The utility model relates to a viscose metal fiber preparation device. The viscose metal fiber preparation device comprises a viscose stock solution pipeline (1), a filter (2) and a spinning pressure feed barrel (3); the viscose metal fiber preparation device is characterized by further comprising a metal raw stock barrel (4) on which a stirrer (4.1) is arranged; an ultrasonic vibrating rod (4.2) is arranged in the metal raw stock barrel (4) next to an outlet; the outlet of the metal raw stock barrel (4) is orderly connected to a first heat exchanger (7) and an annular porous nozzle (6); a static mixer (5) is arranged in the viscose stock solution pipeline (1) ahead of the spinning pressure feed barrel (3); the annular porous nozzle (6) is arranged in the viscose stock solution pipeline (1) ahead of the static mixer (5); a second heat exchanger (8) is further arranged on the viscose stock solution pipeline (1) between the annular porous nozzle (6) and the filter (2). The viscose metal fiber preparation device has the advantages of low metal raw stock loss, good dispersibility, even mixing, and avoidance of pipeline blockage during mixing.
