NOVELTY - The utility model claims a coating processing and coating device for graphene biological material, comprising a base, a nozzle assembly, a pressure spring, a second clamping plate; a traction wire and a collecting cylinder; the upper surface of the base is fixedly mounted with a supporting column; and the top of the supporting column fixedly connected with with a fixing plate; and the top side of the fixing plate is movably mounted with a nozzle assembly; one end of the pressure spring is fixedly connected with the first clamping plate; and the other end of the pressure spring is fixedly connected on the fixing block; and the fixing block is fixedly installed on the side of the fixing plate. The coating processing and coating device for graphene biological material, only needs to push the device to start coating, compared with the handheld device is more labour-saving, and the single coating area is larger, so as to improve the working efficiency, and the clamping step of the work piece is more convenient, and can recycle the graphene biological material scattered in the coating process; It saves raw material.
