Warp stop control box with segmented display function

Abstract

The invention provides a warp stop control box with a segmented display function, and belongs to the technical field of accessories of warp stop bars of looms. The warp stop control box comprises a detection circuit, a current limiting circuit, a reduction voltage circuit and a reset circuit, wherein the reduction voltage circuit is connected with machinery equipment, the reduction voltage circuitis also connected with the current limiting circuit and the detection circuit separately to provide reduced-voltage power for the current limiting circuit and the detection circuit, the current limiting circuit is connected with a warp stop bar and used for supplying the reduced-voltage power after current limiting to the warp stop bar for use, the detection circuit is connected with the warp stop bar and connected with the machinery equipment through an output circuit, the machinery equipment is controlled to run by judging a state signal given by the warp stop bar, the reset circuit is connected with the reduction voltage circuit and the machinery equipment, and after a reset signal transmitted by the machinery equipment is received, the reduction voltage circuit is controlled to stop working. The problem can be avoided that faults cannot be accurately displayed due to the poor contact of a droop wire in the previous structure; the current limiting circuit provides limited current for the warp stop bar to prevent the warp stop bar from causing a fire after exceeding a limited current, thereby playing a protective role.

Description

technical field [0001] The invention belongs to the technical field of menopause strip accessories of looms, and in particular relates to a segmented display warp stop control box. Background technique [0002] Shuttleless looms are equipped with a warp stop frame. The function of the warp stop frame is to set the menopause strips. The menopause strips are strung with warp yarns, and each warp strip is threaded with a warp yarn. state, at this time, the chip on the menopause bar and the clad iron are in a non-conductive state due to the isolation of the insulating clip. When a certain warp yarn is disconnected, the warp stopper that was originally in the suspended state will drop to the warp stop bar because of losing the tube bundle of the warp yarn, so that the chip in the insulating and separated state is connected to the cladding iron, and passes through the warp stop box on the warp stop frame (also Called "warp stop junction box"), the signal is fed back to the electr...

AI Technical Summary

Problems solved by technology

In the actual production and application process, affected by environmental factors in the workshop, the menopause often has poor contact problems due to fluff and dust on site. If it does happen, the existing display device will not display it in time, so that the operator cannot find the broken warp yarn and connect it in the first place, which will eventually affect the quality of the finished product and the working efficiency of the loom
