▎ 摘　　要

NOVELTY - The device has a box housing (2) whose bottom end is fixed with two first support column (5). One ends of the two second support columns (12) are respectively fixedly connected to a top end and a bottom end of an inside of the box housing. The positions of the two second support columns are aligned. Other end of the two second support columns is equipped with a roller compactor (16). Two heating plates (17) are mounted on one side of the roller compactor. A third support column (15) is arranged on one side of the two second support columns. One ends of the two third support columns are respectively fixedly connected to a top end and a bottom end of an inside of the box housing. Other ends of the two third support columns are respectively fitted with a bonding block (18), and the positions of the two bonding blocks are opposite. USE - Device for preparing graphene prepreg. ADVANTAGE - The release paper strip is rotated between the driving wheel and the driven wheel to increase the reuse of the release paper strip. The manufacturing cost is reduced, and the upper rolling plate is driven and raised by the electric telescopic rod to effectively ensure the uniform rolling of the graphene powder. A nozzle is attached to the inside of the bonding block to be connected to an external refrigerator, and the semi-cured epoxy film after heating is effectively cooled. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene prepreg.
