secondly, when the working roll 2 is in contact with the aluminum foil, aluminum powder is generated on the aluminum foil due to rolling, because the aluminum foil is charged opposite to the attraction electrode plate 10 through the charge generator 13, the aluminum powder is adsorbed on the outer wall of the working roll 2 by the attraction electrode plate 10, and is repelled when passing through the repulsive electrode plate 1001 under the rotation of the working roll 2, the aluminum powder is transferred to the outer wall of the supporting roll 3, and when the outer wall of the supporting roll 3 carrying the aluminum powder is rotated to the aluminum powder box 301, the aluminum powder falls into the aluminum powder box 301;
finally, in order to continuously adjust the amount of the lubricating oil mist absorbed by the working roll 2, the amount of the residual oil mist on the aluminum foil is measured through the oil suction roll 801, the scraping plate 802 and the flow device 803, and then is transmitted to the residual oil amount detection module 1204, and the result is transmitted to the oil supply amount regulation module 1203 through calculation of the association regulation unit 1202 and the main control unit 1201, so that the voltage of the suction electrode plate 10 is continuously corrected, the amount of the lubricating oil absorbed by the working roll 2 is continuously adjusted, and the lubricating oil is ensured to be completely evaporated after rolling is finished.
