AI Technical Summary
In existing technologies, parts such as steel strips and steel plates are relatively heavy and require workers to lift them into the leveling machine for leveling. Furthermore, the steel plates need to be manually pushed into the leveling machine, which results in excessive physical exertion for workers and makes it impossible to level them quickly.
A lifting structure for loading a leveling machine was designed, including a shell, a horizontal plate, a rotating roller, a support frame, a drive plate driven by a servo motor, and an airbag system. The drive plate driven by the servo motor pushes the placement plate up to be level with the rotating roller. The expansion and contraction of the airbag realizes the automatic lifting and pushing of the steel plate, reducing the downward pressure of manually pushing the steel plate.
It enables automatic lifting and pushing of steel plates, reducing the labor consumption of workers and improving the efficiency and safety of the leveling process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of leveling machine technology, and in particular to a lifting structure for feeding materials into a leveling machine. Background Technology
[0002] The leveling of ultra-thin steel strips is generally carried out by a leveling machine. A leveling machine generally includes an upper roller group and a lower roller group. The upper roller group and the lower roller group work together to form a leveling gap, so as to achieve the rolling leveling of the steel strip.
[0003] Because steel strips, steel plates, and other parts are heavy, workers need to lift them into the leveling machine for leveling. At the same time, when the steel plate enters the leveling machine, because the steel plate is bent and uneven, workers also need to press the steel plate into the leveling machine by hand, which will cause excessive physical exertion for workers and is not suitable for the current rapid leveling of steel plates in the factory. Utility Model Content
[0004] The purpose of this utility model is to solve the following shortcomings in the prior art: because the steel strips, steel plates and other parts are heavy, workers need to lift them into the leveling machine for leveling. At the same time, when the steel plate enters the leveling machine, because the steel plate is bent and uneven, workers also need to push the steel plate into the leveling machine by hand, which will lead to excessive physical exertion for workers. It is not suitable for the current rapid leveling of steel plates in the factory. Therefore, a lifting structure for loading the leveling machine is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lifting structure for feeding a leveling machine includes a housing and two horizontal plates. Both horizontal plates are fixedly connected inside the housing, and multiple rotating rollers are rotatably connected between the two horizontal plates.
[0007] A support frame is fixedly connected between the two horizontal plates. A feeding component is installed on the support frame. The feeding component includes a drive plate, a vertical plate, square blocks, and support rods. The vertical plate is U-shaped. Through slots are opened on both sides of the vertical plate. The two square blocks are slidably connected in the through slots. The two support rods are fixedly connected to the square blocks. A placement plate is fixedly connected between the two support rods. One end of each of the two drive plates is hinged to both sides of the support frame. A sliding groove is opened at the end of the drive plate away from the support frame. The support rod is slidably connected in the sliding groove.
[0008] Preferably, a fixing plate is fixedly connected to one side of the support frame, and a servo motor is fixedly connected to the fixing plate, with the drive end of the servo motor fixedly connected to the drive plate.
[0009] Preferably, a U-shaped plate is fixedly connected to the outer shell, a mounting plate is slidably connected inside the U-shaped plate, and multiple rotating wheels are rotatably connected to the mounting plate.
[0010] Preferably, an airbag is fixedly connected to the mounting plate, and the end of the airbag away from the mounting plate is fixedly connected to the inner wall of the U-shaped plate. A spring is fixedly connected between the mounting plate and the inner wall of the U-shaped plate.
[0011] Preferably, a square box is fixedly connected to one end of the support frame, a piston plate is slidably connected inside the square box, and a connecting pipe is fixedly connected between the square box and the airbag.
[0012] Preferably, the piston plate is disposed on the underside of one of the drive plates.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The drive plate pushes the support rod and the square block to slide vertically upward in the through groove on the vertical plate. The placement plate moves vertically upward along with the square block on the vertical plate until it is flush with the rotating roller. At this point, the steel plate on the placement plate can be easily pushed onto multiple rotating rollers, making it easy to move into the outer casing for leveling.
[0015] The counterclockwise rotation of the drive plate can further compress the piston plate downwards. The downward movement of the piston plate compresses the gas in the square box, which flows through the connecting pipe into the air bladder. The air bladder expands due to the increased gas and pushes the mounting plate downwards. The rotating wheel moves down with the mounting plate until it contacts the upper surface of the steel plate, which can compress the steel plate. At this time, the worker only needs to apply a horizontal pushing force to move the steel plate to send it into the outer shell for leveling. The worker does not need to apply downward pressure to the steel plate while pushing it, thus reducing the worker's labor. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A lifting structure for feeding a leveling machine includes a housing 1 and a horizontal plate 10. The housing 1 is the housing of a leveling machine in the prior art. The leveling machine is prior art and will not be described in detail here. Both horizontal plates 10 are fixedly connected inside the housing 1. Multiple rotating rollers 4 are rotatably connected between the two horizontal plates 10. When a steel plate is placed on the rotating rollers 4, the steel plate is pushed to move horizontally on the rotating rollers 4, so that the steel plate can be transported into the leveling machine for leveling processing.
[0024] A support frame 16 is fixedly connected between two horizontal plates 10. A feeding component is installed on the support frame 16. The feeding component includes a drive plate 9, a vertical plate 5, square blocks 7, and support rods 8. The vertical plate 5 is U-shaped, and through slots are opened on both sides of the vertical plate 5. The two square blocks 7 are slidably connected in the through slots. The square blocks 7 can only move vertically up and down in the through slots. The two support rods 8 are fixedly connected to the square blocks 7. A placement plate 6 is fixedly connected between the two support rods 8. The placement plate 6 moves along with the support rods 8 in the through slots on the vertical plate 5. When the support rod 8 and the square block 7 are at the top of the through groove, the upper surface of the placement plate 6 is flush with the upper surface of the rotating roller 4. One end of each of the two drive plates 9 is hinged to both sides of the support frame 16. A sliding groove is opened at the end of the drive plate 9 away from the support frame 16. The support rod 8 is slidably connected in the sliding groove. The swing of the drive plate 9 can push the support rod 8 to move. A fixed plate 15 is fixedly connected to one side of the support frame 16. A servo motor 14 is fixedly connected to the fixed plate 15. The drive end of the servo motor 14 is fixedly connected to the drive plate 9.
[0025] A U-shaped plate 2 is fixedly connected to the outer shell 1. A mounting plate 3 is slidably connected inside the U-shaped plate 2. Multiple rotating wheels 19 are rotatably connected to the mounting plate 3. Part of the rotating wheels 19 protrudes outside the mounting plate 3. An airbag 17 is fixedly connected to the mounting plate 3. The end of the airbag 17 away from the mounting plate 3 is fixedly connected to the inner wall of the U-shaped plate 2. A spring 18 is fixedly connected between the mounting plate 3 and the inner wall of the U-shaped plate 2. The spring 18 always exerts an upward pulling force on the mounting plate 3. A square box 12 is fixedly connected to one end of the support frame 16. A piston plate 11 is slidably connected inside the square box 12. A connecting pipe 13 is fixedly connected between the square box 12 and the airbag 17. The piston plate 11 is located under one of the drive plates 9. When the drive plate 9 rotates clockwise, the angle changes and it will not squeeze the piston plate 11.
[0026] In this utility model, when in use, since the placement plate 6 is close to the ground, the steel plate is first placed on the placement plate 6, and then the servo motor 14 is driven. The drive shaft of the servo motor 14 rotates clockwise and drives one of the drive plates 9 to rotate clockwise with the hinge point with the support frame 16 as the fulcrum. The drive plate 9 pushes the support rod 7 and the square block 7 to slide vertically upward in the through groove on the vertical plate 5. The placement plate 6 moves vertically upward on the vertical plate 5 along with the square block 7 until it is flush with the rotating roller 4. At this time, the steel plate on the placement plate 6 can be easily pushed onto multiple rotating rollers 4, which makes it easy to move into the outer shell 1 for leveling.
[0027] Simultaneously, as the drive plate 9 rotates clockwise to push the placement plate 6 upward, it no longer squeezes the piston plate 11. At this time, the mounting plate 3 moves upward under the tension of the spring 18, and the gas in the airbag 17 is squeezed and flows back into the square box 12 through the connecting pipe 13, pushing the piston plate 11 upward. As the placement plate 6 moves to be flush with the rotating roller 4, the mounting plate 3 and the rotating wheel 19 move away from the rotating roller 4, which can push the steel plate onto multiple rotating rollers 4. When the drive servo motor 14 drives the shaft to rotate counterclockwise, it can drive the drive plate 9 to reset and rotate, and push the support rod 8 and the square block 7 downward and reset, so that the subsequent steel plates can be placed on the placement plate. The material continues to be fed onto plate 6, while the drive plate 9 rotates counterclockwise to squeeze the piston plate 11 downwards again. The downward movement of the piston plate 11 squeezes the gas in the square box 12 and flows through the connecting pipe 13 into the air bladder 17. The air bladder 17 expands due to the increase in gas and pushes the mounting plate 3 downwards. At the same time, the spring 18 is stretched. The rotating wheel 19 moves down with the mounting plate 3 to contact the upper surface of the steel plate, which can squeeze the steel plate. At this time, the worker only needs to apply a horizontal pushing force to move the steel plate to send it into the outer shell 1 for leveling. The worker does not need to apply downward pressure to the steel plate while pushing it, so as to reduce the labor of the workers.
[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
