Description
Technical field
The utility model relates to a kind of improvement of 3D printer extrusion device, refers in particular to a kind of 3D printer extrusion device that material subsides and metaboly is imagined that can avoid extruder ejection.
Background technology
The Makerbot Replicator 2X model desktop rank FDM type 3D printer that U.S. Makerbot company produces is first multiinjector 3D printer in world wide.This equipment can be used raw material types: PLA, ABS and dissolubility material.As shown in Figure 1, existing 3D printer extrusion device, comprises extruder 1; The bottom of described extruder 1 is provided with nozzle 4; The front side of described extruder 1 is provided with forefan 3; Between described forefan and the front side of extruder, be provided with fin 2.Its operation principle: raw material enters extruder position, there is heater block extruder 1 inside, will after heating raw materials, by nozzle 4, spray, and in layer stack is piled up, thereby reaches moulding object.Acting as of forefan and fin: the heater block to extruder inside dispels the heat, prevents that excess Temperature from causing extruder internals to damage.The 3D printer extrusion device of this structure, melting ejection after raw material enters and needs to be heated to 230 ℃ after extruder, in some small structure print procedure, because the raw material spraying can not get fully cooling, to there will be subsurface material completely not cooling, upper layer of material again stack is piled up, and causes occurring material collapse phenomenon, cannot mold required structure.
Utility model content
The utility model object is in order to overcome the deficiencies in the prior art, to provide a kind of material that can avoid extruder ejection to subside and the 3D printer extrusion device of metaboly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of 3D printer extrusion device, comprises extruder; The bottom of described extruder is provided with nozzle; The front side of described extruder is provided with forefan; Between described forefan and the front side of extruder, be provided with fin; The opposite side of described extruder is also provided with crosswind fan; The outlet of described crosswind fan is connected with airduct; The air outlet of described airduct is over against the raw material of extruding of the nozzle of extruder and nozzle below.
Preferably, described crosswind fan is vortex flow fan.
Preferably, on described extruder, be provided with fixed support; Described fixed support can be fixed crosswind fan support.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The 3D printer extrusion device of the utility model scheme, dries to nozzle and extruded material by setting up crosswind fan, can make to carry out from the high temperature extruded material of nozzle ejection cooling, and during work, every layer of melted material can be completely cooling, the generation of avoiding raw material to subside; The utility model can be used for printing small structure and highly higher part, has increased the range of application of the type 3D printer.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 2 is the stereogram of an angle of 3D printer extrusion device described in the utility model;
Accompanying drawing 3 is the stereogram of another angle of 3D printer extrusion device described in the utility model;
Wherein: 1, extruder; 2, fin; 3, forefan; 4, nozzle; 5, crosswind fan; 6, airduct; 7, fixed support; 8, air outlet.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 2-3 is 3D printer extrusion device described in the utility model, comprises extruder 1; The bottom of described extruder 1 is provided with nozzle 4; The front side of described extruder 1 is provided with forefan 3; Between described forefan 3 and the front side of extruder 1, be provided with fin 2, in order to strengthen the radiating effect of extruder; The opposite side of described extruder 1 is also provided with crosswind fan 5; Described crosswind fan 5 is vortex flow fan; Described crosswind fan 5 is connected with airduct 6; The air outlet 8 of described airduct 6 is over against the raw material of extruding of the nozzle 4 of extruder and nozzle 4 belows; On described extruder 1, be provided with fixed support 7; Described fixed support 7 is frame shape thing, and one end hook is on the right side of extruder 1, then across the top of extruder 1, then lives crosswind fan 5 along the left frame of extruder 1; Described fixed support 7 can be fanned crosswind 5 and fixes and support.
Operation principle of the present utility model:
Before work, first switch on power, after starting working, forefan 3 and crosswind fan 5 will be switched on simultaneously and be carried out work.When raw material is from nozzle 4 ejections, crosswind fan 5 will carry out a cooling effect to fused raw material, and while guaranteeing the work of 3D printer, every layer of melted material can be completely cooling, the generation of avoiding raw material to subside.
The 3D printer extrusion device of the utility model scheme, by setting up crosswind fan to nozzle and extruding raw material and dry, can make to extrude raw material from the high temperature of nozzle ejection and carry out coolingly, and during work, every layer of melted material can be completely cooling, the generation of avoiding raw material to subside; The utility model can be used for printing small structure and highly higher part, has increased the range of application of the type 3D printer.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
