Description

Technical Field

[0001] This utility model relates to the technical field of steel strip processing equipment, and in particular to a steel strip correction device for shot blasting machines. Background Technology

[0002] Shot blasting machines are casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Horizontal shot blasting machines are commonly used for rust removal and other treatments on steel strips. However, when a horizontal shot blasting machine impacts a steel strip from both sides horizontally, the impact is uneven due to gravity, affecting product quality. Therefore, the steel strip needs to be switched from a horizontal conveying state to a vertical orientation before entering the shot blasting chamber to ensure uniform impact from the high-speed shot on both sides. However, existing methods are prone to problems such as deviation, edge stress concentration, and deformation during the steel strip switching process, directly affecting shot blasting quality and subsequent processing accuracy, and even leading to steel strip breakage or equipment damage.

[0046] Example 2

[0047] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, a correction device for a steel strip 4 shot blasting machine includes a discharge platform 1 for outputting a horizontally placed steel strip 4, at least seven sets of turning rollers 2 arranged sequentially at the discharge end of the discharge platform 1 along the traveling direction of the steel strip 4, and a correction roller group 3.
