Line is configured the Teflon pipe 113 being located in trunnion.
The defect of the printer head is that the feed end of trunnion is longer than the feed end of Teflon pipe, and without fin,
The radiating effect of trunnion is bad, be able to may soften when consumptive material enters trunnion and is introduced into Teflon pipe, or consumptive material does not have also
It is just softened when having into trunnion, so that can not normal print.
In the prior art, also there are some 3D printer shower nozzles to be provided with fin, but Teflon is not put into trunnion
The Teflon pipe length managed or be put into is very short, and the Teflon pipe being put into is only just identical with the length of trunnion.When dissipating for fin
When thermal effect is not good enough, it can cause consumptive material in trunnion or also just not softened into trunnion, and normal condition is consumptive material
Just start softening after into heat block, soften in advance, machine can be caused to be unable to normal print, or even shower nozzle can be blocked.
Utility model content
In order to overcome the shortcomings of that above-mentioned prior art is present, main purpose of the present utility model is that providing one kind prevents consumption
The 3D printer shower nozzle that material softens in advance.
To achieve these goals, the utility model specifically uses following technical scheme：
This practicality newly provides a kind of ejecting device of 3D printer, including nozzle, trunnion, heat block, fin and first
Teflon pipe, the discharge end of the trunnion is connected with the feed end of the nozzle, and the heat block is coated on the nozzle and institute
The junction of trunnion is stated, the fin is coated on the feed end of the trunnion, and first Teflon pipe is arranged at the larynx
In pipe, and the discharge end of first Teflon pipe is used to convey consumptive material, the charging of first Teflon pipe to the nozzle
End passes the feed end of the trunnion.
Preferably, the feed end of the trunnion passes the feed end of the fin.
The length that the feed end of first Teflon pipe passes the feed end of the trunnion is 20mm -100mm.
Preferably, first Teflon pipe is coaxially disposed with the trunnion.
Preferably, the wall thickness in the middle part of the trunnion is less than the wall thickness at the trunnion two ends.
Preferably, the heat block is threadedly coupled with the discharge end of the trunnion and the feed end of the nozzle respectively.
Preferably, the fin is threadedly coupled with the feed end of the trunnion.
In addition, the utility model also provides and a kind of includes the 3D printer of ejecting device described above.
The new 3D printer ejecting device of this practicality includes nozzle, trunnion, heat block, fin and the first Teflon pipe,
The discharge end of the trunnion is connected with the feed end of the nozzle, and the heat block is coated on the company of the nozzle and the trunnion
Place is met, the fin is coated on the feed end of the trunnion, and first Teflon pipe is arranged in the trunnion, and described
The feed end of first Teflon pipe is used to convey consumptive material to the nozzle, and the feed end of first Teflon pipe passes the larynx
The feed end of pipe.
Compared to prior art, the utility model is provided with the fin for being coated on trunnion feed end outer surface, makes trunnion
Heat can scatter away as soon as possible.The first Teflon pipe is arranged in trunnion simultaneously, and make the discharge end of the first Teflon pipe with
Nozzle is connected, and the feed end of the first Teflon pipe passes the feed end of trunnion, realizes integral type charging.It is resistance to using Teflon pipe
High temperature, low-friction coefficient, resistance to bond and ageing-resistant advantage, reduce the friction of consumptive material and trunnion and fin, make charging more
It is smooth, improve pushing precision during printing；But also heat-insulated effect can be played, prevent consumptive material from beginning in trunnion soft
Change, block shower nozzle；And the utility model need to only use common fin, without good using radiating effect
Fin, reduces cost.
