Description

Technical Field

[0001] The utility model relates to the technical field of yarn guides, in particular to a yarn guide device for a seamless knitting underwear machine with a yarn breakage detection function. Background Art

[0002] In the production of seamless knitted underwear, the continuous and stable flow of yarn directly impacts product quality and production efficiency. Traditional yarn guides typically rely on manual inspections or electronic sensors (such as photoelectric and capacitive) to detect yarn breaks. These sensors suffer from the following drawbacks: Electronic sensors are susceptible to interference from the workshop environment (such as flying catkins and oil stains), leading to false or missed alarms. Consequently, yarn breaks fail to trigger an alarm immediately, resulting in fabric defects. Independent detection modules require additional wiring and control circuitry, increasing maintenance costs and installation complexity.

[0003] Manual inspection not only increases labor costs, but is also prone to missed inspections and cannot accurately detect yarn breakage, affecting product production quality. Utility Model Content
