▎ 摘　　要

NOVELTY - A rolling device comprises base (1) fixedly installed with rolling mechanism main body (2) at upper surface. The rolling mechanism main body is fixedly installed with feeding groove (4) at upper end, and provided with access door at one side, discharging port at other side and first forward roller (27) at inner portion. The first forward roller is provided with first reverse roller (29) and second forward roller. The lower end of second forward roller is provided with second reverse roller provided with supporting roller. The discharging port is fixedly installed with roller conveyor installed with supporting frame, and provided with third motor. The supporting frame is provided a detecting light curtain mechanism. The third motor is provided with transition table provided with transition roller and winder. USE - The device is used for graphene film. ADVANTAGE - The device solves the problems about not able to detect production quality in real time and production of thin and non-uniform graphene film if pressing roller is loosened or feeding port deviates. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of internal structure of rolling device.
