Transformation device for solid powder sampling system

The utility model relates to a transformation device for a solid powder sampling system. The transformation device comprises a powder sampling tank and a sampling mechanism, the sampling mechanism comprises a sampling pipe, a material blocking assembly, a sampling bag, a first electric switch valve and at least one second electric switch valve, a sampling opening is formed in the bottom of the powder sampling tank, the sampling pipe is vertically arranged, the first end of the sampling pipe is connected with the sampling opening, and the second end of the sampling pipe is connected with the sampling bag. The plurality of second electric switch valves are arranged on the sampling pipe at intervals, and the first electric switch valve is arranged on the sampling pipe. The material blocking assembly is arranged on the sampling pipe and located between the first electric switch valve and the sampling bag. A process pipeline is vertically connected to an original sampling opening, so that the sampling opening of a
