Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, in particular to a cutting knife device of a winding machine. Background Art

[0002] After the winder completes winding, it will automatically change the winding core. Before changing, the equipment needs to automatically cut the material and wind it onto another winding core. Most of the existing cutters use straight strips for longitudinal cutting and use the blade to cut the material in a straight line along the axis of the winding roller. When the straight strip type is used, when the material width is large, the difficulty of making the blade increases, and when the material tension is insufficient, the cutting edge will often cause the material to stretch and deform due to the impact, resulting in poor straightness of the cutter and uneven cutting.
