Reservation rotates, and realizes the printing of multi-angle, so as to flexibly build complicated organizational project；It can realize two kinds of biomass
The one-pass molding printing of composite material, can improve the survival rate of cell after printing, suitable for a variety of biological materials, use model
It encloses extensively.
(3) the double ejecting devices of 3D biometric prints of the invention by straight line driving mechanism, it can be achieved that nozzle level prints position
That puts freely adjusts.
The present invention is described in further detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the front view of the double ejecting devices of 3D biometric prints of the present invention.
Fig. 2 is the left view of the double ejecting devices of 3D biometric prints of the present invention.
Specific embodiment
In order to illustrate technical scheme of the present invention and technical purpose, below in conjunction with the accompanying drawings and specific embodiment is the present invention
It is further to introduce.
With reference to Fig. 1, a kind of double ejecting devices of 3D biometric prints of the invention drive including electric rotating machine 1, connecting shaft 2, straight line
Motivation structure, nozzle 5, fixed seat 8；
8 upper end of fixed seat is connected by connecting shaft 2 with the rotation axis of electric rotating machine 1；Both sides pair in the fixed seat 8
What is claimed is equipped with straight line driving mechanism；The nozzle 5 is two, is symmetricly set on the straight line driving mechanism of both sides；The straight line drives
Motivation structure can drive the horizontal linear in fixed seat 8 of nozzle 5 to slide.
In some embodiments, the straight line driving mechanism includes driving motor 4, ball-screw；The driving motor 4
Drive shaft be connected with ball-screw.The ball-screw is arranged on by two spring bearings in fixed seat 8, ball-screw
Feed screw nut is connected by ball nut with sliding block, and the nozzle 5 is fixed on sliding block.Driving motor 4 rotates, and drives ball wire
Thick stick rotates, and is further driven to nozzle 5 and moves horizontally, so as to fulfill freely adjusting for 5 horizontal print position of nozzle.
Further, above-mentioned driving motor 4 controls dc motor using PMW, the speed of motor can be carried out smooth
The adjustment of property.
As shown in Fig. 2, in other embodiment, the straight line driving mechanism includes driving motor 4, sliding block 6, slides
Rail；The driving motor 4 is linear stepping motor；Linear stepping motor is connected with sliding block 6, and the sliding rail is arranged on fixed seat 8
On, sliding block 6 coordinates with sliding rail；The nozzle 5 is fixed on sliding block 6, and driving motor band movable slider 6 is transported along sliding rail horizontal linear
It is dynamic, it is further driven to nozzle 5 and moves horizontally, so as to fulfill the adjustment of 5 print position of nozzle.
