Description

Technical Field

[0001] The utility model relates to the field of winding, in particular to an adjustable cutting and winding mechanism. Background Art

[0002] The winding equipment is mainly used for winding the film material. After winding, the film material is cut by the cutter, and then the abrasive is torn apart by the tension of the winding equipment, thus completing the entire winding work.
