Dedicated mechanical vertical twister for long strand silk dryer

Abstract

The present invention discloses a kind of mechanical vertical twisting device specially used for filament bar instrument; hollow pipe 1 is connected with pulley 2 through a connecting axle and is conveyed through a leather belt; a motor drives hollow pipe 1 and lead-in yarn rollers 3 separately; the centers of tension adjuster 4 and yarn-guide rod 8 are all on a horizontal line; the right side edge of the yarn-guide rod 8, the center of capacitance plate 6 and the right side edge of yarn-guide rod 9 are all on a vertical line; the lower side edges of pulley 2 and yarn-guide rod 9 are all on horizontal line; the left side edge of the right roller of lead-in yarn rollers 3 and the left side edge of hollow pipe 1 are all on a horizontal line. The invention has resolved the problems of the instability controlled by air currents and unevenness created by volatilization of oil solutions.

Description

technical field [0001] The invention relates to a special part of a textile instrument, in particular to a special mechanical vertical twisting device for a filament evenness meter. Background technique [0002] Chemical fiber filaments are produced by drawing and merging multiple fibers. In order to understand the production quality, a capacitive evenness meter is used to measure the filaments. Chemical fiber filaments generally have no twist or a small twist, which needs to be eliminated by twisting. "Section shape" effect (additional unevenness due to unfixed section). The traditional method is generally to control the rotation and speed of the airflow during measurement to adjust the twist and tension of different numbers of filaments to be measured. The rotation of the airflow makes the measured filament twist into a high-speed filament bundle when passing through the narrow signal plate of the sensor, so that the filament bundle will not spread out of the plate and lo...

Problems solved by technology

However, the above-mentioned measurement method has the problem that it is sometimes difficult to be stable when the airflow is used for multiple measurements. At the same time, it cannot solve the uneven effect caused by the different fiber friction coefficients caused by the uneven volatilization of the oil agent inside and outside the filament package, which makes the measurement data Severe distortion, the same instrument measures the same sample with different storage periods, and the measurement results are inconsistent
