A precision skein overfeed roller

Abstract

The invention discloses a precision skein over-feed roller, comprising a skein seat plate, a driving wheel, a separating wheel and a ceramic pass wheel. The skein seat plate is provided with a flange which comprises an adjusting flange and a fine adjusting flange; the adjusting flange is connected with an auto-feed preventer; the auto-feed preventer comprises a ceramic separating wheel and a ceramic separating wheel handle; the ceramic separating wheel is fixed to the adjusting flange; the ceramic separating wheel handle is connected to the ceramic separating wheel; the ceramic separating wheel mutually fits the driving wheel; the fine adjusting wheel is connected with a fine adjusting device; the fine adjusting device comprises a ceramic ring and a locking tooth; the ceramic ring is fixed to the fine adjusting flange; the ceramic ring mutually fits the driving wheel; the locking tooth is fixed to the skein seat plate and used for acting on the driving wheel. By mounting the precision skein over-feed roller on a two-for-one twister, the error of soft package yarns can be controlled within 0.02g / cm<3>, the lowest density reaches 0.33g / cm<3>, the problem that the existing over-feed roller has the density control difficulty is solved, and the novel process can be put in practice in production.

Description

technical field [0001] The invention relates to an overfeeding roller structure of a two-for-one twister, in particular to an overfeeding roller for precision skeined yarn. Background technique [0002] The traditional yarn dyeing process is mainly two-for-one twisted yarn—yarn skein—dyeing—skein winding, and the loss is serious in the two processes of yarn skein and skein winding. The new process is mainly two-for-one twisted loose yarn-dyeing, which saves the two processes of yarn skeining and skein winding, thereby greatly saving costs. According to the actual production data, the new process dyeing yarn can save about 50%, but the density of the loose yarn made by the equipment on the market is inconsistent, the difference is relatively large, generally 0.36g / cm 3 ~0.43g / cm 3 Can not meet the requirements of high-quality yarn dyeing. At present, the density of loose yarn must be controlled at 0.35g / cm 3 ~0.37g / cm 3 Between, existing overfeeding roller is difficult t...

[0002] The traditional yarn dyeing process is mainly two-for-one twisted yarn-yarn skein-dyeing-skein winding, and the loss is serious in the two processes of yarn skein and skein winding

The new process is mainly two-for-one twisted loose yarn-dyeing, which saves the two processes of yarn skeining and skein winding, thereby greatly saving costs. According to the actual production data, the new process dyeing yarn can save about 50%, but the density of the loose yarn made by the equipment on the market is inconsistent, the difference is relatively large, generally 0.36g / cm 3 ~0.43g / cm 3 Cannot meet the requirements of high-quality yarn dyeing

At present, the density of loose yarn must be controlled at 0.35g / cm 3 ~0.37g / cm 3 In between, it is difficult for the existing overfeeding roller to control the density of the loose yarn within the above range, so it is impossible to implement the new process into production
