PRODUCTS DESCRIPTION

ZA216eZA218e type air jet loom, which has introduced into high advancedtechnology from Japan by Tsudakoma Corp., is developed by JWTM XianYang TextleMachinery Co. ,Ltd. By adopting advanced multi-microprocessor electroniccontrolling technique, large-sized IC, and multilayer circuit plates, itminimized circuit plates
while improve the whole system reliability. Its strong intelligence iT-boardmakes the machine more intelligent and operative. Using all kinds of shedding,the machine reduces more cost while increases productivity and can weave highvalue fabric.

ADVANTAGES

● Electric Control

As a man-machine interface of electronic controlling system, iT- board isresponsible for data input, management function establishment, auto- parametersetting up, and malfunction selfdiagnose,by which makes the operation simpleand convenient, and upgrades automation level of whole equipments.

The diagram show flight curve of the weft yarn, on which the parameter ofthe weft yarn can be changed arbitrarily, and the flight of the weft can beadjusted, supervised and controlled.

Input the yarn counts or other parameters on the machine, it can calculatecraft data automatically. It is convenient to change the species of fabric andadjust the loom.

The memory time of daily and class report got increased from 7 days in thepast to 30 days at present and can be demonstrated by various ways as curve,pillar diagram, data...etc..

● The motion for high speed

1.　Strong Frame Structure

　　Using strong boxwall board of both sides, beating motion by using rocking shaft mid-supporterto ensure wide weaving range and also make the small noise and less vibrationat high-speed operation.

2.　Rocking shaft mid-supporter motion

　　Rocking shaft isfullness steel which using mid-supporter, this motion improves the rigidity ofthe beating. They ensure smooth and powerful beating even at high speed.

3.　Strong four-bar linkage beating motion

　　ZA218e uses strongfour-bar linkage beating motion, It is effective for weaving heavy and highdensity fabrics, It eliminate stop marks.

4.　Drive Power

The machine uses super start motor. The rush start system develops bydelivers 12 times torque at starting enabling beating power for the first pick,also it uses more torque electromagnetic brake for eliminating stop marks.

● Shedding

1.　ZCM3 negative cam

　　It is suitable forsuper high speed, it can make warp yarn shedding with high speed and strongadaptability.

2.　Positive cam

　　It is suitable forweaving heavy and width fabric shedding motion. It runs at high speed andsteady warp yarn shedding.

3.　Dobby shedding

　　Can choose dobbydevice for mechanical/ electric, negative/ positive and down installed / upperinstalled.

● Weft Insertion

1.　Main nozzle

　　Adopt L type mainnozzle which saves energy and has high speed, obtain a higher speed atlower pressure, improved the effective of weft insertion, reduce the airconsuming greatly.

2.　AJC weft automatic control system

　　ZA216e／ZA218e　is equippedwith AJC weft insertion automatic equipment. This equipment can control thetime which weft arrive the feeler, through weft time control can compensate theweft changes, especially weft yarn which tension change too much from full coilto small coil, the result is obvious and weft yarns are stable.

3.　Sub nozzle timing control according color

　　For different kindof weft yarns, use corresponding sub-nozzle to control the weft yarn to ensurethe loom running stably, have not only economize the energy but also improvedthe quality of products.

4.　Sub-nozzle support control

　　When weft yarn arechanged and loom start again and also the heavy change take place in the reachangle of weft yarn , the equipment postpone the ejective
time of sub nozzle automatically , make the weft insertion stable and keeppremium product quality.

5.　Stretch nozzle

　　To the fabricwhich is apt to relaxed and elastic fabric, the stretch nozzle is veryeffective. This nozzle controls the weft yarn effectively with the air toprevent the weft yarn being relaxed.

● PSS programmable start

1.　Empty beating start

　　Reverse a few weftbefore the loom start, the same count of weft yarns don't insert weft, and itonly start at the motion of shedding and beating. So it can modify thedistortion of the woven hatch, efficiency prevent from scarce and thickblock and wave veins. Very much operate to the high speed and high-densityfabric, its result is the best.

2.　Single shuttle weft insertion start

　　After mending thebreak weft yarn, it can insert weft and restart the loom. By reducing thereversal empty beating, it can reduce weaving shedding trouble best of all,eliminating stop marks effectively.

3.　QIS speed weft insertion

　　When the loomrestart, It can insert yarn directly without beating to prevent from producingstop marks.

● Let-off BPC contorl

　　When the loomstopped,lock the motor of let-off,prevent from stop mark because of warp beamskid.
