Feeding device for valve pocket packaging machine

The utility model relates to a feeding device of a material quantitative packaging machine, in particular to a feeding device of a valve bag packaging machine. The technical solution is: between the adapter and the auger bearing, one end of the adapter is fixed on the side wall of the auger room, and the other end is fixed on the auger bearing seat, and the adapter is arranged between the auger shaft and the auger shaft. With end caps and dynamic seals, the auger chamber is closed, the auger shaft extends into the auger chamber, the auger bearing seat is separated from the auger chamber, and a cantilever shaft is formed outside the auger. With the utility model, since the adapter is added, the auger bearing seat is separated from the auger room, which fundamentally solves the problem that the material in the auger indoor enters the auger bearing seat. At the same time, the auger chamber and ventilation shaft hole of the stair section are designed to increase the conveying capacity of the auger without affecting the measurement accuracy of the packaging. The utility model has the advantages of reasonable structure, safe and reliable work, high material conveying efficiency, convenience and practicality and the like.
