Fiber mixing method and device

Abstract

The invention discloses a fiber mixing method and a fiber mixing device. The fiber mixing method comprises the following steps: firstly, selecting n fiber raw materials as number 1 fiber raw material to number n fiber raw material, wherein n is more than or equal to 2; secondly, carrying out opening and carding on the fiber raw materials at the same time respectively to form continuous and stable cotton-storage quantity, then respectively outputting at an output speed corresponding to the set raw material component proportion, and then respectively carrying out fine carding and opening to correspondingly form the fine fiber bundles from number 1 fiber raw material to number n fiber raw material; and finally, uniformly gathering and mixing the fine fiber bundles of the fiber raw materials through air flow carrying to form mixed fiber bundles. The fiber mixing device comprises an elementary carding-opening set, a conveyor fan set, a pneumatic control cotton-case set, a fine opening machine set and a mixer. The invention can realize the colorless difference in the whole mixing process, directly carry out the carding procedure without scotching, and can realize the strip forming by a single fiber for fulfilling the aims of reducing fiber damage, saving labor and reducing power consumption.

Description

technical field [0001] This group of inventions relates to the mixing method and equipment of multi-fiber and multi-color according to various set ratios in the textile color spinning industry and semi-worsted spinning industry, such as the multi-ratio mixing of different types of fibers, the same kind of but different colors of fibers Mixing methods and equipment for various proportions of different types of fibers and different proportions of fibers of different colors. Background technique [0002] At present, in the domestic color spinning and semi-worsted spinning enterprises, there are three forms for the mixing of fibers of different colors in the front process. One is to use the pre-spinning process of cotton spinning. The equipment used includes disc grabber (FA002), cotton opener (FA106), multi-bin (FA025) and baler; this process uses disc feeding, and each disc The weight is about 1 ton. Due to the difference in raw material density at the head and tail of the di...

AI Technical Summary

Problems solved by technology

The principle of the process flow is to mix each fiber according to the proportion and color requirements, after weighing by the weighing cotton feeding machine, each raw material component falls on the cotton feeding conveying curtain layer by layer, and then moves with the conveying curtain At the feeding port of the blending machine, since several fiber components are fed into the blending machine together, they play the role of horizontal laying and straight picking, so fibers of different colors can be mixed, but this process still exists chromatic aberration

The main manifestations are: in this process, each fiber is accurately measured and weighed when it is fed according to the proportion and color, but the weighed fiber falls on the cotton feeding conveyor curtain in a free fall motion, so it cannot be guaranteed to fall on the conveying curtain. The area of ​​each layer of fibers on the curtain at the overlapping place is consistent from top to bottom, and the thickness of each layer of fiber is also different in height, so the different instantaneous component contents and The colors are different, which will eventually cause color difference in the subsequent production

Looking at the above process, first of all, due to the inability to solve the problem of accurate feeding and precise mixing control of each fiber component, the color difference in actual production is caused; secondly, the fiber raw materials of different colors and multi-proportions after the above process are mixed, in order to To further reduce the color difference, either through baling and then through the cleaning process such as flower grasping machine, cotton blending machine, coiling, etc., or through Qinggang United to make slivers and finally flow into the subsequent process. The cleaning process cannot be omitted and directly entered The carding machine produces raw sliver; thirdly, due to the hidden danger of color difference left by the previous mixing process, the color difference problem must be compensated by increasing the number of draw frames and merging times to achieve the purpose of improving the color difference, instead of using a single-section draw frame Realize the drawing frame process, because the process flow is too long, the labor cost and power consumption are increased, the fiber is damaged, and the spinning performance of the fiber is reduced
