Abstract
The utility model discloses a ball-top feeding apparatus with tension automatical adjuster, wherein, a feed roller is connected with a driving shaft of an unwinding roller set, and the driving shaft of the unwinding roller set is equipped with an electromagnetic clutch. The electromagnetic clutch is connected with the unwinding roller set through a drive pair, and a wool strip limiting bar is provided between the unwinding roller set and the corresponded feed roller. A first position sensor of the wool strip is arranged on the external common tangent of the wool strip limiting bar and the feed roller. The external side of the external common tangent is equipped with a second position sensor of the wool strip. The position sensors are connected with a controlling circuit of the electromagnetic clutch, and the controlling circuit of the electromagnetic clutch is connected with the corresponded electromagnetic clutch. The unwinding roller set is driven by a gear set, and the linear speed of the unwinding roller set is faster than the pulling speed of the feed roller, so the wool strip is kept at a relaxed state. The position sensors are used to measure the location of the wool strip, and when the wool strip is tensioned or over relaxed, the unwinding roller set is operated by the electromagnetic clutch to rotate or stop to recover the proper tension of the wool strip. The draw-deformation of the wool strip is effectively avoided, and the quality of the wool outlet is improved.
