Description

Creel guides for draw frames

technical field

The invention belongs to the field of mechanical equipment, and in particular relates to a guide frame of a drawing frame.

Background technique

The sliver feeding part of the existing drawing frame is composed of feeding cans, sliver guide rollers, sliver guide rollers, sliver guide platforms and cotton feeding rollers. The sliver is led out from the feeding can by the sliver guide roller and the sliver press roller, and sent to the sliver guide platform in a certain direction. On the high-speed draw frame, the position of the guide roller is close to the feeding can, and the guide roller pulls the sliver to the platform. After that, the sliver is arranged in parallel and sent to the drafting mechanism by the feed roller.

The traditional core-spun yarn generally uses synthetic fiber filaments with good strength and elasticity as the core yarn, and is twisted and spun with short fibers such as cotton, wool, and viscose fibers.

The short-fiber core-spun yarn is generally spun with short-fiber strands as the core yarn and wrapped with another short-fiber. The core-spun yarn can be natural fiber or chemical short-fiber, while the out-wrapped yarn usually uses natural short-fiber.

The invention patent with the publication number CN105755624A discloses a spinning method of short fiber core-spun yarn, which includes the following process steps: first, the core fiber is made by cleaning, carding, drawing, and air spinning; Then, the outer fiber is cleaned, carded, drawn, and roved to make a leather yarn; after that, the core yarn and leather yarn prepared above are fed into the core yarn device in the ring spinning equipment to make a core yarn. yarn, and then the finished air-spun staple fiber core-spun yarn is produced through the winding process. The core-spun yarn prepared by the method has the advantages of soft hand feeling, comfortable wearing and the like.

Publication number is CN201459313U utility model discloses a kind of production method and device thereof of short fiber wrapped composite yarn. A transfer rubber roller is installed in front of the roller drafting mechanism, and a wrapping roller with a groove is added in front of the transfer rubber roller to feed two staple fiber rovings spun from different raw materials, and enter the draft at a fixed distance. Stretching zone, after being drafted in the drafting zone, a short-fiber roving is directly transported to the wrapping roller and enters the groove of the wrapping roller, and two short-fiber rovings are twisted in the groove to form a core-spun yarn.

During the processing of the above-mentioned staple fiber core-spun yarn, the core yarn and the cover yarn are fed through the core-spun yarn feeding part on the spinning frame. Swing, it is easy to cause the core yarn to be exposed, thus affecting the quality of the core yarn.

Contents of the invention
