Description

Technical Field

[0001] The utility model relates to the technical field of oil spraying before aluminum foil is rolled, in particular to an oil spraying device before aluminum foil is rolled. Background Art

[0002] During the aluminum straightening production process, when the aluminum material is rolled to a certain thickness, it is formed into a plate-shaped aluminum foil. The surface roughness of the aluminum foil is low and its surface is smooth. After the aluminum foil is cleaned, when the plate-shaped aluminum foil is subsequently rolled on a coiling machine, the surface of the aluminum foil strip loses the protection of the oil film after the cleaning process. During the coiling process, it is easy for the layers to rub against each other, causing lateral scratches on the plate surface, affecting the plate surface quality, and easily causing product quality to be unqualified.

[0003] In addition, the existing aluminum foil winding machines often spray oil on the surfaces of the upper and lower aluminum foils, but such operation has the following problems: the oil sprayer that sprays oil on the surface of the upper aluminum foil sprays oil upward, and the scattered oil mist will fall on the surface of the lower aluminum foil, causing the oil film on the surface of the lower aluminum foil to be too thick, which is not conducive to the winding of the aluminum foil; further, the oil mist is adsorbed on the surface of the oil sprayer and gradually condenses into oil droplets, which will fall on the surface of the lower aluminum foil, causing an uneven oil film on the surface of the lower aluminum foil; the oil mist will also scatter to the outside of the winding machine, which not only pollutes the environment but also causes oil loss.
