▎ 摘　　要

NOVELTY - The device has a submerged cleaning tank (102) whose bottom end is installed with flow-adjustable drain pipes. An outer edge surface of a lamination roller (4) is provided with two water absorption grooves (401) facing an upper portion of a graphene film main body (2). An edge-chamfered boss (103) is provided with a water absorption groove (10301). A side surface of a cleaning and drying box (1) is provided with a negative pressure device. A middle portion of a processing channel of the cleaning and drying box is provided with two groups of wiping flannels tensioned by tensioning rollers. A surface of the wiping flannel is in contact with a surface of the graphene film body. An adjustable drying equipment is installed on a side surface of the processing channel of the cleaning and drying box away from an edge chamfered boss. USE - Graphene film preparation device. ADVANTAGE - The device is simple in structure and easy to realize convenient and reliable cleaning and drying of the graphene film. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged view of a graphene film preparation device.
