Abstract
The invention discloses a quick 3D (three-dimensional) printing material spraying mechanism which solves the problems that a material spraying mechanism of 3D printing equipment in the prior art sprays materials slowly, and in the prior art, wire drawing, dropping, leakage and the like occur in an intermittent printing process or after printing completion. The invention adopts the scheme that the quick 3D printing material spraying mechanism comprises a material barrel, a nozzle, a heating ring, an extrusion screw and a motor. A feeding mechanism conveys raw materials into a feeding channel. The mechanism has the advantages that the mechanism employs the extrusion screw for feeding; pressure in the material barrel is controlled by rotating speed of the extrusion screw to achieve high-speed material spraying of the nozzle; at the same time, in the printing process, in case of intermittent printing, a negative pressure interval is generated in the middle of the material barrel at the moment when the screw stops rotating; the materials at the nozzle of a spray head is not leaked outwards; and no wire drawing or dropping is generated.

3D prints the one that (3 D-printing) is RP technique, it is based on a kind of mathematical model file, use plastic or other material, gush out by squeezing with the shower nozzle of a minute nozzle and after temperature is lower than solidification temperature, starts solidification, finally form finished product by the accumulation layer by layer of plastic material, carried out the technology of constructed object by the mode successively printed.
The efficiency that 3D printing device of the prior art prints article is low, cannot printing speed article; Simultaneously 3D printing device of the prior art is in print procedure or after printing and terminating, and there will be wire drawing, tear drop and leaks the phenomenons such as material, causing the pollution of environment.
Summary of the invention
Technical problem to be solved by this invention is: slow for 3D printing device material spray mechanism of the prior art material spray speed; Simultaneously 3D printing device of the prior art is in interruption print procedure or after printing and terminating, and there will be wire drawing, tear drop and leaks the problem of the phenomenons such as material.
Design philosophy of the present invention is, adopts extrusion screw rod to carry out feedstock transportation, effectively prevents wire drawing, tear drop and leaks the generation of material phenomenon.
The object of the invention is, provide a kind of 3D fast to print material spray mechanism, this material spray mechanism adopts extrusion screw rod feeding, and material cylinder pressure is controlled by screw speed, to realize nozzle at high speeds material spray; Adopt extrusion screw rod feeding simultaneously, make in print procedure, run into and be interrupted printing, the moment that extrusion screw rod is stopping the rotation, produce between a negative pressuren zone in the middle part of barrel, the material at spray nozzle place toward excessive, can not produce wire drawing, tear drop phenomenon.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of 3D fast prints material spray mechanism, comprises barrel; The central axis of described barrel is provided with a charging hole run through completely; The barrel of described barrel one end is provided with feeding-passage; Described feeding-passage communicates with charging hole;
Nozzle is arranged on the end of the barrel other end;
Heating collar is wrapped in the periphery of barrel;
Extrusion screw rod is arranged in the charging hole on barrel; One end of described extrusion screw rod is connected with the motor driving it to rotate;
Feed mechanism transferring raw material enters feeding-passage.
Further improvement, the feeding speed of described feed mechanism and the velocity of rotation Collaborative Control of extrusion screw rod.Its essence of velocity of rotation Collaborative Control described in the present invention is, such as: motor drives extrusion screw rod to transport 1 serving material and enter barrel, so feed mechanism also must transport 1 serving material and prepares to enter, and heating collar heating simultaneously makes 1 serving material melt; Velocity of rotation Collaborative Control that Here it is.
What feed mechanism described in the present invention adopted is is applied to feed mechanism in 3D printing device or feeding mechanism in prior art, the present invention of its concrete structure does not do detailed explanation one by one.
Extrusion screw rod described in the present invention is extrusion screw rod of the prior art, and its concrete structure and course of work the present invention are not described in detail.
Nozzle described in the present invention is the nozzle be applied in prior art in 3D printing device, and its concrete structure the present invention is not described in detail.
Heating collar described in the present invention is the heating collar be applied in prior art in 3D printing device, and its concrete structure and course of work the present invention are not described in detail.
Motor in the present invention adopts motor of the prior art, motor all can meet the demands; But preferentially select driven by servomotor extrusion screw rod of the prior art to rotate in the present invention.
Compared with prior art, its beneficial effect is in the present invention:
The quick 3D of the present invention prints material spray mechanism and adopts extrusion screw rod feeding, and material cylinder pressure is controlled by screw speed, to realize nozzle at high speeds material spray; Adopt extrusion screw rod feeding simultaneously, make in print procedure, run into and be interrupted printing, the moment that extrusion screw rod is stopping the rotation, produce between a negative pressuren zone in the middle part of barrel, the material at spray nozzle place toward excessive, can not produce wire drawing, tear drop phenomenon.
