Description

Technical Field

[0001] The utility model relates to the technical field of steel ball screening, in particular to a quality screening device for steel ball production. Background Art

[0002] During the production process, steel balls are typically sized based on their diameter. Diameter accuracy and surface quality are crucial quality criteria. Therefore, strict process control is required to ensure that these standards are met. Steel balls are sized and sorted based on diameter to meet specific application requirements in various fields and applications.

[0003] The Chinese utility model patent with announcement number CN218394551U discloses a screening device for producing bearing steel balls with a graded screening function, including a screening box. The screening box is provided with a plurality of inclined first, second, and third screen frames from top to bottom. The first, second, and third screen frames are respectively installed with a first screen, a second screen, and a third screen with successively increasing mesh diameters. A trapezoidal material receiving box is correspondingly provided below the first, second, and third screen frames. A material guide inclined plate installed on the inner wall of the screening box is provided between adjacent material receiving boxes. A pull-out assembly is installed between the material receiving box and the screening box. This utility model not only facilitates multi-stage synchronous screening of steel balls, thereby improving screening efficiency, but also effectively increases the contact time between the steel balls and the screen, thereby improving screening accuracy.

[0004] In the above technical solution, when screening the steel balls, the steel balls are directly placed in the first screen frame, the second screen frame and the third screen frame. Since the device itself lacks a mechanism to provide additional power to the steel balls, the steel balls themselves may be blocked in a certain screening frame. The blocked steel balls will reduce the screening efficiency. Therefore, a steel ball production quality screening device with a function of pushing steel balls to prevent blocking is designed to solve the above problem. Utility Model Content
