AI Technical Summary
Traditional foil making machines are inconvenient to adjust in terms of electrode spacing control, and the connection and support methods between the cathode roller and surrounding components are not optimized, which affects the uniformity and quality of copper foil thickness.
The design employs an arc plate with screw and nut, allowing for adjustment of the gap between the arc plate, thin-walled side plate, and cathode roller via the screw and nut. This, combined with the tensile deformation of the thin-walled side plate and the flexible hose connection of the overflow groove, enables precise control of the electrode spacing. The semi-coupling between the forward and backward shafts and the cathode roller uses a pin-sleeve connection, simplifying the connection and torque transmission.
It enables precise adjustment of the electrode spacing, ensuring uniform copper foil thickness and high-quality production, simplifies the disassembly and assembly process of the cathode roller, and reduces manufacturing costs.
