Description
Technical field
The utility model belongs to the utility model and belongs to the advanced manufacture field of 3D, particularly relates to a kind of surface processing device for 3D printing head.
Background technology
In recent years, 3d printer is more and more universal, but owing to being subject to the restriction of moulding process and shaping speed, the model that 3d printer prints is difficult to overcome the stacked texture formed in Z-direction, is subject to certain restriction like this for 3d printer in the extensive use of industry and commercial market.Conventional needle, to the process of 3d printer model, is all by upper ash, polishing, these steps of color spray, but due to 3d printer model general structure more complicated, so deal with consuming time, and high to the requirement of personnel, efficiency is low, has had a strong impact on the application that 3d is printed on commercial market.
Summary of the invention
The utility model object is to provide a kind of surface processing device for 3D printing head, comprise annular upper portion, annular lower portion, described annular upper portion is arranged with described annular lower portion is concentric, and wherein, the inside of described annular upper portion has two, left and right independently hollow semicircular cavity respectively;
The annular sidewall of annular upper portion is symmetrically distributed with left charging aperture and right charging aperture; The inside of the right and left of described annular lower portion is respectively arranged with independently concentric annular discharging opening.
The longitudinal section of described each annular discharging opening is inverted trapezoidal.
The left cavity of described hollow semicircular is glue storage chamber.
The right cavity of described hollow semicircular is omphalos material storage chamber.
The left discharging opening of described annular is glue discharging opening.
The right discharging opening of described annular is omphalos material discharging opening.
The beneficial effects of the utility model: the utility model this patent provides a kind of new 3D printing head mainly for 3D printer model surface treatment mode, make 3D printer model can overcome surperficial stacked texture, and processing is simple, practical.The utility model has owing to solving 3D printer model surface flatness and conventional machining process in the middle of practical application the objective problem necessarily distinguished.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the installation diagram of 3D printing head.
Wherein, shell 1, nozzle 2, heater element 3, holder 4, surface processing device 5, left charging aperture 5.2, annular upper portion 5.3, left cavity 5.4, left discharging opening 5.5, annular lower portion 5.6, right cavity 5.7, right charging aperture 5.8, right discharging opening 5.9.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further elaborated.
As illustrated in fig. 1 and 2, the utility model 3D printing head comprises shell 1, nozzle 2, heater element 3, holder 4, the surface processing device 5 be looped around on nozzle 1 outer wall.Described holder 4 hollow is provided with through hole and is fixedly installed in the cavity of shell 1, and described nozzle 2 one end is pass shell sharp-tongued, and the through hole of nozzle 2 other end docks with the through hole of holder 5 and forms consumptive material and carry cavity.Described model surface treating apparatus 5 covers on the sharp-tongued outer wall of described nozzle 2.Wherein heater element 3 is the annular-heating device that PTC pottery is made.
While mould prints, surface processing device 5 is also started working.
Surface processing device 5 comprises annular upper portion 5.3, annular lower portion 5.6, and described annular upper portion 5.3 is arranged with described annular lower portion 5.6 is concentric, and wherein, the inside of described annular upper portion 5.3 has two the independently left cavity of hollow semicircular 5.4 and right cavitys 5.7 respectively;
The annular sidewall of annular upper portion 5.3 is symmetrically distributed with left charging aperture 5.2 and right charging aperture 5.8; The inside of the right and left of described annular lower portion 5.6 is respectively arranged with independently concentric annular and goes out left material mouth 5.5 and right discharging opening 5.9.
The longitudinal section of each annular discharging opening is inverted trapezoidal.
The left cavity 5.4 of hollow semicircular is glue storage chamber.
The right cavity 5.7 of hollow semicircular is omphalos material storage chamber.
The left discharging opening 5.5 of annular is glue discharging opening.
The right discharging opening 5.9 of annular is omphalos material discharging opening.
First, white glue with vinyl passes in and out the left cavity of glue storage chamber 5.4 through the left discharging opening 5.5 of glue guide hole annular by left charging aperture 5.2, coat the slow curing glue such as white glue with vinyl at the 3d model surface printed and form glue layer, namely glue curing time controling was at 30 ~ 60 minutes, glue must have good adhesive force, makes glue fill and lead up sunk part in the middle of stacked texture as far as possible.
Then, omphalos material enters the right cavity in omphalos material storage chamber 5.7 through right discharging opening 5.9 by right charging aperture 5.8, smearing the 3d model surface of even glue, spray diameter and make omphalos at 50um ~ 200um sheet or powder, allow omphalos material attach and form omphalos layer on glue layer, during sprinkling, must be noted that the thickness of omphalos layer, keep the profile of model unaffected, this stage process requires that omphalos layer is as far as possible thin, as long as overlay model surface is just passable completely for energy.
Finally, after omphalos layer is handled well, in order to omphalos layer can be made no longer to come off, on omphalos layer surface, we need to carry out spraying formation protective layer with gloss oil, note on a small quantity repeatedly, prevent protective layer from affecting the effect of omphalos during spraying.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
