In addition, in actual production, the thickness of metal strips of different batches of coils is generally different. The height of the feed port of the existing straightening mechanism is fixed. It cannot straighten metal strips whose thickness is greater than the height of the feed port, and its scope of application is relatively small. Utility Model Content
