Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a double-layer suction nozzle of a winding machine with a positive and negative return air duct structure. Background Art

[0002] As a special equipment in the textile industry, the automatic winding machine is used for the last process of spinning and weaving. It connects the head and tail through air twisting, and connects the tube yarn with smaller capacity to form a yarn tube of about 100,000 to 200,000 meters. At the same time, it removes defects on the yarn during the winding process to improve the yarn quality. The completed yarn tube is removed for use on the loom in the next process.

[0003] At present, in the prior art, a Chinese patent with a publication number of CN203794332U discloses a double-layer suction nozzle of a winding machine with a positive and negative return air duct structure. The device automatically recovers the spandex core-spun yarn stuck at the suction nozzle mouth by having positive pressure blowing and negative pressure suction and positive pressure nozzle and negative pressure suction nozzle, thereby increasing the probability of the spandex core-spun yarn twisting into finished products, reducing or even eliminating the spandex core-spun yarn breaking and headlessness. At the same time, the device is easy to install and can be replaced at any time. However, when the device is actually used, the connecting pipe of the suction nozzle device is fixed by bolts when connected to the wire tube, but lacks positioning, which increases the installation time. In view of this, we propose a double-layer suction nozzle of a winding machine with a positive and negative return air duct structure. Utility Model Content
