Abstract
A pneumatic weft yarn folding-in nozzle comprises air injection holes (2) arranged on the nozzle. A yarn groove (1) is arranged in the nozzle, four air injection holes (2) with the inclination angles of 9-10 degrees are arranged on two sides of the groove, a first air path (3) is communicated with two air injection holes, a second air path (4) is communicated with other two air injection holes, a third air path (5) is communicated with the end of the yarn groove, and a fourth air path (6) is also communicated with the end of the yarn groove. The pneumatic weft yarn folding-in nozzle is divided into a left part and a right part, weft yarn penetrates through the yarn groove in the middle of the nozzle in the flying process, the four air injection holes on two sides of the groove eject high-speed air flow under the control of three electromagnetic valve to enable redundant weft yarn generated when the weft yarn is cut off to be folded into open warp yarn, so that a plain edge is woven, and product quality and the grade are greatly improved.
Description
Technical field
The present invention relates to a kind of nozzle, relate in particular to a kind of pneumatic weft yarn and fold into nozzle.
Background technology
Air-jet loom is to adopt jet-stream wind weft traction to pass through shed open
shuttleless loom.Operation principle is to utilize air as wefting insertion medium, with the compressed air stream ejecting, weft yarn is produced to frictional traction and draws, and weft yarn band is crossed to shed open, reaches the object of wefting insertion by the jet of jet generation.This filling insertion way can make loom realize high speed high yield.In several shuttleless looms, air-jet loom is the highest a kind of of the speed of a motor vehicle, because filling insertion way is reasonable, enter latitude rate higher, running operation handy and safe, has varietal adaptation wider, machine material consumption is few, the advantages such as efficiency is high, and the speed of a motor vehicle is high, noise is low, have become one of Novel cloth machine of tool development prospect.Existing air-jet loom is in weaving process, the both sides weft yarn of fabric unnecessary weft yarn beyond the warp thread after scissors is cut off cannot fold in the warp thread of opening and go, unnecessary weft yarn becomes burr, has reduced the class of textiles, also affects the quality of product simultaneously.
Summary of the invention
The object of this invention is to provide a kind of pneumatic weft yarn and fold into nozzle, can solve the difficult technical problem of eliminating of textiles burr.
The object of the invention is to realize as follows: a kind of pneumatic weft yarn folds into nozzle, comprises fumarole disposed thereon, it is characterized in that: on nozzle, be equipped with yarn groove, the both sides of groove are provided with the fumarole that 4 angles of inclination are 9-10 degree; First air flue is connected with 2 fumaroles, and second air flue is connected with another 2 fumaroles, and the 3rd air flue is connected with mistake yarn groove end, and the 4th air flue is also connected with mistake yarn groove end.
A kind of pneumatic weft yarn of the present invention folds into nozzle, and the groove width of crossing yarn groove is 1mm, and length is 13.5mm, crosses the yarn trough portion structure that stretches out and is 90 degree, and the diameter of 4 fumaroles is 1.2mm, and spacing is respectively 3mm.
In the present invention, pneumatic weft yarn folds into nozzle and divides two of left and right, in weft yarn flight course, from the middle yarn groove of crossing of nozzle, pass, the unnecessary weft yarn that 4 fumaroles of groove both sides spray high velocity air under three solenoid control to be produced when weft yarn is cut off folds in the warp thread of opening, make it to be made into plain edge, greatly improved product quality and class.
Accompanying drawing explanation
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation below, wherein:
Accompanying drawing is depicted as structural representation of the present invention
In figure: 1, cross yarn groove 2, fumarole 3, first air flue 4, second air flue 5, the 3rd air flue 6, the 4th air flue
With reference to accompanying drawing, a kind of pneumatic weft yarn folds into nozzle, comprises fumarole disposed thereon 2, is equipped with yarn groove 1 on nozzle, and the both sides of groove are provided with the fumarole 2 that 4 angles of inclination are 9-10 degree; First air flue 3 is connected with 2 fumaroles, and second air flue 4 is connected with another 2 fumaroles, and the 3rd air flue 5 is connected with mistake yarn groove end, and the 4th air flue 6 is also connected with mistake yarn groove end.As another embodiment of the invention, the groove width of crossing yarn groove is 1mm, and length is 13.5mm, crosses the yarn trough portion structure that stretches out and is 90 degree, and the diameter of 4 fumaroles is 1.2mm, and spacing is respectively 3mm.
Pneumatic weft yarn folds into nozzle and divides two of left and right, in weft yarn flight course, from then on crossing yarn groove passes, 4 fumaroles are communicated with respectively four tracheaes, wherein two holes are series of holes, with a tracheae air feed, use respectively three solenoid control, the high velocity air boundling that makes it ejection can cross at the 10mm place in aperture.When after a wefting insertion completes, scissors is cut off weft yarn, pneumatic weft yarn folds in the warp thread that nozzle ejection air-flow folds into unnecessary weft yarn opening fast, makes it to be made into plain edge.Pneumatic weft yarn folds into nozzle and installs on the filling cutter mounting bracket of left and right, must be the friendship hole point of 4 air outlets aligning Warp opening place during installation, be convenient in warp thread that unnecessary weft yarn can enter opening smoothly.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. pneumatic weft yarn folds into a nozzle, comprises fumarole disposed thereon, it is characterized in that: on nozzle, be equipped with yarn groove, the both sides of groove are provided with the fumarole that 4 angles of inclination are 9-10 degree; First passage is connected with 2 fumaroles, and second air flue is connected with another 2 fumaroles, and the 3rd air flue is connected with mistake yarn groove end, and the 4th air flue is also connected with mistake yarn groove end.
2. a kind of pneumatic weft yarn according to claim 1 folds into nozzle, it is characterized in that the described groove width of crossing yarn groove is 1mm, and length is 13.5mm, crosses the yarn trough portion structure that stretches out and is 90 degree, and the diameter of 4 fumaroles is 1.2mm, and spacing is respectively 3mm.
