Abstract
The utility model provides a molding powder classifier which comprises an air blowing mechanism. The air blowing mechanism is provided with a feed port and a discharge port, wherein the feed port is communicated with a molding powder conveying device, and the discharge port is communicated with a molding powder storing device. The air flows from the feed port to the discharge port through the air blowing mechanism to drive molding powder to be transferred from the molding powder conveying device to the molding powder storing device along with the air. The discharge port comprises a first outlet and a second outlet, wherein the first outlet is located in the top of the air blowing mechanism, the extending direction of the first outlet is consistent with the direction of the feed port, the second outlet is located in the bottom of the air blowing mechanism, and the extending direction of the second outlet is perpendicular to the direction of the feed port. According to the different particle diameters and different weights of the molding powder flowing in the air blowing mechanism, the molding powder located in an upper layer is discharged from the first outlet, the molding powder located in a lower layer is discharged from the second outlet, and the purpose of classifying the molding powder is achieved. According to the molding powder classifier, a spiral diversion groove is formed inside the air blowing mechanism and is used for guiding the flowing direction of the air and the molding powder, and classifying efficiency, working efficiency and product quality can be improved.
