Description
Technical field
The utility model relates to water-jet loom technical fields, and more specifically, the utility model relates to a kind of water-jet looms
Improvement Weft insertion device.
Background technique
Water-jet loom belongs to jet loom, is to use water as wefting insertion medium, generates friction to weft yarn by injection water
Tractive force makes the weft yarn on fixed bobbin introduce shed open.Water-jet loom needs to guarantee the distance of picking, it is necessary to assure nozzle goes out
Water reduces water yield, will lead to the diffusion of water column, therefore, will consume a large amount of water source when weaving.
The patent of invention of 103147213 A of patent application publication CN discloses a kind of water-jet loom picking structure, including
Nozzle, the nozzle include nozzle core and the thread tube composition for wrapping up the nozzle core, surround the nozzle in the thread tube
Core is evenly equipped at least three water spouts, and the water channel for connecting the water spout, the water spout are provided in the thread tube
It is inside provided with heating device, is provided with condensing unit in the nozzle core, which sprays water for original nozzle of water-jet loom
Reduce into the small water column of multiply, the air in the space for small water column being surrounded using temperature difference principle is shunk, and the anti-diffusion of small water column is made
Ability improves, and while reducing water consumption, ensure that the distance of weft yarn picking.
But it is in actual use, still there are some disadvantages, although as it is made between weft yarn and droplet using the temperature difference
Air shunk under the heat transmitting of weft yarn, and then water column and weft yarn is made to be not susceptible to spread under convergent force, to make
Weft yarn is effectively exported, but since its heating device and condensing unit are all set in inside device, and device at work its
It is internal to be in water-filled state at the moment again, therefore heating device and condensing unit are higher to waterproof requirement during installation, together
When it is also not easy to overhaul, therefore cause its manufacture difficulty larger.
Utility model content
In order to overcome the drawbacks described above of the prior art, the improvement that the embodiments of the present invention provide a kind of water-jet loom is thrown
Weft handling device is flowed, when it flow to second by the way that the water after pressurization to be imported into inside yarn-guiding duct then along yarn-guiding duct
When tilting at water channel and the first inclination water channel, water is entered in nozzle passage by the second inclination water channel and the first inclination water channel, this
When nozzle passage in water drive weft yarn to synchronize and travel forward, while when water flowing is to guide collar at, due to guiding ring cross-section
It is set as triangle, therefore water flow is directed to circle and is oriented to, since guide collar is set on the inside of yarn-guiding duct, guide collar radius
Less than yarn-guiding duct radius, therefore when water flow is flow on the inside of guide collar, water flow is pressurized, then along the end of guide collar
It spraying, the water flow after final pressurization lifts weft yarn, thus guarantee the conveying distance of weft yarn, compared with prior art, this
Utility model realizes the extension of conveying distance by way of changing internal structure, in actual use, do not need using electric power into
Row auxiliary, therefore waterproof requirement and failure rate are also effectively lower than the prior art, manufacture difficulty is relatively low, design rationally, have compared with
