For illustrative purposes.
For example, with reference to Fig. 1, Fig. 1 is a kind of structural schematic diagram of increasing material manufacturing power spreading device, including powdering platform 100, sets
Powder feeder unit 200 above the powdering platform 100 is set, is arranged above the powdering platform 100 and can be along the paving
The table top 110 of powder platform 100 divides powder device 300 toward polyslip, further includes the first limited block 400 (referring to Fig. 5), the second limit
Block 410 and scraper device 500, first limited block 400 and second limited block 410 are arranged in the powdering platform 100
Top along the two sides for dividing 300 glide direction of powder device, the scraper device 500, which is arranged, divides powder device 300 described
Lower section.Powdering platform 100 includes shaping substrate 120, position, that is, powdering platform 100 forming area where shaping substrate 120
130.Powder feeder unit 200 is provided with dusty material 600, divides powder device 300 that can accept the powder material in powder feeder unit 200
Material 600 divides powder device 300 such as left along visual angle shown in FIG. 1 along the table top 110 of powdering platform 100 toward polyslip
Right sliding.And divide powder device 300 that can hit the first limited block 400 and the second limited block 410 respectively.Wherein, powder feeder unit 200
Quantitatively supplying powder device can be used, such as can be quantitative for roller quantitatively supplying powder device, impeller quantitatively supplying powder device, fan-shaped swing
Powder feeder unit etc..
In conjunction with Fig. 2, above-mentioned divides powder device 300 to include that powder part 310, collision block 320 and elastic recovery part is divided (not to show in figure
Out).Wherein, divide powder part 310 to rotate relative to the powdering platform 100 to be arranged, the rotation axis for dividing powder part 310 is substantially parallel
It is described to be divided to powder part 310 that accept the powder feeder unit respectively including at least two in the table top 110 of the powdering platform 100
The pilot trench body 311 of 200 dusty materials 600 provided, and with the rotation for dividing powder part 310, two 311 energy of pilot trench body
It is enough to topple over towards two sides, the dusty material 600 of different pilot trench bodies 311 is discharged to 500 two sides of scraper device respectively.Collision block
320 be fixedly connected on it is described divide powder part 310, and collision block 320 can respectively with first limited block 400 and second limit
Block 410 is hit, to drive the pilot trench body 311 that can topple over towards two sides.Elastic recovery part described divides powder part 310 for driving
