Technical Field

[0001] The utility model relates to the technical field of temperature monitoring of winding equipment, in particular to a temperature alarm with a doffing protection structure. Background Art

[0002] Winders are specialized equipment in the textile industry, serving as a bridge between the spinning process and the weaving process. Their primary function is to wind the bobbins into knot-free cones and remove yarn defects during the winding process, thereby improving yarn quality and subsequent weaving efficiency. While the winder is operating, its operating temperature must be constantly monitored. Temperature alarms are crucial for reducing the risk of fire. During operation, yarn falling from the winder accumulates on the surface of the temperature alarm, affecting temperature detection accuracy and requiring improvement. Therefore, we propose a temperature alarm with a doffing protection structure. Utility Model Content
