Abstract

The invention provides an electric conducting roller capable of reducing the arcing phenomenon in an electrode foil powerup process. The electric conducting roller comprises a cylinder, and a roller shaft penetrating in the cylinder; bearings are mounted at two ends of the roller shaft; circular end covers are additionally mounted at the left and right ends of the cylinder; the roller shaft penetrates through the centers of the end covers; and an electric conducting bar is fixedly arranged in the axial direction of the outer surface of the cylinder. In the electric conducting roller capable ofreducing the arcing phenomenon in the electrode foil powerup process, through adding of the electric conducting bar on the surface of the cylinder, the current carrying capacity is improved, the heating quantity is reduced, the defect caused by adding of a cooling device is prevented, and the arcing problem in the electrode foil powerup process is reduced.

technical field [0001] The invention belongs to the field of electric conduction technology, and in particular relates to a conduction roller for reducing flashover phenomenon during electrification of electrode foils. Background technique [0002] The electrode foil for aluminum electrolytic capacitors often uses electrolytic technology in the production process (corrosion, chemical conversion process), that is, by applying direct or alternating current to the aluminum foil to perform electrolytic corrosion and drilling in the chemical solution, and then form an oxide film on the surface of the electrode foil. At present, the general practice is to directly contact the aluminum foil with a smooth conductive roller to conduct the current to the aluminum foil.

AI Technical Summary

Problems solved by technology

At present, the general practice is to directly contact the aluminum foil with a smooth conductive roller to conduct the current to the aluminum foil. With the continuous increase in production speed, the current applied to the conductive roller continues to increase. The contact area with the aluminum foil is limited, the conductive effect is not ideal, the heat generated by the contact part of the conductive roller and the aluminum foil is getting larger and larger, and flashover often occurs, and the aluminum foil is easy to deform and wrinkle after being heated, which reduces the product quality. prone to large waste

To solve this problem, the effect is still not ideal by adding an air cooling device or passing cooling water inside the conductive roller, and at the same time it will bring a series of other problems, such as uneven heat dissipation, impurities in the air pollute the surface of the aluminum foil, conductive The surface of the roller is prone to condensate, etc.
