Abstract
A kind of 3D printer ejecting device of the present invention, there is the charging inclined-plane in constant slope with nozzle body in nozzle upper end, with the limitation to a plurality of shape feed inlet width on charging inclined-plane so that the nozzle diameter of fine nozzle is more than a plurality of shape feed inlet width on charging inclined-plane.Change the existing 3D printer nozzle fine because nozzle is equipped with, and the situation that the particulate contamination retained in Filamentous heat-fusible materials blocks.After Filamentous heat-fusible materials can be allowed to heat, into nozzle cavity, ejection material is squeezed by the nozzle of minute nozzle, and greater than, equal to the particulate contamination of spray nozzle diameter, then it is trapped within outside strip feed inlet.
Description
Technical field
The present invention relates to RP technique fields, and in particular to a kind of 3D printer ejecting device.
Background technology
3D printer is a kind of based on digital model file, with adhesive materials such as plastics, by successively printing
Mode carry out the technology of constructed object.
Just gradually it is being widely used for primary mold manufacture, some products of the industrial circles such as mold manufacturing, industrial design
Directly manufacture；Just gradually applied to the realization of the consciousness of DIY and duplication of toy etc..
Existing 3D printer technology contents mainly by：Input Software data command manipulates 3D printer, by Filamentous heat
Melt material heating and melting is squeezed there are one the nozzle of minute nozzle by band and gushed out.It is sprayed after hot melt material fusing from nozzle,
It is deposited on print job deck plate or preceding layer oneself cured material, temperature starts to cure after being less than solidification temperature, passes through
The layer upon layer of material forms final finished.
The advantage of 3D printer is to be simple to manufacture, and operation and maintenance are cheap into wood, but current 3D printer is generally deposited
In a very big defect, the sale of 3D printer is directly affected with popularizing.
Squeeze out nozzle component blockage problem：
People accept substantially, and the common wire leading pipe of 3D printer is made of metal material, and wire leading pipe one end (wire outlet end) connects
Heating element and nozzle are connect, since metal is the good conductor of heat, the wire inlet end temperature for leading to wire leading pipe is excessively high, and fuse is caused to lead
Soften in fiber tube, result in blockage and can not continue into silk, eventually lead to printing and interrupt.
So technological improvement insulation bushing guiding, the active force of heating element and nozzle segment is increased to, but, spray
Head blockage problem still remains.
The basic reason that 3D printer nozzle blocks is：Filamentous heat-fusible materials heating and melting, by band, there are one micro-
The nozzle of thin nozzle squeezes the process to gush out.
When being processed to filiform, 1. the technique by raw material shape becomes Filamentous heat-fusible materials --- heat-fusible materials
More, in manufacturing process is heated, in the material mixing addition of hot melt manufacture, it is mingled with particulate contamination with can not avoiding,
Particulate inclusions diameter is different.
2. the nozzle of minute nozzle squeezes ejection material --- in order to reach higher precision, 3D printer nozzle is equipped with fine
The nozzle of nozzle, the working condition of fine nozzle and the retention particulate contamination in Filamentous heat-fusible materials are forever inevitable
Ground is in the blocking for forming 3D printer nozzle.
Nozzle again and again blocks, so that occurring the special tool of special dredging 3D printer nozzle in Taobao
Tool has directly been raised and 3D printer has been required using the profession of technical staff so that since the Technical comparing being related to is complicated, safeguards
Cost increases, and application range also just can only narrowly concentrate on high-end manufacturing field.
Invention content
In view of the deficiencies in the prior art, the present invention proposes a set of solution, provides a kind of 3D printer ejecting device.
Technical solution is as follows：
A kind of content described in 3D printer ejecting device includes：Have in nozzle upper end with nozzle body in constant slope
Inclined-plane is fed, feeding on inclined-plane has a plurality of shape feed inlet；There are the holes penetrated through with nozzle cavity at nozzle threaded upper ends.
Beneficial effects of the present invention：
The present invention is with the limitation to a plurality of shape feed inlet width on charging inclined-plane so that the nozzle diameter of fine nozzle is big
A plurality of shape feed inlet width on charging inclined-plane, after Filamentous heat-fusible materials can be allowed to heat, into nozzle cavity, by fine
The nozzle of nozzle squeezes ejection material, and greater than, equal to the particulate contamination of spray nozzle diameter, then it is trapped within strip feed inlet
Outside.
Angle rational design of the strip feed inlet on charging inclined-plane ensure that Filamentous heat-fusible materials flowing and squeeze out and make
Firmly transmit.
Inclined-plane is fed effectively to resting on the retention particulate contamination in strip feed inlet heat-fusible materials, because by filiform
Heat-fusible materials extrusion power, and be eliminated and move.
There are the holes penetrated through with nozzle cavity at nozzle threaded upper ends, can reduce welding nozzle upper end and charging inclined-plane
When technological requirement, and disclosure satisfy that the clean requirement of finished product of nozzle cavity part.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing 1, Fig. 2, Fig. 3,
Fig. 4, the present invention will be described in further detail.
A kind of 3D printer ejecting device has oblique in the charging of constant slope with nozzle body in nozzle body (1) upper end
Face (3), feeding on inclined-plane (3) has a plurality of shape feed inlet (6)；At nozzle body (1) threaded upper ends (2) there are with nozzle cavity
(8) cleaning hole (4) of perforation.
The width of a plurality of shape feed inlet (6) on inclined-plane (3) is fed, it is straight less than nozzle body (1) lower end nozzle (5)
Diameter after Filamentous heat-fusible materials heat, is flowed into nozzle cavity (8), by fine in nozzle body (1) by extrusion power
Nozzle (5), which squeezes, sprays material.
In Filamentous heat-fusible materials, greater than, equal to the particulate contamination of spray nozzle (5) diameter, then it is trapped within strip
Feed inlet (6) is outside.
Angle of the strip feed inlet (6) in charging inclined-plane (3) is rational design, ensure that Filamentous heat-fusible materials hot melt
Mobility direction coincide afterwards transmits with extrusion power.
By by Filamentous heat-fusible materials extrusion power, feeding and resting on the heat at strip feed inlet (6) on inclined-plane (3)
Particulate contamination is retained in melt material, is eliminated and moves.
There is the cleaning hole (4) with nozzle cavity (8) perforation at nozzle body (1) threaded upper ends (2), by more times of diameter
The cleaning hole (4) of number and nozzle (5) diameter, technique when can reduce welding nozzle body (1) upper end with feeding inclined-plane (3) will
It asks, and disclosure satisfy that the clean requirement to finished product nozzle body (1) upper nozzle inner cavity (8) part.
, there is polyhedron nut shape (7) in screw thread (2) lower end in nozzle body (1), convenient for by nozzle body (1) and 3D printing
Thermomechanical components screw thread coincide fixation.
Since screw thread (2) and 3D printer component screw thread coincide fixation in nozzle body (1), cleaning hole (4) is closed, nozzle
Inner cavity (8) enclosure space is set up.
In this description, the present invention oneself be described with reference to its specific embodiment.But it is clear that it can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
