Embodiment
The invention will be further described with reference to the accompanying drawings and examples, but should not
It is interpreted as the above-mentioned subject area of the present invention and is only limitted to following embodiments.On the present invention is not departed from
In the case of stating technological thought, according to ordinary skill knowledge and customary means, make
Various replacements and change, it all should include within the scope of the present invention.
Referring to Fig. 1 to Fig. 6, the present embodiment provides a kind of section based on fixed point rotating shaft rotating-table apparatus
Energy type colour mixture 3D printing shower nozzle, including rotating disk 6 and shower nozzle 7.The shower nozzle 7 enters one for three
Go out colour mixture shower nozzle.The shower nozzle 7 include 1, three radiating tube 2 of copper nozzle, heating rod 3,
Deep bead 4, three trunnions 5 and thermistors；
The Surface coating of the copper nozzle 1 one layer of ceramic fibre, and ceramic fibre can ensure
The storage of heat, save the energy.The copper nozzle 1 is tapered, and the tip of its underpart is
Material mouth 101, its upper face are provided with three charging apertures 102, blind round hole I 103 and circle
Shape blind hole II 104.These three charging apertures 102 form feeding-passage between discharging opening 1 respectively,
I.e. feeding-passage has three, is finally all discharged by discharging opening 101.Wherein, three chargings
Mouth 102 is evenly distributed on the upper surface of copper nozzle 1, their mutual corresponding centers of circle
Angle is 120 °.The inwall of each charging aperture 102 is carved with one section of screw thread, and this section of screw thread is used to connect
Connect trunnion 5.The blind round hole I 103 is located on the axis of copper nozzle 1, the blind round hole
I 103 are used to install heating rod 3.
The heating rod 3 is arranged in blind round hole I 103.It should be noted that the circle
The discharging opening 101 of the distance from bottom copper nozzle of shape blind hole I 103 is 3mm.Conventional 3D printing
The length of the heating rod of machine is 20mm, and the length of heating rod 3 is 15mm in the present invention.So
Can try one's best it is buried enter blind round hole 103 in, and can reduce heat scatter and disappear, be also possible to prevent
Bad consumptive material scorification is collapsed in advance of radiating soft causes to promote powerless, shower nozzle to block.
The thermistor is arranged in blind round hole II 104.The heating rod 3 and temperature-sensitive electricity
Resistance passes through wire connecting power respectively.Three radiating tubes 2 pass through a trunnion 5 and one respectively
Individual charging aperture 102 connects.The lower end of the trunnion 5 is threadedly attached in charging aperture 102
Interior, upper end is embedded in the endoporus of radiating tube 2.The upper end of these three radiating tubes 2 connects respectively
Connect the passage of conveying different colours material.The deep bead 4 is fixed on the upper of copper nozzle 1
Side.The shower nozzle 7 of the present invention is by taking the top of buried heating rod 3, copper nozzle 1 to increase gear
The measures such as aerofoil 4, diminution copper mouth area of dissipation prevent heat to scatter and disappear and prevent heat diffusion from causing
Premature inflation plug.
The shower nozzle 7 is arranged on rotating disk 6.The rotating disk 6 is around fixed-axis rotation, and rotating disk 6
Upper to have several spherical necks, these spherical necks are distributed on same circumference.Referring to figure
10 (Figure 10 is an equivalent schematic of the operation principle of rotating disk 6 of the present invention), described turn
Disk 6 also includes a positioning ball, and the side of the positioning ball contacts with spring, opposite side
With the peripheral surface contacts where spherical neck.When rotating disk 6 rotates, spring promotes positioning
Steel ball fall into spherical neck rotating disk 6 is carried out it is spacing, be rotated further rotating disk 6 cause positioning steel
Post slips away spherical neck.Meanwhile the list of different dimensional accuracies is also equipped with the rotating disk 6
Shower nozzle, shower nozzle so of the invention realize the melting mixing of different colours, with closing single nozzle
Work.
Referring specifically to Fig. 8 and Fig. 9, the present invention is respectively used to prusa i3 3D printers and simultaneously
Joint arm 3D printer, their working method is identical, and printing is changed by rotary turnplate 6
Shower nozzle, 3D printer just can freely change printing head with spraying material in print procedure,
Printing for different parts requires to change the shower nozzle of different dimensional accuracies.The small shower nozzle of diameter
Slim filament is extruded for careful position, thick shower nozzle enters when being filled printing
Row efficiently filling.The printing precision of delicate area had so both been improved, has greatly reduced 3D again
The filling time is printed, so as to save the electric energy required for heating fusing material, and is reduced
The mechanical wear and the generation of material internal warm prestress that heat dissipation band is come.
In addition using sprays of the finite element analysis software Comsol Multiphysics to the present invention
Head carries out heat transfer loss analysis, and in annex, setting material is the simulation model：Fin-
Aluminum oxide, Tong Zui-copper, heating rod-cast iron, the normal pressure thermal capacitance of material, density, heat conduction system
Number is set in simulation document.The contact site temperature for setting heating rod and copper mouth is 200
Degree Celsius (heat point source), fan cooling power 2w.Its temperature profile, thermograde figure,
Energy storage density figure is as shown in Figure 11 to Figure 13.As can be seen that thermal source concentrate on heating rod with
Copper mouth contact part.Radiating tube temperature of lower is higher, thermograde is larger, radiating efficiency compared with
It is high.Can be by taking buried heating rod, increasing deep bead, diminution copper mouth on nozzle top
The measures such as area of dissipation prevent heat to scatter and disappear and prevent heat diffusion from causing 3D printing material to shift to an earlier date
Fusing causes to block shower nozzle.Such design, which serves, really reduces the lost effect of heat.
From this figure it can be seen that although copper mouth directly contacts with thermal source, the temperature of copper mouth can't
Burn it is especially high, on the one hand because Tong Zui outer surfaces radiate, on the other hand because fan and dissipate
Heat pipe guiding radiating, the purpose of radiating is to prevent 3D printing material in advance in radiating tube
Scorification blocks shower nozzle.
