ZAX—N type air jet loom

The ZAX-N air-jet loom is a new type of air-jet loom developed and produced by Tsudakoma Industry Co., Ltd.
The ZAX-N air-jet loom is equipped with the “weaving navigation system” of Tsudakoma Industry Co., Ltd.’s proprietary technology, which enables simple operation of the loom’s professional technology and optimal weaving conditions.
Suitable weaving varieties ZAX-N air-jet loom has a rich variety of devices that can weave various fabrics. It can weave various high-grade fabrics ranging from general clothing materials to denim, pure wool fabrics, filament fabrics, and ever-changing multi-color, wide width, and high value-added fabrics.
Main mechanism The high-rigidity frame structure uses strong box-shaped frames and beams on both sides as the main body. Even when weaving heavy fabrics at ultra-high speed, its vibration suppression and durability are outstanding. The middle support frame mechanism of the rocking shaft and the rocking balancer are standard equipment, realizing smooth and powerful beat-up. Even at ultra-high speed, it can perform stable beat-up with low vibration and weave high-quality high-density fabric products. The front beam and the air storage tank are integrated into one body, and are directly connected to the new solenoid valve integrated with the manifold. The distance from the solenoid valve to the nozzle is shortened, high-speed adaptability is improved, and air consumption is reduced.
Beating-up system The narrow-width machine adopts a 4-link beat-up that has excellent evaluation in terms of high-speed adaptability. For the wide-width machine, a 6-link beat-up with excellent weft insertion time is adopted, thus achieving high-speed operation. Stable weft insertion.
FDP-AⅢ electronically controlled drum weft storage device ZAX-N adopts the new FDP-AⅢ electronically controlled drum weft storage device in all aspects. It is equipped with a yarn feeding mechanism with excellent high-speed tracking performance and active yarn separation, which can adapt to various types of weft yarns.
Stable weft insertion through shuttle control Because the secondary weft insertion at startup usually does not reach the normal speed due to the rotation speed of the loom, it is easy to cause weft insertion failures such as long wefts or poor yarn ends. ZAX-N uses a computer to control the weft insertion timing of the shuttle to prevent long weft or yarn end failures during startup.
Three-eye weft finder The reflective three-eye weft finder can effectively detect all colored yarns such as short fibers and filaments, and can perform weft insertion stably. And there is no need for a fixed reed width.
WBS Weft Brake WBS greatly reduces the peak tension that occurs at the end of weft insertion, thereby effectively preventing weft breakage and slack. The FDP sensor can be used to detect the unwinding angle of the weft yarn and control the braking timing and braking stroke with high precision. It is suitable for wide-width looms with large peak tension and yarn types that are prone to binding breakage. In addition, an automatic setting function has been added, which can be set very easily on the Navi keyboard, and it also has a pull-back function to prevent yarn end failures.
The special shedding device for yarn end treatment yarn (CC) uses a special shedding device, which can save 2 pieces of heald frames for yarn end treatment, so that the heald frame can be completely used for weaving, so it can adapt to more complex fabric weaves. And it produces effects in terms of speed and energy saving.
2/2 Selvage Special Device By converting the selvedge opening when using the selvage device or when weaving denim into a separate dedicated opening device, the load on the tissue opening device is reduced. This device is not only economical, but also effective in speeding up and saving energy.
Top-mounted temples Arrange yarn guide rods near the fabric fell and top-mounted temples on both sides to stabilize the fabric fell of all short fiber fabrics and improve the quality of the fabric. In addition, the lower part of the yarn guide rod can freely set the configuration of the auxiliary nozzles, thus further expanding the range of weaving.
Auxiliary main nozzle accelerates the weft yarn with lower air pressure to prevent damage to the weft yarn. Even under conditions that easily cause weft yarn burden, such as ultra-high speed or wide width weaving, stable operation with less weft breakage is possible. In addition to the standard type that is linked to the main nozzle, there is also a stand-alone type that can set the injection timing arbitrarily.
Stretch nozzle For fabrics that easily produce weft yarn relaxation, the stretch nozzle is very effective. This nozzle uses air to actively hold the weft yarn and prevent the weft yarn from slackening.
The ELO electronically controlled warp let-off device, which can maintain uniform warp tension, takes the loom a step further by adopting a highly rigid structure frame, a large-diameter warp beam gear, and a positive warp let-off drive shaft built in an oil bath. It achieves high speed and can more sensitively adapt to the weaving requirements of high-density fabrics. The diameter of the warp beam side disc can be selected up to 1100mm to meet the needs of large packages (the warp beam with a diameter of up to 914mm does not need to raise the loom).
There is no need to adjust the shed. The ELO electronically controlled warp let-off device can also be controlled by the computer according to the length of the loom’s downtime and the reason for the downtime, through the reversal (reversal) function of the warp beam and the cloth fell control. Function controls the appropriate position of the fabric fell. With this function, the parking stall can be removed and high-quality weaving can be performed.
The AC servo motor is used in the winding part, and through computer control, it rotates fully synchronously with the ETU electronically controlled winding device of the loom to control the density of the beat-up. Beating density can beMake settings on the Navi keyboard without swapping gears. In addition, through the linked operation with ELO, the computer work is easier to carry out.
Balloon prevention device reduces weft breaks and improves work efficiency by inhibiting weft balloons.
Instead of the previous needle-type selvedge method, the power of air is used to fold the yarn ends, so that the ZTN needleless selvedge device can prevent reed damage and wear and tear of mechanical parts caused by selvedge needles. damaged and easy to repair and maintain.
The adjustment of the selvage can be easily performed by inputting on the Navi keyboard, so anyone can easily weave beautiful selvage using the needleless selvage device.
The ZT selvedge device independently developed by Tsudakoma has further improved the high-speed performance based on the basic ZT selvage device with continuously improved high-speed performance and reliability. The weft-free yarn type is not only economical but also has a simple mechanism, making maintenance and operation easier.
Others, the air-clamped wire type solves the problem of flying flowers and can achieve high-speed and stable performance.
When the loom stops due to a weft insertion error, the loom reverses, adjusts the weaving fell, removes the problematic weft yarn APR-C automatic weft replenishing device
and resumes operation. These consecutive actions are all automatically controlled by the computer. . It can play a role in realizing unmanned operation, saving labor and improving fabric quality.
Weft yarn stretching system utilizes the active yarn catcher, main nozzle clamp and WBS weft yarn brake according to the corresponding combination of yarn types to weave elastic fabrics with high quality.
The number of revolutions of the loom can be set to 8 stages independently. Production efficiency is further improved by automatically increasing the number of revolutions that were previously limited by the PSC programmable speed controller type due to the type of weft yarn. The number of revolutions can be changed within 1 weft.
Energy-saving design The new solenoid valve integrated with the manifold uses its excellent response sensitivity to stabilize the pressure pulse while performing precise injection, achieving stable weft insertion during ultra-high-speed operation.
Power The unique super-start system of the super-start motor enables the loom to produce high output torque when starting to increase the shuttle’s beating power and prevent the occurrence of parking stalls. Contributed to improving the weaving quality of fabric products.
The empty beat-up start requires the loom to be reversed for a few picks before starting, and the same number of weft yarns will not be inserted. The PSS programmable start starts with only shedding and beat-up actions. This can correct the deformation of the fabric mouth and effectively prevent the occurrence of thinning, thinning weft bars and thin sections. Especially for high-speed operation and thin fabrics, the effect is better.
Single shuttle weft insertion start After repairing the weft yarn with poor weft insertion, weft insertion can be performed in this state and the loom can be restarted.
By reducing the forward and reverse empty beat-up, the disorder of the cloth edge can be reduced to a minimum, and the occurrence of pillow blocks can be effectively prevented.
After repair and restart, weft insertion can be started directly without beating up, thus preventing the QIS rapid weft insertion start gear from occurring.
