Abstract

The invention relates to a circular weft knitting machine broken needle detection mechanism. The circular weft knitting machine broken needle detection mechanism is arranged on a triangle of a saddle and comprises a pin arranged on the triangle, a swinging piece rotatably arranged at the free end of the pin, a sensor arranged on the saddle and a reset spring arranged on the saddle, the free end of the reset spring is connected with the swinging piece which is arranged in the triangle and located on the lower potion of a needle butt of a knitting needle, when the knitting needle move up and down, the needle butt can make contact with the swinging piece and press the swinging piece to rotate, and when the swinging piece swings, the sensor can be triggered.

Description

technical field [0001] The invention relates to a broken needle detecting mechanism of a circular knitting machine. Background technique [0002] Circular knitting machines contain a large number of needles, which may break easily if subjected to a certain degree of wear. Circular knitting machines are often used in high-volume continuous production. If the needles break, defects are caused in the produced fabric, resulting in rejects. Knitting needle breakage may occur again and again without warning and unforeseen. Therefore, monitoring the needles of the running knitting machine, that is, broken needle detection, is an indispensable and important part of it, which is very important for improving product quality and reducing defects It plays a vital role with defective products. [0003] The existing grating broken needle detection device in the market is affected by environmental light interference or cotton flying debris pollution detection lens and other reasons duri...
