技术问题technical problem

现有卷绕设备通常包括将各料带送至卷针卷绕工位的各送料装置，以及在卷绕完成后将各料带切断的各切刀机构等。现有的卷绕设备在卷绕元件完成卷绕后，各切刀机构将各个料带切断，如此，在进行下一卷绕元件的卷绕前，各送料机构需要先将各料带送至卷绕工位，然后，卷针开始下一卷绕元件的卷绕，这使得生产两个卷绕元件之间的时间延长，影响了卷绕设备的生产效率。此外，现有的卷绕设备通常结构复杂，体积庞大，会使占地面积增大。The conventional winding apparatus generally includes each of the feeding devices that feed the respective belts to the winding winding station, and the respective cutter mechanisms that cut the respective belts after the winding is completed. In the existing winding apparatus, after the winding elements are wound, each cutter mechanism cuts the respective strips. Thus, before the winding of the next winding element is performed, each feeding mechanism needs to send the strips to the strips first.

In addition, the existing winding equipment is usually complicated in structure and bulky, which increases the floor space.
