The specific embodiment
Below with reference to drawings and Examples, describe embodiments of the present invention in detail, to the present invention, how application technology means solve technical problem whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.Each feature in the embodiment of the present application and embodiment, the mutually combining under prerequisite of not conflicting mutually, all within protection scope of the present invention.
As shown in Figure 1, the 3D printing device of the embodiment of the present application includes the feed pipe 1 of feeding printing material, and the hollow space of feed pipe 1 is the transfer passage of printing material.This printing material can be printing consumables such as ABS or PLA filament, can be also that food is such as chocolate etc.; Or this printing material can be also Powdered or granular printing consumables, raw-food material etc.Feed pipe 1 includes bringing-up section 11, and the end of feed pipe 1 is shower nozzle 2, and the end of shower nozzle 2 is discharging opening 21.
The 3D printing device of the embodiment of the present application, also comprises feed component 4 and heating element heater 5.Feed component 4 is set to the printing material in feeding feed pipe 1, and heating element heater 5 is set to the printing material in bringing-up section 21 to be heated to soften.
Be heated to softening printing material, through feed pipe 1, be fed to shower nozzle 2, and extrude through the discharging opening 21 of shower nozzle 2.Or, print material in feed pipe 1 during feeding, the heating element heater that is arranged on feed pipe 1 periphery is heated to soften, and through the discharging opening 21 of shower nozzle 2, extrudes.The printing material ingress of air being extruded or other refrigerating gases, lower the temperature rapidly and harden and shape.
When softening printing material moves in feed pipe 1, be subject to the especially restriction of shower nozzle 2 hollow spaces and discharging opening 21 shapes of feed pipe 1.In general, the cross sectional shape of shower nozzle 2 hollow spaces is identical with the shape of discharging opening 21.Softening printing material when discharging opening 21 is extruded, form with and the shape of discharging opening 21 grades and big or small all identical thread or bars.That is to say, shower nozzle 2 and discharging opening 21, not only have the effect that softening material is transmitted and extruded, and also has the effect of softening material being carried out to the moulding and definite size (thickness in other words) in cross section.
In the application's embodiment, on shower nozzle 2, be provided with the syndeton for removably connecting, be convenient to change at needs cross sectional shape and/or when size of the printing material being extruded, corresponding parts can be connected on shower nozzle 2 by the mode removably connecting.
As shown in Figure 1, the 3D printing device of the embodiment of the present application also includes nozzle 3, and nozzle 3 includes through hole 31.Nozzle 3 removably connects on shower nozzle 2 by the syndeton on shower nozzle 2.Nozzle 3 removably connects with shower nozzle 2, be convenient to optionally change as required the nozzle 31 with different through holes 31 to print, or optionally nozzle 3 is connected on shower nozzle 2 and is printed as required, or optionally nozzle 3 is unloaded and printed from shower nozzle 2 as required.That is to say, the application's embodiment, can directly print by shower nozzle 2 and not need nozzle 3 to be connected on shower nozzle 2, also can select the nozzle 3 with different through holes 31 to be connected on shower nozzle 2 and to print.
In the application's embodiment, the shape of discharging opening 21 comprises circle, ellipse, triangle, rectangle or polygon.The cross sectional shape of the through hole 31 of nozzle 3 can be circle, ellipse, triangle, rectangle or polygon.The cross sectional shape of the through hole 31 of nozzle 3 and the shape of discharging opening 21, can be identical, also can be not identical.
When the cross sectional shape of through hole 31 of nozzle 3 is identical with the shape of discharging opening 21, from shower nozzle 2 and discharging opening 21 through and the shape of cross section of the printing material extruded from nozzle 3, can't change.Such as, when the cross sectional shape of the through hole 31 that is shaped as circle and nozzle 3 of discharging opening 21 is also circular, the cross section of the printing material of extruding from nozzle 3 is still for circular.When the cross sectional shape of through hole 31 of nozzle 3 is not identical with the shape of discharging opening 21, from shower nozzle 2 through and the shape of cross section of the printing material extruded from nozzle 3, will change.Such as, the cross sectional shape of the through hole 31 that is shaped as circle and nozzle 3 of discharging opening 21 is also for triangle or rectangle etc. are when non-circular, the shape of cross section of the printing material of extruding from nozzle 3 will change, and becomes identical with the cross sectional shape of the through hole 31 of nozzle 3.Thereby the 3D printing device of the embodiment of the present application, can regulate the shape of cross section of the printing material being extruded.
The cross-sectional sizes (size of cross section) of the through hole 31 of nozzle 3 and the size (size of discharging opening) of discharging opening 21, can be identical, also can be not identical.And the cross-sectional sizes of the through hole 31 of nozzle 3 and the size of discharging opening 21, can have influence on print material at nozzle 3 and shower nozzle 2(or feed pipe 1) in translational speed.Such as, when the section ratio discharging opening 21 of the through hole 31 of nozzle 3 large, print the translational speed of material in nozzle 3, will be slower than the translational speed in feed pipe 2.The section ratio discharging opening 21 of the through hole 31 of nozzle 3 hour, print the translational speed of material in nozzle 3, will be faster than the translational speed in feed pipe 2.Thereby the 3D printing device of the embodiment of the present application, can regulate cross section size and the extruded velocity of the printing material being extruded.
In the application's embodiment, nozzle 3 can be threaded connection on shower nozzle 2, and shower nozzle 2 is from discharging opening 21 one end, and outer surface is provided with screw thread, and nozzle 3 connects on the inwall of one end of shower nozzle 2 internal thread is set.When needs are connected on shower nozzle 2 by nozzle 3, nozzle 3 can be enclosed within to the periphery of shower nozzle 2 from the discharging opening 21 of shower nozzle 2, nozzle 3 and shower nozzle 2 are together by a threaded connection.Thereby, can make the printing material softening through shower nozzle 2 and discharging opening 21, enter into nozzle 3, and extrude through the end of nozzle 3.
In other embodiment of the application, nozzle 3 also can removably be connected on shower nozzle 2 by the mode of clamping.In 3D printing device, extrude the part of softening material, volume is generally all less, thereby weight is lighter, and softening printing material is in moving process, the dynamics that imposes on passage is general also less, when therefore nozzle 3 is connected on shower nozzle 2 by the mode of clamping, only need less chucking power can keep being connected of nozzle 3 and shower nozzle 2, and not can because of gravity or print material and pressure come off.Certainly, when nozzle 3 snaps fit onto on shower nozzle 2, by fixed part, nozzle 3 being fixed on shower nozzle 2, to strengthen the annexation of nozzle 3 and shower nozzle 2, is also feasible certainly.
On the outer surface of shower nozzle 2, be provided with perpendicular to shower nozzle 2 axis directions the clamping position for removably connecting, nozzle 3 connects on the inwall of one end of shower nozzle 2 and is provided with the buckling groove removably connecting perpendicular to shower nozzle 2 axis directions and with this clamping position.When needs are connected on shower nozzle 2 by nozzle 3, nozzle 3 can be enclosed within shower nozzle 2 from the side of shower nozzle 2, utilize coordinating of the buckling groove of nozzle 3 and clamping position on shower nozzle 2, nozzle 3 and shower nozzle 2 are linked together.Thereby, can make the printing material softening through shower nozzle 2 and discharging opening 21, enter into nozzle 3, and extrude through the end of nozzle 3.
