Description

Technical Field

[0001] This utility model belongs to the technical field of automatic adjustment centering devices, and specifically relates to a looper centering and correction device. Background Technology

[0002] Continuous production is crucial for galvanizing lines. Looping systems, which store strip steel, are essential for this process. A typical looping system holds 400-600 meters of strip steel, enough to sustain the galvanizing line for 4-6 minutes. However, the coordinated movement of the strip steel and the guide rollers inevitably leads to positional deviations. Existing looping alignment devices primarily correct deviations near the looping exit, which is insufficient to prevent strip snagging, curling, or even breakage during the strip's movement within the loop. Therefore, existing systems pose certain production risks and hidden dangers, requiring improvement and enhancement. Summary of the Invention

The movable frame is connected to the piston rod of the hydraulic cylinder and moves in a direction perpendicular to the movement of the strip under its drive.

[0006] Furthermore, one or both sides of the movable frame are fixed to the end of the piston rod of the hydraulic cylinder via connecting rods.

[0017] 2. This utility model uses a double-roller correction device at the looper inlet and outlet, and the width of the movable frame can be selected according to the horizontal distance between it and the steering roller, making it convenient to use.

An alignment detection frame 4 is located above the discharge side of the double-roller correction device 2 and the single-roller correction device 3. The alignment detection frame 4 is arranged perpendicular to the movement direction of the strip 1 and has a space in the middle for the strip 1 to pass through. A sensor for detecting the position of the strip is installed inside the alignment detection frame 4. The sensor controls the piston rod of the hydraulic cylinder 6 of the corresponding double-roller correction device 2 or single-roller correction device 3 to extend and retract, thereby correcting the strip 1.

[0028] like Figure 2As shown, the double-roller correction device 2 includes two first correction rollers 201 fixedly mounted on a movable frame 202.

One or both sides of the movable frame 202 are fixedly mounted to the end of the piston rod of the hydraulic cylinder 6 via connecting rods. The bottom of the movable frame 202 has 3-6 rows of evenly distributed first rollers 203. The first rollers 203 are mounted on matching first tracks 204, which are fixedly mounted on the top surface of a first fixed base 205, which is fixed to the ground. Two stops 7 are provided at the front and rear ends of the top surface of the first fixed base 205 to prevent the movable frame 202 from accidentally derailing.

[0029] like Figure 3 As shown, the single-roller correction device 3 includes a second correction roller 301 fixedly mounted on a movable seat 302.
