Description

Technical Field

[0001] This invention relates to the field of high-nickel stainless steel cold rolling technology, specifically to a high-nickel stainless steel cold rolling equipment with automatic loading and unloading function. Background Technology

[0002] Stainless steel cold rolling equipment refers to a complete set of industrial equipment systems that further roll hot-rolled stainless steel coils into thinner and more precise strips or plates at room temperature. Its core purpose is to improve the dimensional accuracy, surface quality, and mechanical properties of stainless steel to meet the high-requirement applications of industries such as home appliances, automobiles, construction, and medical care. High-nickel stainless steel is an indispensable key material in modern industry. Its high hardness, corrosion resistance, and high temperature resistance make it the preferred material in fields such as nuclear engineering, marine engineering, aerospace, and high-end chemical equipment.

[0003] Traditional stainless steel cold rolling equipment can automatically load and unload stainless steel coils using a coil feeding car. When ordinary stainless steel coils are fed onto the conveyor shaft, the guide plate on the cold rolling equipment rises and, in conjunction with the conveyor shaft, gradually extends the stainless steel coil onto the guide plate. The flattening rollers on the guide plate flatten the passing stainless steel coil to facilitate its smooth entry into the cold rolling mill. However, due to the inherent high strength and hardness of high-nickel stainless steel coils, they remain relatively bent even after being pressured by the flattening rollers during the conveyor shaft's transport to the guide plate. Therefore, manual intervention is required to forcibly straighten them before feeding them into the cold rolling mill. Otherwise, they will gradually be fed into the lower part of the cold rolling mill along the bending angle and will not be able to enter between the upper and lower rollers. This process is time-consuming and labor-intensive, and manual operation is also dangerous. Furthermore, before cold rolling, high-nickel stainless steel coils may have some metal dust or other adhering substances on their surface. After cold rolling, these adhering substances will become integrated with the surface of the high-nickel stainless steel coil, affecting the quality of the finished product.

[0004] Therefore, a high-nickel stainless steel cold rolling equipment with automatic loading and unloading function is proposed. Summary of the Invention

The rotating wheel has four sets arranged symmetrically in two rows. During the installation of the stainless steel coil, the feeding carriage on the right side of the base will slide along the second movable slide to move the high-nickel stainless steel coil onto the conveyor shaft. Then, the second support frame will be driven by the motor to rotate on the sliding seat, so that the receiving hole is aligned with the conveyor shaft. After that, the sliding seat will slide along the first movable slide to the conveyor shaft so that the receiving hole is connected with the conveyor shaft, completing the receiving of the end of the conveyor shaft. Then, the conveyor shaft will be driven by the motor to rotate the high-nickel stainless steel coil along the rotating wheel, so that its beginning is exposed above the feeding carriage. At this time, the installation of the high-nickel stainless steel coil on the conveyor shaft is completed.

[0008] Preferably, the pressing assembly includes a support plate, a pressing plate, and a pressing roller; the support plate is fixedly connected to the right side of the base, the pressing plate is rotatably connected to the top of the support plate, and the pressing roller is rotatably connected to the end of the pressing plate; when the high-nickel stainless steel coil is loaded onto the conveyor shaft, the pressing plate will be driven by the motor to rotate counterclockwise along the support plate, and the pressing roller will press against the top of the high-nickel stainless steel coil on the conveyor shaft to prevent the top of the high-nickel stainless steel coil from becoming loose.

[0009] Preferably, the inlet assembly includes a fixed frame, a first drive motor, a first rotating shaft, a rotating plate, an arc-shaped pressure groove, a rotating roller, an inlet plate, a mounting groove, an electric push rod, a fixed sliding sleeve, a toothed plate, a notch, a second drive motor, a drive gear, a second rotating shaft, and a lower pressure roller; the fixed frame is fixedly connected to the right side of the lifting seat, the first drive motor is fixedly connected to the outside of the fixed frame, the first rotating shaft is rotatably connected to the fixed frame, the output shaft of the first drive motor is fixedly connected to the first rotating shaft, the rotating plate is fixedly connected to the first rotating shaft, the arc-shaped pressure groove is opened near the left side of the rotating plate, multiple sets of rotating rollers are provided and distributed along the arc of the arc-shaped pressure groove and rotatably connected to the arc-shaped pressure groove, the inlet plate is slidably connected to the right side of the rotating plate, the mounting groove is opened below the rotating plate, the electric push rod is fixedly installed in the mounting groove, and the output end of the electric push rod is fixedly connected to the inlet plate, two sets of fixed sliding sleeves are provided and fixedly connected to both sides of the rotating plate, the toothed plate is slidably connected to the fixed sliding sleeve, and the notch is opened... Located on the left side of the fixed sliding sleeve, the second drive motor is fixedly connected to the outside of the fixed sliding sleeve. The drive gear is fixedly connected to the output shaft of the second drive motor. The drive gear is located at the notch and meshes with the toothed plate. The toothed plate is slidably connected to the fixed sliding sleeve. The second rotating shaft is rotatably connected to the top of the toothed plate. The lower pressure roller is fixedly connected to the second rotating shaft. After the high-nickel stainless steel coil is installed on the conveyor shaft, the first drive motor drives the rotating plate to rotate, causing the guide plate to rotate to below the beginning of the high-nickel stainless steel coil. Then, the first drive motor rotates in the opposite direction, causing the rotating plate to swing upward. During the upward swing, the guide plate is pushed by the electric push rod to gradually extend out of the rotating plate, placing the beginning part of the high-nickel stainless steel coil on top of the guide plate. Then, the rotating plate will fix this angle. During the process of the high-nickel stainless steel coil moving from the right side to the left end of the arc-shaped pressure groove, it is subjected to the pressure of the lower pressure roller. The high-nickel stainless steel coil will move along the arc of the arc-shaped pressure groove, thereby applying reverse pressure to correct the long-term bent state.

[0010] Preferably, the guiding assembly includes a truss and a guide plate; the truss is fixedly connected to the top of the fixed frame, and the guide plate is fixedly connected to the bottom of the truss. The right end of the guide plate is bent upwards, and the left end of the truss extends to near the upper roller. When the high-nickel stainless steel coil passes through the guide plate, the guide plate can guide the high-nickel stainless steel coil into the space between the upper roller and the lower roller, preventing the high-nickel stainless steel coil from bending in the opposite direction after being corrected by the pressure of the lower roller and thus not being able to move directly between the upper roller and the lower roller.

[0011] Preferably, the cleaning assembly includes an extension frame, a vertical chute, a sliding block, a second elastic element, a sweeping roller, a groove, a swing block, a brush, a first elastic element, a first gear, a second gear, a third gear, a fourth gear, a chain, and a transmission component; the extension frame is fixedly connected to the top of the toothed plate, the vertical chute is fixedly connected to both ends of the extension frame, the sliding block is slidably connected to the vertical chute, one end of the second elastic element is fixedly connected to the vertical chute, and the other end is fixedly connected to the top of the sliding block; the sweeping roller is provided in two sets, one set rotating with the right side of the arc-shaped groove. The cleaning roller is connected to a sliding block, with another set of rotatably connected between the two sets of sliding blocks. Multiple sets of grooves are formed on the circumferential surface of the cleaning roller. The swing block is rotatably connected to the groove, and the axial connection between the swing block and the sidewall of the groove is located at the bottom of the swing block. Two sets of swing blocks are symmetrically arranged along the center of each groove. The brush is fixedly connected to the swing block. One end of the elastic element is fixedly connected to the sidewall of the groove, and the other end is fixedly connected to the swing block. Gear 1 is fixedly connected to the central shaft of the rightmost rotating roller in the arc-shaped pressure groove. Gear 2 is fixedly connected to the arc-shaped pressure groove. On the central rotating shaft of the cleaning roller on the right side of the shaped pressure groove, gear one and gear two mesh. Gear three is fixedly connected to rotating shaft two, and gear four is rotatably connected to the extension frame, with gear three and gear four meshing. The rotating shaft where gear four is rotatably connected to the extension frame is connected to the central rotating shaft of the cleaning roller via a chain drive. The transmission component is located inside the cleaning roller. During the process of the rotating roller rotating counterclockwise to move the high-nickel stainless steel coil toward the cold rolling mill, the rotating roller on the right side of the shaped pressure groove will drive gear one to rotate counterclockwise, thereby driving the cleaning roller to rotate counterclockwise via gear one. When gear two rotates clockwise, it simultaneously drives the cleaning roller on the right side of the arc-shaped pressure groove to rotate clockwise, which in turn drives the brush to clean the bottom surface of the high-nickel stainless steel coil. At the same time, due to the pressing force of the lower pressure roller on the high-nickel stainless steel coil, the high-nickel stainless steel coil will drive the lower pressure roller to rotate clockwise during the movement. Meanwhile, gear three will drive gear four to rotate counterclockwise. The rotating shaft of gear four will drive the cleaning roller on the sliding block to rotate counterclockwise through the chain, which in turn drives the brush to clean the upper surface of the high-nickel stainless steel coil.

[0012] Preferably, the transmission component includes a first inclined block, a circular groove, a push plate, a second inclined block, a fixed rod, a first right-angle bracket, a second right-angle bracket, a circular plate, and a third inclined block; the first inclined block is fixedly connected to the inner side of the swing block; the circular groove is formed inside the sweeping roller; the push plate extends from the groove into the circular groove of the sweeping roller and is slidably connected to the sweeping roller; the second inclined block is fixedly connected to both sides of the end of the push plate; the fixed rod passes through the center of the sweeping roller; the first right-angle bracket is fixedly connected between the central rotating shaft of the sweeping roller on the right side of the arc-shaped pressure groove and the rotating plate; the second right-angle bracket is fixedly connected between the central rotating shaft of the sweeping roller and the sliding block; and multiple sets of circular plates are equidistantly fixedly connected to the fixed plate. On the fixed rod, the inclined block three is fixedly connected to the circular plate, and multiple sets of annular arrays are arranged on the outer ring of the circular plate. The inclined block three in the right side of the arc-shaped pressure groove and the inclined block three in the sliding block are inclined in opposite directions. During the cleaning process of the cleaning roller rotating counterclockwise, the push plate will continuously abut against the inclined block three. Affected by the inclined surface of the inclined block three, the push plate will continuously push upward as it follows the rotation of the cleaning roller, thereby pushing the inclined block two to move upward and causing the inclined block one to move to both sides. This will push the push plate to overcome the elastic force of the elastic element one and open to both sides along the bottom rotation axis. Therefore, it can drive the brush to continuously generate a flicking action during the cleaning process, which can enhance the cleaning effect on the surface of high-nickel stainless steel.

[0013] Preferably, a support block is also fixedly connected to the inner side of the swing block, and the support block is located below the second inclined block; the second inclined block can fix the falling position of the push plate to prevent the push plate from falling too much and causing direct contact with the fixed rod, resulting in large friction and affecting the stability of the sweeping roller rotation process.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up an inlet component, the high-nickel stainless steel coil is subjected to the pressure of the lower pressure roller as it moves from the right side to the left end of the arc-shaped pressure groove. The high-nickel stainless steel coil will move along the arc of the arc-shaped pressure groove, thereby applying reverse pressure to correct the bending state that has been maintained for a long time. When the high-nickel stainless steel coil passes the guide plate, the guide plate can guide the high-nickel stainless steel coil into the space between the upper and lower rollers, preventing the high-nickel stainless steel coil from bending in the opposite direction after being corrected by the pressure of the lower pressure roller and thus not being able to move directly between the upper and lower rollers.

[0016] 2. This invention, by setting up a cleaning assembly, ensures that during the downward pressing of the lower roller, the cleaning roller on the extension frame moves downward accordingly, ultimately clamping the high-nickel stainless steel coil between the cleaning roller on the extension frame and the cleaning roller on the right side of the arc-shaped pressure groove. During the process of the rotating roller rotating counterclockwise to transport the high-nickel stainless steel coil to the cold rolling mill, the rotating roller on the right side of the arc-shaped pressure groove drives gear one to rotate counterclockwise, which in turn drives gear two to rotate clockwise. Gear two simultaneously drives the cleaning roller on the right side of the arc-shaped pressure groove to rotate clockwise, thereby driving the brush to clean the bottom surface of the high-nickel stainless steel coil. At the same time, due to the pressing force of the lower roller on the high-nickel stainless steel coil, the high-nickel stainless steel coil will drive the lower roller to rotate clockwise during the movement. Meanwhile, gear three will drive gear four to rotate counterclockwise. The rotating shaft of gear four will drive the cleaning roller on the sliding block to rotate counterclockwise via a chain, thereby driving the brush to clean the upper surface of the high-nickel stainless steel coil.

[0017] 3. Since the fixed rod is stationary, the push plate will continuously abut against the inclined block three during the rotation process. Influenced by the inclined surface of the inclined block three, the push plate will continuously push upward as it follows the rotation of the cleaning roller, thereby pushing the inclined block two to move upward and causing the inclined block one to move to both sides. This will push the push plate to overcome the elastic force of the elastic element one and open to both sides along the bottom rotation axis. Therefore, it can drive the brush to continuously generate a plucking action during the cleaning process, which can enhance the cleaning effect on the surface of high-nickel stainless steel.

Component 8 is installed on the inlet assembly 6 and distributed on the upper and lower sides of the high-nickel stainless steel coil 43. During operation, the loading and unloading assembly 4 is responsible for loading and unloading the high-nickel stainless steel coil 43. Then, in cooperation with the inlet assembly 6 and the guide assembly 7, the high-nickel stainless steel coil 43 is conveyed into the space between the upper roll 31 and the lower roll 32 of the cold rolling mill 3 for cold rolling. The inlet assembly 6 can straighten the extended stainless steel coil so that it can smoothly enter the space between the upper roll 31 and the lower roll 32. The cleaning assembly 8 is responsible for cleaning the high-nickel stainless steel coil 43 before it enters the cold rolling mill 3 to prevent metal dust and other adhering substances from following the high-nickel stainless steel coil 43 into the cold rolling mill 3 and affecting the quality of the finished product.

Then, the second support frame 46 is driven by the motor to rotate on the sliding seat 45, causing the receiving hole 47 to rotate and align with the conveyor shaft 42. After that, the sliding seat 45 slides along the first sliding groove 44 towards the conveyor shaft 42, so that the receiving hole 47 aligns with the conveyor shaft 42, completing the receiving of the end of the conveyor shaft 42.

Then, the drive motor 62 rotates in the opposite direction, causing the rotating plate 64 to swing upward. During the upward swing, the guide plate 67 is pushed by the electric push rod 69 to gradually extend beyond the rotating plate 64, placing the beginning part of the high-nickel stainless steel coil 43 on top of the guide plate 67. Then, the rotating plate 64 is fixed at this angle, and the conveyor shaft 42 rotates counterclockwise to continuously convey the high-nickel stainless steel coil 43 onto the guide plate 67.

Drive gear 614 drives gear plate 611 to move lower pressure roller 616 towards rotating roller 66 until the extended high-nickel stainless steel coil 43 is pressed between rotating roller 66 and lower pressure roller 616. At this time, rotating roller 66 will be driven by electricity to rotate counterclockwise, thereby driving the extended high-nickel stainless steel coil 43 to move towards cold rolling mill 3. During the process of moving from the right side to the left end of the arc-shaped pressure groove 65, the high-nickel stainless steel coil 43 will be subjected to the pressure of lower pressure roller 616 and will move along the arc of the arc-shaped pressure groove 65, thereby applying reverse pressure to correct the long-term bent state.

The grooves 86 are formed in multiple sets on the circumferential surface of the sweeping roller 85. The swing block 87 is rotatably connected to the groove 86, and the swing block 87 is connected to the side wall of the groove 86. The shaft connection is located at the bottom of the swing block 87, and two sets of swing blocks 87 are symmetrically arranged along the center of each set of grooves 86. The brush 88 is fixedly connected to the swing block 87. One end of the elastic element 89 is fixedly connected to the side wall of the groove 86, and the other end is fixedly connected to the swing block 87. The gear 810 is fixedly connected to the central shaft of the rightmost rotating roller 66 of the arc-shaped pressure groove 65. The gear 811 is fixedly connected to the central shaft of the right cleaning roller 85 of the arc-shaped pressure groove 65, and the gear 810 and the gear 811 mesh. The gear 812 is fixedly connected to the rotating shaft 615. The gear 813 is rotatably connected to the extension frame 81, and the gear 812 and the gear 813 mesh. The rotating shaft of the gear 813 rotatably connected to the extension frame 81 is connected to the central shaft of the cleaning roller 85 through a chain 814. The transmission element 815 is located inside the cleaning roller 85.During the downward pressing process of the toothed plate 611 driving the lower pressure roller 616, the cleaning roller 85 on the extension frame 81 will move downward accordingly, eventually clamping the high-nickel stainless steel coil 43 between the cleaning roller 85 on the extension frame 81 and the cleaning roller 85 on the right side of the arc-shaped pressure groove 65. In this state, the sliding block 83 will overcome the elastic force of the second elastic element 84 and move upward. As a result, the cleaning roller 85 on the extension frame 81 will be subjected to the pushing force of the second elastic element 84, which will exert downward pressure on the high-nickel stainless steel coil 43. At this time, the rotating roller 66 rotates counterclockwise to transport the high-nickel stainless steel coil 43 to the cold rolling mill 3. During this process, the rotating roller 66 on the right side of the arc-shaped pressure groove 65 will drive the gear 810 to rotate counterclockwise, and then through the gear 810... Gear 0 drives gear 2 811 to rotate clockwise. Gear 2 811 simultaneously drives the cleaning roller 85 on the right side of the arc-shaped pressure groove 65 to rotate clockwise, which in turn drives the brush 88 to clean the bottom surface of the high-nickel stainless steel coil 43. At the same time, due to the pressing force of the lower pressure roller 616 on the high-nickel stainless steel coil 43, the moving high-nickel stainless steel coil 43 will drive the lower pressure roller 616 to rotate clockwise. Meanwhile, gear 3 812 will drive gear 4 813 to rotate counterclockwise. The shaft of gear 4 813 will drive the cleaning roller 85 on the sliding block 83 to rotate counterclockwise via chain 814, which in turn drives the brush 88 to clean the upper surface of the high-nickel stainless steel coil 43.

[0036] Reference Figures 7 to 9The transmission component 815 includes a first inclined block 8151, a circular groove 8152, a push plate 8153, a second inclined block 8154, a fixed rod 8155, a first right-angle bracket 8156, a second right-angle bracket 8157, a circular plate 8158, and a third inclined block 8159. The first inclined block 8151 is fixedly connected to the inner side of the swing block 87. The circular groove 8152 is formed inside the cleaning roller 85. The push plate 8153 extends from the groove 86 into the circular groove 8152 of the cleaning roller 85 and is connected to the cleaning roller 85. The sliding connection includes two inclined blocks 8154 fixedly connected to both sides of the end of the push plate 8153; a fixing rod 8155 passing through the center of the sweeping roller 85; a right-angle bracket 8156 fixedly connected between the central axis of the sweeping roller 85 on the right side of the arc-shaped pressure groove 65 and the rotating plate 64; a right-angle bracket 8157 fixedly connected between the central axis of the sweeping roller 85 and the sliding block 83; and multiple sets of circular plates 8158 fixedly connected at equal intervals to the fixing rod 815. 5. The inclined block 3 8159 is fixedly connected to the circular plate 8158, and multiple sets of annular arrays are arranged on the outer ring of the circular plate 8158. The inclined block 3 8159 in the cleaning roller 85 on the right side of the arc-shaped pressure groove 65 has the opposite inclination direction to the inclined block 3 8159 in the cleaning roller 85 on the sliding block 83. During the counterclockwise rotation of the cleaning roller 85, the push plate 8153 will rotate accordingly. Since the fixed rod 8155 is fixed, the push plate 8153 will continuously rotate during the rotation process. The push plate 8153, which comes into contact with the inclined block 3 8159 and is influenced by the inclined surface of the inclined block 3 8159, is continuously pushed upward as it follows the rotation of the cleaning roller 85. This pushes the inclined block 2 8154 upward, causing the inclined block 1 8151 to move to both sides. This pushes the push plate 8153 to overcome the elastic force of the elastic element 1 89 and open to both sides along the bottom rotation axis. Therefore, it can drive the brush 88 to continuously generate a plucking action during the cleaning process, which can enhance the cleaning effect on the surface of the high-nickel stainless steel coil 43.

[0037] Reference Figure 9 The swing block 87 is also fixedly connected to a support block 871, which is located below the second inclined block 8154. The second inclined block 8154 can fix the falling position of the push plate 8153 during the process of the push plate 8153 falling after passing the third inclined block 8159, and prevent the push plate 8153 from falling too much and causing direct contact with the fixed rod 8155, resulting in a large friction force and affecting the stability of the sweeping roller 85 rotation process.

[0038] Working principle: During the installation of the stainless steel coil, the feeding carriage 49 on the right side of the base 1 slides along the second movable slide 48, moving the high-nickel stainless steel coil 43 onto the conveyor shaft 42. Then, the second support frame 46, driven by the motor, rotates on the sliding seat 45, causing the receiving hole 47 to rotate and align with the conveyor shaft 42. Afterward, the sliding seat 45 slides along the first movable slide 44 towards the conveyor shaft 42, aligning the receiving hole 47 with the conveyor shaft 42, thus completing the receiving of the end of the conveyor shaft 42. Then, the conveyor shaft 42, driven by the motor, drives the high-nickel stainless steel coil 43 to rotate along the rotating wheel 410, causing... The coil feeding carriage 49 is exposed at its beginning, positioned above the coil feeding carriage 49. At this point, the installation of the high-nickel stainless steel coil 43 on the conveyor shaft 42 is completed. Then, the drive motor 62 drives the drive shaft to rotate the rotating plate 64, causing the guide plate 67 to rotate below the beginning of the high-nickel stainless steel coil 43. Then, the drive motor 62 rotates in the opposite direction, causing the rotating plate 64 to swing upward. During the upward swing, the guide plate 67 is pushed by the electric push rod 69 to gradually extend beyond the rotating plate 64, placing the beginning part of the high-nickel stainless steel coil 43 on top of the guide plate 67. Then, the rotating plate 64... With this angle fixed, the conveyor shaft 42 rotates counterclockwise, continuously conveying the high-nickel stainless steel coil 43 onto the guide plate 67. When the high-nickel stainless steel coil 43 is conveyed into the arc-shaped pressure groove 65, the drive motor 613 drives the drive gear 614 to rotate. The drive gear 614 drives the transmission plate 611 to move the lower pressure roller 616 towards the rotating roller 66 until the extended high-nickel stainless steel coil 43 is pressed between the rotating roller 66 and the lower pressure roller 616. At this time, the rotating roller 66 will be electrically driven to rotate counterclockwise, thereby driving the extended high-nickel stainless steel coil 43 towards the cold rolling mill 3. As the high-nickel stainless steel coil 43 moves from the right side to the left end of the arc-shaped pressure groove 65, it is subjected to the pressure of the lower pressure roller 616. The high-nickel stainless steel coil 43 will move along the arc of the arc-shaped pressure groove 65, thereby applying reverse pressure to correct the bending state that has been maintained for a long time. When the high-nickel stainless steel coil 43 passes the guide plate 72, the guide plate 72 can guide the high-nickel stainless steel coil 43 into the space between the upper roller 31 and the lower roller 32, preventing the high-nickel stainless steel coil 43 from bending in the opposite direction after being corrected by the pressure of the lower pressure roller 616, and thus preventing it from moving directly between the upper roller 31 and the lower roller 32.

[0039] During the downward pressing of the lower roller 616, the cleaning roller 85 on the extension frame 81 will move downward accordingly, eventually clamping the high-nickel stainless steel coil 43 between the cleaning roller 85 on the extension frame 81 and the cleaning roller 85 on the right side of the arc-shaped pressure groove 65. In this state, the sliding block 83 will overcome the elastic force of the second elastic element 84 and move upward. Consequently, the cleaning roller 85 on the extension frame 81 will be subjected to the downward pressure of the high-nickel stainless steel coil 43 by the pushing force of the second elastic element 84. At this time, the rotating roller 66 rotates counterclockwise to transport the high-nickel stainless steel coil. As the steel coil 43 moves toward the cold rolling mill 3, the rotating roller 66 on the right side of the arc-shaped pressure groove 65 drives gear 1 810 to rotate counterclockwise, which in turn drives gear 2 811 to rotate clockwise. Gear 2 811 simultaneously drives the cleaning roller 85 on the right side of the arc-shaped pressure groove 65 to rotate clockwise, thereby driving the brush 88 to clean the bottom surface of the high-nickel stainless steel coil 43. At the same time, due to the pressing force of the lower pressure roller 616 on the high-nickel stainless steel coil 43, the high-nickel stainless steel coil 43 moves... Roll 43 will drive the lower pressure roller 616 to rotate clockwise, while gear three 812 will drive gear four 813 to rotate counterclockwise. The shaft of gear four 813 will drive the cleaning roller 85 on the sliding block 83 to rotate counterclockwise via chain 814, thereby driving the brush 88 to clean the upper surface of the high-nickel stainless steel roll 43. At the same time, the push plate 8153 will rotate with the cleaning roller 85. Since the fixed rod 8155 is stationary, the push plate 815 will rotate during the rotation. 3 will continuously come into contact with the inclined block 3 8159, and under the influence of the inclined surface of the inclined block 3 8159, the push plate 8153 will continuously push upward as it follows the rotation of the cleaning roller 85, thereby pushing the inclined block 2 8154 to move upward, causing the inclined block 1 8151 to move to both sides, thereby pushing the push plate 8153 to overcome the elastic force of the elastic element 1 89 and open to both sides along the bottom rotation axis. Therefore, it can drive the brush 88 in the cleaning process to continuously generate a plucking action, which can enhance the cleaning effect on the surface of the high nickel stainless steel coil 43.

[0040] After the stainless steel coil is pressed, the sliding seat 45 on the left side of the base 1 will disengage from the conveyor shaft 42, the support frame 2 46 will rotate upwards to be outside the straight running path of the high-nickel stainless steel coil 43, the coil feeding car 49 will move to the bottom of the high-nickel stainless steel coil 43 and rise to support the high-nickel stainless steel coil 43, and move the high-nickel stainless steel coil 43 away from the conveyor shaft 42, thereby completing the unloading.
