In some embodiments, the distance between adjacent adjusting drive members 3 can be shortened to improve the refinement of the powder thickness adjustment, that is, the number of the adjusting drive members 3 is increased to shorten the distance between adjacent adjusting drive members 3, thereby dividing the entire gate plate 1 into more smaller partitions, and refining the adjustment of the gate plate 1 by the adjusting drive members 3.

In some embodiments, the lifting motors 31 are distributed at equal intervals. Preferably, the gate plate 1 is driven to rise and fall simultaneously by a plurality of the lifting motors 31, so that the gate plate 1 is lifted and lowered as a whole, thereby adjusting the gate plate 1 as a whole and the position of the gate plate 1. The spacing of the paving platforms 2 drives the gate plate 1 to block the powder that exceeds the spacing on the paving platform 2, so that powder of a preset thickness is formed on the paving platform 2, and one or more lifting motors 31 corresponding to the area with uneven powder thickness can drive a partial area of ​​the gate plate 1 to move up and down, so that a partial area of ​​the gate plate 1 is deformed, and the spacing between the partial area of ​​the gate plate 1 and the paving platform 2 is adjusted, thereby driving the powder thickness corresponding to the partial area to change accordingly, thereby realizing fine adjustment of the powder thickness on the paving platform 2, reducing the uneven thickness of the powder on the paving platform 2, and meeting the requirements of the rolling process.

In some embodiments, the deformation is controllable deformation, that is, elastic deformation. In some embodiments, the gate plate 1 is made of an elastic material. The elastic material can be one or more of elastic rubber, plastic, and fiber, so that a partial area of ​​the gate plate 1 can be elastically deformed under the drive of the adjusting drive member 3, thereby preventing the adjusting drive member 3 from tearing the gate plate 1, and at the same time effectively driving the gate plate 1 close to the side of the paving platform 2 to be parallel to the paving platform 2, thereby reducing the uneven thickness of the powder on the paving platform 2. Preferably, when spreading the material, the gate plate 1 is first driven as a whole by the adjusting drive member 3 to adjust the distance between the gate plate 1 and the paving platform 2, and then the gate plate 1 and / or the paving platform 2 perform a translational movement, and the gate plate 1 is used to block the powder material that exceeds the distance on the paving platform 2, so that powder material of a preset thickness is formed on the paving platform 2, and continuous paving is achieved on the paving platform 2.
