Lower end at least with first discharging syringe needle lower end be aligned, which is characterized in that further include be arranged in the first barrel outside second
Barrel and the second discharging syringe needle for being placed coaxially on the second barrel lower end, second barrel and the first barrel are coaxially disposed.
The upper end of first barrel is provided with the first feed pipe and the second feed pipe, and the demarcation plate upper end is higher than the first feed pipe
With the upper end of the second feed pipe, and the two sides of demarcation plate are arranged in the first feed pipe and the second feed pipe.The demarcation plate
Lower than the lower end of the first discharging syringe needle, the lower end of the second discharging syringe needle is lower than the lower end of demarcation plate for lower end.
Preferably, demarcation plate is arranged on the axis of the first discharging syringe needle.
Preferably, further include the first mounting plate the first barrel to be installed to printer mobile device and to by
Two barrels are installed to the second mounting plate of printer mobile device, and first barrel passes through the second mounting plate.
Preferably, fixing piece is provided between second barrel and the second mounting plate.
Compared with prior art, the invention has the following advantages:
1) print head not only may be implemented hollow printing but also solid printing may be implemented, and can satisfy some need by hollow printing
The occasion of material is saved, and some requirements for needing higher-strength can satisfy by solid printing, and then can be realized not
With the demand of occasion, it is easy to use；
2) the first barrel of the print head realizes hollow printing using demarcation plate, according to difference of the demarcation plate in the first barrel
Position can print the two sidewalls of different-thickness；And the two sides of demarcation plate are respectively arranged with a feed pipe, by two into
Expects pipe is respectively controlled, and can also print different structures.
Detailed description of the invention
Fig. 1 is cross-sectional view according to a preferred embodiment of the present invention；
Fig. 2 is the schematic diagram of demarcation plate according to a preferred embodiment of the present invention；
Fig. 3 is the schematic diagram cooperated according to the demarcation plate of a preferred embodiment of invention and the first barrel.
Specific embodiment
It is described below for disclosing the present invention so that those skilled in the art can be realized the present invention.It is excellent in being described below
Embodiment is selected to be only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
Including the first barrel 2,2 lower end of the first barrel is arranged in a kind of print head of 3D printer as shown in Figs. 1-3
First discharging syringe needle 6 and the first feed pipe 3 that 2 upper end of the first barrel is set, first barrel 2 and the first discharging syringe needle 6
Coaxial arrangement, the first discharging syringe needle 6 is tapered, and molten metal material enters in the first barrel 2 from the first feed pipe 3
And it is flowed out from the first discharging syringe needle 6 and then realizes 3D printing.
The demarcation plate 5 axially extended is provided in the first barrel 2, the two sides of the demarcation plate 5 at least go out with first
The inner wall of material pin head 6 is fixedly connected, and the lower end of the demarcation plate 5 is at least aligned with the lower end of the first discharging syringe needle 6, can also be omited
Micro stretching goes out the first discharging syringe needle 6.The upper end of the demarcation plate 5 can be extend into the first barrel 2, and worked as and extend into the first material
When in cylinder 2, the two sides of the demarcation plate 5 are fixedly connected with the inner wall of the first barrel 2 to increase the fastness of demarcation plate 5.Pass through
Demarcation plate can will be divided into twice from the first metal for flowing out of discharging syringe needle 6, and the middle part of twice does not have metal, that is, realize
Impact missing print.
Further, control the metal flow of 5 two sides of demarcation plate for convenience, the upper end of the demarcation plate 5 be higher than first into
Topmost, the side opposite with the first feed pipe 3 is provided with third feed pipe 31, and then realization pair to expects pipe 3 on the first barrel 2
The metal flow of 5 two sides of demarcation plate in first barrel 2 is respectively controlled.
Further, the demarcation plate 5 can be located on the axis of the first discharging syringe needle 6, the knot for the two sides printed at this time
Structure is of same size, can not also be located on the axis of the first discharging syringe needle 6, the structure width for the two sides printed at this time is different.
The print head further includes the second barrel 11 with the coaxial arrangement of the first barrel 2, the lower end of second barrel 11
It is provided with the second coaxial discharging syringe needle 12, the second discharging syringe needle 12 is tapered.The first discharging syringe needle 6 is arranged
It is lower than the lower end of the first discharging syringe needle 6 in the lower end of the inside of the second discharging syringe needle 12, and the second discharging syringe needle 12, and is lower than
The lower end of demarcation plate 5 will not be separated with guaranteeing to melt when metal is flowed out from the lower end of the second discharging syringe needle 12, and then can be beaten
Print off solid structure.The upside of second barrel 11 is provided with the second feed pipe 10, melts metal from the second feed pipe
10 enter in the second barrel 11 and flow out from the lower end of the second discharging syringe needle 12.
In order to facilitate fixation, the upper end of the first barrel 2 is higher than the upper end of the second barrel 11, and the first feed pipe 3 and the
Three feed pipes 31 are fixedly connected with and are located at the top of the second barrel 11 with the first barrel 2.
The upper end of first barrel 2 is fixed on the first mounting plate 1, and the upper end of second barrel 11 is fixed to second
On mounting plate 9, first barrel 2 is passed through from the center of the second mounting plate 9, and the first barrel 2 passes through fixing piece 7 and second
Mounting plate 9 is fixedly connected to realize the relatively fixed of the first barrel 2 and the second barrel 11.
Further, in order to facilitate the installation of, the upper end of demarcation plate 5 can be directly aligned with the upper end of the second barrel 11, in turn
Since the barrier effect of the first mounting plate 9 prevents the two sides of demarcation plate 5 from mutually circulating, the convenient technology flow to two sides into
Row control.
First feed pipe 3, third feed pipe 31 and second feed pipe 2 respectively with the metal melt on printer
Which feed pipe device connection, printer can control molten metal by the circulation of control pipeline.Meanwhile first
Mounting plate 1 and the second mounting plate 2 are mounted in the mobile device of printer, and printer can be controlled by control mobile device and be beaten
