A false twist compact spinning device with a rotary disc structure

Abstract

A false twist compact spinning device with a rotary disc structure, the device includes a roller drafting system, a false twist system, a pull-out roller pair and a twisting winding system, and the roller drafting system includes a front roller, a middle roller, The back roller, the false twist system includes a disc runner, the pair of outgoing rollers includes a lower outgoing roller and an upper outgoing roller, and the twisting and winding system includes a spindle, a bobbin, a steel ring, The traveler and the disc runner are located on the output side of the front roller and the feeding side of the lead-out roller. The disc runner is actively rotated by the driving mechanism. The edge of the disc runner contacts the fiber strands, and the friction drives the fiber strands to rotate. False twist is generated, and the false twist point of the fiber strand is on the feeding side of the take-off roller.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a false twist compact spinning device with a rotating disc structure. Background technique [0002] Long hairiness of the yarn is usually a harmful defect of the yarn. In order to eliminate the hairiness of the yarn, the current actual production basically uses air flow to gather the fiber bundles before twisting. In the above two types of methods, the air flow method will generate greater energy consumption, and the mechanical method will cause friction; there is a false twist method in the yarn twisting technology, which is also applied in ring spinning , which uses false twisting technology to apply twists several times higher than normal spinning to the fiber strands output by the front roller, making the spinning twist triangle smaller, eliminating weak twisting, and reducing spinning breakage. The application in ring spinning, its purpose is to realize the low-twist sp...

[0002] Long hairiness of the yarn is usually a harmful defect of the yarn. In order to eliminate the hairiness of the yarn, the current actual production basically uses air flow to gather the fiber bundles before twisting. In the above two types of methods, the air flow method will generate greater energy consumption, and the mechanical method will cause friction; there is a false twist method in the yarn twisting technology, which is also applied in ring spinning , which uses false twisting technology to apply twists several times higher than normal spinning to the fiber strands output by the front roller, making the spinning twist triangle smaller, eliminating weak twisting, and reducing spinning breakage. The application in ring spinning, its purpose is to realize the low-twist spinning and flexible textile production; In the spinning method, one or two pairs of holding rollers are arranged in front of the front roller, and a false torsion tube is set between the front roller and the holding roller. Confinement is concentrated. Compared with the existing technology, this scheme has a complex structure, also requires compressed air energy consumption, and is difficult to control; Fu Jiang, Donghua University’s doctoral thesis proposed a false twister to achieve agglomeration in the spinning frame. Twist concentration spinning method, the technical scheme is to add a set of false twisting device in the drafting area between the apron nip of the drafting mechanism and the front roller to pre-twist the fiber strands so that the fiber strands are Gathering before the output of the front roller, as we all know, adding a false twister between the nip of the apron and the front roller will greatly increase the distance between the nip of the apron and the nip of the front roller, and simultaneously draft and gather fibers in the drafting area , these factors will affect the uniformity of the yarn evenness. So far, how to use the form of twisting to make it a technical means to gather fibers, eliminate hairiness, reduce energy consumption, and be easy to operate remains to be further studied.
