Stock bin processing device for packaging

The utility model relates to a stock bin processing device for packaging, which comprises a U-shaped plate, a stock bin, barium sulfate, a transmission assembly, a conveying assembly and a circulating assembly, the transmission assembly is arranged at the top of the inner side of the U-shaped plate, and the conveying assembly is arranged at the top of the U-shaped plate. The barium sulfate conveying device has the beneficial effects that when barium sulfate is poured into the stock bin to generate dust, the hopper in the conveying assembly is adjusted to a proper position by driving the transmission assembly, then the conveying assembly is driven to convey the raised barium sulfate into the circulating assembly, and then the circulating assembly is used for finally conveying the barium sulfate to the stock bin; pressure generated by a circulating pump in the conveying assembly is buffered through the circulating assembly, the situation that the pressure generated by the external circulating pump is directly c
