JA60 AIR-JET LOOM

To go with the trend of market development, and to meet customers' requirements for high-quality and diversification of air-jet looms, Dongjia team elaborately forged and launched higher-speed, more stable and more energy-saving JA60 all-powerful series air-jet looms based on the idea “to break the rules, you must first master them”.

This machine is of high  electromechanization, more excellent in high-speed, low vibration, energy-saving and less manpower,applicable to weave products from common garment fabrics to various industrial fabrics ranging from denim, woollens, glass fibers, tire fabrics, airbag fabrics, etc. As the new generation of weaving equipment, it has great development potentiality.

MORE INTELLEGENT

High reliability touch screen, new type communication technology and high electromechanical integration design make machine realize high intelligence.

MORE EFFICIENT

New type integrated side frames, the beating-up mechanism with good balance performance, and the excellent weft insertion system complement each other, applicable to various yarn counts, and at the same time help realize the weaving of high-speed, low vibration and high quality.

MORE CONVENIENT

Full consideration of the convenience for the operation of workers in the course of design, external loose warp device, automatic central oil supply system, and friendly man-machine interface make machine more humanization, and embody the superiority in the course of application.

MORE ENERGY-SAVING

New type energy-saving weft insertion system, shorten air path, increase jet sensitivity and reduce air consumption.

MORE STABLE NEW TYPE FRAMEWORK

Integrated side frames innovatively designed, with high rigidity cross rails and mid-supporters to form ultra-high strength frameworks, thus make looms keep low vibrations while its high-speed running. Has applied for national patent for the integral type side frames (Patent No.: 2016201698706) .

MORE EFFICIENT BRAKING STABLITY

Adopt double braking disc electromagnetic device to realize loom’s precision positioning, thus to efficiently prevent stop marks and improve fabric qulaity. Now applying for national patent for this device.

ADJUSTABLE EXTERNAL LET-OFF MECHANISM

Equipped with external loose warp mechanism, which make operation more simple and convenient; eccentric device with graduation marks can make loose warp amount adjusted freely among 0-6mm to meet the requirements of more fabrics. Has applied for national patent for this mechanism (Patent No.: 2016201701215).

MORE BALANCED PERFORMANCE BEATING-UP MECHANISM (Option)

Equipped with new type energy-saving weft insertion system, which can shorten air path, increase jet sensitivity and reduce air consumption. Has applied for national patent for this mechanism (Patent No.: 2016201698829).

MORE ENERGY-SAVING NEW WEFT INSERTION SYSTEM (Option)

The user can select the sub nozzle electromagnetic valve to control the sub nozzle by adopting one to one form, which can help reduce the injection time of sub nozzle, thus to further save air consumption.

ADJUSTABLE SUPPORT PLATE (Option)

Adopt adjustable support plate, whose length can be adjusted according to the fabric reed width, and the support plate needn’t be cut off, thus to greatly shorten the time of change; this support plate can be extended to the reed groove, with its distance to the cloth fell no more difference comparing with the bracing, and also can play a supporting role, suitable for the vast majority of fabric weaving. This mechanism is the user's optional configuration (now applying for national patent).

CLEAR SHEDDING

While ensuring the shedding amount, make the position of heald frames as close to the cloth fell as possible, so as to have the shedding clearer. In order to improve the stability of the loom when its high-speed operation, we optimize the design of warp position line, and shorten the beating-up stroke. Through the above optimization design, the power consumption can be saved more.

STABLE BEATING-UP MECHANISM

The 6-link rod beating-up mechanism based on computer aided optimum design can increase the dwell time of sley at the back to realize stable weft insertion while high-speed operation, suitable to high-speed or wide loom. Optimally-designed 4-link rod beating-up mechanism is of short stroke and small vibration, and can effect strong beating-up while high-speed operation, suitable to high-speed narrow loom.

ELECTRONIC LET-OFF MECHANISM

Adopt servo motor driving technology to accurately measure and keep warp tension, and reduce the fluctuation of warp tension; adjust the tension automatically while loom starting to eliminate the tension change in the course of stopping to avoid stop marks and ensure fabric quality.

ELECTRONIC TAKE-UP DEVICE

Adopt servo motor to ensure complete synchronization of the take-up and looms, control the pick density of fabric through computer control. the pick density of fabric can be set freely on the touch screen instead of changing gears. additionally, through linkage operation with electronic let-off, the adjustment can be effected more easily.

AUTOMATIC CENTRAL OIL SUPPLY (Option)

The automatic central oil supply lubricating system can set the running time and stopping time of oil pump automatically, and it’s equipped with alarm device to ensure the normal running of lubricating system. This system reduced labor intensity and can effeciently increase the service life of spare parts.

NEW TYPE ELECTRICAL CONTROL SYSTEM

Large-screen color LCD touch screen and human interface are fixed to display some information such as running status, fault analysis, technological parameters, etc. on the screen, convenient for operation; the USB communication interface is fixed to input various setting parameters into other looms. weaving guidance system can monitor the working status of looms at any time and be used to set the optimum technological parameters according to loom conditions and fabric technology, further improving the stop mark preventing function of looms and increasing the quality of fabrics.

APPLICATION OF NETWORK FACTORY AND THE REMOTE CONTROL TECHNOLOGY

Looms and the factory interior are connected by Ethernet to realize two-way communication between looms for convenient to transmit technological parameters. At the same time, the communication between looms and computers can be realized for convenient to collect the data and visit the looms through Internet to achieve remote control and diagnosis, which will be base for digitalized and network factory.

PNEUMATIC TUCK-IN SELVAGE DEVICE(Option)

Electronic & pneumatic tucked-in device,which can directly tuck weft ends into selvedges to achieve clean ones. for electromagnetic air flow is adopted to realize weft end tucked-in, high-speed weaving can be achieved. the tucked-in device is fixed not only for left and right edge of single width fabrics, but also for double width or multi width clean selvedge fabrics.

DOUBLE BEAM MOTION(Option)
