The extruder comprises an extrusion mold (1), a machine barrel (2), a tapered screw (3), a heating cooler (4), a vacuum aspirating chamber (5), an exhaust device (6), a feeding system (7), a distribution gear box (8), a deceleration transmission box (9), a drive motor (10), a coupling (11) and a pedestal (12). Due to the three characteristics of thorough exhaust, full mixing and generation of high pressure, the extruder can meet the basic requirement for wood-plastic composite material extrusion, thus improving the quality of wood-plastic composite material or product and achieving easier control of the processing process.
Description
Technical field
The utility model relates to a kind of extrusion equipment of producing wood plastic composite, particularly a kind ofly can expect that the end article one-step method produces the novel wood-plastic composite extruder of wood plastic composite from former.
Background technology
Wood plastic composite is the new generation of green environment-friendly materials that are surging forward in the world in recent years, it mainly makes raw material is natural fiber (wood chip, sawdust, stalk, rice chaff etc.), plastics (PE, PP, PVC, ABS, PET, waste plastics, regenerated plastics etc.), and additive and processing aid such as modifier, compatilizer, lubricant.The cost of wood plastic composite is lower, and alternative timber, plastic products are widely used in the world, has also obtained common concern at home, and application constantly enlarges.
The manufacturing process of existing Wood Plastics Composite Product generally has two kinds:
The one, use earlier the parallel double-screw extruder granulation, then with single screw extrusion machine plasticizing, pressurization, by formed in mould two-step method making fabrication technique, the shortcoming that this manufacturing process exists is to need to use two complete equipments, big, required manpower and the energy cost in the production space that takies is higher, raw material causes the decomposition variable color easily through twice plasticizing in addition, the difficult control of processing parameter, manufactured goods sometimes aberration big, have pore and a defective such as loose.
Another kind is to use that conical double screw extruder is mixing, dispersion, plasticizing, pressurization, formed in mould one-step method manufacturing process, the shortcoming that this manufacturing process exists is that dispersion, the plasticizing effect of raw material in process is poor, the goods inner materials is inhomogeneous, has only an exhaust outlet simultaneously, do not reach desirable exhaust effect, there is pore and loose goods inside, and screw rod and machine barrel quick abrasion, service life is short.
Summary of the invention
The utility model has solved above-mentioned the deficiencies in the prior art and problem, provide a kind of extrude stable, thorough exhaust, fully mixing, produce high multiplication of voltage and the high novel wood-plastic composite extruder of product density.
A kind of novel wood-plastic composite extruder of the present utility model comprises: extrusion die, machine barrel, conical screw, heating cooler, vacuum suction chamber, exhaust apparatus, feed system, distribution gear case, speed reducing transmission case, drive motors, shaft coupling, support, described two conical screws are incorgruous rotation or rotation in the same way in machine barrel, and the effective L D ratio of every conical screw is 25～60: 1; The exhaust apparatus number that is connected with machine barrel is 1～3.
During the utility model work, material stirs through feeder, again through the preheating of feeding machine barrel, be transported in the machine barrel then, under the effect of conical double-screw, flow material process preheating in flow process, fusion, mixing, natural exhaust, dispersion, kneading, plasticizing, vacuum exhaust, last extrusion molding to the port of export.Can on machine barrel, set up exhaust apparatus, can make that the moisture in the material is fully discharged, the inner pore-free of goods, thereby make the density of material of manufactured goods big, intensity is high, the longer service life of screw rod and machine barrel.
Specialty, a perfect wood plastic composite extrusion equipment must possess thorough exhaust, fully mixing, three necessary conditions of the high multiplication of voltage of generation, otherwise the quality of manufactured goods will be deposited just very big problem and defective.Carrying out thorough exhaust just needs to increase the quantity of exhaust outlet, so common conical double screw extruder just can not meet the demands (less because of its draw ratio, that an exhaust outlet can only be set); And carry out the fully mixing screw-rod structure that just needs big L/D ratio, so common conical double screw extruder can not meet the demands; (head pressure requirement 25～40Mpa) just needs the screw-rod structure of taper, so parallel double-screw extruder does not reach this requirement (head pressure is only about 18Mpa) at all to produce high multiplication of voltage.
The beneficial effects of the utility model have possessed above thoroughly exhaust, fully mixing, three necessary conditions of the high multiplication of voltage of generation exactly.Because the effective L D ratio of every conical screw is increased to 25～60: after 1, stable extrude and fully mixing that has guaranteed material improved Products Quality and density greatly; Because the increase of draw ratio can be set up more exhaust apparatus on machine barrel, make in the production process of wood plastic composite and fully finish exhaust; Because the increase of draw ratio has guaranteed that also conical screw can not twisted off after improving rotating speed, therefore machine production is improved greatly simultaneously, the energy consumption of specific yield also reduces greatly; Because screw-rod structure of the present utility model is taper, so also possessed the architectural feature that produces high multiplication of voltage.The utility model can satisfy the wood plastic composite machine-shaping of 50～90% string content; Can in mixing process, thoroughly slough in the wood-fibred 30% with interior moisture content and low-volatile; Can long-term safety production under 30～40Mpa screw back pressure situation; Can stably finish wood moulds the high density accumulation and smoothly extrudes ground head pressure requirement.
Therefore the utility model has possessed thorough exhaust, has extruded numerous advantages such as stable, that plasticizing capacity good, output is high, energy consumption is low, is a kind of novel extrusion equipment of producing wood plastic composite that is applicable to.
