3D printing（3DP) be rapid shaping technique one kind, it be one kind based on mathematical model file, with powder
Shape metal or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.In at this stage, to correlation
The improvement of printing device is concentrated mainly on improvement coordinate-system, makes the position of shower nozzle more flexible accurate, or improve shower nozzle
Structure, its radiating discharging performance is improved, when finished product has color requirement, is set about from raw material, or using multiple nozzle cluster, meet to set
Count to colored or colour mixture finished product printing requirement.
But think people's shortcoming in the prior art with the presence of person skilled, for example technology can only meet at this stage
Requirement of the product to color, and the mass intensity of product depends on the mass intensity of raw material, under such present situation, is limited to product
Intensity requirement and design requirement, the production requirement of product is high, and the scope that product is suitable for is small.
The content of the invention
The purpose of this utility model is exactly that cannot concurrently reach intensity and design requirement to solve product in the prior art
The problem of.
In order to solve the above technical problems, concrete scheme of the present utility model is：
A kind of concentric extruder of particle, including the extruder head provided with outer layer material road, internal layer material road are designed, respectively with described two
Outer layer material feeding mechanism that individual material road each communicates with, internal layer feeding mechanism；In extruder head, after outer layer material road pile warp internal layer material road
In the outlet port of extruder head, two layers of concentric circle holes is formed with internal layer material road；The outer layer material feeding mechanism, internal layer feeding mechanism
Respectively include the material-extruding rod of motor driven；The material-extruding rod is in the material intracavitary of feeding element, and the feeding mouth of the material chamber is provided with material
Storehouse.
Preferably, bearing is installed in the material-extruding rod and the feeding interelement.The material-extruding rod is helical form material extrusion
Bar, the feeding element are provided with fin.The extruder head outer surface is provided with motor output shaft described in radiating groove and squeezed with described
The top of material bar is connected by shaft coupling.The feed bin is cone bucket type.The discharge outlet of the internal layer material road is in the outer layer
Inside the discharging opening of material road, the vertical interval of the discharging opening of the internal layer material road and the discharging opening of the outer layer material road is less than 3mm,
The discharging opening of the internal layer material road and the discharging opening of the outer layer material road are concentric.
The beneficial effects of the utility model are：
（1）It has devised the concentric extrusion 3D printing shower nozzle that a kind of different material forms sandwich filament by equipment, the spray
Head can ensure the toughness of printed material by internal material, ensure the intensity or color requirements of wire rod by exterior material；
（2）Inside is provided with screw feed mechanism, can prevent from expecting have bubble in material；
（3）Each feeding mechanism has independent power source, independently of one another, is easy to maintenance and adjustment, to adapt to overall production.

Embodiment
Embodiment：A kind of concentric extruder of particle, referring to Fig. 1 to Fig. 6, including provided with outer layer material road 51, internal layer material road 52
Extruder head 5, the outer layer material feeding mechanism each communicated with respectively with two material roads, internal layer feeding mechanism；In extruder head 5, outside
In the outlet port of extruder head 5 after the pile warp internal layer material road 52 of layered material road 51, two layers of concentric circle holes is formed with internal layer material road 52；Outer layer
Material feeding mechanism, internal layer feeding mechanism respectively include the material-extruding rod 33 of motor driven；Material-extruding rod 33 is in the material intracavitary of feeding element,
The feeding mouth of material chamber is provided with feed bin.In the present embodiment, further, the discharge outlet of internal layer material road 52 is in outer layer material road 51
Inside discharging opening, the vertical interval of the discharging opening of internal layer material road 52 and the discharging opening of outer layer material road 51 is 2mm, internal layer material road 52
Discharging opening and the discharging opening of outer layer material road 51 are concentric.The design can accomplish that shower nozzle discharging is interlayer structure, can ensure simultaneously
Toughness.2 millimeters of spacing can ensure that inside and outside Rotating fields have enough spaces to combine, and form stable state.
