Abstract
The invention relates to a spinning nozzle structure, which comprises a guide device seat (1), a guide device (2), a guide needle (3), a vortex nozzle (4), a gas storage cover (5), a gas exhaust cover (6), a hollow spindle (7) and a vortex support (8). The lower portion of the hollow spindle (7) is connected with the vortex support (8), a vortex pipe (9) is arranged in an end opening at the lower portion of the hollow spindle (7), and a twisting small hole (41) is arranged at the upper portion of the vortex nozzle (4). The novel spinning nozzle structure is characterized in that the distance between an inlet of the twisting small hole and an inlet of the guide device seat is two fifths of the average fiber length, the distance between the inlet of the twisting small hole and the inlet of the vortex pipe is 0.5-2mm, and three to five guide small holes (71) with angles of 15 degrees to 18 degrees are evenly arranged on a cylindrical face of the hollow spindle. The novel spinning nozzle structure effectively improves processing precision of the nozzle and spinning adaptability of spinning varieties, and high quality yarns with few yarn faults are obtained.
Description
Technical field
The present invention relates to a kind of spinning jet nozzle, relate in particular to and a kind ofly can effectively reduce the fall device of fine rate of vortex spinning.Belong to field of textile machinery.
Background technology
Air-flow is widely used in textile processing field at present.In spinning process normal adopt air-flow to fiber carry, condense, the operation such as twisting.But air-flow is strong to the control of fiber not as machinery to the control of fiber, and under action of high-speed airflow, the part fiber will break away from the control of air-flow, discharge with air-flow, form the fibre that falls, and cause raw-material utilization rate greatly to reduce, thereby increases the yarn production cost.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of in the air-flow twisting process, the novel spinning nozzle arrangements that the fine rate that falls is lower.
The object of the present invention is achieved like this: a kind of spinning jet nozzle structure, it comprises the guide seat, guide, guide needle, eddy current spraying nozzle, storage cover, hood, hollow spindle and eddy current support, described guide is installed in the guide seat, the top of described eddy current spraying nozzle not only links to each other with guide but also links to each other with storage cover, the bottom links to each other with hood, insert in the eddy current spraying nozzle on the top of described hollow spindle, its underpart links to each other with hood, the bottom of described hollow spindle links to each other with the eddy current support, in the port of its underpart, be provided with vortex tube, described guide needle is arranged in the guide, be provided with the twisting aperture on the top of described eddy current spraying nozzle, the entrance of described twisting aperture is 2/5ths of average fiber length to the entrance distance of guide seat, and the entrance of twisting aperture is 0.5-2mm to the entrance of vortex tube distance, evenly is provided with individual angle and is 15 °-18 ° guiding aperture on the taper seat of described hollow spindle.
The bottom periphery of described guide seat is provided with sealing ring I, is provided with sealing ring II in crossette periphery, the middle part of described eddy current spraying nozzle.
Compared with prior art, the invention has the beneficial effects as follows:
Effective Raise nozzle machining accuracy of the present invention and Spinning Varieties spinning suiting obtain the few high-quality yarn of yarn defect.
