The charging device of the plasticizing charging
machine comprises a shell, a vibration main shaft and stirring blades, a circular-truncated-cone-shaped stirring cavity is formed in the shell, a cylindrical discharging opening is formed in the lower end of the stirring cavity, an upper cover is arranged at the upper end of the shell, and a vertically-through mounting hole is formed in the middle of the upper cover; a stirring blade transmission
assembly is arranged at the upper end of the mounting hole, the stirring blade is connected with the lower end of the stirring blade transmission
assembly, an upper closing plate is arranged at the position, located above the stirring blade transmission
assembly, of the upper end of the upper cover, and the middle of the upper closing plate is sleeved with a vibration assembly which vibrates up and down. The lower end of the vibration spindle penetrates through the stirring cavity and is located in the middle of the discharging port, the inlet, close to the discharging port, of the vibration spindle is sleeved with a second discharging blade, and the outlet, close to the discharging port, of the vibration spindle is sleeved with a first discharging blade. The stirring assembly, the vibration main shaft and the vibration assembly are combined, and efficient stirring and guiding of materials in the stirring cavity are achieved.
