AI Technical Summary

Technical Problem

In existing steel strip pretreatment devices, the spacing of the steel brushes is fixed, which cannot adapt to steel strips of different thicknesses and materials, resulting in uneven cleaning or excessive wear, affecting production efficiency and quality.

Method used

The telescopic assembly, which combines hydraulic rods and springs, dynamically adjusts the contact force between the steel brush and the steel strip surface, and enables quick replacement of the processing rollers through a detachable roller brush assembly.

Benefits of technology

This achieves uniformity and efficiency in steel strip surface pretreatment, reduces equipment downtime for adjustment and maintenance costs, and improves the efficiency of continuous production operations.

Abstract

This utility model relates to the field of steel strip pickling, and discloses a surface pretreatment device for steel strip before pickling. The device includes a housing, with cover plates fixedly connected to both sides of the housing. Each cover plate has a fixed ring fixedly connected inside, and a steel strip is slidably connected inside the fixed ring. Multiple fixed blocks are slidably connected inside the housing. Each fixed block has a telescopic component at its bottom or top, and a connecting block at its bottom or top. A roller brush assembly is provided between every two connecting blocks. Each telescopic component includes a hydraulic rod and a spring. In this utility model, the hydraulic rod is first activated according to the thickness of the steel strip to achieve a state of contact between the steel brush and the surface of the steel strip. This allows for adjustment of the distance between the steel brushes, avoiding the problem of issues arising during pretreatment caused by uniformly spaced steel brushes, thereby improving the efficiency of the surface pretreatment device for steel strip before pickling.
