Abstract
The invention discloses a 3D printer nozzle structure. The nozzle comprises a melting cylinder, a heating ring, and an output cylinder. The heating ring is installed on the melting cylinder and the output cylinder. The external round surface of the output cylinder is provided with a feed inlet; the feed inlet of the output cylinder is connected to the discharge hole of the melting cylinder; a rotation shaft is arranged in the output cylinder, the rotation shaft goes through one side of the output cylinder and is connected to a motor, a stirring section and a feeding section are sequentially arranged in the direction from the motor to the tail end of the rotation shaft; the stirring section is composed of a plurality of blades, and the feeding section is composed of threads. The provided 3D printer nozzle structure can improve the printed 3D model quality.
Description
Technical field
The present invention relates to 3D printer technology field, in particular to a kind of 3D printer head structure.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
Existing shower nozzle can not make wire material melt output completely due to many reasons, causes the threedimensional model poor quality of printing.
Summary of the invention
The object of the present invention is to provide a kind of 3D printer head structure, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of 3D printer head structure, comprises and melts cylinder, heating ring and output cylinder, and heating ring is arranged on and melts cylinder and export on cylinder, and it is characterized in that, the periphery of described output cylinder is provided with charging aperture, and the charging aperture exporting cylinder is connected with the discharging opening melting cylinder; Be provided with rotating shaft in described output cylinder, rotating shaft is connected with motor through exporting cylinder side, and rotating shaft is set to successively along motor to shaft end direction stirs section and feeding section; The stirring section of described rotating shaft is multiple blade, and its feeding section is screw thread.
Further, described output cylinder inwall is provided with heat-insulation layer, the too fast loss of the heat avoiding heating ring to produce.
The invention has the beneficial effects as follows, silk material enters and melts in cylinder, entering heating ring makes it melt, silk material after thawing enters output cylinder, export cylinder and continue heating, at this moment stirring vane stirs the silk material melted, and makes it be in complete molten condition fast, avoid heating that silk can not be made to expect quick and complete melting, cause the threedimensional model poor quality printed.The silk material being promoted molten condition by screw thread is exported, and avoids occurring clogging.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of 3D printer head structure provided by the invention.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
A kind of 3D printer head structure provided by the invention that Fig. 1 is shown, comprising: melt cylinder 1, heating ring, blade 3, output cylinder 4, screw thread 5, rotating shaft 7, export cylinder discharging opening 2, motor 8 and pay-off 9.Described heating ring is arranged on and melts cylinder 1 and export on cylinder 4; The periphery of described output cylinder 4 is provided with charging aperture, and the charging aperture exporting cylinder 4 is connected with the discharging opening melting cylinder 1; Be provided with rotating shaft 7 in described output cylinder 4, rotating shaft 7 is connected with motor 8 through exporting cylinder 4 side, and rotating shaft 7 is set to successively along motor 8 to rotating shaft 7 end direction stirs section and feeding section; The stirring section of described rotating shaft 7 is multiple blades 3, and its feeding section is screw thread 5.
Export cylinder 4 inwall and be provided with heat-insulation layer, the too fast loss of the heat avoiding heating ring to produce.
Silk material 10 is entered by pay-off 9 and melts in cylinder 1, entering heating ring makes it melt, silk material 10 after thawing enters and exports cylinder 4, export cylinder 4 and continue heating, at this moment stirring vane 3 stirs the silk material 10 melted, make it be in complete molten condition fast, avoid heating that silk can not be made to expect 10 quick and complete meltings, cause the threedimensional model poor quality printed.The silk material 10 being promoted molten condition by screw thread 5 is exported, and avoids occurring clogging.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
