The two discharge ports 13 can also discharge steel balls. The baffle 12 is to prevent the steel balls from deviating. The angle of the feeding plate 9 can be adjusted, specifically through the threaded rods 6 at both ends of the front side of the feeding plate 9. The height of the front side of the feeding plate 9 can be adjusted up and down on the threaded rods 6. The rear side of the feeding plate 9 is fixed on the operating table 1. The tilt height of the front and rear sides of the feeding plate 9 is mainly adjusted by the threaded rods 6 on the front side.

[0022] The top of the operating platform 1 is equipped with fixed frames 17 on both the left and right sides behind the loading plate 9. Each fixed frame 17 is connected to the operating platform 1 by multiple fixed frame mounting bolts 18. Each fixed frame 17 has a vertical pole 22, and each vertical pole 22 is connected to its corresponding fixed frame 17 by multiple vertical pole mounting bolts 19. Each vertical pole 22 has a support frame 23 installed on its upper rear side. Each support frame 23 has a horizontal support frame 24. A pneumatic cylinder 26 is installed in the middle of the horizontal support frame 24.

The height of the feeding plate 9 can be adjusted on the operating table 1.

[0026] In this invention, steel balls are fed through a feeding plate 9. The steel balls are separated by a baffle 12 during feeding, allowing them to exit from both sides of the baffle 12, i.e., the two discharge slots 11. Two discharge ports 13 also discharge steel balls. The baffle 12 prevents the steel balls from shifting. The feeding plate 9 can be angled, specifically through the threaded rods 6 at both ends of the front side of the feeding plate 9. The height of the front end of the feeding plate 9 can be adjusted up and down on the threaded rods 6. The rear side of the feeding plate 9 is fixed to the operating table 1. The tilt height of the front and rear sides of the feeding plate 9 is mainly adjusted by the threaded rods 6 on the front side. Thus, the steel ball feeding mechanism for the centerless grinder can be tilted, improving feeding efficiency.

[0027] The left and right positions can be adjusted by the pneumatic cylinder 28, connecting frame 29, belt chain 30 and clamping member 31 on the movable shaft frame 27. The pneumatic cylinder 28 can adjust the height of the connected connecting frame 29 and clamping member 31. The pneumatic cylinder 28 lowers the clamping member 31 so that the upper surface of the operating table 1 is in the position of the two feeding slots 11, so that the feeding mechanism of the steel ball used for the centerless grinder can also clamp and fix the steel ball.
