[0024] In this embodiment, the entire device is installed in the corresponding position. The stripping roller 101 is located diagonally above the cathode roller for producing lithium-ion copper foil. After the copper foil is formed on the surface of the cathode roller, the copper foil is pulled onto the stripping roller 101 to strip the copper foil, and then the copper foil is led to the cutting knife roller 102 for edge trimming. Before edge trimming, according to the actual production requirements of the lithium-ion copper foil, the controller is used to start the moving mechanism to adjust the horizontal use position of the cutting mechanism, so as to adjust the horizontal use position of the cutting mechanism relative to the cutting knife roller 102, and thus the cutting width of the lithium-ion copper foil can be adjusted.
