NOVELTY - The utility model relates to the technical field of graphene, especially relates to a coating device of graphene self-heating film. The coating device of graphene self-heating film comprises an upper coating mechanism and a lower coating mechanism, the upper coating mechanism comprises a storage groove, the lower end of the storage groove is connected with the sponge through the clapboard, the storage groove is connected to the lower coating mechanism through the pump pipe, the lower coating mechanism comprises a nozzle which is provided with upper end, the lower end of the nozzle is connected with the box body of the lower coating mechanism through a hose. The structure of the coating device of graphene self-heating film is simple, the upper coating mechanism is provided with a stirring device, the graphene in the storage groove is hardened, at the same time, it is conveyed to the lower coating mechanism through the connecting pipe, the lower layer is sprayed, the falling material can continue to fall into the lower coating mechanism, it does not waste the effect .
