Description

Technical Field

[0001] The utility model relates to the field of winding equipment, in particular to a wire winding wheel quick-installation mechanism. Background Art

[0002] The wire winding wheel is a component used in conjunction with a winder. It is widely used in winding wires, steel cables, electrical cables, mesh cloth and other products that need to be wound and stored. Since the wire winding wheel needs to be replaced after it is fully wound, the reel as a transmission rotating component is usually set to be suspended at one end, and the wire winding wheel is required to be able to be installed and disassembled on the reel. However, the current wire winding wheel is fixed to the reel by bolts distributed on the outside of the reel. The bolts need to be disassembled and assembled during the replacement of the wire winding wheel, and the replacement speed is slow. At the same time, a wrench needs to be used for disassembly, and the steps are cumbersome and the practicality is poor. After long-term and frequent disassembly and assembly, the threaded holes on the wire winding wheel are prone to slippage and failure, affecting the stability of the connection and the service life.
