Abstract

The invention discloses a multifunctional ultra-large-stroke yarn storage and unwinding device, and belongs to a yarn storage and unwinding device of a two-dimensional and three-dimensional knitting machine. The yarn unwinding device comprises a light sensing communication signal acquisition device, a winding and unwinding yarn storage driving device assembly and a constant tension unwinding device; the winding and unwinding yarn storage driving device assembly is installed on a spindle seat of the light sensing communication signal acquisition device, and the constant tension unwinding deviceis located at the upper end of the winding and unwinding yarn storage driving device assembly; and a bolt penetrates through the yarn storage device shaft seat of the constant-tension unwinding device and the winding yarn storage driving device to be connected to the spindle seat of the light sensing communication signal acquisition device. The multiple groups of driving devices are connected inseries to increase the winding and unwinding stroke of the yarn storage device by four times, when the torsion of the multiple groups of driving devices reaches the limit, the yarn storage device overcomes the rated expansion force and friction and can keep unwinding of yarns, and a purpose of winding and unwinding the yarns continuously with over-large stroke and constant tension, noises do not exist, and the service life is long. The multifunctional ultra-large-stroke yarn storage and unwinding device has the advantages that an optical fiber acquisition signal controls the device to stop sensitively when yarns are broken, faults are positioned accurately, the energy is saved, consumption is reduced, and the device has lots of functions; and two-dimensional and three-dimensional weaving quality is improved, and a weaving range is expanded.
