Steel ball classified feeding device

Abstract

The invention discloses a steel ball classified feeding device which comprises a rack, a steel ball feeding passage, a delivery mechanism, a screening passage and a driving mechanism, wherein the two ends of the delivery mechanism are communicated with the steel ball feeding passage and the screening passage respectively; the delivery mechanism includes a plurality of parallelly arranged carrier rollers; chain wheels are mounted on the two sides of each carrier roller and the carrier rollers are connected through a transmission chain; the driving mechanism drives the delivery mechanism to deliver steel balls on the delivery mechanism; the intervals of the carrier rollers of the delivery mechanism gradually increase to the lower limit value of the diameter of the standard steel ball from the end close to the steel ball feeding passage to the end close to the screening passage; the screening passage includes a main passage formed by a plurality of sequentially communicated pipelines with different diameters; the diameters of the pipelines decrease in sequence from the end close to the delivery mechanism to the end far from the delivery mechanism and the diameter of the pipeline farthest from the delivery mechanism is equal to the upper limit value of the diameter of the standard steel ball; the end of each pipeline, far from the delivery mechanism is communicated with a branch passage with the diameter equal to the diameter of the pipeline.

Description

technical field [0001] The invention relates to the technical field of steel ball detection equipment, in particular to a steel ball sorting and feeding device. Background technique [0002] Ball mill is one of the high-fine grinding machines widely used in industrial production. The steel ball of the ball mill is the grinding material medium of the ball mill equipment. The grinding effect is produced through the collision and friction between the steel balls of the ball mill and between the steel ball and the material. It is an important basic component, especially the precision industrial steel ball plays an important role in the development of the national economy. has a huge effect. Before the steel ball leaves the factory, in order to ensure the quality of the steel ball, it is usually necessary to carry out quality inspection on the steel ball. In the inspection work, the detection of the size of the steel ball is an important task. In the prior art, the size of the s...

Problems solved by technology

Before the steel ball leaves the factory, in order to ensure the quality of the steel ball, it is usually necessary to carry out quality inspection on the steel ball. In the inspection work, the detection of the size of the steel ball is an important task. In the prior art, the size of the steel ball is often manually inspected visually Or random inspection, not only requires the inspector to have high professionalism, but also requires the inspector to be highly focused, which can easily cause fatigue and labor intensity, and needs to be improved.
