Described a kind of air-jet loom piezoelectric type yarn break preventing supervising device of the present invention, power supply 24V is connected with resistance R 1, resistance R 1 with connect IC 7812 and be connected, be connected with capacitor C 1, C2 again, meet LED1, connecting resistance R3 again, connecting resistance R2 is connected in series triode V1, V2 base stage again, the other end is connected to the S end of yarn break controller, the colelctor electrode of the other end serial connection triode V1 of wiring circle K1, coil K1, the grounded emitter of triode V1, connecting resistance R4, meet LED2 again, LED2 is connected to the colelctor electrode of triode V2, the grounded emitter of triode V2; The V end of V termination detection head (1), G connect the G end of detection head (1), S termination detection head S end, and C, D connect the C of loom, the signal end of D, and B ' yarn break controller is identical with A ' yarn break controller circuit connection diagram.

The invention has the beneficial effects as follows that yarn detects weft yarn by piezoelectric probe, form by single detection head for every group, disconnected when weft yarn, perhaps take place to stop for yarn, the signal that cut-offs is sent in the detector action, and loom stops to produce; It adopts the piezoelectricity principle of induction, and is easy to use, is convenient to regulate, simple in structure, has improved the quality of high-count and high-density grey cloth product, and has substituted the import like product.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples
