AI Technical Summary

Technical Problem

In the existing bearing steel ball production process, the screening device is prone to steel ball accumulation and blockage, resulting in low screening efficiency, difficulty in achieving efficient three-stage separation of steel balls of different diameters, and poor sorting quality.

Method used

The drive motor drives the rotating rod and the stirring plate on it to rotate and stir above the screening plate. Combined with the double-layer inclined screening plate design, it prevents steel balls from accumulating. The discharge channel is controlled by the rotating sealing frame, realizing automatic counting and quantitative feeding of steel balls.

Benefits of technology

It significantly improves screening efficiency and continuity, realizes automatic and efficient three-stage separation of bearing steel balls, improves sorting quality and production efficiency, and achieves accurate counting and quantitative conveying of steel balls.

Abstract

This utility model discloses a counting and feeding device for the production and processing of bearing steel balls, relating to the field of bearing steel ball processing technology. The utility model includes a separation cylinder with two feed pipes fixedly installed at the top and communicating with its interior. A screening assembly is installed inside the separation cylinder, comprising a first screening plate and a second screening plate. The first screening plate has a first screening hole on its surface, and the second screening plate has a second screening hole on its surface. The diameter of the first screening hole is larger than the diameter of the second screening hole. This utility model uses a drive motor to rotate a rotating rod and its agitator plate above the screening plates, forcibly dispersing and propelling the bearing steel balls, effectively preventing the steel balls from accumulating and clogging above the screening holes, significantly improving screening efficiency and continuity. The double-layer inclined screening plate design, combined with agitation, achieves automatic and efficient three-stage separation of bearing steel balls according to diameter, improving sorting quality and production efficiency.
