The connecting rods 2 are multiple and evenly distributed along the circumference of the annular plate 1. The spacing between two adjacent connecting rods 2 is greater than the diameter of the head and tail balls. Since the head and tail balls are unqualified, the spacing between two adjacent connecting rods 2 is greater than the diameter of the head and tail balls, so that the unqualified head and tail balls can be directly screened out when the processed steel balls are conveyed.

[0031] refer to Figure 1-Figure 4, the support bottom plate 3, the screening assembly is rotatably connected to the support bottom plate 3 through the rotating member 4; the rotating member 4 includes a base 41 arranged on the support bottom plate 3, an embedded groove 42 arranged on the upper end surface of the base 41, and a rolling bearing 43 arranged in the embedded groove 42, the two ends of the embedded groove 42 extend to the side of the base along the length of the base 41, and the rotating member 4 is arranged on both sides of each annular plate 1, and part of the structure of the annular plate 1 is embedded in the embedded groove 42 and tangent to the outer edge surface of the rolling bearing 43. The rolling bearing 43 is connected to the embedded groove 42 by a bolt 44, and the inner ring of the rolling bearing 43 is fixed on the main body of the bolt 44, and the rolling bearing 43 can rotate around the main body of the bolt 44.

The axis of the feed pipe 51 and the axis of the annular plate 1 are located on the same straight line, and the screening assembly is driven to rotate by the drive assembly 5, thereby driving the steel balls entering the screening assembly to be transported from the feed end to the discharge end, and unqualified steel balls are screened out during the transportation process.

[0033] refer to Figure 1-Figure 4 The inner diameter of the annular plate 1 provided with the feed pipe 51 is smaller than the inner diameter of the other annular plate 1, and the diameter of the circle surrounded by the plurality of connecting rods 2 gradually increases from the feed end to the discharge end along the axis of the screening component. This structural setting facilitates the transportation of steel balls, and the steel balls are not easily stuck in this screening component, so the head and tail balls can be screened during the transportation process.

[0034] refer to Figure 2 A collecting frame 6 is provided on the supporting bottom plate 3 and below the screening component. The collecting frame 6 is used to collect the screened head and tail balls to facilitate subsequent processing of the head and tail balls.
