The flexible consumptive material extrusion device of a kind of 3D printer, comprise Teflon block, pay-off, guide entrance, material channel and stepper motor, the middle part of Teflon block is located at by described pay-off, and pay-off comprises material extrusion bearing and material extrusion gear, and material extrusion gear is connected with the rotating shaft of stepper motor; This Teflon block described and material extrusion gear are installed on stepper motor; Material channel is provided with between described material extrusion gear and material extrusion bearing; Described guide entrance is located at the below of pay-off; The flexible consumptive material extrusion device of this FDM type 3D printer moves cooperation material extrusion bearing by flexible consumptive material feeding guide entrance by the flexible consumptive material of material extrusion gear driven along shear force direction, then enter nozzle to print, solve the problem that FDM type 3D printer prints flexible consumptive material; This product expands the scope of FDM type 3D printer in practical application, reduces the processing request to flexible consumptive material, reduces consumptive material production cost, greatly facilitate the development of FDM type 3D printer.
Description
Technical field
The utility model relates to 3D printing technique field, the flexible consumptive material extrusion device of especially a kind of FDM type 3D printer.
Background technology
Current 3D prints and mainly uses powdery metal or plastics etc. the mode that successively prints of jointing material can carry out the technology of constructed object, and the object hardness printed is all higher, can not build soft object, thus must limit bringing of 3D print application.
Utility model content
The utility model aims to provide and a kind ofly expands the scope of FDM type 3D printer in practical application, decrease the processing request to flexible consumptive material, reduce the cost of consumptive material raw materials for production, greatly facilitate the flexible consumptive material extrusion device of FDM type 3D printer of the development of FDM type 3D printer.
For achieving the above object, the utility model provides following technical scheme: the flexible consumptive material extrusion device of a kind of 3D printer, comprise Teflon block, pay-off, guide entrance, material channel and stepper motor, the middle part of Teflon block is located at by described pay-off, pay-off comprises material extrusion bearing and material extrusion gear, and material extrusion gear is connected with the rotating shaft of stepper motor; This Teflon block described and material extrusion gear are installed on stepper motor; Material channel is provided with between described material extrusion gear and material extrusion bearing; Described guide entrance is located at the below of pay-off.
As further scheme of the present utility model: be provided with gap between described material extrusion bearing and material extrusion gear.
As further scheme of the present utility model: the position of described guide entrance is near pay-off.
As further scheme of the present utility model: so the material of guide entrance is Teflon.
Compared with prior art, the beneficial effects of the utility model are: the flexible consumptive material extrusion device of this FDM type 3D printer moves cooperation material extrusion bearing by flexible consumptive material feeding guide entrance by the flexible consumptive material of material extrusion gear driven along shear force direction, then enter nozzle to print, solve the problem that FDM type 3D printer prints flexible consumptive material; This product expands the scope of FDM type 3D printer in practical application, decreases the processing request to flexible consumptive material, reduces the cost of consumptive material raw materials for production, greatly facilitate the development of FDM type 3D printer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, the flexible consumptive material extrusion device of a kind of 3D printer, comprise Teflon block 1, pay-off 2, guide entrance 5, material channel 6 and stepper motor 7, the middle part of Teflon block 1 is located at by described pay-off 2, pay-off 2 comprises material extrusion bearing 3 and material extrusion gear 4, and material extrusion gear 4 is connected with the rotating shaft of stepper motor 7, is provided with gap between material extrusion bearing 3 and material extrusion gear 4; This Teflon block 1 described is installed on stepper motor 7 with material extrusion gear 4; Be provided with material channel 6 between described material extrusion gear 4 and material extrusion bearing 3, flexible consumptive material 21 enters between material extrusion gear 4 and material extrusion bearing 3 through material channel 6, drives flexible consumptive material 21 to move along shear force direction carry out guide entrance 5 by material extrusion gear 4; Described guide entrance 5 is located at the below of pay-off 2, its position is near pay-off 2, because flexible consumptive material 21 is softer, after passing through pay-off 2, flexible consumptive material 21 will enter guide entrance 5, and between guide entrance 5 and pay-off 2, flexible consumptive material 21 easily bends, thus cause getting stuck, so guide entrance 5 must near the periphery of pay-off 2; When flexible consumptive material 21 is extruded by nozzle, flexible consumptive material 21 between gear and nozzle will bear extruding force, this section of flexible consumptive material 21 will bend, reduce extruding force and arrive nozzle, the consumptive material of hot melt is not easily extruded, so the diameter of guide entrance 5 must be greater than the 0.15mm (positive and negative 0.05mm) of consumptive material diameter; Flexible consumptive material 21 is when entering guide entrance 5, and guide entrance 5 adds and has sharper acute angle man-hour, and guide entrance 5 is smaller, snaps into flexible consumptive material 21 than being easier to, so the material Teflon that guide entrance 5 is processed goes to overcome the above problems; Another one benefit is also had to be that after guide entrance 5 is processed, inwall can be very smooth and have lubricity like this.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
