Specific embodiment
A several preferred embodiments are named, and completely illustrate the utility model in conjunction with attached drawing to become apparent from.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of print components 1, the component include printing nozzle 11 and
One separation layer 12.Wherein, the surface of the separation layer 12 has a through-hole 121, and printing nozzle 11 is by being arranged in the through-hole 121
And it is resisted against its surface on the edge of the through-hole 121, reduce the exposed area of the printing nozzle 11.By in printing nozzle
Separation layer 12 is set on 11, in printing nozzle 11 in use, its exposed high temperature area reduces, to make from printing nozzle 11
The printed material of outflow is difficult to be attached on printing nozzle 11.
Since 121 edge of through-hole of separation layer 12 needs to contact with printing nozzle 11, so being constantly in the condition of high temperature, very
It is easily deformed or damages.In addition, 121 edge of through-hole of separation layer 12 is contacted with printing nozzle 11, it is also at the shape of relatively-high temperature
State, part printed material may be deposited on separation layer 12.Therefore, the separation layer 12 of the utility model passes through detachable
The mode of connection be connected with printing nozzle 11, consequently facilitating replacement.
The print components 1 of the utility model further include a housing 13, which is looped around the surrounding of printing nozzle 11 simultaneously
It is connect between printing nozzle 11 by dismountable mode, when the housing 13 is connected and fixed with printing nozzle 11, separation layer
12 between printing nozzle 11 and housing 13.By the way that separation layer 12 to be located between printing nozzle 11 and housing 13, make housing
13 can improve the service life of separation layer 12 from external injury by protecting insulating layer 12 when print components 1 are used.
Moreover it is preferred that as shown in figure 4, the separation layer 12 be connected by way of being detachably connected with housing 13, and
And it is fixed on the surface of the side of the housing 13 towards printing nozzle 11.The structure enables separation layer 12 and housing 13 1
It is removed with from printing nozzle 11, tears separation layer 12 open again without first removing housing 13, reduce cleaning separation layer 12 when institute
The operating procedure needed, to keep the maintenance of separation layer 12 more convenient.In the present embodiment, separation layer 12 is connected by screw 16
On housing 13, the separation layer 12 is if desired replaced, need to only remove these screws 16.In addition, in the present embodiment, housing
13 realize the fixation of the position between printing nozzle 11 also by screw, but the housing 13 of the utility model and printing nozzle 11
Between dismountable connection type be not limited in this mode for making to be screwed, in the prior art further include other solid
Determining mode may be implemented this programme, and details are not described herein.
As shown in figure 3, the print components 1 further include having cooling fan 14, the cooling fan 14 is for cooling down printing nozzle
The printed material flowed out in 11, the housing 13 have wind deflector 15, which is surrounded on separation layer 12 and is arranged and for hindering
The air-flow that gear cooling fan 14 generates blows to separation layer 12.By the way that wind deflector 15 is arranged on housing 13, it is used in cooling printing
The air-flow of material will not be blown on separation layer 12, so that the temperature of separation layer 12 and the printing nozzle being in contact with it 11 be made not drop
It is low, avoid the occurrence of printed material mobility reduce the problem of.
In order to improve the service life of separation layer 12, the frequency of replacement separation layer 12 is reduced, which also answers
This is made of heat proof material.
It is further preferable that the separation layer 12 can be used Teflon and be made.Pass through the heat-resisting quantity using Teflon, the isolation
Layer 12 the case where material modification or loss of function will not occur being close to the high-temperature components such as printing nozzle 11.Pass through utilization
The heat-insulating property of Teflon, the air-flow that cooling fan 14 generates will not take away the temperature for being isolated the printing nozzle 11 of the cladding of layer 12
And product energy consumption is caused to increase.In addition, by the non-sticky performance using Teflon, the printed material of middle outflow in printing nozzle 11
More the print quality of print components 1 will not be further promoted in the surface adhesion of separation layer 12.
In the prior art, the component on 11 periphery of printing nozzle uses high temperature resistant silica gel to be made substantially, and high temperature resistant silica gel exists
It is easy denaturation in use process, leads to the maintenance cost for occurring additional.In addition, in order to dissipate the high temperature of printing nozzle 11 will not
It loses, need to also coat heat-preservation cotton in 11 surroundings of printing nozzle and realize heat-insulation and heat-preservation.And the separation layer 12 in the utility model due to
It is made of that high temperature resistant and a variety of demands such as heat-insulated therefore can be combined, and the friction system of Teflon using Teflon
Number is lower than high temperature resistant silica gel, can preferably avoid the printed material of middle outflow in printing nozzle 11 glutinous on the surface of separation layer 12
It is attached.
The utility model also provides a kind of 3D printing equipment, which includes print components 1 as described above, by beating
It prints and separation layer 12 is set on nozzle 11, extend the service life of the 3D printing equipment printing nozzle 11 effectively.
Embodiment 2
As shown in figure 5, the utility model embodiment 2 also provides a kind of print components 1, beating in structure and embodiment 1
It is essentially identical to print component 1, the difference is that, 12 ' of separation layer of the print components 1 of the present embodiment is using material flexible
Made of matter.It therefore, should when 12 ' of the separation layer and the movement of housing connected to it 13 are mounted on printing nozzle 11
12 ' of separation layer in addition to other than the edge of through-hole 121 is fitted on printing nozzle 11, close to the surface of through-hole 121 also by
It is fitted on printing nozzle 11 in stress deformation.
If 12 ' of separation layer be rigid, may because of dimensional accuracy relationship and lead to itself and printing nozzle 11
Between can not fit closely, to make the fine gap between drill-through 12 ' of separation layer of printed material and printing nozzle 11, and attached
Be relatively isolated the other side of 12 ' of layer in printing nozzle 11, and 12 ' of separation layer in this implementation is made of flexible material, no
It will appear above-mentioned situation.
In addition, the material of 12 ' of the separation layer other than having speciality flexible, also needs to consider heat-resisting property simultaneously
Can, therefore, in the present embodiment, 12 ' of the separation layer is made of silicon rubber resistant to high temperature.
The print components make printing nozzle when in use, exposed height by the way that separation layer is arranged on printing nozzle
Warm area reduces, to make to be difficult to be attached on the printing nozzle from the printed material flowed out in printing nozzle, and effectively reduces
The printed material being deposited on printing nozzle.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the protection scope of the utility model.
