Description
Technical field
The present invention relates to 3D printing technique field, specifically a kind of smoke pre-heating 3D printer head.
Background technology
3D prints, and is, by software, 3D mathematical model is carried out layering sliding-model control, then uses powdery metal or plastics etc. can adhesive material, builds entity by the mode of successively piling up.3D printing technique, compared with traditional manufacturing technology, can save raw materials for production better.At now conventional on the market 3D printer, by thread heat-fusible materials heating and melting, squeezed by the shower nozzle of a fine channel and gush out, therefore need by need during passage keep heat energy do not scattered and disappeared, hot melt material condensation can cause the blocking of passage, and under hot soak condition, accurate nozzle easily produces thermal deformation, the accuracy of manufacture is caused to decline.
Summary of the invention
The present invention aims to provide a kind of smoke pre-heating 3D printer head, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of smoke pre-heating 3D printer head, is characterized in that: comprise conveying pipeline, the fixed disk be enclosed within conveying pipeline, the chassis be connected on fixed disk; Be provided with up-small and down-big shoulder hole in the middle of described chassis, aperture is connecting through hole, and macropore is installing hole, arranges clamping device in installing hole; Be provided with roundabout exhaust gases passes in described chassis, in exhaust gases passes, be provided with multiple heat exchanger plate; Be provided with in described fixed disk into smoke chamber and go out smoke chamber, enter flue gas locular wall has and be communicated to outside air intake duct, enter the inlet communication with exhaust gases passes in smoke chamber, go out smoke chamber and exhaust gases passes outlet and going out in smoke chamber to be provided with air exhauster; Described undersurface of bottom disc is also connected with shower nozzle, and shower nozzle is divided into the fixed mount be connected in installing hole, be arranged on nozzle on fixed mount and tube connector, and tube connector inserts connecting through hole and is communicated to conveying pipeline.
Further, described clamping device is multi-jaw chuck.
Beneficial effect of the present invention is:
One, shower nozzle is demountable structure, Fast Installation and dismounting can be realized by gripping mechanism, when the parts that precision prescribed is not high manufacture, can choose the larger spray-nozzle type sprinkler head in aperture is arranged on chassis, equally, when the parts that precision prescribed is higher manufacture, can choose the spray-nozzle type sprinkler head that aperture is less, structure is more flexible.
Two, be provided with roundabout exhaust gases passes in chassis, in exhaust gases passes, be provided with multiple heat exchanger plate; Be provided with in described fixed disk into smoke chamber and go out smoke chamber, enter flue gas locular wall has and be communicated to outside air intake duct, enter the inlet communication with exhaust gases passes in smoke chamber, go out smoke chamber and exhaust gases passes outlet and going out in smoke chamber to be provided with air exhauster; Can by the hot blast that produces in industrial processes or flue gas, be input in roundabout exhaust gases passes by air intake duct, and by the heat exchanger plate heat absorption in exhaust gases passes, the temperature on whole chassis is reached and produces height, can effectively avoid the hot melt raw material in shower nozzle to cool.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of smoke pre-heating 3D printer head provided by the invention.
Mark in figure: 1 being conveying pipeline, 2 being fixed disk, 3 being exhaust gases passes for going out smoke chamber, 4,5 be fixed mount, 6 be tube connector, 7 be nozzle, 8 be heat exchanger plate, 9 be chassis, 10 be air intake duct, 11 for entering smoke chamber, 12 for air exhauster.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of smoke pre-heating 3D printer head, is characterized in that: comprise conveying pipeline 1, the fixed disk 2 be enclosed within conveying pipeline 1, the chassis 9 be connected on fixed disk 2; Be provided with up-small and down-big shoulder hole in the middle of described chassis 9, aperture is connecting through hole, and macropore is installing hole, arranges clamping device in installing hole; Be provided with roundabout exhaust gases passes 4 in described chassis 9, in exhaust gases passes 4, be provided with multiple heat exchanger plate 8; Be provided with into smoke chamber 11 in described fixed disk 2 and go out smoke chamber 3, enter the air intake duct 10 smoke chamber 11 wall having and is communicated to outside, enter the inlet communication with exhaust gases passes 4 in smoke chamber 11, go out smoke chamber 3 and exhaust gases passes 4 outlet and going out in smoke chamber 3 to be provided with air exhauster 12; Bottom surface, described chassis 9 is also connected with shower nozzle, and shower nozzle is divided into the fixed mount 5 be connected in installing hole, be arranged on nozzle 7 on fixed mount 5 and tube connector 6, and tube connector 6 inserts connecting through hole and is communicated to conveying pipeline 1.Described clamping device is multi-jaw chuck.
In use, shower nozzle is demountable structure, Fast Installation and dismounting can be realized by gripping mechanism, when the parts that precision prescribed is not high manufacture, can choose aperture larger nozzle 7 shower nozzle is arranged on chassis 9, equally, when the parts that precision prescribed is higher manufacture, can choose aperture less nozzle 7 shower nozzle, structure is more flexible.Be provided with roundabout exhaust gases passes 4 in chassis 9, in exhaust gases passes 4, be provided with multiple heat exchanger plate 8; Be provided with into smoke chamber 11 in described fixed disk 2 and go out smoke chamber 3, enter the air intake duct 10 smoke chamber 11 wall having and is communicated to outside, enter the inlet communication with exhaust gases passes 4 in smoke chamber 11, go out smoke chamber 3 and exhaust gases passes 4 outlet and going out in smoke chamber 3 to be provided with air exhauster 12; Can by the hot blast that produces in industrial processes or flue gas, be input in roundabout exhaust gases passes 4 by air intake duct 10, and absorbed heat by the heat exchanger plate 8 in exhaust gases passes 4, the temperature on whole chassis 9 is reached and produces height, can effectively avoid the hot melt raw material in shower nozzle to cool.Adopt structure of the present invention simply, easily to realize, effectively improve the production efficiency of 3D printer.
