The version of charging aperture directly affects the material feeding ability of charging effect and Plasticized component, and traditional injection moulding machine great majority are reinforced by the deadweight of material in hopper, conventional charging aperture is vertical centrosymmetric structure, simple in structure, but unfavorable to charging, easily at a material mouthful place, be split into bridge formation hole, adopt the charging aperture of unsymmetric structure because the contact angle of pusher in material and feeding cylinder is large, contact area is large, is conducive to improve charging efficiency, is also difficult for being split into bridge formation hole at a material mouthful place.
Further, described heater is positioned at the discharge port end of feeding cylinder, and heater comprises heating muff and the heating element heater that is positioned at heating muff.Heating element heater can be the device that electrothermal tube, electrical bar etc. can be used for heating.
Further, described heater is provided with temperature controller.For accurately controlling heating-up temperature, coordinate charging pusher speed simultaneously.
Further, at described extrusion nozzle place, be provided with a material traction bracing frame.When the plastics that melted are extruded from extrusion nozzle 8, traction and the support of by 11 pairs of bracing frames of silk material traction, extruding wire rod, make the consumptive material wire diameter of formation more stable, avoids extruding wire rod and walk downwards under the effect of deadweight.
Further, the end cross-sectional of described extrusion nozzle is rounded.
Further, described extrusion nozzle and feeding cylinder removably connect.The extrusion nozzle of replacing different size size for convenience detach.
The present invention also provides a kind of waste material recovery method of 3D printer, comprises the following steps: A. is by waste material heat fused; B. the waste material after fusing is discharged by extruding, form thread 3D and print raw material.
Further, adopt temperature controller to control heating-up temperature, according to heating-up temperature, adjust the velocity of discharge of waste material simultaneously, form thread 3D and print raw material.
Beneficial effect of the present invention:
One,, by the scrap melting that 3D printer is produced, then, by extruding, waste material is extruded by extrusion nozzle, directly form the thread raw material in alignment footpath, simple and quick realization is reclaimed and recycling, has also avoided waste and the pollution to environment, cost-saving.
Two, this device makes waste from stacking, extruding by the rotation propelling of feed worm, quick again continuously, has guaranteed the good quality of raw material after reclaiming.
Three, also can arrange by the size to extrusion nozzle, the size that the raw material that makes to reclaim mates the different thread raw materials of 3D printer, applicability is strong.
