Barrel plating device for hardware used in cooperation with barrel plating device and working method thereof

Abstract

The invention discloses a barrel plating device for hardware used in cooperation with the barrel plating device. The barrel plating device comprises an electroplating bath, a roller located in the electroplating bath, a power source used for powering on electroplating liquid in the electroplating bath and a driving part used for driving the roller; an insulated second roller is arranged in the roller, the axis of the roller is parallel to the axis of the second roller, and a main body part of the second roller is of a grid hollowed-out structure; the second roller is fixed to the lower half side of the roller through a suspension arm assembly, and a second electroplating part in the second roller is communicated with a first electroplating part in the roller through an electric wire; and the second roller is provided with an end cover with at least one side capable of being opened, and the suspension arm assembly is made of insulating materials. According to the barrel plating device for the hardware used in cooperation with the barrel plating device provided by the invention, through the arrangement of the internal roller and the self-driven second roller, the rollers are independent according to the rolling efficiency requirements of to-be-plated parts of different sizes, and therefore the parts of each size have the good internal and external rolling efficiency in the same electroplating environment.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a barrel plating device used for supporting hardware and a working method thereof. Background technique [0002] The supporting hardware includes small-sized hardware such as buttons, zippers, trouser hooks, and belt buckles. The electroplating is often achieved by barrel plating. The existing barrel plating includes horizontal barrel plating, inclined barrel plating and vibrating barrel plating. plating. [0003] like figure 1 As shown, the horizontal barrel plating equipment includes a cylinder 1 arranged in an electroplating tank, and a cathode conductor 111 is arranged in the cylinder 1. The cathode conductor is often a copper wire coated with an insulating layer, and one end has a conductive terminal and is connected to the The electroplating parts are in contact, and the cylinder 1 is provided with a diversion hole for convection of the electroplating solution. The anode 112...

Problems solved by technology

[0004] At present, the electroplating of matching hardware often adopts horizontal barrel plating, because the matching hardware often has different sizes and quantities, for example, the matching zipper includes zipper puller and zipper element, and the size of the chain element is larger than that of the zipper puller. The size is small, but the number of chain teeth is more than that of the zipper puller. If they are mixed and placed in the drum, the number of plating is different due to the different sizes. On the one hand, the stacking density of the hardware to be plated in the drum is different, such as figure 2 As shown, the volume of the zipper pullers 12 in the drum 1 is large but the number is small, and the volume of the fastener elements 13 is small but the number is large, so that the zipper pullers with a small number but a large volume tend to be trapped for a long time during electroplating and tumbling. The inside of the chain elements 13 with a large number of small volumes is electrostatically shielded, and the zipper puller 12 cannot obtain better rolling efficiency, so that the electroplating effect of the zipper puller 12 is poor

That is, the difference in current density flowing through the surface of each electroplating part will lead to the difference in plating thickness and electroplating effect. On the other hand, when the hardware parts to be electroplated with different sizes are tumbling with the drum synchronously, the hardware parts to be electroplated with different sizes cannot be alternated inside and outside synchronously. Tumbling, resulting in a large difference in plating effect

Moreover, it is also time-consuming and labor-intensive to separate the hardware after mixing and placing and electroplating

In addition, separate electroplating of hardware parts of different sizes through two processes will lead to differences in the electroplating environment such as the concentration of the electroplating solution, resulting in differences in the electroplating of the supporting hardware parts, and at the same time reducing the electroplating efficiency
