Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of a kind of structure of clay shower nozzle of the present utility model.
The specific embodiment
As shown in Figure 1,3D clay printer of the present utility model comprises control system 21, clay shower nozzle 51, can allow clay shower nozzle 51 realize frame 31 and the feeding device 41 of three-dimensional motion.Control system 21 is controlled the running orbit of clay shower nozzle 51.Feeding device 41 is delivered to clay clay shower nozzle 51 and squeezes out filament state by clay shower nozzle 51, is then successively piled into the entity prototype identical with threedimensional model file.
In frame 31, be provided with the Control Shaft that at least three covers are connected with clay shower nozzle 51, can control clay shower nozzle 51 in the motion of tri-directions of XYZ.Every cover Control Shaft all comprises linear bearing 34, screw mandrel 33 and guide shaft 32, and linear bearing 34 is driven along guide shaft 32 and slided by screw mandrel 33, and screw mandrel 33 is driven by stepper motor 35, and stepper motor 35 is controlled by control system 21.Linear bearing 34 also can be driven by stepper motor 35 by various ways such as belt, Timing Belt, ball screws, and the utility model has only been enumerated wherein a kind of kind of drive.Control Shaft shown in figure is a kind of three axle parallel arm structures, every cover Control Shaft is all by a driven by motor, if it is motionless to control the motor of Y and Z direction, the Electric Machine Control of directions X moves upward, can realize clay shower nozzle 51 draws close to X-axis, the motor of directions X moves downward, can realize clay shower nozzle 51 to moving away from X-direction, other diaxons are also same principle, if the motor of tri-directions of XYZ is controlled upper and lower simultaneously, just realize the variation of Z direction, therefore, also just realized the motion of clay shower nozzle 51 in three dimensions.
It is the versions such as 201310282377.6 rectangular co-ordinate architecture, 200410069246.0 six shaft mechanical arm configurations, 201410063315 polar coordinates structure, 201310351560 serial structures that above-mentioned Control Shaft also can be used number of patent application, at this, does not just enumerate.
Clay shower nozzle 51 is arranged in frame 31 by frame for movement, and feeding device 41 can directly be connected with clay shower nozzle 51; Also can place separately, recycling conveyance conduit is connected with clay shower nozzle 51.The utility model can be realized long-time continuous feed by increasing the volume of feeding device 41 or a plurality of feeding devices 41 being set, to meet the demand of batch production or printing large scale ceramic product.Feeding device 41 can promote piston by external energies such as pressure-air, oil cylinder, electric cylinders, and the clay in feeding device 41 is squeezed to clay shower nozzle 51, finally by clay shower nozzle 51 ejection filament shape clays.
The stepper motor 35 that control system 21 of the present utility model is controlled tri-directions of XYZ by master control borad is realized the running orbit of controlling clay shower nozzle 51; By master control borad, control and extrude stepper motor 57 and control clay shower nozzle 51 ejection clay silks, turn-off time and spouting velocity.Extruding stepper motor 57 is connected with clay shower nozzle 51.3D clay printer of the present utility model also can arrange a plurality of clay shower nozzles 51, and respectively by a plurality of stepper motors with extrude stepper motor and control, can in same works, use respectively the material of unlike material different colours.
The structural representation of wherein a kind of structure of clay shower nozzle 51 of the present utility model as shown in Figure 2, clay shower nozzle 51 comprises screw sleeve 55 and is arranged on the feeding spiro rod 54 in screw sleeve 55, on described screw sleeve 55, be provided with charging aperture 56 and spray orifice 53, clay is entered in screw sleeve 55 by charging aperture 56 by feeding device 41, extrude stepper motor 57 and control the motion of feeding spiro rod 54, by control system 21, control and extrude opening of stepper motor 57, turn-off time and the speed of service, thereby control time and uninterrupted that clay sprays from spray orifice 53 by feeding spiro rod 54.Clay shower nozzle 51 also can have other versions, even directly uses the structures such as similar syringe needle, directly by pressure, is extruded also and is fine.
