Vertical powder filling mechanism, preparation method thereof and powder bowl filling device

The invention discloses a vertical powder filling mechanism, a preparation method thereof and a powder bowl filling device, and belongs to the technical field of powder filling. The powder sagger filling device comprises a vertical powder filling mechanism and a sagger used for receiving powder flowing out of the vertical powder filling mechanism. The vertical powder filling structure comprises a material bin assembly with a material barrel, a power assembly and a discharging spiral assembly with a transmission shaft, an auger and a material guide pipe. The charging barrel is provided with two coaxial connecting parts which are respectively used for connecting the transmission shaft and the material guide pipe; the auger is in transmission connection with the transmission shaft, and is provided with a limiting part for limiting the auger and the transmission shaft to deviate in the radial direction, so that the high coaxiality is achieved between the auger and the material guide pipe. And moreover, the other
