Tension balance type flying shuttle and balance assembly

Abstract

The invention discloses a tension balance type flying shuttle and a balance assembly. The tension balance type flying shuttle includes a frame body, wherein the frame body is provided with a porcelain eye and a yarn shaft used for mounting a yarn roll, the tension balance type flying shuttle further includes the balance assembly, the balance assembly includes a balance plate, the balance plate is provided with a cambered surface, silk yarn is led out from yarn outlet points of the yarn roll, the silk yarn passes through the cambered surface and then reaches the porcelain eye, and due to the cambered surface, the lengths of the silk yarn from any yarn outlet point of the yarn roll to the porcelain eye are equal. According to the tension balance type flying shuttle and the balance assembly provided by the invention, the tension of the silk yarn can be basically kept unchanged after the yarn outlet point is continuously changed, so that the silk yarn is not easy to break.

Description

technical field [0001] The invention relates to the technical field of circular looms, in particular to a tension-balanced shuttle and a balance assembly. Background technique [0002] Please refer to figure 1 , in the old-style shuttle, the yarn reel is placed horizontally relative to the shuttle track, and then the thread exit is completed through the flagpole set next to the yarn reel. When exiting the thread, the exit point changes back and forth between the two ends of the yarn roll (that is, the three points ABC change back and forth), due to the distance from point B to the outlet porcelain eye, compared with the distance from A and C to the outlet porcelain eye. Short, so when the outlet speed is constant, as the outlet point changes on the yarn roll, the tension of the thread is constantly changing. The diagram of the tension change can be referred to figure 2 . And if the pulling force of the silk thread is always changing, it is easy to cause the thread to bre...

AI Technical Summary

Problems solved by technology

Compared with the old-style shuttle, the outlet of the radial shuttle needs to go through two ceramic eyes, so the distance between the first porcelain eye and the outlet point is smaller than the distance between the porcelain eye and the outlet point of the old-style shuttle, so the radiation The tension of the thread of the shuttle is more variable, and it is more likely to cause the thread to break

And due to environmental protection issues and different use conditions of finished bags, recycled materials are often used or calcium carbonate or other additives are added, resulting in a relatively low tension value of the silk thread and easy to tear
