Abstract
This invention discloses a double-pump double-sprayer water loom including an open unit, a weft-leading unit, a beating unit, a warp-feeding unit and a coiling off unit, in which the weft-leading unit includes a water tank connected with the two pumps by a pipeline, the two pumps are connected with two inlet holes by the pipeline and a monomer 2-way cylinder six-channel reversal valve, two outlets of the valve are connected with nozzles, the valve is opened with two backwater holes connected with the water tank by a pipeline, every inlet hole of the valve is corresponding to one outlet hole and a backwater hole and connected with one and the two outlet holes are opened alternately, which can produce fabrics made of two kinds of wefts.
Description
Technical field
The present invention relates to a kind of water jet looms, particularly water-jet loom with dual pumps and dual jets.
Background technology
At present, known water jet looms process structure mainly contains parts such as shedding mechanism, weft insertion device, warp-feeding mechanism, spooler and other auxiliary bodies, and other auxiliary bodies comprise measuring motion, storage Weft handling device, selvage device and Warp stop motions.Weft insertion device generally adopts single pump list spray mode, and it relatively is fit to weave the smallware of being made up of a kind of weft yarn, can not weave the fabric of two kinds of different weft yarns compositions, more can not weave the broad fabrics that the weft yarn that differed greatly by two kinds of fiber numbers is formed.Though occurred a kind of water-jet loom with dual pumps and dual jets that can weave the fabric of two kinds of different weft yarns compositions in the market, its wefting insertion ratio of precision is lower, the loom rotating speed is slow.
Summary of the invention
Task of the present invention is to solve the above-mentioned technological deficiency that water-jet loom with dual pumps and dual jets exists in the prior art, a kind of water-jet loom with dual pumps and dual jets is provided, not only can make the fabric that two kinds of different weft yarns are formed, and have advantages such as wefting insertion precision height, loom rotating speed be fast.
Its technical solution is:
A kind of water-jet loom with dual pumps and dual jets, comprise shedding mechanism, weft insertion device, warp-feeding mechanism and spooler, weft insertion device comprises supply tank, supply tank is connected with two water pumps by pipeline, two water pumps are communicated with two inlet openings of single two-way plunger six passage reversal valves by pipeline respectively, two apopores of reversal valve are connected with nozzle respectively, reversal valve also offers two backwater holes, two backwater holes are communicated with supply tank by pipeline, the respectively corresponding apopore in each inlet opening and a backwater hole of reversal valve, and select one and communicate, two apopores are alternately open-minded.
Be provided with the decompression water recovery apparatus between above-mentioned backwater hole and the supply tank, the decompression water recovery apparatus is communicated with supply tank by pipeline.
Above-mentioned warp-feeding mechanism comprises the tension connecting rod that is connected with back rest roller, and the tension connecting rod is connected with the tension arm by rotating shaft, is equipped with the tension spring on the tension arm.
Water-jet loom with dual pumps and dual jets of the present invention, owing to adopted two water pumps to be connected with a single two-way plunger six passage reversal valves at weft insertion device, two apopores on the reversal valve replace water outlet, when inlet opening on the reversal valve when corresponding apopore is connected, another inlet opening is connected with backwater hole, a reversal valve can be controlled water inlet, water outlet and the backwater of two water pumps simultaneously, has improved wefting insertion precision and loom rotating speed; Simultaneously between backwater hole and supply tank, be provided with the decompression water recovery apparatus, solved pressure of return water, avoided that the impact because of backwater produces bubble in the weaving process, cause the sky of wefting insertion to stop the impact that supply tank causes; Warp-feeding mechanism is simple in structure, and can regulate warp run-in and warp tension voluntarily according to the filling density of fabric, has improved weave quality.
Description of drawings
Fig. 1 is the structured flowchart of weft insertion device water supply part among the present invention;
Fig. 2 is the structure diagram of warp-feeding mechanism among the present invention.
The present invention will be described below in conjunction with accompanying drawing:
The specific embodiment
Water-jet loom with dual pumps and dual jets of the present invention, parts such as its shedding mechanism, weft insertion device, beating-up mechanism, warp-feeding mechanism, spooler and other auxiliary bodies except that following technology contents, all can adopt prior art.Below in conjunction with related art feature the most, and stress the technical characterictic that the present invention contributes to prior art:
In conjunction with Fig. 1, weft insertion device among the present invention, comprise supply tank 1, supply tank 1 is connected with two water pumps 2 and 3 by pipeline, two water pumps 2 and 3 are communicated with two inlet openings 41 and 42 of single two-way plunger six passage reversal valves 4 by pipeline respectively, two apopores 43 of reversal valve 4 and 44 are connected with the nozzle (not shown) respectively, reversal valve also offers two backwater holes 45 and 46, two backwater holes 45 and 46 are communicated with decompression water recovery apparatus 5 by pipeline, and the water recovery apparatus 5 that reduces pressure is communicated with supply tank by pipeline.Inlet opening 41 can be selected one with apopore 43 and backwater hole 45 and is communicated with, inlet opening 42 can be selected one with apopore 44 and backwater hole 46 and is communicated with, apopore 43 and 44 alternately water outlets, when inlet opening 41 when corresponding apopore 43 is connected, inlet opening 42 is connected with backwater hole 46, when inlet opening 42 when corresponding apopore 44 is connected, inlet opening 41 is connected with backwater hole 45, a reversal valve can be controlled water inlet, water outlet and the backwater of two water pumps simultaneously, has improved wefting insertion precision and loom rotating speed; Simultaneously between backwater hole and supply tank, be provided with the decompression water recovery apparatus, solved pressure of return water, avoided that the impact because of backwater produces bubble in the weaving process, cause the sky of wefting insertion to stop the impact that supply tank causes.
In conjunction with Fig. 2, the warp-feeding mechanism among the present invention, it comprises the tension connecting rod 6 that is connected with back rest roller (not shown), tension connecting rod 6 is connected with tension arm 8 by rotating shaft 7, is equipped with tension spring 9 on the tension arm 8.This warp-feeding mechanism compared with prior art has simple in structurely, and can regulate warp run-in and warp tension voluntarily according to the filling density of fabric, has improved weave quality.
