The system comprises a main nozzle and an air supply system connected with the main nozzle, wherein the weft yarn is wound on a weft yarn bobbin and lead into the main nozzle; the main nozzle is arranged on a main nozzle seat; the main nozzle seat is arranged on a working platform; the working platform is also provided with an angle square; and the scale end of the angle square is located on the extension line of a main nozzle guide pipe. The system for measuring the stability of the weft yarn carried by a main jet flow disclosed by the invention adopts a simple and feasible measuring means and can effectively measure the stability condition of the weft yarn.
Description
Technical field
The invention belongs to the air-jet loom field, the concrete weft insertion system that relates to air-jet loom more specifically, the present invention relates to a kind of system of measuring the stability of the weft yarn that the main jet air-flow carries.
Background technology
The used in jet loom air-flow is realized wefting insertion, one minute wefting insertion of air-jet loom 800-1000 time, and each wefting insertion correspondence weft yarn flies through shed open once, and the weft yarn flying speed reaches 100 meter per seconds.Have only the weft yarn flying speed high, just can reach loom 800-1000 rev/min high speed.High-speed air-jet looms just must the measured main burner of matter, reaches the high speed more than 100 meter per seconds through the weft yarn behind the main burner, at a high speed must high stable.
Actual motion speed at the newly-increased air-jet loom of factory reaches 750-900 Zhuan ∕ branch.In 88 years, the rotating speed of air-jet loom was 500-600 rev/min, and the weft yarn flying speed is the 45-60 meter per second; Rotating speed reaches 750-1000 rev/min now, and the weft yarn flying speed reaches the 100-110 meter per second, goes into the latitude rate and reaches 2000 meters/minute.And the critical component that quickens weft yarn is exactly a main burner.The quality index of weighing main burner is the flying speed and the stability of weft yarn after main burner quickens, and weft yarn must fly in the reed groove, and auxilliary gaseous blast will steadily connect and draw the main jet air-flow.
The quality of the jet-stream wind of main burner is the key that reaches the weft yarn high-speed flight; Under the effect of main injection air-flow; The weft yarn flying speed just reached flight the most at a high speed, the auxilliary gaseous blast of a plurality of pilot jets of arranging along reed width is just kept this speed, does not allow speed in the reed groove, to fall.Weft yarn leaps shed open under the guiding of weft tracting flow, filling speed is fast more, and the ability that weft yarn leaps shed open is strong more.Major-minor nozzle supply gas pressure is different, and gas supply flow is also different, in the voltage supply scope, must guarantee the stable of weft yarn flight.
Yet, in the measurement of existing main nozzle of jet loom quality, there is not air-flow to carry weft yarn stability as measurement index, there is not similar measurement mechanism yet.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of main jet air-flow that can effectively measure the weft yarn steadiness to carry weft yarn stability measurement system.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of main jet air-flow carries weft yarn stability measurement system; Comprise main burner and connect the air supply system of said main burner; Weft yarn is on the weft yarn bobbin and introduce in the said main burner, and said main burner is arranged on the main burner seat, and said main burner seat is arranged on the workbench; Also be provided with an angle square on the said workbench, the scale end of said angle square is positioned on the extension line of guide wire center line of said main burner.
Further main jet air-flow of the present invention carries weft yarn stability measurement system and also comprises a clamper; Said clamper mainly is made up of a minor axis and two round ceramics being set in successively on the said minor axis, and described two round ceramics can slide on said minor axis; Said clamper is between said weft yarn bobbin and said main burner, and the weft yarn on the said weft yarn bobbin is from introducing said main burner afterbody through the back between described two round ceramics.
Compared with prior art, main jet air-flow of the present invention carries weft yarn stability measurement systematic survey means simple possible, and can effectively measure the weft yarn steadiness.
Concrete measurement effect is following:
1, weft yarn is arranged but wefting insertion not in main burner, weft yarn stretches out from the main burner spout, floats in the air-flow, and when extension elongation was L=2mm, the fill yarns float momentum was less than 0.5mm;
2, weft yarn is arranged but wefting insertion not in main burner, weft yarn stretches out from the main burner spout, floats in the air-flow, and when extension elongation L was 5mm, the fill yarns float momentum was less than 1.0mm;
3, work as weft yarn when latitude and in main burner, spray, measuring distance is 40 mm, and the fill yarns float momentum is less than 2.0mm.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. detailed description.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
