Abstract
The invention provides an extrusion device of a 3D printing pen. The extrusion device comprises an extrusion cylinder arranged between a penholder and a pen nozzle. An extrusion chamber is formed in the extrusion cylinder, communicates with the pen nozzle, and is internally provided with a heater for fusing a pen core and a spiral conveying assembly for conveying the fused pen core. The spiral conveying assembly comprises a rotating shaft and spiral blades arranged on the rotating shaft. One end of the rotating shaft extends into the pen nozzle, and the other end of the rotating shaft is connected to a motor located outside the extrusion chamber through a connecting rod. The motor is fixed in the penholder through a support. According to the invention, firstly the heater is utilized to heat and fuse the pen core; then the spiral blades are driven by the motor to convey the fused pen core to the pen nozzle; and finally the fused pen core is extruded from the pen nozzle. The extrusion device of the 3D printing pen is simple in structure, ingenious in design, and stable and reliable in effect, and is easy to carry out.
Description
Technical field
The invention belongs to 3D printing device technical field, be specifically related to the extrusion device that a kind of 3D prints pen.
Background technology
3D prints and is also rapid shaping, is a kind of novel industrial processing technology, and for plastic material, the principle that 3D prints is generally is undertaken melting rear ejection by plastics, and the material cooled after ejection solidifies moulding needed for rear formation.3D print system for industrial processes is comparatively complicated.3D being printed principle is applied on the paintbrush of small-scale structure, makes paintbrush realize simple 3D printing function.3D prints pen and not only increases the interest of paintbrush product, simultaneously can also the design show of Computer Aided Design personnel.But the inner space printing pen due to 3D is less, therefore design structure simple, the good extrusion device extruding effect can be met again extremely important simultaneously.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provides a kind of 3D to print the extrusion device of pen.This apparatus structure is simple, is skillfully constructed, and effect stability is reliable, easy to implement.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of 3D prints the extrusion device of pen, it is characterized in that: comprise the extruded tube be arranged between penholder and a mouth, extruding cavity is offered in described extruded tube, described extruding cavity is connected with a mouth, the heater for melting pen core and the helical feed assembly for transporting molten pen core is provided with in described extruding cavity, described helical feed assembly comprises rotating shaft and is arranged on the helical blade in rotating shaft, one end of described rotating shaft is stretched in a mouth, the other end of described rotating shaft is connected with the motor be positioned at outside extruding cavity by connecting rod, described motor is fixed in penholder by support.
In the present embodiment, the shape of described extruding cavity is horn-like.
The present invention compared with prior art has the following advantages:
First the present invention utilizes heater by pen core heating and melting, and then utilize motor to drive helical blade, thus melting pen core is delivered to a mouth, finally extruded by a mouth, structure is simple, is skillfully constructed, and effect stability is reliable, easy to implement.
Below in conjunction with drawings and Examples, the present invention is described in further detail.

Detailed description of the invention
As shown in Figure 1, the extrusion device that 3D of the present invention prints pen comprises the extruded tube 2 be arranged between penholder 10 and a mouth 9, extruding cavity 3 is offered in described extruded tube 2, described extruding cavity 3 is connected with a mouth 9, the heater 7 for melting pen core 1 and the helical feed assembly for transporting molten pen core 1 is provided with in described extruding cavity 3, the helical blade 8 that described helical feed assembly comprises rotating shaft 11 and is arranged in rotating shaft 11, one end of described rotating shaft 11 is stretched in a mouth 9, the other end of described rotating shaft 11 is connected with the motor 4 be positioned at outside extruding cavity 3 by connecting rod 6, described motor 4 is fixed in penholder 10 by support 5.
In the present embodiment, the shape of described extruding cavity 3 is horn-like.
The course of work that 3D of the present invention prints the extrusion device of pen is: when pen core 1 is sent into after in extruding cavity 3, heater 7 in extruding cavity 3 is by pen core 1 heating and melting, then motor 4 is utilized to drive helical blade 8 to rotate around rotating shaft 11, melting pen core 1 is delivered in a mouth 9 under the turning effort of helical blade 8, extrudes eventually through a mouth 9.
The above is only preferred embodiment of the present invention, not imposes any restrictions the present invention.Every above embodiment is done according to invention technical spirit any simple modification, change and equivalence change, all still belong in the protection domain of technical solution of the present invention.
