Description
Technical field
The present invention relates to the wire squeeze assembly on a kind of 3D printer.
Background technology
3D printer is commercially more and more general, have impact on worldwide manufacturing industry revolution, can the part design production technology that places one's entire reliance upon realize in the past, and the appearance of 3D printer, this production thinking will be overturned, this makes enterprise no longer consider production technology problem when that manufactures parts, and the design of any complicated shape all can be realized by 3D printer.It is without the need to machining or mould, just directly can generate the object of any shape from computer graphics data, thus the production cycle of greatly shortened product, improve productivity ratio.Although be still left to be desired, 3D printing technique market potential is huge, certainly will become one of following manufacturing numerous break-through skill.
The general principle of 3D printer is that raw material are moulding by cooled and solidified after heating and melting, but in actual print procedure, there is outstanding problem:
In 3D is printed, easily there is plug wire in the printing head on it, in conventional design, the two ends diameter of trunnion is the same, when changing consumptive material to printer, such problem can be encountered: hold a screw plug of consumptive material silk half a day, but always can accurately not enter among trunnion, bent consumptive material silk in the process of exerting oneself, then again must extract and the silk head of press-bending is cut off, continue again to aim at trunnion with sensation and enter silk.This is a very not humane design, causes bad experience to user.
In addition, in heating for dissolving process, consumptive material easily forms blocking in trunnion inside, not only affects efficiency and the quality of printing, and can cause consumptive material loss, often needs to carry out periodic maintenance to prevent blocking, there is very large inconvenience.
Also have that cool time in print procedure, short-range missile caused moulding failed and cannot print good finished product, be easy to occur matsurface, deterioration in quality, have much room for improvement.
Summary of the invention
The object of the invention is, in order to the wire squeeze assembly provided on a kind of 3D printer, in print procedure, to solve plug wire problem, solve cooling problem simultaneously, improve printed product quality.
For achieving the above object, technical scheme of the present invention is:
Wire squeeze assembly on 3D printer, is characterized in that:
Comprise following part:
Extrude support, comprise pedestal, form symmetrically arranged guide rail hole in the both sides of described pedestal, middle part forms the screw for connecting;

Air guide structure, it comprises wind-guiding mouth and cooling fan, and described wind-guiding mouth comprises tapered mouth body, at the entrance point of described tapered mouth body, cooling fan is set, the port of export is flat tuyere, and form fixture in described entrance point side, described fixture is fixedly connected with described holder.
Do further preferably the present invention, described thermal insulation barriers Teflon pipe is made.
Do further preferably the present invention, the length of described thermal insulation barriers is at 3-7mm.
Do further preferably the present invention, described thermistor hole place is provided with fixing hole.
Compared with prior art, the present invention has following beneficial effect:
The present invention is in order to solve plug wire problem in prior art, the present invention extrudes trunnion and designs, extruding trunnion one end formation bell, this will increase the diameter of wire inlet end mouth, define a guiding port, we are when changing consumptive material silk like this, and consumptive material silk a step can enter into trunnion more smoothly under the guiding of bell, solves the problem into silk difficulty.
The present invention is provided with heating pore extruding on seat, bottoming hole is placed exactly in this hole, whole seat of extruding is heated, like this when consumptive material silk enter into extrude seat inner time, can thawing be formed, and extrude trunnion inside and be provided with thermal insulation barriers and play effect of heat insulation, stop to be delivered to extrude trunnion inside by extruding the heat produced in seat, thus reach and extrude the nonfused object of the inner consumptive material silk of trunnion, solve plug wire problem.
Simultaneously in order to can control temperature; the present invention has established fixing hole to side, thermistor hole; generally fixing hole is not set in the prior art; thermistor is caused in use to come off or drop; form normal temperature control, heating tube is in heating shape always, is fixed thermistor so place screw by fixing hole place; play and prevent from dropping, and then also just protect the normal use of hot bright resistance.
Cool down from extruder head printed material out in order to rapid, the present invention has set up an air guide structure, it comprises wind-guiding mouth, for tapered mouth body, front end is less, rear portion is larger, at rear portion, cooling fan is set, front end is flat tuyere, and this flat tuyere faces extruder head, concentrates blowout like this after wind after fan produces wind-force is blown into by rear portion through front portion, so just can delivering to nozzle position in all wind-force Unified Sets of fan, shower nozzle part material is cooled rapidly, and the product surface printed is fine and smooth, and product quality improves greatly.
The technique of testing us through our real machine solves wind-force and cools problem slowly not.What this wind-guiding mouth also made that at present our 3D printer can be beautiful prints inclined-plane and some labyrinths, can not leave any flaw on printed product surface.
As from the foregoing, in print procedure of the present invention, solve plug wire problem, solve cooling problem simultaneously, improve printed product quality.
