Abstract
The utility model discloses a kind of 3D printing head, comprise nozzle and be looped around the heater element on outer nozzle wall, also comprise the materail tube of adjustable extruded material shape and size, described adjustable extruded material shape and the materail tube of size dock with the through hole of nozzle and form consumptive material and carry cavity.The beneficial effects of the utility model: shape of cross section and the size that can regulate the printing material be extruded as required.The 3D printing head equipment of the embodiment of the present application, the extruded velocity of the printing material be extruded can be regulated as required, the expand tube even clogging caused due to heating and radiating element heat conduction in the through hole of consumptive material before entering nozzle can be eliminated well, simultaneously because the solution of expand tube blockage problem, make this 3D printing head can the consumptive material of compatible various material, expand the range of choice of 3D printing consumables.
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
The consumptive material of current existing 3D printing head is imported by stainless steel through hole, as holder hollow is provided with the stainless steel through hole importing consumptive material, after 3D printing consumables is imported by this stainless steel through hole, enters into and be fused into jelly after the nozzle of heating.In order to reach good radiating effect, all fan assembly is configured with in general 3D printing device, afterwards along with the development of technology, in order to alleviate pen weight, reduce pen size, eliminate the noise that brings of fan, the radiating mode of integral fin is gradually adopted to instead of fan cooling mode in 3D printing device, general fin is arranged on around heated nozzle as being fixed on holder, to achieve good radiating effect.
But meanwhile, because heating position exists heat conduction, in addition fin position expands heat transfer scope, consumptive material is easily caused just to start expand tube in stainless steel through hole, and due to the through hole cavity of stainless steel, deformation coefficient is little, and inner wall roughness is large, very easily causes consumptive material to block in the cavity of stainless steel through hole.The design of this shower nozzle can not use the consumptive material of the materials such as PLA, seriously limits the consumptive material range of choice that 3D prints, and 3D printing device is by the shower nozzle on it simultaneously, by softening material as printing consumables or raw-food material etc., is printed on the places such as workbench.Current 3D printing device, have plenty of the specific thickness of feeding sclerosis filamentary material and by its melting or softening after, extrude (being also referred to as to extrude) by the discharging opening on shower nozzle and shaping, have plenty of and utilize preserving jar to store the material under melting or soft state and to be extruded by discharging opening and shaping.
But, shape and/or the size of these 3D printing device discharging openings are fixing, the consumptive material extruded can only be filiform or the bar of determining shape and size after curing, this also just defines the application scenario of 3D printing device, makes printing device can not adjust shape and the size of the material extruded from discharging opening in real time according to the needs printed.
Utility model content
Technical problem to be solved in the utility model is the problem of expand tube blocking overcoming defect that the shape of the material that current 3D printing device is extruded and size cannot carry out adjusting as required and certainly exist in the through hole of consumptive material before importing nozzle.
In order to solve the problems of the technologies described above, the utility model provides a kind of 3D printing head, comprise nozzle (1) and be looped around the heater element (2) on nozzle (1) outer wall, also comprise the materail tube (4) of adjustable extruded material shape and size, the materail tube (4) of described adjustable extruded material shape and size docks with the through hole of nozzle (1) and forms consumptive material and carry cavity.
The materail tube (4) of described adjustable extruded material shape and size is for fusing point is higher than the polyfluortetraethylene pipe of consumptive material fusing point or nylon tube or LCP pipe or PPS pipe.
The discharging leading portion of described nozzle (1) is provided with temperature sensor.
The beneficial effects of the utility model: shape of cross section and the size that can regulate the printing material be extruded as required.The 3D printing head equipment of the embodiment of the present application, the extruded velocity of the printing material be extruded can be regulated as required, the expand tube even clogging caused due to heating and radiating element heat conduction in the through hole of consumptive material before entering nozzle can be eliminated well, simultaneously because the solution of expand tube blockage problem, make this 3D printing head can the consumptive material of compatible various material, expand the range of choice of 3D printing consumables.
Accompanying drawing explanation
Fig. 1 is installation diagram of the present utility model;
Fig. 2 be adjustment extruded material shape and size materail tube (4) internal structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further elaborated.
A kind of 3D printing head, the heater element 2 comprising nozzle 1 and be looped around on nozzle 1 outer wall, also comprise the materail tube 4 of adjustable extruded material shape and size, the materail tube 4 of described adjustable extruded material shape and size docks with the through hole of nozzle 1 and forms consumptive material and carry cavity.
The materail tube 4 of described adjustable extruded material shape and size is fusing point higher than the polyfluortetraethylene pipe of consumptive material fusing point or nylon tube or LCP pipe or PPS pipe.
The discharging leading portion of described nozzle 1 is provided with temperature sensor.
When printing material softening during work moves in feed pipe 4.1, by the restriction of feed pipe 4.1 especially shower nozzle 4.2 hollow space and discharging opening 4.2.1 shape.Softening printing material, when discharging opening 4.2.1 extrudes, is formed and the thread or bar all identical with size with the shape of discharging opening 4.2.1 etc.That is shower nozzle 4.2 and discharging opening 4.2.1, not only has the effect transmitted softening material and extrude, and also has that to carry out cross section to softening material moulding and determine the effect of size (in other words thickness).
Shower nozzle 4.2 is provided with for carrying out the syndeton removably connected, be convenient to when needing cross sectional shape and/or the size changing the printing material be extruded, corresponding parts can be connected on shower nozzle 4.2 by the mode removably connected.
The shape of discharging opening 4.2.1 comprises circle, ellipse, triangle, rectangle or polygon.
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.
