This technology discloses that "the center of the cam has an axial hole concentric with the base circle, and the wall of the axial hole has a keyway parallel to the axis. The cam is composed of a part that guides the steel ring plate to rise and a part that guides the steel ring plate to fall. The ratio of the central angles of the two parts is 2:1, and the difference between the maximum radius and the minimum radius is 48mm. The technical scheme has the technical effects of improving the forming of the bobbin and significantly reducing the unwinding of the bobbin when the bobbin is unwound at high speed."
