Transmission method and device of false twist compact spinning device and spinning frame

Abstract

The invention discloses a transmission method of a false twist compact spinning device. The false twist compact spinning device adopts a friction belt as a false twisting device, the friction belt iswound around a guide wheel, the axis of the guide wheel is perpendicular to that of a roller, the false twist compact spinning device adopts the front roller as a transmission shaft during transmission, the front roller drives a friction plate of the false twist compact spinning device in a friction manner through a friction ring, the friction ring and the friction plate transmit rotation of the front roller in a right-angled friction transmission manner to drive the guide wheel with the axis perpendicular to that of the front roller in the false twist compact spinning device, the friction belt mounted on the guide wheel in a sleeving manner is rotated along with the rotation of the guide wheel, the friction belt generates the movement relative to the perpendicular direction of fiber strands, and the twisting effect of friction false twist is achieved for the fiber strands between the front roller and a lead-out roller.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a transmission method, a device and a spinning frame of a false twist compact spinning device. Background technique [0002] Long hairiness of yarn is usually a harmful defect of yarn. In order to eliminate hairiness of yarn, patent 201910772187X proposes a false twist compact spinning method of ring spinning, that is, the twisting and untwisting characteristics of false twisting are used to make the fiber hairy The strands can be bundled, untwisted, and re-twisted. Patent 2019108469797 proposes a single-spindle three-wheel belt combined structure false twist compact spinning mechanism and its spinning frame, and proposes a plan for the false twist friction mechanism structure in the compact device. The concentrating mechanism of twist concentrating spinning needs to rely on external transmission to function. As we all know, the space of the twisting and forming part of the s...

[0002] Long hairiness of yarn is usually a harmful defect of yarn. In order to eliminate hairiness of yarn, patent 201910772187X proposes a false twist compact spinning method of ring spinning, that is, the twisting and untwisting characteristics of false twisting are used to make the fiber hairy The strands can be bundled, untwisted, and re-twisted. Patent 2019108469797 proposes a single-spindle three-wheel belt combined structure false twist compact spinning mechanism and its spinning frame, and proposes a plan for the false twist friction mechanism structure in the compact device. The concentrating mechanism of twist concentrating spinning needs to rely on external transmission to function. As we all know, the space of the twisting and forming part of the spinning frame is limited, and the transmission direction of the friction belt of the false twist concentrating mechanism is different from the movement of the drafting mechanism of the existing spinning frame. The direction is not consistent, and the addition of a transmission mechanism will greatly increase the complexity of the equipment mechanism, increase the cost of the equipment, affect the operation, and affect the maintenance and maintenance of the machine. As a new technical solution, false twist compact spinning has every technical problem The link is not only the realizability, but also the practicability of the technical solution. How to use the most concise and simple mechanism in a limited space to solve the transmission of the compacting mechanism of false twist compact spinning is the whole technology of false twist compact spinning. The key to whether the program can be truly practical and industrialized
