Tension adjusting device for cable production

The utility model belongs to the technical field of cable tension adjustment, and particularly relates to a tension adjusting device for cable production, which comprises a device body, and one side of the device body is rotatably connected with a turntable through a bearing seat. The pressure sensor and the extrusion block are arranged between the rotating disc and the adjusting plate, the two tension wheels are arranged on one side of the adjusting plate, the cable only needs to be wound around the two tension wheels in an S-shaped path, then the tension of the cable can be adjusted by rotating the rotating disc, and the device is easy and convenient to operate and high in practicability. The practicability and the adjusting efficiency of the tension adjusting device are effectively improved, an adjusting plate can rebound under the action of tension, so that a first spring on an extrusion block can extrude a pressure sensor, the tension adjusted by the adjusting device can be known in time through the pres
