Beschreibung
Zusammenfassung:	The invention discloses a continuous feeding device and a control method. A first storage mechanism and a second storage mechanism in the continuous feeding device are connected in the vertical direction. The vacuum extraction mechanism is connected to the upper portion of the first storage mechanism through a first pipeline, and the upper portion of the second storage mechanism communicates with the first pipeline through a second pipeline. The gas storage mechanism is connected to the second pipeline through a third pipeline; and the gas storage mechanism is transversely connected to the process cavity through a fourth pipeline via the bottom output end of the second material storage mechanism. Powder is injected into the first material storage mechanism, the first material storage mechanism and the second material storage mechanism are vacuumized through the vacuum extraction mechanism, then the air pressure is adjusted to atmospheric pressure through the air storage mechanism, the powder is conveyed to th
