Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to the novel short range feeding that Fig. 1-Fig. 5, Fig. 1 are the 3D printers of the first embodiment that this utility model provides
Head device face structural representation；Fig. 2 is the side-looking of the novel short range feeding head device of the 3D printer in Fig. 1
Structural representation；Fig. 3 is that the dismounting of the novel short range feeding head device of the 3D printer in Fig. 1 prints head-shield and printhead
Front view after the shrouding of front side；Fig. 4 is the side-looking structural representation of the novel short range feeding head device of the 3D printer in Fig. 3
Figure；Fig. 5 is the cross-sectional view of A-A in Fig. 4.In the present embodiment, the novel short range feeding print head cartridge of 3D printer
Put and include shrouding 5 on front side of the main fixed block of inlet connector 1, printhead 2, printhead, printing head-shield 7, fan 8, motor 9, pressure arm
11, socket cap regulation screw 12, compression spring 13, feeding gear 14, U-shaped bearing 15, hexagon socket countersunk flat cap head screw 16, nozzle are fixed
Frame 17, nozzle 18, heat block 19, passage 20, thin nut 21, tooth nut 22 and fan 23.
Inlet connector 1 is threadedly attached on the main fixed block of printhead 2, and silk material (shown in accompanying drawing red line) is from inlet connector
1 enters printhead.Pressure arm 11 through the main fixed block of printhead 2 and be arranged on the main fixed block of printhead 2 groove in.Pressure arm 11
And U-shaped bearing 15 is linked together by hexagon socket countersunk flat cap head screw 16, and it is pressed in dozen by shrouding on front side of printhead 5 and bolt
In the groove of a print main fixed block 2.Feeding gear 14 is bolted on the main fixed block of printhead 2.Feeding gear 14 and U-shaped axle
Hold the gap being formed through silk material between 15.Silk material, through the main fixed block of printhead 2, is passed down through feeding gear 14 and U-shaped
Gap between bearing 15, and this gap is connected to heat block 19 by passage 20, heat block 19 connects nozzle 18.Motor 9
Rotate, make silk material carry downwards.Silk material enters heat block 19 through passage 20, extrudes from nozzle 18 after heating.Passage 20
Fastened by thin nut 21 with nozzle fixed mount 17.Tooth nut 22 is for regulating the nozzle 18 height from print platform.Fan
23 are used for heat radiation carried out above to heat block 19.Print head-shield 7 to be fixed on the main fixed block of printhead 2 by threaded screw fasteners, use
In protection, operator is not scalded by high temperature nozzle 18.Fan 8 is the heat radiation of silk material after extrusion when printer model.On front side of printhead
Shrouding 5 and the empty window printed between head-shield 7 can conveniently observe the function situation of feed mechanism.Stir with the instrument of a word cutter etc
Leveling tooth nut 22 makes to move on it or move down, thus regulates the height of respective nozzle.Head device is solid entirely through bolt
It is scheduled in printer X-axis or Y-axis.
Compression spring 13 is arranged in the hole of the main fixed block of printhead 2, and socket cap regulation screw 12 is threaded in pressure
In the lateral aperture of arm 11, socket cap one end is through in compression spring 13.Gap between feeding gear 14 and U-shaped bearing 15 is too
Time big, silk material skids and can not carry downwards.Inwardly now tighten socket cap regulation screw 12, make gap reduce, increase conveying
Frictional force.When gap between feeding gear 14 and U-shaped bearing 15 is the least, silk feed collet is too tight and causes too much powder accumulation
On feeding gear 14, the teeth groove ultimately resulting in feeding gear 14 is filled up by powder, skids and carries inefficacy.Now unscrew cylinder
Head regulation screw 12 outwards, makes gap increase, reduces the frictional force of conveying.Adjusted by the elasticity of socket cap regulation screw 12
The frictional force of joint conveying.
Wherein, fan 8 is vertically arranged with fan 23, in other embodiments, can only arrange fan 8 or only arrange wind
Fan 23, the present embodiment is only preferred embodiment.
This utility model is simultaneously suitable for single-nozzle print heads and twin-jet nozzle printhead and multiinjector head device.
Implement this utility model embodiment, have the advantages that the novel short range of 3D printer of the present utility model
Feeding head device is convenient and swift, the problem solving the regulation of printhead feed mechanism frictional force；Can conveniently observe feed mechanism
Function situation；Printhead altitude mixture control is simple, processing ease；Mechanism is simple, easily keeps in repair replacing.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
