Dual feed carding mechanism

Abstract

The invention relates to a dual feed carding mechanism, in particular to a dual feed carding mechanism of a rotor spinning machine. The dual feed carding mechanism comprises two independent feeding devices, two independent carding devices and two channels. The left and right feeding devices are arrayed symmetrically; the left and right carding devices are arrayed symmetrically, and left and right carding rollers, as the main components, are respectively arranged in left and right carding cavities; the left and right channels are respectively communicated with the left and right carding devices. According to the dual feed carding mechanism, features of a feeding carding mechanism of a traditional rotor spinning machine are changed, original single fiber feeding and carding is replaced with dual fiber feeding and carding during rotor spinning, the single fibers entering the rotor are provided with two independent channels, defects of the rotor spinning for blended yarn spinning and novel yarn production are overcome accordingly, using field of the rotor spinning is expanded effectively, and varieties of rotor yarns are enriched.

Description

technical field [0001] The invention belongs to the technical field of spinning machines, and relates to a double-feeding and carding mechanism, in particular to a double-feeding and carding mechanism of a rotor spinning device, in particular to a two-set feeding and carding device Feeding and carding mechanism for rotor spinning machines that are parallel and have two channels. Background technique [0002] With the rapid development of the textile industry and the continuous improvement of the level of automation, various new spinning methods have emerged. Among them, due to its high spinning speed, large package capacity, good spinnability, and the ability to spin high-quality low-grade raw materials and low-grade raw materials, the rotor spinning machine has become the most mature and widely used spinning technology in the new spinning technology. The spinning form with the widest range and high economy. Since it was put into large-scale industrial application in the 1...

AI Technical Summary

Problems solved by technology

Due to the single-set carding characteristics of the traditional spinning device, the rotor spinning has a greater application in cotton spinning products, but at the same time, the rotor spinning is also used to produce blended yarns, short and thick slub yarns, fancy yarns, etc. Larger limitations and problems with new yarns

The main reason is that different types of carding rollers have different application ranges for raw materials, and it is difficult for the same carding device to card fibers with different properties at the same time. Therefore, to a certain extent, it limits the variety of rotor spinning varieties. sex
