Description

Technical Field

[0001] This invention relates to the field of hot-rolled steel strip production technology, and more particularly to a coiling structure for hot-rolled steel strip production. Background Technology

[0002] Hot-rolled steel strip refers to thin, narrow coiled steel sheets produced through a hot-rolling process. It is typically categorized by width into narrow strip and wide strip. Narrow strip: The width is usually less than 600mm, and the thickness is generally no more than 12mm. It is commonly used in the manufacture of welded pipes, bicycles, and small hardware parts. Wide strip: The width is greater than 600mm, and the thickness ranges widely, from extremely thin 1.0mm to over 20mm. It has a wide range of applications and is a common raw material in the automotive, shipbuilding, bridge, and pressure vessel industries. It is produced by heating steel billets (slabs or continuously cast billets) to the austenitizing temperature (usually above 1000°C), then continuously rolling them through a series of roughing and finishing mills, and finally coiling them at a high temperature (usually 500-750°C) using a coiler. When the existing winding structure winds up the steel strip, the workers need to manually use pliers to clamp and pull the end of the hot-rolled steel strip. After the end of the steel strip moves into the winding structure, the workers often need to bend the end of the steel strip to increase the contact area between the end of the steel strip and the winding structure, and then control the winding structure to wind it up. During winding, the subsequent steel strip is pulled and wound by the friction between the winding structure and the steel strip. This method of pulling the steel strip by friction reduces the stability of the traction on the end of the steel strip during winding, which not only increases the probability of the end of the steel strip falling off when the device rotates, but also increases the safety hazards for the operators.

[0003] Therefore, it is necessary to provide a new coiling structure for hot-rolled steel strip production to solve the above-mentioned technical problems. Summary of the Invention

A rotatably connected driving gear is mounted between the protective cover and the support plate via a rotating shaft. A meshing linkage gear is provided on the exterior of the driving gear. The linkage gear is fixedly fitted on the exterior of the take-up drum. A motor for controlling the rotation of the driving gear is fixedly mounted on the bottom of the support plate.

[0010] Preferably, the thorn removal assembly further includes a bottom shell, and the top of the mounting frame has a through hole for mounting the bottom shell. The top of the bottom shell and the top of the mounting frame are on the same horizontal plane. Symmetrically distributed support plates are fixedly installed on the top of the bottom shell. Guide rollers are rotatably installed inside the support plates on both sides. A transition plate is inserted into the top of the support plate by bolts. The transition plate is fixedly connected to the support plate by nuts. A sliding frame is inserted into the top of the transition plate through a through hole. A transition frame is fixedly installed at the bottom end of the sliding frame. A horizontal rod is fixedly installed inside the transition frame.

[0013] Preferably, a mounting base is fixedly connected to the top of the mounting frame near the push plate, and a hydraulic cylinder for driving the push plate is fixedly mounted between the mounting base and the push plate via a rotating sleeve.

[0014] A method for using a coiling structure produced from hot-rolled steel strip includes the following steps: Step 1: Before use, adjust the height of the positioning roller according to the required width of the steel strip to ensure that its outer wall can smoothly align with the top of the steel strip after it is erected. This will allow the positioning roller to position the top of the steel strip in the later stages, making the outer wall of the coiled steel strip more regular. Step 2: During use, the operator uses clamps to pull the end of the steel strip through the de-tangling assembly and into the gripper assembly; Step 3: Control the movement of the fan-shaped clamping plate in the gripper assembly to clamp the end of the steel strip and make the winding drum rotate to realize the winding of the steel strip; Step 4: During the steel strip winding process, the deburring component can convert the force of the moving steel strip into a vibration force on the cleaning strip, which can scrape and clean the burrs on the top and bottom of the steel strip. Step 5: After completing the winding of the steel strip, first release the fan-shaped clamp from the end of the steel strip, and then control the winding drum to move downwards to release the obstruction and limitation on the horizontal movement trajectory of the steel strip. Step Six: Control the hydraulic cylinder to drive the push plate to swing, pushing the coiled steel strip outward for unloading.

[0015] Compared with related technologies, the coiling structure for hot-rolled steel strip production provided by this invention has the following advantages: 1. After clamping the end of the steel strip into the gripper assembly, the present invention can drive the fan-shaped clamping plate to clamp the end of the steel strip. When the rotating disk rotates, the steel strip can be stably located in the winding drum, reducing the probability that the end of the steel strip will loosen and fall off from the winding drum during winding. This can improve the stability of the steel strip winding and reduce the safety hazards caused by the end of the steel strip falling off during winding. 2. With this invention, once the worker pulls the end of the steel strip into the gripper assembly, the pulling work can be completed without manually using clamps to bend the end of the steel strip, thus reducing the difficulty of the worker's work. 3. In the process of winding the steel strip, the force of the steel strip against the guide roller is transformed into a vibration force on the cleaning plate. This causes the cleaning plate to drive the cleaning strip to vibrate, which in turn polishes the burrs on both sides of the steel strip. Therefore, it can reduce the probability of the operator's hands being cut by burrs during the handling, loading and unloading or subsequent processing of the rolled steel strip. 4. During the winding process of the steel strip, the positioning roller located above the gripper assembly will abut against the top of the steel strip, thereby ensuring that the top of the steel strip winding along the winding drum is always at the same horizontal plane. As a result, after the steel strip is wound, the surface of the wound steel strip is more regular, reducing the phenomenon of unevenness on the outer wall of the steel coil.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 13 The present invention provides a coiling structure for hot-rolled steel strip production. The coiling structure for hot-rolled steel strip production includes: a mounting frame 1, a coiling cylinder 2 for winding the steel strip inside the mounting frame 1, and a push plate 3 for unloading the coiled steel strip on the mounting frame 1.

[0021] In an embodiment of the present invention, please refer to Figures 1 to 13 The winding drum 2 is equipped with a gripper assembly 4, which clamps the end of the steel strip, causing the steel strip to wind and coil around the clamping part as the center. The gripper assembly 4 includes multiple fan-shaped clamping plates 41 for clamping the end of the steel strip, arranged in a ring. By adjusting the spacing between adjacent fan-shaped clamping plates 41, steel strips of different thicknesses can be clamped. The top center of the mounting frame 1 has a mounting groove 12, and an annular guide rail 121 is fixedly installed inside the mounting groove 12. A rotating disk 21 with a rotatable connection is installed. The center of the top of the rotating disk 21 has an open structure, and the inner wall of the opening is rotatably connected to the outer wall of the take-up drum 2. Multiple evenly distributed sliding grooves 201 are provided on the side wall of the take-up drum 2. A protrusion 211 is slidably installed inside the sliding groove 201, and the end of the protrusion 211 is fixedly connected to the inner wall of the opening of the rotating disk 21. Multiple through grooves 202 are also provided on the side wall of the take-up drum 2, and the position of the through groove 202 corresponds one-to-one with the gap between two adjacent fan-shaped clamps 41.

[0022] It should be noted that when workers use clamps to pull the end of the steel strip to move it into the winding drum 2, the position of the through groove 202 corresponds one-to-one with the gap position between the two adjacent sector clamps 41. This allows the steel strip to move more accurately between the two adjacent sector clamps 41 through the through groove 202, reducing the number of times the position of the steel strip end needs to be adjusted. Thus, when the sector clamps 41 are in opposition, the end of the steel strip can be stably clamped. Compared with bending the end of the steel strip to increase the friction between the steel strip and the winding structure components to pull and wind the steel strip, this additional clamping force can improve the stability of the steel strip clamping and pulling, thereby reducing the safety hazard caused by the end of the steel strip jumping out of the winding component during winding. Furthermore, this method eliminates the need for workers to manually bend the ends of the steel strip using clamps, thus reducing the difficulty of their work. After the steel strip end is traction and fixed, the motor can be controlled to rotate, thereby driving the drive gear 23 at the output end to rotate. The drive gear 23 can drive the winding drum 2 located in the support plate 22 and the protective cover 222 to rotate synchronously through meshing with the linkage gear 231 on the outer wall. This allows the winding drum 2 to traction and wind up the steel strip. When the winding drum 2 rotates, the protrusion 211 located in the chute 201 can drive the rotating disk 21 to rotate synchronously by abutting against the inner wall of the chute 201. Thus, during the winding process of the steel strip, the rotating disk 21 that supports the wound steel strip can be kept relatively stationary with the steel strip, thereby reducing the friction between the wound steel strip and the rotating disk 21. Through the sliding connection between the protrusion 211 and the groove 201, the winding drum 2 and the groove 201 are slidably inserted into the rotating disk 21. After the steel strip is wound, the winding drum 2 can retract downwards to the rotating disk 21, so that the top of the winding drum 2 and the top of the rotating disk 21 are at the same level. This releases the winding drum 2 from the restriction on the steel strip roll, making the subsequent sliding unloading of the steel strip roll smoother. Before clamping the steel strip end, the movable sector-shaped clamp 41 is in an unfolded state. When the operator uses clamps to clamp and pull the steel strip end, unfolding the gap between two adjacent sector-shaped clamps 41 will allow the operator to move the steel strip between the sector-shaped clamps 41 more smoothly. At the same time, when the sector-shaped clamp 41 retracts and moves, it can also clamp steel strips of various thicknesses, thus improving the applicability of clamping.

[0023] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 13The gripper assembly 4 also includes a fixing ring 42. A rotatably connected support ring 43 is installed inside the fixing ring 42. Multiple driving inclined blocks 431 that compress the fan-shaped clamping plate 41 are fixedly installed on the inner wall of the support ring 43. A slidably connected guide inclined block 412 is sleeved on the outside of the driving inclined block 431. A fixedly connected guide plate 411 is installed at the top of the guide inclined block 412. The top of the guide plate 411 is fixedly connected to the bottom of the fan-shaped clamping plate 41. An adjusting hydraulic cylinder 421 for adjusting the height of the fixing ring 42 is fixedly mounted between the fixing ring 42 and the mounting frame 1. A fixedly connected mounting ring 44 is sleeved on the bottom of the winding drum 2. Multiple sets of support plates 441 are fixedly installed at the bottom of the mounting ring 44. Each set of support plates 441 includes two plates, and guide rods 442 are fixedly installed between the support plates 441 in the same set. The ends of the guide rods 442 pass through the corresponding guide plates 411 and are opened on the side wall of the guide plates 411. The through hole and the guide plate 411 are slidably connected; the guide rod 442 is a hexagonal prism, and multiple return springs 443 are also sleeved on the outside of the guide rod 442. One end of the return spring 443 is fixedly connected to the corresponding guide plate 411, and the other end of the return spring 443 is fixedly connected to the corresponding support plate 441. The bottom end of the take-up drum 2 extends into the mounting frame 1 and is sleeved with a rotatably connected support plate 22. A drive hydraulic cylinder 221 is fixedly mounted between the support plate 22 and the mounting frame 1. A protective cover 222 is fixedly mounted on the top of the support plate 22. The inside of the protective cover 222 is rotatably connected to the outer wall of the take-up drum 2. A drive gear 23 is rotatably connected between the protective cover 222 and the support plate 22 through a rotating shaft. A linkage gear 231 is meshed with the outside of the drive gear 23. The linkage gear 231 is fixedly sleeved on the outside of the take-up drum 2, and a motor that controls the rotation of the drive gear 23 is fixedly mounted on the bottom of the support plate 22.

[0024] In this embodiment: after the steel strip is wound up and the pressure on the fan-shaped clamping plate 41 is released, the return spring 443 can pull the guide plate 411 by its own force, so that the guide plate 411 can drive the fan-shaped clamping plate 41 to move away from the center of the winding drum 2 on the guide rod 442, so that the fan-shaped clamping plate 41 can release the clamping of the end of the steel strip. During this movement, the hexagonal guide rod 442 can prevent the guide plate 411 from rotating on the guide rod 442, so that the moving strip can be stably placed in the winding drum 2. Meanwhile, since the guide rod 442 is fixedly connected to the take-up drum 2 through the mounting ring 44, when the take-up drum 2 rotates, it can drive the internal fan-shaped clamp 41 to rotate synchronously, thus avoiding the phenomenon of the steel strip end being wrapped due to the asynchronous rotation of the two. Furthermore, during the winding process of the steel strip, the guide block 412, which rotates synchronously with the winding drum 2, can drive the drive block 431 by resisting the outer wall of the drive block 431 inserted inside it. At this time, the drive block 431 will drive the external support ring 43 to rotate synchronously inside the fixed ring 42, thereby avoiding the misalignment of the drive block 431 and the guide block 412 during the winding operation, which would affect the later clamping drive of the fan-shaped clamping plate 41. In this embodiment: the adjusting hydraulic cylinder 421 located between the fixed ring 42 and the mounting frame 1 can adjust the position of the driving inclined block 43 when working independently, so as to control the clamping state of the fan-shaped clamping plate 41 on the steel strip. When it is necessary to unload the coiled steel strip, the adjusting hydraulic cylinder 421 and the driving hydraulic cylinder 221 can be controlled to retract synchronously, so that the driving inclined block 431 and the guide inclined block 412 are always in a relatively static state. This can avoid the driving inclined block 431 blocking the downward sliding trajectory of the guide inclined block 412 when the winding drum 2 is retracted, thus avoiding the obstruction of the winding drum 2 falling, or the driving inclined block 431 moving too far downward and sliding out of the guide inclined block 412, which would affect the subsequent squeezing drive of the guide inclined block 412. It should also be noted that during the winding process, the protective cover 222 located outside the drive gear 23 and the linkage gear 231 can protect the meshing drive gear 23 and the linkage gear 231, thereby preventing external impurities from falling between the drive gear 23 and the linkage gear 231 during the winding of the steel strip and affecting their meshing operation. Before the steel strip is wound up, the telescopic drive hydraulic system can control the height of the winding drum 2 to extend upward according to the program set by the operator, so that the top of the winding drum 2 is always slightly lower than the top of the steel strip after it is erected, so that the top of the erected steel strip can abut against the positioning roller 64 in the shielding assembly 6. It should also be noted that each hydraulic cylinder is equipped with a sensor, an independent proportional valve, and a terminal controller to receive feedback signals from the sensor. This allows an external controller to independently adjust the opening of each proportional valve through algorithms such as PID control and adaptive genetic algorithms, thereby precisely controlling the movement of each hydraulic cylinder. In this way, the controller can, at any time, use software commands to make any specified number of hydraulic cylinders, such as regulating hydraulic cylinder 421 and driving hydraulic cylinder 221, move synchronously as an independent and a whole group, respectively.

[0025] In an embodiment of the present invention, please refer to Figure 7 , Figure 8 , Figure 9 and Figure 1The mounting frame 1 is also equipped with a deburring assembly 5 for cleaning the steel strip. The deburring assembly 5 includes a cleaning plate 55 for scraping the ends of the steel strip and a bottom shell 51. The top of the mounting frame 1 has a through hole 11 for mounting the bottom shell 51. The top of the bottom shell 51 is at the same level as the top of the mounting frame 1. Symmetrically distributed support plates 52 are fixedly installed on the top of the bottom shell 51. Guide rollers 521 are rotatably installed in both support plates 52. A transition plate 53 is bolted to the top of the support plate 52. The transition plate 53 is fixedly connected to the support plate 52 by nuts. A sliding frame 531 is slidably connected to the top of the transition plate 53 through a through hole. A transition frame 54 is fixedly installed at the bottom of the sliding frame 531. A horizontal rod 541 is fixedly installed inside the adapter frame 54. A sliding plate 552 is slidably connected to the outside of the horizontal rod 541. There are two cleaning plates 55, which are symmetrically distributed. The outside of the cleaning plate 55 is fixedly connected to the end of the corresponding sliding plate 552. Cleaning strips 551 are fixedly installed on the opposite ends of the two cleaning plates 55. A plurality of vertical springs 532 are fitted outside the sliding frame 531. One end of the vertical spring 532 is fixedly connected to the sliding frame 531, and the other end of the vertical spring 532 is fixedly connected to the adapter plate 53. A plurality of horizontal springs 542 are fitted outside the horizontal rod 541. One end of the horizontal spring 542 is fixedly connected to the sliding plate 552, and the other end of the horizontal spring 542 is fixedly connected to the adapter frame 54.

[0026] It should be noted that during the steel strip winding process, the guide roller 521 in the deburring assembly 5 guides the steel strip passing through it, changing the angle at which the steel strip moves toward the winding drum 2, so that the winding drum 2 can stably wind the steel strip. During the guiding process, the force generated when it comes into contact with the steel strip is transmitted to the sliding frame 531 and the cleaning plate 55 through the support plate 52, thereby generating a vibration force that drives the sliding frame 531 and the cleaning plate 55. Under the action of the vibration force, the cleaning plate 55 and the cleaning strips 551 on its outer wall can be shaken vertically and horizontally, so that the cleaning strips 551 can scrape and clean the side wall of the steel strip, reducing the burrs on the side wall of the steel strip. At the same time, it can also reduce the probability of the operator's hands being cut by burrs during the subsequent handling, loading and unloading or subsequent processing of the rolled steel strip. The cleaning strips 551 are made of a metal material with a certain degree of flexibility, which reduces the probability of scratching the steel strip during cleaning. In this embodiment, the bottom shell 51 located below the cleaning strip 551 and the cleaning brush collects the burrs and iron filings generated during cleaning, reducing the probability of iron filings splashing randomly with the steel strip. At the same time, since the bottom shell 51 is embedded downwards into the mounting frame 1 through the through hole 11, the top of the bottom shell 51 is at the same level as the top of the mounting frame 1 and the rotating disk 21, which can prevent the steel strip from falling unevenly when passing through the bottom shell 51, thereby helping to improve the regularity of the steel strip after winding.

[0027] In an embodiment of the present invention, please refer to Figure 10 , Figure 11 and Figure 13 The top of the mounting frame 1 is also provided with a shielding component 6 for positioning the steel strip. The shielding component 6 includes a positioning roller 64 that contacts the steel strip and a vertical guide rail 61. The vertical guide rail 61 is fixedly installed on the top of the mounting frame 1. Multiple sliding blocks 621 are inserted inside the vertical guide rail 61. The same support frame 62 is fixedly installed between the multiple sliding blocks 621, and the support frame 62 is rotatably connected to the positioning roller 64 through a shaft. A protruding rod 622 is fixedly installed at the end of the sliding block 621 away from the support frame 62. The end of the protruding rod 622 extends to the outside of the vertical guide rail 61 and is fitted with a threaded cylinder 63. An extrusion plate 631 is fixedly installed at the end of the threaded cylinder 63 near the sliding block 621, and the outer wall of the extrusion plate 631 abuts against the outer wall of the vertical guide rail 61. The end of the threaded cylinder 63 away from the vertical guide rail 61 is a closed structure.

[0028] It should be noted that before winding the steel strip, the operator can control the slider 621 to slide within the vertical guide rail 61 according to the required height of the steel strip to be erected. At the same time, the measurement mark can be made by a scale. When it is moved to the required position, the threaded cylinder 63 can be taken out and screwed onto the protruding rod 622 until the extrusion plate 631 at the end of the threaded cylinder 63 abuts against the outer wall of the vertical guide rail 61. The extrusion force and friction force can lock the slider 621, preventing the slider 621 from sliding randomly. This allows for stepless adjustment of the height of the positioning roller 64. The adjusted positioning roller 64 can keep the top of the steel strip winding along the winding drum at the same horizontal plane during the steel strip winding process, making the surface of the wound steel strip more regular and reducing the phenomenon of unevenness on the outer wall of the steel coil, thus making the outer surface of the wound steel strip coil more regular. In an embodiment of the present invention, please refer to Figure 12 The vertical guide rail 61 and the slider 621 can also be fixed by bolt insertion. This insertion method eliminates the need for staff to use a ruler to measure and mark when adjusting the position of the positioning roller 6444, making it more convenient and faster.

[0029] In an embodiment of the present invention, please refer to Figure 1 , Figure 12 and Figure 13 A mounting base 7 is fixedly connected to the top of the mounting frame 1 near the push plate 3, and a hydraulic cylinder 71 for driving the push plate 3 is fixedly mounted between the mounting base 7 and the push plate 3 through a rotating sleeve.

[0030] It should be noted that the hydraulic cylinder 71, which is mounted between the push plate 3 and the mounting base 7, can swing the push plate 3 around the connection point with the mounting frame 1 when it is extended, thereby allowing the push plate 3 to push the coiled steel strip to be unloaded.

[0031] A method for using a coiling structure produced from hot-rolled steel strip includes the following steps: Step 1: Before use, adjust the height of the positioning roller 64 according to the required width of the steel strip to ensure that its outer wall can smoothly abut against the top of the steel strip after it is erected. This will allow the positioning roller 64 to position the top of the steel strip after winding, making the outer wall of the wound steel strip more regular. Step 2: When using it, the operator uses clamps to pull the end of the steel strip through the de-tangling assembly 5 into the gripper assembly 4; Step 3: Control the movement of the fan-shaped clamping plate 41 in the gripper assembly 4 to clamp the end of the steel strip and make the winding drum 2 rotate to realize the winding of the steel strip. Step 4: During the steel strip winding process, the deburring component 5 can convert the force of the moving steel strip into the vibration force of the cleaning strip 551, so that it can scrape and clean the burrs on the top and bottom of the steel strip. Step 5: After the steel strip is wound and coiled, the fan-shaped clamp 41 can be released from the end of the steel strip, and then the winding drum 2 can be controlled to move downward to release the obstruction limit on the horizontal movement trajectory of the steel strip. Step 6: Control the hydraulic cylinder 71 to drive the push plate 3 to swing, and push the coiled steel strip outward for unloading.

[0032] The working principle of the coiling structure for hot-rolled steel strip production provided by this invention is as follows: In use, the operator can use external clamps to hold the end of the hot-rolled steel strip, and then pull it into the take-up drum 2 through the guide roller 521 in the deburring assembly 5. It then moves through the through-slot 202 on the side wall of the take-up drum 2 to the space between the internal fan-shaped clamps 41. The clamps can then be removed, and the controller on the external terminal controls the extension of the adjusting hydraulic cylinder 421. The extension of the adjusting hydraulic cylinder 421 drives the driving inclined block 431 to move vertically through the fixing ring 42 at its end. The moving driving inclined block 431 then moves the corresponding external guide. When the inclined block 412 is pressed, the inclined surfaces of the driving inclined block 431 and the guide inclined block 412 will change the vertical pressing force of the driving inclined block 431 into the horizontal driving force. This allows the guide inclined block 412 to drive the guide plate 411 to slide on the guide rod 442 toward the center of the winding drum 2. During the sliding process, the guide plate 411 can drive the top fan-shaped clamping plate 41 to move synchronously. At this time, multiple synchronously moving fan-shaped clamping plates 41 will form a clamping claw, which can clamp and fix the end of the steel strip located between two adjacent fan-shaped clamping plates 41. After clamping the end of the steel strip, the controller can also control the motor to drive the drive gear 23 to rotate through the set program. The rotating drive gear 23 can drive the winding drum 2 to rotate in the support plate 22 through meshing with the external linkage gear 231. The rotating winding drum 2 can drive the rotating plate 21 to rotate synchronously through the abutment of the sliding groove 201 on the side wall and the protrusion 211, thereby realizing the winding and wrapping of the steel strip. During the winding process, the guide roller 521 in the deburring assembly 5 can guide the continuously moving steel strip. The force that the steel strip resists the guide roller 521 when it moves will be transformed into a vibration force on the cleaning plate 55. This allows the cleaning plate 55 to swing the cleaning strip 551 on the outer wall to scrape and clean the burrs on the top and bottom sides of the steel strip. This reduces the probability of operators' hands being cut by burrs during the handling, loading and unloading or subsequent processing of the coiled steel strip. Furthermore, during the winding process of the steel strip, the positioning roller 64 located above the winding drum 2 after adjustment can abut against the top of the steel strip, thereby blocking and limiting the top of the steel strip, so that the top of the steel strip winding along the winding drum is always at the same horizontal plane. As a result, after the steel strip is wound, the surface of the wound steel strip is more regular, reducing the phenomenon of unevenness on the outer wall of the steel coil. Therefore, the outer wall of the steel strip coil after winding is more regular. After the steel strip is wound up, the operator can stop the motor from rotating the winding drum 2 through the terminal controller. Then, the operator can control the adjusting hydraulic cylinder 421 to retract the strip. The retracting adjusting hydraulic cylinder 421 will drive the drive inclined block 431 to move downward, releasing the pressure on the guide inclined block 412. At this time, the reset spring 443 on the outer wall of the guide rod 442 can pull the guide plate 411 through its own force, so that the guide plate 411 can drive the upper fan-shaped clamp 41 to reset and move, thereby releasing the clamping on the end of the steel strip. After the adjusting hydraulic cylinder 421 retracts to the desired position, the terminal controller can control the adjusting hydraulic cylinder 421 and the winding drum 2 and the driving hydraulic cylinder 221 to retract synchronously through the set program. This allows the winding drum 2 to move downwards synchronously while the driving inclined block 431 retracts downwards. When the top of the winding drum 2 moves to the same horizontal plane as the top of the rotating disk 21, the obstruction to the horizontal movement trajectory of the steel strip can be released, thereby pushing the hydraulic cylinder 71 to extend and drive the push plate 3. When the push plate 3 pushes the wound steel strip, it can stably move the steel strip to the external conveying track, thus completing the unloading of the wound steel strip.
