[0002] Magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. Nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic devices.

[0003] Announcement No. (CN214898057U) discloses a core encapsulation device for a high-frequency transformer. The user places the transformer in the inner cavity of the positioning frame, drives the movable plate to move by starting the electric telescopic rod, fixes the transformer by moving the movable plate, pulls the tape to wrap it around the surface of the transformer, drives the rotating rod to rotate by starting the driving motor, drives the mounting plate to rotate by the rotation of the rotating rod, drives the positioning frame to rotate by the rotation of the mounting plate, and then drives the transformer to rotate, completing the winding of the tape by itself. The above device cannot accurately control the thickness of the tape wrapped around the core, which will cause the thickness of the tape wrapped around each core to be inconsistent, and needs to be improved.
