Abstract
The utility model relates to an anti-blocking spraying head, and mainly solves the problem that a spraying head of a 3D (three-dimensional) printer adopting a conventional FDM (fused deposition modeling) technology is prone to blockage. The anti-blocking spraying head is characterized in that a nozzle adopts a double-hole nozzle, and a partition board is arranged between double holes; a switching valve is arranged between the nozzle and an electric valve and adopts a two-way switching valve, and the double holes of the nozzle correspond to a through hole of the switching valve respectively; and heating resistance wires are arranged on the side walls of the double holes of the nozzle. The two nozzle holes are controlled by the switching valve, and a material can only be discharged from one hole; and when one nozzle hole is blocked, the other can be switched to, so that the problem that the 3D printer cannot work when the spraying head is blocked is effectively solved.
Description
Technical field
The utility model relates to a kind of 3D printer head, is specifically related to a kind of anti-clogging shower nozzle.
Background technology
3D printing technique claims again rapid shaping technique (Rapid Prototyping Manufacturing, be called for short RP technology), according to the difference of its forming method, can be divided into stereolithography (Stcmolithography, SLA), laminated solid mass manufacture (Laminated Object Manufacturing, LOM), Fused Deposition Modeling (Fused Deposition Modeling, FDM), selective laser sintering (Selective Laser Sintering, SLS) etc.FDM rapid prototyping system and SLA, LOM, the maximum difference of the systems such as SLS is that FDM does not adopt laser system, therefore cost can be dropped to minimumly, is also the most a kind of 3D printing technique of extensive use at present.
FDM technique generally adopts low melting point filamentary material, and as PLA or ABS plastic silk, they are thermal source without the laser of high-energy-density, only need in shower nozzle, silk material can be heated to molten condition in electrically heated mode.When work, first determine each interlamellar spacing, path width, computer is cut into slices to three-dimensional computer model, generation pass, then in the mobile wire vent by path of computer control lower nozzle, spray silk is bonded on workbench in making aspect, layer-by-layer preparation so repeatedly, until last one deck, fuse Qi ties and forms desired physical model like this.Wherein shower nozzle is the most complicated part, material is heated fusing in shower nozzle, shower nozzle bottom has a nozzle to extrude with certain pressure for the material of melting, shower nozzle is along part section profile and fill extruded material when orbiting motion, with front one deck bonding curing rapidly in air, so repeatedly carry out obtaining entity component.
For the 3D printer of FDM technology, PLA or ABS plastic through high temperature melting, are shaped after ejection shower nozzle in shower nozzle after supercooling again.But in the situation that some are special, cause shower nozzle exit temperature lower, in this time, material may will solidify before also not spraying shower nozzle completely, so just likely can make shower nozzle stop up.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of anti-clogging shower nozzle, has mainly solved the susceptible to plugging problem of 3D printer head of existing FDM technology.
The technical scheme that the utility model adopts is: a kind of anti-clogging shower nozzle, comprise shell, and in described shell, be provided with successively from top to bottom transmission device, heater, motor-driven valve and nozzle, described nozzle is diplopore nozzle, between two holes, is provided with dividing plate; Between described nozzle and motor-driven valve, be provided with transfer valve, this transfer valve is bilateral transfer valve, and the diplopore of nozzle is corresponding respectively with the through hole of transfer valve; Described nozzle diplopore sidewall is provided with resistive heater.
Described nozzle is provided with extrusion device.
Described extrusion device is piezoelectric type device, and nozzle both sides are provided with two piezoelectricity terminals, and described nozzle is soft materials.
Transmission device is gear pump; Described heater is between gear pump and motor-driven valve, and heater is communicated with motor-driven valve with gear pump.
The beneficial effects of the utility model are: owing to taking technique scheme, these two jet holes are by transfer valve control, can only realize single hole discharging, when a jet hole is blocked while clogging, can be switched to another, effectively avoid being blocked while clogging when shower nozzle, the inoperable problem of 3D printer.
Accompanying drawing explanation

In figure 1, shell; 2, transmission device; 3, heater; 4, motor-driven valve; 5, nozzle; 6, transfer valve; 7, resistive heater; 8, extrusion device; 9, piezoelectricity terminal.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of anti-clogging shower nozzle, comprises shell 1, is provided with successively from top to bottom transmission device 2, heater 3, motor-driven valve 4 and nozzle 5 in described shell 1, and described nozzle 5 is diplopore nozzle, between two holes, is provided with dividing plate; Between described nozzle 5 and motor-driven valve 4, be provided with transfer valve 6, this transfer valve 6 is bilateral transfer valve, and the diplopore of nozzle 5 is corresponding respectively with the through hole of transfer valve 6; Described nozzle 5 diplopore sidewalls are provided with resistive heater 7.
Described nozzle 5 is provided with extrusion device 8.
Described extrusion device 8 is piezoelectric type device, and nozzle both sides are provided with two piezoelectricity terminals 9, and described nozzle is soft materials.
Transmission device 2 is gear pump; Described heater 3 is between gear pump and motor-driven valve 4, and heater 3 is communicated with motor-driven valve 4 with gear pump.
Shower nozzle exit arranges two mutually symmetrical nozzle bores 5, and these two nozzle bores 5 are controlled by transfer valve 6, can only realize single hole discharging, when a nozzle bore 5 is blocked while clogging, can be switched to another; Meanwhile, add resistive heater 7 in nozzle 5 inner sides, in the time that nozzle 5 is blocked, can opens resistive heater 7 and make it to melt and pass blocking.Effectively avoid being blocked while clogging when shower nozzle, the inoperable problem of 3D printer.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
