Abstract
The utility model belongs to the technical field of plastic processing equipment, in particular to multi -functional single screw plastic extruding machine is with extruding screw rod. This multi -functional single screw plastic extruding machine is with extruding screw rod, including the screw rod body, characterized by: be equipped with on the screw rod body by the thread sheet of tail end to head end external diameter grow in proper order, screw rod body head is equipped with the check valve, and the anterior cover of screw rod body is equipped with a lock ring, is equipped with foil between a check valve and the lock ring, and screw rod body center is equipped with the heat conduction oilhole along the axial. The beneficial effects of the utility model are that: can make the macromolecular material more even with reaction additives mixed, can make simultaneously between the raw materials misce bene abundant, make screw rod the force balance, prolong life, practice thrift the maintenance and traded a cost, improve production efficiency and product quality.
Description
(1) technical field
This utility model belongs to device of plastic processing technical field, particularly to a kind of multi-functional single-screw extruder
Use extrusion screw rod.
(2) background technology
At present, in field of high polymer material processing, plastic extruder is widely used in thin film, tubing, section bar, foaming system
Product, the processing of polymer composite and manufacture.Single screw extrusion machine is one more common in plastic extruder, but skill at present
Extrusion screw rod under art also exists more defect: extrusion screw rod rotates in barrel, and extrusion screw rod one end supports, and the other end is outstanding
Empty, and extrusion screw rod is the longest, easily deforms under self gravitation and radial force effect；Major diameter of thread is equal, it is impossible to will
Material is sufficiently mixed；Extrusion screw rod front end is cylinder, it is impossible to carry out full and uniform by raw material and reaction promoter
Mixing, affects product quality；The long-time high speed rotating of extrusion screw rod, easily damages because of heating；If extrusion screw rod is met in front end
It is easy to squeeze by material to resistance, causes blocking.
(3) summary of the invention
This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of raw material mix homogeneously, production efficiency are high, raw
Produce low cost, the multi-functional single-screw extruder extrusion screw rod of raising product quality.
This utility model is achieved by the following technical solution:
A kind of multi-functional single-screw extruder extrusion screw rod, including screw body, is characterized in that: described screw rod is originally
Body is provided with and is become big screw thread sheet successively by tail end to head end external diameter, and screw body head is provided with check (non-return) valve, and screw body is anterior
Being arranged with bracing ring, be provided with foil between check (non-return) valve and bracing ring, screw body is centrally along being axially arranged with heat conduction oilhole.
Described bracing ring is made up of internal ring and outer shroud, is connected with support bar between internal ring and outer shroud.
The beneficial effects of the utility model are: macromolecular material and reaction promoter can be made to mix evenly, can make former simultaneously
Between material, mix homogeneously is abundant, makes screw rod stress balance, extends service life, has saved maintenance and has changed part cost, having improve
Production efficiency and product quality.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model；
In figure, 1 screw body, 2 screw thread sheets, 3 check (non-return) valves, 4 bracing rings, 5 foils, 6 heat conduction oilholes, 7 internal ring, outside 8
Ring, 9 support bars.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment includes screw body 1, and screw body 1 sets
Having and become big screw thread sheet 2 successively by tail end to head end external diameter, screw body 1 head is provided with check (non-return) valve 3, the anterior set of screw body 1
Being provided with bracing ring 4, be provided with foil 5 between check (non-return) valve 3 and bracing ring 4, screw body 1 is centrally along being axially arranged with heat conduction oilhole
6.Bracing ring 4 is made up of internal ring 7 and outer shroud 8, is connected with support bar 9 between internal ring 7 and outer shroud 8.
Using multi-functional single-screw extruder extrusion screw rod of the present utility model, the external diameter of screw thread sheet 2 gradually becomes
Greatly, can make to mix between raw material full and uniform.Foil 5, at the head end of screw body 1, can make raw material mix with reaction promoter
Evenly, Improving The Quality of Products.Check (non-return) valve 3 makes raw material outwards can only extrude along screw body 1 axial direction so that extrusion
Raw material will not return, and improves production efficiency, prevents from polluting raw material.Bracing ring 4 has radial direction to screw body 1
Supporting role, prevents it from damaging because of deadweight and radial force effect, extends service life, saved maintenance and becoming of changing part
This；Raw material can pass through between internal ring 7 and outer shroud 8, and internal ring 7 and outer shroud 8 are connected as one by support bar 9.Conduction oil can be passed through
Hole 6, to screw body 1 center filling heat-conductive oil, takes away the heat that screw body 1 produces because of long-term high-speed rotation.
Claims (2)
