Description

Improved aluminum strip splitting machine

Technical Field

The utility model relates to the technical field of aluminum coil slitting equipment.

Background

The aluminum strip is rolled and formed and then wound into a parent roll with wider width so as to be used in various industries. In the new energy battery industry, the shell, the tab and the like of the battery are required to be made of aluminum sheets, so that larger parent rolls are required to be cut into aluminum strips with different widths according to the required size and rewound for subsequent continuous production; moreover, the welding performance of the new energy battery product on the aluminum sheet is very high. The aluminum coil inevitably has slight greasy dirt in the roll forming process, so that the surface tension cannot pass the 38 # dyne pen test, and the welding result is difficult to meet the requirement. The existing method is that the aluminum coil after being cut is put into an annealing furnace to be deoiled at high temperature before being put into use, which not only brings waste of manpower and time cost, but also causes deformation of the coil of the aluminum coil for a plurality of times, thereby influencing the quality of subsequent automatic production.
