Description

Technical Field

[0002] The width of the metal coils produced by the steel rolling mill is very large, which does not meet the width of the metal coils required by the buyers. Therefore, it is necessary to cut the wider metal coils into multiple smaller metal strips according to the buyers' needs.

[0003] The slit metal strip needs to be wound on a reel. There are several slots on the outer wheel surface of the reel. The slots extend axially along the reel. Workers manually bend the head of the metal strip to form a hook, and then insert the hook into the slot of the reel. The reel rotates to drive the metal strip to be wound.

[0004] Since the slit metal strips are closely arranged, if they are directly wound, the edges of two adjacent metal strips will overlap each other, causing winding failure. Therefore, before inserting the strips into the slot, workers need to pull the strips apart along the axis of the reel to avoid overlapping.

[0005] All of the above winding processes need to be completed manually by workers, which has low work efficiency, low degree of automation, and is time-consuming and labor-intensive. Summary of the invention
