Abstract

The invention discloses a focused spinning method with a variable draw ratio. According to the method, a speed reduction box is arranged on one side of a front roller; a transmission shaft is arranged at an output end of the speed reduction box; an input end of the speed reduction box is driven through the front roller or a servo motor; when the front roller is adopted for driving, the front roller and the input end of the speed reduction box are connected through a belt pulley mechanism; when the servo motor is adopted for driving, the servo motor is directly connected with the input end of the speed reduction box; the transmission shaft is driven by the speed reduction box; a carrier gear is arranged on the transmission shaft; the transmission shaft drives the carrier gear to spin in a focused manner. The focused spinning method with the variable draw ratio, which is disclosed by the invention, adopts the servo motor or front roller to drive the transmission shaft, the draw ratio is adjusted through the servo motor or by changing the transmission ratio of the speed reduction box to the belt pulley mechanism, the front roller of a spinning frame does not need to replace, the transformation cost is saved, and the spinning quality of a yarn is ensured.

Description

technical field [0001] The invention relates to a spinning method, in particular to a compact spinning method with variable draft ratio. It belongs to the technical field of spinning. Background technique [0002] Compact spinning is to add a set of negative pressure compact spinning device under the front and bottom of the drafting front roller of the original traditional ring spinning, so that the width of the sliver after drafting is narrowed, thereby reducing the spinning triangle area of ​​ring spinning and obtaining A yarn with smooth surface, less hairiness, high tenacity and excellent evenness. The traditional four-roller compact spinning is to replace the front roller of the original ring spinning frame with a toothed front roller, add a bridge gear assembly under the collecting tube, and the toothed front roller drives the compact roller through the bridge gear transmission. yarn method. Once the draft ratio of the spinning device of this structure is determined...
