The patent (CN216150710U) discloses a steel strip leveling device for cold rolling of stainless steel, including a bottom plate, rollers, support legs and a support frame, wherein the rollers are arranged at the bottom end of the bottom plate, the support legs are arranged at the four corners of the upper end of the bottom plate, the support frame is arranged at the upper end of the support legs, guide plates are arranged on the inner and outer walls of the support frame, guide wheels are arranged on the guide plates, a gantry is arranged above the support frame, and a cylinder 1 is arranged on one side wall of the gantry. The beneficial effect is that the utility model is provided with cylinder 2, connecting frame 2 and flattening roller 2. During flattening, cylinder 2 pushes flattening roller 2 downward through connecting frame 2, thereby causing the flattening roller to apply pressure to the lower surface of the steel strip, and at the same time, the upper and lower surfaces of the steel strip can be subjected to force at the same time in cooperation with flattening roller 1, and the convexities and concave marks on the upper and lower surfaces of the steel strip can be processed at the same time, thereby ensuring the leveling effect of the device and improving the practicality of the device.

The first auxiliary roller frame 3 and the second auxiliary roller frame 8 have the same structure. The first auxiliary roller frame 3 and the second auxiliary roller frame 8 are arranged alternately. The first auxiliary roller frame 3 and the second auxiliary roller frame 8 cooperate with each other to perform auxiliary rolling support at the top and bottom of the stainless steel strip, perform pretreatment on the stainless steel strip before flattening, reduce the surface stress of the stainless steel strip, and facilitate the subsequent flattening of the surface of the stainless steel strip; the first auxiliary roller frame 3 is horizontally provided with a rotatably connected first auxiliary roller 15 at the bottom, and the second auxiliary roller frame 8 is horizontally provided with a rotatably connected second auxiliary roller 16 at the top, and the spacing between two adjacent first auxiliary rollers 15 and the spacing between two adjacent second auxiliary rollers 16 are The first auxiliary roller 15 and the second auxiliary roller 16 cooperate with each other to provide rolling contact support with the upper and lower surfaces of the stainless steel strip to ensure the stability of the movement of the stainless steel strip; the top of the second auxiliary roller 16 and the top of the first smoothing roller 42 of the second smoothing roller frame 7 are located on the same horizontal line, and the bottom horizontal position of the first auxiliary roller 15 is located below the bottom position of the first smoothing roller 42 of the first smoothing roller frame 6. The positions of the first auxiliary roller 15, the second auxiliary roller 16 and the first smoothing roller 42 are set to ensure that the first auxiliary roller 15 and the second auxiliary roller 16 cooperate to form a cross channel, and the stainless steel strip passes through the cross channel to perform stress relief treatment.

The specific implementation method is as follows: by setting a lifting plate 2, a first auxiliary roller frame 3, a first through groove 4, a first visual inspection component 5, a first leveling roller frame 6, a second leveling roller frame 7 and a second auxiliary roller frame 8, the stainless steel strip to be processed is placed on the inner side of the leveling machine frame 1, and the stainless steel strip passes through the first auxiliary roller frame 3 and the second auxiliary roller frame 8, the first leveling roller frame 6 and the second leveling roller frame 7, and the first visual inspection component 5 and the second visual inspection component 41 in sequence; the lifting plate 2 is adjusted to lift and lower, and the lifting plate 2 drives the first auxiliary roller frame 3, the first visual inspection component 5 and the first leveling roller frame 6 to lift and lower, and the first auxiliary roller frame 3 and the second auxiliary roller frame 8 cooperate to perform auxiliary rolling processing on the stainless steel strip, and the first leveling roller frame 6 and the second leveling roller frame The roller frames 7 cooperate with each other to perform rolling and leveling processing on the stainless steel strip, the first visual inspection component 5 performs visual inspection processing on the upper surface of the stainless steel strip to realize the defect detection work on the surface of the stainless steel strip, and the second visual inspection component 41 performs visual inspection processing on the lower surface of the stainless steel strip to realize the double-sided defect detection work on the surface of the stainless steel strip; the lifting and lowering adjustment of the lifting plate 2 can effectively adjust the vertical spacing of the first auxiliary roller frame 3 and the second auxiliary roller frame 8, and can effectively adjust the vertical spacing of the first leveling roller frame 6 and the second leveling roller frame 7, thereby realizing the leveling processing of stainless steel strips of different thicknesses, and at the same time, the force applied to the surface leveling processing of the stainless steel strip can be adjusted, so that the leveling processing effect of the stainless steel strip is better;

As the lifting plate 2 is adjusted downward, the first auxiliary roller frame 3, the first visual inspection component 5 and the first leveling roller frame 6 are adjusted downward, and the first leveling roller frame 6 moves toward the second leveling roller frame 7. As the first leveling roller frame 6 gradually moves downward, the two first leveling rollers 42 in the first leveling roller frame 6 and the second leveling roller frame 7 press the stainless steel strip tightly for roller pressing and leveling. Multiple groups of first leveling roller frames 6 and second leveling roller frames 7 cooperate to effectively level the surface of the stainless steel strip for multiple times, and the leveling processing surface of the stainless steel strip is larger. A flattening force can be applied to the surface of the stainless steel strip between the multiple groups of first leveling roller frames 6 and second leveling roller frames 7, which can effectively improve the leveling effect of the stainless steel strip.

The second smoothing roller 11 at the end of the first support frame 9 first contacts and abuts against the surface of the stainless steel strip, and the first smoothing roller frame 6 continues to move downward, and the first support frame 9 swings along the first rotating shaft 10, and the second smoothing roller 11 rolls along the surface of the stainless steel strip until the first smoothing roller 42 of the first smoothing roller frame 6 contacts and abuts against the surface of the stainless steel strip. During this process, the first torsion spring performs elastic torsional support between the first rotating shaft 10 and the first support frame 9, so that the second smoothing roller 11 is always elastically tightened against the surface of the stainless steel strip, and as the first smoothing roller 42 gradually moves downward, the greater the swing angle of the first support frame 9, the greater the elastic torsional force of the first torsion spring, and the greater the elastic tightening force between the second smoothing roller 11 and the stainless steel strip. The second smoothing roller 11 at the end of the first support frame 9 can perform rolling and smoothing treatment on the surface of the stainless steel strip on both sides of the first smoothing roller 42, which can effectively increase the rolling and smoothing treatment area of the stainless steel strip surface, and can effectively improve the smoothing treatment effect on the surface of the stainless steel strip;

When the second smoothing roller 11 at the end of the first support frame 9 rolls and contacts the surface of the stainless steel strip, the third smoothing roller 14 at the end of the second support frame 12 also contacts and resists the surface of the stainless steel strip. As the first smoothing roller 42 gradually moves downward, the swing angle of the first support frame 9 gradually increases, and the angle between the first support frame 9 and the surface of the stainless steel strip gradually decreases. The third smoothing roller 14 and the surface of the stainless steel strip are pressed tightly, and the second support frame 12 swings along the second rotating shaft 13, and the third smoothing roller 14 rolls along the surface of the stainless steel strip. The second torsion spring performs elastic torsion support between the second rotating shaft 13 and the second support frame 12, and the third smoothing roller 14 performs rolling and smoothing treatment on the surface of the stainless steel strip between the first smoothing roller 42 and the second smoothing roller 11, which can effectively improve the rolling and smoothing treatment effect on the surface of the stainless steel strip.

At the same time, the working principles of the first support frame 9, the second smoothing roller 11, the second support frame 12 and the third smoothing roller 14 on the outer side of the second smoothing roller frame 7 are the same as the working principle of the first smoothing roller frame 6. After the two first smoothing rollers 42 distributed above and below are aligned to achieve force balance, the upper and lower surfaces of the stainless steel strip are subjected to roller pressing and smoothing treatment; after the two second smoothing rollers 11 distributed above and below are aligned to achieve force balance, the upper and lower surfaces of the stainless steel strip are subjected to elastic roller pressing and smoothing treatment, and a group of second smoothing rollers 11 are respectively arranged on both sides of each group of first smoothing rollers 42, which can effectively expand the smoothing treatment range of the stainless steel strip by the first smoothing roller frame 6 and the second smoothing roller frame 7, thereby improving the smoothing treatment effect of the stainless steel strip; after the two third smoothing rollers 14 distributed above and below are aligned to achieve force balance, the upper and lower surfaces of the stainless steel strip are subjected to elastic roller pressing and smoothing treatment, and a group of third smoothing rollers 14 are arranged between each group of first smoothing rollers 42 and second smoothing rollers 11, which can perform auxiliary rolling and smoothing treatment on the inner side of the smoothing treatment range of the stainless steel strip surface, thereby further improving the rolling and smoothing treatment effect of the stainless steel strip;

Before the stainless steel strip is pulled and conveyed, since the second support frame 12 is located between the first support frame 9 and the first smoothing roller 42, the second torsion spring provides elastic torsion support to the second support frame 12. When the first support frame 9 and the second support frame 12 press down on the surface of the stainless steel strip, the first support frame 9 and the second support frame 12 tilt and move in opposite directions, so that the second smoothing roller 11 and the third smoothing roller 14 move in opposite directions along the surface of the stainless steel strip, and the two second smoothing rollers 11 and the third smoothing rollers 14 distributed up and down move along the upper and lower surfaces of the stainless steel strip, so that the second smoothing roller 11 and the third smoothing roller 14 extrude and flatten the surface of the stainless steel strip, ensuring that the stainless steel strip is smoother and more stable between the second smoothing roller 11 and the third smoothing roller 14. Since the first support frame 9 is symmetrically arranged on the first flat On both sides of the leveling roller 42, the first support frames 9 located on both sides of the first leveling roller 42 tilt and move in opposite directions, and the second support frames 12 located on both sides of the first leveling roller 42 tilt and move in opposite directions, so that the two second leveling rollers 11 located on both sides of the first leveling roller 42 move in opposite directions along the surface of the stainless steel strip, and the two third leveling rollers 14 located on both sides of the first leveling roller 42 move in opposite directions along the surface of the stainless steel strip, and the two groups of second leveling rollers 11 and third leveling rollers 14 distributed up and down on both sides of the first leveling roller 42 move along the upper and lower surfaces of the stainless steel strip, so that the second leveling rollers 11 and the third leveling rollers 14 extrude and flatten the surface of the stainless steel strip on both sides of the first leveling roller 42, further ensuring that the stainless steel strip is more flat and stable between the second leveling rollers 11 and the third leveling rollers 14;

When the stainless steel strip is roller-leveled, the stainless steel strip is pulled and conveyed, and the stainless steel strip passes through the first auxiliary roller frame 3, the second auxiliary roller frame 8, the first leveling roller frame 6 and the second leveling roller frame 7 in sequence. Before the stainless steel strip passes through the two first leveling rollers 42, the stainless steel strip first passes through the two second leveling rollers 11 of the first support frame 9 on one side of the first leveling roller 42. The two second leveling rollers 11 therein roll and clamp the stainless steel strip under the elastic force of the first torsion spring. The first support frame 9 is driven by the stainless steel strip to approach the first leveling roller 42, and the elastic forces of the two groups of second leveling rollers 11 distributed up and down are the same, so that the stainless steel strip is in a flush position between the two first leveling rollers 42, which can effectively improve the leveling effect of the stainless steel strip and ensure the stability of the stainless steel strip. The second support frame 12 on the first support frame 9 here moves along with the first support frame 9 as a whole to the first leveling roller 42 is close, and in addition, the second support frame 12 swings under the elastic support of the second torsion spring, so that the third smoothing roller 14 is always in close contact with the surface of the stainless steel strip for rolling and guiding, so that the stainless steel strip maintains balance during the rolling and smoothing process, thereby improving the smoothing effect of the stainless steel strip; after the stainless steel strip passes between the two first smoothing rollers 42, it moves to the first support frame 9 on the other side, and the stainless steel strip first rolls with the third smoothing roller 14 on the second support frame 12. The third smoothing roller 14 is pulled away from the first smoothing roller 42, and the second support frame 12 of the first smoothing roller 14 pushes the first support frame 9 away from the first smoothing roller 42.

The specific implementation method is as follows: by setting a servo motor 17, a first connecting rod 18, a second connecting rod 19, a sliding plate 20, a camera 21, a support bar 23, a first sector gear 25, a second sector gear 28 and a gear 29, when the first visual detection component 5 and the second visual detection component 41 are working, taking the first visual detection component 5 as an example: the servo motor 17 drives the first connecting rod 18 to rotate, one end of the first connecting rod 18 rotates along the output shaft of the servo motor 17, and the other end of the first connecting rod 18 performs a circular motion along the output shaft of the servo motor 17, one end of the second connecting rod 19 swings along the first connecting rod 18, and the other end of the second connecting rod 19 drives the sliding plate 20 to slide back and forth along the first through groove 4, and the camera 21 slides along the first through groove 4 with the sliding plate 20, so that the camera 21 can reciprocate along the width direction of the stainless steel belt, and the camera 21 can perform visual acquisition processing on different width positions of the stainless steel belt surface, which can effectively improve the defect detection and processing effect on the stainless steel belt surface;

When the sliding plate 20 slides along the first through slot 4, the gear 29 on the side wall of the sliding plate 20 meshes with the third rack 30, so that when the sliding plate 20 slides back and forth along the first through slot 4, the gear 29 performs rotational movement in positive and negative directions, the gear 29 drives the second support shaft 27 to perform rotational movement in positive and negative directions, and the second support shaft 27 drives the second sector gear 28 to perform rotational movement in positive and negative directions; after the sliding plate 20 slides from one end to the other end along the first through slot 4 and then reciprocates, when the sliding plate 20 slides in one direction along the first through slot 4, before turning, the gear 29 also rotates in one rotation direction, and after turning, when the sliding plate 20 slides in the other direction of the first through slot 4, the gear 29 rotates in the opposite direction;

Before the sliding plate 20 slides and turns, the gear 29 rotates in the same direction. When the second sector gear 28 rotates to mesh with the second rack 26, the second sector gear 28 continues to rotate, and the second sector gear 28 drives the second rack 26 to slide. The second rack 26 drives the support bar 23 to slide, and the first rack 24 slides with the support bar 23. The spring 31 is compressed, and the first rack 24 and the first sector gear 25 are meshed with each other, driving the first sector gear 25 to swing. The first sector gear 25 drives the camera 21 to swing through the first support shaft 22, so that the camera 21 slides along the first through groove 4 while moving. The first through slot 4 is swung in a row, and the swinging direction is perpendicular to the length direction of the first through slot 4, which can effectively expand the visual image acquisition area of the stainless steel strip surface by the camera 21, and can also perform visual image acquisition processing on the stainless steel strip surface at different angles, thereby effectively improving the defect detection processing effect on the stainless steel strip surface; when the second sector gear 28 rotates to separate from the second rack 26, the second sector gear 28 no longer has the supporting force for the second rack 26, the spring 31 rebounds to push the support bar 23 back, and the first rack 24 at the bottom of the support bar 23 drives the first sector gear 25 to swing and reset, thereby realizing the swing reset of the camera 21;

After the sliding plate 20 slides and turns, the gear 29 rotates in the opposite direction. The principle is the same as above, but the swing direction of the camera 21 is opposite to that before, which can further increase the visual image acquisition area of the stainless steel strip surface by the camera 21. At the same time, the visual image acquisition and processing of the stainless steel strip surface can be performed at different angles, further improving the defect detection and processing effect on the stainless steel strip surface.

The working principle of the second visual inspection component 41 is the same as that of the first visual inspection component 5. The second visual inspection component 41 performs visual image acquisition and processing at different width positions and angles on the lower surface of the stainless steel strip, which can effectively ensure the defect detection and processing effect of the second visual inspection component 41 on the lower surface of the stainless steel strip.
