By adopting technique scheme, due to static and pressure factor, yarn can be attached to roller skin, and anti-down roll bending just plays the effect that yarn is scraped off from roller skin; If anti-down roll bending fails in time yarn is scraped and causes yarn to continue to be wound on roller skin from roller skin, corresponding infrared receiving/transmission inductor will produce warning because signal cuts off, and system stops braiding automatically.Whole apparatus structure is simple, highly sensitive, operating efficiency is high, product quality is high, and production cost is low.
The utility model is further set to: in described glove groove, be provided with two pairs of anti-down roll bendings, every anti-down roll bending and the first magnet steel are all inlayed and are integrally formed by injection moulding.By this setting, anti-down roll bending and the first magnet steel are fixing reliable, long service life.
The utility model is also further set to: on described glove groove internal face, a pair of infrared inductor is set altogether, described the second magnet steel and inductor seat are inlayed and are integrally formed by injection moulding.By this setting, the second magnet steel is connected reliably with inductor seat, long service life.
The utility model is also further set to: described infrared receiving/transmission inductor is connected and fixed by screw and inductor seat.By this setting, infrared receiving/transmission inductor and inductor seat are easy to connect, and mounting or dismounting easily.
The utility model is also further set to: described infrared receiving/transmission inductor arranges near roller skin, and infrared receiving/transmission inductor working face and roller skin outer surface 0.5mm apart.By this setting, described infrared receiving/transmission sensor location arranges rationally, reliable operation.
The utility model has the advantages that: compared with prior art, the utility model structure arranges rationally, and due to static and pressure factor, yarn can be attached to roller skin, and anti-down roll bending just plays the effect that yarn is scraped off from roller skin; If anti-down roll bending fails in time yarn is scraped and causes yarn to continue to be wound on roller skin from roller skin, corresponding infrared receiving/transmission inductor will produce warning because signal cuts off, and system stops braiding automatically.Whole apparatus structure is simple, highly sensitive, operating efficiency is high, product quality is high, and production cost is low.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
