Description
Technical field
The utility model relates to a kind of high-efficiency multi-screw extruder, belongs to field of plastic machinery.
Background technology
For adapting to the process requirements of more high filler loading capacity, domestic and international supplier develops the multi-screw extruder of various abrasive disk type extruder, reciprocating screw type extruder and various combination successively; In recent years, adapt to the direct process requirements of sensitive material, multi-screw extruder becomes the strength that compounding market develops rapidly gradually; Traditional multi-screw extruder compares and common are Planetary Screw Extruder, ring screw extruder etc., in recent years, different vendor and scientific research institutions have developed del successively and arrange the new architectures such as three-screw extruder, word order three-screw extruder, word order four screw extruder, MRS multi-screw extruder, and the direct system of processing that multi-screw extruder and singe screw or twin-screw combine, play special effect in different field; Traditional multi-screw extruder efficiency comparison is low, and therefore this is urgent problem.
Summary of the invention
The purpose of this utility model is to provide a kind of high-efficiency multi-screw extruder.
Problem to be solved in the utility model is the defect that existing multi-screw extruder efficiency comparison is low.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of high-efficiency multi-screw extruder of the utility model, comprise base, motor, gear-box, charging aperture, hopper, front barrel, driving screw, sub-screw, rear machine barrel, mold base and bracing frame, described motor is arranged on base afterbody, gear-box is fixedly mounted on base, and motor rotation axis is connected with gear-box; Front barrel passes through together with Flange joint with rear machine barrel, and rear machine barrel front portion is provided with bulge, and the other one end of front barrel is fixed on gear-box, and rear machine barrel is fixed on base by bracing frame; Have a charging aperture above front barrel, hopper is bolted on charging aperture; Driving screw is arranged in front barrel and rear machine barrel, and driving screw shank is connected with gear-box; Sub-screw has the six roots of sensation, and sub-screw is uniformly distributed and is arranged in rear machine barrel bulge, and every root sub-screw engages with driving screw, and driving screw rotates and sub-screw can be driven to rotate, and sub-screw and driving screw reversely rotate; Rear machine barrel afterbody is provided with mold base, can fixed mould by mold base.
The utility model has the advantages that: because rear machine barrel is provided with bulge, and in bulge, be provided with six barrel grooves, the sub-screw with extruder axis being parallel is respectively fitted with in these barrel grooves, every root sub-screw engages with driving screw, driving screw rotates and sub-screw can be driven to rotate, therefore other driving need not be set, there is the simple feature of mechanism; These little barrel grooves are opened in rear machine barrel bulge, have the place of 30% to be open, thus can optimize entering and easily what discharge of melt, therefore have higher extrusion efficiency.
