Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Shown in Fig. 4, the utility model provides a kind of 3D printer head extrusion mechanism, comprise the material guiding pipe 3 extruded assembly 1, nozzle component 2 and connect the two, described assembly 1 of extruding comprises the pedestal 102 of band baffle plate 104, is axially vertical at baffle plate 104 with the active roll 106 of side and driven roll wheel 108, clamping mechanism, described active roll 106 is slidably connected with pedestal 102, and driven roll wheel 108 is inconsistent by clamping mechanism and active roll 106; The intersection of described baffle plate 104 and two rollers wheel 106,108 is provided with lug boss 110; Described nozzle component 2 comprises shower nozzle 202, heating member 204, scatterer 206 and interior pipe 208, and heating member 204 one end is connected with scatterer 206 by interior pipe 208, and heating member 204 the other end is connected with shower nozzle 202.
Described clamping mechanism comprises L-shaped connection block 112, compression spring 114 that one end is provided with step, described L-shaped connects block 112 and is flexibly connected with pedestal 102, the step end that L-shaped connects block 112 is flexibly connected driven roll wheel 108, and its other end is connected with baffle plate 104 by compression spring 114.
Described active roll 106 transverse section is zig-zag, and described driven roll wheel 108 is circumferentially provided with arc groove, it may be preferred that this arc groove diameter and printed material diameter matches.
Described material guiding pipe 3 is Teflon material, has the function of self-lubricating, is applicable to the smooth and easy transmission of various printing material, and solution prints the stifled head of material bigger effect.
In described nozzle component 2, heating member 204 is separated setting with scatterer 206, has both protected scatterer 206 from temperatures involved, it is possible to normal operation, also avoids the excessive heat radiation of scatterer 206 to cause the interference to temperature environment in heating member 204 simultaneously.
Being illustrated in figure 3 an embodiment of the present utility model, shower nozzle 202, interior pipe 208 are connected to heating member 204 two ends; During assembling, the shower nozzle 202 that is sequentially threaded, well heater 204, interior pipe 208, scatterer 206, then insert material guiding pipe 3.
Being illustrated in figure 4 another embodiment of the present utility model, shower nozzle 202, interior pipe 208 are one-body molded; During assembling, one end less for shower nozzle 202 internal diameter is thread through well heater 204, and it is connected with scatterer 206 internal thread, then insert material guiding pipe 3.
Principle of work of the present utility model:
Referring to figs. 1 through Fig. 4, after printed material (not shown) enters from feeding mouth 116, manual compression spring 114, printed material is between two roller wheels 106,108, and after unclamping compression spring 114, two roller wheels 106,108 clamp printed materials, when external impetus drives active roll 106 to move, printed material and driven roll take turns 108 also together with move, after lug boss 110, baffle plate 104, enter nozzle component 2 through material guiding pipe 3; While conveying printed material, the continuous melting of the part that printed material is in heating member 204, prints out from shower nozzle 202; Scatterer 206 above heating part 204 constantly by be radiated its inside heat conduction to context, thus avoid the printed material softening stifled head problem caused too early that is in above well heater 204.
In design of the present utility model, it is no matter a kind of shower nozzle 202 of embodiment, interior pipe 208 split design, or the one-body molded design in embodiment two, the internal diameter of preferred sprinkler 202, interior pipe 208 is equal, such material guiding pipe 3 takes heat-resisting material, such as Teflon, can directly be inserted in well heater 204, the benefit done like this, one be can avoid the printed material of material guiding pipe 3 inside and shower nozzle 202, metal material that this kind of thermal conductivity of interior pipe 208 is high directly contact, and the printed material softening problem causing blocking sprayer 202 too early occurs; Two is avoid printed material directly directly to contact, with interior pipe 208, the pollution in wide area caused, and affects it and reuses.
In the utility model, heating member 204 is mainly used in being positioned at the printed material melting of its inside, print for shower nozzle 202, heating member 204 is provided with heating tube and there is the (not shown) such as thermistor that temperature checks, for the temperature controlled in heating member 204.
These are only better embodiment of the present utility model, be not limited to the utility model, all any amendment, equivalent replacement and improvement etc. done within spirit of the present utility model and principle, all should be included within protection domain of the present utility model.
