Abstract
The utility model discloses an eccentric spiral stirring forced feeding device for high polymer materials. A material conveying shaft and a material stirring shaft of the eccentric spiral stirring forced feeding device are two fixed rotor shafts with spin axes parallel and mesh with each other in different directions. A central line of a spiral groove of the material output shaft and a central line of a spiral blade of the material stirring shaft have the same eccentricity with the respective spin axes. Two rotors mesh and rotate in different directions. The blade of the material stirring shaft is circumferentially provided with notches. Materials fed from a hopper are forcedly a conveyed in a feed barrel by different-direction meshing rotating of the material conveying shaft with the eccentric spiral groove and the material stirring shaft with the eccentric spiral blade. When feed is larger than plasticizing quantity of an extrusion system, materials return backwards through the notches among the spiral blades under the action of front pressure of the feeding device, and material conveying of the feeding system is cooperative with plasticizing transporting of the extrusion system.

The purpose of this utility model is achieved through the following technical solutions:
The eccentric spiral agitating type forced feed of a kind of macromolecular material device: comprise mass transport axle, material shaft and barrel; Mass transport axle and material shaft are arranged in the barrel, and the rotation of the rotation of mass transport axle and material shaft is fixed and be parallel to each other, the incorgruous engagement rotation of diaxon; All there are identical offset in the center line of mass transport axial screw groove and the center line of the propeller blade of material shaft with rotation separately, and two axle horizontal eccentric directions are identical; The blade of material shaft is arranged in the shape of a spiral, and along circumferentially there being equally distributed breach.Preferably described breach is 4.
The material that the utility model is added by hopper barrel by with eccentric spiral fluted mass transport axle with the incorgruous engagement rotation of the material shaft of eccentric propeller blade forced conveyance; When feeding capacity during greater than the plastics capacity of extrusion system, material is under the effect of drawing-in device forefront pressure, and by being arranged on the breach feed back backward between propeller blade, the mass transport ability that realizes feed system is worked in coordination with certainly with the plasticizing transport capability of extrusion system.
The utlity model has following advantage with respect to prior art: in the gap of convey materials, introduce the stretching field of force, improved the immixture of material in course of conveying; Adopt the blade on the material shaft that the material in the mass transport axle helicla flute is scraped, embrace roller and skid to prevent material, improved the ability of forced conveyance; The breach that exists between blade, plasticizing transport capability collaborative certainly of having realized the mass transport ability of feed system and extrusion system.

The specific embodiment
Below in conjunction with drawings and embodiments the utility model is further detailed, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As Figure 1-3, the eccentric spiral agitating type forced feed of a kind of macromolecular material device mainly comprises mass transport axle 10, material shaft 4 and barrel 6; Mass transport axle 10 and material shaft 4 are arranged in the barrel 6, and the rotation 8 of mass transport axle 10 is fixing and parallel to each other with the rotation of material shaft 49, the incorgruous engagement rotation of diaxon; All there is identical offset in the center line 2 of the spiral fluted center line 11 of mass transport axle 10 and the propeller blade 3 of material shaft 4 with rotation separately, and two axle horizontal eccentric directions are identical; The blade 3 of material shaft 4 is arranged in the shape of a spiral, and along circumferentially there being equally distributed 4 breach 5; Blade 3 can prevent that material from skidding at 10 armfuls of rollers of conveying axis on the material shaft 4, and the plasticizing transport capability of material forced conveyance ability and extrusion system is realized from collaborative.
The eccentric spiral agitating type forced feed of a kind of macromolecular material method: the material that is added by hopper 1 is by with eccentric spiral fluted mass transport axle 10 and material shaft 4 incorgruous engagements rotation forced conveyance with eccentric propeller blade 3, when feeding capacity during greater than the plastics capacity of extrusion system, material is under the effect of drawing-in device forefront pressure, breach 5 by 3 of propeller blades is feed back backward, and the mass transport ability that realizes feed system is worked in coordination with certainly with the plasticizing transport capability of extrusion system.
Embodiment 1
With reference to figure 1, Fig. 2 and Fig. 3, the extruder that has the eccentric spiral agitating type forced feed of macromolecular material device mainly is made up of the eccentric spiral agitating type forced feed of macromolecular material device unit II, plasticizing forming unit I and hopper 1, wherein, the eccentric spiral agitating type forced feed of macromolecular material device unit II mainly comprises mass transport axle 10, material shaft 4 and barrel 6; Plasticizing forming unit I mainly is made up of screw rod 7, barrel 6 and external molding port mould.Plasticizing forming unit I and forced feed unit II tandem compound are installed, and just plasticizing forming unit I is arranged on the rear end of the eccentric spiral agitating type forced feed of macromolecular material device unit II; But the mass transport axle 10 of the screw rod 7 of spiro rod plasticizing unit I and forced feed unit II can also one processing of coaxial fixedly assembling; Material shaft 4 and the 10 incorgruous engagements of mass transport axle, the rotation 8 of mass transport axle 10 is parallel and fixing with the rotation of material shaft 49, all there is identical offset in the center line 2 of the spiral fluted center line 11 of mass transport axle 10 and the propeller blade 3 of material shaft 4 with rotation 8,9 separately respectively, and two axle horizontal eccentric directions are identical.
Material is included into barrel and is fed forward after hopper 1 adds under the stirring of thrust, barrel 6 inner surface frictional force and the propeller blade 3 of mass transport axle 10 spiral shell ribs.In course of conveying, propeller blade 3 constantly scrapes the material in mass transport axle 10 helicla flutes, avoids material to embrace roller and skids, and realizes forced conveyance, and material is carried out premix; When the feeding capacity of the eccentric spiral agitating type forced feed of macromolecular material device II during greater than the plastics capacity of extrusion system, material is under the effect of drawing-in device front end elevated pressures, breach 5 that can be by 3 of propeller blades is feed back backward, and the mass transport ability that realizes feed system is worked in coordination with certainly with the plasticizing transport capability of extrusion system.Material is transported to continuously and stably among the spiro rod plasticizing unit I through forced feed device unit II and plastifies, homogenizing, extrudes, cools off through being connected a mouth mould on the spiro rod plasticizing unit I barrel 6 again, finalizing the design obtains goods.
