The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and plastifies evenly and the higher planetary extruder of operating efficiency.
The technical solution of the utility model is achieved in that a kind of planetary extruder, comprise barrel and be positioned at the feeding device that barrel top arranges, be provided with driving screw in this barrel, this barrel comprises discharging opening, the end of described barrel discharging opening also is connected with secondary barrel, is provided with sub-screw in this pair barrel, and an end of this sub-screw is connected with driving screw, the outer wall of this sub-screw some small screws that have been connected with a joggle, and the inwall of sub-screw is provided with the internal screw thread that is meshed with small screw.
By adopting technique scheme, because sub-screw and each small screw constantly rotate, make material in the thread gap of rotating that is meshing with each other, be subjected to strong extruding, roll over and stretch and multiple power effect such as shearing, make raw material constantly be stirred, mix in this section, become molten condition at last, evenly plastified, be pushed to the sub-screw leading portion gradually, extruded from the outlet of secondary barrel.
The utility model further is set to: the end of described sub-screw and driving screw is provided with connection bump, driving screw be provided with connection bump suitable be connected groove.
By adopting technique scheme, connection bump with is connected groove and can constitutes connecting portion, connect simply, reliably, and be convenient to realization.
The utility model also further is set to: described feeding device comprises the accumulator that is back taper and is positioned at the feed appliance of accumulator bottom, this feed appliance is the hollow setting, this hollow space constitutes the runner of feed liquid, be provided with mixing component in the described accumulator, this mixing component comprises drive rod and motor, the outer wall of hypomere is provided with external screw thread in the described drive rod, and this externally threaded being oriented down arranges, and the upper end of drive rod passes the accumulator setting, and the upper end of this drive rod is connected with motor.
By adopting technique scheme, the mixing component of setting can effectively stir material, be difficult for solidifying, and the external screw thread that arranges on the drive rod, and external screw thread arranges down, helps feed liquid to move down, has improved the flowability of material.
The utility model also further is set to: the middle hypomere of described drive rod is positioned at feed appliance setting, and external screw thread is positioned at feed appliance.
By adopting technique scheme, effectively raise the flowing velocity of the feed liquid in the feed appliance, and simple in structure, be easy to realize.
