6- linear bearings, 7- enlargers, 8- piezoelectric ceramic actuators, 9- pre-tighten micromatic setting, 10- elastic elements, the general plugs of 11-.
Specific implementation mode
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments to the utility model make into
One step is described in detail.
As shown in Fig. 1, a kind of micro- spray ejecting device of dropization piezoelectric type mechanical firing pin on demand, the ejecting device include spray
Mouth pipeline 1, is set to nozzle pipe bottom end, micro- spray chamber pedestal 2 with nozzle, and the other end of nozzle pipe is fixed on
On one fixed frame 3, the nozzle pipe is connected with feeding equipment 4, and striker 5, and blast tube are provided in the nozzle pipe
The linear bearing 6 of the direction of motion for guiding striker is provided in road；An enlarger 7 is provided in the fixed frame,
Piezoelectric ceramic actuator 8 is provided in enlarger, and one end of enlarger is connect with the top of the striker, enlarger
The other end connect with the preload micromatic setting 9 being set on fixed frame, the top of the striker is set with the linear bearing
It is equipped with reducible elastic element 10, which is set on the striker.
Preferably, in order to ensure leakproofness so that the smooth injection of droplet is provided with general plug in the nozzle pipe
11, which is located at the position being connect with the port of the linear bearing in nozzle pipe.
As preferred embodiment, the elastic element is reciprocal spring；The enlarger is that diamond shape micro-displacement is put
Great institutions；The end of the striker is circular end face.It is provided with inclined end face in micro- spray chamber pedestal, the inclined end face and institute
Closed end face can be formed by stating circular end face and matching.
In the utility model embodiment, the piezoelectric ceramic actuator is used for output displacement, the diamond shape micro-displacement amplification
Mechanism is used to amplify the output displacement of the piezoelectric ceramic actuator, so as to ensure the stroke of striker in effective range
It is interior.The preload micromatic setting is used to change micro- spray characteristic of printing equipment by the decrement of pressing spring by adjusting, and makes it
Meet application requirement；In addition, also the inclined end face in micro- spray chamber pedestal and striker end can be made by adjusting precompressed micromatic setting
Circular end face is closed to prevent micro- jetting liquid from leaking.
The ejecting device that the utility model embodiment provides, has many advantages, such as that micro- spray consistency is good, micro- spray frequency is high, from
And effectively improve the quality and efficiency of 3D printing.Illustrate the base for the ejecting device that lower the utility model embodiment provides briefly below
This operation principle：
（1）First, when carrying out 3D printing, the inclined end face in micro- spray chamber pedestal is closed with striker end circular end face,
Thus nozzle does not have fluid outflow；Under atmospheric pressure effect, printing " ink " is pushed into entire micro- spray chamber from feeding equipment
It is interior；
（2）Periodic electric signal is subject to piezoelectric ceramic actuator, piezoelectric ceramic actuator deforms upon and passes through water chestnut
The amplification of shape micro displacement magnifying mechanism makes entire mechanism to contract, and striker moves upwards under the elastic force effect of reciprocal spring,
The inclined end face of micro- spray chamber pedestal is detached with striker end circular end face at this time, and fluid enters in nozzle pipe；
（3）When disconnecting electric signal, piezoelectric ceramic actuator restores shape, and entire diamond shape micro displacement magnifying mechanism resiles
To drive striker to move downward to valve nozzles, the moment impact pressure of striker causes the liquid in nozzle pipe huge by one
Big momentum, this momentum make it that the viscous force of itself and surface tension be overcome to go out from the micro- spray of nozzle end.
Above-described embodiment is the preferable realization method of the utility model, is not the restriction to the utility model, not
Be detached from the utility model inventive concept under the premise of, it is any it is obvious replacement the scope of protection of the utility model it
It is interior.
