Abstract
The utility model discloses an extruder screw rod for processing of high strength thermoplastic elastomer, including feed zone, transport section, compression melt zone and measurement homogenization section, the screw rod contains a plurality of profile of tooth hybrid element, three screw elements and three meshing components, profile of tooth hybrid element, three screw elements and three meshing components set up in transport section, compression melt zone and the measurement homogenization section of screw rod. The utility model discloses regard as profile of tooth hybrid element, three screw elements and three meshing components the spiral shell piece component of extruder to carry out corresponding combination, can improve the blend effect of screw rod to the material for the heat transfer performance of screw rod prolongs the dwell time of material in the barrel, is applicable to high strength thermoplastic elastomer's production field.
Description
Technical field
The utility model relates to extruder technology field, especially relates to a kind of extruder screw for the processing of high-strength thermoplastic elastomer.
Background technology
Screw rod is one of kernel component of extruder equipment, because screw rod high-speed rotary transfers to produce shearing effect effect with barrel, plastic raw materials is mixing and carry along screw channel, under making the solid plastics raw material electric heating piece be subject to outside barrel heat the shear heat effect produced with screw rod, barrel inside is made to heat up and be melt into melt state.The range of application of extruder and productivity ratio all directly depend on the architectural characteristic of screw rod, as screw combinations, each segment length ratio etc.
But, for high-strength thermoplastic elastomer when extruding pelletization, the problem of the serious and feeding difficulty of equipment attrition usually can be there is in parallel dual-screw extruding machine in the market.Owing to adding a large amount of reinforcing agents, very serious to the wearing and tearing of screw rod and barrel, cause frequent parking, cause the maintenance cost of equipment to rise.And due to the SEBS that processes raw material be fluffy dusty material, not easily blanking, often there will be the problem of fracture.Therefore necessaryly transform the existing equipment of hing surface in the same way, to be applicable to the elastomeric production of high-strength thermoplastic, and the screw arbor assembly adjusting twin-screw is effective, the most most economical method.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of extruder screw for the processing of high-strength thermoplastic elastomer, its rate of feeding is fast, blended effective, material plasticizing is abundant.
For achieving the above object, the utility model is achieved through the following technical solutions:
For an extruder screw for high-strength thermoplastic elastomer processing, comprise feed zone, transportation section, compression melt zone and metering homogenizing zone, described screw rod comprises some profile of tooth hybrid elements, triple screw element and three engaged elements; Described profile of tooth hybrid element, triple screw element and three engaged elements are arranged at transportation section, the compression melt zone of screw rod and measure homogenizing zone.
Preferably, described profile of tooth hybrid element is at least one in straight-tooth profile of tooth hybrid element, helical teeth profile of tooth hybrid element.
Preferably, described triple screw element is at least one in forward triple screw element, oppositely triple screw element.
Preferably, described three engaged elements are at least one in forward three engaged elements, reverse three engaged elements, neutral three engaged elements.
Preferably, described profile of tooth hybrid element is arranged at transportation section.
Preferably, described triple screw element is arranged at compression melt zone and metering homogenizing zone.
Preferably, described three engaged elements are arranged at compression melt zone.
The beneficial effects of the utility model:
Compared with prior art, the utility model combines profile of tooth hybrid element, triple screw element and three engaged elements spiral shell block element as extruder accordingly.The mixed of profile of tooth hybrid element is strong, can improve the blended effect of screw rod to material, reinforcing agent can be made fully to disperse in SEBS resin.Forward triple screw element and three engaged elements accelerate the heat transfer performance of screw rod, can make the abundant fusion plastification of material.Reverse triple screw element extends the time of staying of material in machine barrel, and material is mixed fully, is applicable to the elastomeric production field of high-strength thermoplastic.
