Description

Technical Field

[0001] The invention relates to the technical field of spiral loopers, in particular to a steering transition horizontal spiral looper. Background Art

[0002] Horizontal spiral looper is an important equipment in welded pipe and cold-bending production lines. It is a new material storage method that can meet the high-speed and continuous production requirements of welded pipe production lines.

[0003] The horizontal spiral looper is mainly used to temporarily store the strip steel in front of the forming machine. When the operation of coil changing, uncoiling, shearing, welding, etc. is carried out and the feeding into the looper is stopped, the material against the outer cage in the looper is pressed against the inner cage one circle at a time to ensure continuous discharge of the material, so as to ensure the continuous production of the welded pipe unit during the welding of the front and rear coils of strip steel, playing the role of storing and feeding materials and ensuring the continuous operation of the main rolling mill.

[0004] During operation, the feed motor drives the feed rollers, which, through friction, drive the steel strip into the storage hopper. This causes the strip to be wound in opposite directions in the inner and outer storage areas of the hopper. As the strip passes through the inlet channel, it gradually twists from a horizontal position to a vertical position and is loaded into the storage tray. The strip fills the inner and outer rings of the storage tray, forming a coil. When a coil of strip is exhausted, the machine stops, waiting for shearing (heading) and butt welding to be completed before refilling the hopper. Once the strip is butt welded, the looper is filled, causing the strip near the inner cage to expand naturally, gradually, toward the outer cage due to runoff, until it is completely filled.

[0005] After the material is full, make the filling speed equal to the welding pipe speed. By following this cycle, the loop can ensure that the material is continuously supplied to the rolling mill.

[0006] When the strip needs to be led out from the inner ring, it passes through the outlet channel, causing the strip to gradually twist from a vertical state to a horizontal state and enter the forming unit.

[0007] However, most horizontal spiral loopers on the market have limitations. They typically maintain a vertical strip during strip discharge, while feeding the rolling mill typically requires a horizontal strip. Therefore, after the strip exits the horizontal spiral looper, an additional mechanism is required to reverse its direction. This not only takes up workshop space but also complicates the equipment, increasing maintenance and operating costs.

[0008] The Chinese patent document (publication number: CN204074734U, patent name: horizontal spiral looper) discloses a technology comprising an inner and outer bracket, which are coaxially arranged. Spokes are arranged on the outer circumference of the inner bracket, extending radially from the inner bracket to the inner circumference of the outer bracket. Rollers are distributed circumferentially along both the inner and outer brackets, alternating between the rollers and spokes along the circumference of the outer bracket. Several runners are provided on one side of the spokes opposite the rollers. A rotating shaft is fixed on either side of the spokes. The runners are axially fixed to the shaft and can rotate circumferentially about the shaft. A transmission belt is provided between all the runners on one side of the spokes. The belt is in close contact with the runners, and all the runners are contained within a closed space enclosed by the belt. The maximum height of the belt above the ground is greater than the maximum height of the spokes. This horizontal spiral looper utilizes a transmission device on the spokes to convert the sliding friction between the steel belt and spokes into rolling friction between the runners and the belt, reducing mechanical wear while improving the quality of the steel pipe.

[0009] It can be seen from the above patent documents that after the horizontal spiral loop inputs or outputs the steel strip, the steel strip is in a vertical state, which is not conducive to the docking of the steel strip with the next process, thus increasing the cost of moving the steel strip. Summary of the Invention

[0010] The invention overcomes the shortcomings of the prior art and provides a steering transition horizontal spiral loop. The discharging inclined drum mechanism is used to discharge the steel belt from the horizontal spiral loop at an oblique upper direction. The discharging inclined drum mechanism provides a transition channel for the output of the steel belt. Its inclined setting enables the steel belt to transition to the subsequent conveying link more naturally, avoiding the impact and vibration caused by sudden turning or changing the conveying direction, ensuring the smoothness of the steel belt conveying process, reducing damage to the steel belt, and improving the reliability of the entire conveying system. In order to solve the above technical problems, the invention is achieved through the following technical solutions: A steering transition horizontal spiral looper, comprising a spiral buffer assembly, the spiral buffer assembly comprising a spiral outer ring bracket, a rotating cover plate and a central spiral winding structure; The central spiral winding structure includes a central axis body, the central axis body is connected to the central bottom plate, the central bottom plate is connected to the discharging inclined drum mechanism, and a plurality of first rollers are arranged around the periphery of the central bottom plate, and the first rollers are arranged perpendicular to the central bottom plate; The central axis is rotatably connected to the central turntable. The spiral outer ring bracket is provided with an edge retaining frame, which is formed by surrounding a continuous steel material.

At this time, if the steel belts continue to be input into the outer area again, a storage gap will be formed between the inner and outer areas. As the steel belts in the inner area are continuously output, and the rotating cover plate keeps rotating with the steel belts, the steel belts will gradually transition from the outer area through the storage gap to the inner area, so that there are always steel belts in the inner area, so that the spiral loop can continuously convey the steel belts to the equipment.

In the initial state, the flat surface of the steel strips is parallel to the ground. The feed limiter is used to guide the horizontal input of the steel strips. The turning transition section provides space for the steel strips to twist 90 degrees during the conveying process, so that they can turn from a horizontal state to a vertical state. The turning input limiter is used to receive and maintain the vertical state of the steel strips. The brake component is used to brake when the steel bar input needs to stop, and the front and rear limit components are used to correct the left and right deviation of the steel bar to ensure its accurate and centered transportation; so that the steel bar can be smoothly fed into the edge entrance, and the active feeding component is used to provide power for the steel bar; The feeding limiting component includes a horizontal double roller and a vertical double roller.

[0015] Furthermore, the active feeding component includes an active base, the active base is rotatably connected to an active fixed shaft, the active base is slidably connected to an active sliding block, and the active sliding block is connected to the active moving shaft; A shift power component is also provided on one side of the active feeding component, and the output end of the shift power component is connected to the active sliding block; The power linkage box includes a power main shaft, one end of the power main shaft is connected to the pulley, and the other end is connected to the first helical gear, the first helical gear is meshed with the second helical gear, the second helical gear is connected to the first transmission shaft, and the first transmission shaft is connected to the first gear; The first gear is meshed with the second gear, and the second gear is connected to the second transmission shaft; The first transmission shaft is connected to the active movable shaft, and the second transmission shaft is connected to the active fixed shaft.

[0018] Compared with the prior art, the beneficial effects of the invention are: 1. The discharging inclined drum mechanism is used to make the steel belt be discharged from the horizontal spiral loop at an oblique upper direction. The discharging inclined drum mechanism provides a transition channel for the output of the steel belt. Its inclined setting enables the steel belt to transition to the subsequent conveying link more naturally, avoiding the impact and vibration caused by sudden turning or changing the conveying direction, ensuring the stability of the steel belt conveying process, reducing damage to the steel belt, and improving the reliability of the entire conveying system.

[0019] 2. The first roller, surrounding the center baseplate, not only supports the steel strip during transition but also, through its rolling surface, significantly reduces friction during strip movement. The tilting axis of the discharging tilting drum mechanism is manufactured using high-precision bearings and high-quality steel. Its surface has been specially treated for an extremely low coefficient of friction and high wear resistance, reducing resistance between the steel strip and the outer side of the tilting drum, ensuring smoother strip delivery.

[0020] 3. This tilted delivery method makes the steel strip more stable during delivery, reduces the failure rate of the steel strip during delivery, and ensures production continuity. The docking base of the discharging tilting drum mechanism is made of heavy cast iron material. After fine processing and treatment, it has excellent shock absorption performance and stability, ensuring that the entire mechanism will not shake or move during operation, further reducing failures caused by equipment instability. 4. The design of the discharging tilting drum mechanism can reduce damage to the steel strip and reduce the risk of wrinkles or deformation during the discharge process, thus ensuring the quality and integrity of the steel strip. Its tilted discharge method allows the steel strip to transition naturally to subsequent links, avoiding damage to the steel strip caused by forced conveying. 5. The special positioning of the output limiter ensures that the steel strip first wraps around the side of the discharging tilting drum mechanism away from the output limiter before wrapping back to the output limiter. Since the steel strip is delivered at a high speed, this wrapping action before delivery effectively reduces its speed, making delivery smoother and preventing it from flying out during high-speed delivery, thus preventing safety accidents. It also reduces the risk of wrinkling or deformation of the steel strip, thus ensuring its quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION The preferred embodiments of the invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention and are not used to limit the invention.

[0023] like Figures 1 to 14 As shown, a steering transition horizontal spiral looper includes a spiral buffer assembly A, which includes a spiral outer ring bracket 1, a rotating cover plate 2 and a central spiral winding structure 3; The central spiral winding structure 3 includes a central axis 303 connected to a central base plate 305, which in turn connects to the discharging tilting drum mechanism 4, providing a transition path for the steel strip to be discharged. Several first rollers 306 surround the periphery of the central base plate 305, arranged perpendicular to the central base plate 305. These rollers not only support the steel strip during transition, but also, through their rolling surfaces, significantly reduce friction during the movement of the steel strip, ensuring smooth movement.

[0024] The central spiral winding structure 3 is constructed based on a winding base 301, which is provided with a polyhedral column 3011. Radiating support plates 3012 extend from multiple sides of the polyhedral column 3011, providing a stable support for the central turntable 3013, ensuring its smooth operation. A first bearing 302 and a second bearing 304 are mounted within the winding base 301. The central axis 303 is rotatably connected to the winding base 301 via these two bearings. In this embodiment, both the first bearing 302 and the second bearing 304 are roller bearings. Roller bearings employ a roller structure. Compared to ball bearings, their rolling elements and raceways form a linear contact pattern, resulting in a larger contact area. This allows roller bearings to withstand high radial and axial loads, making them suitable for highly loaded rotating bodies. In a central spiral winding structure, the central axis 303 may be subjected to significant radial and axial forces. The high load-bearing capacity of roller bearings ensures that they will not be damaged by excessive loads during long-term operation, thus ensuring the stability and reliability of the equipment. Due to the large rolling contact area of ​​roller bearings, their coefficient of friction is low. This means that during rotation, the roller bearings generate less frictional resistance, effectively reducing mechanical energy consumption and wear. In a central spiral winding structure, the low coefficient of friction ensures smoother rotation of the central axis 303, reduces energy loss, improves equipment efficiency, and extends the bearing's service life.

[0025] The central axis 303 is rotatably connected to the central turntable 3013, allowing the turntable 3013 to rotate flexibly around the central axis 303. The spiral outer ring support 1 is equipped with an edge frame 102, which is formed from a continuous steel ring. This structural design is sturdy and durable, with excellent strength and stability. The use of continuous steel allows the edge frame 102 to withstand significant external impacts, effectively limiting and supporting the incoming steel strip. Several edge rollers 103 are installed inside the edge frame 102. These rollers convert sliding friction between the steel strip and the frame into rolling friction, significantly reducing friction. This not only reduces energy loss and improves conveying efficiency, but also reduces wear on the steel strip surface, ensuring the surface quality of the steel strip. This improves conveying efficiency, reduces operating costs, and enhances the conveying quality of the steel strip.

[0026] An upper stopper 104 is located above the edge inlet 1021. While simple in structure, this block serves a crucial purpose: it effectively prevents the steel strip from overflowing during conveyance. Made of high-strength material, it offers excellent impact resistance. This enhances conveyance safety, preventing potential equipment failures and accidents caused by steel strip overflow.

[0027] The two ends of the steel extend to form parallel edge entrances 1021. The rotating cover 2 is fixedly connected to the middle turntable 3013 and is located between the edge frame 102 and the first roller 306. The rotating cover 2 realizes orderly storage of the steel strip, which is convenient for subsequent output and dynamic balance adjustment. The middle turntable 3013 is connected to the second roller 308. A roller gap is provided on the rotating cover 2. The second roller 308 is embedded in the roller gap. The second roller 308 is located in the inner area E. The second roller 308 is arranged perpendicular to the first roller 306. The second roller 308 makes the lower end face of the steel strip contact with the second roller 308 when the steel strip is running in the inner area E. This makes the steel strip smoother during output, reduces the occurrence of jams and blockages, improves the output performance of the steel strip, and improves the continuity and stability of transportation.

[0028] The storage area is between the middle turntable 3013 and the first roller 306; The spiral outer ring support 1 limits and supports the incoming steel strip. The rotating cover plate 2 drives the steel strip to spirally accumulate within the edge retaining frame 102. The central spiral winding structure 3 guides the inner layer of the steel strip and transfers it to the discharge inclined drum mechanism 4. The discharge inclined drum mechanism 4 discharges the steel strip from the upper storage area at an inclined angle. This tilted discharge method allows the steel strip to transition more smoothly to the subsequent conveying stage. The outer wall of the discharge inclined drum mechanism 4 is smooth and has excellent wear and corrosion resistance. This reduces damage to the steel strip and improves conveying quality and efficiency. This advantage is that it ensures a smooth transition of the steel strip, reduces damage to the steel strip, and improves the reliability of the entire conveying system.

[0029] The upper ends of several first rollers 306 are connected to a fixed upper ring 307, ensuring that the fixed upper ring 307 remains fixed in position during operation. This connection effectively enhances the overall structural rigidity of the first rollers 306, reduces shaking and displacement caused by vibration and external forces, improves the reliability and durability of the equipment, and extends the service life of the first rollers 306.

[0030] The radial support plates 3012 are interconnected with the radial support structure 101, while the end of the radial support structure 101 facing away from the radial support plates 3012 is connected to the inner side of the edge guard frame 102. The radial support plates 3012 are designed in a radial pattern and evenly distributed around the center turntable 3013, effectively distributing the pressure from the center turntable 3013. Made of lightweight yet high-strength composite materials, they ensure support strength while reducing their own weight, thereby lowering the overall load on the equipment. The radial support structure 101 acts like a bridge, tightly connecting the radial support plates 3012 and the edge guard frame 102 to form a stable support system. This structural design enhances the stability and balance of the entire spiral loop structure, allowing the equipment to withstand greater loads during operation, improving its load-bearing capacity and resistance to deformation. It also effectively reduces noise and energy loss caused by vibration and impact, thereby improving equipment efficiency.

[0031] The discharging tilting drum mechanism 4 consists of a docking base 401, a tilting axis 402, and a tilting cylinder 403. The docking base 401 is constructed of heavy cast iron and meticulously machined and treated for excellent shock absorption and stability. It provides a solid foundation for the entire discharging tilting drum mechanism 4, ensuring it remains stable and free of vibration and displacement during operation. The tilting axis 402 is constructed of high-precision bearings and high-quality steel, with a specially treated surface for extremely low friction and high wear resistance. It rotates flexibly, reducing resistance between the steel strip and the outer surface of the tilting cylinder 403 as it wraps around it for delivery, ensuring smoother delivery. The tilting cylinder 403's tilt allows the steel strip to be delivered outwards along its angled orientation. This design allows the steel strip to transition naturally to subsequent conveying stages, minimizing damage. The discharging tilting drum mechanism 4 ensures smooth steel strip delivery, improving conveying efficiency while also reducing the risk of strip failure during delivery, ensuring continuous production.

[0032] The fixed upper ring 307 is connected to the output limiting component 5, and the output limiting component 5 is located on the side where the discharging tilting cylinder mechanism 4 intersects the rotating cover plate 2 at an obtuse angle; the output limiting component 5 includes an output seat body 501, and the lower end of the output seat body 501 is connected to the output auxiliary bottom cylinder 503. The output auxiliary bottom cylinder 503 is provided with output limiting side cylinders 502 at both ends. The output auxiliary bottom cylinder 503 can guide the steel belt to pass through the output limiting component 5 smoothly, reduce the resistance of the steel belt during transmission, and improve transmission efficiency. The output limiting side cylinder 502 is also provided with an output upper limit block at the end away from the output auxiliary bottom cylinder 503. After the steel belt wraps around the discharging tilting cylinder mechanism 4, it is pulled toward the output limiting component 5 and pulled out from between the two output limiting side cylinders 502. The two output limiting side cylinders 502 limit the left and right sides of the steel belt, preventing the steel belt from deviating left and right during operation, thereby ensuring the linearity and stability of the steel belt transmission. The output upper limit block can accurately limit the upward displacement of the steel belt, and cooperates with the output auxiliary bottom cylinder 503 to fully limit the upper and lower ends of the steel belt, ensuring that the steel belt always runs within the specified range.

[0033] The output limiting component 5 is located on the side where the discharging inclined cylinder mechanism 4 and the rotating cover plate 2 intersect at an obtuse angle; in this way, the steel belt first goes around to the side of the discharging inclined cylinder mechanism 4 away from the output limiting component 5 when being output, and then goes around back to the output limiting component 5. Because the speed of the steel belt is relatively fast during the output process, the output after such wrapping can effectively reduce the speed of the steel belt movement, making the output of the steel belt more gentle, preventing the steel belt from flying out during high-speed output, thereby preventing the occurrence of safety accidents, and such a smooth transition can also reduce the risk of wrinkles or deformation of the steel belt during the output process, thereby ensuring the quality and integrity of the steel belt.

[0034] The portion of the middle turntable 3013 near the edge frame 102 is the outer area D of the storage area, and the portion of the middle turntable 3013 near the first roller 306 is the inner area E of the storage area; During the steel strip input stage, the steel strip is input from the edge inlet 1021. As the rotating cover 2 rotates, the steel strip is accumulated in an annular shape in the outer zone D. The input steel strip gradually accumulates along the edge baffle 102 of the outer zone D, so that the accumulated steel strip gradually extends to the inner zone E until the upper surface of the rotating cover 2 is completely covered. During the steel strip output stage, the steel strip is first fed into the gap between the first rollers 306 at one end of the rotating cover plate 2, and then flows around the discharging inclined drum mechanism 4 and is output from the upper side of the spiral outer ring support 1. During the dynamic balance stage of steel belt conveying, the steel belts accumulated on the rotating cover plate 2 gradually move to the inner zone E, making the outer zone D gradually empty. At this time, if the steel belts continue to be input into the outer zone D again, storage gaps will be formed between the inner zone E and the outer zone D. As the steel belts in the inner zone E are continuously output and the rotating cover plate 2 keeps rotating with the steel belts, the steel belts will gradually transition from the outer zone D through the storage gap to the inner zone E, so that there are always steel belts in the inner zone E, so that the spiral loop can continuously convey the steel belts to the equipment.

[0035] A feeding assembly B is provided on one side of the edge entrance 1021, and the feeding assembly B includes a feed limit component 6, a steering transition section 7, a steering input limit component 8, a brake component 9, a front and rear limit component 10 for correcting deviation, and an active feeding component 11; The feed limiting component 6 is used to connect the ends of the coiled steel bars. The feed limiting component 6 includes a horizontal double roller 601 and a vertical double roller 602. The horizontal double roller 601 and the vertical double roller 602 limit and guide the steel bars from different directions to ensure that the steel bars maintain a stable horizontal state when entering the system. In the initial state, the flat surface of the steel bar is parallel to the ground. The feed limiting component 6 is used to guide the horizontal input of the steel bars. The steering transition section 7 provides a twisting space for twisting the steel bars 90° during the transportation process. The steering transition section 7 is provided with sufficient length so that the steel strip will not be damaged when twisted 90°, so that it can be turned from a horizontal state to a vertical state; the steering input limiting component 8 is used to receive and maintain the vertical state of the steel bar; it ensures the consistency and stability of the state of the steel bar when entering the next link, which is conducive to the smooth progress of subsequent operations and improves the reliability of the entire transportation system. The brake component 9 is used for braking when the steel bar input needs to stop. The brake component 9 includes a first brake seat body 901 and a second brake seat body 902 that are relatively arranged; the first brake seat body 901 is connected to the brake power component 903. In this embodiment, the brake power component 903 is a cylinder or a hydraulic cylinder, and the output end of the brake power component 903 is connected to the brake push block 904; a brake clamping block 9021 is provided on the second brake seat body 902. In this embodiment, the brake push block 904 and the brake clamping block 9021 are made of rubber. When the steel bar input needs to stop, the brake power component 903 drives the brake push block 904 to move toward the brake clamping block 9021, thereby clamping and braking the steel bar.

[0036] The front and rear limiting components 10 for correcting the left and right deviations of the steel bars are used to ensure that they are accurately centered during transportation. This allows the steel bars to be smoothly fed into the edge entrance 1021. Both sides of the active feeding component 11 are provided with front and rear limiting components 10 for correcting the left and right deviations. The front and rear limiting components 10 for correcting the left and right deviations of the steel bars are provided with upper limiting rollers 1001 for correcting the right and left deviations and side limiting rollers 1002 provided on both sides of the upper limiting rollers 1001 for correcting the right and left deviations of the steel bars. The upper limiting rollers 1001 for correcting the right and left deviations and the side limiting rollers 1002 for correcting the right and left deviations of the steel bars are used to correct the left and right deviations of the steel bars. When the steel bars deviate from the left and right deviations, these limiting rollers can adjust the position of the steel bars in time. The front and rear limiting components 10 for correcting the right and left deviations effectively improve the accuracy of steel bar transportation, reduce equipment damage or transportation failures that may be caused by steel bar deviation, and improve the operating efficiency and stability of the entire system.

[0037] The active feeding component 11 is used to provide power for the steel bars; the active feeding component 11 includes an active base 1101, which is rotatably connected to an active fixed shaft 1102, and an active sliding block 1103 is slidably connected to the active base 1101, and the active sliding block 1103 is connected to the active movable shaft 1104; an offset power component 1105 is also provided on one side of the active feeding component 11, and the output end of the offset power component 1105 is connected to the active sliding block 1103; The power linkage box 1106 includes a power main shaft 1161, one end of which is connected to a pulley 1162 and the other end to a first bevel gear 1163. The first bevel gear 1163 meshes with a second bevel gear 1166, which in turn meshes with a first transmission shaft 1164, which in turn meshes with a first gear 1167. The first gear 1167 meshes with a second gear 1168, which in turn meshes with a second transmission shaft 1165. The first transmission shaft 1164 is connected to the active movable shaft 1104, and the second transmission shaft 1165 is connected to the active fixed shaft 1102. The active feeding component 11 provides power for the steel bars, pushing them through the system. Power is transmitted to the external motor via the pulley 1162 and then to the power main shaft 1161. Through a series of gear transmissions, the power is transmitted to the active fixed shaft 1102 and the active movable shaft 1104, thereby driving the steel bars forward. The offset power unit 1105 drives the active sliding block 1103 to slide, adjusting the position of the active moving shaft 1104 to accommodate different conveying requirements. The active feeding unit 11 provides stable and reliable power support for the conveying of steel strips. Its adjustable structural design allows it to accommodate steel strips of varying specifications and conditions, enhancing the system's flexibility and versatility.

[0038] After being output from the discharging tilting drum mechanism 4, the steel strip is brought into the output assembly C. The output assembly C includes an output upper and lower positioning seat C1, which is rotatably connected to a number of output upper and lower positioning rollers C11. The output upper and lower positioning rollers C11 are used to define the upper and lower positions of the flat surface of the steel strip. During the steel strip conveying process, the steel strip may be offset in the vertical direction due to various factors. The output upper and lower positioning rollers C11 can constrain and adjust the steel strip in real time to ensure that the steel strip always remains within the appropriate upper and lower position range. Through this precise positioning, vertical shaking and movement of the steel strip are avoided, ensuring the stability and accuracy of the steel strip conveying, and providing a good foundation for subsequent processing or use. At the same time, the design of the rotating connection allows the output upper and lower positioning rollers C11 to rotate flexibly with the movement of the steel strip, reducing friction between the steel strip and the output upper and lower positioning rollers C11 and further protecting the surface of the steel strip.

[0039] One side of the output upper and lower positioning seats C1 is connected to the output lateral positioning seat C2, and the output lateral positioning seat C2 is connected to two output lateral positioning rollers C21. The distance between the two output lateral positioning rollers C21 is adjustable, and the two output lateral positioning rollers C21 are used to limit the left and right position of the steel belt. During the actual conveying process, the steel belt may deviate to the left and right due to vibration of the conveying equipment, uneven tension, etc. The output lateral positioning rollers C21 can timely restrain the steel belt laterally to prevent it from deviating from the predetermined conveying path. More importantly, the distance between the two output lateral positioning rollers C21 is adjustable. This adjustable design allows the output component C to adapt to steel belts of different widths. When it is necessary to convey steel belts of different specifications, it is only necessary to adjust the distance between the two output lateral positioning rollers C21 to achieve precise positioning and guiding of steel belts of different widths, greatly improving the versatility and applicability of the output component C.

[0040] The present invention utilizes the discharging inclined drum mechanism 4 to discharge the steel strip from the horizontal spiral loop at an oblique upper direction. The discharging inclined drum mechanism 4 provides a transition channel for the output of the steel strip. Its inclined setting enables the steel strip to transition to the subsequent conveying link more naturally, avoiding the impact and vibration caused by sudden turning or changing the conveying direction, ensuring the stability of the steel strip conveying process, reducing damage to the steel strip, and improving the reliability of the entire conveying system.

[0041] The first roller 306, surrounding the central base plate 305, not only supports the steel strip during transition but also, through its rolling surface, significantly reduces friction during the strip's movement. The tilting axis 402 of the discharging tilting drum mechanism 4 is manufactured using high-precision bearings and high-quality steel. Its surface has been specially treated to achieve an extremely low coefficient of friction and high wear resistance. This reduces resistance between the steel strip and the outer side of the tilting drum 403, ensuring smoother strip delivery.

[0042] This tilted delivery method makes the steel strip more stable during delivery, reduces the failure rate during delivery, and ensures continuous production. The docking base 401 of the discharging tilting drum mechanism 4 is made of heavy cast iron and has been carefully processed and treated to provide excellent shock absorption and stability, ensuring that the entire mechanism will not shake or move during operation, further reducing failures caused by equipment instability. The design of the discharging tilting drum mechanism 4 reduces damage to the steel strip, lowering the risk of wrinkles or deformation during delivery, thereby ensuring the quality and integrity of the steel strip. Its tilted delivery method allows the steel strip to transition naturally to subsequent stages, avoiding damage to the steel strip caused by forced conveying. The special positioning of the output limiter 5 ensures that the steel strip, during delivery, first wraps around the side of the discharging tilting drum mechanism 4 away from the output limiter 5 before wrapping back around to the output limiter 5. Since the steel strip is delivered at a relatively high speed, this wrapping before delivery effectively reduces its speed, making delivery smoother and preventing it from flying out during high-speed delivery, thus preventing safety accidents. It also reduces the risk of wrinkling or deformation of the steel strip, thus ensuring its quality.
