A kind of pre-opening device and working method of wool spinning raw material

Abstract

The invention discloses a pre-opening device for wool spinning raw materials, which comprises an installation mechanism for accommodating dyed raw wool, a stirring mechanism for preliminary opening of dyed raw wool, and a device for separating large fiber clusters of dyed raw wool after preliminary opening. Thread-splitting mechanism, the thread-drawing mechanism that transports the dyed raw wool from the stirring mechanism to the thread-splitting mechanism; the stirring mechanism includes two stirring motors arranged symmetrically up and down, and a cloth strip is connected between the output ends of the two stirring motors, and the cloth strip is fixed There are multiple hollow balls; the installation mechanism includes an opening box that accommodates the hollow balls and the dyed raw wool; the branching mechanism includes a branching box that is in a negative pressure state relative to the opening box, and a vibrating main shaft is installed inside the branching box. The top and the bottom are respectively connected with a plurality of up-and-down symmetrical lead rods; a working method of the pre-opening device for wool spinning raw materials, including S1 equipment inspection; S2 wool loading and ventilation; S3 preliminary stirring and opening; S4 air extraction and further opening ; S5 draws the line; S6 divides the line; S7 draws the line.

Description

technical field [0001] The invention relates to the field of garment production, in particular to a pre-opening device for wool spinning raw materials and a working method of the pre-opening device for wool spinning raw materials. Background technique [0002] Wool spinning is a spinning process in which wool fibers are processed into yarns. The raw material wool fibers are mainly wool, and also include special animal hairs such as cashmere, rabbit hair, mohair, and yak hair. The wool spinning process can also be used for wool-type chemical fiber pure spinning, blending and blending with other natural fibers. The fabrics obtained from woolen fabrics have a wide range of applications. Woolen fabrics, knitted fabrics, blankets, etc. woven with pure and blended woolen yarns have the characteristics of warmth retention, moisture absorption, elasticity and wear resistance. Clothes made of woolen fabrics feel soft and moist. , plump and shaved. Opening is the process of breaking...

AI Technical Summary

Problems solved by technology

If the fiber clusters are formed from the beginning to the end without opening, the following problems will occur in descending order of severity: 1. During the sliver making, because the large fiber clusters are too tightly bonded, the fiber clusters in some positions are closely connected. The fiber clusters in some positions are weak, which makes it impossible to produce good sliver diameters during sliver making. In the sliver production, large fiber clusters appear segment by segment, and the parts of the sliver are knotted, and cannot withstand the force Pulling, easy to break; second, the problems that occur during the sliver making will lead to spinning failure, not getting good yarn or even yarn breakage during spinning; third, the finished product obtained by weaving will lose some characteristics, such as softness , bulkiness and aesthetics

[0004] In the invention with the publication number CN201810605684.6, a woolen fabric pre-opening mechanism is disclosed. During the wool spinning process, the raw wool is spread and then opened. The opening effect of this opening method is poor and the efficiency is low; A utility model with the publication number CN201520105512.4 discloses an impurity removal device for a net wool opener. This utility model uses hot air and a grille for opening, but also has the problems of low opening efficiency and poor opening effect.
