The structure of fan housing 30 is described in detail with reference to Fig. 5 and Fig. 6, on the whole, shape in the ontology of fan housing 30
It is located at the first wall surface 33 where model cooling fan 31 at having cooling air channel and heat dissipation wind channel, cooling air channel air inlet 36（Top
Face）, and cooling air channel air inlet 36 is the identical semicircle of two sectional areas, 36 sectional area of cooling air channel air inlet is more than cooling
37 sectional area of duct outlet and cooling air channel extend towards obliquely downward, ensure that left and right sides wind pressure is identical, passing through cooling air channel will
Cooling wind is guided at left and right sides of 30 body interior of fan housing from print platform 4, make extruding part consumptive material obtain it is comprehensive
Uniform cooling.The air inlet of heat dissipation wind channel is located at the second wall surface 34 where 18 fan of cooling fin, needs to stress,
Heat dissipation wind channel includes：One main air duct and a pair of of auxiliary air duct positioned at main air duct both sides, 38 sectional area of main air duct air inlet are big
In main air duct air outlet sectional area, most of radiation air is guided to 18 surface of cooling fin, with ensure feeding chamber and melt chamber it
Between temperature gradient, avoid feeding chamber medium temperature spend height cause consumptive material melt in advance block feedhole 23.In the inner wall of main air duct
On open up there are two side open a window 39, side windowing 39 extend to 19 top edge of heat block between two cooling air channels and formed two
Elongated auxiliary air duct assists the wind pressure in air duct to be provided by 18 fan of cooling fin, and wind pressure is told somebody what one's real intentions are, and air quantity is also smaller, but can be
It is effectively formed low-pressure air current between heat block 19 and plastic wind cover 30, plastic wind cover 30 is avoided to be toasted for a long time by 19 high temperature of heat block
And aging deforms.
Since long term high temperature heats melt in trunnion 17 and nozzle 20, will necessarily residual impurity, wherein including mainly organic
The gummy residue being precipitated after the carbide and consumptive material high temperature of object dust high-temperature residual, organic dust carbide can pass through consumptive material
Wipe clean material mechanism is effectively prevented from, but consumptive material itself is precipitated when the gummy residue in impurity is high temperature, mostly can be residual
It stays in the inner wall of feedhole 23 and nozzle 20.Nozzle 20 belongs to vulnerable part, needs to regularly replace, and the service life of trunnion 17
Longer, wherein accumulating over a long period for gummy residue can bring strong influence to printing effect.In order to effectively solve at low cost
The above problem, our built-in one section of high temperature resistant four fluorine tube 40 in the feedhole 23 of trunnion 17, when needing replacing or clearing up, nozzle
20, the entirety that heat block 19 and trunnion 17 form is unloaded from extruder 16, you can quickly and easily will be resistance to from 17 tail portion of trunnion
High temperature four fluorine tube 40, which takes out, to be replaced, and after the taking-up of high temperature resistant four fluorine tube 40, is directly filled in from 17 tail end of trunnion with cotton swab i.e. erasable
Feedhole 23 is wiped, maintenance and cleaning is very convenient.
In order to enable those skilled in the art to be more clearly understood and implement the present invention, the 3D of the present invention is beaten below

The printable file being sliced on computer is inserted by SD card in SD card slot 8, being chosen in touch display screen will print
File, after click starts, heated nozzle 20 is arrived print temperature by heat block 19, and raw material threadiness consumptive material to be printed is placed in machine
On the material axis 12 on the side of frame 2, feeding motor 15 is sent into from passage 21, feeding motor 15 is by squeezing out gear by consumptive material from extruder
16 promote trunnions 17, consumptive material to melt under the action of heat block 19 to viscous state, click and feed button, machine automatic feed and from
Nozzle 20 squeezes out.Nozzle is driven by X-axis motor 10 and returns coordinate origin, and print platform 4 passes through Z axis motor 14 and y-axis motor
12 drives rise to coordinate origin, and printer starts to read mimeograph documents, the collaboration that nozzle and print platform 4 pass through three spindle motors
According to the instruction campaign in mimeograph documents, model is accumulated out in platform topsides layer heap.Model printing finishes, and print platform 4 drops to
Minimum point, nozzle 20 return XY axial coordinate origins, and at the appointed time rear automatic shutdown.In print procedure, double wind are continued through
Fan Five-channel radiating subassembly is effectively cooled down or is radiated to molded model, cooling fin 18 and fan housing 30, is preferably protected
Demonstrate,prove product quality and and its service life.
