Problems solved by technology

[0005] In order to overcome and make up for the large compressive stress of the inner winding of the optical fiber caused by the existing constant tension winding method of optical fiber, there is a large difference in stress and strain between the inner and outer layers of the winding, which greatly affects the signal transmission performance of the optical fiber winding and cannot meet the requirements of optical fiber winding. Due to the technical deficiencies and defects of winding stability requirements, the present invention provides a variable tension adjustment and control device that can be used for optical fiber precision winding. It uses a printed winding motor as a variable tension adjustment and control device. The motor drives the miniature ball screw transmission pair to make the position of the travel code change precisely in the length direction of the swing rod, and the angle sensor is used to detect the position of the swing rod, so that the swing rod is kept in a horizontal position under the state of torque balance. By changing the travel code The position and the precise detection and control of the horizontal balance position of the pendulum make the tension of the optical fiber after layer-changing winding reach a new stable value requirement, thus realizing the automatic adjustment and control of the variable tension of the optical fiber winding during layer-changing winding
