Description
Technical field
The present invention relates to a kind of 3D printers, and in particular to a kind of wire feed of the 3D printer of adjustable far and near journey transmission mode
Heating device.
Background technique
3D printing technique appears in the 1980s, also referred to as " rapid shaping technique ".Its biggest advantage is that nothing
It need to be machined or grinding tool, directly any object can be generated from the graph data that Computer Design goes out, to greatly contract
The R&D cycle of short sawn timber improves productivity and reduces production cost.Therefore art circles and industry are widely used in.3D
Printing technique can be divided into stereolithography (SLA), laminated solid mass manufacture (LOM), selectivity according to the difference of its forming method
Laser sintered (SLS), Fused Deposition Modeling (Fused Deposition Modeling, FDM) etc..Wherein FDM rapid shaping system
System is that it does not use laser system with the most essential difference of other systems, therefore cost is minimum, is also presently the most extensive
A kind of 3D printing technique of application.FDM technique is usually that solid low melting point filiform printed material is heated to semi-molten state,
Such as PLA or ABS.Then, it is squeezed out, according to every layer of scheduled track of institute of object, is successively manufactured, one layer of workbench of every manufacture
Decline a thickness or printing head rises a thickness, finally constructs entire entity repeatedly.
The wire feed heating device of 3D printer includes wire feeder and heating nozzle, and wire feeder is by Filamentous printed material
It is gradually transferred to heating nozzle, is sprayed after being heated by heating nozzle, traditional wire feeder is divided into according to the difference of mode of movement
Long-range wire feeder and two kinds of short range wire feeder, both short range wire feeder and heating nozzle direct-assembling are relatively remote to send
Silk mechanism squeezes out more accurate, convenience of reloading, lower to the torque requirement of extruder motor, and long-range wire feeder and heating nozzle
The two is connected by pipeline, wire feeder and the separated state of heating nozzle, opposite short range wire feeder, heating nozzle inertia
Small, running fix is more accurate, and print speed is fast, maintains easily, thus the two have the advantages that it is respective, suitable for different fields
It closes, however the wire feeder of the two transmission mode cannot mutually switch, and the scope of application of the wire feeder of single structure is caused to have
Limit.
In addition, heating nozzle mainly include feeding pipes, the aluminium alloy heat block for being set to feeding pipes outer end, with
And the nozzle for being fixed on aluminium alloy heat block and being connected to feeding pipes conveying, wherein be arranged on aluminium alloy heat block useful
In the heating unit of heating.When printing, silk material send into aluminium alloy heat block heated thawing from by wire feeder, then from nozzle
Outflow.The diameter of nozzle determines the diameter of wire vent, this just determines that the maximum gauge of the synusia of printing can not be greater than nozzle
Diameter.It is well known that 3D printing technique is realized by the thought of layering, and in general, synusia thickness is thicker, model surface precision
It is poorer, but the print time is shorter.Synusia thickness is thinner, and model print surface precision is higher, but the print time is longer, meanwhile, 3D
The speed of printer head movement is limited by rate of material dissolution and nozzle diameter.Currently, the nozzle diameter of 3D printer exists
Between 0.1 to 0.5 mm, to avoid the too small plug of nozzle diameter, most of printers use the nozzle of 0.4 mm diameter.If
Want to print finer model, it will usually select nozzle diameter lesser, but will increase print time and plug simultaneously in this way
Risk.
In 3D printing process, usual certain models are not needed completely using unified thickness, than as shown in Fig. 1
Dumbbell shape small size nozzle can be used in the obvious place of profile variations to take into account process time and processing progress
Printing.And change unconspicuous, large scale nozzle print can be used.Model quality not only can be improved in this way but also can reduce and beaten
Print time and cost.But the replacement of the nozzle of traditional 3D printer needs would be attached to the nozzle of alloy heat block bottom
Entirety screws down, and before a model has not printed, can not replace another nozzle, and replaced nozzle and also need
Re-calibrate the distance between nozzle and print platform.Therefore very troublesome, efficiency is very low.It is therefore desirable to be changed to this
Into.
Pass through retrieval:
(1) China Patent Publication No. CN105109041A discloses a kind of 3D printer of interchangeable nozzle printing, the technology
Scheme changes the nozzle structure of the 3D printer of traditional FDM technique completely, and additional setting guide rail is needed to be driven,
This structure can not be suitable for 3D printer transformation very universal currently on the market.
(2) China Patent Publication No. CN105965898A discloses a kind of 3D printer spray head of rotatable switching, the skill
The rotation of the printer head of art scheme needs such as to switch over manually by external force, substantially replaces with traditional craft
Printer nozzle is without too different, and mostly important, which cannot achieve the function that real-time nozzle switches in real time automatically
Energy.
