Description

Technical Field

[0001] The utility model relates to the technical field of textile winding mechanisms, and particularly relates to a yarn bobbin loading and unloading mechanism for a winding machine. Background Art

[0002] Winding machines are mainly used in fields such as rubber hose lines, nylon, polyester cord, polyester rope winding, high-tech fibers, coated yarns, artificial grass filaments, lithium-ion battery production, coated fiberglass, monofilaments, multifilaments, flat filaments (monofilament or multi-strand winding), and false twist spindles.

[0003] In existing textile winding machines, to improve processing efficiency, multiple yarn bobbins are arranged in parallel by setting up an insertion rack for simultaneous winding or unwinding. Although the processing efficiency can be improved, the loading and unloading are rather troublesome. If manual labor is used, a large amount of working hours will be wasted. In the prior art, the loading and unloading work can be carried out through a lifting mechanism cooperating with multiple clamping devices. However, the existing clamping devices are generally motor-driven mechanical clamping devices, which will not only cause deformation of the yarn bobbin due to the clamping force in the opposite direction, but also have a complex structure. When damaged, the maintenance cost is relatively high, and there is room for further improvement. Summary of the Utility Model
