Abstract
The utility model belongs to the technical field of plastic processing equipment, in particular to single screw plastic exdruder. This single screw plastic exdruder including extruding a section of thick bamboo, extrudes to be equipped with in the section of thick bamboo and extrudes the screw rod, extrudes section of thick bamboo one side and is equipped with hopper, characterized by: extruding the screw rod and comprising an extrusion section and the 2nd extrusion section of a plurality of group interval arrangement, an extrusion section diameter is greater than the 2nd extrusion section diameter, is equipped with on the 2nd extrusion section to move the stirring pin, extrudes an inner wall and is equipped with and decides the stirring pin, extrudes and is equipped with a plurality of rings of heating pipes between an outer wall and the inner wall, extrude a section of thick bamboo in the intercommunication have the blast pipe. The beneficial effects of the utility model are that: can make the macromolecular material more even with reaction additives mixed, can make the bold raw materials thoroughly scatter, can carry out the stoving and the exhaust -gas disposal of moisture extruding the in -process, the raw materials misce bene, production efficiency is high, and low in production cost has improved product quality.
Description
(1) technical field
This utility model belongs to device of plastic processing technical field, particularly to a kind of single-screw extruder.
(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, also exists relatively
Many defects: only have a compression ratio；The shearing dispersibility of screw rod is poor, it is impossible to big caking materials is scattered；That extrudes is former
Material, containing substantial amounts of moisture, must continue drying and could be used for producing, reduce production efficiency, add production cost；Cannot
Unnecessary gas is discharged, causes the Quality Down of product.
(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 single-screw extruder of raising product quality.
This utility model is achieved by the following technical solution:
A kind of single-screw extruder, including extruded tube, is provided with extrusion screw rod in extruded tube, extruded tube side is provided with material
Bucket, is characterized in that: described extrusion screw rod is made up of some groups of spaced first extruding zones and the second extruding zone, the first extrusion
Section diameter is more than the second extruding zone diameter, and the second extruding zone is provided with dynamic stirring pin, and extruded tube inwall is provided with determines stirring pin,
It is provided with some circles between extruded tube outer wall and inwall and adds heat pipe, in extruded tube, be communicated with exhaustor.
Described exhaustor connects induced-draught fan.
Described extrusion screw rod connects has reductor, reductor to be connected with motor.
The beneficial effects of the utility model are: macromolecular material and reaction promoter can be made to mix evenly, bulk can be made former
Material thoroughly scatters, and can carry out drying and the pump-down process of moisture, raw material mix homogeneously in extrusion, and production efficiency is high,
Production cost is low, improves 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 extruded tube, 2 extrusion screw rods, 3 hoppers, 4 first extruding zones, 5 second extruding zones, 6 dynamic stirring pins, 7 is fixed
Stirring pin, 8 add heat pipe, 9 exhaustors, 10 induced-draught fans, 11 reductors, 12 motors.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment includes extruded tube 1, is provided with crowded in extruded tube 1
Going out screw rod 2, extruded tube 1 side is provided with hopper 3, and extrusion screw rod 2 is by some groups of spaced first extruding zone 4 and the second extrusions
Section 5 is constituted, and the first extruding zone 4 diameter is more than the second extruding zone 5 diameter, and the second extruding zone 5 is provided with dynamic stirring pin 6, extrusion
Cylinder 1 inwall is provided with determines stirring pin 7, is provided with some circles and adds heat pipe 8, be communicated with in extruded tube 1 between extruded tube 1 outer wall and inwall
Exhaustor 9.Exhaustor 9 connects induced-draught fan 10.Extrusion screw rod 2 connects has reductor 11, reductor 11 to be connected with motor 12.
Use a kind of single-screw extruder of the present utility model, raw material is sent into hopper 3, starts motor 12, motor
12 drive reductors 11 thus drive extrusion screw rod 2 to rotate and then extruded material.Extrusion screw rod 2 is by the first extruding zone 4 and second
Extruding zone 5 interval is constituted, and macromolecular material and reaction promoter can be made to mix evenly；Move stirring pin 6 and stirring pin 7 can surely
Rotate the shearing force that the raw material simultaneously moved ahead is certain, bulk materials can be made to scatter thoroughly, it is simple to mixing and homogeneous heating, carry
High product quality.Can heat to raw material by adding heat pipe 8 in extrusion, remove the moisture in plastic raw materials, carry
High production efficiency, reduces production cost.Start induced-draught fan 10, can be dried adding heat pipe 8 in extruded tube 1 by exhaustor 9
The excessive gas of generation is discharged during moisture etc., improves the quality of product.
