The tension detection mechanism 35 is used to detect the tension of the electrode roll and to feed back the tension magnitude during the electrode roll conveying process to the tension swing roller mechanism 27 or to the control element and then to the tension swing roller mechanism 27. The tension swing roller mechanism 27 adjusts to the tension required by the equipment according to the feedback tension data, thereby realizing the self-adjustment control of the tension.

No secondary correction positioning is required, the cutting accuracy is maintained and it is easy to adjust, reducing the number of processes, increasing work efficiency, and reducing investment costs.
