Description

Winder is used in production of microcrystalline iron core Technical Field The utility model relates to the technical field of coil winding of microcrystalline iron cores, in particular to a winding machine for microcrystalline iron core production. Background The coil of the microcrystalline iron core needs to be rolled into small rolls in the manufacturing process so as to be convenient for subsequent installation and use, and the winding machine plays a key role in the process and is mainly responsible for uniformly and tightly winding the large coiled material into small rolls meeting the specification, so that the continuity, the integrity and the consistency of the coil are ensured. The winding machine consists of a wire material supply system, a winding head, a tension control system, a guiding device, a cutting and fixing device, a control system and the like. The wire is continuously supplied from the wire coil and guided to the winding head through the guiding device, the wire is wound into a loop along a preset path by the winding head driven by the motor, and the tension control system ensures that the wire maintains stable tension in the winding process, so that the loosening or overtightening of the loop is avoided.
