Intelligent granule packaging machine

The invention discloses an intelligent granule packing machine. The machine comprises a rectangular shell for placing a plastic bag, the plastic bag is placed inside the rectangular shell, the plastic bag is adsorbed and expanded by negative pressure suction holes in the inner wall of the rectangular shell, granules enter a packing cavity through an upper opening of a packing box, the gravity of the granules pushes and drives the whole packing box to descend to stretch a spring, the purpose of putting the granules into the plastic bag after the packing box stretches into the plastic bag is achieved, packing devices on two sides of the packing box further expand an opening of the plastic bag, the situation that powder in the granules adheres to the opening of the plastic bag and is not prone to sealing is avoided, when the granules are blocked by check blocks on the inner wall of the packing cavity, the granules slowly move downwards, and powder impurities in the granules fall into a dust collection cavity fro
