Online detection device for broken end of spinning yarn and spinning machine

Abstract

The invention relates to the technical field of spinning equipment, in particular to an online detection device for a broken end of spinning yarn and a spinning machine. The online detection device comprises a spring compression mechanism and an alarm triggering assembly, the spring compression mechanism is located under the to-be-detected spinning yarn, the alarm triggering assembly includes a conductive convex point mounted on the upper surface of the spring compression mechanism and a conductive piece which is mounted on the upper portion of the spring compression mechanism and matched withthe conductive convex point, the conductive convex point and the conductive piece are connected in series with the two power supply ends of an alarming apparatus through corresponding wires respectively, and when the spring compression mechanism moves upward until the conductive convex point is in contact with the conductive piece for connection, the alarming apparatus performs alarming. The online detection device can achieve online detection of the produced spinning yarn, and misjudgment and detection missing situations generated when the broken end of the spinning yarn is detected according to the thread tension of the spinning yarn are avoided.

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.
