Description
Technical field
The present invention relates to a kind of FDM fusion sediments formula 3D printer field, the silk extrusion device of particularly a kind of shower nozzle.
Background technology
3D printer thought originated from for 19 end of the centurys, and was able to develop and promotes in the eighties in 20th century, and its scientific name is " fast
Rapid-result type ".The principle of FDM fusion sediment formula 3D printers is that thermoplasticity filamentary material delivers to hot melt spray by silk extrusion device
Head, and heat in the showerhead and be melted into semi liquid state, then it is extruded out, selectively apply on the table, quickly
One layer of certain thickness sheet profiles are formed after cooling, layer cross section shaping completes aftertable and declines certain altitude, then carries out
Next layer of deposition, so circulation, ultimately form three-dimensional objects part.
The feeding speed and pressure of the silk extrusion device of 3D printer shower nozzle, directly affects the three-dimensional product of 3D printing processing
The quality of product, precision and surface effect, are the core important components of 3D printer.
Current existing silk extrusion device or mechanism there are problems that following：
1st, easily there are the phenomenons such as abrasion in the course of the work in feed device, the silk abnormal, wire feed of conveying can be caused unstable etc.
Problem；
2nd, the charging aperture and discharging opening of existing feed device, some are too small, and some are excessive, if too small material silk is present
Deviation or the easy generation catching phenomenon of deformation, excessive meeting produce influence to pushing precision.
So needing a kind of new technical scheme of offer to solve the above problems..
The content of the invention
In order to overcome the shortcomings of background technology, the present invention provides a kind of silk extrusion of simple and reliable 3D printer shower nozzle
Device.
The technical solution adopted in the present invention：A kind of silk extrusion device for 3D printer shower nozzle, including drive dress
Put and elastic force pedestal；Described drive device includes motor and gear, and geared sleeve is on the output shaft of motor；Described elastic force
Pedestal includes base, handle, directive wheel and the spring between base and handle, and the two ends of spring are born against the bottom of at
On seat 21 and handle；Described motor output shaft passes through base, and base is fixed on motor；First is provided with described base
Rotating shaft, taper knob is in first rotating shaft；The second rotating shaft is provided with described handle 22, directive wheel is sheathed on the second rotating shaft
On.
Described base and handle is respectively provided with fluted, and the groove of the two ends of spring respectively with base and handle offsets.
Described first rotating shaft is made up of screw and axle sleeve, and axle sleeve is sheathed on screw, and is fixed on base through handle.
The second described rotating shaft is made up of screw and axle sleeve, and axle sleeve is sheathed on screw, and is fixed on handle through directive wheel
On.
Described directive wheel is V-structure directive wheel, and its v-angle angle is 90 ~ 120 degree.
Described handle is provided with charging aperture；Described base is provided with discharging opening；Described charging aperture top is provided with one
Chamfering.
Described charging aperture and the bore dia of discharging opening are 2mm；Chamfering on described charging aperture is C3.
The beneficial effects of the invention are as follows：Compared with prior art, silk extrusion dress of the present invention for 3D printer shower nozzle
Put during practice, under the force of a spring, V-type directive wheel is moved to wire feeding gear direction, work as wire feeding gear
When having silk and directive wheel between, directive wheel extrudes silk king's wire feeding gear direction, so that gear mesh silk produces foot
Enough grasps, it is reliable；Diameter to charging aperture carries out conceptual design, has both met pushing precision requirement, is avoided that again
Silk clamping stagnation problem, simultaneously because devising chamfering on charging aperture so that handling silk is more easy.
