▎ 摘　　要

NOVELTY - The device has a feeding port (1), a melting bin (2), a cutting mold (3) and a cutting mechanism (4). The cutting mold is evenly provided with through openings (41), and the cutting mold is provided with a water ring channel and a water ring interface (43). The cutting mold and the melting bin are slidably connected by a connecting unit (5), and the cutting mold is communicated with the melting bin. The connecting unit is provided with a first annular block, a connecting block (52) and a telescopic spring. USE - Preparation device of graphene modified plastic used in petrochemical industry chain, plastic product of general plastic and engineering plastic, improving flame retardance, strength, impact resistance, toughness and other aspects of plastic product. ADVANTAGE - The device pulls the connecting block through the working staff so as to slide out from the through groove, and pulls the cutting mold matched with the work staff to reach the purpose of disassembling the cutting mould from the melting chamber, so that the cutting die falls on the ground from the hand working staff ensures the implementation effect of the device, thus reducing the time of dissembling the bolt and the nut of the worker, and hence improving the efficiency of worker maintaining and maintaining the device. The device prevents the material cutting mold from being working staff outwards, because the graphene modified plastic in the through hole is extruded by graphene modified plastics and melting chamber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene modified plastic. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the preparation device of graphene modified plastic. 1Feeding port 2Melting bin 3Cutting mold 4Cutting mechanism 5Connecting unit 41Through opening 43Water ring interface 52Connecting block
