Dancer detecting mechanism capable of achieving variable-tension adjustment and control

Abstract

The invention discloses a dancer detecting mechanism capable of achieving variable-tension adjustment and control. The dancer detecting mechanism can be particularly used for variable-tension precise adjustment and control during layer changing winding of optical fiber windings. According to the dancer detecting mechanism capable of achieving variable-tension adjustment and control, a minitype ball screw transmission pair is driven by a stepping motor to enable the position of a sliding poise in the length direction of a swing rod to be changed accurately, position detection is conducted on the swing rod through an angle transducer, and thus the swing rod is kept at the horizontal position in the moment balance state. Through changing of the position of the sliding poise and precise detection and control over the horizontal balanced position of the swing rod, the tension of an optical fiber which is wound after layer changing can meet the requirement for a new stable value, automatic variable-tension adjustment and control during layer changing winding of the optical fiber windings are achieved, the stress difference and the strain difference, which are caused by increase of the number of layers of the optical fiber windings, between an inner layer and an outer layer can be eliminated, the optical fiber windings can be finally wound on the premise that that the stress of the inner layer and the stress of the outer layer are equal, and thus the signal transmission performance and the stability of the optical fiber windings are improved remarkably.

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 dancing wheel detection mechanism that can be adjusted and controlled by variable tension. Precise changes occur on the swing rod, and the angle sensor is used to detect the position of the swing rod, so that the swing rod can be kept in a horizontal position under the state of moment balance. The fiber tension after winding reaches a new stable value requirement, thus realizing the automatic adjustment and control of the variable tension when the fiber winding layer is wound.
