AI Technical Summary

Technical Problem

The traditional air knife baffle has a complicated loading and unloading process, and it is impossible to avoid the main parts of the equipment during maintenance, making it difficult to meet the needs of high-speed operation and rapid maintenance of hot-dip galvanizing production lines.

Method used

An air knife baffle structure was designed, comprising a crossbeam, baffle, movable frame, connecting components, and drive adjustment components. The baffle's angle and spacing can be flexibly adjusted by components such as a fixed shaft, rotating block, telescopic cylinder, and adjusting screw, avoiding key positions of the equipment and facilitating maintenance and operation. The adjusting screw is protected from zinc liquid splashes by an accordion-style telescopic cover.

Benefits of technology

It improves loading and unloading efficiency, ensures zinc coating uniformity, simplifies the maintenance process, avoids equipment interference, and enhances the operating efficiency and maintenance convenience of the production line.

Abstract

This disclosure relates to the technical field of hot-dip galvanized sheet production. One embodiment of this disclosure provides an air knife baffle for hot-dip galvanized sheet production, comprising: a cross frame and a pair of baffles, both baffles being disposed at the bottom of the cross frame; a movable frame disposed inside the cross frame; a connecting assembly disposed between the cross frame and the baffles; and a drive adjustment assembly disposed between the movable frame and the cross frame. The connecting assembly includes a fixed shaft disposed on the outer end face of the movable frame, a rotating block mounted on the fixed shaft, a telescopic cylinder disposed on the lower end face of the rotating block, a fixed frame disposed at the output end of the telescopic cylinder, a first bolt mounted on the top of the insert frame, the first bolt being screwed into the fixed frame, and a reinforcing plate disposed on the surface of the movable frame. This technical solution solves the technical drawbacks of traditional air knife baffles in the prior art, such as cumbersome loading and unloading processes and the inability to avoid key equipment locations during maintenance, making it difficult to meet the requirements of high-speed operation and rapid maintenance in hot-dip galvanized production lines.
