Before powder collecting region.
It can also be by under main part 10 it should be understood that the cleaning backing plate 100 is installed on 3D printer
Hook, the overshooting shapes structure such as pillar are set on surface 102, correspondingly, before the powder collecting region of 3D printer setting hook slot,
The sunk structures such as accommodation groove will be linked up with, and the overshooting shapes structure such as pillar and hook the sunk structures such as slot, accommodation groove and cooperate, make
The cleaning backing plate 100 is obtained to be installed on 3D printer.
It is uniformly arranged several lug bosses 22 on the upper surface 101 of the main part 10, several lug bosses 22 are along Y-direction
Several rows of setting spaced apart, 22 quantity of lug boss of adjacent two rows are inconsistent.That is first row lug boss 20 and second row
21 quantity of lug boss is inconsistent, and the quantity of first row lug boss 20 is that three lug bosses, second row is arranged towards X-direction interval
The quantity of lug boss 21 is that two lug bosses are arranged towards X-direction interval.First row lug boss 20 and second row lug boss 21
It shifts to install.
It should be understood that the quantity of the first row lug boss 20 and second row lug boss 21 can also be identical, this implementation
Mode does not make any restrictions to the quantity of lug boss 22.
In present embodiment, several lug bosses 22 are semicircular arc convex, are provided projectingly towards Z-direction
In on the upper surface 101.
It should be understood that several lug bosses 22 can also for other shapes, such as semicircle plate-like, strip etc. other
Arbitrary shape, present embodiment do not make limitation to the shape of lug boss 22.
It is understood that the lug boss 22 can also be and be protrudingly placed on a specific pattern on the upper surface 101, such as
The other arbitrary shapes such as bow font, zigzag, the S-shaped being provided projectingly are formed on the upper surface 101, present embodiment is not to convex
Portion 22 is played to be formed by specific pattern and make limitation.
Referring to figure 2., the scraper plate 200 includes scraping article 201, and the scraping article 201 is arranged in 200 one end of scraper plate,
Driving device such as motor driving scraper plate moves back and forth on shaped region.In present embodiment, the scraping article 201 is rubber material
Material, when the scraper plate 200 is moved to cleaning 100 top of backing plate, the scraping article 201 is contacted on the cleaning backing plate 100
Several lug bosses 22, the scraping article 201 mutually supports with several lug bosses 22, and the scraping article 201 can generate flexibility
Deformation, in this way, the metal powder agglomerate being sticked on the scraping article 201 can be destroyed, be metal powder agglomerate and scraper plate
200 separation, it is ensured that do not powder away during old-fashioned and inflexible 200 return, guarantee forming accuracy, improve yield rate.
