Cotton carding method and device

Abstract

The invention relates to a cotton carding method and device and particularly relates to a short-flow yarn spinning method and device for outputting a plurality of cotton strips of a single cotton carding machine. The cotton carding method provided by the invention adopts a method for carding cotton by regions, forming a fiber net by regions and forming strips by regions, so that a novel yarn spinning technology that the plurality of cotton strips can be output by the single cotton carding machine, and the cotton strips are used as raw materials when plurality of cotton strips are fed into a rotary cup yarn spinning machine or a vortex yarn spinning machine and the like online is realized. The online connection of carding cotton and fine yarns is realized, and storage and transportation of the cotton strips are saved, so that the production efficiency is improved. A self-adjustable leveling device is additionally arranged between the cotton carding device and a spinning frame, and is used for adjusting the non-uniform weight of the cotton strips. In order to solve the problems that the strength of the cotton strips is relatively low, and the cotton strips can be easily and accidentally stretched when the cotton strips are operated under the condition of bearing tension so that the weight of the cotton strips is not uniform, a false twisting device is further additionally arranged, and certain false twisting is applied to the cotton strips output by the self-adjustable leveling device, so that the strength of the cotton strips between the self-adjustable leveling device and the spinning frame is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of spinning, and relates to a carding method and a device thereof, as well as a spinning method and a spinning machine, in particular to a short-flow spinning method and a device thereof for outputting multiple slivers from a single carding machine. Background technique [0002] The function of spinning is to spin random short fibers into continuous yarns. The traditional spinning process includes four processes: opening and cleaning, carding, drawing and spinning. This process has the disadvantages of long process, large floor area and low economic benefit. Shortening the spinning process is of great significance for improving spinning production efficiency, reducing labor costs and improving the automation level of textile processing equipment. [0003] Compared with the ring spinning system, rotor spinning and eddy current spinning, which use cotton sliver as raw material, have obvious advantages in sho...

AI Technical Summary

Problems solved by technology

The invention utilizes the self-designed short-flow spinning system without drawing frame autolevelling, realizes one machine with multiple carding machines, solves the problem of mismatching production speed between traditional carding machines and spinning machines, and realizes cleaning and carding The direct connection with the spinning machine eliminates the drawing process, shortens the spinning process, improves production efficiency, saves labor, and can greatly improve economic benefits. At the same time, the self-designed carding machine is used to realize single carding. The multi-head spinning device is supplied online by the machine, and an autoleveling device is added between the carding machine and the spinning machine, which can adjust the uneven weight of the yarn online and produce a certain quality of spun yarn
