Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings:

[0016] attached figure 2 It is the improved principle circuit of the photoelectric weft probe of the water jet loom. In the sending part 1, R1 is a step-down resistor, and D1 is an infrared transmitting tube; in the receiving circuit, R2 is a balance resistor, and D2 is an infrared receiving tube; In the shaping part 3, A1 is only a schematic diagram of a monostable trigger, and the omitted part should be restored during installation. There are not many original monostable triggers added, which can be installed in the cavity of the weft probe, or a small box can be added to the tail of the weft probe.

Abstract

The invention discloses a photoelectric probe weft head improved circuit for a water jet loom, which just needs to add a shaping circuit in the original circuit, and then can greatly improve the weft stability of the water jet loom. The shaping circuit is composed of a monostable flip flop. The input and output terminal of the monostable flip flop cuts down the part signal output line of the original circuit, and then accesses respectively. The positive and negative ends of power supply on the monostable flip flop can connect with the positive and negative ends of the power supply. The photoelectric probe weft head improved circuit for the water jet loom is not many in alterations, but can effectively stop weft device a miscarriage of justice resulting from uneven weft and uneven water quality.

Description

[0001] Technical field: [0002] The invention relates to a weft detecting device of a water jet loom, which is particularly suitable for the upgrading and reconstruction of the photoelectric weft detecting head circuit of the water jet loom. [0003] Background technique: [0004] At present, the photoelectric weft detecting head of the popular water jet loom generally has such a problem, that is, when the thickness of the weft thread is uneven or there are impurities in the water, the loom will stop by mistake. [0005] Invention content: [0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an improved circuit, which has a simple structure and only needs to make minor changes to the original weft probe. [0007] The technical scheme of the invention is as follows: the improved circuit of the photoelectric weft probe of the water jet loom only needs to add a first-level shaping circuit to the original circuit; the shaping ...
