Dry pressing powder quantitative output mechanism for feeding machine

The utility model discloses a dry pressing powder quantitative output mechanism for a feeding machine, which comprises a feeding cylinder with a built-in feeding screw rod, a powder storage barrel for storing powder and a powder output assembly, and the tail end of the feeding cylinder is provided with the powder output assembly which is connected through an atomizing pump and is provided with an atomizing nozzle. A water source needing to be used for granulation is extracted through the spraying pump and sprayed to the powder output by the output port through the spraying opening, spraying and dust falling are carried out on powder flying due to material falling, and the probability that the powder is wasted due to flying caused by air fluctuation when the pressed powder is quantitatively output is reduced; further, the purposes of accurately proportioning the powder and the water source and improving the granulation effect are achieved; the fixed frame is provided with the folding guide cylinder arranged on
