NOVELTY - The a vertical cutting knife (53) that is installed on the top side of a cutting board (5). Mounting plates (6) are fixedly installed on the top of a worktable (1) on both sides of the cutting board. The positions close to the top of the corresponding side of the two groups of mounting plates are fixed to the outer surface of the corresponding side of a top plate (7). An upper movable groove (71) is opened at the top of the top plate. The bottom end of the top plate is provided with a lower movable groove (72). The inner walls on both sides of the top plate are provided with sliding grooves (73). A fixing seat is fixedly installed on the top side of the top plate. A fixing bolt is movably screwed inside the fixing seat. Slide rails are fixedly installed on the top of the top plate on the two sides of the upper movable groove. Sliders are connected to the outer surfaces of the two sets of slide rails. Directional wheels are movably arranged inside the two sets of sliding grooves. USE - Cutting device for graphene film. ADVANTAGE - The vertical cutting knife and the transverse cutting knife are set to realize the longitudinal and transverse cutting of the graphene film so as to improve the practicability of the device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the cutting device for graphene film.
