Problems solved by technology

In addition, when the weft stops, there are several free weft yarns in the weft mouth, and it is easy to pull out the normal weft yarns during operation, resulting in weft-defective fabrics.
After the warp is changed to double-weft weaving and heavy flat weave, the weft yarn is not twisted by the dyeing yarn winding. Although the efficiency of the loom is improved and the dense road defect fabric is improved, the following problems still exist: ① Doubling Add a processing procedure, increase production time and production cost; ②Single yarn phenomenon appears on the doubling bobbin; ③Inconsistent tension of the two yarns on the doubling bobbin causes kink and defective fabric; ④Weft breakage and other defective fabrics appear on the machine

Embodiment Construction

[0013] The weft breaking self-stop device is a device that detects the yarn breaking signal and transmits the yarn breaking signal to loom to stop the loom; this device can also be used to weave weaving varieties that cannot have knots by detecting a single weft yarn. machine, stop the loom, and start the machine after disposing of the weft yarn in the knotted part.

[0014] The weft-continuing self-stop device on each loom can be equipped with multiple weft-broken detection switches. When there are unused weft-broken detection switches, they can be placed in idle gear without affecting the detection of other weft-broken switches. Weft breakage detection switch can adopt contact switch, photoelectric sensor switch or other types of yarn sensor switch, when any weft breakage detection switch detects the signal of weft yarn breakage, it will send the detection master number to the main controller of the loom , the main controller processes the signal and sends a stop command to...

Abstract

A weft-break stop motino for textile machine features that the hollow column with control signal lines in it is installed between pirn and weft accumulator of loom and has N weft detecting switches with induction ring on the end of its detecting rod. The induction ring is concentric with the weft hole on the weft guider.

Description

technical field [0001] The invention relates to a device of a textile machine, in particular to a weft breaking self-stopping device used in the weaving of heavy flat weaves. Background technique [0002] In the prior art, one kind of weaving variety with warp flat weave is always woven on a dobby loom. This kind of variety has the following disadvantages when weaving: repeat throwing several weft yarns in the same opening state, and when the fault stops There are two states: one is that the heald frame is open and the warp tension is high; the other is that the heald frame is closed and the warp tension is small. It is difficult to avoid the dense path produced by these two states by adjusting the technological parameters of the loom. In addition, when the weft stops, there are several free weft yarns in the weft mouth, and it is easy to pull out the normal weft yarns during operation, resulting in weft-defective fabrics. After the warp is changed to double-weft weaving a...
