CN2650971Y discloses a kind of wooden extruder of moulding, adopted horizontal vertical two screw rods, horizontal screw rod plays plastication, and has added a mixing tube on vertical screw rod, loaded rolling bearing therebetween again, increased the melting effect of Wood plastic composite, but fundamentally do not solved the wood-fibred feeding and mould the problem that wooden compound system is stablized blending ratio, fiber feed difficulty, fiber is overstand in equipment, charing easily, fiber dispersion weak effect, equipment do not have the foaming unit.
CN1064059C discloses a kind of structure of fiber reinforced thermoplastics, method for making and production equipment thereof, fiber mainly adopts glass fibre, carbon fiber and composition thereof, the combing effect of described equipment utilization machine barrel or screw rod irregular surface and place one or more between extruder screw front end and the die head to install with latticed form at least and part is the combing degree that the pressing plate of wedge-shaped cross-section is controlled thermoplastic resin masterbatch fortifying fibre, the helical of fibre length and blend melt flows, it is too high to specification requirement that this control fiber size and fiber and thermoplastic resin mix degree methods, the particularly processing of machine barrel and screw surface structure, the equipment processing cost is too high, the problem of fiber feed difficulty does not solve simultaneously, and equipment does not have the foaming unit.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of good mixing effect, and volume is little, and easy to operate wood plastic composite is strengthened the blend plasticizing apparatus.
The technical solution of the utility model is: it comprises the identical blend plasticized screw I of a pair of structure, blend plasticized screw II, blend plasticized screw I and blend plasticized screw II all are divided into the plastic grain section of transporting, plastics fusion plastification section, fiber/plastic blend section successively, strengthen blend fluxing zone, homogenizing zone, metering section, strengthen the blend fluxing zone and are made up of 1～6 (preferred 2) mixing rotor of single-screw.
The mixing rotor of described single-screw is oval rotor, and shape of cross section is a tumbler shape; The mixing rotor of single-screw that is positioned at blend plasticized screw I is when blend plasticized screw I axis rotates, constitute the camming movement state, the mixing rotor of single-screw that is positioned at blend plasticized screw II also constitutes the camming movement state when blend plasticized screw II axis rotates.
The mixing rotor of single-screw in blend plasticized screw I from the summit to blend plasticized screw I axle core line and the angle the line of the mixing rotor of single-screw in blend plasticized screw II from the summit to blend plasticized screw II axle core be 0～180 °.
Blend plasticized screw I, when blend plasticized screw II is rotated simultaneously, the mixing rotor of single-screw that is positioned at blend plasticized screw I and the mixing rotor of single-screw that is positioned at blend plasticized screw II can form tangent cooperate or front and back interlace and mesh.
The assembly relation that the wood plastic composite of the utility model is strengthened between blend plasticizing apparatus and the extruder miscellaneous part is: described blend plasticized screw I, blend plasticized screw II is loaded in the barrel, constitute double-screw structure, described fiber/plastic blend section front end is installed fiber positive feed device, fiber positive feed device is fixed in outside the barrel, fiber positive feed device communicates through barrel fiber/plastic blend section, blend plasticized screw I, blend plasticized screw II end links to each other with main drive motor by gearbox, gearbox and main drive motor are installed on the extruder base, blend plasticized screw I, blend plasticized screw II end also is equipped with the plastics feeding device, and the plastics feeding device is driven by coupled feeding drive motors.
During work, plastic grain at first enters the plastic grain section of transporting, under the driving of corresponding blend plasticized screw, travel forward and enter plastics fusion plastification section, plastic grain is sent into plastics fusion plastification section end after being melted plasticizing, at this moment, the fiber positive feed device that is positioned at fiber/plastic blend section front end is pressed into fiber, polymer melt is under blend plasticized screw shearing force of answering and axial compressive force effect, entering fiber/plastic blend section tentatively mixes, then, enter again and strengthen the blend fluxing zone, at this moment, fiber evenly mixes under the reinforcement shear action of the mixing rotor of single-screw with plastics, and last, mixture is by the homogenizing zone and the metering section extrusion molding of corresponding blend plasticized screw.
