Description
Technical field
The utility model relates to the production equipment technical field for chemical industry thermoplastic aspect.
Background technology
Chinese invention patent number is: 201010261504.0 disclose the kind double screw extruder, comprise feeding device, driving mechanism, barrel and vacuum extractor, described feeding device comprises hopper body and the intrinsic spiral agitator of hopper of barrel one end, the top of hopper body has top cover, has feeding hopper on the top cover of hopper body, motor and decelerator, described vacuum extractor comprises the exhaust outlet on the barrel, Pressure gauge, barometric damper and vavuum pump, the middle part of described barrel is provided with auxiliary rabbling mechanism, described auxiliary rabbling mechanism comprises that axis is the helical stir axle of vertical state and drives the stand-by motor that the helical stir axle rotates, described barrel and hopper body) between be provided with side feeding portion, described side feeding portion comprises the material feeding box that communicates with barrel, feed screw, drive feeding motor and the reduction box of feed screw, described feed screw is positioned at the below of hopper body, and the end of feed screw feeds material feeding box.
Single screw extrusion machine fricative heat of when work is bigger, and the suffered shearing of material is also inhomogeneous, and conveying capacity can be less, and extrusion capacity is lower, and speed of production is slow, and efficient is low; Material time of staying in barrel is short, mix inhomogeneous, the plastic pellet inferior quality of producing.
The utility model content
The utility model purpose aims to provide a kind of twin-screw combination with efficient plasticizing capacity, and these plastics with twin-screw combination of efficient plasticizing capacity plastify the production efficiency height of production equipment, the product quality height of producing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of twin-screw combination with efficient plasticizing capacity, comprise twin-screw main frame body, described twin-screw main frame body is provided with the feeding machine of screw metering, described twin-screw main frame body is equipped with the reduction box system, described reduction box system comprises gear reduction box and gear distribution box, described twin-screw main frame body is provided with extrusion system, described twin-screw main frame body is equipped with screw rod, and described screw rod becomes the meshing shape structure of two head threads.
Described a kind of twin-screw combination with efficient plasticizing capacity, the diameter of its screw rod is 65mm.
Described a kind of twin-screw combination with efficient plasticizing capacity, the threaded components of its extrusion system is the structure of building block system combination.
The beneficial effect of this utility model is, because this has the twin-screw combinations produce efficient height of efficient plasticizing capacity, the product quality height of producing.This twin-screw combination fricative heat of while with efficient plasticizing capacity is less, also conveying capacity comparatively even, twin-screw is bigger for the suffered shearing of material, more stable, the high efficiency of extrusion capacity, reduced the cost of enterprise, material time of staying in barrel is long in addition, mix, the plastic pellet quality of producing is higher.
