The utility model relates to the technical field of sampling equipment, in particular to a coating surface density sampler which comprises a workbench, a flattening mechanism and a sampling cutter, the flattening mechanism comprises a bearing base and a pressing plate, the pressing plate is provided with a sampling opening, and the sampling opening is located above the bearing base and corresponds to the bearing base; materials are placed on the bearing base, the material pressing plate presses downwards to enable the materials to be flat, the flattened materials are exposed out of the sampling opening, and the sampling cutter is installed on the workbench in a sliding mode and corresponds to the sampling opening. Under the action of pressure, materials are flattened, wrinkles are smoothed, samples are punched out from a sampling opening during sampling, the punched samples are high in size precision, small in burr, little in powder falling, good in quality and high in follow-up detection precision, the devic
