A dipping automatic gold-plating device for metal zippers

Abstract

The invention discloses an automatic soaking gold plating device of a metal zipper and relates to the field of zipper manufacture. The gold plating device comprises a cavity (1), a feed device (2), a discharge device (3), a liquid outlet (4), as well as gold plating liquid (6) and a cooling pipe (5) that are arranged in the cavity (1). The gold plating device is characterized in that the single zipper in the cavity (1) passes in and out in a one-inlet and one-outlet manner by the action of the feed device (2) and the discharge device (3).

Description

technical field [0001] The invention relates to the field of zipper manufacturing, in particular to a submerged automatic gold-plating device for metal zippers. Background technique [0002] Metal zippers are mostly used on high-end bags and clothes. During production, the surface needs to be polished and then gold-plated or painted. Electroless gold-plating is a kind of surface treatment of metal zippers. The ions are transferred to the surface of the teeth of the metal zipper, thereby changing the surface color of the metal zipper and protecting the surface of the metal zipper to reduce the impact of oxidation on the zipper. In actual production, in order to improve work efficiency, most zipper gold plating machines are The automatic gold plating machine is adopted, and the automatic gold plating machine is made of multiple upper pulleys and lower pulleys to make the zipper repeatedly move continuously in the gold plating solution and repeatedly enter and exit to achieve t...

AI Technical Summary

Problems solved by technology

[0003] 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.
