▎ 摘　　要

NOVELTY - The method involves recycling and concentrating production raw materials, crushing the production raw materials after recycling the production raw materials, and then cleaning crushed plastics to remove dust and impurities in the plastics. The material proportions required by preparing graphene quantum dot cloud velvet is blended, raw materials after proportioning are mixed, and the raw materials are sucked into a storage bin at the highest layer through negative pressure. The raw materials are stirred and mixed in a stirring bin. The raw materials after stirring are dried, and the raw materials are extruded and melted through a screw rod after stirring. The raw materials are changed into slurry. One end of a shunt pipe (59) is fixedly connected on an upper surface of the exhaust pipe, and the other end of the shunt pipe is fixedly connected on a right side of a locating box (41) and is connected with an air inlet cavity (44). USE - Preparation method of quantum dot graphene used for attracting chemical, physical, material and biological fields of interest of scientists. Can also be used in photoelectric detection material and preparation technology, trend and national important requirement. ADVANTAGE - The cloud silk is shaped at the same time to avoid the problem that the cold air blown out by the cloud wool yarn in a single direction causes the deformation of the cloud silk. The cloud wool wire is more stable in the shaping pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a preparation method of quantum dot graphene. 1Shaping box 2Fixing plate 3Supporting leg 4Shaping mechanism 41Locating box 42Mounting groove 43Shaping pipe 44Air inlet cavity 45Driving cavity 46Blade plate 52Air outlet pipe 53Shunt box 54Exhaust pipe 55Connecting pipe 56Fan 57Circulating pipe 58Spiral baffle 59Shunt pipe
