Existing Computerized flat knitting machine is all to utilize roller to carry out granny rag; in process of production, often there will be cloth to be wrapped in abnormally on roller, utilize mechanical type anti-rewinding device; sensitivity is not high; if do not find in time, cloth will twine more and more, produces waste product, takes material; because of twister, crossing as many as roller skin damages; cause waste of material, production cost is high, causes every machine moon loss 400-500 unit.This had both been unfavorable for increasing work efficiency, and was also unfavorable for reducing production costs.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide the roller back roll prevention infrared sensing device that one is simple in structure, highly sensitive, operating efficiency is high, production cost is low.
For achieving the above object, the invention provides following technical scheme: a kind of roller back roll prevention infrared sensing device, comprise frame, described central rack is provided with glove groove, in arranging in described glove groove, be at least provided with a pair of anti-down roll bending, on described every anti-down roll bending, be installed with the first magnet steel, every anti-down roll bending is adsorbed on by the first magnet steel on the internal face of glove groove, on described every anti-down roll bending upper end, be provided with roller skin, two ends, described glove groove internal face left and right are at least provided with a pair of infrared inductor, described infrared inductor comprises infrared receiving/transmission inductor and inductor seat, described infrared receiving/transmission inductor is fixedly connected with inductor seat, on inductor seat, be fixedly installed the second magnet steel, described inductor seat is adsorbed on the internal face of glove groove by the second magnet steel.
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 present invention 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 present invention 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 present invention 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 present invention 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.
Advantage of the present invention is: compared with prior art, structure of the present invention 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 invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structural representation of the anti-down roll bending of the embodiment of the present invention;
Fig. 3 is the structural representation of embodiment of the present invention infrared inductor.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of roller back roll prevention infrared sensing device disclosed by the invention, comprise frame 1, described frame 1 middle part is provided with glove groove 11, in interior setting of described glove groove 11, be at least provided with a pair of anti-down roll bending 2, on described every anti-down roll bending 2, be installed with the first magnet steel 3, every anti-down roll bending 2 is adsorbed on the internal face of glove groove 11 by the first magnet steel 3, on described every anti-down roll bending 2 upper ends, be provided with roller skin 4, as preferably, roller skin 4 lower surfaces arrange near the anti-down roll bending 2 of below, distance between the anti-down roll bending 2 of roller skin 4 arranges according to actual needs, this technology is this area routine techniques, the present embodiment is symmetrical arranged two roller skins 4 altogether, described glove groove 11 two ends, internal face left and right are at least provided with a pair of infrared inductor 5, described infrared inductor 5 comprises infrared receiving/transmission inductor 51 and inductor seat 52, described infrared receiving/transmission inductor 51 is fixedly connected with inductor seat 52, on inductor seat 52, be fixedly installed the second magnet steel 53, described inductor seat 52 is adsorbed on the internal face of glove groove 11 by the second magnet steel 53.The first magnet steel 3 and the second magnet steel 53 and glove groove 11 internal faces adsorb that fixing technology is well known to those skilled in the art, and the present embodiment is just no longer narrated.
For making structure of the present invention more reasonable, as preferably, in glove groove 11, be provided with two pairs of anti-down roll bendings 2 described in the present embodiment, every anti-down roll bending 2 and the first magnet steel 3 are all inlayed and are integrally formed by injection moulding.On described glove groove 11 internal faces, a pair of infrared inductor 5 is set altogether, described the second magnet steel 53 is inlayed and is integrally formed by injection moulding with inductor seat 52.Described infrared receiving/transmission inductor 51 is connected and fixed by screw and inductor seat 52.
