[0012] The accumulator temporarily stores a part of the steel strip through the height difference of the movable block and the movable roller in the support frame, and the amount of the temporarily stored steel strip is proportional to the height of the accumulator and the number of the rollers. When the uncoiler at the front end of the production line feeds a large amount of material, the movable block and the movable roller are lowered to store material under the action of gravity, and when the material storage is full at the bottom end of the column, the movable block and the movable roller can be lifted by overcoming the weight, so that the steel strip shifting caused by the speed difference between the front-end equipment and the rear-end cold bending forming machine is avoided, the speed difference between the front end and the rear end is solved, the feeding demand of the cold bending forming machine is ensured, and the problems of scratches or bending marks and other strip defects are avoided.
[0013] The vertical accumulator has the advantages of simple structure, small floor area, weight storage, no power, saving of equipment cost and operation cost, generation of the sleeve tension by the weight of the movable roller, no strip breakage in the production process, reduction of equipment failure and improvement of safety.
