Conductive roller

The utility model relates to a conductive roller. The method is used for capacitor aluminum foil production. The conductive roller comprises a conductive roller body, a roller shaft and a flange plate, the conductive roller body is installed on the roller shaft through the flange plate, a cooling water channel is formed in the roller shaft, and the conductive roller is characterized in that the conductive roller body, the roller shaft and the flange plate are made of copper, copper alloy, stainless steel or aluminum, and a silver powder coating is sprayed on the upper surface of the conductiveroller body in a cold mode. Through the cold spraying mode, the combination between the silver powder coating and the surface of the roller is very firm, no gap exists, the thickness of the silver powder layer can be controlled according to actual needs, the manufacturing cost is reduced, the service life is prolonged, and the quality stability of products is improved. 本实用新型涉及一种导电辊，用于电容器铝箔的生产中，包括导电辊筒、辊轴和法兰盘，所述导电辊筒通过所述法兰盘
