Abstract
This utility model embodiment discloses a kind of double screw extruder making PET resin plastify completely, including extrusion cylinder, closely rotate extrusion screw rod, the mould being arranged in described extrusion cylinder and be arranged at the air deflector between described mould and described extrusion cylinder, described screw rod end is coniform, and top is round and smooth, described air deflector has honeycomb duct, described honeycomb duct one end is that circular cone connection chamber is sheathed on described screw rod end, and it is round and smooth excessively with described honeycomb duct that described circular cone connects chamber.Use this utility model, prevent the glue under molten condition from forming stationary stream district at screw rod end by air deflector, make glue keep overall sufficiently mobility in extruding progradation, keep the quality of product formation, and reduce the trouble of production maintenance, improve production efficiency.
Description
Technical field
This utility model relates to a kind of extruder, particularly relates to a kind of double screw extruder making PET resin plastify completely.
Background technology
In existing double screw extruder, use screw rod that masterbatch is extruded, make masterbatch form mixing molten
State, and push and be squeezed in mould being able to extruded, but in the process, screw rod is after using certain time, female
Expecting that rotated screw rod transmission arrives the head end of screw rod, this end is tapered, and the inclined-plane of termination is less, and napex is pointed,
There is flow resistance formation stagnation district in sizing material herein, under long duration of action, continues to increase, and sizing material produces and decomposes or resolve thing,
Cause plastifying, affect the quality of product, and there is the trouble of cleaning.
Summary of the invention
This utility model embodiment technical problem to be solved is, it is provided that a kind of make that PET resin plastifies completely double
Screw extruder.Can prevent sizing material from advancing end generation stationary stream district to produce decomposition.
In order to solve above-mentioned technical problem, this utility model embodiment provide a kind of make that PET resin plastifies completely double
Screw extruder, is arranged at extrusion screw rod, the mould in described extrusion cylinder including extrusion cylinder, closely rotation and is arranged at described
Air deflector between mould and described extrusion cylinder, described screw rod end is coniform, and top is round and smooth, and described air deflector has leads
Runner, described honeycomb duct one end is that circular cone connection chamber is sheathed on described screw rod end, and described circular cone connects chamber and described honeycomb duct
Round and smooth excessively.
Wherein, described air deflector is provided with the joint face indent of described mould and is connected chamber, and described connection intracavity is provided with
Bore conversion head.
Implement this utility model embodiment, have the advantages that this utility model prevents molten by air deflector
Glue under state forms stationary stream district at screw rod end, makes glue keep overall sufficiently mobility in extruding progradation, protects
Hold the quality of product formation, and reduce the trouble of production maintenance, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type is described in further detail.
With reference to the overall structure schematic diagram of the present utility model shown in Fig. 1.
A kind of double screw extruder making PET resin plastify completely of this utility model embodiment, including extrusion cylinder 10, squeezes
Go out screw rod 11, mould 20, air deflector 30.
Extrusion screw rod 11 closely rotates and is arranged at extrusion cylinder 10 inside, and extrusion screw rod end 12, in coniform, has bigger
Gradient, and top is round and smooth.
Air deflector 30 has honeycomb duct 31, and honeycomb duct 31 coordinates with extrusion screw rod 11 one end to be provided with circular cone and is connected chamber 32,
Circular cone connects chamber 32 and is sheathed on extrusion screw rod end.
It is round and smooth excessively with honeycomb duct 31 that circular cone connects chamber 32, makes glue flowing have good fluency.
Air deflector 30 is provided with the joint face indent of mould 20 and is connected chamber 33, is provided with bore conversion head in connecting chamber 33
34, 'go'gage conversion head 34 can change, according to the size of different moulds 20, the bore conversion head being suitable for, and improves the suitability.
This utility model embodiment forms the runner less than screw diameter by air deflector at screw rod end, makes screw rod end
Sizing material advances in mould swimmingly, prevents stagnant area, is applicable to different moulds additionally by bore transducer, improves
Practicality of the present utility model.
Certainly above-described embodiment is only for illustrating technology of the present utility model design and feature, its object is to allow and is familiar with this
The people of technology will appreciate that content of the present utility model and implements according to this, can not limit protection model of the present utility model with this
Enclose.All modifications done according to the spirit of this utility model main technical schemes, all should contain guarantor of the present utility model
Within the scope of protecting.
