Precision skein over-feed 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 a precision hank yarn overfeeding roller. Background technique [0002] The traditional yarn dyeing process is mainly two-for-one twisting yarn-yarn skeining-dyeing-skein winding, and the loss is serious in the two processes of yarn skewing and skein winding. The new process is mainly double-twisted loose cone yarn-dyeing, which saves the two processes of yarn skeining and skein winding, which greatly saves costs. According to the actual production data, the new process dyeing yarn can save approximately It is 50%, but the density of loose cone 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 cone yarn must be controlled at 0.35g / cm 3 ~0.37g / cm 3 In the meantime, it is difficult for the exis...

[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
