Description
Technical field
The utility model relates to a kind of 3D printers, and in particular to a kind of 3D printer with nozzle clearing function.
Background technique
3D printer, i.e. a kind of machine of rapid prototyping technology, it is one kind based on digital model file, with powder
The adhesive materials such as last shape metal or plastics construct the technology of object by layer-by-layer printing.Past, it was often in mold
The fields such as manufacture, industrial design are used for modeling, are now increasingly used for the direct manufacture of some products.
The 3D printing technique of existing mainstream mainly includes four kinds: Stereolithography (SLA), and three-dimensional powder is bonded (3DP), choosing
Selecting property is laser sintered (SLS), fusion sediment rapid shaping (FDM).Wherein, Stereolithography technology, three-dimensional powder bonding are based on
Although the 3D printer precision of technology and Selective Laser Sintering is higher, suitable material also than wide, generally require compared with
Big power, Technical comparing is complicated, and equipment cost, maintenance cost and material cost are all very high, so application range is main at present
Concentrate on high-end manufacturing field.
Fusion sediment (Fused Deposition Modeling, FDM) is called fuse deposition, main using Filamentous hot melt
Property material as raw material, by heating and meltings, the raw material after liquefaction are squeezed by the spray head of a fine printing nozzle and are sprayed
Come.Raw material are deposited on production panel or the cured material of preceding layer after being ejected, temperature be lower than after fusing point start it is solid
Change, is successively accumulated by material and form final finished product.
During the work of FDM printer, spray head is in the condition of high temperature, and by gravity, the material of thawing can be certainly
Right slave printing nozzle leaks out, and forms waste material silk.It is generally in high temperature print state, the material of the leakage can pass through pumpback silk material
Avoid the generation of waste material silk phenomenon.But before printing (spray head temperature-rise period) and printing after (spray head desuperheating process) be cannot
It using pumpback, can not be cleared up if waste material silk is formed, and the harm of scrap is primarily present in following aspect:
1, waste material silk can reach in advance print platform than practical printed material during band draws, and be piled up in practical printing
The lower section of material causes the convex closure heaved, model accuracy is caused to decline, or even printing failure；
2, waste material silk falls off naturally from printing nozzle, is mixed into the mechanical part inside 3D printer, causes hardware damage；
3, waste material silk adheres to around printing nozzle, after long term high temperature oxidation, becomes black liquor and drops onto model surface,
Model appearance is not only influenced, is also possible to lead to plug for a long time.
Currently, most of operators mechanically remove waste material silk to eliminate above-mentioned drawback:
1, equipment directly removes waste material silk with hand or tweezers in the operating condition；
2, under the idle state of machine, spray head is preheated, using tweezers fixture non-dust cloth or paper handkerchief by waste material silk and
It cleans on spray head periphery.
Above-mentioned artificial treatment method is under equipment hot operation state, there is security risk.To solve above-mentioned ask
Topic, application No. is 201510950657.9 Chinese utility model patents to disclose a kind of 3D printer based on FDM technology,
Increase the cleaning device for being used for clear away waste silk inside equipment, which has the wiping that height is adjusted by compressed spring
Cotton can wipe waste material silk away when printing nozzle is contacted with the cleaning cotton；Application No. is 201520468321.4 China is practical
New patent discloses a kind of 3D printer spray head automatic cleaning apparatus, is internally provided with elastic component in equipment and adjusts scraping for height
Knife and the waste material box for collecting waste material, can scrape off waste material silk when printing nozzle is with the blade contact, and fall into waste material box.So
And above two manner of cleaning up, in being applied to real work, there are still certain shortcomings:
1, cleaning device does not have height adjusting function, can not be by height adjustment to Z after Wiping material is consumed
Axis is calibrated and is compensated, and cleaning device is caused to need to frequently replace Wiping material；
2, do not have perfect waste material silk processing function, though latter cleaning plant has waste material box, need waste material box
When interior waste material silk is toppled over, needs staff to protrude into hand and waste material box is removed inside equipment and is put down from printing nozzle and printing
It is taken out between platform, on the one hand, mode of operation is extremely not convenient, on the other hand, since equipment inner space is limited, in fetching process
It easily collides with other elements inside equipment, influences printing precision and service life；
3, do not have perfect printing nozzle suitable structures, in scale removal process, cleaning cotton and blade and printing nozzle end
The position correspondence at end must extremely precisely, and otherwise cleaning effect is had a greatly reduced quality, moreover, latter cleaning plant is useless since scraper is located at
The side wall of magazine, it is necessary to which single direction and scraper into contact, otherwise waste material silk can drop down above print platform, and cleaning plant then becomes
It draws a snake and add feet to it.
Utility model content
