Abstract
The utility model discloses a kind of 3D printing head, comprise shell, nozzle, the heater element be looped around on outer nozzle wall; Also comprise real time temperature and measure cover, described real time temperature is measured cover and is covered on the sharp-tongued outer wall of described nozzle.The beneficial effects of the utility model: the low heat-emissive 3D printing head that the utility model provides, it is provided with a real time temperature and measures cover on the sharp-tongued outer wall of nozzle, well solve material in the 3D printing production process come in the high torrid zone and be difficult to moulding, the mobile phenomenon of dragging silk of cooled and solidified, improve the precision that 3D prints, improve security and the comfort level of use simultaneously.
Description
Technical field
The utility model belongs to the advanced manufacture field of 3D, particularly relates to a kind of 3D printing head.
Background technology
Well-known technical grade 3D printer is very high to required precision, and the required precision of desktop level 3D printer is relatively lower, and along with the progress of technology, the required precision of desktop level 3D printer is also progressively promoting.
Traditional 3D printing head, nozzle is made with copper or high temperature ceramic material usually, and consumptive material enters into and be fused into jelly after the nozzle of heating, then realizes printing creation from the sharp-tongued output of nozzle.But in the 3D printer course of work, the sharp-tongued position that nozzle stretches out from nozzle housing is in high Warm status always, sharp-tongued outer wall externally forms a high-heating radiation district, consumptive material is molten into jelly after sharp-tongued output, in short distance high-heating radiation region, all can be subject to this high-heating radiation impact, be difficult to cooling realization fast and solidify moulding, and in shower nozzle mobile print process, be easy to formation and drag a phenomenon, have a strong impact on the precision printed.
Also similar problem is there is in 3D drawing pen, although 3D drawing pen is manual operations, do not have 3D printer high to required precision, drag a phenomenon meeting severe jamming user's creation, the control of the superhigh temperature that nozzle is sharp-tongued simultaneously easily brings constant to user, and there is certain danger.
Utility model content
The utility model object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of 3D printing head, to solve the sharp-tongued uncontrollable problem of high heat of 3D printing nozzle, with changing temperature survey cover by the straight hand operation of staff.
For solving the problem, a kind of 3D printing head, comprises shell, nozzle, the heater element be looped around on outer nozzle wall; Also comprise real time temperature and measure cover, described real time temperature is measured cover and is covered on the sharp-tongued outer wall of described nozzle.
The surrounding that described real time temperature measures cover is evenly provided with temperature sensor.
Described real time temperature measurement cover is joined individual part with nozzle and is provided with screw thread.
The top edge that described real time temperature measures cover is provided with the convex handle of knob.
Described heater element is that surface has the cylindrical of some annular grooves, and the spacing distance of each annular groove is equal.
It is funnel type that described real time temperature measures cover.
The port of export of described nozzle is provided with fixing snap ring.
The beneficial effects of the utility model: the low heat-emissive 3D printing head that the utility model provides, it is provided with a real time temperature and measures cover on the sharp-tongued outer wall of nozzle, well solve material in the 3D printing production process come in the high torrid zone and be difficult to moulding, the mobile phenomenon of dragging silk of cooled and solidified, improve the precision that 3D prints, improve security and the comfort level of use simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model 3D printing head;
Fig. 2 is the structure chart of the utility model temperature survey cover.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further elaborated.
As depicted in figs. 1 and 2, be a kind of 3D printing head, comprise shell 1, nozzle 2, the heater element 3 be looped around on nozzle 2 outer wall; It is characterized in that: also comprise real time temperature and measure cover 5, described real time temperature is measured cover 5 and covered on the sharp-tongued outer wall of described nozzle 2.
The surrounding that described real time temperature measures cover 5 is evenly provided with temperature sensor 5.1, and temperature sensor 5.1 is wrapped in the outer surface that real time temperature measures cover 5, measures operating temperature accurately.
The part that described real time temperature measurement cover 5 coordinates with nozzle 2 is provided with screw thread, facilitates real time temperature to measure the replacing of cover 5.
The top edge that described real time temperature measures cover 5 is provided with the convex handle of knob, facilitates staff's hand operation, is not scalded by the temperature survey cover 5 of high temperature.
Described heater element 3 has the cylindrical of some annular grooves for surperficial, and the spacing distance of each annular groove is equal.
It is funnel type that described real time temperature measures cover 5.
The port of export of described nozzle 2 is provided with fixing snap ring.
As depicted in figs. 1 and 2, the utility model 3D printing head comprises shell 1, nozzle 2, the heater element 3 be looped around on nozzle 1 outer wall, holder 4, real time temperature measurement cover 5.Described holder 4 hollow is provided with through hole and is fixedly installed in the cavity of shell 1, and described nozzle 2 one end is pass shell sharp-tongued, and the through hole of nozzle 2 other end docks with the through hole of holder and forms consumptive material and carry cavity.Described real time temperature is measured cover 5 and is covered on the sharp-tongued outer wall of described nozzle 2, understands operating temperature in real time by temperature sensor 5.1, ensures normally carrying out of print job.Wherein heater element 3 is the annular-heating device that PTC pottery is made, and the stacked effect of printing consumables that homogeneous heating is extruded is good.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
