Description
Technical field
This utility model relates to extruder technology field, especially relates to a kind of extrusion for lazy flow plastic processing
Machine screw rod.
Background technology
Screw rod is one of kernel component of extruder equipment, due to screw rod high-speed rotary then produces shearing effect with barrel
Effect, plastic raw materials mixing and along screw channel carry, make solid plastics raw material by outside barrel electric heating piece heat with
Under the shear heat effect that screw rod produces, the internal intensification of barrel is made to be melt into melt state.The range of application of extruder and productivity ratio are all
Directly depend on the architectural characteristic of screw rod, such as screw combinations, each segment length ratio etc..
But, extruder in the market for lazy flow plastics when extruding pelletization, due to material transmission imitate
The poorest, that fracture often occurs problem.The most necessary existing extruder equipment is transformed, to be applicable to low stream
The production of dynamic property plastics, and the screw arbor assembly adjusting twin screw is most effective, most economical method.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of extruder spiral shell for lazy flow plastic processing
Bar, it is abundant that it is blended effective, material plasticizing, the excellent material performance after processing.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
A kind of extruder screw for lazy flow plastic processing, including feed zone, transportation section, compression melt zone and meter
Amount homogenizing zone, described screw rod comprises some FAMME screwing elements, subtracts diameter thread element and three kneading blocks；Described
On FAMME screwing element, screw channel is set；Described FAMME screwing element, subtract diameter thread element and three kneading blocks are arranged
In the transportation section of screw rod, compress melt zone and metering homogenizing zone；Axial overall length after described FAMME screwing element superposition accounts for spiral shell
To two/15th 1/10th of bar total length；Described subtract diameter thread element superposition after axial overall length to account for screw rod total
10th to ten/12nd 1/8th of length；Axial overall length after described three kneading block superpositions accounts for screw rod total length
1 to two/15th ten 1/5th.
Preferably, the degree of depth of described screw channel is 1-5mm.
Preferably, subtracting diameter thread element described in is that dextrorotation subtracts diameter thread element, left-handed subtracts in diameter thread element
At least one.
Preferably, described three kneading blocks are three kneading blocks of forward, reverse three kneading blocks, neutrality
At least one in three kneading blocks.
Preferably, subtract diameter thread element described in and be arranged at feed zone.
Preferably, described FAMME screwing element is arranged at transportation section.
Preferably, described three kneading blocks are arranged at compression melt zone and metering homogenizing zone.
The beneficial effects of the utility model:
Compared with prior art, this utility model FAMME screwing element, subtract diameter thread element and three kneading block units
Part combines accordingly as the spiral shell block element of extruder.The mixed of three kneading blocks is strong, can improve screw rod
Blended effect to material, it is possible to make the abundant fusion plastification of material.When FAMME screwing element rotates, material can be caused at circumference
The flowing that direction is bigger, when making material flow through spiral shell rib top, by controlled shearing.Subtract diameter thread element, beneficially material to exist
Extruder barrel transmits, it is adaptable to the production field of lazy flow plastics.
