Sesaron combing and sorting method and device

Abstract

The invention relates to a sesaron combing and sorting method and a device; combed ramie stripes with different specifications and lengths are obtained through a plurality of layers of combing; the split degree of the ramie stripes is decided by comb needle models used in all the layers of combing; and the lengths of the ramie stripes are changed by adjusting a pulling vehicle. In a combing and sorting mechanism of the device, circular comb needle strips are lined in a circumference of 0 to 270 degrees respectively through a rack method and a rack and needle row combined method, and top combs are in a single row or a plurality of rows. A pulling separation mechanism comprises the pulling vehicle, the pulling vehicle is arranged on a regulation frame, the regulation frame is provided with a rod and a circular arc-shaped chute, a bolt is inserted into the circular arc-shaped chute, the bolt is fastened on a frame, the bolt is loosened, and the regulation frame can slide along the circular arc-shaped chute by triggering the rod. At least two pairs of curl rollers are arranged in a strip discharge mechanism. The ramie stripe fibers processed by the method and the device are even and uniform, have short fiber rate, uniform fiber length and low ultra-long length fiber content, so that the fibers are more parallel and straighter, the operation is convenient, the efficiency is high, and the labor intensity is low.

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%.

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.
