not only waste the gold plating solution, but also cause great harm to the human body and serious pollution to the environment, but the automatic gold plating machine that cannot work for a long time It has caused the disadvantages of low efficiency, low degree of automation and high production cost, which cannot meet the needs of actual production.
