Cone yarn unwinding device suitable for core-spun yarn production

Abstract

The present invention provides a cone yarn unwinding device suitable for core-spun yarn production. The cone yarn unwinding device suitable for core-spun yarn production comprises a handle, a hemispherical unwinding disc and a connecting rod; the handle is connected with the semispherical unwinding disc; the connecting rod is connected with the semispherical unwinding disc; a strong magnet is arranged at the lower end of the connecting rod. The cone yarn unwinding device is provided with the handle, so that the device is very convenient to use; and moreover, the strong magnet is arranged at the lower end of the connecting rod, the strong magnet attracts the bolt of a cone yarn tension sleeve, so that the cone yarn unwinding device is very stable and not prone to falling off or sliding whenplaced on the bobbin of cone yarn.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to a bobbin unwinding device suitable for core-spun yarn production. Background technique [0002] The high-strength core-spun sewing thread is made of polyester staple fiber and polyester filament, and adopts the structure of polyester staple fiber core-spun polyester filament. In order to obtain better quality single yarn (less neps, less hairiness) ) The yarn tension applied during winding production is often set relatively small, and the resulting single-yarn yarn is relatively soft. At the same time, because the yarn has a smooth surface and strong rigidity, taper is used in the subsequent doubling process. The unwinding of the single yarn of the tube is prone to stripping. In order to overcome this problem, we choose parallel winding tubes for winding when producing this variety, and the winding single yarns using parallel winding tubes are produced in parallel. However, afte...

[0002] The high-strength core-spun sewing thread is made of polyester staple fiber and polyester filament, and adopts the structure of polyester staple fiber core-spun polyester filament. In order to obtain better quality single yarn (less neps, less hairiness) ) The yarn tension applied during winding production is often set relatively small, and the resulting single-yarn yarn is relatively soft. At the same time, because the yarn has a smooth surface and strong rigidity, taper is used in the subsequent doubling process. The unwinding of the single yarn of the tube is prone to stripping. In order to overcome this problem, we choose parallel winding tubes for winding when producing this variety, and the winding single yarns using parallel winding tubes are produced in parallel. However, after repeated use of parallel winding tubes, burrs are prone to appear at both ends of the tubes. Due to the appearance of burrs, the winding single yarn will be broken when the small yarn is unwound. The burr is caught and the yarn is broken, which seriously affects the production of doubling

At present, this kind of endless small yarn can only be cut off and treated as waste yarn, which greatly reduces the production rate and increases the production cost
