Abstract

The invention provides a nozzle block, an air spinning device and an air spinning machine. The nozzle block includes a body portion (111) having a swirl chamber (117) and a spinning nozzle (123). A spinning nozzle (123) includes a straight portion (151) and a section changing portion (153). The straight portion (151) has an ejection port (125) which is located at one end of the nozzle in the axial direction and faces the swirl chamber (117), and extends in an axial direction of the spinning nozzle (123). The section changing portion (153) is connected to the straight portion (151) on the side opposite to the ejection port (125) in the axial direction of the spinning nozzle (123). The diameter of the section changing portion (153) increases from a connecting portion (155) between the straight portion (151) and the section changing portion (153) toward the other end in the axial direction of the spinning nozzle (123). A length (L2) of the straight portion (151) in an axial direction of the spinning nozzle (123) is equal to or larger than 0.4 and equal to or smaller than 4. The opening angle (theta) of the section changing portion (153) is above 5 degrees and below 90 degree.

Description

technical field [0001] The invention relates to a nozzle block, an air spinning device and an air spinning machine. Background technique [0002] Conventionally, there is known a nozzle block that is applied to an air spinning device that applies a swirling airflow to a fiber bundle to generate a yarn in an air spinning machine. Patent Document 1 and Patent Document 2 disclose such a nozzle block. [0003] In the structure of Japanese Patent Application Laid-Open No. 6-10372 (Patent Document 1), the spinning device is composed of a nozzle block, a guide member support, and a rotating spindle. In this spinning device, the portion of the nozzle block that covers the vicinity of the entrance of the hollow guide shaft serves as a hollow chamber. Nozzles are formed on the nozzle block. After the compressed air flows into the air storage part, the compressed air is ejected from the nozzle into the hollow chamber, thereby generating a high-speed swirling airflow near the entranc...
