Technical field
The present invention relates to 3D printer technology field, in particular to a kind of nozzle structure of large-scale 3D printer.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
The large-scale 3D printer had now produces long term wear sealing ring when silk material enters, and causes air to enter in shower nozzle, makes the product quality produced bad.Bad owing to sealing in addition, the melting material in shower nozzle can be made to overflow shower nozzle from silk material inlet port, occur waste.
Summary of the invention
The object of the present invention is to provide a kind of nozzle structure of large-scale 3D printer, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A nozzle structure for large-scale 3D printer, comprises nozzle housing, it is characterized in that, described nozzle housing comprises charging housing, middle casing and nozzle body; Be provided with baffle plate in described charging housing, be provided with sealing device between the charging aperture in baffle plate and charging housing, sealing device comprises sealing ring, throw-out collar and spring; The periphery of described sealing ring is the conical surface, and is arranged on baffle plate; Described throw-out collar inner headed face is provided with the conical surface matched with the sealing ring conical surface, and its periphery matches with charging inner walls; Described spring is arranged between the inlet end face in throw-out collar and charging housing; Described charging housing offers steam vent, and steam vent is provided with exhaust apparatus, and exhaust apparatus comprises spheroid, and spheroid is provided with exhaust spring, and exhaust spring one end connects spheroid, and the other end is connected with clarifier, and clarifier is fixed on charging housing; Be provided with the first screen pack in described charging housing, and charging housing is provided with electric-heating-wire-heating circle; Be provided with the second screen pack in described middle casing, and middle casing is provided with infrared heater; Be provided with the 3rd screen pack in described nozzle body, and nozzle body is provided with hot water heat-conducting layer; The filter opening of described first screen pack, the second screen pack and the 3rd screen pack reduces successively.
The invention has the beneficial effects as follows, promote throw-out collar by spring, throw-out collar and sealing ring cone match, thus make sealing ring compress silk material, make sealing ring when Long-Time Service weares and teares, realize automatic compensation sealing, thus avoid air to enter in shower nozzle, cause product quality bad.Silk material enters after in charging housing, electric-heating-wire-heating circle produces high temperature makes rapidly silk material melt, the silk material do not melted completely cannot by the first screen pack, continue to melt in charging housing, melting material after thawing enters in middle casing, heated further by infrared heater, the silk material of thawing is made to be in molten condition, and enter in nozzle body by the second screen pack, by the hot water heat-conducting layer insulation on nozzle body, silk material is avoided to harden, jet hole is entered by the fused raw material after the 3rd filter screen filtration, jet hole is avoided to block, improve the quality of producing product.When the pressure of the pernicious gas produced when silk material melts is greater than the resistance of exhaust spring, promote spheroid, now pernicious gas enters clarifier from steam vent, after purification utensil pernicious gas, discharges clarifier, avoids contaminated environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the nozzle structure of a kind of large-scale 3D printer provided by the invention;
Fig. 2 is exhauster structure schematic diagram.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1-2 the is shown nozzle structure of a kind of large-scale 3D printer provided by the invention, comprising: charging housing 1, electric-heating-wire-heating circle 6, exhaust apparatus 2, infrared heater 10, sealing ring 3, throw-out collar 4, baffle plate, middle casing 9, nozzle body 13, hot water heat-conducting layer 14, first screen pack 11, second screen pack 12, gas 23, exhaust spring 22, clarifier 21, the 3rd screen pack 15 and spring 5.Be provided with baffle plate in described charging housing 1, be provided with sealing device between the charging aperture in baffle plate and charging housing 1, sealing device comprises sealing ring 3, throw-out collar 4 and spring 5; The periphery of described sealing ring 3 is the conical surface, and is arranged on baffle plate; Described throw-out collar 4 inner headed face is provided with the conical surface matched with sealing ring 3 conical surface, and its periphery matches with charging housing 1 inwall; Described spring 5 is arranged between the inlet end face in throw-out collar 4 and charging housing 1; Described charging housing 1 offers steam vent, and steam vent is provided with exhaust apparatus 2, and exhaust apparatus 2 comprises spheroid 23, spheroid 23 is provided with exhaust spring 22, exhaust spring 22 one end connects spheroid 23, and the other end is connected with clarifier 21, and clarifier 21 is fixed on charging housing 1; Be provided with the first screen pack 11 in described charging housing 1, and charging housing 1 is provided with electric-heating-wire-heating circle 6; Be provided with the second screen pack 12 in described middle casing 9, and middle casing 9 is provided with infrared heater 10; Be provided with the 3rd screen pack 15 in described nozzle body 13, and nozzle body 13 is provided with hot water heat-conducting layer 14; The filter opening of described first screen pack 11, second screen pack 13 and the 3rd screen pack 15 reduces successively.
