Multi-roving feeding spinning device and spinning method

Abstract

A multi-rove feeding spinning device and spinning method, which introduce a four-roller drafting and multi-rove feeding method into the production system, lay the foundation for further enriching the appearance style of the yarn. The characteristics of the device are: the drafting system adopts four rollers, and the four rollers are controlled by separate servo motors, the yarn winding is controlled separately by the winding servo control motor, and five high-precision servo motors are respectively connected to the programmable logic controller ; The roving adopts the following feeding method: the first roving is fed to the bell mouth at the front of the rear roller, and the first roving is fed to the rear roller through the first roving feeding bell mouth, and the middle rear roller, the middle front roller and the front roller The upper part of the roller is respectively equipped with the second, third and fourth roving feeding bell mouth, and the second, third roving system and fourth filament are respectively fed by the second, third and fourth roving feeding bell mouth.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a multi-roving feeding spinning device and spinning method. Background technique [0002] The drafting system is an important part of the spinning frame, and its performance directly affects the yarn quality. At present, the common spinning frame adopts the three-roller drafting form, including the common three-roller double-apron structure and the three-roller four-apron structure that can achieve 80-100 times larger draft. The ordinary three-roller double-apron structure is divided into two drafting areas: the front drafting area and the rear drafting area, and the rear area only uses simple rollers for drafting, so the friction force circle in the middle is relatively weak, and the draft ratio is generally less than 1.4 times, which is unfavorable to increase the total draft ratio of the spinning frame, so the total draft ratio is between 20 and 50. In order to solve the pr...

Problems solved by technology

The modification cost of this method is lower and the efficiency is higher, but the evenness of yarn dryness is poor

In view of this, in the Chinese patent "Segment Color Spinning Transmission Device (Patent No.: ZL200420081737.2)", a segment color yarn production device with four loops is provided, but this device still uses double roving feeding, and at the same time , the first roller and the second roller are still controlled by the same motor, so the main draft cannot be adjusted freely
