NOVELTY - The method involves injecting waste plastic, polyethylene and auxiliary agent into a high-speed mixer. The waste plastic, the polyethylene and the auxiliary agent are heated for 30-45 minutes under assistance of microwave radiation. A product is input into a single-screw extruder for mixing and melting. Graphene powder is pre-processed. The graphene powder and nanometer aluminum oxide are input into a high-speed shearing machine. Water and thermoplastic starch are added to the graphene powder and the nanometer aluminum oxide. Molten material and the pre-processed graphene powder are transmitted into a double-screw extruder. A waste plastic hot air melting regeneration particle processing device is used to perform hot air melting on an object. A continuous grain cutting device is used to granulate the object. USE - Method for producing composite regenerative plastic with high toughness. ADVANTAGE - The method enables realizing fast mounting and dismounting of a cutting assembly by a quick-release assembly and locking and limiting the quick-release assembly by a locking piece without performing complicated screw fixing operation. The method allows a fixing seat to drive a movable connecting seat to rotate along the cutting assembly so as to drive a pressing roller to be pressed on a driving roller, thus ensuring material stable input when feeding. The method enables realizing quick change of a single convex plate without completely replacing convex plate bodies in a simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high-toughness composite regenerative plastic continuous granulating device. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a high-toughness composite regenerative plastic continuous granulating device. 2Controller 3Guide wire component 4Movable pressing component 5Driving component 6Movable protective assembly 7Discharge pipe
