Summary: | The utility model discloses a servo tensioner which comprises a shell. The side face of the shell is provided with a wire passing device, the front face of the shell is provided with a tension device, the shell is further provided with a tension adjustment device and a control circuit, and the wire passing device, the tension device and the tension adjustment device are respectively connected with the control circuit. The work principle of the servo tensioner is as follows: in the wire winding process, when a certain section of a wire needs larger tension, a sensor detects that tension decays firstly and generates a signal, the signal is sent to a step motor through a control circuit of a PCBA, the step motor drives a tension wheel to feed the wire actively, and ultimately the step motor and a cylinder respectively carry out corresponding motions. The magnitude of tension is switched through the cylinder and is adjusted through pull force of a tension spring, and accordingly tension force is constant, the str |
