Description

Technical Field

[0001] The utility model belongs to the technical field of rolling mills and relates to a reeling and unreeling sleeve for rolling an extremely thin metal strip. Background Art

[0002] Controlling the tension of ultra-thin metal strips during the rolling process is a very important part, and the first step in controlling the tension is to coil the ultra-thin metal strips. However, because the thickness of the thin strips is very small, it is very easy to slip during the coiling process, resulting in the inability to coil. Therefore, the end of the ultra-thin metal strip needs to be inserted into the strip groove.

[0003] In the traditional winding process, a plurality of belt grooves are arranged on the winding sleeve, and the belt grooves for winding are not only difficult to install, but also it is easy for the extremely thin metal belt to break inside when removing the extremely thin metal belt. Once the extremely thin metal belt breaks inside, it is not only difficult to remove it, but also the belt groove can only be abandoned when it cannot be removed, which is very time-consuming and laborious. Utility Model Content

[0004] In view of this, the utility model provides a reeling and unreeling sleeve for rolling an ultra-thin metal strip in order to solve the problem that it is inconvenient, time-consuming and labor-intensive to assemble and disassemble the ultra-thin metal strip on the reeling sleeve in traditional reeling.
