Abstract
The utility model discloses a device of 3D print needle and feed cylinder, including feed cylinder and connection the syringe needle of feed cylinder, the syringe needle includes outer needle head and fixed the setting the hollow structure's of the inside position placed in the middle of outer needle head interior syringe needle, the one end of interior syringe needle with the first opening part of outer needle flushes, and the other end links to each other with the syringe needle coupling hose who is located the feed cylinder, and the interior syringe needle coupling hose other end communicates with each other with the external world outside extending to the opening of feed cylinder lateral wall. The utility model discloses the hollow structure's of the various shapes of printable fibre to can add an other material through inside syringe needle in the fibrous while of printing, thereby add other materials in hollow structure, the realization has printing in step around two kinds of materials of structure.
Description
Technical field
This utility model belongs to 3D printing technique field, specifically a kind of printable hollow
The fiber of structure, and 3D printing syringe needle and the dress of barrel of other materials can be added in the fibre
Put.
Background technology
3D printing technique makes again increasing material prepare, and is the field of Recent study more hot topic, he
It is that the method by addition prints stereochemical structure.Be widely used at present organic and inorganic and
Prepared by the 3D of metal material.The most conventional 3D prints syringe needle can only print solid construction
Fiber, it is impossible to realize the printing of hollow structure fiber, and can not be at fibre while printing fiber
Dimension is internal adds other materials.
Utility model content
The 3D that the utility model proposes a kind of printable hollow structure prints syringe needle and is connected
The cylinder device connect, can realize the printing of hollow structure 3D fiber, and can be while printing
Other material is added in hollow structure.
This utility model adopts the following technical scheme that realization:
A kind of 3D prints syringe needle and the device of barrel, including barrel and the pin that connects described barrel
Head, described syringe needle includes outer syringe needle and is fixedly installed in described outer needle wall middle position
The interior syringe needle of hollow structure, one end of described interior syringe needle flushes with described outer syringe needle opening part, another
End is connected flexible pipe and is connected with the syringe needle being positioned at barrel, and interior syringe needle connects the flexible pipe other end and extends
Outside the opening of barrel sidewall, communicate with the external world.
Further, described outer syringe needle and interior syringe needle are integral type structure.
Further, the fixing device for fixing described interior syringe needle it is provided with in described outer syringe needle.
Further, the exit shape of cross section of described interior syringe needle be circular, oval or
Polygon, it is possible to for other arbitrary shapes, thus print the hollow structure of various form.
Further, described outer syringe needle and interior needles materials are metal or plastics.
Compared to existing technology, this utility model can realize the printing of hollow structure fiber, and hollow is tied
Structure can be effectively improved mechanical performance, and can reduce weight.Interior syringe needle can be while printing
Synchronize to add other material, and be wrapped in circular fiber, it is achieved the biphase printing of fiber.
Accompanying drawing explanation
Fig. 1 is the structural representation of barrel and syringe needle.
Fig. 2 is syringe needle vertical section enlarged diagram.
Fig. 3 is cross sectional representation at A-A in Fig. 2.
It is: 1-barrel that in 2-, syringe needle connects flexible pipe shown in figure, the outer syringe needle of 3-, syringe needle in 4-,
5-fixing device.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to of the present utility model wherein one
The structure of the situation of kind is described in detail.Obviously, the present embodiment is only one of the present utility model
Situation, and not all.
As it is shown in figure 1, a kind of 3D prints syringe needle and the device of barrel, including barrel 1 and company
Connecing the syringe needle of described barrel 1, described syringe needle includes outer syringe needle 3 and is fixedly installed on described outer pin
The interior syringe needle 4 of the hollow structure of 3 interior central positions, one end of described interior syringe needle 4 and institute
Stating outer syringe needle 3 opening part to flush, the other end is connected flexible pipe 2 with the syringe needle being positioned at barrel 1
Being connected, interior syringe needle connects outside the opening that flexible pipe 2 other end extends to barrel 1 sidewall, with the external world
Communicating, the opening of barrel 1 sidewall can be according to the specific requirement of equipment, and opening can be arbitrary in sidewall
Position.
Described barrel 1 is made up of rigid plastics, arranges an opening, inwardly at upper portion side wall
In connecting, syringe needle connects flexible pipe 2, outwards can connect other equipment for feeding.Interior syringe needle connects
Length extended barrel 1 bottom of flexible pipe 2 connects the opening of interior syringe needle 4.Outer syringe needle 3 and interior
Syringe needle 4 uses the split-type structural of separately preparation, and interior syringe needle 4 is the hollow pipe of stainless steel,
Outer syringe needle 3 is plastic construction.After interior syringe needle 4 is connected flexible pipe 2 connection with interior syringe needle, outside insertion
Fixing device 5 within syringe needle 3, and flush at lower ending opening, such as Fig. 2 with outer syringe needle 3
Shown in, in this example, the fixing device 5 of fixing interior syringe needle 4 is enclosed in centre by four plastic sheets
Hollow pipeline Fig. 3 of syringe needle 4 in becoming one just to accommodate, plays the effect of fixing interior syringe needle 4,
Finally outer syringe needle 3 is fixed on barrel 1 by knob, the exit of described interior syringe needle 4
Shape of cross section is circular, oval or polygon, such as triangle, square etc., but not
It is limited to these shapes.
During printing, in barrel 1 add slurry, by air pressure by slurry inside and outside syringe needle it
Between extrude.If barrel 1 sidewall and flexible pipe 2 connecting place are not connected to other equipment, then print
Fiber is hollow structure；Can be to flexible pipe if barrel 1 sidewall and flexible pipe 2 connecting place are connected to other
The equipment of interior charging, can print out the fiber with inside and outside two kinds of materials, forms a kind of material ring
Cincture fiber around another kind of material.
Above-described embodiment of the present utility model is only to be made by clearly demonstrating this utility model
Citing, and be not the restriction to embodiment of the present utility model.For art
For those of ordinary skill, other multi-form can also be made on the basis of the above description
Change or variation.Here without also cannot all of embodiment be given exhaustive.All in this reality
With any amendment, equivalent and the improvement etc. made within novel spirit and principle, all should
Within being included in this utility model scope of the claims.
