Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil rolling mills, and particularly relates to an oil baffle device for a working roll of an aluminum foil rolling mill. Background Technique

[0002] An aluminum foil rolling mill is a mechanical device that rolls relatively thick aluminum sheet strips through several passes to make them into ultra-thin aluminum foils. Due to the rolling force between the rolling rolls of the aluminum foil rolling mill and the sheet material, aluminum powder dust will fall off. Therefore, rolling oil needs to be used to wash the sheet material. During the washing process of the rolling oil, since the working roll is in a high-speed rotating state, the ejected rolling oil will be washed to the neck part of the working roll. The high-speed centrifugal force of the working roll will throw the rolling oil out from the neck part of the working roll. With the action of the primary blowing, the rolling oil will be blown into scattered oil spots and fall on the aluminum foil surface. Subsequently, due to the extrusion of the wrapping angle roll and the flattening roll, quality problems such as oil on the aluminum foil surface and black oil spots are likely to occur on the aluminum foil surface. Summary of the Invention
