Abstract
The utility model discloses the feed arrangement based on 3D cakes printing semi-fluid substance, include support, the top of the support is provided with shell, the shell is hollow structure, and the upper end of the shell is provided with charging aperture, and the front portion of the shell is taper, the front end of the shell is provided with extrusion, conical screw is provided with the shell, the rear end of the conical screw is provided with motor, and the motor is rack-mount.The utility model make it that the amount of feeding is more accurate by using conical screw, and the presence of bubble in printed matter can be also reduced during propulsion, and so as to improve printing precision, and conical screw can reduce material attachment, save raw material.
Description
Technical field
It the utility model is related to the 3D printing field of a kind of 3D printing technique field, particularly food.
Background technology
3D printing extruder is that effect is FDM (Fused Deposition Modeling, technique Fused Deposition Modeling) 3D
The material transferring of printer, type of drive are generally servomotor driving, and transmission is to drive PLA (poly- breasts by the extruding of gear
Acid) or ABS (resin and plastic) wire rod, make it into heating shower nozzle printed.With the development that 3D printing technique is very fast, and
Progressively it is accepted and enters in the life of people.3D printing technique continuous ripe and advantage makes it in different necks in fact
Also good application has been obtained in domain, nowadays food service industry also becomes one new developing direction of 3D printing technique.Food at present
Category 3D printer can print the semi-fluid materials such as chocolate, batter；Because semi-fluid materials are different from PLA, ABS etc.
Solid material, thus the extrusion device of food 3D printer is different from common 3D printer, according to the viscosity of printed material not
Together, the extruder used also difference, mainly by following several：Syringe-type, plunger type, screw etc..Different extrusion dresses
Where having different advantage in putting, but there is also it is different the shortcomings that.In order to solve its weak point, and can reach more
Good using effect, therefore and design the feed arrangement of this semi-fluid substance.
The technical scheme of specific 3D printer feed arrangement has the following two kinds at present：
First, screw：Mainly by way of screw extrusion, material is by the rotation of screw rod and squeezing for container inner wall
Pressure, gradually moved to the direction of rotation of screw rod, so as to which material is got into printer head.2nd, syringe-type：With the appearance of syringe shape
Storage container of the device as material, the primary drive part by the use of the threaded long push rod matched with inside diameter of vessel as extruding, is watched
Take motor for power source, it is necessary to which multiple gears are conveyed material in a manner of extruding by the power transmission push rod of servomotor
To printing head.Wherein screw has the following disadvantages：A) sealing effectiveness is poor；B) bubble is easily produced, influences print quality；c)
Semi-fluid substance is easily adhered to its inwall, causes the difficulty of cleaning.And then there is a shortcoming in syringe-type：D) extrude stability compared with
It is low；E) rate of extrusion fluctuation is big；F) push rod impulse stroke is limited, needs to reset；Need to stop printing when g) feeding；H) container volume
It is smaller, it is impossible to accommodate enough materials.
Utility model content
The technical problems to be solved in the utility model is：A kind of new-type feed arrangement is provided, can save material and
Improve the precision of printing.
The solution that the utility model solves its technical problem is：Charging dress based on 3D cakes printing semi-fluid substance
Put, include support, the top of the support is provided with shell, and the shell is hollow structure, the upper end of the shell be provided with into
Material mouth, the front portion of the shell is taper, and the front end of the shell is provided with extrusion, conical screw is provided with the shell,
The rear end of the conical screw is provided with motor, and the motor is rack-mount.
As the further improvement of above-mentioned technical proposal, the outside of the conical screw is provided with rubber seal, the rubber
Glue sealing ring abuts with the inwall of shell.
As the further improvement of above-mentioned technical proposal, the charging aperture includes support base and hopper, the support base
It is fixed on shell, the hopper fastening is on support base.
As the further improvement of above-mentioned technical proposal, the motor is servomotor.
The beneficial effects of the utility model are：The utility model make it that the amount of feeding is more smart by using conical screw
Standard, the presence of bubble in printed matter can be also reduced during propulsion, so as to improve printing precision, and conical screw can
To reduce material attachment, raw material have been saved.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is schematic perspective view of the present utility model；
Fig. 2 is sectional view of the present utility model.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more excellent draw bail.Each technology in the invention is special
Sign, can be with combination of interactions on the premise of not conflicting conflict.
1~Fig. 2 of reference picture, based on the feed arrangement of 3D cakes printing semi-fluid substance, include support 1, the support 1
Top be provided with shell 2, the shell 2 is hollow structure, and the upper end of the shell 2 is provided with charging aperture 21, before the shell 2
Portion is taper, and the front end of the shell 2 is provided with extrusion 22, and conical screw 3, the conical screw 3 are provided with the shell 2
Rear end be provided with motor 4, the motor 4 is arranged on support 1.
Preferred embodiment is further used as, the outside of the conical screw 3 is provided with rubber seal 5, the rubber
Sealing ring 5 abuts with the inwall of shell 2.Increase by one layer of sealing ring 5 outside screw thread in feed arrangement, screw thread and device can be reduced
The space of shell so that reduce or prevent semi-fluid substance from flowing into other screw thread layers, so as to further improve the precision of charging；
