On-line detection device and spinning machine for yarn breakage

Abstract

The present invention relates to the technical field of spinning equipment, in particular to an on-line detection device for yarn breakage and a spinning machine, comprising a snap-press mechanism and an alarm trigger assembly, the snap-press mechanism is located under the spun yarn to be tested, and the alarm trigger The assembly includes a conductive bump installed on the upper surface of the snap-press mechanism and a conductive sheet that matches the conductive bump installed above the snap-press mechanism. When the elastic pressing mechanism moves upward until the conductive bumps are in contact with the conductive sheet, the alarm will give an alarm. The invention can realize the online detection of spinning yarn production, and avoid the error caused by the yarn breakage detected by the yarn tension of the spinning yarn. Judgments and omissions.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, and specifically relates to an on-line detection device for yarn breakage and a spinning machine. Background technique [0002] When the spun yarn passes through high-speed textile equipment, it may cause end breakage and spindle tape slippage, which will cause hundreds of times or even thousands of times the damage in the subsequent process. Therefore, how to quickly and timely detect the spinning Yarn breakage has become a top priority. The existing intelligent online detection device detects whether the spun yarn is broken by means of the thread tension of the spun yarn during the weaving process. However, due to different textile processes, it is easy to change the movement path, Changes in the angle with the spindle pulley, etc., lead to changes in its friction, resulting in changes in line tension, which is prone to misjudgment and missed detection.
