The inlet tension roller group, the straightening roller group and the outlet tension roller group are structurally and schematically shown in figure 1. The inlet tension roller group comprises four tension rollers, namely a first tension roller, a second tension roller, a third tension roller and a fourth tension roller, the first tension roller, the second tension roller, the third tension roller and the fourth tension roller are sequentially far away from an aluminum strip conveying inlet along the direction of aluminum strip winding conveying, and the second tension roller and the third tension roller are farthest away in the inlet tension roller group. The outlet tension roller group comprises four tension rollers, namely a fifth tension roller, a sixth tension roller, a seventh tension roller and an eighth tension roller, the fifth tension roller, the sixth tension roller, the seventh tension roller and the eighth tension roller are sequentially far away from the straightening roller group along the direction of the aluminum strip winding conveying, and the sixth tension roller and the seventh tension roller are farthest in the outlet tension roller group. The tension rollers are respectively wound, and the aluminum strip is wound between the rollers and tensioned by the rollers.
When the existing stretch bending straightener is used for stretch bending straightening of a thin aluminum foil, when the distance between two rollers is long, namely the distance between a second tension roller and a third tension roller and the distance between a sixth tension roller and a seventh tension roller, the aluminum foil is flattened by the front rollers, but because the shape of the aluminum foil is not an ideal flat surface, under the condition of tension, the aluminum foil can generate a arris phenomenon (unevenness), the arris is easy to wrinkle when passing through the next roller, and the farther the distance between 2 rollers is, the more the aluminum foil is easy to wrinkle.
The normal technological parameter requirements of the aluminum foil with the thickness of 0.06-0.09mm are as follows: the uncoiling tension is 5000-. If the aluminum foil with the thickness of 0.06-0.09mm is produced on a stretch bending straightener by force according to a normal production process, the roller way and the installation precision are not very high because the material is thin, the aluminum foil is easy to wrinkle, fold and the like under the action of large tension to cause scrappage, and if the aluminum foil is produced by small tension, tower shape and staggered layers are easy to generate in coiling, and the requirements cannot be met. Therefore, for the aluminum foil with the thickness less than 0.09mm, the plate shape can not be corrected by adopting stretch bending correction equipment, so that the plate shape ratio is poorer, and some products can only be scrapped because the plate shape can not meet the requirements of customers.
