Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As shown in Figure 1 to Figure 3, the nozzle component of the 3D printer that first embodiment of the present utility model is proposed, including from
Under the supreme nozzle 1 being sequentially connected, heating copper billet 2, wire feed trunnion 3, fixed block 5, wire feed trunnion it is peripheral fixed circle
Radiator 4, lower end and heating 2 threaded engagement of copper billet of nozzle 1, the upper end of nozzle 1 is provided with external screw thread, heats copper billet 2
Lower end be provided with the internal thread hole being engaged with the external screw thread of nozzle 1, heat under the upper end of copper billet 2 and wire feed trunnion 3
End threaded engagement, the lower end of wire feed trunnion 3 are provided with external screw thread, and the upper end for heating copper billet 2 is provided with and 3 lower end of wire feed trunnion
The internal thread hole that external screw thread coordinates.The radiator 4 of circle, and the outer wall and radiator of wire feed trunnion 3 are cased with outside wire feed trunnion 3
4 threaded connections.So the heat of wire feed trunnion 3 is disperseed by radiator 4, so as to prevent heat transfer to fixed block 5 and motor
10, affect printing effect.Also the bad caused plug of trunnion radiating is solved the problems, such as simultaneously.Extend printer service life.
The fixed heater 13 heated by which in heating copper billet 2, meanwhile, thermometric is additionally provided with heating copper billet 2
Resistance 12, is electrically connected with them by one piece mini of panel 7, realizes temperature control.Panel is provided with electric wire and connects
Mouth 11, and panel 7 is fixed on the surface of motor, changes electronic devices and components without the need for dismounting more multi-part, realizes Fast-Maintenance.
Lose to reduce the heat on heating copper billet 2, can be with one layer of resistant to elevated temperatures heat-preservation cotton of parcel, the insulation on heat block 2
