Inner tight outer loose bobbin control device

Abstract

The invention relates to a tight-inside-and-loose-outside type cone yarn control device which comprises a buoy and a yarn creel, wherein a push device is arranged at the bottom of the buoy, and the yarn creel is arranged nearby the buoy. The tight-inside-and-loose-outside type cone yarn control device is characterized in that the buoy further comprises an upper cap and a lower cap that are nested together; a floating spring is arranged in a cavity formed by the upper cap and the lower cap jointly; the push device is arranged at the bottom of the lower cap; a push rod arranged on the push device stretches into the lower cap and is abutted against the floating spring; a pressure groove for a yarn to pass is formed in the top of the upper cap; two yarn guide wheels are arranged at the two sides of the pressure groove respectively; a guide wheel is arranged in the pressure groove; a gravity sensor is arranged on the yarn creel, and is in data connection with the push device; and a winding transmission device is arranged on the yarn creel.

Description

technical field [0001] The invention relates to a weaving device, in particular to an inner tightening and outer loosening type bobbin control device. Background technique [0002] Cone cone yarn has many advantages such as easy unwinding, not easy to fall off, etc. In the whole spinning process, cone cone yarn is an indispensable yarn weave form. Due to the needs of the next process, many processes often require the production of cones. shaped yarn. [0003] During the winding process of the bobbin, the winding yarn gradually increases on the winding drum, and the bobbin becomes more and more wound. The problem that will be encountered in reality is the poor formation of the package yarn winding. One of the problems is that the yarn of the inner layer (inner ring) on ​​the package yarn is gradually tightened by the yarn of the outer layer (outer ring), so that the inner layer yarn The thread is easy to form wrinkles on the end faces of both ends of the package yarn, and e...

Problems solved by technology

The problem that will be encountered in reality is the poor formation of the package yarn winding. One of the problems is that the yarn of the inner layer (inner ring) on ​​the package yarn is gradually tightened by the yarn of the outer layer (outer ring), so that the inner layer yarn The thread is easy to form wrinkles on the end faces of both ends of the package yarn, and even the inner layer yarn is loose, and if the inner layer yarn is loose, the outer layer yarn is also easy to collapse to the inner layer, resulting in poor forming of the package yarn, During the unwinding process of the latter, the bobbin will be difficult to unwind
