Abstract
The invention discloses a high-speed air-jet loom with four nozzles, consisting of a shedding mechanism, a weft insertion mechanism, a let-off mechanism and a take-up mechanism. The weft insertion mechanism comprises a relief valve, a high-frequency valve and nozzles. The nozzles comprise four fixed nozzles and a moving nozzle; four nozzles are arranged side by side in front of a weft storage device: the moving nozzle is arranged in front of fixed nozzles. The invention adopts an active cam shedding mechanism, a stable back beam mechanism and an independent rolling mechanism. The loom of the invention can weave various yarns with different colors and specifications so as to improve the ratio of weft insertion and weaving quality.
Description
Technical field
The present invention relates to a kind of water jet looms, particularly high-speed four-jet air-jet loom.
Background technology
Present air-jet loom is because the restriction of beat up angle, the dynamics of beating up is not suitable for weaving various different thicknesses, the yarn of different colours; Simultaneously because air-jet loom adopts the passive type cam shedding mechanism mostly, when weaving the long yarn of filoplume, opening is not very clear, and the wefting insertion rate is not high.
Summary of the invention
Task of the present invention is to provide a kind of high-speed four-jet air-jet loom, and it has the great efforts of beating up, can weave highly denser fabric, and weaving efficiency compares advantages of higher.
Its technical solution is:
High-speed four-jet air-jet loom, comprise shedding mechanism, weft insertion device, warp-feeding mechanism and spooler, weft insertion device comprises pressure-reducing valve, high frequency valve and nozzle, described nozzle comprises four fixed nozzles and a moving nozzle, four fixed nozzles are arranged side by side the place ahead at weft accumulator, and moving nozzle is arranged on the place ahead of fixed nozzle.
Above-mentioned shedding mechanism adopts the conjugate cam shedding mechanism, two cam bits of conjugate cam are conjuncted structure, the camshaft of conjugate cam and driven synchronous pulley are through the bevel gear driving coupling, cam bit is furnished with cam follower up and down, cam follower connects swing arm up and down, and swing arm connects connecting rod, and connecting rod connects the shedding arm, the shedding arm links montant, and montant connects heald frame.
Above-mentioned warp-feeding mechanism is connected with the back rest of loom, and the back rest comprises the fixedly back rest, and fixedly the back rest is fixed on the wallboard, and fixedly the back rest is connected with the movable back rest, and the movable back rest is connected with steady connecting rod.
Above-mentioned coiled body comprises servomotor, and servomotor links by reduction box and friction roller, and friction roller drives crimping roller by turbine box and rotates.
High-speed four-jet air-jet loom of the present invention, owing to adopted four fixed nozzles and a moving nozzle, realized that different colours different size yarn arrives and knitted end in the identical time, remedied the defective that single spray, two spray can not be made, improve the fabric class, enlarged the scope of weaving, adopted pressure-reducing valve and high frequency valve, reduce air consumption, saved the energy; Adopt the conjugate cam shedding mechanism simultaneously, be improved to positive shedding, thereby the shedding mechanism running speed is fast, the clear weave effect that reaches COTTON FABRIC of opening, has improved the wefting insertion rate by original negative shedding; The back rest of this air-jet loom is compared with the back rest of existing air-jet loom has increased the fixedly back rest, has stablized warp tension, has reduced the cracked ends rate, and has stablized warp run-in by steady connecting rod, has improved production efficiency; Coiled body adopts independent servo motor, has improved accuracy, curl steadily, has eliminated machine crimp and knit ruffian in weaving, and has improved weave quality and efficient.
