Problems solved by technology

[0004] In short, no matter what kind of carding method in the current equipment, it is impossible to effectively separate the long and short fibers from the thick and thin fibers in the sliver, resulting in poor spinnability of the sliver, low spinning count, poor yarn quality, low fiber utilization rate, and high production costs.

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, the combing and sorting device of the present invention has a similar structure with the existing combing machine, and also includes a feeding mechanism, a nipper mechanism, a carding mechanism, a pulling and separating mechanism, a sliver delivery mechanism, and a cleaning mechanism. At present, the combing machine is a front-swing, intermittent straight-type combing machine. The main working characteristics are: the carding is carried out intermittently and periodically, the position of the nipper mechanism and the carding mechanism does not move, and the pulling car swings back and forth to complete Segmented and directional combing of fibers to remove grains and weeds.

[0026] The feeding mechanism comprises a feeding frame 1, and the lower part of the feeding frame 1 is provided with a plurality of hemp sliver ...

Abstract

The invention relates to a method and device for combing and sorting hemp fibers. Combed hemp slivers of different specifications and lengths are obtained through multi-passes of combing. The length can be changed by adjusting the pulley. In the carding mechanism of the device of the present invention, the circular combs are arranged in the range of 0 to 270°, and are divided into a rack type and a combined rack and needle row type, and the top combs are divided into a single-row type and a multi-row type. The pulling and separating mechanism includes a pulling car, which is installed on an adjusting frame, and the adjusting frame is provided with a lever and an arc-shaped chute, and bolts are inserted in the arc-shaped chute, and the bolts are fastened to the frame. Loosen the bolt and pull the lever to make the adjustment frame slide along the arc-shaped chute. At least two pairs of crimping rollers are arranged in the delivery mechanism. The hemp sliver processed by the method and device of the invention has uniform dryness, low short-lint rate, uniform fiber length, low ultra-long fiber content, more parallel and straight fibers, convenient operation, high efficiency and low labor intensity.

Description

technical field [0001] The invention relates to a hemp fiber processing method and device, in particular to a hemp fiber combing and sorting method and device. Background technique [0002] Hemp fibers (except ramie) only account for about 20% in the form of single fibers, and the remaining about 80% are glued together in bast in bundles of 10-40. After the hemp bast is degummed and processed, the hemp fiber used for spinning is composed of these fiber bundles and single fibers of different thicknesses and lengths. Therefore, the length and fineness of hemp fiber are extremely poor. After the hemp spinning is combed and part of the long fibers are extracted, a large number of short fibers and a few ultra-long fibers are left, so that the noil fibers are generally distributed in the range of 5-160mm in length and 1.25-40dtex in thickness, and the long fibers above 65mm are about It is 15%, and short fibers below 16mm often account for more than 30%. [0003] In the existin...
