▎ 摘　　要

NOVELTY - Winding type device comprises a chamber, an evaporation module, a coating module, a shaping module and a winding system, the winding system comprises an unreeling roller, a rolling roller, an evaporation main roller and a pattern generating roller, the chamber is divided into an evaporation working area and a non-evaporation working area by a clapboard, the evaporation module is set in the evaporation working area, the pattern generating roller is arranged between the coating module and the shaping module, the pattern generating roller through vacuum absorbing the wet film layer is not formed on the flexible base film of the pattern generating roller is partially removed to form a specific pattern on the flexible base film of the graphene composite film. USE - The winding type device is useful for preparation of graphene composite film (claimed). ADVANTAGE - The winding device: provides a cleaning environment for the preparation of graphene composite film by vacuumizing the sealed chamber and then filling the working gas, provides film thickness monitoring device to monitor the film thickness of the wet film layer in the width direction of the flexible base film in multi points, provides coating unit to perform dynamic feedback control according to the film-thickness monitoring signal on the area corresponding to the coating unit.
