Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a winding mechanism for slitting machines. Background Art

[0002] Slitting machine, also known as slitting line, slitting machine, slitting machine, is a name for metal slitting equipment. It is suitable for longitudinal shearing of metal strips and rewinding the slit narrow strips into rolls. It has the characteristics of easy operation, high cutting quality, high material utilization rate, and stepless cutting speed regulation.

[0003] This type of winding mechanism is widely used in the longitudinal shearing process of metal, plastic, paper and other materials. It is particularly suitable for production environments with high requirements for coiled materials. The general longitudinal shearing machine consists of unwinding (unwinding), material positioning, strip longitudinal shearing, and winding (rewinding). It can shear tinplate, silicon steel sheets, aluminum strips, copper, stainless steel plates, galvanized plates, etc., and is widely used in transformers, motors, home appliances, automobiles, building materials, packaging and other industries.

[0004] However, when existing longitudinal shears are wound up after completing the shearing work, the winding drums used are all drums with fixed radius. When facing different materials, since the radius of the drum cannot be directly changed, the entire drum must be replaced when necessary, which makes the existing drum have certain limitations and has a certain impact on production progress and production efficiency.
