The upper end of the guide plate 31 is fixedly connected to the discharge plate 4, and the lower end of the guide plate 31 gradually tilts towards the discharge end 8.

The side limiting wheels 32 are rotatably mounted on the slider, the slider is mounted on the slide rail, the slide rail is fixedly connected to the base 1, a lead screw pair is fixedly connected to the slider, the lead screw pair is mounted on the lead screw 33, the lead screw 33 is rotatably connected to the base 1, and a third rotating wheel 34 is fixedly connected to one end of the lead screw 33. An annular limiting groove 35 is provided on the circumferential surface of the side limiting wheel 32. By rotating the lead screw 33, the position of the side limiting wheel 32 is controlled, so that the side limiting wheel 32 can laterally limit the substrate of different widths, ensuring that the substrate can be accurately fed for powder spreading.

[0023] As a preferred embodiment of the above technical solution, the upper end of the feeding plate 4 is provided with movable openings 36 on both sides, the movable openings 36 are connected to the feeding channel 5, and an adjusting plate 37 is inserted into the movable opening 36.

The portions of the adjusting plate 37 inserted into the feeding channel 5 are located in the grooves on both sides. By pulling the adjusting plates 37, the distance between the two adjusting plates 37 is changed, thereby controlling the width of the powder falling.

[0024] The rotatable connection in this application is a traditional rotatable connection method, such as using bearings. The control method for rotating the first adjusting screw 12, the second adjusting screw, the third adjusting screw 20, the fifth adjusting screw 29, and the lead screw 33 to achieve positional movement can also employ existing methods for achieving linear displacement, such as cylinders or linear motors. Alternatively, an existing drive method can be used, such as replacing the rotating wheel with a motor to drive the aforementioned screws or lead screw 33 to rotate.

[0025] It is worth mentioning that the technical features of bearings, motors, cylinders, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent.
