Description

Technical Field

[0001] The utility model relates to the technical field of steel coil winding and unwinding, in particular to a fixing device for steel coil winding and unwinding. Background Art

[0002] Steel coil winding and unwinding machines are indispensable equipment in the production line. They undertake the tasks of unwinding and winding, jointly ensuring the smooth operation of the production line. During the process of steel coil winding and unwinding, the high-speed movement and weight of the steel strip may cause it to shake. If not clamped and limited, the steel strip may get out of control due to inertia or external factors, resulting in serious consequences such as equipment damage and casualties. And if the steel strip shakes frequently, it may be necessary to frequently adjust the equipment parameters or stop the machine for inspection, thus affecting the production efficiency. In addition, the shaking of the steel strip may cause defects such as scratches and indentations on its surface, affecting the appearance quality and performance of the product. At the same time, the cleanliness of the steel strip surface directly affects its subsequent processing and use performance. If there are impurities such as oil stains and rust on the steel strip surface, it may affect the adhesion and uniformity of processes such as painting and electroplating, reducing the corrosion resistance and aesthetics of the product, and the impurities on the steel strip surface may wear the equipment parts during the winding and unwinding process, resulting in a decline in equipment performance and a shortening of its service life. Therefore, a fixing device for steel coil winding and unwinding is needed to avoid the above problems. Content of the Utility Model

[0021] Embodiment 1

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a fixing device for steel coil rewinding and unwinding.

[0023] In this embodiment, it includes a bottom bracket 1. At the upper end of the bottom bracket 1 and behind two mounting frames 2, a chassis 6 is fixedly installed. A rewinding and unwinding assembly 7 is installed on the chassis 6. During use, the rewinding and unwinding assembly 7 on the chassis 6 can rewind and unwind the steel strip.

[0024] Further, two mounting brackets 2 are symmetrically and fixedly installed at the upper end of the bottom bracket 1. The mounting bracket 2 is composed of a support frame 8 and a mounting plate 9. The mounting plate 9 is fixedly installed at the upper end of the support frame 8. Two first fixing members 3 are symmetrically installed on the two mounting brackets 2. The first fixing member 3 is composed of a fixed roller 14, a moving block 15, a first screw 16 and a moving roller 17. The fixed roller 14 is rotatably installed on the two mounting plates 9 of the two mounting brackets 2. There are two moving blocks 15 which are respectively movably installed on the two mounting plates 9 of the two mounting brackets 2. The moving blocks 15 are simultaneously located above the fixed roller 14. There are two first screws 16 which are respectively rotatably installed on the two moving blocks 15. The first screw 16 is simultaneously installed on the mounting plate 9. The moving roller 17 is rotatably installed on the two moving blocks 15. A second fixing member 4 is simultaneously installed on the two mounting brackets 2. The second fixing member 4 is composed of a second screw 18 and a limiting plate 19. There are two limiting plates 19 which are symmetrically installed on the second screw 18. The limiting plates 19 are simultaneously sleeved on the two fixed rollers 14 and the two moving rollers 17 of the two first fixing members 3. The support frame 8 on the mounting bracket 2 is fixedly connected to the bottom bracket 1. Two first guide grooves 10 and a second guide groove 11 are symmetrically formed on the mounting plate 9 of the mounting bracket 2. The second guide groove 11 is located between the two first guide grooves 10. A guide rod 12 is longitudinally and fixedly installed in the second guide groove 11. A mounting hole 13 is formed on the mounting plate 9 and below the second guide groove 11. Two shaft holes are formed on the mounting plate 9 and below the two first guide grooves 10. Two threaded holes are formed at the upper end of the mounting plate 9. The threaded holes communicate with the first guide grooves 10. The fixed roller 14 on the first fixing member 3 is rotatably installed in the shaft hole formed on the mounting plate 9. The moving block 15 is movably installed in the first guide groove 10. The first screw 16 is installed in the threaded hole formed at the upper end of the mounting plate 9. A shaft hole is formed on the moving block 15. The moving roller 17 is rotatably installed in the shaft hole formed on the moving block 15. The second screw 18 on the second fixing member 4 is rotatably installed in the mounting hole 13. Threaded holes and two through grooves 20 are formed on the limiting plate 19. The limiting plate 19 is installed on the second screw 18 through the threaded hole. The limiting plate 19 is simultaneously sleeved on the fixed roller 14 and the moving roller 17 through the through grooves 20. When winding and unwinding the steel coil, the steel strip can be passed through between the fixed roller 14 and the moving roller 17 on the first fixing member 3. At this time, the steel strip will be placed on the fixed roller 14. Then, the first screw 16 can be rotated to adjust the height of the moving roller 17 so that the moving rollers 17 can all contact the steel strip. When the first screw 16 is rotated, the first screw 16 will move upward or downward in the threaded hole on the mounting plate 9. At this time, the first screw 16 will push the moving block 15 downward, so that the moving block 15 will drive the moving roller 17 to move downward until the moving roller 17 contacts the steel strip. Thus, the fixed roller 14 and the moving roller 17 are used to longitudinally limit the steel strip. At the same time, the steel strip is passed through between the two limiting plates 19 on the second fixing member 4. Then, the second screw 18 is rotated to adjust the distance between the two limiting plates 19.As a result, the limiting plates 19 are close to the left and right ends of the steel strip, and then the two limiting plates 19 are used to laterally limit the steel strip, and finally the fixing of the steel strip is completed. When the second screw 18 rotates in the mounting hole 13, the two limiting plates 19 will move, that is, they will approach or move away from each other, ultimately preventing the steel strip from shaking during the winding and unwinding process, thus avoiding the steel strip from getting out of control due to inertia or external factors, resulting in serious consequences such as equipment damage and casualties. At the same time, it also avoids frequently adjusting equipment parameters or stopping the machine for inspection, thereby ensuring production efficiency, and avoiding defects such as scratches and indentations on the surface of the steel strip caused by its shaking, which affect the appearance quality and performance of the product.

[0025] Embodiment 2

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 4 As shown in, based on the same concept as the above Embodiment 1, this embodiment also proposes a cleaning structure.

[0027] In this embodiment, it includes a cleaning member 5. The cleaning member 5 is installed on the two mounting brackets 2. The cleaning member 5 is composed of a spring 21, a substrate 22, and a rubber scraping strip 23. There are two of the spring 21, the substrate 22, and the rubber scraping strip 23. The two substrates 22 are respectively fixedly installed at the upper and lower ends of the two springs 21. The two rubber scraping strips 23 are respectively fixedly installed at the inner ends of the two substrates 22. The spring 21 and the substrate 22 on the cleaning member 5 are both located in the second guide groove 11. The substrate 22 is provided with holes, and the substrate 22 is movably installed on the guide rod 12 through the holes opened thereon. The spring 21 is also sleeved on the guide rod 12. The rubber scraping strip 23 is located between the two mounting brackets 2. When winding and unwinding the steel coil, the steel strip needs to pass through between the two rubber scraping strips 23 on the cleaning member 5. At this time, the rubber scraping strips 23 will approach each other under the elastic tension of the spring 21, so that the rubber scraping strips 23 can come into contact with the surface of the steel strip. As the steel strip is wound and unwound, the rubber scraping strips 23 can rub against the steel strip, thereby scraping off the debris on the surface of the steel strip, and then ensuring the cleanliness of the surface of the steel strip, and further avoiding the steel strip being too dirty and directly affecting its subsequent processing and use performance. At the same time, it can also avoid the impurities on the surface of the steel strip from possibly wearing the equipment parts during the winding and unwinding process, resulting in a decline in equipment performance and a shortening of the service life.
