textile machine air jet loom

1.The main features:

The design of machine structure is more reasonable, more sensitive to minor changes of tension; makes inch more to maintain certain tension as weft tension changes, eliminating uneven distribution of warp due to stop and restart.

This air jet loom adopts the weft insertion method of combination of fixed main nozzle+swing main nozzle+auxiliary nozzle+double feeler;it is also characterized by such features; double-sided four or six shedding lever beating system, positive cam electric jacquard system(enlarging the production scope of machine), ELO, electric weft insertion, ETU, slow frequency conversion system, auto weft-searching auto-stop upon broken warp functions. It therefore provides more stable performance
This model has advanced design and stable performance, solving problems like stop block, mechanical stop, missing weft and missing warp, suitable to products as grey cloth, light or medium-weight and jeans etc.

Oil bath lubrication is applied in most transmission parts like main powertransmission, let-off, take-up, beating and shedding system. Central oil injection is done to other parts, which prolongs the period of oil injection , more easy for maintenance.

Let-off and take-up system

ELO: electric let-off
Overally yarn tension will be detected by tension sensor, then signal will be processed by CPU, which will control the feeding of warp according to the real-time cloth roll diameter, in the same time, servo motor will controlled to form even tension to eliminate unbalanced distribution of warp and weft in the start run.

ELO: electric take-up
AC servo motor is used in ETU system and controlled by computer which enables it to synchronize with machine and control beating density. Weft density can be set simply on touch screen, no need to replace change gear. What is more, by linkage with ELO, stop block is effectively reduced

Techinical data of Air jet loom OBT-WJA700
Weft insertion device	Electric feeder Electric feeder is able to weave a wide variety of yarns. It is able to automatically adjust to meet the feeding characteristic, therefore the fluctuation of yarn tension is reduced to the lowest and weft insertion is made more smooth and stable. The optical feeler of two probes is not only able to detect short weft or missing weft, but to detect the occurrence of broken weft and over-long weft.
	Auxiliary main nozzle Weft will be inserted at low air pressure, to prevent damage to weft. therefore, the machine is able to main stable performance during high speed running or super wide weaving situation where weft is easy to get fatigue.
	Stretch nozzle Stretch nozzle is especially useful to process loose-easy yarn. The nozzle works by pressing air to hold weft , instead of getting loose
Bitmap Man-computer interface design	1.Big size touch screen is used, easy for operation. Man-computer interface is strengthened. It is able to diagnose existing problem on its own, say, display the reason of stop.
	2.The operator is able to change and type in new setting specification simply on the touch screen.
	3.Certain specification can also be stored in the computer via memory card
	4.If one sets the machine to stop when certain length of cloth is finished, cloth inspection process will be finished smoothly.
	5.Personal performance of one operator can be analyzed according to production records stored.
Bitmap Bitmap Shedding mechanism in loom	Different shedding types are available, like positive cam shedding and dobby shedding. Plain, stain and twill fabric. The shedding is clearer, weft passes easily, therefore, production efficiency is increased. Cam gear box is lubricated in oil bath, more stable.
	1.Negative cam shedding: works with 8 pieces of heald frame at most. This cam box is designed with excellent opening, suitable to run at high speed, also easy to replace with new cam. It is suitable to produce such fabric as plain, twill and satin.
	2.Crank shedding: works with 4 pieces of heald frame, suitable to produce high quality plain fabric.
	3.Positive cam shedding: works with 8 pieces of heald frame at most, suitable to produce such fabric as plain, twill and satin. It is most mounted on heavy-duty or super-wide typed water jet loom.
	4.Dobby shedding: working with 16 pieces of heald frame at most, suitable to produce such high-added value fabrics as plain , twill, stain and small jacquard.
