Steel wire winding and unwinding tensioning guide structure

Abstract

The invention provides a steel wire winding and unwinding tensioning guide structure. The structure enables a motor to drive a corresponding one-way bearing to act in a one-way mode in the wire penetrating process, ensures stable and reliable actions of wire winding and wire penetrating, and ensures stable and reliable operation of a flat knitting machine. The steel wire winding and unwinding tensioning guide structure comprises a driving mounting frame, the driving mounting frame comprises a connecting plate used for being fixedly connected with a rack, a motor mounting plate used for being fixedly provided with a driving motor and a connecting frame used for mounting a reel, the back face of the motor mounting plate is fixedly connected with a machine shell of the driving motor, a transmission shaft of the driving motor protrudes out of the motor mounting plate forwards, a first one-way bearing and a second one-way bearing are sequentially arranged on the forward protruding portion of the transmission shaft in a sleeving mode in the axial direction of the transmission shaft, the active rotating directions of the first one-way bearing and the second one-way bearing are opposite, afirst transmission gear is fixedly arranged on an outer ring of the first one-way bearing in a sleeving mode, a second transmission gear is fixedly arranged on an outer ring of the second one-way bearing in a sleeving mode, and the first transmission gear is in engaged connection with a third transmission gear.

Description

technical field [0001] The invention relates to the technical field of flat knitting machine structures, in particular to a steel wire retractable tension guide structure. Background technique [0002] The retraction and unwinding of the steel wire of the existing flat knitting machine is directly completed by driving the motor to drive the wire winding wheel to rotate. Since the motor directly drives the wire winding wheel to rotate forward or reverse, a set of pressing wheels is set at the entrance and exit of the steel wire to make The steel wire is in a relatively tight state when retracting and unwinding, but in the actual process, since the wire winding wheel is a driving wheel, the tension is relatively weak only through a set of pinch wheels during its rotation, and the pinch wheels are easy to launch and Loosening, and then making the whole steel wire can not be fully tightened, so that the steel wire is easy to slide relative to the reel, and then the steel wire ca...

[0002] The retraction and unwinding of the steel wire of the existing flat knitting machine is directly completed by driving the motor to drive the wire winding wheel to rotate.
