The shaping jar is located and supplies the powder jar and return between the powder jar. Be provided with the several inclined plane in the crisscross funnel, the inclined plane distributes both sides and crisscross the setting, the bottom of crisscross funnel be equipped with with the through -hole of tube cell intercommunication returns. The utility model discloses the beneficial effect who has: adopt simple mechanical structure to filter the powder and retrieve and preserve in returning the powder steel bottle, it supplies the powder jar to recycle when needing to pack the powder in the steel bottle into, has simple structure, low in manufacturing cost, characteristics such as efficient.
Description
Technical field
The utility model relates to 3D printer technology field, is specifically related to the 3D gold of a kind of Hui Fen of having mechanismBelong to printer.
Background technology
3D printer claims again three-dimensional printer (3DP), is a kind of accumulation manufacturing technology, i.e. RP techniqueA kind of machine, it is a kind of mathematical model file is basis, uses special wax material, powdery metal or mouldsMaterial waits can jointing material, manufactures three-dimensional object by the jointing material of printing from level to level. Along with 3D beatsThe diversified development of printed material material and the innovation of printing technique, 3D prints not only and embodies in traditional manufacturingGo out outstanding development potentiality, simultaneously its glamour more extend to food manufacturing, clothes luxury goods, video display medium withAnd education etc. multiple with the people closely bound up field of living.
The Hui Fen mechanism of 3D metal printer adopts servomotor control to return moving up and down of powder cylinder more at present,The complete one deck powder of the every paving of scraper, reclaims cylinder decline certain altitude to reclaim powder. When need to be by the powder returning in powder cylinderWhile moving on to for powder cylinder, need to control scraper the powder reclaiming in cylinder is scraped to supplying powder cylinder. This mode efficiency is lower,And increase the extra cost of servomotor etc.
Utility model content
The purpose of this utility model is in order to make up the deficiencies in the prior art, and a kind of reasonable in design is provided,There is the 3D metal printer of Hui Fen mechanism.
In order to reach the purpose of this utility model, technical scheme is as follows:
A 3D metal printer with Hui Fen mechanism, has forming cavity, in described forming cavity, establishes successivelyBe equipped with moulding cylinder and for powder cylinder, it is characterized in that: be also provided with back powder cylinder, in described time powder cylinder, be provided with backPowder mechanism, described Hui Fen mechanism has staggered funnel, and described staggered funnel upside is provided with mesh screen, described friendshipWrong funnel bottom is connected with powder retrieving pipe, and described powder retrieving pipe bottom is connected with back powder steel cylinder.
Preferably: described moulding cylinder is supplying powder cylinder and returning between powder cylinder.
Preferably: the aperture of described mesh screen is 180 orders.
Preferably: in described staggered funnel, be provided with several inclined-planes, inclined-plane is distributed in both sides and is crisscross arranged,The bottom of described staggered funnel is provided with the through hole being communicated with described powder retrieving pipe.
The beneficial effect the utlity model has:
Adopt simple frame for movement by powder filter and be recycled to back in powder steel cylinder and preserve, while needs by steel cylinderIn powder pack into for powder cylinder recycling, the utilization rate of high metal dust, have simple in structure, manufactureThis low, efficiency high.
Brief description of the drawings
Fig. 1 is the structural representation that the utlity model has the 3D metal printer of Hui Fen mechanism;
Fig. 2 is the structural representation of staggered funnel in Fig. 1;
Fig. 3 is the cross section structure schematic diagram of Fig. 2;
Fig. 4 is the structural representation of mesh screen in Fig. 1.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is notOnly be confined to embodiment.
As Figure 1-Figure 4, a kind of 3D metal printer with Hui Fen mechanism, has forming cavity, instituteState and in forming cavity, be disposed with back powder cylinder 3, moulding cylinder 2 and for powder cylinder 1. Return in powder cylinder 3 and be provided with backPowder mechanism, described Hui Fen mechanism is provided with successively from top to bottom mesh screen 4, staggered funnel 5, powder retrieving pipe 6 and returnsPowder steel cylinder 7, mesh screen 4 is arranged on staggered funnel 5 upsides, and the aperture of mesh screen 4 is 180 orders. Scraper is from supplyingFirst the metal dust that powder cylinder 1 is scraped filters and removes larger particles and impurity etc. through mesh screen 4, after filtrationPowder enter in staggered funnel 5. Staggered funnel 5 bottoms have through hole, powder retrieving pipe 6 upper ends and described logicalHole is communicated with, and powder retrieving pipe 6 lower ends are communicated with time powder steel cylinder 7. Powder enters through powder retrieving pipe 6 from staggered funnel 5 againEnter back in powder steel cylinder 7 and store. In the time that the powder in time powder steel cylinder 7 amasss completely, can return powder steel cylinder 7 and return powderPipe 6 separates, and the powder returning in powder steel cylinder 7 is reloaded for re-using in powder cylinder 1, to improve metal powderThe utilization rate at end.
Staggered funnel 5 is secured by bolts in back on powder cylinder 3 inwalls. Staggered funnel 5 inside are provided with severalInclined-plane, inclined-plane is distributed in both sides and is crisscross arranged, and has two inclined-planes in the present embodiment, as shown in Figure 3,In sectional view, the first inclined-plane 51 and the second inclined-plane 52 are interspersed, and powder filters and enters friendship through mesh screen 4Mistakes and omissions bucket 5 is rear slides to the second inclined-plane 52 along the first inclined-plane 51, finally enters powder retrieving pipe 6 by base apertures.The inclined-plane being interspersed is conducive to reduce the airborne dust producing in Powder Recovery process, raises thereby reduce in working chamberDirt density, reduces the possibility of exploding.
Finally it should be noted that: only in order to the utility model to be described, also unrestricted practicality is new for above embodimentThe described technical scheme of type, therefore, although this description is new to this practicality with reference to each above-mentioned embodimentType has been described in detail, and still, those of ordinary skill in the art should be appreciated that still can be rightThe utility model is modified or is equal to replacement, and all do not depart from the skill of spirit and scope of the present utility modelArt scheme and improvement thereof, it all should be encompassed in claim scope of the present utility model.
