Description

Crescent roller skin correcting device

Technical Field

The utility model relates to a grinding device, in particular to a crescent roller skin correcting device.

Background

The roller press, also known as an extrusion mill and a roller mill, is novel energy-saving cement grinding equipment developed in the middle of the international 80 s, has a high-efficiency low-energy-consumption replacing ball mill pre-grinding system, and has the functions of reducing steel consumption and noise. The roller press comprises a frame, two roller systems, a transmission device, a torque bearing, a roller cover, a feeding device, a hydraulic (pressurizing) system, a main bearing lubricating system, a dry oil lubricating system, an electrical system and the like. The hydraulic (pressurizing) system acts on the non-supporting shaft surface of the roller press to drive the roller press to rotate, and the supporting shaft surface is easy to damage after long-time running, so that the roller press roller skin generates crescent deformation due to edge effect. According to previous experience, the roller press must be disassembled and returned to the factory for maintenance. The whole repair process has long construction period, high cost and poor economic benefit.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model aims to provide a crescent roller leather correction device, which enables a grinding wheel in a correction device to be tightly attached to the surface of a roller leather to grind and level the sharp angle at the crescent part through the tension force of a spring, thereby correcting the crescent deformation of a product.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a crescent roller skin correcting device comprises a roller cover and a roller skin, wherein the roller skin is arranged in the roller cover; the device also comprises a correcting device, a spring and a hanging lug; the hangers comprise a first hanger and a second hanger; the first hanging lug and the second hanging lug are arranged on the inner side surface of the lower end of the roller cover; the correction device is connected with the first hanging lug; one end of the spring is connected with the second hanging lug, and the other end of the spring is connected with the correcting device.

Further, the correcting device is symmetrically arranged on two inner sides of the lower end of the roller cover.

Further, the correcting device comprises a grinding wheel and a connecting device; the spring is connected with the connecting device.
