Raw material screening device for roller production

Abstract

The invention discloses a raw material screening device for roller production. According to the device, cast iron raw materials are placed in a storage hopper; a motor I is started to drive a conveyorbelt and a baffle to rotate; the baffle brings the raw materials in the storage hopper to a high position; a motor II is started to drive a gear I to rotate; the gear I is meshed with a half gear todrive the half gear to rotate; the half gear drives a transmission shaft to rotate; the transmission shaft drives a discharging groove to rotate, so that the discharging groove reaches the upper portion of an outer cylinder; by driving the discharging groove to rotate, in the working process of the outer cylinder, the discharging groove and the outer cylinder cannot make contact with each other, so that equipment can run more smoothly and cannot be damaged while the outer cylinder can be filled with materials conveniently; the motor is started to drive a rotating disc to rotate so as to drivethe outer cylinder to rotate, and each outer cylinder is filled with the materials; and after the filling is completed, the discharging groove is withdrawn. According to the invention, manual conveying of raw materials is avoided, only one outer cylinder is used for impurity removal, and the working efficiency is low.

Description

technical field [0001] The invention relates to the technical field of raw material screening, in particular to a raw material screening device for roll production. Background technique [0002] The main working parts and tools on the rolling mill that cause continuous plastic deformation of metals. The roll is mainly composed of three parts: roll body, roll neck and shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing, and the rolling force is transmitted to the stand through the bearing seat and the pressing device. The shaft head of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotational torque of the motor to the roll. The rolls can be arranged in the form of two rolls, three rolls, four rolls or multiple rolls in the rolling mill stand. [0003] Commonly used roll mater...

AI Technical Summary

Problems solved by technology

[0003] Commonly used roll materials include alloy forged steel, alloy cast steel and cast iron, etc.; in the process of selecting roll materials, it is necessary to select raw materials with the same particle size, so as to improve the quality of rolls; the existing equipment is manually transporting raw materials and only Impurities are removed through an outer cylinder, resulting in low work efficiency, and it is not convenient to remove impurities from raw materials, improve the quality of rolls, and it is not convenient to sieve raw materials into various types
