Vibrating disc

The utility model relates to a vibrating disk which comprises a disk body, a spiral climbing ring is arranged on the inner wall of the disk body in the circumferential direction, a plurality of blanking grooves are formed along the climbing ring, and the difference between the diameter of the inner arc edge of each blanking groove and the outer diameter of the climbing ring at the position where the blanking grooves are formed is larger than the width of materials and smaller than the length of the materials. The material receiving part is connected and communicated with the outlet of the tray body; and the first linear vibrator is positioned below the material receiving part. According to the vibration disc, through the arrangement of the disc body matched with the climbing ring, the spiral climbing effect of materials can be well achieved, and a good condition is provided for follow-up powder screening; through the arrangement of the blanking groove and the different requirements of the diameter of the blan
