Description
Technical field
The utility model is related to a kind of 3D printer equipment.
Background technology
3D printer is also known as three-dimensional printer, is a kind of machine of a kind of accumulation manufacturing technology, i.e. RP technique, it
Based on being a kind of mathematical model file, with special wax material, powdery metal or plastics etc. can jointing material, pass through printing one
Jointing material layer by layer come manufacture three-dimensional object.Current 3D printing technique is divided into following several printed materials or printing type：
1. some 3D printers use the mode of " ink-jet ".Printer port of printer is used by one layer of very thin liquid plastic
Substance spray is on mold pallet, and this coating is then placed in being handled under ultraviolet.Mold pallet declines minimum afterwards
Distance, so that next layer of stacking is come up.
2. being called the technology of " fused deposition modeling " using one kind, whole flow process is that plastics are melted in printhead, is then passed through
The mode of depositing plastic material fiber just forms thin layer.
3. being called the technology of " laser sintered " using one kind, print media is used as using powder particle.Powder particle is sprayed
One layer of very thin powder bed is formed on mold pallet, then founding is consolidated into designated shape by the fluid binder sprayed
Change.
4. using the electron stream fusing powder particle in vacuum, labyrinth as hole and cantilever is included when running into
When, it is accomplished by adding gel or other materials in medium to provide support or for taking up space.This amount of powder will not be by
Founding, last only need to fall to support thing with water or gas washout just can form hole.
At present, using plastics can jointing material as the printer of printed material, the printhead of existing 3D printer can only use
Wire rod, wire rod uses plastic raw materials, is produced by process equipment.Using the 3D printer of wire material typically using monochromatic printing,
Such as think that multi-color printing need to constantly change wire rod, this is pretty troublesome.The print speed of 3D printer is slower simultaneously, if accelerated
Print speed, easily causes printhead overheat, and product deformation is even resulted in and caved in.
Utility model content
For 3D printer leaf printhead in the prior art plastic wire and print speed can only be used excessively slowly etc. not enough,
The technical problems to be solved in the utility model is to provide a kind of usable particulate material, the 3D printer of raising print speed and set
It is standby.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of 3D printer equipment of the utility model, sets screw feed mechanism, including drive in the printhead of printer
Dynamic device, the screw rod and barrel being connected with drive device output shaft, wherein, in screw rod inside barrel, drive device peace
Loaded on one end outside barrel, the feed end of screw rod is connected with the discharging opening of a hopper, screw rod discharge end connection print-head nozzle, spiral shell
Cylinder is outside to be laid with Electrothermal ring.
Cooling device, including blower fan and airduct are additionally provided with the spray Zi, one of the lunar mansions of printhead, airduct is connected with the air outlet of blower fan,
The spray Zi, one of the lunar mansions outlet port of the air outlet correspondence printhead of airduct, and it is servo-actuated with printhead.
Blower fan is installed in 3D printer equipment, and the air outlet of airduct is fixedly connected with printhead.
Airduct is closing hose connector.
The online non-premix color matching feeding system of liquid color masterbatch is connected between the discharging opening of hopper and the feed end of screw rod.
The utility model has the advantages that and advantage：
1. the utility model changes the mode of operation of current plastics macromolecule 3D printer, without using well prepared in advance
Wire plastics high polymer material, only need to directly add graininess or powdered thermoplastic macromolecule material, and addition
Can be while mixture colouring agent during material, it is possible to achieve colored 3D printing functions.
2. the utility model 3D printer discharging opening is furnished with cold air refrigerating device, print speed can be improved, and provide modeling
Expect that material heats volatilized gas concentration unit, so as to realize the use in the closed small space of family so that the family of 3D printer
Front yard popularization, which is used, to be possibly realized.
It is online non-premixed that 3. the utility model is connected to liquid color masterbatch between the discharging opening of hopper and the feed end of screw rod
Color feeding system, can be achieved online color matching, the aesthetic appearance of lifting printing product.
Brief description of the drawings
Fig. 1 is the print head structure of 3D printer in the prior art；
Fig. 2 is the utility model 3D printer printhead internal structure schematic diagram；
Fig. 3 is the structural representation that the utility model sets air duct on the outside of 3D printer printhead.
Wherein, 1 is nozzle, and 2 be screw rod, and 3 be barrel, and 4 be heating collar, and 5 be drive device, and 6 be hopper, and 7 be blower fan, 8
It is air outlet for airduct, 9,10 be 3D printing wire rod, and 11 be driven roll, and 12 be drive roll, and 13 be guide sleeve, and 14 be shower nozzle.
Embodiment
The utility model is further elaborated with reference to Figure of description.
A kind of structure of 3D printer of the utility model in the printhead of printer as shown in Fig. 2 set screw feed
Mechanism, including drive device 5, the screw rod 2 and barrel 3 that are connected with the output shaft of drive device 5, wherein, it is located at barrel in screw rod 2
Inside 3, drive device 5 is installed on the outside one end of barrel 3, and the feed end of screw rod 2 is connected with the discharging opening of a hopper 6, and screw rod 2 goes out
Expect to be laid with Electrothermal ring 4 outside end connection print-head nozzle 1, barrel 2.
The utility model by the way of screw propulsion by printing feedstock transportation to print-head nozzle 1, such knot
Structure, which is set, does not limit the wire-form of printing raw material, but graininess or powdered applicable.So set in the 3D printing
Standby above directly directly to be printed using particle or powdered thermal plastic high polymer plastics, commercially available without buying uses shaping
The wire rod that process equipment and mould are produced in advance.
The utility model is additionally provided with cooling device, including blower fan 7 and airduct 8, airduct 8 and wind at the spray Zi, one of the lunar mansions 1 of printhead
