The present invention provides a kind of 3D printing nozzle, including shell, nozzle, the heater element being looped around on outer nozzle wall；Real time temperature measurement cover is further included, the real time temperature measurement cover is covered on the sharp-tongued outer wall of the nozzle.Beneficial effects of the present invention：Low heat-emissive 3D printing nozzle provided by the invention, it is provided with a real time temperature measurement cover on the sharp-tongued outer wall of nozzle, it solves material in the 3D printing production process that high fever is brought well and is difficult to that cooled and solidified is moulding, mobile the phenomenon that dragging thread, the precision of 3D printing is improved, while improves the security and comfort level used.
Description
Technical field
The invention belongs to 3D advanced manufacturing field more particularly to a kind of 3D printing nozzles.
Background technology
It is known that technical grade 3D printer is very high to required precision, the required precision of desktop grade 3D printer is opposite will
Lower, with advances in technology, the required precision of desktop grade 3D printer is also stepping up.
Traditional 3D printing nozzle, usually made of copper or high temperature ceramic material, consumptive material is entered by adding nozzle
Jelly is fused into after the nozzle of heat, then realizes printing creation from the sharp-tongued output of nozzle.However in the 3D printer course of work,
Nozzle is constantly in high Warm status from the sharp-tongued position that nozzle housing stretches out, and sharp-tongued outer wall externally forms a high-heating radiation area,
Consumptive material is molten into jelly after sharp-tongued output, can all be influenced in short distance high-heating radiation region be subject to this high-heating radiation,
Realize that solidification is moulding it is difficult to be quickly cooled down, and in nozzle movement print procedure, it is easy to a phenomenon is dragged in formation, is seriously affected
The precision of printing.
There is also similar problem in 3D drawing pens, although 3D drawing pens are manual operationss, there is no 3D to required precision
Printer is high, but drag a phenomenon can severe jamming user a creation, while user is easily given in the control of the sharp-tongued superhigh temperature of nozzle
Bring constant, and there are certain danger.
The content of the invention
The object of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of 3D printing nozzle, with solution
The certainly uncontrollable problem of the sharp-tongued high fever of 3D printing nozzle, the same straight hand operation of staff that can pass through replace temperature survey
Cover.
To solve the above problems, a kind of 3D printing nozzle, including shell, nozzle, the heater being looped around on outer nozzle wall
Part；Real time temperature measurement cover is further included, the real time temperature measurement cover is covered on the sharp-tongued outer wall of the nozzle.
Temperature sensor is uniformly provided with around the real time temperature measurement cover.
The real time temperature measurement cover is equipped with screw thread with nozzle with a part.
The top edge of the real time temperature measurement cover is equipped with knob lug.
The heater element has the cylinder of several annular grooves, the spacing distance phase of each annular groove for surface
Deng.
The real time temperature measurement cover is funnel type.
The port of export of the nozzle is equipped with fixing clasp.
Beneficial effects of the present invention：Low heat-emissive 3D printing nozzle provided by the invention, on the sharp-tongued outer wall of nozzle
There is provided real time temperature measurement cover, solve well material in the 3D printing production process that high fever is brought be difficult to cool down it is solidifying
Gu moulding, mobile the phenomenon that dragging thread, the precision of 3D printing is improved, while improves the security and comfort level used.
Description of the drawings
Fig. 1 is the structure diagram of 3D printing nozzle of the present invention；
Fig. 2 is the structure chart of temperature survey cover of the present invention.
Specific embodiment
The invention will be further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, it is a kind of 3D printing nozzle, including shell 1, nozzle 2, is looped around adding on 2 outer wall of nozzle
Thermal device 3；It is characterized in that：Real time temperature measurement cover 5 is further included, the real time temperature measurement cover 5 is covered in the nozzle 2
On sharp-tongued outer wall.
Temperature sensor 5.1 is uniformly provided with around the real time temperature measurement cover 5, temperature sensor 5.1 is wrapped in reality
When temperature survey cover 5 outer surface, accurately measure operating temperature.
The real time temperature measurement cover 5 is equipped with screw thread with the part that nozzle 2 coordinates, and facilitates real time temperature measurement cover 5 more
It changes.
The top edge of the real time temperature measurement cover 5 is equipped with knob lug, facilitates staff's hand operation, not by high temperature
Temperature survey cover 5 scald.
The heater element 3 has the cylinder of several annular grooves, the spacing distance phase of each annular groove for surface
Deng.
The real time temperature measurement cover 5 is funnel type.
The port of export of the nozzle 2 is equipped with fixing clasp.
As depicted in figs. 1 and 2,3D printing nozzle of the present invention includes shell 1, nozzle 2, is looped around adding on 1 outer wall of nozzle
Thermal device 3, fixed seat 4, real time temperature measurement cover 5.The fixed seat 4 is hollow to be equipped with through hole and is fixed at the chamber of shell 1
In vivo, described 2 one end of nozzle is be pierced by shell sharp-tongued, and the through hole of 2 other end of nozzle docks to form consumption with the through hole of fixed seat
Material conveys cavity.The real time temperature measurement cover 5 is covered on the sharp-tongued outer wall of the nozzle 2, real by temperature sensor 5.1
When understand operating temperature, ensure being normally carried out for print job.Wherein heater element 3 is ring heater made of PTC ceramics
Part, it is good that the printing consumables that homogeneous heating squeezes out is stacked effect.
Those of ordinary skill in the art will understand that the embodiments described herein, which is to help reader, understands this hair
Bright principle, it should be understood that protection scope of the present invention is not limited to such special statement and embodiment.This field
Those of ordinary skill these disclosed technical inspirations can make according to the present invention and various not depart from the other each of essence of the invention
The specific deformation of kind and combination, these deform and combine still within the scope of the present invention.
