Following will be combined with the drawings in the embodiments of the present invention, is carried out to the technical solution in inventive embodiments clear, complete
Ground describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, shall fall within the protection scope of the present invention.
Reference explanation book attached drawing, a kind of 3D printing ejecting device, including sleeve (10) are provided on the sleeve (10)
Feed inlet (15) is provided at least one section of heating device (20) on the periphery wall of the sleeve (10), the sleeve (10)
One end is provided with nozzle (30), and the other end of the sleeve (10) is provided with motor (40), spiral shell is provided in the sleeve (10)
Bar (50), the screw rod (50) are connected with motor (40), and a kind of 3D printing of the present invention is applied to 3D printing skill with ejecting device
It in art, is specifically used as the printing head of 3D printer, printing raw material enters from feed inlet (15) in sleeve (10), in spiral shell
Under the turning effort of bar (50), printing raw material is to movement at nozzle (30), and in the process of moving, printing raw material is by heating device
(20) heat effect melting, then sprayed from nozzle (30), using the above structure, 3D printing precision is significantly improved.
Further, the heating device (20) includes temperature detector and heating collar, and the temperature detector, which can be experienced and feed back, to be added
The temperature level of heat, the heating collar is used to print the heating of raw material, as heating source.
Further, the heating collar can be according to the different heating temperature of the different set of reaction raw materials, the heating
Temperature is adjustable, improves the flexibility of this ejecting device application, makes any material that can be as 3D printing raw material, can pass through this
Ejecting device is melted.
Further, the screw rod (50) is fitted close with sleeve (10), and the screw rod (50) excludes sleeve by rotation
(10) interior gas, and print raw material for sleeve (10) inner wall, screw channel bottom surface, spiral shell rib pressure surface and printing raw material and beat
Friction and mutually movement can be all generated between print raw material, the combination of above-mentioned movement makes printing raw material be promoted to nozzle.
Further, four sections of heating collars are provided on the sleeve (10), the setting of the multistage heating circle can be independent
Heating melting, keeps printing raw material more various in the selection of type, and can promote melting effect.
Further, the motor (40) be micro numerical motor, the motor (40) in order to control screw rod (50) rotation
Driving device, screw rod (50) stop operating, and nozzle (30) stops discharging, the micro numerical motor energy cramped construction and guarantee turn
Fast is certain, so that printing raw material is melted more uniform, promotes printing precision.
Further, an expansion mouth (155) is provided on the feed inlet (15), the expansion mouth (155) keeps printing former
The selection of material state has more flexibility, can select graininess, powdered, strip etc. are any can enter by expansion mouth (155)
Material in sleeve (10) solves unicity problem that can only be using wire rod as printing raw material.
In use, the feed inlet (15) can connect a conveying device, by print raw material mechanization conveying into
In sleeve (10), storage device can also be set, printing raw material is made to uniformly enter in sleeve (10), it is flexible multi-purpose, into set
Printing raw material in cylinder (10) is constantly mobile to nozzle (30) under the promotion that screw rod (50) rotates, and enters set in printing raw material
After in cylinder (10), heating device (20) prints raw material in the process of moving simultaneously according to adjusting the temperature set to carry out heat effect
Heated to be melted, finally from nozzle (35) output on nozzle (30), the rotation of the screw rod (50) passes through micro numerical electricity
The control of machine drives, and realizes operating；When motor (40) stop, screw rod (50) stops operating, and nozzle (30) stops discharging, if place
In the stagnation of long period, micro numerical motor can control screw rod (50) counter-rotating certain angle, avoid printing raw material because of length
The stagnation of time and the problem of overflow, lead to roughness of machining surface.
It is usually 10-20cm, diameter in whole height by the size Control of ejecting device to coordinate the use of printer
