NOVELTY - The utility model relates to the technical field of preparation technique of graphene, claims a sampler and graphene production device, the sampler comprises a main body sleeve pipe a sampling part, the sleeve pipe body is provided with a cylindrical sampling cavity and an opening at one end, the sampling part is at least partially located in the sampling cavity, the opening end of the main body sleeve pipe provided with a feeding port, the periphery of the feeding port is provided with a feeding port flange connected to the sampling port of the conveying pipe, the pipe sleeve pipe of the main body close to one end of the feeding port is provided with a discharging port connected with the sampling cavity, the sampling part is set to be capable of extracting the material conveyed by the conveying pipeline to the sampling cavity through the feeding port, and discharging from the discharging port. Through said technical solution, it can ensure the system without stopping in the production process can be sampled at any time, ensures the fluency of the sampling port, the sampler can repeatedly use sampling for many times, reduces the loss of the device pipe. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production device for graphene.
