In figure, 1-motor, 2-cavity, 3-rotating disk, 4-accommodate chamber, 5-nozzle, 6-passage, 7-gear pump, 8-containment vessel, 9-
Heating plate, 31-through hole.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the printing head of a kind of 3D printer, including containment vessel, heating chamber, gear pump and nozzle.
Being provided with receiving chamber inside described containment vessel, described receiving chamber is provided with louvre, and louvre is mainly disposed to gear
Near pump, thus, when heating chamber heat production and gear pump work, the temperature accommodated in chamber also can raise, and is reduced by louvre
Temperature near gear pump, it is ensured that the normal work of gear pump.Meanwhile, as a further improvement on the present invention, it is also possible to dissipating
Increase air exhauster at hot hole, accelerate gear pump heat radiation.
Described heating chamber includes cavity, heating assembly, motor, connecting rod and rotating disk.
Described cavity uses heat-barrier material to be made as most preferably, and described cavity is positioned at the top accommodating chamber, and both pass through bolt
Or screw links together, the upper end of described cavity is provided with charging aperture, under the effect of charging aperture, it is possible to throwing raw materials, by
In the difference of 3D printer, charging aperture communicates with material storing box, or charging aperture is provided with and renovates, and being opened by renovate and being closed
Close and add raw material；The lower end of described cavity is provided with discharging opening, and under the effect of discharging opening, the raw material of thawing can pass out.
Described cavity is additionally provided with temperature sensor, thus, can examinations inside cavity by temperature sensor
Temperature, detection raw material reached fusing point.
Described motor is placed in containment vessel upper end, and the rotating shaft of described motor puts in receiving intracavity portion through containment vessel, in order to
Prevent its seepage, be added with waterproof washer in junction；Described motor is motor, thus, under the effect of motor,
Its angle that can more precisely control rotation and speed.
