Description

Technical Field

[0001] This utility model relates to the field of foil production technology, and more specifically, to an aluminum foil winding device. Background Technology

[0002] In aluminum foil production, pressure rollers and guide rollers play a particularly important role, especially in the winding, slitting, and subsequent processing of aluminum foil. They primarily control the gaps between aluminum foil layers by applying pressure, eliminating air pockets between layers to ensure the flatness and tightness of the rolled aluminum foil. Appropriate pressure from the pressure rollers helps improve the flatness of the aluminum foil and reduce defects such as wrinkles on the surface.

[0003] In summary, the pressure rollers have a significant impact on the interlayer gap of aluminum foil. By properly adjusting the pressure and uniformity of the face pressure rollers, it is possible to ensure that the aluminum foil maintains flatness and tightness during the winding process, thereby improving the overall quality of the aluminum foil.

[0004] Traditional aluminum coil aluminum foil production using pressure rollers involves controlling the rollers by applying force to a support arm using hydraulic or pneumatic cylinders. The support arm then transmits force to the pressure roller via leverage, pressing it against the aluminum foil surface. Driving this large support arm requires overcoming significant rotational inertia. This can lead to issues such as the aluminum coil not being perfectly round, causing impacts on the aluminum foil, incomplete air removal, and deformation of the foil after annealing due to interlayer air and compression.

[0005] The existing foil rolling technology suffers from foil deformation during rolling. Therefore, designing a device that can flexibly adjust the rolling process is a technical problem that urgently needs to be solved in this field. Utility Model Content
