[0022] As Figures 1-3The utility model provides a kind of steel band two-level flattening mechanism, as shown in the drawings 1,2,3,4,5, the utility model provides a kind of steel band two-level flattening mechanism, including guide mechanism 1, the side of guide mechanism 1 is equipped with first compression roller group 2 and second compression roller group 3 in proper order, guide mechanism 1 includes guide platform 4, two rotating shafts 6 are fixed on guide platform 4, the axis of rotating shaft 6 is perpendicular to the top surface of guide platform 4, rotating shaft 6 is rotatably connected with connecting barrel 5 by angle reset device, the side wall of connecting barrel 5 is fixed with connecting plate 8, connecting plate 8 is fixed with the telescopic link 7 of horizontal arrangement, the telescopic end of telescopic link 7 is all fixed with vertical limit plate 9, two limit plates 9 are close to each other, limit plate 9 is equipped with multiple through slots, vertical shaft 10 is rotatably arranged in through slot, first compression roller group 2 includes first roller support, hollow roller 11 and support roller are rotatably connected on first roller support, hollow roller 11 is rotatably connected with vibration roller shaft 12 in, eccentric block 13 is fixed on vibration roller shaft 12, vibration roller shaft 12 is driven by driving device.The driving device and angle reset device are all existing step motor or servo motor etc.The rotating shaft 6 is connected with angle sensor, and the angle sensor is prior art.

[0023] In use, the steel band to be flattened is placed in the guide area formed between the two limit plates 9, when the axis of the steel band and the compression roller group is inclined, the steel band will drive the connecting barrel 5 to rotate through the limit plates 9, telescopic links 7 and connecting plates 8, at this time, the relative angle between the connecting barrel 5 and the rotating shaft 6 will change, which is detected by the angle sensor or manually, then the angle reset device is started to reset the relative angle between the connecting barrel 5 and the rotating shaft 6, so that the limit plates 9 can limit the steel band, the flattening process is more intelligent and accurate through the angle sensor, and problems in the flattening process can be found in time, the production efficiency and product quality are improved. The multiple vertical grooves on the limit plate 9 can rotate flexibly through the vertical shaft 10 connected to the vertical groove when the steel band passes, which facilitates the conveying of the steel band. After the steel band passes through the guide mechanism 1, the driving device is started to drive the eccentric roller shaft to rotate in the hollow roller 11, because the vibration roller shaft 12 drives the eccentric block 13 to rotate, the hollow roller 11 can vibrate, the vibration of the hollow roller 11 can generate greater pressure, so that the steel band can be preliminarily flattened, and the pressure on the steel band can be flexibly adjusted according to the different thickness and hardness of the steel band, the flattening effect is improved, the steel band preliminarily flattened by the first compression roller group 2 is continuously conveyed to the second compression roller group 3 for further flattening treatment, so that the steel band can reach the required flatness, and the power required by the second compression roller group 3 is reduced.

[0024] As Figures 1-4As shown, the vertical shaft 10 includes a limiting shaft 14, the side wall of the upper part of the limiting shaft 14 is provided with threads, the limiting shaft 14 is connected with a limiting sleeve 15 through threads, the bottom end of the limiting sleeve 15 is provided with a rotating cavity, a guide ball 16 rotates in the rotating cavity, the bottom end of the guide ball 16 can abut against the top surface of the steel belt, the bottom end of the limiting plate 9 is fixed with a support plate 17, and the support plates 17 are close to each other. During the leveling process of the steel belt, the limiting sleeve 15 is rotated, the limiting sleeve 15 moves up and down along the threads, the limiting sleeve 15 abuts against the top surface of the steel belt through the guide ball 16 in the rotating cavity, so as to limit the shaking of the steel belt, even if the steel belt is impacted and pressed, the guide mechanism 1 and the steel belt can also remain stable, the smooth leveling process is ensured, the stability of the leveling effect is improved, the guide ball 16 can flexibly roll according to the movement of the steel belt, the friction and wear of the limiting sleeve 15 on the steel belt are reduced, and stable limiting is provided, which helps to keep the stable transmission of the steel belt.

[0025] As shown in Figures 1-4 , the top end of the limiting shaft 14 is fixed with an adjusting rod 18, and the adjusting rod 18 penetrates the limiting plate 9. Due to the limitation of the manufacturing size of the vertical groove, there is not enough space for a wrench or the like to drive the limiting sleeve 15 to rotate. By arranging the adjusting rod 18, the limiting sleeve 15 can be clamped by a tool when the height of the limiting sleeve 15 is adjusted, the limiting shaft 14 and the limiting sleeve 15 are relatively rotated, and then the position of the limiting sleeve 15 is adjusted up and down. By penetrating the limiting plate 9 through the adjusting rod 18, the adjusting operation is more direct and convenient, the position change of the steel belt during the leveling process can be quickly responded, and timely adjustment is performed, so that the smooth leveling process is ensured.

[0026] As shown in Figure 1 , 4 , 5, two scissor lifting platforms 19 are arranged on the first roller frame, the scissor lifting platforms 19 are fixed with rotating blocks, and the two ends of the upper roller are rotationally connected with adjacent rotating blocks. The scissor lifting platform 19 is prior art.

[0027] As shown in Figure 1As shown, the second pressure roller group 3 includes a second roller frame, on which a solid roller 20 and a lower roller are rotatably connected. The solid roller 20 and the lower roller are driven by a motor. The motor can be a conventional stepper motor or a servo motor. The combination of the solid roller 20 and the lower roller in the second pressure roller group 3 allows the solid roller 20, due to its rigidity and weight, to more effectively flatten and straighten the steel strip, helping to eliminate localized ripples caused by the vibration of the first pressure roller group 2, thereby ensuring the flattening effect of the steel strip. Driving the solid roller 20 and the lower roller with a drive device ensures that both rotate at the same speed, thus preventing slippage or stretching of the steel strip as it passes through the pressure roller group.

[0028] like Figures 1-3 As shown, the rotating shaft 6 is provided with a scale 21. During use, the connecting cylinder 5 is rotated to the initial reference position and aligned with the zero mark of the scale 21 line. The scale 21 can provide an intuitive visual reference, and basic operation can still be maintained through the scale 21 even in the event of sensor failure.
