Description
Technical field
The present invention relates to printer field, and in particular to a kind of 3D printer consumptive material shower nozzle with cooling device.
Background technology
The 3D printer difference maximum with conventional printer is that " ink " that it is used is raw material true, heap
The form of folded thin layer has varied, available for the medium wide variety of printing, from various plastics to metal, ceramics and rubber
Gelatin substance.Some printers can also combine different medium, and one, the object that order is printed is hard and other end is soft.
Some 3D printers use the mode of " ink-jet ".Printer head is used by one layer of very thin liquid plastic material
It is sprayed on mold pallet, this coating is then placed in being handled under ultraviolet.Mold pallet declines minimum distance afterwards,
So that next layer of stacking is come up.
Use one kind also is called the technology of " fused deposition modeling ", and whole flow process is that plastics are melted in shower nozzle, Ran Houtong
The mode for crossing depositing plastic material fiber just forms thin layer.
Also some systems are called the technology of " laser sintered " using one kind, and print media is used as using powder particle.Powder
Particulate is sprayed one layer of very thin powder bed of formation on mold pallet, and then founding is glued into designated shape by the liquid sprayed
Mixture is solidified.
What is had is then to utilize the electron stream fusing powder particle in vacuum, and complexity as hole and cantilever is included when running into
Addition gel or other materials are accomplished by during structure, in medium to support or for taking up space to provide.This amount of powder is not
Can be by founding, it is last that only need to fall supporter with water or gas washout just can form hole.
But, above-mentioned used consumptive material is required to heat treatment, forms the consumptive material of molten state, and its cooling is slower, easily
Occurs the deformation in cooling procedure.
The content of the invention
Based on solving the above problems, the invention provides a kind of 3D printer consumptive material shower nozzle with cooling device, including：
Conduit, include being used for from inside to outside successively consumptive material used in importing the first pipeline, for heat the consumptive material the
Two pipelines and the 3rd pipeline for importing cooling gas, the conduit bottom have the dividing plate for closing the conduit, described
There is first connector and multiple second connectors on dividing plate；
One nozzle, for exporting the consumptive material, below the dividing plate and with the body of cylinder, the nozzle leads to
Cross the connector and be connected to first pipeline；
One or more gas output tubes, it is one or more of below the dividing plate and with the body of cylinder
Gas output tube is connected to the 3rd pipeline by the multiple second connector.
Embodiments in accordance with the present invention, the cooling gas can be nitrogen, argon gas or air.
Embodiments in accordance with the present invention, the diameter of the body of the nozzle is less than the diameter of first pipeline.
Embodiments in accordance with the present invention, when one or more of gas output tubes are multiple, the multiple gas output
Pipe is uniformly distributed on using the center of the first connector as the circular arc in the center of circle.
Embodiments in accordance with the present invention, when one or more of gas output tubes are one, one gas output
Manage the pipe for circular shape or the pipe of fan shape.
Embodiments in accordance with the present invention, the bore of second connector is less than one or more of gas output tubes
Caliber.
According to the present invention, a kind of application method of 3D printer consumptive material shower nozzle is additionally provided, it is using above-mentioned with cold
But the 3D printer consumptive material shower nozzle of device, comprises the following steps：When normal print uses consumptive material, consumptive material is sprayed by nozzle and carried out
Print job, consumptive material temperature now is higher, then using the cooling gas of gas output tube, and the high temperature consumptive material of ejection is carried out
Cooling.
Advantages of the present invention is as follows：
（1）3rd pipeline can isolate the heat of the second pipeline, prevent heat from being transmitted to other printer units, anti-to stop loss
Evil miscellaneous part；
（2）Cooling device can cooling down high-temperature consumptive material rapidly, the bore controlled wind speed of connector can be utilized, deformation is prevented.
Brief description of the drawings
Fig. 1 is the sectional view of the 3D printer consumptive material shower nozzle with cooling device of the present invention；
Fig. 2 is the top view of another gas output tube of the present invention；
Fig. 3 is the top view of the another gas output tube of the present invention.
Embodiment
Referring to Fig. 1, the 3D printer consumptive material shower nozzle 100 with cooling device of the invention, including：
Conduit, include being used for from inside to outside successively consumptive material used in importing the first pipeline 1, for heat the consumptive material the
Two pipelines 2 and the 3rd pipeline 3 for importing cooling gas, the conduit bottom have the dividing plate for closing the conduit, institute
Stating has first connector 7 and multiple second connectors 6 on dividing plate；
One nozzle 4, for exporting the consumptive material, below the dividing plate and with the body of cylinder, the nozzle 4
First pipeline 1 is communicated in by first connector 7；
Multiple gas output tubes 5, for exporting the cooling gas, below the dividing plate and with the pipe of cylinder
Body, the multiple gas output tube 5 is communicated in the 3rd pipeline 3 by the multiple second connector 6.The cooling gas
