Embodiment Construction

[0027] figure 1 The illustrated spinning nozzle 1 according to the invention is fixed in a known manner in a shroud 2 of a rotor housing, not shown here. Yarn drawing mouth 1 is used for guiding the yarn 5 made on the spinning rotor 4 to make it turn around, and here the yarn is represented by a dotted line. Wherein, the rotational speed of the spinning rotor 4 reaches up to 150,000 revolutions per minute, and the drawing speed of the finished yarn 5 is, for example, 250 m / min. When the rotor 4 rotates, the yarn 5 is moved around the surface of the yarn drawing mouth 1 in the manner of crank transmission.

[0028] In this embodiment, the yarn drawing nozzle 1 is composed of the yarn drawing nozzle funnel 6 and the yarn drawing nozzle shaft 7, the yarn 5 turns on the yarn drawing nozzle funnel, and the yarn drawing nozzle shaft is used to fix the yarn drawing nozzle 1 on the shield of the spinning device 2 within. Due to the uninterrupted contact with the high-speed circular...

Abstract

A yarn draw nozzle (1) for an air spinning device, having a yarn draw nozzle funnel (6) for diverting a finished yarn (5) during the yarn draw process, said yarn draw nozzle funnel containing a yarn Turning area (3). The yarn drawing nozzle funnel (6) specifically comprises two parts, that is, an outer part (6a) containing the first region (3a) of the yarn diversion area (3) and an outer part (6a) comprising the yarn diversion area (3) The inner part (6b) of the second area (3b) of the. The two parts (6a, 6b) consist of different materials and / or are provided with different coatings at least in the region (3a, 3b) of the yarn deflection zone (3), or the two parts (6a, In 6b) only one of the parts has a coating.

Description

technical field [0001] The invention relates to a yarn draw nozzle for an air spinning device, the yarn draw nozzle comprising a yarn draw nozzle funnel for deflecting a finished yarn during the yarn draw process, the yarn draw nozzle funnel containing a yarn deflection zone. Background technique [0002] There are various yarn drawing nozzles for air spinning machines in the prior art. These yarn drawing nozzles are fixed in the yarn drawing channel of the air spinning device, and are used for guiding and turning the yarn made on the spinning rotor during the yarn drawing process. The yarn drawing nozzle is in continuous contact with the yarn it draws during the working process, which will cause the yarn drawing nozzle to heat up severely, especially when the rotor rotates at a high speed and the yarn drawing speed is high. If the heat cannot be effectively dissipated, the high temperature generated by this part of the heat will damage the yarn, resulting in yarn breakage,...
