The invention relates to a sphere material roundness sorting
machine which comprises a base frame body, a storage hopper, a discharging trough, a conical sorting plate, a retention ring, a
drive motor, a rotary bearing, a shaft sleeve, a shaft sleeve installation plate, a waste
barrel and a finished product
barrel. The storage hopper, the discharging trough, the conical sorting plate and the wastebarrel are sequentially arranged on the base frame body from top to bottom; the conical sorting plate is in a
funnel shape; the rotary bearing is fixed under the conical sorting plate and is locatedoutside the waste
barrel; the shaft sleeve is arranged outside the rotary bearing in a sleeve mode and is fixed onto the shaft sleeve installation plate; the shaft sleeve installation plate is arranged on the base frame body; the
drive motor is arranged on the shaft sleeve installation plate and is connected with the rotary shaft; the finished product barrel is arranged in the waste barrel; a
discharge hole of the finished product barrel and an outlet of the waste barrel are not shared; and a notch groove is formed in the retention ring and is located on an opening of the upper edge of the finished product barrel. According to the sphere material roundness sorting
machine disclosed by the invention, the funnel-shaped conical sorting plate is arranged, so that the
sorting problem of the sphere material roundness can be effectively solved.
