▎ 摘　　要

NOVELTY - The device has a second feeding motor (5) whose output end drives a second conveying auger inserted into a second conveying pipe (4). A discharge nozzle (2) is connected to an end of the second conveying pipe. Solenoid valves are installed on a discharge branch pipe and a distributing pipe. A controller (6) is connected to the second feeding motor, a first stirring motor, a second air pressure detection sensor (8), a second vacuum pump (9) and a third vacuum pump (10). A first heating device (11), a first vacuum pump (14), a first feeding motor (16), an auxiliary motor (20), a first air pressure detection sensor, a first temperature detection sensor, a second stirring motor, a third air pressure detection sensor, a second heating device, a solenoid valve and a second temperature detection sensor are electrically connected. USE - Melting and mixing device for processing graphene modified plastics. ADVANTAGE - The device can effectively pre-mix and raise the temperature of the raw material through the premixing tank and avoids the problem that the traditional mixing device needs to wait for material heating to finish the low working efficiency when using. The device can effectively provide continuous output material to the outside through the set of mixing tank, so as to be more suitable for the production process of continuous production. The device includes the good heat preservation and heat insulation capability, which can effectively avoid the loss of heat, so as to effectively save the energy.
