Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a winding device for a transformer iron core. Background Art

[0002] The transformer core is the core component of the transformer, usually made of laminated silicon steel sheets. Its function is to increase the magnetic permeability of the transformer, thereby improving the efficiency of the transformer. The core can effectively concentrate the magnetic field, reduce magnetic energy loss, and make the power conversion more efficient. The existing transformer core slitting line needs to use a winding device to wind up the transformer core slitting line during processing.

[0003] Most of the existing winding devices for transformer cores drive the winding roller to rotate through the drive of a motor to complete the winding of the transformer core slitting line. However, most of the existing winding devices do not have a structure for adjusting the winding position of the transformer core slitting line, resulting in the transformer core slitting line wound on the winding roller piling up, and the transformer core slitting line is not wound evenly, resulting in a waste of space. Therefore, we propose a winding device for transformer core. Utility Model Content

When the winding roller 3 winds up the transformer core slitting line, it is installed between the drive shaft 13 and the rotating connecting rod 14 by disassembling the assembly. The rotating connecting rod 14 is rotatably connected to the inner wall of the U-shaped frame 2 through the bearing. The transformer core slitting line passes through the limit sleeve 11 and is then wound on the winding roller 3. After starting the servo motor 12, the drive shaft 13 can be driven to rotate, so that the winding roller 3 between the drive shaft 13 and the rotating connecting rod 14 rotates.
