Abstract
The utility model discloses a kind of 3D printer plunger pump type extrusion mechanism, including cylinder body, the upper and lower two ends of described cylinder body are provided with plunger, on described plunger, swash plate is installed, it is provided with power transmission shaft between described swash plate center bottom and cylinder body, described power transmission shaft is provided with central spring, is fixedly connected by piston shoes between described swash plate and plunger, described piston shoes both sides are also positioned at swash plate bottom and are provided with return plate, are provided with oil distribution casing on the right side of described cylinder body.By the introducing of pump type structure, making wire feed and extrusion action independent, make flow-control the most accurate, the output ironing fuse material, is more stable, it is possible to achieve synchronization carrying out of pump housing stop motion and material stopping outflow, thus solves a problem for material sialorrhea.
Description
Technical field
This utility model relates to 3D printer field, is specially a kind of 3D printer plunger pump type extrusion mechanism.
Background technology
3D prints (3D printing), the i.e. one of Rapid Prototyping technique, and it is that utilization powdery metal or plastics etc. can
Jointing material, by the multilamellar printing type (calculus) of layer upon layer, constructs null object.With Making mold, industrial design,
Build model, the existing product manufacturing that just developing into, formed " direct digitization manufacture ", some high value applications (such as hip joint or
Tooth, or some airplane components), there are the parts printed to occur.3D prints and has become as a kind of trend,
And start to be widely used in design field, especially industrial design, digital product die sinking etc., one can be completed within a few hours
The printing of grinding tool, has saved a lot of product development time to market.3D printer can print threedimensional model with various raw materials,
Using 3D Autocad, after engineers design goes out a model or prototype, that no matter design is a house or people
Work cardiac valve, is printed by the 3D printer that associated companies produces afterwards, and the raw material of printing can be organic or nothing
Machine material, such as rubber, plastics, even human organ, printing material that different printer manufacturers is provided is different.
Along with 3 D-printing machine technology develops, its application more and more extensively, the market demand increase rapidly, existing easily
Blocking；It is heated uneven；Heat block easily conducts heat to motor, causes motor excessive heating；Heat block and temperature sensor
Between transition temperature insensitive inaccurate；Dispel the heat unhappy；Extruder is existing a lot of excessively heavy, causes print speed efficiency to drop
Low；Extruder, nearly all plus exhaust fan, causes shower nozzle vibrations in print procedure to cause printer model precision to reduce；Heat block
The material easily heat being transmitted to charging aperture causes melting in advance at charging aperture resulting in blockage with charging aperture；Current extruder
Excessively complicated, it is difficult to extraction and comes；Directly perceived not, it is not easily cleaned the blockage problem caused.
Utility model content
The purpose of this utility model is to provide a kind of 3D printer plunger pump type extrusion mechanism, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, the following technical scheme of this utility model offer: a kind of 3D printer plunger pump type extruder
Structure, including cylinder body, the upper and lower two ends of described cylinder body are provided with plunger, and described plunger is provided with swash plate, described swash plate center bottom
And it is provided with power transmission shaft between cylinder body, described power transmission shaft is provided with central spring, between described swash plate and plunger, passes through piston shoes
Being fixedly connected, described piston shoes both sides are also positioned at swash plate bottom and are provided with return plate, are provided with oil distribution casing on the right side of described cylinder body.
Further, described cylinder body two ends are internally provided with the oil pocket corresponding with plunger, and bottom connects oil distribution casing.
Further, described plunger head is spherical.
Compared with prior art, the beneficial effects of the utility model are:
A kind of 3D printer plunger pump type extrusion mechanism of the present utility model, by the introducing of pump type structure, make wire feed with
Extrusion action is independent, makes flow-control the most accurate, and the output ironing fuse material is more stable, it is possible to achieve pump housing stop motion
Stop with material flowing out is synchronization carried out, thus solves a problem for material sialorrhea.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation,
Wherein, 1, plunger, 2. cylinder body, 3. oil distribution casing, 4. power transmission shaft, 5. swash plate, 6. piston shoes, 7. return plate, 8. central elastic
Yellow.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Fig. 1, a kind of technical scheme of this utility model offer: a kind of 3D printer plunger pump type extrusion mechanism, bag are provided
Including cylinder body 2, described cylinder body about 2 two ends are provided with plunger 1, and described plunger 1 is provided with swash plate 5, described swash plate 5 center bottom
And it is provided with power transmission shaft 4 between cylinder body 2, described power transmission shaft 4 is provided with central spring 8, logical between described swash plate 5 and plunger 1
Crossing piston shoes 6 to be fixedly connected, described piston shoes 6 both sides are also positioned at swash plate 5 bottom and are provided with return plate 7, set on the right side of described cylinder body 2
It is equipped with oil distribution casing 3.
Described cylinder body 2 two ends are internally provided with the oil pocket corresponding with plunger 1, and bottom connects oil distribution casing 3.
Described plunger 1 top is spherical.
In sum, this utility model introducing by pump type structure, make wire feed independent with extrusion action, make flow-control
The most accurate, the output ironing fuse material, is more stable, it is possible to achieve pump housing stop motion and material stop the same stepping flowed out
OK, thus solve a problem for material sialorrhea.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
