Single-shaft pay-off machine

The utility model relates to a pay-off machine, in particular to a single-shaft pay-off machine which is used for wire winding of a motor, and belongs to the field of motor auxiliary equipment. The single-shaft pay-off machine comprises a base, a bracket which is fixed to the base and a rotating shaft, wherein the rotating shaft penetrates through the bracket and is fixed to a bearing seat through a bearing; an iron wheel and a brake band are arranged at one end, close to the bracket, of the rotating shaft; a spring is arranged between a tension bracket and the base; the tension bracket is connected with a brake through a pull rod; the pull rod is driven to tighten the brake when the wire winding stops through the force generated by the deformation of the spring; the effect of preventing a bobbin from wire loosening is achieved.
