Carbon dioxide phase change expansion excitation tube charging machine

The utility model provides a charging machine for a carbon dioxide phase change expansion excitation tube. The charging machine comprises a rack, a vibration component and a charging component, the vibration part and the charging part are both connected with the rack, the charging part is used for filling raw materials into the excitation tube shell, and a discharging port of the charging part is used for being communicated with an opening of the excitation tube shell; the vibration part is used for being detachably connected with the excitation tube shell so as to drive the excitation tube shell to vibrate. When the carbon dioxide phase change expansion excitation tube charging machine is used, the excitation tube shell is detachably connected with the vibration component, the excitation tube shell is kept to be vertically arranged, the open end of the excitation tube shell is made to deviate from the ground, then the charging component is used for assisting manual charging, and in the charging process, the
