[background technology]
Melt extruding shaping (FDM) is a kind of widely used three-dimensionally shaped technology, its operation principle is after being melted by heating materials, to be extruded from printhead by material extrusion mechanism and rapidly cooled and solidified is shaping, this technology is confined to the forming materials of single color in early days in application, so the color category printing object is dull, color selecting is by the restriction of material color.Along with the development of technology, afterwards people develop utilize the work of three primary colors mixing principle melt extrude the colored 3D printhead of formula, by the distribution of red, green, blue three kinds of colors be in harmonious proportion out multiple color melted material and sent shaping.
In current searchable patent or document, three primary colors are distributed and produces the principle of multiple color or structure has more description, but there is no the colored 3D printer that three primary colors mixing color matching quality is higher in the market, one of this reason be wherein because in adopting three primary colors color theory to be applied to melt extrude formula 3D to print time, because the toughness of melting 3D printed material is higher, the higher secondary colors of effect can not be obtained as gouache color, so the object color printed mostly is random uncontrollable broken colour, and accurately can not control the object color that prints.
Application three primary colors color theory is for printing the strict object of outstanding control, abundant batch mixing must be carried out to after three primary colors material molten, three primary colors are matched colors full and uniform, and all really do not realize the device of this function in the printhead of present melting formula 3D printer, correlation technique is needed badly and is broken through.
[summary of the invention]
Object of the present invention is exactly solve existingly to melt extrude the impure problem of object color that formula colored 3D printhead prints goes out, a kind of device carrying out abundant batch mixing for melt extruding the colored 3D printhead of formula is proposed, the three primary colors material of melting can be made fully to be mixed, thus the material color that allotment place color is pure, and batch mixing process can not affect printing precision.
For achieving the above object, the present invention proposes a kind of blender melt extruding the colored 3D printhead of formula, comprise batch mixing support, be arranged on the heat block in batch mixing support, be inserted into the heating rod in heat block, be fixed on the elementary blending bunker bottom heat block, be arranged in the secondary blending bunker bottom elementary blending bunker and the insulation rod being inserted into secondary blending bunker inside, described batch mixing support is provided with symmetrical inclined plane, the inclined plane of symmetry is fixed with piezoelectric bimorph, the upper surface of described piezoelectric bimorph and the minimum range of elementary blending bunker are less than the monolateral Oscillation Amplitude of piezoelectric bimorph, described secondary blending bunker comprises vibration damping feed pipe, array batch mixing ring and discharging opening, described vibration damping feed pipe has two, upper end is communicated with the bottom of elementary blending bunker, and lower end is connected to the top of described array batch mixing ring, and the bottom of array batch mixing ring is connected with discharging opening.
As preferably, the top of described heat block is provided with guide cover, and described guide cover has three, is used for conducting Red Green Blue material silk respectively.
As preferably, one end of described piezoelectric bimorph is fixedly bonded in the upper end of described inclined plane by epoxy resin, the other end of described piezoelectric bimorph is free end, can carry out dither by high-frequency warpage to elementary blending bunker.
Feature of the present invention and advantage will be described in detail by reference to the accompanying drawings by embodiment.

Fig. 1 is the overall structure schematic diagram that the present invention melt extrudes the blender of the colored 3D printhead of formula;
Fig. 2 is the structural representation of secondary blending bunker in the present invention;
Fig. 3 is that the two-way of secondary blending bunker in the present invention liquidates batch mixing fundamental diagram.
In figure: 1-batch mixing support, 2-heat block, 3-heating rod, the elementary blending bunker of 4-, 5-guide cover, 6-piezoelectric bimorph, 7-level blending bunker, 8-are incubated rod, 9-three primary colors material silk, 71-vibration damping feed pipe, 72-array batch mixing ring, 73-discharging opening.
[detailed description of the invention]
Consult Fig. 1, Fig. 2 and Fig. 3, the present invention melt extrudes the blender of the colored 3D printhead of formula, comprise batch mixing support 1, be arranged on the heat block 2 in batch mixing support 1, be inserted into the heating rod 3 in heat block 2, be fixed on the elementary blending bunker 4 bottom heat block 2, be arranged in the secondary blending bunker 7 bottom elementary blending bunker 4 and the insulation rod 8 being inserted into secondary blending bunker 7 inside, described batch mixing support 1 is provided with symmetrical inclined plane 61, the inclined plane 61 of symmetry is fixed with piezoelectric bimorph 6, the upper surface of described piezoelectric bimorph 6 and the minimum range of elementary blending bunker 4 are less than the monolateral Oscillation Amplitude of piezoelectric bimorph 6, namely piezoelectric bimorph 6 with straightened condition during inoperative for boundary, towards the ultimate range of the direction warpage near elementary blending bunker 4, described secondary blending bunker 7 comprises vibration damping feed pipe 71, array batch mixing ring 72 and discharging opening 73, described vibration damping feed pipe 71 has two, upper end is communicated with the bottom of elementary blending bunker 4, and lower end is connected to the top of described array batch mixing ring 72, and the bottom of array batch mixing ring 72 is connected with discharging opening 73.
The top of described heat block 2 is provided with guide cover 5, and described guide cover 5 has three, is used for conducting Red Green Blue material silk 9 respectively.
Described heating rod 3 in described heat block 2 can select thermocouple heating rod, produces high temperature to heat heat block 2 to heating rod 3 after being energized.
