Embodiment Construction

[0022] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0023] Such as figure 1 As shown, a vortex tube internal structure provided by the present invention is a three-stage air-jet vortex spinning nozzle device, which includes a guide body 1, a vortex tube 2, a cone body 3, a yarn guiding tube 4 and a fixed housing bracket 5. The guide body 1 and the vortex tube 2 are installed in the front copper cover 6 through screws 28 to form the first part of the nozzle, and the conical body 3 and yarn drawing tube 4 are installed in the rear end copper cover 7 through the screws 28 to form the second part of the nozzle. The first part of the nozzle and the second part of the nozzle are separated. When spinning, the two are assembled into one by fixing the housing bracket 5, and the fiber inlet 12 of the conical body 3 of the vortex chamber 13 is connected to the fiber inlet 12 after assembly. ...

Abstract

The invention adopts the technical scheme that an air-jet vortex spinning nozzle device with a vortex tube having a three-sectional interior structure is provided. The device comprises a guide body, the vortex tube, a cone body, a doffing tube and a fixed casing bracket, wherein the guide body and the vortex tube are arranged in a front copper cover in a matched way to form a first nozzle, the cone body and the doffing tube are arranged in a rear copper cover in a matched way to form a second nozzle, and the first nozzle and the second nozzle are assembled in the fixed casing bracket. The device is characterized in that the interior of the vortex tube is designed into the three-sectional structure, one end opening of an air-jet hole of the vortex tube is formed in the outer circumference of the vortex tube, and the other end opening of the air-jet hole is formed at the connecting part of the first section and the second section. Sufficient space is arranged in the vortex tube, so that air can more stably rotate. Besides, no air tends to return to the first section. The strength of air-jet vortex spun yarns can be obviously improved.

Description

technical field [0001] The invention relates to an air-jet vortex spinning nozzle device with a three-stage inner structure of a vortex tube. Background technique [0002] The internal structure of the vortex tube of the existing air-jet vortex spinning nozzle device is two-stage, and the air injection hole is punched on the first section of the internal structure, which makes the air flow rotation unstable, the operating space is reduced, and a small part of the air flow is directional to the nozzle. The tendency of inlet backflow causes the feeding of fiber bundles to be affected to a certain extent. Contents of the invention [0003] The object of the present invention is to provide an air-jet vortex spinning nozzle device which has no backflow of air flow and improves the strength of the air-jet vortex spinning yarn. [0004] In order to achieve the above object, the technical solution of the present invention is to provide a three-stage air-jet vortex spinning nozzle...
