Description
Technical field
The present invention relates to the 3D printing technique fields of material extrusion molding, and in particular to one kind can be used for material extrusion molding
From rolling 3D printing integrate ejecting device.
Background technique
3D printing technique refers to print head under program, carries out material filling system according to the cross section information of current layer
It makes, then quickly produces required part by adding up layer by layer again, since it can manufacture arbitrarily complicated part and possess preferably
Printing freedom degree, in industrial production and daily life increasingly have practical application value.
Extrusion molding 3D printing at present is still vital a kind of Method of printing in 3D printing field, especially for
The light structural material such as plastics, extrusion molding are even more the printing type for being difficult to substitute within some time.And extrusion molding 3D printing
Also it can prepare that material ranges are wide, can partially prepare the build-in attribute that material has lightweight high intensity because it has, because obtaining
Application favor comprising various industries such as robot field, aerospace field, military affairs, medical treatment.Therefore, it much studies and sends out
The bright basic print performance for being dedicated to promoting extrusion molding 3D printing components.Because lot of domestic and international research was created once
The outstanding too short fiber prepreg stain of the property made, continuous fiber etc. are a variety of to make the Method of printings and material that performance equipment is promoted in single layer
It improves.However, the weak link of printout has also shown in succession to be come out while performance is obviously improved in a part of layer:
One, Coating combination performance is poor so that extrusion molding 3D printing part is still difficult to popularize in relevant application field
Using, and this weak link even is difficult to fit through continuous fiber printing or staple fiber pre-preg in many cases and
Intensity is printed in the layer significantly improved.
Two, traditional extrusion molding printing nozzle generates pole only for print surface while material extrusion molding
Small surface pressing, therefore Coating combination performance can not be both promoted by effective pressurization, even more it cannot be guaranteed that printout it is whole
Body bulk density and multiple interface performance, and this is also that the 3D printing of extrusion molding proposes an intractable problem.
Summary of the invention
In order to overcome deficiency present in the above technology, it can be used for material the purpose of the present invention is to provide one kind and be extruded into
Shape integrates ejecting device from rolling 3D printing, preferably can carry out interlayer performance and each interface performance improvement to forming face.
In order to achieve the above object, the present invention adopts the following technical scheme that:
It is a kind of to can be used for spraying from the integrated ejecting device of rolling 3D printing, including printing nozzle 4, printing for material extrusion molding
Mouth 4 is fixed on the tip external of nozzle housing 1 by nozzle fixing bolt 6, and the taper inner of nozzle housing 1 is equipped with ball 3, ball
The top of pearl 3 and the lower end of spring 2 connect, and the upper end of spring 2 and positioning bolt 5 connect, and positioning bolt 5 is mounted on outside spray head
Internal thread hole cooperation inside the inner upper end of shell 1, positioning bolt 5 and nozzle housing 1, ball 3 are limited by spring 2 in spray head
At the tip of shell 1, guarantee the rotation of ball 3.
The upper end of the nozzle housing 1 is ball entrance 101, and the tip external of nozzle housing 1 is equipped with the fixed spiral shell of nozzle
Pit 103 and material input hole 102 in communication, printing nozzle 4 are fixed on the fixed spiral shell of nozzle by nozzle fixing bolt 6
In pit 103, nozzle fixing bolt 6 is located in the material input hole 102 of nozzle housing 1.
The nozzle fixing screwed hole 402 that 4 top of printing nozzle is equipped with and nozzle fixing bolt 6 connects, lower part is set
There is material delivery outlet 401.
Described can be used for being passed through from the integrated ejecting device of rolling 3D printing when in molten condition for material extrusion molding
After printed material, printed material is squeezed out by material input hole 102, nozzle fixing bolt 6 and material delivery outlet 401, using
The extruding of ball 3 is reinforced, and by adjusting the positioning bolt 5 of different height, can change the elastic force of spring 2, thus according to material
And demand difference makes ball 3 obtain the effect of different size of extruding force.
The invention has the benefit that
The present invention can implement servo-actuated rolling by adding ball 3 on one side in printing nozzle 4, to effectively improve extrusion
Coating combination performance, print density and the every interface performance for shaping 3D printing, have traditional prints spray head and greatly change
Into and performance boost, have very big influence and meaning for the 3D printing of extrusion molding material.
Detailed description of the invention
Fig. 1 is apparatus of the present invention print procedure schematic diagram.
Fig. 2 be apparatus of the present invention fractionation after schematic diagram.
Fig. 3 is the sectional view of apparatus of the present invention.
Fig. 4 is the sectional view of nozzle housing 1.

Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
Referring to Figures 1 and 2, a kind of 3D printing of rolling certainly can be used for material extrusion molding integrates ejecting device, including beats
Print nozzle 4, printing nozzle 4 is fixed on the tip external of nozzle housing 1 by nozzle fixing bolt 6, in the tip of nozzle housing 1
Portion is equipped with ball 3, and the top of ball 3 and the lower end of spring 2 connect, and the upper end of spring 2 and positioning bolt 5 connect, positioning bolt 5
It is mounted on the inner upper end of nozzle housing 1, the internal thread hole cooperation inside positioning bolt 5 and nozzle housing 1, ball 3 passes through bullet
Spring 2 limits at the tip of nozzle housing 1, guarantees the rotation of ball 3, and spring 2 is then by positioning bolt 5 and nozzle housing 1
The cooperation of upper internal thread hole limits between positioning bolt 5 and ball 3.
Referring to Fig. 3 and Fig. 4, the upper end of the nozzle housing 1 is ball entrance 101, and the tip external of nozzle housing 1 is set
There are nozzle fixing screwed hole 103 and material input hole 102 in communication, printing nozzle 4 is fixed on by nozzle fixing bolt 6
