Abstract
The utility model relates to the field of machinery, and particularly relates to a feeding device of a planetary extruder. The feeding device comprises a material storage device in the shape of an inverted cone and a material delivery device located on the lower portion of the material storage device. The material delivery device is hollow, and the hollow portion forms a runner of material liquid. A stirring assembly is arranged in the material storage device and comprises a driving rod and a motor. External threads are arranged on the outer wall on the middle lower section of the driving rod and are arranged downwards. The upper end of the driving rod penetrates out of the material storage device and is connected with the motor. The feeding device has the advantage that the arranged stirring assembly can effectively stir materials and enable the materials not to be solidified easily. The outer threads are arranged downwards on the driving rod, so that the material liquid can move downwards favorably, and material mobility is improved.

Technical field
The utility model relates to mechanical field, refers to a kind of feeding device of planetary extruder especially.
Background technology
The processing that planetary extruder extensively applies to feed backs such as PVC, PE is equipped with long barrel drive rod design, can allow plastic raw materials fully plastify in barrel.Existing planetary extruder comprises barrel and is positioned at the feeding device that barrel top arranges, this feeding device comprises accumulator and the feeder that is back taper, the bottom of this this accumulator of feeder bathroom, feeding device, feed liquid easily solidify with accumulator in, cause the mobile of feed liquid to have some setbacks, influence the efficient of materials device on the whole; And this feed liquid is just injected in the barrel without supercooling, because feed liquid self temperature is higher, owing to heat expansion, has damaged the outer wall of screw rod to a certain extent.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of feed liquid flow smooth and easy, loading efficiency is higher and have the feeding device of the planetary extruder of cooling-down effect.
The technical solution of the utility model is achieved in that a kind of feeding device of planetary extruder, comprise the accumulator that is back taper and be 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 further is set to: the outer wall of described feed appliance is provided with cooling device, and this cooling device comprises cooling tube, and outer wall and sealing that this cooling tube is sheathed on feed appliance arrange, and the outer wall of cooling tube is provided with water inlet and delivery port.
By adopting technique scheme, effectively feed liquid is cooled off, in the time of in feed liquid enters barrel, protected the outer wall of screw rod, improved service life.
The utility model also further is set to: the outer wall of described accumulator is provided with the clout outlet.
By adopting technique scheme, this clout outlet is effectively cleared up the clout in the accumulator, has improved serviceability greatly.
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.
