Quadrangular frustum pyramid shaped is shaped as, the liquid receiving port 5 of quadrangular frustum pyramid shaped on the corresponding collecting tank 6, is provided with, the bottom of the liquid receiving port 5 is more than
The top of the liquid collection opening 4.Motor 1 is also disposed on pedestal 7, and the rotating shaft of the motor 1 connects a major axis 3.The length
One end of axle 3 is connected with the rotating shaft of motor, and the other end extend into the inside of liquid cylinder 2 through the hole I21；The liquid cylinder
2 are internally provided with fixed disk 8, and the fixed disk 8 is slightly less than the cross section of the liquid cylinder 2, and the center of the fixed disk 8 is opened
Hole II81, and the shape of hole II81 are provided with slightly larger than the cross section of the major axis 3, shape and the major axis 3 of the hole II81
Mating shapes, so that major axis 3 can pass through hole II81, and drive fixed disk 8 to follow major axis 3 to rotate together.Wherein, major axis
3 cross section is preferably regular polygon, and the shape of hole II81 is consistent with the shape of 3 cross section of major axis.In order to make major axis 3 more preferable
Fixed disk 8 is driven to rotate, the edge of hole II81 is provided with the housing 83 for stretching out, the shape of the cross section of the housing 83
It is consistent with the shape of hole II81.Pin-and-hole is provided with housing 83, on the major axis 3, fixing hole is provided with.
The concrete structure of the fixed disk 8 is as shown in Fig. 2 that multilamellar is provided with the fixed disk 8 is concentric with fixed disk
Blocker ring 82, every layer of blocker ring 82 are made up of multiple arcs piece 821, for the blocker ring 82, are arranged on identical layer
821 quantity of arc-like sheet it is identical, size is identical, and the arc-like sheet 821 is uniformly distributed around the center of circle of fixed disk 8, on different layers
Arc-like sheet 821 along fixed disk 8 radial distribution.The setting of the fixed disk is primarily on cleaning 3D printing tooth model
Resin material, therefore the distance between the blocker ring of different layers will be matched with the thickness of tooth model, be traditionally arranged to be 20mm.
On fixed disk 8, blocker ring 82 in the range of the 1/3 of 8 radiuses, is not provided with from the center of circle to fixed disk, because 8 turns of fixed disk
When dynamic, at the 1/3 of the center of circle to radius do not have enough centrifugal force to throw away the printed material sticked on tooth model.This
7 blocker rings 82 are provided with embodiment on a fixed disk 8, the material of blocker ring 82 is engineering plastics, has certain elasticity,
The tooth model of different model can be fixed.A circle is also set up in the ring near the blocker ring 82 in the center of circle of fixed disk 8 solid
Determine ring 84, the retainer ring 84 can be engaged with the blocker ring 82 near 8 circle centre position of fixed disk carrys out fixing teeth model.It is different
It can also be different that the size of the arc-like sheet 821 on layer can be identical, if the size of the arc-like sheet on different layers 821 is not
Simultaneously, then the number of degrees of the central angle corresponding to arc-like sheet 821 preferably on different layers are identicals, adjacent on so per layer
The central angle corresponding to breach between two arc-like sheets 821 is also identical, and such breach is relative could be easier by 3D
Printed material throws away.In the present embodiment, each 821 corresponding central angle of arc-like sheet is 8 °, the breach institute between two arc-like sheets
Corresponding central angle is 4 °, and 30 arc-like sheets are so provided with each blocker ring.Aperture is provided with each arc-like sheet
822, aperture 822 could be arranged to multiple, in the present embodiment, be provided with 3 apertures 822 on each arc-like sheet from top to bottom.
The fixed disk of the present invention is not limited in cleaning tooth model, can be widely applied to other moulds in 3D printing field
The recovery of the cleaning and printing resin material of type, as long as the height and blocker ring of arc-like sheet 821 is arranged according to the size of model
The distance between 82.
Additionally, in order to realize automatically controlling for device of the invention, the device of the present invention is additionally provided with controller, pressure and passes

Buzzer and warning lamp are electrically connected, as shown in Figure 3.
Wherein pressure transducer is arranged on the outer wall of liquid cylinder 2, can arrange multiple, and multiple pressure transducers uniformly set
Put on the outer wall of liquid cylinder 2, pressure transducer pressure signal at set intervals on 2 outer wall of automatic data collection liquid cylinder is simultaneously passed
Controller is passed, controller receives information and which is processed, when in 20s, when the pressure on 2 outer wall of liquid cylinder is constant,
Controller can send information to motor, and motor stops operating, because during motor rotation, major axis drives fixed disk to turn together
Dynamic, the printing resin on tooth model is subject to centrifugal forces to be thrown away, and be thrown on the stack shell of liquid cylinder, pressure transducer meeting
The pressure signal of change is collected, pressure signal does not change in 20s, illustrates that there is no longer resin continues to throw away, and tooth model is clear
It is clean to finish, therefore now motor can stop operating.Pressure transducer arranges multiple, and is evenly arranged on liquid cylinder 2,
The appearance of error can be avoided, the resin on tooth model is not cleaned and finished, motor just stopped rotation.
Wherein liquid level sensor is arranged in collecting tank 6, can gather the liquid level that resin is printed in collecting tank 6, when
When collecting tank is filled, controller sounds to buzzer and warning lamp sending signal, buzzer, warning lamp flicker, to point out more
Change collecting tank.
After the completion of tooth model is printed, taken out with clip from 3D printer, be placed in fixed disk 8 rapidly, note mould
The occlusal surfaces of teeth of type deviates from the center of circle towards the center of circle, base；Fill a fixed disk 8 right flank of liquid cylinder 2 is opened by admittedly
Determine inside disc loading apparatus, be fixed on inside liquid cylinder by major axis 3, after installing all models to be cleaned, by housing 83
Fixing hole on pin-and-hole alignment major axis 3, insertion latch prevent fixed disk 8 from axially occurring to move along long so as to fixed disk 8 is fixed
It is dynamic；The right flank of liquid cylinder 2 is closed, is sent to controller and is instructed, actuating motor is rotated, you can started cleaning and resin is returned
Knock off work.
