Description

Yarn Tension Control Mechanism for Loom

technical field

The utility model relates to a tension control mechanism of a loom yarn, which is arranged on the loom and used to control the tension of the weft yarn or the bottom yarn threaded on the loom.

Background technique

The process of loom weaving fabric or webbing is to weave yarns in all directions through the cross weaving of yarns. A fabric or webbing that meets the requirements must be flat, that is, its weft yarn must be flat when weaving. And the bottom yarn must be kept under a certain tension to weave with the warp yarn, so that it can be woven into a flat cloth or ribbon. When the tension is unstable, due to the unstable tension of each yarn, the woven fabric or webbing will show uneven shapes such as high and low bumps, which will cause poor quality;

In the case of existing looms, after each weft yarn or bottom yarn exits from its spool, each yarn passes through each guide rod (wheel) of the loom or its thread hole and other guiding turns and then enters the weaving mechanism to carry out the process. The weaving of cloth or webbing, that is, each yarn does not have any mechanism to adjust or control the tension of the yarn, so that the yarn in this state cannot ensure that the cloth or webbing can be made after the cloth is woven. Into a flat shape, which is the problem of the current loom;

Especially when weaving wide and narrow belts, because on a certain length of belt, the width of the belt changes with different widths and cycles at intervals. The tension of the "wide" position and the "narrow" position of the body is the same, so when the warp yarns with the same number of yarns and different yarn intervals are woven, the resulting belt body will have an uneven appearance. type of shortcomings.

This shows that above-mentioned existing loom obviously still has inconvenience and defect in structure and use, and demands urgently further improving. In order to solve the problems existing in the existing looms, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products to solve the above problems.
