Technical Field
[0001] This utility model relates to the technical field of steel coil leveling equipment, and in particular to a feeding and leveling system. Background Technology
[0002] Steel coils are thin steel sheets rolled into a coil shape, offering unique advantages in storage and transportation. The first step in steel coil production is leveling. Currently, various leveling equipment exists. The utility model patent CN213591444U, an adjustable-height cold-rolled steel coil leveling machine, is a specialized steel coil leveling device. This utility model can adjust the height of the first extrusion roller 7, thereby adjusting the gap size between the second extrusion roller 10 and the first extrusion roller 7; this gap provides space for the steel coil sheet to pass through; the adjustment of this gap size can accommodate steel coils of different thicknesses. However, the first extrusion roller 7 and the second extrusion roller 10 are arranged in a one-to-one correspondence; the first extrusion roller 7 is positioned directly above the second extrusion roller 10. This means that when the leveling machine aligns the steel coil, the downward pressure of the first extrusion roller 7 cannot exceed the upper surface of the second extrusion roller 10, resulting in poor stress relief for maintaining the curvature within the steel coil. This leads to a less than ideal leveling effect for the steel coil. Utility Model Content

[0030] Compared with the prior art, the upper support roller and lower pressure roller 23 of this utility model can cooperate with each other to fully compress the steel coil 0, eliminate the internal stress of the steel coil 0, and help ensure the leveling effect of the steel coil 0.

[0033] The middle section 2 of the leveling section also includes a synchronous shaft 291; the end of the synchronous shaft 291 is coaxially fixed to the inward input end of the worm gear screw jack 214; the synchronous shaft 291 enables the lifting blocks 213 on both sides to rise and fall synchronously, ensuring the levelness of the lower pressure roller 23.
[0034] The support rollers 4 of the front guide 1 are arranged along an arc; inside the front guide 1, the front support rollers 4 are set lower than the rear support rollers 4; the support rollers 4 of the rear guide 3 are arranged along a horizontal straight line; in this way, the steel coil 0 can be smoothly unfolded in the front guide 1, so as to facilitate the leveling in the leveling middle section 2.
[0035] A retaining roller 11 is provided above the support roller 4 in the middle of the guide front part 1 to block the steel ring and prevent most of the steel coil 0 from being pulled to the middle of the leveling part 2 and crushed.
[0036] The guide front part 1 also includes front sidewalls 12 arranged symmetrically on the left and right; the end of the support roller 4 is rotatably connected to the front sidewall 12; the end of the retaining ring roller is rotatably connected to the front sidewall 12 to reduce the flow resistance of the steel coil 0.
[0037] The middle section 2 of the leveling section also includes a tensioning screw 292; both ends of the tensioning screw 292 pass through the vertical sidewall 21 and are threaded with nuts 293; the tensioning screw 292 drives the vertical sidewall 21 to move closer to the middle and is supported by the upper support roller to ensure the vertical stability of the vertical sidewall 21.

The clamping plate 523 is arranged inward and fixed to the top of the guide plate 522. The edges of the steel coil 0 are restricted to ensure its smooth flow. The double-ended screw 53 has a positive thread section and a negative thread section at both ends. The centering parts 52 on the left and right sides are respectively fixed with screw nuts 54 that cooperate with the positive thread section and the negative thread section. The end of the double-ended screw 53 is coaxially fixed with a handwheel 55. The handwheel 55 is operated to rotate the double-ended screw 53. The rotating double-ended screw 53 moves the centering parts 52 in the same direction or opposite direction through the screw nuts 54 to achieve the centering effect, so that the steel coil 0 is centered and the leveling center 2 is leveled smoothly.
[0039] The centering component 52 of the front guide 1 is inclined; the inclination angle of the centering component 52 matches the arc of the support roller 4 of the front guide 1; the centering component 52 of the rear guide 3 is horizontal; thus, the two centering mechanisms 5 are more adaptable to the flow of steel coils 0.
[0040] The working principle of this embodiment is as follows: the front guide 1 guides the steel coil 0, allowing it to smoothly pass through the leveling center 2 for leveling; the rear guide 3 pulls the leveled steel coil 0 for conveying the steel; the rotating support roller 4 reduces the resistance encountered by the steel coil 0 during its flow; the worm gear screw jack 214 is activated by operating the handwheel A 215, causing the lifting block 213 and the lower pressure roller 23 to rise and fall, which serves to compress the steel coil 0 and facilitates the installation of the end of the steel coil 0 in the leveling center 2; the upper support roller and the lower pressure roller 23 cooperate to fully compress the steel coil 0, eliminating internal stress and ensuring the leveling effect; the motor 24 outputs torque, which drives the drive roller A 222 to rotate through the sprocket A 25, chain 27, and sprocket B 26, providing power for the flow of the steel coil 0. The pressure roller 281 cooperates with the drive roller B 223 to provide flow power for the steel coil 0 at the front end of the leveling center 2.
[0041] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the guide rods 51 are symmetrically arranged on both sides of the double-ended screw 53 to ensure that the centering member 52 is at a stable tilt angle.
[0042] The top of the clamping plate 523 is provided with a longitudinal observation hole 5231, which can be used to observe the clamping effect of the clamping plate 523 on the edge of the steel coil.
