Description

Technical Field

[0001] The invention relates to the technical field of metal strip winding, in particular to a slitting machine winding mechanism for metal strips. Background Art

[0002] At present, when the raw metal strip has a large number of prepared winding layers, during the process of slitting it, due to the influence of factors such as the length, weight, and tension of the metal strip, the distance between the unwinding output end of the prepared metal strip and the slitting roller is generally less than the length of the metal strip between them. In order to avoid continuous output of the metal strip, the distance between the tangent point of the prepared winding strip output and the slitting roller changes. Therefore, the metal strip is made to fall in a concave shape, and the output unwinding and input unwinding of the prepared winding strip and the metal strip collection roller are coordinated. However, the problems that arise are that the conveying tension of the metal strips output after being slit by the slitting rollers is low, causing the metal strips to become loose. In addition, because the metal strips cut by the slitting rollers are separated at slightly equal intervals, the tension of the metal strips cannot be too high when they are rolled up, resulting in larger gaps in the layers of the rolled metal strips, causing the metal strips to become loose easily. Moreover, when the metal strips are cut into strips, and when the metal strips are separated and continuously conveyed, the cut edges of the metal strips become warped, resulting in an uneven surface of the metal strips.

[0003] Therefore, those skilled in the art provide a slitting machine winding mechanism for metal strips to solve the problems raised in the above background technology. Summary of the Invention
