Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology, specifically a steel rolling mill that facilitates material feeding and prevents deviation. Background Technology

[0002] Steel rolling production refers to the process of taking steel billets (such as continuously cast billets, primary rolled billets, etc.) produced in the steelmaking process and applying external force to them through equipment such as rolling mills to cause plastic deformation, thereby obtaining steel products with certain shapes, sizes and properties. It is a crucial link in the steel production process, connecting steelmaking and deep processing of steel products, and transforming the primary products obtained from steelmaking into final steel products that meet the needs of different industries.

[0003] An existing patent (publication number: CN219766394U) discloses a rolling mill with convenient material unloading, including: a base and a push-pull mechanism. Two symmetrically arranged support frames are fixedly installed on the top side of the base. A first roll and a second roll are rotatably connected between the two support frames. Two rectangular frames are fixedly welded to the base, and each rectangular frame is rotatably connected to a support rod. A connecting plate is fixedly installed on the bottom side of the two support rods, and a second conveying roll is installed on the two support rods. The push-pull mechanism is located on the base. When the servo motor of this invention rotates, it drives the screw to rotate, thereby causing the moving rod to move within the rectangular frame under the cooperation of the slider and the slide groove. This causes the two push-pull rods to flip, pushing the connecting plate and the two support rods to flip, thus realizing the adjustment of different conveying heights. This facilitates docking with material conveying platforms of different heights, improves the applicability of the rolling mill, and facilitates material unloading.

[0004] During use, the above-mentioned device can adjust different conveying heights to facilitate docking with material conveying platforms of different heights, improve the applicability of the rolling mill, and facilitate material unloading. However, due to the sloping shape during the unloading process, the steel plate will deviate on the conveying rollers under the action of gravity. Furthermore, if the conveying speed of the steel plate is too fast, the steel plate will also jump on the conveying rollers, thereby affecting the conveying of the steel plate. Therefore, there is an urgent need for a rolling mill that is easy to unload and prevents deviation to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rolling mill that facilitates material feeding and prevents deviation, possessing advantages such as preventing deviation and ensuring stable material feeding, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rolling mill that facilitates material feeding and prevents deviation, comprising a machine body with two conveying paths at both ends, one of which is sloping and the other is horizontal. Both conveying paths are composed of multiple conveying rollers arranged side by side. A set of first adjusting plates are arranged on both sides of the sloping conveying path, and the first adjusting plates are parallel to the sloping conveying path. Several rotating columns are distributed along the length of the bottom of the two first adjusting plates, and all rotating columns are rotatably connected to the first adjusting plates. A rubber contact wheel is fixedly sleeved at the end of each rotating column. Each rotating column is fitted with a pressure block, which is located above the rubber contact wheel. All the pressure blocks have a conical structure that is larger at the top and smaller at the bottom. Two second adjusting plates are set on both sides of the horizontal conveying path on the machine body. Each second adjusting plate has a curved elastic metal plate fixed on its top. The two elastic metal plates are arranged facing each other. Multiple balls are installed in the recess of each elastic metal plate along its length.

[0007] Preferably, cylinders are installed on the inner wall of the machine body at positions corresponding to the two first adjusting plates, and the piston ends of the cylinders are fixedly connected to the corresponding first adjusting plates.

[0008] Preferably, the two second adjustment plates can move synchronously toward or away from each other along the width direction of the machine body.

[0009] Preferably, the horizontal section of the machine body has two rectangular slide rails fixed along its width direction, and the second adjusting plate is slidably guided on the two rectangular slide rails.

[0010] Preferably, threaded sleeves are fixedly connected to the bottom ends of the two second adjusting plates, and a rotating rod is rotatably installed on the horizontal section of the machine body. The rotating rod is distributed parallel to the conveying roller, and first threaded grooves are opened at both ends of the rotating rod. The rotation directions of the two first threaded grooves are kept opposite. The threaded sleeves at the bottom of the two second adjusting plates are respectively sleeved on the corresponding first threaded grooves. By driving the rotating rod to rotate, the two second adjusting plates move synchronously towards or away from each other.

[0011] Preferably, the pressure block can move along its axial direction relative to the rotating column to change the distance between the pressure block and the rubber contact wheel.

[0012] Preferably, a second threaded groove is provided on the circumferential surface of each rotating column, and all pressure blocks are threadedly sleeved on the corresponding second threaded groove.

[0013] Preferably, all the pressure blocks are made of rubber, and the conical surface of the pressure block has an arc transition.

[0014] Preferably, the conveyor rollers distributed along the sloping conveyor path are rotatably connected to the inner wall of the machine body via damping bearings.

[0015] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: (1) First adjusting plates are set on both sides of the inclined conveying path. Rubber contact wheels are fixed at the ends of the rotating columns at the bottom of the plates. When the steel plates move, the rubber contact wheels contact the sides of the steel plates, which can guide the steel plates and prevent them from deviating on the inclined conveying path. Second adjusting plates on both sides of the horizontal conveying path can be driven to rotate so that the two second adjusting plates can move synchronously towards or away from each other, so that the guide wheels can contact steel plates of different widths, maintain stable conveying of rolled steel, and prevent the steel plates from deviating on the horizontal conveying path.

[0016] (2) Each rotating column is fitted with a conical rubber pressure block. By adjusting the distance between the pressure block and the rubber contact wheel, the conical surface of the pressure block can limit the steel plate in the direction perpendicular to the inclined conveying path, preventing the steel plate from jumping due to excessive conveying speed. The elastic metal plate at the top of the second adjusting plate on the horizontal conveying path deforms upward when the steel plate passes by. Its reaction force keeps the steel plate in contact with the conveying roller, preventing the steel plate from jumping.

[0017] (3) A second threaded groove is opened on the circumferential surface of the rotating column, and the pressure block is threadedly fitted on it. Rotating the pressure block can adjust the distance between it and the rubber contact wheel, thereby adapting to steel plates of different thicknesses. The second adjusting plate of the horizontal section is installed by sliding guide through a rectangular slide rail, and its bottom threaded sleeve is fitted on the first threaded groove with opposite rotation directions at both ends of the rotating rod. Driving the rotating rod to rotate can make the two second adjusting plates move synchronously to adapt to the conveying of steel plates of different widths. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1-4 This embodiment describes a rolling mill that facilitates material feeding and prevents deviation. It includes a machine body 1 with two conveying paths, one sloping and the other horizontal. Both conveying paths consist of multiple parallel conveying rollers 15. The steel plate first passes through the sloping conveying path and then shifts to the horizontal conveying path under gravity. To prevent deviation on the sloping conveying path, this embodiment uses a set of first adjusting plates 2 on both sides of the sloping conveying path, with the first adjusting plates 2 parallel to the sloping conveying path. Several rotating columns 3 are distributed along the length of the bottom of the two first adjusting plates 2, and all rotating columns 3 are rotatably connected to the first adjusting plates 2. A rubber contact wheel is fixedly sleeved at the end of each rotating column 3. 4. When the steel plate moves on the inclined conveying path, the rubber contact wheel 4 contacts both sides of the steel plate, thereby guiding the steel plate and preventing it from deviating. In addition, in order to prevent the steel plate from jumping on the conveying path due to excessive conveying speed, this embodiment also has a pressure block 5 sleeved on each rotating column 3. The pressure block 5 is located above the rubber contact wheel 4. All pressure blocks 5 have a conical structure that is larger at the top and smaller at the bottom (of course, the conical surface of the pressure block 5 can also be rounded to increase the contact area between the pressure block 5 and the steel plate). The pressure blocks 5 are all made of rubber. During the steel plate conveying process, by controlling the distance between the pressure block 5 and the rubber contact wheel 4, the conical surface of the pressure block 5 can limit the steel plate in the direction perpendicular to the inclined conveying path, preventing the steel plate from jumping during the conveying process.

[0022] Furthermore, two second adjusting plates 6 are arranged on both sides of the horizontal conveying path on the machine body 1. The feed side of the two second adjusting plates 6 has an arc-shaped structure, which mainly serves as a guide to guide the steel plate smoothly into the horizontal conveying path. Guide wheels 7 are rotatably connected to the side of each second adjusting plate 6 facing each other. A curved elastic metal plate 8 is fixed to the top of each second adjusting plate 6. The two elastic metal plates 8 are arranged facing each other. When the steel plate is conveyed on the horizontal conveying path, it passes through the two second adjusting plates 6. Similarly, in order to allow the steel plate to smoothly enter below the second adjusting plate 6, an inclined bevel (not shown in the figure) must be set in the feeding direction of the second adjusting plate 6. After the steel plate enters below the second adjusting plate 6, the elastic metal plate 8 deforms upward. During the conveying process, the steel plate is always in contact with the conveying roller 15 due to the reaction force of the elastic metal plate 8, and will not jump. In addition, multiple balls 9 are rotatably installed in the concave part of each elastic metal plate 8 along its length. The contact between the upper end surface of the steel plate and the balls 9 can reduce the friction between the two.

[0023] In addition, cylinders 10 are installed on the inner wall of the machine body 1 at the positions corresponding to the two first adjusting plates 2. The piston ends of the cylinders 10 are fixedly connected to the corresponding first adjusting plates 2. The distance between the two first adjusting plates 2 can be controlled by the cylinders 10, and the adjusting plates can be pushed so that the rubber contact wheel 4 actively contacts the steel plate, thereby realizing the correction of the rolling body.

[0024] In a preferred embodiment, to accommodate the conveying of steel plates of different widths, two rectangular slide rails 14 are fixed along the width direction of the horizontal section of the machine body 1. The second adjusting plate 6 is slidably guided on the two rectangular slide rails 14. Threaded sleeves 11 are fixedly connected to the bottom ends of the two second adjusting plates 6. A rotating rod 12 is also rotatably installed on the horizontal section of the machine body 1. The rotating rod 12 is distributed parallel to the conveying roller 15. First threaded grooves 13 are opened at both ends of the rotating rod 12, and the rotation directions of the two first threaded grooves 13 are opposite. The threaded sleeves 11 at the bottom of the two second adjusting plates 6 are respectively fitted onto the corresponding first threaded grooves 13. One end of the rotating rod 12 is fixedly connected to the output end of an external motor. When the external motor drives the rotating rod 12 to rotate, it drives the two second adjusting plates 6 to move closer or further away from each other synchronously. When the two second adjusting plates 6 move closer to each other, the guide wheel 7 can contact the steel plate, maintaining stable conveying of the rolled steel.

[0025] Furthermore, in order to accommodate steel plates of different thicknesses, this embodiment also provides a second threaded groove 16 on the circumferential surface of each rotating column 3. All pressure blocks 5 are threaded onto the corresponding second threaded groove 16. By rotating the pressure block 5, the distance between it and the rubber contact wheel 4 can be adjusted, thereby adapting to steel plates of different thicknesses.

[0026] Finally, it should be noted that the conveyor rollers 15 distributed along the sloping conveying path are all rotatably connected to the inner wall of the machine body 1 via damping bearings. A damping bearing is a type of bearing that, based on a traditional bearing, is specially designed or has a specific structure added to generate a damping effect during operation. The damping effect refers to the phenomenon where, during vibration or motion, the amplitude of vibration or motion gradually decreases due to internal or external factors. In a damping bearing, this effect manifests as a certain resistance to the rotation of rotating components, thereby controlling the rotational speed and reducing vibration and impact. The presence of damping bearings can slow down the steel plate during unloading, preventing the steel plate from falling too quickly and causing instability. The conveyor rollers 15 distributed along the horizontal conveying path are all fixedly connected at their shaft centers to the output end of an external motor. The external motor drives the conveyor rollers 15 at these locations to rotate, achieving active conveying of the steel plate and preventing the steel plate from remaining on the conveyor rollers 15.

[0027] The working principle of the above embodiment is as follows: First, after the machine body 1 unloads the steel plate, the steel plate will pass through a sloping conveying path. Since the conveying roller 15 is rotatably connected to the machine body 1 through a damping bearing, and the conveying roller 15 is made of rubber, it can decelerate the steel plate when it falls. Then, the cylinder 10 pushes the two first adjusting plates 2 closer to each other, and makes multiple rubber contact wheels 4 contact the steel plate, thereby correcting the deviation of the rolled steel. During this process, the conical surface of the pressure block 5 forms a limit on the steel plate in the direction perpendicular to the sloping conveying path, preventing the steel plate from deviating during the conveying process. The steel plate is conveyed in a stable and centered manner by jumping. When the steel plate is conveyed to the horizontal section of the conveying path, the conveying roller 15 is driven to rotate by an external motor, so the steel plate will be automatically conveyed forward. At this time, the drive rotating rod 12 rotates, and the two second adjusting plates 6 approach each other, so that the guide wheel 7 contacts the steel plate. The steel plate is conveyed in a centered manner on the conveying roller 15. During the conveying process, the steel plate is always in contact with the conveying roller 15 due to the reaction force of the elastic metal plate 8, so that the steel plate always maintains a stable and centered state on the conveying roller 15, thus achieving stable and centered conveying of the steel plate.
