When the lifting platform 3 drives the powder bag 4 to move to the cross bar 721, since the cross knife 723 is aligned with the vertical knife 62, the top right end of the right-angle rod 722 enters the damaged powder bag 4 from the opening, and the second cylinder 724 is controlled to drive the cross bar 721 to move back and forth, so that the right-angle rod 722 strikes and vibrates the inside of the powder bag 4, thereby shaking off the remaining powder. While the right-angle rod 722 strikes the powder bag 4, the cross knife 723 will The left side of the powder bag 4 is cut open, so that the opening of the powder bag 4 is larger and the powder is dropped more cleanly. After the powder is dropped, the lifting platform 3 continues to drive the powder bag 4 to move to the collection box 742. At this time, the first cylinder 511 is controlled to make the first nail column 521 and the second nail column 522 slide on the loose claw groove 741, and make the inner sides of the first nail column 521 and the second nail column 522 detach from the damaged powder bag 4, so that the powder bag 4 falls into the collection box 742 and is collected.
