Description

A kind of spiral collection surface bleeder rotor

Technical field

The utility model belongs to spinning equipment field, relates to rotor spinning machine, is specifically related to a kind of spiral collection surface bleeder rotor.

Background technology

In spinning method, rotor spinning, because of its technology maturation, good in economic efficiency, has become application surface a kind of spinning system very widely.Due to unique Spinning Principle be different from the equipment mechanism of ring spinning completely, rotor spinning has obvious advantage: rotating speed is high, output is large, can be up to 150,000 revs/min, and package capacity is large, and technological process is simple, and the many and cost of spinning suiting raw material is lower etc.

Rotor, as the vitals of rotor spinning machine, has significant impact to the quality of yarn.Bleeder rotor on existing rotor spinning machine strips in the process of cohesion yarn at revolution sliver, can ride fiber at pick-up point and the generation of yarn tail end.In spinning process, the head end that rides fiber is with the reach of revolution sliver, and tail end rotates with cup, and after riding the head end of fiber and peeling off, its tail end is extracted out from cohesion yarn, is wrapped in sliver surface, becomes winding fiber.Be wound around fiber and oppositely, be irregularly wound in sliver surface, its fiber strength can not make full use of, thereby affects outward appearance and the intensity of Rotor yarn.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, a kind of spiral collection surface bleeder rotor is provided, and this bleeder rotor can suppress to be wound around the generation of fiber effectively, increases the aesthetics of Rotor yarn, strengthen the intensity of Rotor yarn, improve the quality of yarn.

The utility model comprises cup and the cup of one-body molded and coaxial setting, and cup is arranged on the bottom of cup; Described cup entirety is for offering the cylindrical of through hole along axle center; Described cup comprises upper cup, middle part cup and bottom cup; Upper cup is the truncated cone-shaped of just putting, and middle part cup is cylindrical, and bottom cup is inverted truncated cone-shaped, and the upper and lower edge of middle part cup joins with upper cup and bottom cup respectively; Described upper cup, middle part cup and bottom cup enclose the cavity consistent with cup outer wall shape; The open-top setting of described cavity, the through hole of bottom and cup connects; The inwall of described middle part cup is processed with cohesion screw thread, forms annular collection surface.

Described cohesion thread type is regular screw threads, trapezoidal thread, saw-tooth thread, gas thread or taper thread, and pitch is 2～5mm, reach is pitch 1～2 times.

The beneficial effects of the utility model:

The utility model is by the optimal design to rotor collection surface, at the sidewall processing cohesion screw thread of collection surface, can effectively cohesion yarn pick-up point be separated with cohesion yarn tail end, elimination rides the formation condition of fiber, thereby effectively reduce the formation that rides fiber, suppress to be wound around the generation of fiber, increase the aesthetics of Rotor yarn, strengthen the intensity of Rotor yarn, improve the quality of yarn.

Fig. 3 is the form schematic diagram that condenses yarn in existing bleeder rotor.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, a kind of spiral collection surface bleeder rotor comprises cup 1 and the cup of one-body molded and coaxial setting, and cup 1 is arranged on the bottom of cup; Cup 1 entirety is for offering the cylindrical of through hole along axle center; Cup comprises upper cup 2, middle part cup 3 and bottom cup 4; The truncated cone-shaped of upper cup 2 for just putting, middle part cup 3 is cylindrical, bottom cup 4 is inverted truncated cone-shaped; The upper and lower edge of middle part cup 3 joins with upper cup 2 and bottom cup 4 respectively; Upper cup 2, middle part cup 3 and bottom cup 4 enclose the cavity 5 consistent with cup outer wall shape; The open-top setting of cavity 5, the through hole of bottom and cup 1 connects; The inwall of middle part cup 3 is processed with cohesion screw thread, forms annular collection surface 6.The thread type of cohesion screw thread is regular screw threads, and pitch is 2mm, and reach is 3mm.

As illustrated in fig. 1 and 2, fiber enters cohesion in the collection surface 6 of cup, twisting, and the cohesion yarn 7 of formation is arranged in the shape of a spiral along cohesion screw thread in collection surface 6; At cohesion run-out(of thread), the head end of cohesion yarn is pick-up point 8, and revolution sliver 9 strips the head end of cohesion yarn 7, it is peeled off at pick-up point 8, and grip output by delivery roller 10.

This spiral collection surface bleeder rotor is by the optimal design to rotor collection surface, at the sidewall processing cohesion screw thread of collection surface 6, can effectively cohesion yarn pick-up point be separated with cohesion yarn 7 tail ends, elimination rides the formation condition of fiber, thereby effectively reduce the formation that rides fiber, suppress to be wound around the generation of fiber, increase the aesthetics of Rotor yarn, strengthen the intensity of Rotor yarn, improve the quality of yarn.

As shown in Figure 3, existing bleeder rotor strips in the process of cohesion yarn 7 at revolution sliver 9, space between pick-up point 8 and cohesion yarn 7 tail ends can be filled up by a small amount of fiber, and the two ends of these fibers straddle respectively on the tail end and pick-up point 8 of cohesion yarn 7, form and ride fiber 11.In spinning process, ride fiber 11 and can be wrapped in sliver surface, become winding fiber, be wound around fiber and oppositely, be irregularly wound in sliver surface, its fiber strength can not make full use of, thereby affects outward appearance and the intensity of Rotor yarn.
