Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
As shown in Figs. 1-5, the utility model embodiment provides a kind of spray head for 3D printing construction material, including spray head
Ontology 1, the bottom of the head body 1 are equipped with spout 2, are equipped with material flowing lumen 3, the material stream in the head body 1
Cavity 3 is connected with the spout 2, is equipped at the position of the spout 2 described in capable of controlling in the material flowing lumen 3
The rotating mechanism 4 that spout 2 is opened and closed.
It is used for the spray head of 3D printing construction material described in the utility model embodiment, when spray head work, passes through control
The rotation speed and rotating cycle of the rotating mechanism 4, realization accurately controls discharging speed and load, when spray head does not work
When, it controls the rotating mechanism 4 and stops rotating, the rotating mechanism 4 can block material automatically to be continued to leak out, to make described
Spout 2 is closed, and feed is stopped, and is avoided since the generation of elephant occurs in windrow excessive flow caused by being not closed completely.
Furthermore, it is understood that the rotating mechanism 4 includes rotary shaft 401 and being circumferentially arranged along the rotary shaft 401
Multiple flabellums 402.
