Abstract

The utility model discloses a pneumatic weft invagination nozzle comprising gas orifices (2) arranged on the pneumatic weft invagination nozzle, wherein a yarn groove (1) is arranged on the nozzle; four gas orifices (2) of which the inclination angles are 9-10 degrees are arranged at two sides of the groove; a first air flue (3) is communicated with two gas orifices; a second air flue (4) is communicated with another two gas orifices; a third air flue (5) is communicated with the end part of the yarn groove; a fourth air flue (6) is also communicated with the end part of the yarn groove. By adopting the structure disclosed by the utility model, the pneumatic weft invagination nozzle is divided into left and right two pieces; a weft passes through the yarn groove in the middle of the nozzle during the flight; and the four gas orifices at two sides of the groove jet high-speed airflow to fold excessive weft generated when the weft is cut off into the opened warp under the control of three electromagnetic valves, so that the weft is woven into an optical margin. Thus, the quality and grade of the product are greatly improved.

Description

A kind of pneumatic weft yarn folds into nozzle

Technical field

The utility model relates to a kind of nozzle, relates in particular to a kind of pneumatic weft yarn and folds into nozzle.

Background technology

Air-jet loom is to adopt the jet-stream wind weft traction to pass through shed open Shuttleless loomOperation principle is to utilize air as the wefting insertion medium, with the compressed air stream that ejects weft yarn is produced frictional traction and draws, and the weft yarn band is crossed shed open, reaches the purpose of wefting insertion by the jet of jet generation.This filling insertion way can make loom realize the 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, it is higher to enter the latitude rate, the running operation handy and safe, and it is wider to have a varietal adaptation, machine material consumption is few, the advantages such as efficient 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 can't 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.

The utility model content

The purpose of this utility model provides a kind of pneumatic weft yarn and folds into nozzle, can solve the difficult technical problem of eliminating of textiles burr.

The purpose of this utility model realizes as follows: a kind of pneumatic weft yarn folds into nozzle, comprises fumarole disposed thereon, it is characterized in that: be equipped with the yarn groove on the nozzle, the fumarole that it is the 9-10 degree that the both sides of groove are provided with 4 angles of inclination; First air flue is connected with 2 fumaroles, and 2 fumaroles of second air flue and other are connected, and the 3rd air flue is connected with mistake yarn groove end, and the 4th air flue also is connected with mistake yarn groove end.

A kind of pneumatic weft yarn described in the utility model folds into nozzle, and the groove width of crossing the yarn groove is 1mm, and length is 13.5mm, crosses the yarn trough section structure that stretches out and is 90 degree, and the diameter of 4 fumaroles is 1.2mm, and spacing respectively is 3mm.

In the utility model, about pneumatic weft yarn folds into nozzle and divides two, pass from the middle yarn groove of crossing of nozzle in the weft yarn flight course, the unnecessary weft yarn that 4 fumaroles of groove both sides spray high velocity air under three solenoid control produce 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.

Description of drawings

Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:

Accompanying drawing is depicted as structural representation of the present utility model

Among the 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 the nozzle, the fumarole 2 that it is the 9-10 degree that the both sides of groove are provided with 4 angles of inclination; First air flue 3 is connected with 2 fumaroles, and 2 fumaroles of second air flue 4 and other are connected, and the 3rd air flue 5 is connected with mistake yarn groove end, and the 4th air flue 6 also is connected with mistake yarn groove end.As another kind of embodiment of the present utility model, the groove width of crossing the yarn groove is 1mm, and length is 13.5mm, crosses the yarn trough section structure that stretches out and is 90 degree, and the diameter of 4 fumaroles is 1.2mm, and spacing respectively is 3mm.

About pneumatic weft yarn folds into nozzle and divides two, from then on crossing the yarn groove in the weft yarn flight course 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 to spray can cross at the 10mm place in aperture.When scissors was cut off weft yarn after a wefting insertion is finished, pneumatic weft yarn folded 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 the left and right sides, must be the friendship hole point of 4 air outlets aligning Warp opening place during installation, be convenient in the warp thread that unnecessary weft yarn can enter opening smoothly.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims
