Description

Technical Field

[0001] This application relates to the field of strip steel processing technology, specifically a strip steel uncoiling device. Background Technology

[0002] Steel strip is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of different industrial sectors for the industrialized production of various metal or mechanical products.

[0003] An existing patent (publication number: CN214417346U) discloses a strip steel uncoiling device, relating to the field of strip steel processing. It includes a base, pressure rollers, and a conveyor table. A first motor is fixedly installed on one side of the base. The output end of the first motor is provided with a first threaded rod. Two sliders are symmetrically arranged on the surface of the first threaded rod. A first connecting rod and a second connecting rod are respectively provided on the top of each slider. This device allows for height adjustment, facilitating material loading and improving work efficiency. It also maintains a consistent height with the conveyor table, preventing uneven tension caused by the coil shrinking and friction damage to the strip steel, thus improving safety during strip steel processing. The inclusion of a third motor, a second threaded rod, connecting blocks, pressure rollers, and auxiliary rollers allows for straightening of the strip steel during uncoiling, further improving production efficiency.

[0004] The aforementioned strip uncoiling device is inconvenient during coil installation or disassembly, increases the difficulty of uncoiling operations, reduces work efficiency, and the straightening effect of strip steel using only a single auxiliary roller and pressure roller is not good, leaving room for improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a strip steel uncoiling device, which has the advantages of facilitating the installation and disassembly of strip steel coils, improving work efficiency, and optimizing the straightening effect of strip steel, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a strip steel uncoiling device, comprising a base plate, a frame fixedly connected to the upper surface of the base plate, a rotating shaft rotatably connected inside the frame, a coil slidably connected to the outer circumference of the rotating shaft, a strip steel coil sleeved on the outside of the coil, a positioning plate fixedly sleeved on the outer circumference of the rotating shaft, a positioning ring threadedly connected to the outer circumference of the rotating shaft via a threaded structure, two side plates fixedly connected to the upper surface of the base plate, a lower conveying roller rotatably connected between the two side plates, a first bracket fixedly connected to the outer surface of the two side plates, a first hydraulic cylinder fixedly connected to the top of the first bracket, a first lifting frame fixedly connected to the output end of the first hydraulic cylinder, an upper conveying roller rotatably connected inside the first lifting frame, a base fixedly connected to the upper surface of the base plate, equidistantly arranged lower straightening rollers rotatably connected to the top of the base, a second bracket fixedly connected to the outer surface of the base, a second hydraulic cylinder fixedly connected to the top of the second bracket, and equidistantly arranged upper straightening rollers rotatably connected inside the output end of the second hydraulic cylinder.

[0007] The above scheme facilitates the installation and disassembly of strip steel coils and optimizes the straightening effect during the strip steel uncoiling process. By setting a rotating shaft, a first positioning plate fixedly connected to the rotating shaft, and a positioning ring threadedly connected to the rotating shaft, the installation or disassembly of the coil with the strip steel coil is facilitated, improving work efficiency. By setting a lower conveying roller and a liftable upper conveying roller, the uncoiling and conveying operation of the strip steel coil can be completed. By setting equidistant lower straightening rollers and equidistant, liftable upper straightening rollers, multiple straightening operations can be performed simultaneously during the uncoiling process of the strip steel coil, fully optimizing the straightening effect of the strip steel coil.

[0008] Furthermore, a keyway is provided inside the rotating shaft, and a limit key is fixedly connected to the inner wall of the drum. The limit key is slidably connected to the rotating shaft through the keyway.

[0009] The above solution involves creating a keyway inside the shaft and setting a limiting key on the inner wall of the drum, allowing the limiting key to slide through the keyway and connect with the shaft. This design ensures that the drum is accurately positioned when installed on the shaft and that there is no relative rotation during rotation, thus guaranteeing the stability of the strip steel coil uncoiling, avoiding uncoiling failures caused by relative rotation between the drum and the shaft, and improving the reliability of the uncoiling operation.

[0010] Furthermore, two guide plates are fixedly connected to the outer surface of the first lifting frame, and two guide grooves are opened on the inner wall of the first support. The guide plates are slidably connected to the first support through the guide grooves.

[0011] The above scheme provides precise guidance for the lifting of the first lifting frame, ensuring that the upper conveyor roller remains stable during the lifting process and avoiding swaying or deviation. This guarantees the matching accuracy between the upper and lower conveyor rollers and ensures the smooth operation of the strip steel coil uncoiling and conveying.

[0012] Furthermore, adjacent lower straightening rollers are connected by chain and sprocket drive, and adjacent upper straightening rollers are connected by chain and sprocket drive.

[0013] The above scheme achieves synchronous rotation between multiple lower straightening rollers or multiple upper straightening rollers through chains and sprockets, ensuring consistent rotational speeds among the straightening rollers, resulting in uniform force on the strip during straightening and improving the consistency of the straightening effect.

[0014] Furthermore, a drive motor is provided at the end of the lower conveying roller, a drive motor is provided at the end of one of the lower straightening rollers, and a drive motor is provided at the end of one of the upper straightening rollers.

[0015] The above scheme provides drive motors for the lower conveying roller, lower straightening roller, and upper straightening roller, which can provide power to the lower conveying roller, lower straightening roller, and upper straightening roller, thereby completing the conveying and straightening operations of the strip steel coil.

[0016] Furthermore, four guide rods are fixedly connected to the upper surface of the second lifting frame, and the outer circumferential surface of each guide rod is slidably inserted into the interior of the second support.

[0017] Through the above scheme, the guide rod can provide additional guidance and support for the lifting of the second lifting frame, enhance the stability of the upper straightening roller lifting, prevent the upper straightening roller from shaking or tilting during the lifting process, ensure the matching accuracy between the upper and lower straightening rollers, and improve the quality of the straightening operation.

[0018] Furthermore, the lower straightening roller and the upper straightening roller are arranged alternately.

[0019] With the above scheme, this layout allows the strip steel to be subjected to multiple bending actions in different directions when passing through the straightening rollers, which can more effectively eliminate defects such as bending and wavy strip steel, improve the straightening effect, and make the flatness of the strip steel reach a higher standard.

[0020] Furthermore, two limiting rings are fixedly sleeved on the outer circumferential surface of the rotating shaft. The two limiting rings are respectively disposed on both sides of the frame, and the side of the limiting ring closer to the frame contacts the outer surface of the frame.

[0021] Through the above scheme, the setting of the limit ring can restrict the axial movement of the rotating shaft within the frame, ensure the stability of the rotating shaft during rotation, avoid the positional deviation of the drum caused by the axial movement of the rotating shaft, and thus affect the uncoiling operation of the strip steel coil, thereby improving the operational stability and reliability of the equipment.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This strip steel uncoiling device, by setting a rotating shaft, a first positioning plate fixedly connected to the rotating shaft, and a positioning ring threadedly connected to the rotating shaft, facilitates the installation or disassembly of the coil with the strip steel coil, improving work efficiency. By setting a lower conveying roller and a liftable upper conveying roller, it can complete the uncoiling and conveying operation of the strip steel coil. By setting an equidistant lower straightening roller and an equidistant upper straightening roller that can be adjusted in height, it can simultaneously perform multiple straightenings during the uncoiling process of the strip steel coil, fully optimizing the straightening effect of the strip steel coil.

[0025] 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.

[0026] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a strip steel uncoiling device includes a base plate 1, a frame 2 fixedly connected to the upper surface of the base plate 1, a rotating shaft 3 rotatably connected inside the frame 2, a roll 4 slidably connected to the outer circumferential surface of the rotating shaft 3, a strip steel roll being sleeved on the outside of the roll 4, a positioning plate 5 fixedly sleeved on the outer circumferential surface of the rotating shaft 3, and a positioning ring 6 threadedly connected to the outer circumferential surface of the rotating shaft 3 through a threaded structure.

[0027] Please see Figure 1 and Figure 4 Two side plates 7 are fixedly connected to the upper surface of the base plate 1. A lower conveying roller 8 is rotatably connected between the two side plates 7. A first bracket 9 is fixedly connected to the outer surface of the two side plates 7. A first hydraulic cylinder 10 is fixedly connected to the top of the first bracket 9. A first lifting frame 11 is fixedly connected to the output end of the first hydraulic cylinder 10. An upper conveying roller 12 is rotatably connected inside the first lifting frame 11.

[0028] Please see Figure 1 , Figure 5 and Figure 6 A base 13 is fixedly connected to the upper surface of the base plate 1. The top of the base 13 is rotatably connected to the lower straightening rollers 14 arranged at equal intervals. A second bracket 15 is fixedly connected to the outer surface of the base 13. A second hydraulic cylinder 16 is fixedly connected to the top of the second bracket 15. The output end of the second hydraulic cylinder 16 is fixedly connected to the interior of the second lifting frame 17, and the upper straightening rollers 18 arranged at equal intervals are rotatably connected to it.

[0029] Please see Figure 2 and Figure 3 The rotating shaft 3 has a keyway 19 inside, and a limit key 20 is fixedly connected to the inner wall of the drum 4. The limit key 20 is slidably connected to the rotating shaft 3 through the keyway 19. By opening the keyway 19 inside the rotating shaft 3 and setting the limit key 20 on the inner wall of the drum 4, the limit key 20 is slidably connected to the rotating shaft 3 through the keyway 19. This design can ensure that the drum 4 is accurately positioned when installed on the rotating shaft 3 and will not rotate relative to the shaft during rotation, thus ensuring the stability of the strip steel coil uncoiling, avoiding uncoiling failures caused by relative rotation between the drum 4 and the rotating shaft 3, and improving the reliability of the uncoiling operation.

[0030] Please see Figure 1 and Figure 4 Two guide plates 21 are fixedly connected to the outer surface of the first lifting frame 11, and two guide grooves 22 are opened on the inner wall of the first support 9. The guide plates 21 are slidably connected to the first support 9 through the guide grooves 22, providing precise guidance for the lifting of the first lifting frame 11, so that the upper conveying roller 12 remains stable during the lifting process and avoids shaking or deviation, thereby ensuring the matching accuracy between the upper conveying roller 12 and the lower conveying roller 8, and ensuring the smooth operation of the strip steel coil uncoiling and conveying operation.

[0031] Please see Figure 5 The adjacent lower straightening rollers 14 are connected by chain and sprocket drive, and the adjacent upper straightening rollers 18 are connected by chain and sprocket drive. The chain and sprocket drive enables the synchronous rotation of multiple lower straightening rollers 14 or multiple upper straightening rollers 18, ensuring that the speed of the straightening rollers is consistent, so that the strip is subjected to uniform force during the straightening process and the consistency of the straightening effect is improved.

[0032] Please see Figure 1 , Figure 4 and Figure 5 A drive motor is provided at the end of the lower conveying roller 8, a drive motor is provided at the end of one of the lower straightening rollers 14, and a drive motor is provided at the end of one of the upper straightening rollers 18. The drive motors provided for the lower conveying roller 8, the lower straightening roller 14, and the upper straightening roller 18 can provide power to the lower conveying roller 8, the lower straightening roller 14, and the upper straightening roller 18, thereby completing the conveying and straightening operation of the strip steel coil.

[0033] Please see Figure 1 , Figure 5 and Figure 6 Four guide rods 23 are fixedly connected to the upper surface of the second lifting frame 17. The outer circumferential surface of the guide rods 23 is slidably inserted into the interior of the second bracket 15. The guide rods 23 can provide additional guidance and support for the lifting of the second lifting frame 17, enhance the stability of the lifting of the upper straightening roller 18, prevent the upper straightening roller 18 from shaking or tilting during the lifting process, ensure the matching accuracy between the upper straightening roller 18 and the lower straightening roller 14, and improve the quality of the straightening operation.

[0034] Please see Figure 5 and Figure 6 The lower straightening roller 14 and the upper straightening roller 18 are arranged alternately. This layout allows the strip to be subjected to multiple bending actions in different directions when passing through the straightening rollers, which can more effectively eliminate defects such as bending and wavy strip, improve the straightening effect, and make the flatness of the strip reach a higher standard.

[0035] Please see Figure 2 and Figure 3 Two limiting rings 24 are fixedly sleeved on the outer circumferential surface of the rotating shaft 3. The two limiting rings 24 are respectively set on both sides of the frame 2. The side of the limiting ring 24 closer to the frame 2 contacts the outer surface of the frame 2. The setting of the limiting rings 24 can restrict the axial movement of the rotating shaft 3 within the frame 2, ensure the stability of the rotating shaft 3 during rotation, avoid the position displacement of the drum 4 caused by the axial movement of the rotating shaft 3, and thus affect the uncoiling operation of the strip steel coil, thereby improving the operational stability and reliability of the equipment.

[0036] In this embodiment, a strip steel uncoiling device is provided. By setting a rotating shaft 3, a first positioning plate 5 fixedly connected to the rotating shaft 3, and a positioning ring 6 threadedly connected to the rotating shaft 3, it facilitates the installation or disassembly of the coil 4 with the strip steel coil wound on it, thereby improving work efficiency. By setting a lower conveying roller 8 and a liftable upper conveying roller 12, the uncoiling and conveying operation of the strip steel coil can be completed. By setting an equidistant lower straightening roller 14 and an equidistant upper straightening roller 18 that can be adjusted in height, multiple straightening can be performed simultaneously during the uncoiling process of the strip steel coil, thereby fully optimizing the straightening effect of the strip steel coil.

[0037] It should be noted that the outer circumferential surface of the positioning ring 6 is provided with anti-slip protrusions arranged at equal intervals.

[0038] The working principle of the above embodiments is as follows: A drum 4, wound with strip steel, is fitted onto a rotating shaft 3. The limiting key 20 on the inner wall of the drum 4 slides along the keyway 19 inside the rotating shaft 3, ensuring precise installation of the drum 4. Then, the positioning ring 6 is rotated, utilizing its threaded structure to move along the rotating shaft 3 until it is in close contact with the end face of the drum 4. The positioning plate 5 then securely fixes the drum 4 to the rotating shaft 3, facilitating installation and disassembly. During strip steel uncoiling and conveying, one end of the strip steel is clamped between the lower conveyor roller 8 and the upper conveyor roller 12. The output end of the first hydraulic cylinder 10 extends, pushing the first lifting frame 11 downwards, causing the upper conveyor roller 12 to descend smoothly and cooperate with the lower conveyor roller 8 to clamp the strip steel coil. The drive motor at the end of the lower conveyor roller 8 is started to rotate it. Under the frictional force of the lower conveyor roller 8, the strip steel coil is pulled out of the drum 4, achieving… The uncoiling conveyor guides the strip steel in the conveying process to the space between the lower straightening roller 14 and the upper straightening roller 18. The drive motor at the end of one of the lower straightening rollers 14 is started, driving all the lower straightening rollers 14 to rotate synchronously through chain and sprocket transmission. At the same time, the drive motor at the end of one of the upper straightening rollers 18 is started, driving all the upper straightening rollers 18 to rotate synchronously in the same way. The output end of the second hydraulic cylinder 16 extends or retracts, pushing the second lifting frame 17 to rise and fall, so that the upper straightening rollers 18 rise and fall to adjust the gap between them and the lower straightening rollers 14, adapting to the straightening requirements of strip steel of different thicknesses. When the strip steel passes through the staggered lower straightening rollers 14 and upper straightening rollers 18, it is subjected to multiple bending actions in different directions, effectively eliminating defects such as bending and wavy lines, achieving multiple straightening, improving flatness, and optimizing the straightening effect.
