AI Technical Summary

Technical Problem

When the existing aluminum plate belt bending straightener cleaning device is shut down for inspection, the residual pressure in the nozzle leads to concentrated injection of cleaning liquid, which easily causes point-like alkali corrosion to the surface of the aluminum plate and affects the cleaning quality.

Method used

A cleaning device including a liquid storage tank and several injection units is designed. The injection unit is composed of a rotatable injection tube, a swing cylinder, a bearing seat and a sector-shaped nozzle. The injection tube is rotatable, and the angle between the axis of the sector-shaped nozzle and the aluminum plate can be adjusted to 90° to avoid concentrated injection of the cleaning liquid.

Benefits of technology

It effectively avoids the corrosion of the alkali liquid on the surface of the aluminum plate, improves the cleaning quality, meets the quality requirements of aluminum plate production, and simplifies the structure and operation of the device.

Abstract

The utility model relates to a cleaning device, in particular to a cleaning device for an aluminum plate and strip stretch-bending straightener, and aims to solve the problem that the production quality cannot be met due to the fact that the surface of an aluminum plate is easily corroded by alkali liquor when the aluminum plate is cleaned in the prior art. The aluminum plate cleaning device is simple in structure and convenient to operate, the fan-shaped nozzles on the upper surface and the lower surface of the aluminum plate spray cleaning liquid to clean the aluminum plate in the cleaning process of the aluminum plate, the oscillating cylinder drives the rotatable spraying pipe to rotate during shutdown inspection, the included angles between the axes of the fan-shaped nozzles on the upper surface and the lower surface of the aluminum plate and the aluminum plate are 90 degrees, and the aluminum plate can be cleaned conveniently. And spraying holes of the fan-shaped nozzles all deviate from the upper surface and the lower surface of the aluminum plate, so that the cleaning liquid is prevented from being intensively sprayed to a certain area of the aluminum plate, and the technical problem of alkali liquor corrosion in the cleaning process of the aluminum plate is solved. The utility model belongs to the technical field of aluminum plate strip cleaning.
