Description

Technical Field

[0001] This utility model relates to a detection device for uncoiling and inspecting the surface quality of strip steel from a reversible rolling mill, belonging to the technical field of strip steel quality inspection equipment. Background Technology

[0002] As reversible rolling mills increasingly produce high-end food-grade tinplate, the quality requirements for these products are becoming increasingly stringent. Surface defects in the strip steel can lead to product downgrading, therefore, timely detection and resolution of surface defects are crucial. Currently, the strip steel production process on reversible rolling mills lacks a dedicated inspection platform for uncoiling and inspecting the strip's surface quality. Inspection requires workers to manually uncoil the strip and place it on the ground for examination. This primitive method not only poses safety risks but is also inconvenient, resulting in unsatisfactory inspection results. Furthermore, the portion of strip placed on the ground represents waste. Therefore, designing an inspection platform capable of uncoiling and simultaneously inspecting the surface quality of strip steel from reversible rolling mills is essential. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for uncoiling and inspecting the surface quality of strip steel in a reversible rolling mill. This device can easily uncoil the strip steel coil, enabling inspectors to safely, effectively, and systematically check the surface quality of the strip steel, so that staff can adjust the production process in a timely manner and improve the pass rate and yield of the strip steel.

[0004] The technical solution to the above technical problem is:

[0005] A device for uncoiling and inspecting the surface quality of strip steel from a reversible rolling mill includes a roller support, rollers, a drive motor, a reducer, and an inspection platform. The roller support consists of two parallel supports. Multiple rollers are mounted parallel to each other on the two sides of the roller support, with the rollers perpendicular to the length direction of the roller support. The strip coil is placed above the multiple rollers. The drive motor and reducer are fixed on one side of the roller support and connected to the reducer. The output shaft of the reducer is connected to the rollers via gears. The inspection platform is placed in front of the roller support, and the head of the strip coil is placed on the inspection platform.

[0006] The aforementioned device for uncoiling and inspecting the surface quality of strip steel in a reversible rolling mill comprises two rectangular frames on each side of the idler roller support. The upper middle part of the two side supports is arc-shaped, matching the outer circumference arc of the strip steel coil. Multiple bearing seats are fixed to the upper ends of the two side supports, and the two ends of multiple idler rollers are respectively connected to the bearing sets in the bearing seats. A motor mounting base plate is fixedly connected to the rear of one side support of the idler roller support. The drive motor and reducer are fixed on the motor mounting base plate. An output gear is installed on the output shaft of the reducer. A drive gear is fitted on one end of one idler roller, and the output gear of the reducer meshes with the drive gear of the idler roller.

[0007] The device for uncoiling and inspecting the surface quality of strip steel in the above-mentioned reversible rolling mill, wherein the inspection platform consists of a table and support legs, the table is a rectangular plane, and support legs are fixed at the four corners of the table, with the lower ends of the support legs placed on the ground.

[0008] The beneficial effects of this utility model are:

[0009] This utility model has multiple idlers installed on the idler bracket. The strip coil is placed on the idlers, which are driven to rotate by a drive motor and a reducer. The strip coil is driven to rotate by the idlers. When the strip coil rotates, the head of the strip coil can be unfolded. The inspection platform is placed in front of the strip coil. After the strip coil is unfolded, it is laid on the surface of the inspection platform for easy inspection by the inspectors. After the inspection is completed, the drive motor reverses to roll up the strip coil and retract it, thus completing the inspection of the surface quality of the strip.

[0010] This utility model has a simple structure and is easy to use. It can quickly unwind steel coils, standardize the quality inspection of steel strips, promptly detect and resolve quality problems, reduce the number of surface defects, improve the overall product qualification rate and yield, and ensure the safety of inspection personnel.
