A barrel plating device for clothing hardware and its working method

Abstract

The invention discloses a barrel plating device for clothing hardware. An insulating second roller is arranged inside the roller. The axis lines of the roller and the second roller are parallel, and the main body of the second roller has a grid hollow structure; The second drum is fixed on the lower half of the drum through the boom assembly, the wall of the second drum is provided with stirring blades, and the telescopic arm is set so that the stirring blades can contact the first electroplating parts in the drum by stretching and contracting the length, stirring The blade is set to be able to be pushed by the first electroplating part that rolls with the rotation of the drum, and the stirring blade is provided with an electric wire coated with insulating material and conductive at both ends. The invention discloses a barrel plating for clothing hardware The device rolls parts to be plated of different sizes separately by setting internal rollers, so that parts of each size have better internal and external tumbling efficiency.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a barrel plating device for clothing hardware and a working method thereof. Background technique [0002] Clothing 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 vibration barrel plating. [0003] Such as 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 of the power supply...

AI Technical Summary

Problems solved by technology

[0004] At present, the electroplating of clothing hardware often adopts horizontal barrel plating, because the matching clothing hardware often has different sizes and quantities. 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 electroplating is different due to different sizes. On the one hand, the stacking density of the hardware to be electroplated 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
