Electromagnetic induction heating nozzle device of metal fuse deposition printer

The invention discloses an electromagnetic induction heating nozzle device of a metal fuse deposition printer. The electromagnetic induction heating nozzle device comprises a wire feeding device, a heating device and a nozzle, wherein the wire feeding device is a self-adaptive wire feeding device, a heating mode of the heating device is electromagnetic induction heating, the nozzle is a high-temperature ceramic crucible nozzle, metal materials enter the area of an electromagnetic induction heating device under the action of the self-adaptive wire feeding device and are converted into a moltenstate at high temperature, then molten metal is reserved through fine holes of the high-temperature ceramic crucible nozzle, and layer-by-layer printing is achieved. According to the electromagnetic induction heating nozzle device, the problems that the metal fuse deposition printer is difficult to feed and withdraw, low in resistance heat heating efficiency, low in heating speed, uneven in heating, prone to blockage of t
