Abstract

The invention relates to a soft conductive structure inside a cathode roll of a crude foil engine and a manufacturing method thereof. The structure comprises a conductive belt (4), a conductive sleeve (3), a titanium ring (6), a conductive copper ring (2), a sleeve flange (7) and connector sleeves (10). The conductive belt (4) is intertwined with pure copper threads and has connector sleeves at both ends. Through the connector sleeves, both ends of the conductive belt are respectively and fixedly connected with the titanium ring (6) and the sleeve flange (7). The surfaces of both the conductive belt (4) and the connector sleeves (10) are plated with silver or stannum. In this invention, the conductive belt is intertwined with pure copper threads, thereby the soft connection between the conductive sleeve and the surface of the cathode roll is realized, the conductivity of the conductive belt is strengthened and the conductivity uniformity of the surface of the cathode roll is improved. The soft conductive structure also overcomes the deficiency of distortions caused by vibration and thermal inflation of the conductive belt and the movability of the connecting parts, and improves the conductive efficiency and current carrying capacity. The soft conductive structure is characterized by the stable connection, convenient maintenance and processing, simple operation and high production efficiency.

Description

1. Technical field [0001] The invention relates to the copper foil manufacturing industry, in particular to a soft conductive structure inside a cathode roll of a foil machine and a manufacturing method thereof. 2. Technical Background [0002] With the rapid development of the electronics industry, the demand for high-quality copper foil is also increasing. At present, the method of producing copper foil at home and abroad generally adopts the electrolysis method, and the cathode roller is the core equipment for the production of copper foil by the electrolysis method. The cathode roller is a titanium cathode roller body, which has very stable acid resistance and is easy to peel off the electrolytic copper foil after electrolysis. The structure of the cathode roller is mainly composed of a main shaft, a conductive copper ring, a conductive bushing, a conductive belt, an end plate and a titanium cylinder. During use, the cathode roller is immersed in the electrolyte, and th...
