Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained without creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute is only used in the embodiment of the present invention
In explaining relative position relation, motion conditions etc. under a certain particular pose (as shown in the picture) between each component, if should
When particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Personnel can be implemented as basis, will be understood that this technical side when the combination of technical solution appearance is conflicting or cannot achieve
The combination of case is not present, also not the present invention claims protection domain within.
The embodiment of the present invention proposes a kind of doctor assemblies, the ceramic 3D printing projected on photocuring, and can be uniform
Pave the higher printing slurry of viscosity.It will be appreciated, of course, that in remaining embodiment of the present invention, which can basis
Specific requirements are selected to any printing device and uniformly pave printing slurry, and can realize the effect of printing slurry recycling
Fruit, and it is applicable not only to the ceramic 3D printing projected on photocuring.
In an embodiment of the present invention, referring to Fig.1, the doctor assemblies include double cutting edge scraper 1, movement portion 2, Yi Jiyong
In the mounting portion 3 of installation double cutting edge scraper 1.Double cutting edge scraper 1 is installed in mounting portion 3, and double cutting edge scraper 1 is set to printing plane
The top of (not shown), mounting portion 3 are connected to movement portion 2, and movement portion 2 is by driving mounting portion 3 to move, to drive double cutting edge to scrape
Knife 1 moves and uniformly paves the printing slurry in printing plane.
Specifically, double cutting edge scraper 1 is set to the top of printing plane, and the edge plane of double cutting edge scraper 1 and printing are flat
Face is mutually parallel, to ensure double cutting edge scraper 1 when being paved to the printing slurry in printing plane, 1 energy of double cutting edge scraper
Enough slurries that will print equably tiles to the surface of printing plane, avoid the subregion of printing plane occur without print slurry or
Print the non-uniform phenomenon of slurry.Double cutting edge scraper 1 is slidably connected at by mounting portion 3 in movement portion 2, and movement portion 2 drives peace
Dress portion 3 and double cutting edge scraper 1 move along a straight line, to make double cutting edge scraper 1 be moved in a straight line above printing plane,
And the printing slurry for printing plane is uniformly paved.Further, the knot that the present embodiment double cutting edge scraper 1 passes through setting double cutting edge
Structure can carry out one-stop operation, you can uniformly pave in printing plane, beaten to improve to the printing slurry in printing plane
Efficiency and printing precision are printed, is fed without returning initial position, to improve the working efficiency of double cutting edge scraper 1；And
And extra printing slurry is focused on the knife intracavitary of double cutting edge scraper 1 by double cutting edge scraper 1, improves the utilization of printing slurry
Rate.
Preferably, it can be installed by screw between double cutting edge scraper 1 and mounting portion 3, it is easy to disassemble, consequently facilitating according to need
It asks and replaces different size, different types of blade construction, to improve the versatility of double cutting edge scraper 1.Certainly, the technology of this field
