Description

Technical Field

[0001] This invention relates to the field of conveying and guiding technology, specifically to a hot-rolled steel plate conveying and guiding mechanism. Background Technology

[0002] Hot-rolled steel sheets need to be conveyed during processing, typically using roller conveyors. To prevent the steel sheets from shifting during conveying, guiding mechanisms are usually installed on the conveyor.

[0003] For example, the published utility model patent CN212424525U discloses a steel plate conveying and guiding mechanism, which mainly includes at least two oppositely arranged guide wheels above the conveying rollers. The spacing between the guide wheels can be adjusted by a lead screw, and the guide wheels limit and guide the steel plate. Additionally, some mechanisms use partitions for guiding and limiting. These structures are more effective for conveying shorter plates, but may cause jamming during the conveying of longer plates. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hot-rolled steel plate conveying and guiding mechanism.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] The present invention provides a hot-rolled steel plate conveying and guiding mechanism, including a swing arm disposed on a roller conveyor. Two sets of swing arms are symmetrically arranged along the length of the roller conveyor. The middle part of the swing arm is rotatably connected to the conveyor. A driving mechanism is installed at the bottom of the swing arm. The driving mechanism drives the swing arm to swing on the conveying roller of the roller conveyor to adjust the conveying direction of the hot-rolled steel plate.

[0007] It also includes a guide wheel located in the middle of the roller conveyor. The guide wheel is driven by a motor to achieve forward and reverse rotation. The direction of the guide wheel's rotation axis is consistent with the conveying direction. The guide wheel is configured on a liftable base. When the guide wheel rises to its limit position, it can lift the steel plate on the conveying roller. When the guide wheel falls to its limit position, it can be hidden under the conveying roller.

[0008] As a preferred embodiment of the present invention, a rotating shaft is fixedly connected to the middle of the swing arm, and the rotating shaft is rotatably connected to the frame of the roller conveyor.

[0009] As a preferred embodiment of the present invention, the driving mechanism includes a cylinder, the base of which is hinged to the side wall of the frame of the roller conveyor. A first connecting rod and a second connecting rod at an angle to each other are fixedly installed at the bottom of the rotation shaft of one of the swing rods, and a third connecting rod is fixedly installed at the bottom of the rotation shaft of the other swing rod. The distal end of the first connecting rod is hinged to the output end of the cylinder. A fourth connecting rod is also provided, which is hinged between the second and third connecting rods. The direction of the fourth connecting rod is intersecting that of the cylinder.

[0010] As a preferred embodiment of the present invention, guide wheels are installed at both ends of the swing arm, and the guide wheels are rotatably connected to the swing arm, with the axis of rotation of the guide wheels being vertical.

[0011] As a preferred embodiment of the present invention, multiple sets of guide wheels are provided, with each set of guide wheels positioned at the center along the conveying direction.

[0012] The beneficial effects of this invention are:

[0013] The present invention is provided with two sets of guiding mechanisms, mainly a swing arm at the front end of the conveying direction and a guide wheel at the rear end. The swing arm adopts a rotating mechanism, which can guide and limit the front end of the steel plate on both sides. The guide wheel supports the rear end of the steel plate and causes the steel plate to move laterally by rotation, thereby adjusting the posture of the rear end of the steel plate and preventing it from getting stuck during the conveying process.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-3 As shown, it includes a swing arm 3 installed on a roller conveyor. Two sets of swing arms 3 are symmetrically arranged along the length of the roller conveyor. The middle part of the swing arm 3 is rotatably connected to the conveyor. A drive mechanism is installed at the bottom of the swing arm 3. The drive mechanism drives the swing arm 3 to swing on the conveying roller of the roller conveyor to adjust the conveying direction of the hot-rolled steel plate.

[0020] Reference Figure 2 as well as Figure 3 As shown, a rotating shaft 46 is fixedly connected to the middle of the swing arm 3. The rotating shaft 46 is rotatably connected to the frame of the roller conveyor. The drive mechanism includes a cylinder 41, the base of which is hinged to the side wall of the roller conveyor frame. A first connecting rod 47 and a second connecting rod 48 at an angle to each other are fixedly installed at the bottom of the rotating shaft 46 of one swing arm 3, and a third connecting rod 43 is fixedly installed at the bottom of the rotating shaft 46 of the other swing arm 3. The distal end of the first connecting rod 47 is hinged to the output end of the cylinder 41. A fourth connecting rod 42 is also provided, which is hinged between the second connecting rod 48 and the third connecting rod 43. The direction of the fourth connecting rod 42 intersects with that of the cylinder 41. This intersecting linkage structure enables the two swing arms 3 to move synchronously.

[0021] Guide wheels 31 are installed at both ends of the swing arm 3. The guide wheels 31 are rotatably connected to the swing arm 3, and the axis of rotation of the guide wheels 31 is in the vertical direction.

[0022] The system also includes guide rollers 2 located in the middle of the roller conveyor. Guide rollers 2 are driven by a motor to rotate in both directions. The axis of rotation of guide rollers 2 is aligned with the conveying direction. Guide rollers 2 are mounted on a liftable base. When guide rollers 2 rise to their limit position, they can lift the steel plate on the conveying rollers; when guide rollers 2 descend to their limit position, they can be hidden under the conveying rollers. Multiple sets of guide rollers 2 are provided, preferably two sets. Each set of guide rollers 2 is positioned in the middle along the conveying direction. Friction ridges are provided on the circumferential surface of guide rollers 2 to improve friction.

[0023] Application scenario of this application: Steel plate conveyor lines typically handle steel plates transported by robotic arms or output from uncoilers. During loading, the steel plates may deviate significantly. When the deviated steel plate is about to reach the position of the swing arm 3, the guide wheel 2 can adjust the steel plate according to its posture. During adjustment, the guide wheel 2 is first raised slightly to lift the steel plate, generally by 1-2 cm. Lifting it too far will cause wear between the steel plate and the conveyor rollers. Depending on the direction of the steel plate's deviation, the guide wheel 2 rotates forward or backward. Two sets of guide wheels 2 installed at intervals can work together, such as one guide wheel rotating forward and the other rotating backward, to control the posture of the steel plate. However, it is worth mentioning that the control of the guide wheels does not rotate the steel plate to a level posture all at once, but only to prevent the steel plate from deviating significantly when it enters the middle of the swing arm 3. Therefore, subsequent limiting and guiding mainly rely on the forced limiting of the two swing arms 3, with the guide wheel 2 playing an auxiliary role.

[0024] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
