Beschreibung
Zusammenfassung:	The invention discloses a spiral supplying device for a powdery hazardous chemical substance packaging machine. The spiral supplying device comprises a feeding box, a discharging box and a spiral conveying assembly; powdery hazardous chemical substances are put into the feeding box, and the powdery hazardous chemical substances located in a feeding containing cavity are conveyed into a dischargingcontaining cavity through two spiral conveying mechanisms; and the conveying flow of one of the spiral conveying mechanisms is larger than that of the other spiral conveying mechanism, the powdery hazardous chemical substances are subjected to supplying conveying quickly through the spiral conveying mechanism with the larger conveying flow, thus the weight of the conveyed powdery hazardous chemical substances is close to the weight of quantitative supplying, then the accurate weight of powdery hazardous chemical substances are subjected to supplying conveying through the spiral conveying mechanism with the smaller co
