Technical Field
[0001] The utility model relates to the technical field of copper foil processing equipment, in particular to a simple foil surface drying device. Background Art
[0002] According to the production needs of copper foil, copper foil of different thicknesses is attached to the cathode roller by electrolytic deposition of copper sulfate. After the stripping roller strips the copper foil, the copper foil will pass through the wind knife device to dry the moisture on the foil surface, and then be pulled to the winding roller along with multiple guide rollers. However, this production process will be affected by factors such as the angle of the wind knife device, air volume and temperature, resulting in excessive humidity at the edges of foils of different thicknesses. The moisture in the foil cannot dissipate after it is wrapped, and long-term contact with the air causes rapid oxidation of the foil surface. Utility Model Content
