Description

Technical Field

[0001] The utility model relates to the technical field of steel strip conveying mechanisms, in particular to a steel strip conveying mechanism of an automatic steel strip butt welding machine. Background Art

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width and its length varies slightly according to the size of each roll.

[0003] The existing Chinese patent with publication number CN103878266A discloses a steel belt conveying mechanism for conveying steel belts. The feeding mechanism includes a feeding roller, a disc rotating device, an intermediate lead-out roller and a pulling device. The disc rotating device includes a disc and a plurality of vertical rollers arranged in a spiral shape in the disc. A bracket is provided under the disc. The vertical roller is connected to a power device, which provides power for the rotation of the vertical roller. The intermediate lead-out roller is arranged above the disc. After the steel belt is drawn out from the steel belt disc, it is pulled by the feeding roller and spirally enters the center of the disc rotating device from the outer edge of the disc rotating device. Then, the steel belt spirally leaves the center of the disc rotating device in the opposite direction of rotation to that of entering the disc rotating device, and then is guided into the pulling device through the intermediate lead-out roller. Compared with the prior art, the present invention has a simple structure, is easy to manufacture, has low cost, saves energy, has high conveying efficiency, and solves the problems of steel belt jamming, twisting, tearing, etc.

At the same time, it is impossible to adjust according to strips of different widths. Therefore, it is necessary to propose a steel strip conveying mechanism for an automatic steel strip butt welding machine. Utility Model Content
