Abstract
The utility model 3D printer quick heat radiating printhead, including feed pipe and the print-head nozzle for being arranged on feed pipe front end；The first radiator is provided with to extension on feed pipe on described print-head nozzle, coaxial sleeve is provided with air duct outside the first described radiator, and ventilation fan hole is provided with front side of described air duct, air outlet is provided with rear side of described air duct；Air-cooled fan is provided with air inlet.The utility model is due to using active heat removal, therefore efficiency is higher；And the radiator of fan blow-through first so that feed pipe is not easy to soften or melt because of overheat, simultaneously because therefore increase air duct and air guide structure do not interfere with the air-flow near 3D products yet.
Description
Technical field
3D printing technique field field is the utility model is related to, is beaten more specifically to a kind of 3D printer quick heat radiating
Print head.
Background technology
3D printing is one of embodiment of height " dimension " newest in S＆T integration body Model, alliance of Chinese Internet of Things school-run enterprise handle
It is referred to as in " thought of upper eighties of last century, the technology of eighties of last century, the market in this century ".3D printings are to use powdered gold
Category or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.The manufacture of past product makes always
The method manufacture of appliance material, that is, be machined into manufacturing, present process technology is then using the technology for adding material, i.e. 3D printing
Technology.In 3D printing technique, printing nozzle, which overheated to cause, can cause wire vent not smooth or plug wire, cause discharging uneven
It is even, influence the precision of printer model.
3D printer is that the Computerized three-dimensional data that design a model are converted into the printing utensil of physical model, and melting is heavy at present
Product Modeling Technology is the main flow printing technique of 3D printer, and the formed precision of this technology by transmission accuracy in addition to being influenceed, also one
Determine to be influenceed by feed precision in degree, because the nozzle of printhead is close away from printhead feed cavity, during material molten
High temperature is easily reached in printhead cavity by printhead shell, and as printhead cavity temperature is too high, then printed material is in printhead
Feed portion at will start to soften, feed precision is affected and then have influence on the formed precision of printer, and if
Printed material melts phenomenon because printhead high temperature produces at feed portion, then the material after melting is easy to block printhead, makes
Printer produces failure.How on the premise of printhead original function is not influenceed, improve the radiating of 3D printer printhead, be
One research direction.
The cooling that traditional 3D printer extrudes melted material to nozzle is typically carried out also by fan, and fan is fixed on nozzle
Side, its wind direction blow-through melted material, therefore fan need the shape between printhead to have angle, and printhead drives in print procedure
Fan is synchronized with the movement, and such fan design increases space hold during printhead work, in setting for collapsible 3D printer
In meter, if reducing this segment space occupancy, it can will effectively strengthen the portability of collapsible 3D printer.
For the ease of radiating, have and the shell of printhead is radiated by fan, but this radiating mode is easily formed
Radiating airflow, easily to being had an impact during the product of shaping.
Utility model content
To overcome drawbacks described above, the utility model mainly solving the technical problems that：A kind of 3D printer is provided quickly to dissipate
Thermal printer head, 3D printing head are radiated using radiating tube I and the economic benefits and social benefits of radiating tube II, good heat dissipation effect, effectively avoid and printed
A series of common bad phenomenons such as not smooth, plug of wire vent in journey, improve the precision of model.
In order to achieve the above object, the utility model 3D printer quick heat radiating printhead, including feed pipe and setting
Print-head nozzle in feed pipe front end；The first radiator is provided with to extension on feed pipe on described print-head nozzle,
The outer coaxial sleeve of the first described radiator is provided with air duct, ventilation fan hole is provided with front side of described air duct, in described air duct
Rear side is provided with air outlet；Air-cooled fan is provided with air inlet.
Preferably, the first described radiator is provided with radiating wind groove, described radiating wind groove and the air in ventilating duct
Flow to parallel.
Preferably, guide duct is provided with described air outlet.
Preferably, the second radiator, the second described radiator and are arranged at intervals with the first described radiator
One radiator is connected by heat pipe；Wherein, the evaporation ends of described heat pipe are located on the first radiator, the condensation of described heat pipe
End is arranged on the second radiator.
Preferably, described 3D printer includes：Base and the XY axles driving platform being arranged on above described base,
Column guide rail is provided between described base and XY axles driving platform；The position of nearly column guide rail is set on described base
There is drive device；Described drive device includes motor and the screw rod with motor connection, described screw rod and column guide rod
On be provided with support plate；Described radiating printhead is driven by described XY axles driving platform.
3D printer quick heat radiating printhead of the present utility model is provided with air duct, and offering fan in air duct side wall leads to
Hole, cooling fan is located at fan through hole and is directed at the first radiator, and the structure makes cooling fan, fan through hole, air duct, air-out
Mouth constitutes a complete air channel, and cool exterior air is directly blown into the first radiator by fan, and it is it to flow through the first radiator
After radiating, flowed out from air outlet, because the efficiency of active heat removal is higher and the radiator of fan blow-through first so that feed pipe is not easy
Soften or melt because of overheat, while also do not interfere with the air-flow near product.
