Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a steel coil uncoiling and leveling device. Background Technology

[0002] Before subsequent processing of steel coils (such as cutting and stamping), the coils must be uncoiled and leveled to eliminate bending stress and ensure a smooth surface. Additionally, during production and storage, oxide scale easily forms on the surface of the steel coils. If this scale is not removed, it will affect the quality of subsequent painting, welding, and other processes, and may also cause wear and tear on processing equipment.

[0003] In existing technologies, "uncoiling and leveling" and "descaling" of steel coils are usually two independent processes: first, the steel is leveled using uncoiling and leveling equipment, and then the leveled steel is transferred to pickling or alkaline washing equipment to remove the oxide scale. This separate processing method has obvious drawbacks: 1. The process is cumbersome, requiring additional transfer equipment and resulting in low processing efficiency; 2. The steel surface is easily contaminated during transfer, affecting the descaling effect. In addition, some single descaling equipment only uses a single alkaline or acid solution for treatment, which has limited effectiveness in removing stubborn oxide scale and cannot meet the requirements of high-precision processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel coil uncoiling and leveling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A steel coil uncoiling and leveling device includes a base plate, a motor fixedly connected to the base plate, the output end of the motor fixedly connected to a round rod, the round rod rotatably connected to the base plate, a housing fixedly connected to the base plate, two pump bodies fixedly connected to the housing, the two pump bodies respectively connected to two cavities of the housing, each pump body fixedly connected to a pipe assembly, one end of each pipe assembly fixedly penetrating the housing, each pipe assembly fixedly connected to a corrugated pipe, multiple corrugated pipes fixedly connected to corresponding pipe bodies, multiple pipe bodies fixedly penetrating the same frame, multiple first rollers rotatably connected to the housing, multiple second rollers rotatably connected to the frame, multiple nozzles fixedly connected to the top or bottom of each pipe body and pipe assembly, push rods fixedly connected to the four corners of the frame, the other ends of the multiple push rods fixedly connected to the same base plate.

[0006] Preferably, the base plate is fixedly connected to multiple spring telescopic rods, the multiple spring telescopic rods are fixedly connected to the same plate body, and the plate body is rotatably connected to two third rollers, the two third rollers being located at the bottom of the round rods.

[0007] Preferably, the round rod is threaded with a threaded sleeve.

[0008] Preferably, the housing is fixedly connected to two valve bodies, and the two valve bodies are respectively connected to two cavities of the housing.

[0009] Preferably, portions of the two tube groups are placed on one side of the corresponding first roller.

[0010] Preferably, the plurality of tubes are located between two corresponding second rollers.

[0011] Preferably, the plurality of first rollers are located on the same plane, and the plurality of second rollers are located on the same plane.

[0012] The beneficial effects of this utility model are as follows: 1. Through the coordination of the set housing, pump body, pipe assembly, corrugated pipe, frame, nozzle, pipe body, first roller, second roller, and push rod, the push rod drives the frame to move up and down, which can flexibly adjust the distance between the second roller and the first roller, and between the pipe body and the pipe assembly. This can accommodate steel coils of different thicknesses, ensuring stable and effective leveling operation of the steel coil by the first and second rollers. At the same time, it can simultaneously pass through the two cavities of the housing, and with the help of the corresponding pump body, draw alkaline or acidic solutions, which are then sprayed onto the steel coil through the nozzles at the pipe assembly and pipe body. This design, on the one hand, “ The two independent processes of "uncoiling and leveling" and "de-scaling" are integrated, eliminating the need for additional transfer equipment, simplifying process connections, effectively solving the problem of low processing efficiency in existing technologies, and avoiding secondary contamination of the steel surface during transfer, thus ensuring the de-scaling effect. On the other hand, the synergistic spraying of alkaline and acidic solutions can more thoroughly remove stubborn oxide scale from the surface of steel coils compared to single solution treatment, meeting the requirements of high-precision processing and comprehensively overcoming the shortcomings of existing technologies such as process separation, high risk of contamination, and limited de-scaling effect. 2. Through the coordination between the spring telescopic rod, the plate, and the third roller, after the steel coil is placed on the round rod, the spring telescopic rod drives the plate to make the third roller contact the bottom of the steel coil. On the one hand, the elastic characteristics of the spring telescopic rod can adapt to steel coils of different diameters, allowing the third roller to fit the bottom of the steel coil without manual adjustment, effectively solving the problem that the fixed support structure is difficult to adapt to steel coils of various specifications, ensuring the stability of the steel coil placement. On the other hand, the buffering effect of the spring can prevent the third roller from forming a rigid contact with the bottom of the steel coil, preventing scratches on the surface of the steel coil, while continuously providing a soft and stable support force, reducing the shaking of the steel coil during subsequent leveling and descaling processes, and ensuring processing accuracy. In addition, this automatic contact design requires no additional manual operation, simplifies the positioning process after the steel coil is loaded, further improves the overall processing efficiency, and avoids process delays caused by manual adjustment of the support structure.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, referring to Figures 1 to 5A steel coil uncoiling and leveling device includes a base plate 1, with a motor 2 fixedly connected to the base plate 1. The model of the motor 2 is selected according to actual working requirements. The output end of the motor 2 is fixedly connected to a round rod 3, which is rotatably connected to the base plate 1, allowing the round rod 3 to rotate synchronously with the motor 2 to achieve stable rotation. This provides a continuous and reliable power transmission path for the uncoiling and conveying of the steel coil after it is placed on the round rod 3. A housing 4 is fixedly connected to the base plate 1, and two pumps 5 are fixedly connected to the housing 4. The model of the pumps 5 is selected according to actual working requirements. The two pumps 5 are respectively connected to two cavities of the housing 4, corresponding to different cavities of the housing 4. Their main function is to extract different types of processing solutions stored in the housing 4. The model of the pump needs to be determined based on the actual processing requirements, such as the viscosity of the solution, the required conveying pressure, and the conveying volume, to ensure stable and efficient delivery of the solution to the subsequent spraying components, meeting the solution supply needs of the descaling process. Both pump bodies 5 are fixedly connected to pipe assemblies 6, providing a smooth transition for subsequent connection to the corrugated pipe 7 and ensuring a smooth solution delivery path. One end of each pipe assembly 6 is fixedly inserted through the housing 4, and both pipe assemblies 6 are fixedly connected to the corrugated pipe 7. This fully utilizes the flexible extension and bending characteristics of the corrugated pipe 7, providing adaptability for the subsequent pipe body 10 to move with the frame 8, preventing damage to the pipe assembly 6 or pipe body 10 due to the lifting or lowering of the frame 8. Simultaneously, the corrugated pipe 7 maintains good sealing performance, preventing solution leakage. During the transport process, liquid leaks from the connection points to ensure a clean operating environment. Multiple corrugated pipes 7 are fixedly connected to corresponding pipe bodies 10, allowing for smooth transport from the pipe group 6 to each pipe body 10. This ensures that each pipe body 10 can independently receive the solution, guaranteeing the spraying performance of the nozzles 9 at different locations. The fixed connection further enhances the sealing of the solution transport. Multiple pipe bodies 10 are fixedly connected to the same frame 8. Multiple first rollers 11 are rotatably connected to the box 4, and multiple second rollers 12 are rotatably connected to the frame 8. The squeezing force between the second rollers 12 and the first rollers 11 straightens the bent parts on the surface of the steel coil, ensuring a smooth surface after processing to meet subsequent processing requirements. Multiple nozzles 9 are fixedly connected to the top or bottom of multiple tube bodies 10 and tube groups 6, which spray the treatment solution delivered by the tube bodies 10 and tube groups 6 evenly onto the surface of the steel coil in the form of spraying. The layout and spraying angle of the nozzles 9 need to be optimized to ensure that the surface of the steel coil can contact the solution in all directions without dead angles, thereby improving the uniformity and thoroughness of descaling. At the same time, the fixed connection can prevent the nozzles 9 from shifting due to spraying pressure. Push rods 13 are fixedly connected to the four corners of the frame body 8. The push rods 13 are electric telescopic rods, and the model is selected according to the actual working requirements. The other end of multiple push rods 13 is fixedly connected to the same base plate 1. The push rods 13 are used to drive the frame body 8 to move up and down, thereby adjusting the distance between the second roller body 12 and the first roller body 11.

[0017] In this embodiment, the base plate 1 is fixedly connected to multiple spring telescopic rods 14 as elastic support components, mainly providing adaptively adjustable support force for the subsequent plate 15. The elastic characteristics of the spring telescopic rods 14 enable them to automatically adjust the support height according to the specifications of the steel coil without manual intervention. Simultaneously, the fixed connection ensures that there will be no positional shift during operation, guaranteeing support stability. Multiple spring telescopic rods 14 are fixedly connected to the same plate 15, and the plate 15 is rotatably connected to two third rollers 16. The two third rollers 16 are located at the bottom of the round rod 3, providing support from the bottom of the steel coil. During the uncoiling and conveying process of the steel coil, the third roller 16 rotates synchronously with the movement of the steel coil, which reduces the friction between the bottom of the steel coil and the supporting components, avoids scratching the surface of the steel coil, and provides stable bottom support for the steel coil to prevent it from sagging. The round rod 3 is threadedly connected to a threaded sleeve 17, which axially limits the steel coil fitted on the round rod 3 to prevent the steel coil from shifting along the axis of the round rod 3 during the uncoiling process, ensuring that the steel coil is always conveyed within the preset processing range and improving the accuracy of steel coil processing. The housing 4 is fixedly connected to two valve bodies 18, which are respectively connected to the housing 4. The two chambers are connected and used to control the inflow and outflow of solution into the corresponding chamber of the tank 4. By opening or closing the valve 18, the solution in the tank 4 can be replenished, discharged, or sealed to ensure that the tank 4 always has a sufficient solution volume to meet processing requirements. At the same time, when the equipment is stopped, the valve 18 can be closed to prevent solution leakage. Some branches of the two pipe groups 6 are respectively placed on one side of the corresponding first roller 11 to ensure that the steel coil is fully covered by the solution sprayed from the nozzle 9 when it is conveyed by the first roller 11, thereby improving the contact efficiency between the solution and the oxide scale on the surface of the steel coil, and also preventing the solution from being sprayed onto the equipment. To reduce corrosion of other non-essential components, multiple tubes 10 are positioned between two corresponding second rollers 12, ensuring that all parts of the steel coil surface can be evenly contacted with the treatment solution, avoiding spray dead zones, and further improving the thoroughness of descaling. At the same time, this position design will not interfere with the leveling operation of the second rollers 12 on the steel coil. Multiple first rollers 11 are all located on the same plane, and multiple second rollers 12 are all located on the same plane, ensuring that the upper and lower squeezing forces are evenly distributed on the surface of the steel coil during leveling, improving the leveling effect, and ensuring that the surface of the steel coil is flat and meets the standards after treatment.

[0018] The working principle of this embodiment is as follows: When the steel coil is placed on the round rod 3, the spring telescopic rod 14 drives the plate 15 to make the third roller 16 contact the bottom of the steel coil. Its elastic characteristics can adapt to steel coils of different diameters, allowing the third roller 16 to fit snugly against the bottom of the steel coil without manual adjustment to ensure stable placement. Simultaneously, the spring's buffering effect prevents rigid contact between the third roller 16 and the bottom of the steel coil, preventing scratches on the steel coil surface, and continuously provides soft and stable support to reduce swaying of the steel coil during subsequent processing and ensure processing accuracy. Then, the push rod 13 is connected to an external power supply and control device for operation. The push rod 13 drives the frame 8 to move up and down, flexibly adjusting the distance between the second roller 12 and the first roller 11, and between the tube 10 and the tube group 6. This adapts to steel coils of different thicknesses and ensures stable and effective leveling operation of the first roller 11 and the second roller 12 on the steel coil. Finally, the motor 2 and pump 5 are both connected to an external power supply and control device for operation. The motor 2 can then drive... The moving rod 3 releases the steel coil. In conjunction with multiple first rollers 11 connected to an external drive device, such as a motor, the rotation of the multiple first rollers 11 can pull the steel coil for leveling operations by conveying it between the multiple first rollers 11 and the second rollers 12. At the same time, it can simultaneously pass through the two cavities of the housing 4, where the corresponding pump 5 draws alkaline or acidic solutions, which are then sprayed onto the steel coil through the nozzles 9 at the pipe assembly 6 and the pipe body 10. This design integrates the two independent processes of "uncoiling and leveling" and "de-scaling" without the need for additional transfer equipment, simplifying the process connection and effectively solving the problem of low processing efficiency in existing technologies. It also avoids secondary contamination of the steel surface during transfer and ensures the de-scaling effect. Furthermore, the synergistic spraying of alkaline and acidic solutions can more thoroughly remove stubborn oxide scale from the surface of the steel coil compared to single solution treatment, meeting the requirements of high-precision processing and comprehensively overcoming the shortcomings of existing technologies such as process separation, high risk of contamination, and limited de-scaling effect.
