Inversion-type cylinder weft yarn unwinding device

Abstract

The invention discloses an inversion-type cylinder weft yarn unwinding device. The device is characterized in that a cone-shaped rod is provided with a hook, the hook is hung on a weft yarn rack, the cone-shaped rod is inserted into a paper-made cone-shaped pipe in the center of the inverted cylinder weft yarn, a bolt is arranged in a bolt hole in the lower end of the cone-shaped rod, the cylinder weft yarn is fixed on the cone-shaped rod, the yarns on the cylinder weft yarn are inserted into a broken line hole in a yarn returning porcelain base and a yarn guiding hole in a yarn guiding porcelain block and enter a weft accumulator. By the inversion-type cylinder weft yarn unwinding device provided by the invention, the problems that the weft yarns wind falling staple fiber when weft yarns are unwound and the weft yarns are carried in yarn fault is solved in a gripper loom, the quality of the cloth cover is effectively improved, and the economic benefits of enterprises are increased.

Description

technical field [0001] The invention relates to a spinning unwinding device, in particular to an inverted bobbin weft yarn unwinding device for a rapier loom. Background technique [0002] In the existing weft unwinding technology of rapier looms, the weft unwinding method of rapier looms is: upward vertical unwinding, and the installation diagram is shown in figure 2 ;The technological process is: place the package weft yarn on the package yarn support plate of the weft storage frame, with the rotation of the weft storage device, the weft yarn enters the weft storage device through the yarn introduction hole on the weft yarn creel, and the yarn is unwound When the line speed reaches 250-270M / mi, the short fiber weft on the yarn will be rubbed off when it passes through the yarn drawing porcelain eye, and the short fiber weft will fall and accumulate on the upper surface of the package yarn. Under the condition, it is very easy to entangle with the high-speed unwinding yarn...

AI Technical Summary

Problems solved by technology

[0002] In the existing rapier loom weft yarn unwinding technology, the weft yarn unwinding method of rapier loom is: upward vertical unwinding type, the installation diagram is shown in figure 2 ;The technological process is as follows: place the bobbin weft yarn on the bobbin supporting plate of the weft storage rack, and with the rotation of the weft feeder, the weft yarn enters the weft feeder through the yarn drawing hole on the weft yarn creel, and the yarn is unwound When the line speed reaches 250-270M / mi, the short fiber weft on the yarn will be rubbed off when it passes through the yarn drawing porcelain eye, and the short fiber weft will fall and accumulate on the upper surface of the package yarn. It is very easy to entangle with the high-speed unwinding yarn, and the yarn defects will be brought into the weft yarn, forming weft defects on the cloth surface, which will seriously affect the quality of the finished cloth and the economic benefits of the enterprise.
