Description
[technical field]
The utility model relates to a kind of 3D printing head, and particularly a kind of structural improvement of 3D printing head, belongs to 3D and beatPrint technical field.
[background technology]
Along with scientific and technical development, fusion sediment moulding 3D printer has become current focus industry. It is one notRely on laser as the moulding energy and by various silk material (as engineering plastics ABS, polycarbonate etc.) heating and melting and then heapThe method of long-pending moulding. Heating shower nozzle, under the control of computer, according to the cross section profile information of product parts, does X-Y plane fortuneThe motion of moving and Z direction, thermoplastic filaments material is delivered to nozzle by wire feeder, and is heated to molten condition in nozzle, thenBe extruded out, be coated in selectively on workbench, fast cooling rear formation one deck cross section profile. Complete after a layer cross sectionNozzle increases the height of one deck, then carries out lower one deck coating, repeats above-mentioned action, until form three-dimensional objects. And current 3DMechanism's complexity of the shower nozzle of printer, and the Position Design that cooling fan is wherein installed is improper, and can not be very after shower nozzle material extrusion outGood cooling, can result in blockage, and then cause the surface quality of printout poor.
[summary of the invention]
For above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of simple in structure, good heat dissipation effect3D printing head.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of 3D printing head, comprise fixed head, nozzle, Teflon pipe, the trunnion that is communicated with nozzle material-feeding end, radiator andFan, described nozzle is connected with heater, it is characterized in that, and described radiator muff-joint is at the outer surface of trunnion, described fan positionIn the outside of radiator correspondence position.
Preferably, the height of described fan and radiator is basic identical.
Further, the outside of described fan is provided with the fan guard of air-flow guide radiator.
Further, the bottom of described fan guard is provided with air outlet near nozzle place, so that part air-flow guiding printout.
Further, described radiator is the aluminium radiator that comprises multiple interlayers.
Preferably, described Teflon pipe is through to nozzle material-feeding port from trunnion inside.
Preferably, the feed mechanism of described 3D printing head adopts long-range separate design.
Further, described heater comprises heating head, heating tube and thermistor.
Beneficial effect:
The utility model, owing to having adopted technique scheme, has following beneficial effect:
Fan is relative with the position of radiator, and cold wind can directly blow to radiator, to carry out cooling to it; Owing to having increased windFan cover, can lead to air-flow, and one side is carried out cooling to radiator, carries out cooling on the other hand to the object of printing;Teflon pipe is through to nozzle material-feeding port, can ensure that material extrusion is even; The feed mechanism of shower nozzle adopts long-range separate design, makesFeed mechanism separates with shower nozzle, can alleviate shower nozzle weight, increases the stability of shower nozzle.

[detailed description of the invention]
Below in conjunction with specific embodiment, the utility model is described in further detail, but model that the utility model comprisesEnclose and be not limited to this.
Embodiment 1
As Figure 1-4, the present embodiment is a kind of 3D printing head, comprises fixed head 1, nozzle 2, Teflon pipe 3, connectsTrunnion 4, the aluminium radiator 5 that contains multiple interlayers and the fan 6 of logical nozzle 2 feed ends, described nozzle 2 connects heater7, described heater 7 comprises heating head 71, heating tube 72 and thermistor 73, and Teflon pipe 3 runs through from trunnion 4 insideTo the charging port of nozzle 2, even to ensure material extrusion, radiator 5 is enclosed within the outer surface of trunnion 4, and fan 6 is positioned at radiator5 outside correspondence position, the two is highly basic identical, is beneficial to fan 6 and carries out cooling to radiator 5. Heater 7 HesRadiator 5 is screwed and is arranged on fixed head 1, and the outside of described fan 6 is provided with fan guard 8, described fan guard 8Be screwed on fixed head 1, bottom, guides air-flow by air outlet 9 near nozzle 2 places, the moving of cold airflowMoving direction as shown by the arrows in Figure 4, carries out fan 6 cooling on the one hand to radiator 5, carry out cold on the other hand to printoutBut.
The utility model is simple and reasonable, has simplified the part of 3D printing head, and shower nozzle volume is little, lightweight, and coolingEffective, can effectively prevent putty. In addition, in the present embodiment, the feed mechanism of described 3D printing head adopts long-range separation to establishMeter, makes feed mechanism separate with shower nozzle, can further alleviate shower nozzle weight, increases the stability of shower nozzle.
The above be only preferably specific embodiment of the present utility model, but protection domain of the present utility model is not limited toThis, any be familiar with those skilled in the art the utility model disclose technical scope in, according to skill of the present utility modelArt scheme and design thereof are equal to replaces or changes, and all should be encompassed in protection domain of the present utility model.
