Description

Technical Field

[0001] The present invention relates to the technical field of steel strip production, and in particular to an off-line leveling system for steel coils. Background Art

[0002] After cold rolling, the stainless steel strip undergoes annealing and pickling to further improve its machinability and surface quality. The strip then passes through a leveling mill and a straightening unit to improve its shape, ensuring better straightness for downstream customers during slitting and flattening. Finally, the strip is wound and packaged into coils. To prevent scratches on the surface, paper padding is placed between each layer of the coil to protect the surface from scratches. After quality inspection, some finished coils fail to meet quality requirements and become defective. To reduce the economic losses caused by defective products, companies use offline coil leveling systems to repair these defective products. This allows them to meet the required shape requirements after further leveling and shaping, becoming qualified products.

[0003] The existing offline leveling system for steel coils has the following shortcomings:

[0004] 1. Before trimming the steel strip, the paper padding on the strip surface needs to be removed. After the uncoiler unwinds the steel coil into a steel strip, it is supported and guided by the steel strip support mechanism for horizontal transmission. An air blowing mechanism is installed at the entrance of the leveling mechanism to blow the paper padding away from the leveling mechanism to prevent it from entering the leveling mechanism. Workers need to grab the paper padding from the steel strip support mechanism and place it in a recycling bin. Due to the limited space in the recycling bin and the chaotic placement of the paper padding, the recycling bin can be filled with paper padding equivalent to the length of several steel coils, requiring workers to frequently carry and empty the recycling bin, adding to their workload. Furthermore, when the steel strip is unwound, the paper padding needs to be manually retrieved simultaneously, which is labor-intensive and inconvenient for workers to handle other control tasks.

[0005] 2. During the steel strip leveling process, foreign matter such as dust and wool felt fibers will be present on the surface of the steel strip. In the subsequent production process, these foreign matter on the surface of the steel strip will adhere to the roller after coming into contact with the surface of the roller on the leveling mechanism. Since the equipment is always running at high speed, although some foreign matter will be taken away by the steel strip, some foreign matter will still adhere to the roller and be continuously and equidistantly transferred to the surface of the steel strip, causing defects on the surface of the steel strip and resulting in a decrease in the quality of the steel strip. Therefore, it is necessary to clean the rollers on the leveling mechanism regularly, but the roller assembly of the existing leveling mechanism cannot be moved. The staff needs to shut down the machine and enter the steel coil offline leveling system for maintenance and cleaning. Due to the numerous mechanisms and narrow space around the leveling mechanism, it is difficult for the staff to carry out the cleaning work, resulting in low work efficiency and even some blind spots that cannot be cleaned in place.

[0006] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

DETAILED DESCRIPTION

[0033] The present invention provides an offline steel coil leveling system. To clarify the objectives, technical solutions, and effects of the present invention, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit its scope.

[0034] In this article, “before” means Figure 1 The direction indicated by the arrow in the middle is opposite to that of “front”.

[0035] See also Figure 1The present invention provides a steel coil offline leveling system, comprising a paper winding mechanism 1, an unwinder 2, a steel strip holding mechanism 3, a leveling mechanism 4, a paper padding machine 5 and a rewinding machine 6 arranged in sequence; the paper winding mechanism 1 is used to recycle the padding paper 101 and rewind it into a paper roll 10; a gluing mechanism 7 for automatically sticking double-sided tape 703 on the paper roll 10 is provided above the paper winding mechanism 1; the steel strip holding mechanism 3 is used to support and guide the steel strip 211 to be transported horizontally, and is located at the steel The padding paper 101 on the belt supporting mechanism 3 is transported to the front of the paper winding mechanism 1 through the transporting device; the uncoiler 2 is used to unfold the steel coil 21 into a steel strip 211 and drive the steel strip 211 to be transported toward the leveling mechanism 4; the steel strip supporting mechanism 3 is used to support and guide the steel strip 211 for horizontal transportation; the leveling mechanism 4 is used to straighten and level the steel strip 211; the paper padding machine 5 is used to lay new padding paper on the steel strip 211; the winder 6 is used to wind the steel strip into a steel coil.

[0036] During operation, the steel coil to be refurbished is transported by a transport trolley in the pit 23 to the unwinding roller 25 of the uncoiler 2. The transport trolley then leaves the uncoiler, and the support plate 31 on the steel strip supporting mechanism 3 moves toward the steel coil until it rests on the steel strip. The unwinding roller first drives the steel coil to rotate in the opposite direction, causing the free end of the steel strip to move above the support plate 31. Then, the unwinding roller 25 moves forward, unwinding the steel coil 21 and supporting the steel strip 211 toward the leveling mechanism 4. At this time, when the free end of the steel strip moves to the set position, the uncoiler 2 stops. At this time, there is a section of steel belt 211 on the support plate 31, and a piece of padding paper 101 is laid on the upper surface of the steel belt 211. The conveying device sucks up the free end of the padding paper, and then conveys the padding paper 101 to the front of the paper winding mechanism 1; at the same time, the gluing mechanism 7 automatically sticks a section of double-sided tape extending axially along the paper roll 10 on the paper roll 10 of the paper winding mechanism. The staff standing next to the paper winding mechanism 1 removes the padding paper on the conveying mechanism and manually sticks the padding paper neatly on the paper roll 10. The unwinder 2 and the paper winding mechanism 1 move synchronously, and the unwound padding paper 82 is automatically wound around the paper roll to realize the automatic recycling of the padding paper, and the steel belt 211 is conveyed to the leveling mechanism 4. After being leveled and shaped by the leveling mechanism 4, the steel belt 211 meets the plate quality. Finally, the padding machine 5 lays the new padding paper on the steel belt 211, and then passes through the winder to wind the steel belt into a steel roll.

[0037] Here, see Figure 1 As shown, the steel strip supporting mechanism 3 includes a support plate 31 and a support plate driving mechanism 32 for driving the support plate to move horizontally. The uncoiler 2 is stopped, specifically by manually controlling the unwinder to stop or by using a sensor set on the support plate 31 to sense whether the free end of the steel strip moves to the set position. The sensor feeds back a signal to the control center, and the control center automatically controls the uncoiler 2 to stop.

[0038] It should be understood that the structures and working principles of the uncoiler 2, paper padding machine 5, steel strip supporting mechanism 3 and winder 6 are all existing technologies and are not the inventive point of the present invention, so they will not be elaborated in this article.

[0039] For details, please refer to Figure 1 and Figure 2 The handling device includes a paper suction mechanism 8 and a transfer mechanism 9 for driving the paper suction mechanism 8 to move. The paper suction mechanism 8 includes a support plate 81, a paper suction cylinder 82 vertically downwardly arranged on the support plate 81, a mounting plate 83 arranged on the end of the piston rod of the paper suction cylinder 82, and a plurality of suction cups 84 arranged on the mounting plate 83. The support plate 81 and the mounting plate 83 extend along the width direction of the steel belt, and one end of the support plate 81 is fixed to the movable support seat 92. In actual application, the suction cup 84 is connected to the vacuum generator through an air pipe. The piston rod of the paper suction cylinder 82 extends, driving the mounting plate 83 and the suction cup 84 to move vertically downward, so that the suction cup 84 is pressed against the pad paper 101. The suction cup 84 uses the effect of vacuum negative pressure to suck the pad paper 101. Finally, the piston rod of the paper suction cylinder 82 retracts to achieve the purpose of sucking up the pad paper 101.

[0040] Furthermore, two guide rods 85 are provided on the mounting plate 83, and a sliding sleeve 86 is fixedly provided on the support plate 81, positioned opposite to the guide rods 85. The two guide rods 85 are slidably inserted into the sliding sleeve 86. The guiding action of the sliding sleeve 86 and the guide rod 85 ensures the correct movement direction of the mounting plate 83 and protects the piston rod of the paper suction cylinder 82 from shearing forces, thereby preventing the piston rod from deforming due to shearing forces.

[0041] For further information, see Figure 2 The transfer mechanism 9 includes a track 91 arranged next to the steel belt supporting mechanism 3 and extending toward the paper winding mechanism 1, a movable support seat 92 arranged on the track 91, and a support seat driving mechanism 93 for driving the movable support seat 92 to move along the guide direction of the track 91. One end of the support plate 81 is fixedly set on the movable support seat 92.

[0042] For further information, see Figure 2The track 91 is constructed from multiple rack segments and suspended by a stand 911, allowing the paper suction mechanism 8 to avoid the steel coil 21 during movement, allowing it to pass over the steel coil 21. The movable support 92 includes a base 921, a first gear 922 rotatably mounted on the base 921, side rollers 923, and a bottom roller 924. The first gear 922 meshes with the rack, the side rollers 923 press against the sides of the rack, and the bottom roller 924 presses against the bottom surface of the rack. The combined positioning of the first gear 922, side rollers 923, and bottom rollers 924 allows the movable support 92 to move smoothly and steadily along the track 91 without deviating from the track 91.

[0043] Preferably, see Figure 2 The support seat driving mechanism 93 includes a transfer motor 931 fixed on the seat body 921, a second gear 932, and a third gear 933 engaged with the second gear 932 for transmission; the second gear 932 is mounted on the main shaft of the transfer motor 931, and the first gear 922 is rotatably connected to the seat body 921 through a rotating shaft, one end of the rotating shaft is mounted with the first gear 922, and the other end is mounted with the third gear 933; that is, the transfer motor 931 rotates through the transmission of the second gear 932 and the third gear 933, driving the first gear 922 to rotate. Due to the high stability of the gear transmission, the first gear 922 can rotate smoothly.

[0044] Preferably, see Figure 1 Limit stops 94 are provided at both ends of the track 91. Each limit stop 94 is equipped with an in-position sensor 95. The base 921 is provided with a trigger plate 96 that triggers the in-position sensor 95. When the in-position sensor 95 senses the trigger plate 96, it indicates that the movable support base 92 has moved into position. The in-position sensor 95 then sends a feedback signal to the control center, causing the transfer motor 931 to stop. Even if the in-position sensor 95 malfunctions, the limit stops 94 can still block the movable support base 92, preventing the movable support base 92 from deviating from the track 91 and causing damage to the paper suction mechanism 8.

[0045] For details, please refer to Figure 3The paper winding mechanism 1 comprises a paper winding frame 11, a reel 12 mounted horizontally on the reel frame 11, a guide roller 13, a motor support 14 mounted on the reel frame 11, and a paper winding motor 15 mounted on the motor support 14. The guide roller 13 is located downstream of the reel 12. The ends of the reel 12 are fixed to the reel frame 11 via bearing blocks 16. The paper winding motor 15 is in transmission connection with the reel 12. The guide roller 13 guides the reel 12, ensuring that the backing paper is more easily wound onto the reel 12. The bearing blocks 16 are provided with upward-opening U-shaped slots 17. A bearing 18 is provided at each end of the reel 12, and each bearing 18 is inserted into a corresponding U-shaped slot 17. When placing the reel 12, the bearings can be placed directly through the opening of the U-shaped slot 17, which is convenient and quick. The U-shaped slot 17 is deep enough to prevent the reel 12 from falling during operation. After the padding paper is pasted on the reel 12 with double-sided tape, the winding motor drives the reel 12 to rotate, and the padding paper is neatly wound on the reel 12 to form a paper roll. The padding paper recovery action is carried out synchronously with the unwinding of the steel coil until the unwinding of the steel coil is completed, thereby achieving the effect of automatic padding paper recovery; the staff can take care of other work at the same time, improve work efficiency and reduce labor intensity.

[0046] For details, please refer to Figure 4 The gluing mechanism 7 includes a gluing head 71, two vertical beams 721 relatively arranged on the paper reel frame 11, a horizontal beam 722 arranged between the two vertical beams 721, a sliding beam 723 slidably arranged on the two vertical beams 721, a gluing head 71 slidably arranged on the sliding beam 723, a vertical movement force module 73 for driving the sliding beam 723 to move vertically relative to the frame, and a horizontal movement force module 74 for driving the gluing head 71 to move axially along the reel 12.

[0047] When applying glue, the vertical moving force module 73 drives the sliding beam 723 and the glue head 71 set on the sliding beam 723 to descend, so that the glue head 71 is pressed on the outer peripheral surface of the reel 12, and the reel 12 applies a reaction force to the glue head 71, and feeds back to the vertical moving force module 73, so that the output torque of the vertical moving force module 73 changes, thereby judging that the glue head 71 has moved into place. Then the gluing head 71 moves to stick one end of the double-sided tape on the reel 12, and then the transverse moving force module 74 drives the gluing head 71 to move axially along the reel 12, so that a section of double-sided tape 703 extending along its axial direction is attached to the reel 12. Finally, under the pull of the transverse moving force module 74, the gluing head 71 is disconnected from the double-sided tape 703 on the reel 12 and reset to the initial position, realizing automatic gluing, which greatly shortens the gluing working time. The staff only needs to press the padding paper on the double-sided tape 703 to complete the connection between the padding paper and the reel 12. It should be noted that the reel 12 will become a paper roll 10 after the padding paper is wound up. The gluing mechanism 7 sticks the double-sided tape on the paper roll 10 in the above manner. When the diameter of the paper roll 10 has reached the set size, the staff can quickly replace the reel 12 on site without affecting normal production, and the labor intensity of the staff is low.

[0048] In this embodiment, the vertical moving force module 73 includes a torque motor arranged at the top of the vertical beam 721, a first screw rod vertically arranged on the vertical beam 721, a first screw nut arranged on the screw rod, and the first screw nut is fixedly connected to the sliding beam 723; the torque motor is transmission-connected to the first screw rod. The torque motor drives the first screw rod to rotate, thereby driving the first screw nut, the sliding beam 723 and the components arranged on the sliding beam 723 to move vertically. The torque motor can continue to operate when the rotor is at a low speed or even blocked (that is, the rotor cannot rotate) without causing damage to the motor. When the gluing head 71 presses the paper roll, the torque motor is subjected to resistance, causing its torque to change. Since the control center dynamically detects the torque of the torque motor, when the torque of the torque motor reaches a preset value, an in-position signal is generated, and the control center then controls the torque motor to stop working.

[0049] In this embodiment, the transverse movement force module 74 includes a glue motor arranged at one end of the sliding beam 723, a second screw rod arranged transversely on the sliding beam 723, a second screw nut arranged on the second screw rod, and a transverse slider slidably arranged on the sliding beam 723, and the second screw nut is fixedly connected to the transverse slider; the glue head 71 is fixedly set on the transverse slider, and the glue motor drives the second screw rod to rotate, thereby driving the second screw nut, the transverse slider and the glue head 71 arranged on the transverse slider to move laterally.

[0050] The adhesive applicator 71 includes a housing 751, a bracket 752 disposed within the housing, a tape-releasing mechanism 76 disposed on the housing 751, a waste collection mechanism 77, a brake mechanism 78, a rotatable pressure roller 791 disposed below the tape-releasing mechanism 76 and the waste collection mechanism 77, and a lift cylinder 792 for driving the pressure roller up and down. The waste collection mechanism 77 is used to retract the isolation tape 701, and the brake mechanism 78 is used to limit the rotation of the double-sided tape 702, thereby stopping the unwinding of the double-sided tape 702. It should be understood that the double-sided tape 702 sequentially winds around the pressure roller 791 and the waste collection mechanism 77. When the pressure roller 791 presses against the top of the paper roll 10, a glue line 704 is formed. This glue line can also be understood as a dividing line. The isolation tape between the glue line and the double-sided tape has double-sided tape 703, while the separation tape between the glue line and the waste collection mechanism does not have double-sided tape 703.

[0051] When gluing, the lifting cylinder 792 drives the pressing wheel 791 to descend, so that the pressing wheel 791 is pressed against the outer peripheral surface of the paper roll 10. At the same time, the double-sided tape 702 is pulled by the pressing wheel 791 to unwind. At this time, the double-sided tape 703 located at the fixed glue line 704 is attached to the paper roll 10, and then the transverse moving force module 74 and the waste collecting mechanism 77 act simultaneously to pull the double-sided tape 702 to enable the tape unwinding mechanism 76 to unwind. The double-sided tape 703 on the paper roll 10 is extended along the axial direction of the paper roll 10 as the gluing head 71 moves transversely. When the adhesive length reaches a preset length, the brake mechanism 78 applies a brake to the double-sided tape 702, restricting its rotation and stopping its unwinding. Simultaneously, the waste collection mechanism 77 stops rewinding the isolation tape 701. The double-sided tape 703, pulled by the lateral force module 74, breaks at the fixed glue line 704. Finally, the lifting cylinder 792 drives the pressure roller 791 upward and away from the paper roll 10, completing the gluing operation of the gluing mechanism 7. This achieves a high degree of automation, improves gluing efficiency, and significantly reduces manual labor. Since the free end of the double-sided tape 702 is positioned at the fixed glue line 704 after each gluing operation, the operating consistency and reliability of the gluing mechanism 7 are ensured.

[0052] Furthermore, the braking mechanism 78 includes a stop block 781, an arm 782 fixed to the bracket 752, and a brake cylinder 783 mounted on top of the arm. The output end of the brake cylinder 783 is connected to the stop block 781 via a connecting block 784. Specifically, the brake cylinder 783 drives the stop block 771 to press against the double-sided tape 702, causing it to stop immediately and remain stationary. It should be understood that the friction between the stop block 781 and the double-sided tape 702 is greater than the breaking force of the double-sided tape 703, ensuring that the double-sided tape 703 can be smoothly severed.

[0053] Preferably, the tape unwinding mechanism 76 includes a rewinding wheel 761 rotatably mounted on a bracket 752 and a rotation damper (not visible in the figure) fixedly mounted on the bracket 752. One end of the rewinding wheel 761 is connected to the rotation damper. The double-sided tape 702 is wound around the rewinding wheel 761. This arrangement creates tension in the spacer tape 701 between the tape unwinding mechanism 76, the pressure wheel 791, and the waste collection mechanism 77. Because the traction force exerted by the transverse force module 74 on the double-sided tape 703 is greater than the resistance of the rotation damper, the rewinding wheel 761 can rotate to unwind the tape.

[0054] Preferably, the waste collection mechanism 77 includes a winding disk 771 rotatably arranged on a bracket, a winding roller 772 concentrically arranged with the winding disk 771, and a winding motor (not visible in the figure) fixed on the bracket 752. When working, the winding motor drives the winding disk 771 to rotate, so that the isolation belt is wound on the winding roller 722.

[0055] For details, see Figure 5 As shown, the leveling mechanism 4 includes a leveling frame 41, a lower roller assembly 42, an upper roller assembly 43 arranged above the lower roller assembly 42, a locking mechanism 44 for fixing the upper roller assembly 43 and the lower roller assembly 42, and a pushing mechanism; at least two guide rails 461 perpendicular to the steel strip transmission direction are provided on the ground, and the lower roller assembly 42 is connected to the guide rails 461 through guide wheels 462; the pushing mechanism is used to drive the lower roller assembly 42 and the upper roller assembly 43 to enter or leave the interior of the frame, the lower roller assembly 42 includes a lower roller 421 and a lower receiving seat 422 arranged at both ends of the lower roller 421, and the lower roller 421 is driven to rotate by a first roller driving mechanism 47; the upper roller assembly 43 includes an upper roller 431 and an upper receiving seat 432 arranged at both ends of the upper roller 431, and the upper roller 431 is driven to rotate by a second roller driving mechanism 48.

[0056] In this embodiment, the locking mechanism 44 is provided on the leveling machine frame and is separate from the roll assembly and the lower roll assembly 42, facilitating synchronous movement of the upper roll assembly 43 and the lower roll assembly 42. The upper receiving seat 432 abuts against the lower receiving seat 422, the upper roll 431 is provided above the lower roll 421, and the guide wheel 462 is mounted on the lower receiving seat 422.

[0057] During the leveling process of the steel strip, the upper roller assembly 43 and the lower roller assembly 42 are located inside the leveling frame 41, and the upper roller assembly 43 is pressed against the lower roller assembly 42. The first roller drive mechanism 47 and the second roller drive mechanism 48 correspondingly drive the lower roller 421 and the upper roller 431 to rotate. The locking mechanism 44 tightly connects the upper roller assembly 43 and the lower roller assembly 42 to prevent the upper roller assembly 43 from shaking or detaching from the lower roller assembly 42 during operation, ensuring that the upper roller assembly 43 and the lower roller assembly 42 are tightly combined. The steel strip 211 enters from the entrance of the leveling frame 41, and after being rolled by the upper roller 431 and the lower roller 421, the plate shape of the steel strip 211 is leveled to ensure that the steel strip meets the quality requirements.

[0058] When the leveling mechanism 4 reaches the specified working time, the steel coil offline leveling system will stop and then clean and maintain the upper roller 431 and the lower roller 421. At this time, the locking mechanism 44 releases the lock on the upper roller assembly 43 and the lower roller assembly 42, and the pushing mechanism moves the lower roller assembly 42 and the upper roller assembly 43 from the inside of the leveling frame 41 to the outside of the leveling frame 41 (i.e. Figure 5 In the direction indicated by the middle arrow), the staff has sufficient working space to clean the surface of the upper roller 431 and the lower roller 421. Each part of the roller surface can be cleaned in place, thereby improving the cleaning efficiency and cleaning effect. After the cleaning is completed, the pushing mechanism returns the upper roller assembly 43 and the lower roller assembly 42 to the leveling machine frame 41, so that the steel coil offline leveling system can resume production.

[0059] For further information, see Figure 5 As shown, the pushing mechanism includes a fixed seat and a pushing cylinder 451 , the cylinder body of the pushing cylinder 451 is hinged to the fixed seat, and the end of the piston rod of the pushing cylinder 451 is connected to the bottom of the lower receiving seat 422 .

[0060] For details, see Figure 6-8As shown, the locking mechanism 44 includes a mounting base 441 provided on the leveling frame 41, a swing frame 442 rotatably provided on the mounting base 441, a swing cylinder 443 for driving the swing frame 442 to swing, and a locking rod 444 vertically provided on the swing frame 442; the upper receiving seat 432 is fixedly connected to an upper connecting seat 445, and the lower receiving seat 422 is fixedly connected to a lower connecting seat 446, each of the upper connecting seats 445 has upper slots 447 on both sides, and each of the lower connecting seats 446 has lower slots 448 on both sides. , so that at least 4 sets of locking mechanisms 44 are required to lock the upper roller assembly 43 and the lower roller assembly 42, each of the locking rods 444 includes an upper clamping section 4441, a connecting section 4442, and a lower clamping section 4443 connected in sequence from top to bottom, the connecting section 4442 is fixedly connected to the swing frame 442, the upper clamping section 4441 and the lower clamping section 4443 are symmetrically arranged, and they both include a vertical rod 4445 and top blocks 4444 arranged at both ends of the vertical rod 4445, and the cross-sectional area of the top block 4444 is larger than the cross-sectional area of the vertical rod 4445. When locked, the swing cylinder 443 drives the swing frame 442 to swing, causing the vertical rod 4445 on the upper engaging section 4441 to slide into the corresponding upper engaging groove 447, and the top blocks 4444 at both ends of the vertical rod 4445 to clamp the upper connecting seat 445. Similarly, the vertical rod 4445 on the lower engaging section 4443 slides into the corresponding lower engaging groove 448, and the top blocks 4444 at both ends of the vertical rod 4445 clamp the lower connecting seat 446. After locking, the upper roller 431 and the lower roller 421 are prevented from moving due to external forces during operation, and the upper roller 431 and the lower roller 421 are always kept horizontal, ensuring a smoothing effect.

[0061] In this embodiment, see Figure 9 As shown, the first roller drive mechanism 47 includes a first motor support 471, a first drive motor 472 mounted on the first motor support 471, a first connecting seat 473, and a first transmission shaft 474 rotatably mounted on the first connecting seat 473. One end of the first transmission shaft 474 is rotationally connected to the main shaft of the first drive motor 472 via a first coupling 475, and the other end of the transmission shaft is transmission-connected to the shaft end of the lower roller 421 via a first connecting rod 476. The first drive motor 472 drives the first transmission shaft 474 and the first connecting rod 476 to rotate, thereby driving the rotation of the lower roller 421. When the lower roller assembly 42 is moved outside the machine frame, the first connecting rod 476 is disconnected from the shaft end of the lower roller 421. When the lower roller assembly 42 is moved back inside the machine frame, the first connecting rod 476 is reconnected to the shaft end of the lower roller 421.

[0062] For further information, see Figure 9As shown, the second roller drive mechanism 48 includes a second motor support 481, a second drive motor 482 mounted on the second motor support 481, a second coupling 483, and a second transmission shaft 484 rotatably mounted on the second coupling 483. One end of the second transmission shaft 484 is rotationally connected to the main shaft of the second drive motor 482 via a second coupling 485, and the other end of the second transmission shaft 484 is transmission-connected to the shaft end of the upper roller 431 via a second connecting rod 486. When the upper roller assembly 43 is moved outside the frame, the second connecting rod 486 is disconnected from the shaft end of the lower roller 421. When the upper roller assembly 43 is moved back inside the frame, the second connecting rod 486 is reconnected to the shaft end of the lower roller 421.

[0063] Preferably, both ends of the first connecting rod 476 and the second connecting rod 486 are provided with a universal joint 487, that is, the first connecting rod 476 is transmission-connected to the lower roller 421 via the universal joint 487, and the second connecting rod 486 is transmission-connected to the upper roller 431 via the universal joint 487. Even if the main shaft of the first drive motor 472 and the lower roller 421 are not coaxially arranged, and even if the main shaft of the second drive motor 482 and the upper roller 431 are not coaxially arranged, normal transmission can still be achieved.

[0064] Preferably, see Figure 5 As shown, the leveling machine frame 41 is equipped with a debris suction mechanism, which includes an exhaust fan 491, a collection box 492, a connecting pipe 493 provided at the air intake end of the exhaust fan 491, and several vertically downward-facing branch pipes 494 connected to the connecting pipe 493. The exhaust end of the exhaust fan 491 is connected to the collection box 492. The branch pipes 494 are located at the entrance of the leveling machine frame. Before the steel strip passes through the upper roller 431 and the lower roller 421 for leveling, foreign matter attached to the surface of the steel strip is first sucked out through the branch pipes 494. This reduces the amount of foreign matter adhering to the upper roller 431 and the lower roller 421, and extends the regular maintenance cycle of the steel strip leveling machine.

[0065] Preferably, see Figure 5 As shown, the bottom of the upper receiving seat 432 is provided with a docking protrusion 4101, and the top of the lower receiving seat 422 is provided with a docking seat 4102 adapted to the limiting protrusion. A groove is provided on the docking seat 4102, and the docking protrusion 4101 can be inserted into the groove of the docking seat 4102 to ensure that the positions of the upper roller 431 and the lower roller 421 are aligned to ensure the flattening effect.

[0066] The steel coil offline leveling system provided by the present invention sucks the padding paper 101 on the steel belt 211 through the paper suction mechanism 8, and the free end of the padding paper 101 is automatically moved to the front of the paper winding mechanism 1 under the drive of the mobile support seat 92, thereby solving the problems of physical energy consumption and crossing danger caused by the workers frequently crossing the pit 23 due to manual transportation of the padding paper; then, a section of double-sided tape 703 is horizontally pasted on the paper roll through the gluing head on the gluing mechanism, saving the working time of manual gluing and reducing the workload of the workers; the workers only need to align the padding paper 101 with the paper roll 10 and paste them to achieve the connection between the padding paper 101 and the paper roll 10; finally, the paper winding mechanism 1 and the unwinder 2 act synchronously, and the padding paper 101 is automatically wound into a paper roll 10 with a larger diameter. The padding paper 101 is wound neatly and tightly, which is convenient for later transportation and processing; fundamentally solves the labor consumption and recycling box cleaning problems caused by the workers' real-time collection of padding paper into the recycling box in the prior art, so the workers can leave the paper winding mechanism and take care of other work, freeing up the workers' labor.

[0067] The steel strip 211 is conveyed to the leveling mechanism 4 for leveling and shaping. After the leveling mechanism 4 reaches its specified operating time, foreign matter may accumulate on the surface of the steel strip, causing surface defects on the steel strip 211 and degrading the quality of the steel strip 211. The push-off mechanism moves the lower roller assembly 42 and the upper roller assembly 43 from inside the leveling frame 41 to the outside of the leveling frame 41, providing ample working space for workers to clean the surfaces of the upper roller 431 and the lower roller 421. Each section of the roller surface can be cleaned thoroughly, improving cleaning efficiency and effectiveness.

[0068] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the scope of protection of the present invention.
