Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of oven, concretely to a novel oven of coating machine for carbon-coated aluminum foil. BACKGROUND

[0002] The carbon-coated aluminum foil is a kind of composite material coated with carbon layer on the surface of aluminum foil. It is mainly used in energy storage devices such as lithium batteries and supercapacitors as current collector. The introduction of carbon coating layer can improve the conductivity, corrosion resistance and adhesion of aluminum foil with active materials, thereby improving the performance and life of the battery. The carbon-coated aluminum foil has the advantages of light weight, high strength and good conductivity, and is widely used in the field of new energy. After the slurry is coated on the surface of the aluminum foil by the coating machine, the slurry is fixed and formed with the aluminum foil. Therefore, after coating, the aluminum foil needs to be transferred to the oven for drying treatment.

The drying device usually faces the front surface of the aluminum foil with a coating layer, so that the coating layer far from the aluminum foil is first heated and solidified. During the drying process, the coating layer is dried on one side, and the bonding between the coating layer and the surface of the aluminum foil is difficult to heat, resulting in uneven drying of the coating layer and affecting the product quality.
