Abstract
The utility model provides a kind of Novel polypropylene screw for extruder structure, comprise and be arranged at screw body in machine barrel and screw head, screw body comprises feed zone, fluxing zone and extruding zone, be provided with between fluxing zone and extruding zone and return plastifying organization, described extruding zone is provided with homogenizing zone.The described plastifying organization that returns comprises some grooves being arranged on screw surface and the round bar nail be arranged in groove, leaves material and extrude gap between round bar nail and groove.Described fluxing zone is divided into preliminary fluxing zone, again fluxing zone, and fluxing zone is arranged on the right side returning plastifying organization again, and it is provided with backpitch spiral shell rib near the side returning plastifying organization.The utility model well can plastify and homogenizing material, improves products obtained therefrom quality.
Description
Technical field
The utility model relates to a kind of screw-rod structure, particularly a kind of Novel polypropylene screw for extruder structure.
Background technology
Injection screw presses it to the adaptability of plastics, Universal screw rod and special screw rod can be divided into, Universal screw rod is also known as conventional screw, the thermoplastic that major part has low, middle viscosity can be processed, the civilian plastics of crystal type and non-crystalline type and engineering plastics, be the most basic form of screw rod, its corresponding also have special screw rod, is used to the unmanageable plastics of processing common screw; By screw-rod structure and geometric characteristic thereof, can be divided into conventional screw and new screw, conventional screw is also called three-stage screw, is the citation form of screw rod, new screw form then has a variety of, as separating screw rod, bypass type screw rod, wavy screw rod, without metering section screw rod etc.
Mostly existing polypropylene screw for extruder structure, be to be made up of the spiral shell rib in simple screw surface, in the process of extruded material, no matter the plasticizing of material and homogenizing whether complete, material is directly sent by it, causes products obtained therefrom quality not to be guaranteed.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Novel polypropylene screw for extruder structure, solves existing screw-rod structure and can not plastify material and the technical problem of homogenizing.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel polypropylene screw for extruder structure, comprise and be arranged at screw body in machine barrel and screw head, screw body comprises feed zone, fluxing zone and extruding zone, be provided with between fluxing zone and extruding zone and return plastifying organization, described extruding zone is provided with homogenizing zone.
Preferably, described in return plastifying organization and comprise some grooves being arranged on screw surface and the round bar nail be arranged in groove, leave material between round bar nail and groove and extrude gap.
Preferably, described fluxing zone is divided into preliminary fluxing zone, again fluxing zone, and fluxing zone is arranged on the right side returning plastifying organization again, and it is provided with backpitch spiral shell rib near the side returning plastifying organization.
Preferably, described homogenizing zone is made up of some circle projections of screw surface, and homogenizing zone comprises the first homogenizing zone and the second homogenizing zone.
Good effect of the present utility model: first-selected, the utility model is provided with and returns plastifying organization, when mixed material is after preliminary plasticizing, plastify underproof material under the effect returning plastifying organization, to be back to fluxing zone again again to plastify, until plastify qualified till, and the setting of homogenizing zone ensure that plasticizing qualified after material well carry out homogenizing, to ensure products obtained therefrom quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel polypropylene screw for extruder of the utility model structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
With reference to Fig. 1, the utility model preferred embodiment provides a kind of Novel polypropylene screw for extruder structure, comprise and be arranged at screw body in machine barrel and screw head, screw body comprises feed zone 1, fluxing zone and extruding zone 5, be provided with between fluxing zone and extruding zone 5 and return plastifying organization 4, described extruding zone is provided with homogenizing zone.
The described plastifying organization 4 that returns comprises some grooves being arranged on screw surface and the round bar nail 8 be arranged in groove, leaves material and extrude gap between round bar nail 8 and groove.
Described fluxing zone is divided into preliminary fluxing zone 2, again fluxing zone 3, and fluxing zone 3 is arranged on the right side returning plastifying organization 4 again, and it is provided with backpitch spiral shell rib 9 near the side returning plastifying organization 4.
Described homogenizing zone is made up of some circle projections 10 of screw surface, and homogenizing zone comprises the first homogenizing zone 6 and the second homogenizing zone 7.
When using the utility model, mixed material enters into screw mechanism through feed zone, plastify through preliminary fluxing zone, plastify qualified material and be extruded into discharging section through the gap between round bar nail and groove, plastify underproof material to be back to again fluxing zone and to carry out secondary plasticizing under the effect of round bar nail and backpitch spiral shell rib, plastify qualified after be extruded into extruding zone again, material is extruded after a homogenizing and secondary homogenizing at extruding zone, and products obtained therefrom quality obtains obvious lifting.
Above-describedly be only preferred embodiment of the present utility model; be understood that; the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; and be not used in restriction protection domain of the present utility model; all any amendments, equivalent replacement etc. made within thought of the present utility model and principle, all should be included within protection domain of the present utility model.
