The 3D printing ejecting device of above-mentioned technical problem is can solve the problem that, its technical scheme is included meltbility material by setting
Track motion be layering to be formed the extrusion mechanism to design a model, the charging mechanism for being fed meltbility material to extrusion mechanism and
By the quick-setting heating arrangements of meltbility material of extrusion, wherein
1st, the extrusion mechanism includes the feed tube by upper and lower fixing plate location and installation, is provided with the feed tube logical
The feeding spiro rod of bearing installation is crossed, what is installed stretched out on the upper nozzle connection upper mounted plate of feed tube in the upper end of the feeding spiro rod
Motor output shaft, the lower nozzle of feed tube are provided with dismountable shower nozzle.
2nd, the charging mechanism includes feed pipe, and the feed pipe connects the charging aperture on feed tube cylinder.
3rd, the heating arrangements are included in the fan heater set on bottom plate, and the blowing mouth of the fan heater is towards shower nozzle
Nozzle.
The shower nozzle has the specification of different extrusion diameters, can be required to choose to install the spray of different size according to different printings
Head.
For smooth discharging, the shower nozzle is made using iron Buddhist dragon barred body material, and iron Buddhist dragon material is to printed material (meltbility
Material) absorption affinity it is smaller so that printed material can smooth extrusion.
Conventionally, the rolling bearing is located at the upper nozzle of feed tube, and the set location generally corresponds to motor and feeding
The connecting portion of screw rod.
Conventionally, the charging aperture is located on the feed tube cylinder between upper and lower fixing plate.
To be heated evenly the meltbility material of extrusion, multiple fan heater circumference uniform distributions are set.
The beneficial effects of the utility model：
1st, can be right by the collective effect of charging mechanism and extrusion mechanism in the utility model 3D printing ejecting device structure
Meltbility material implements smoothly extrusion, after Teflon glue stick body material processing and fabricating shower nozzle, will not more cause
Blocking of the extruded material to shower nozzle, contribute to the cleaning work to shower nozzle after the completion of printing.
2nd, in the utility model structure, sprinkler design is dismantled and assembled mode, can be put according to the different occasions of printing and requirement
Change the shower nozzle of different size model.
3rd, the utility model is different from the traditional sprinkler heads of extruding and hot melting material on the market, it is not necessary to shower nozzle is heated, and
It is to be evenly arranged three fan heaters, and makes the thermal current of fan heater concentrate the printed material after alignment extrusion to consolidate its flash baking
Change, it is not in cave in stacking layer by layer to make it, further increases the quality of printing.
