Description

technical field [0001] The invention relates to a graphene processing equipment, in particular to an automatic material spraying calendering equipment and a material spraying calendering process for a graphene heat conduction film. Background technique [0002] With the world's energy shortage and environmental deterioration, renewable energy and clean energy are becoming more and more popular, which has also led to the rapid development of new energy and energy storage methods such as nickel metal hydride, lithium ion, and solar cells. [0003] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is a planar film composed of carbon atoms with sp2 hybrid orbitals forming a hexagonal honeycomb lattice, a two-dimensional material with a thickness of only one carbon atom. [0004] Due to the special structure of graphene, researchers have been paying attention to the development of graphene-related products, and the multiple uses of graph...

Problems solved by technology

[0007] However, the main disadvantage of the above two production methods is that the graphene ink or graphene slurry contains solvents and other materials, which leads to the disadvantages of large power consumption, high operating costs, and failure to meet thermal conductivity parameters and indicators in the entire spraying equipment.

[0008] In addition, after the graphene heat-conducting film is processed, it generally needs to be rolled. The existing rolling processing device generally includes two upper and lower rollers, and two or four synchronous motors input pure torque transmission to the upper and lower rollers respectively. Power, however, the electrodes used are all servo motors, the control accuracy is low, and there are roll coaxiality errors and bearing manufacturing errors that affect the uniformity of the thickness of the rolled object
