Specific embodiment
As shown in Figure 1, a kind of 3D printing spray head blowing-type heat removal apparatus, including ejection head unit 10, air blast heat removal apparatus
20 and raw material 30；Ejection head unit 10 includes feed pipe 11 and heater 14；The upper end of feed pipe 11 is fixed with mobile support plate 12；
The downside of feed pipe 11 is arranged in heater 14；Nozzle 15 is installed on heater 14；It is solid between heater 14 and feed pipe 11
Surely there is heat-insulating base 13；The vacuum tank 130 of annulus channel-shaped is formed inside heat-insulating base 13；It is evacuated in vacuum tank 130；Heat-insulating base
13 centers form the upper and lower perforative feed opening walked for raw material 30；Heat-insulating base 13 forms removing for several even circumferential distributions
Hot air pipeline 131；Except the upper end import of hot air pipeline 131 is located on the upper surface of heat-insulating base 13, middle part is located at vacuum tank
Between 130 and feed opening, lower end outlet be located at heat-insulating base 13 end face outside on；Air blast heat removal apparatus 20 includes that several circumference are equal
The air inlet framework 21 of even distribution；Air inlet framework 21 is fixed on the lower end surface of mobile support plate 12；It is formed in air inlet framework 21
Air reservoir 210；The outside side wall bottom of air reservoir 210 forms air inlet 211；Breather check valve is installed in air inlet 211
212；Venthole 213 is formed in the lower wall of air reservoir 210；Steam hose 22 is installed in venthole 213；Steam hose
22 upper end import is equipped with outgassing nonreturn valve 221；The lower end of steam hose 22 be mounted on the upper end except hot air pipeline 131 into
At mouthful；Lifting is provided with the stripper plate 231 cooperated with air reservoir 210 in air reservoir 210.
As shown in Figure 1, the lower horizontal except hot air pipeline 131 is arranged.
As shown in Figure 1, being fixed with several push cylinders 23 on the upper surface of mobile support plate 12；The piston of push cylinder 23

The working principle of 3D printing spray head blowing-type heat removal apparatus:
When work, due to being in vacuum in vacuum tank 130, the heat that heater 14 generates is largely isolated, but also
There is a little heat to be communicated up by feed opening, stripper plate 231 is moved up from air inlet from breather check valve 212, is then squeezed
Plate 231 moves down from steam hose 22 to except ventilating in hot air pipeline 131 and takes the heat being communicated up from feed opening out of, this
Sample prevents heat from being communicated up, and printing raw material will not soften too early, causes to block；Due to being blown afloat using air blast mode, so not having
There is vibration caused by radiator fan, does not influence print quality.
The above content is only better embodiment of the invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
