The utility model, in order to can be effectively fed forward by silk material, is arranged further to technique scheme: described wire feeder comprises motor gear transmission mechanism, mechanism's fixed head, silk material movable passageway, silk material flexible member hold-down mechanism,
Described motor gear transmission mechanism is fixed on described mechanism fixed head,
Described silk material movable passageway is arranged on the position tangent with described motor gear transmission mechanism output shaft, described output shaft is provided with fixed pulley, described silk material movable passageway is by passage left side plate and passage right side plate is separated by a distance forms, described passage left side plate and passage right side plate are fixed on described mechanism fixed head
Described silk material flexible member hold-down mechanism is by deformation element, adjusting bolt and nut composition, described flexible member is arranged on the trough rim of described silk material movable passageway, described flexible member one end and described passage right side plate are connected in one, the other end is unsettled, described nut is fixed on described passage right side plate, and described adjusting bolt withstands on described flexible member.
The utility model compared with prior art, has the following advantages:
1, devise the frame for movement of multiple nozzle integration, not only can complete multi-color printing, and compact conformation, volume is little, lightweight, thus effectively improves printing precision and speed.
2, adopt the wire feeder of far-end, multiple nozzle integration shower nozzle and wire feeder are separated, significantly reduce the weight of 3D printer port of printer, reduce the load in the 3D printer course of work, thus effectively improve print quality, speed and precision.
3, silk material compression degree is adjustable, ensure that a material is effectively fed forward.
