Reel mechanism and winding device for flexible copper clad laminate

A reel mechanism, comprising:

• a rotating roller;
• and
• a winding belt wound around a surface of the rotating roller;
• wherein the winding belt is configured for winding a flexible copper clad laminate;
• wherein the reel mechanism further comprises first limit structures and second limit structures;
• the first limit structures and the second limit structures are arranged on one side of the winding belt away from the rotating roller;
• the first limit structures are spaced apart from the second limit structures in an axial direction of the rotating roller;
• wherein the first limit structures and the second limit structures are arranged along a length direction of the winding belt;
• the first limit structures and the second limit structures protrude from a surface of the winding belt;
• a space between the first limit structures and the second limit structures is configured for accommodating the flexible copper clad laminate;
• when the winding belt is wound with at least two layers outside the rotating roller, adjacent layers of the winding belt are spaced apart by the first limit structures and the second limit structures.
