[0002] In the existing copper foil production process, after the copper foil comes out of the anti-oxidation process, it needs to be blown dry by the air knife nozzle. In order to control the distance between the copper foil and the air knife nozzle, the operator usually rolls the foam cotton into a small roll, and then uses tape to stick the small roll of foam cotton on the air knife shell above the width of the copper foil to achieve the control of the distance between the copper foil and the air knife nozzle. The above method is not only cumbersome to operate and inefficient, but also has the disadvantage that the distance between the copper foil and the air knife nozzle cannot be adjusted. In addition, there is a quality risk that the foam cotton falls off and adheres to the surface of the copper foil during the copper foil production process. Therefore, it is necessary to improve the above problems. Utility Model Content
