The spring enters the blanking groove 612 through the feed port 611 at the top of the blanking piece 61. The movable rod of the baffle cylinder 619 is pushed forward to make the baffle 614 block the discharge port 615. The movable rod of the block cylinder 618 drives the block 613 to retract. When the spring contacts the baffle 614, the block cylinder 618 pushes the block 613 forward to resist the penultimate spring, and the baffle cylinder 619 drives the baffle 614 to retract and open.The spring at the bottom falls into the spring receiving groove 711 on the grinding disc 71 through the discharge port 615 under the action of gravity, the baffle 614 is closed, the stop block 613 is retracted, the positioning block 642 is raised by the positioning cylinder 641, and the grinding disc 71 rotates.
