Feeding device for tire wire winding machine

Abstract

The invention discloses a feeding device for a tire wire winding machine and aims to solve problems of poor steel wire friction quality, proneness to accumulation and instability of steel wire tensionin the prior art. Two ends of a spool are supported on a let-off supporting frame through a let-off rotating shaft and a clamping part, and one end of the spool is in detachable connection with one end of the let-off rotating shaft. A let-off frequency-variable motor is mounted on one side of the let-off supporting frame, and an output shaft of the let-off frequency-variable motor is in transmission connection with the other end of the let-off rotating shaft through a let-off speed-reduction diverter. A let-off fixed wheel set is rotationally supported on the let-off supporting frame througha fixing support arm, and a let-off moving wheel set is rotationally supported at an output end of the let-off supporting frame through a moving support arm. An angular displacement sensor between thelet-off supporting frame and a rotating connector is in electrical connection with a controller, and the controller is in electrical connection with the let-off frequency-variable motor through a frequency converter. The feeding device has advantages that friction of steel wires is avoided, high quality and tension stability of steel wires are realized, butt joints are less prone to breakage, stability in operating and braking of the spool is achieved, and less proneness to accumulation is realized.

Description

technical field [0001] The invention relates to the production of bead rings or bead cores, especially a feeding device for tire steel wire winding machines. Background technique [0002] In order to improve the rigidity of the tire bead so as to increase the bearing capacity of the tire, steel wire rings are provided at the tire bead. At present, the traveler is generally formed by winding a wire winding machine. The wire winding machine usually includes a forming roller and a feeding device. The steel wire is fed by the feeding device, pulled by the forming roller and wound in the forming groove on the forming roller. After winding and forming, it is cut, bonded and glued to form a traveler. spare. [0003] The feeding device of the existing wire winding machine usually includes a guide mechanism and a material storage mechanism. The guide mechanism includes a guide bracket, an I-shaped wheel, a guide shaft and a double-groove aluminum wheel. On the shaft, both ends of ...
