▎ 摘　　要

NOVELTY - The device has an unwinder (1), a first conveyor (2), an auxiliary components (3), a spraying machine (4), a second conveyor (5), a carbonization furnace (6), a graphitization furnace (7), a third conveyor (8), a calender (9) and a winder (10) placed in sequence along a process direction. A dispersing component (11) is connected to the spraying machine through a conveying pipe for preparing graphene dispersion. A second dispersing portion is installed in the tank and located under the filter screen. A fixed shaft is installed on a fixed plate and arranged coaxially with the fixed plate. One end of first transmission shaft is installed obliquely on a first drive shaft and the other end is installed on the fixed shaft. Several dispersion balls are installed on the dispersion block and provided with a spherical structure. The dispersing blocks are in a circular array around the central axis of the second dispersing circle. USE - Device for producing graphene heat dissipation film. ADVANTAGE - The dispersion efficiency of device and the inability to fully disperse graphene through the dispersion component are improved. The multi-stage dispersion is realized through the first dispersing portion, the second dispersing portion and the filter screen so as to ensure the continuous dispersion of graphene. The dead angle of dispersion through the inclined main dispersion disc, auxiliary dispersion disc, and transition dispersion disc is reduced. The multiple primary dispersing blocks, auxiliary dispersing blocks, transitional dispersing blocks and graphene aggregate particles are utilized to collide and rub each other, so that the graphene is fully dispersed and disassembled in the solvent. The dispersing block and the dispersing ball continuously collide with the graphene, so that the dispersion is fully dispersed, the dispersion efficiency is ensured, and the dispersion time is reduced. The substrate is transported and preheated through auxiliary components so as to ensure that the solvent evaporates quickly when the dispersion liquid contacts the substrate to avoid graphene agglomeration, for obtaining a uniform film, which solves the problem of the formation of small droplets and agglomeration after the existing graphene dispersion liquid is sprayed on the substrate. The height of the first belt pulley is adjusted by rotating the adjusting shaft to realize the adjustment of the height of the transmission channel, so as to adapt to the transmission work of different substrates.
