[0002] Steel mills cut steel plates into rectangular sheets according to customer requirements. These rectangular sheets are mainly transported on the production line via conveyor rollers. Some processes require specific feeding directions for the steel sheets. If the steel sheets are fed at an angle, the processing quality may deteriorate, or even feeding may fail. Therefore, a centering device is needed to center the steel sheets and ensure that the feeding direction of the rectangular sheets meets the equipment requirements. Utility Model Content

[0015] See Figure 1-5 This embodiment describes an online centering device for rectangular steel plates, comprising a conveyor roller conveyor 2. Below the conveyor roller conveyor 2 are a centering mechanism 3 and a material-stopping mechanism 5. The centering mechanism 3 includes two guide support rods 31 arranged parallel to the roller shaft. A fixed beam 39, a movable beam A32, and a movable beam B33 are mounted on the two guide support rods 31. At least two pusher columns 34 are located at the top of the movable beams A32 and B33 at the roller gap, extending upwards through the conveyor roller conveyor 2. The fixed beam 39 is located between the movable beams A32 and B33, and a vertically arranged rotating shaft is fixed to the fixed beam 39, located on the center line of the conveyor roller conveyor 2. A connecting plate 35 is mounted on the rotating shaft. The center of the connecting plate 35 is rotatably connected to the rotating shaft. Connecting rods A37 and B38 of equal length are mounted on both ends of the connecting plate 35. One end of connecting rod A37 is rotatably connected to the end of the connecting plate 35, and the other end is rotatably connected to the movable beam A32. One end of connecting rod B38 is rotatably connected to the end of the connecting plate 35, and the other end is rotatably connected to the movable beam B33. The rotating shaft is connected to a drive motor 36. When the drive motor 36 drives the operation, connecting rods A37 and B38 always remain parallel. The material blocking mechanism 5 includes a hydraulic cylinder 52. The piston rod end of the hydraulic cylinder 52 is equipped with a retaining wheel 51, which is located in the roller gap of the conveyor roller table 2.

[0016] Furthermore, it also includes a PLC controller and a sensor 6. The sensor 6 is set on the upper surface of the fixed beam 39 to detect the steel plate 4 passing through the conveyor roller 2. The PLC controller is also connected to the sensor 6, the hydraulic cylinder 52 and the drive motor 36.

[0017] Furthermore, the guide wheel 51 is positioned on the center line of the conveyor roller conveyor 2.

[0018] Furthermore, the retaining wheel 51 is covered with a rubber buffer pad. When the steel plate 4 impacts the retaining wheel 51, the buffer pad provides cushioning, reducing the impact kinetic energy on the hydraulic cylinder 52, thereby enabling it to adapt to the faster conveyor roller 2.

[0019] This invention is typically installed at the feed inlet of equipment 1. The conveyor roller 2 is aligned with the feed inlet and its width is greater than the feed inlet. In the ready state, movable beams A32 and B33 are in a state away from the center line, and the hydraulic cylinder 52 is in the extended state. At this time, the height of the guide roller 51 exceeds the conveying plane of the conveyor roller 2. When a steel plate 4 comes onto the conveyor roller 2, it is first blocked by the guide roller 51. At the same time, the sensor 6 detects the steel plate 4 and sends a signal to the PLC controller. The PLC controller automatically controls the drive motor 36 to operate. The drive motor 36 drives the connecting plate 35 to rotate, which in turn drives the connecting rods A37 and B38. The connecting rod A37 drives the movable beam A32 to translate towards the center, and the connecting rod B38 drives the movable beam B33 to move towards the center. Since connecting rods A37 and B38 are of equal length and the rotating shaft is in the center position, movable beams A32 and B33 move the same distance towards the center simultaneously. The pusher columns 34 on movable beams A32 and B33 push the rectangular steel plate 4 from both sides towards the center line at the same time, thereby adjusting the posture of the rectangular steel plate 4 so that the center line of the steel plate 4 coincides with the center line of the conveyor roller 2. Then, the PLC controller controls the drive motor 36 to reverse the action to reset movable beams A32 and B33, and at the same time controls the hydraulic cylinder 52 to retract, so that the guide roller 51 descends below the plane of the conveyor roller 2. Finally, the conveyor roller 2 sends the adjusted steel plate 4 into the feed port of the equipment 1. When the steel plate 4 is completely removed, the hydraulic cylinder 52 extends again to put the guide roller 51 into the ready state.
