ZAX air jet loom
The ZAX9100 air-jet loom is a new generation of air-jet loom developed by Tsudakoma Company with the goal that anyone can easily use professional technology to weave high-quality fabrics at high speed and efficiently.
This model has achieved technological breakthroughs or improvements in the frame structure, beat-up, weft insertion, let-off and take-up mechanisms. Coupled with the powerful functions of Tsudakoma’s first weaving navigation system, this type of weaving system The machine has become the most outstanding air-jet loom at present.
Suitable weaving varieties Equipped with various effective auxiliary devices, it can weave everything from general clothing materials to light and heavy denim pure wool fabrics, filament fabrics, glass fiber fabrics, as well as multi-color, wide width, high value-added fabrics Fabric.
Main structure The traditional high-stability structure of box-shaped wall panels and beams on both sides is newly designed by computer three-dimensional careful analysis, plus a new concept of eccentric beat-up rocking shaft with small inertia moment and hollow steel reed holder The adoption of this technology achieves a more reasonable, smooth and powerful beat-up, while reducing the load in the power oil bath and greatly suppressing vibration, enabling it to have excellent performance in high-speed weaving of difficult fabrics that previous looms were unable to achieve.
The front beam and air storage tank are integrated and directly connected to the new electromagnetic. Each two auxiliary nozzles are equipped with an air valve, which further improves high-speed adaptability and effectively reduces air consumption.
Weaving Navigation System This system is the first of its kind for Tsudakoma Company. It incorporates the rich experience and professional technology accumulated by Tsudakoma Company for many years. Through simple input on the “navigation keyboard”, users can simply perform professional tasks. Technical level weaving. This system can guide the loom to achieve optimal operating status during the operation of the loom. At the same time, the maintenance navigation function in the system can guide users to perform necessary maintenance operations in a timely and efficient manner, and when a loom fails, it can accurately and quickly find out the cause of the fault and troubleshoot it. Through this navigation system, users can also query the loom. How to use the machine and details of spare parts.
This system has more powerful learning and updating functions. In the future, you can obtain free upgrade services provided by Tsudakoma Company at any time, and share its new development results with Tsudakoma Company.
Humanized design This model has made new improved designs in many places to improve the convenience of operation. First, the height and depth dimensions of the frame have been improved, the operating distance has been shortened, and the pressure control device has been changed to a simple one. In the upper position of the operation, the positive let-off device originally located on the inside is changed to the outside, the types of tools used are unified, and a quick handle for lifting the cloth pressing roller is installed. In addition, the navigation system also has an automatic setting function, which can quickly improve the parking gear function, etc.
Weft insertion system adopts 4-link beat-up for widths below 250cm, and 6-link beat-up for wide widths with sufficient weft insertion time, thus achieving stable weft insertion at high speeds.
FDP-AⅢ electronically controlled drum weft storage device ZAX9100 loom is equipped with the new FDP-AⅢ electronic weft storage device as standard. The yarn feeding mechanism with positive yarn separation can easily weave pure wool fabrics with long and hard hairiness or adapt to other unusual fiber weft yarns. The preparatory winding amount of other weft yarns is more than three times greater than that of the previous weft feeder, thereby greatly improving the tension stability during unwinding of the weft yarns and achieving stable operation.
Stable weft insertion through the control of the first shuttle ZAX9100 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, greatly reducing the weft detection error rate of traditional weft finders during weft insertion of colored yarns, thus Improve efficiency.
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 standard sensor of FDP-AⅢ can be used to control the unwinding angle of the weft yarn and control the braking timing and braking stroke with high precision. And its strong pull-back function effectively prevents yarn end adhesion.
Special shedding device for yarn end treatment sand (CC) Using a special shedding device, 2 heald frames for yarn end treatment can be omitted, so that the heald frame can be fully used for fabric tissue, reducing the load of the shedding device. This device Not only is it economical, but it is 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.
Auxiliary main nozzle accelerates the weft yarn with lower air pressure, which can prevent damage to the weft yarn and enable stable operation even under conditions that easily cause weft yarn burden, such as ultra-high speed or wide width weaving. There are two types: the standard type that can be linked to the main nozzle, and the stand-alone type that can set the injection timing separately.
Stretch nozzle Stretch nozzle is extremely effective for fabrics that easily produce weft yarn slack. According to the degree of slack of the fabric, there are three options: horizontal blowing type, back blowing type and reed tooth embedded type.
An AC servo motor is used in the winding part, which is controlled by a computer to completely synchronize it with the loom. ETU electronically controls the winding to control the beat-up density. The beat-up density can be adjusted in “Settings can be made on the “Navigation Keyboard” without changing the weft density gear. Other linkage operations with the ELO electronically controlled warp let-off make the machine operation easier.
It can maintain uniform warp tension during high-speed operation It can also be highly sensitive to the ELO electronically controlled warp let-off weaving requirements of high-density fabrics.
No need to adjust the shed. The ELO electronically controlled warp let-off device can also be extended by the computer according to the length of the loom’s shutdown time and the reason for the shutdown. Through the control of the warp beam and the cloth fell control function, the cloth fell is in the best position. This function can effectively remove and improve the parking stall.
The anti-balloon device can suppress the weft yarn balloon. Reduce the interference between broken weft and weft yarn storage device.
Instead of the previous needle-type selvage method, air is used to fold the yarn end, thereby preventing the ZTN needleless selvage device from being damaged by the selvage needle. The resulting reed damage and wear of mechanical parts are easier to maintain. The adjustment of the selvedge can be simply set through the “navigation keyboard”. With this selvage device, anyone can easily weave beautiful selvedges.
When the loom stops due to a weft insertion error, the loom is reversed, the weaving fell is removed, and the APR-C automatic weft replenishing device is used to remove the problematic weft yarn and repeat the operation. This series of actions is all automatically controlled by the computer. It can realize unmanned operation, save labor and improve fabric quality.
Weft insertion control adopts AJC weft insertion automatic control function and FIC weft insertion fuzzy control function, and the injection timing control function and the injection pressure control function work together. Coupled with the independent color separation control and support control of the auxiliary nozzle, the weft insertion of any weft yarn can reach the ideal state.
Through this device, the loom speed can be changed freely, and multiple settings can be set within the same fabric. The speed of the PSC programmable speed control device can be changed within 1 weft, which can not only adapt to fabrics with different specifications of spinning yarns, but also can be used for high-speed weaving at a high-efficiency balance point on conventional fabrics.
Empty beat-up start: After the loom is reversed for a few wefts before starting, the PSS programmable program starts the weft without inserting the same number of wefts. It starts with only shedding and beat-up actions, so that the cloth fell can be corrected. deformation, effectively preventing the occurrence of thin wefts and thin wefts, especially for high-speed operation and thin fabrics.
Single shuttle weft insertion start After repairing the weft yarn with poor weft insertion, it can be used in this state. Perform weft insertion and restart the loom.
By reducing the forward and reverse empty beat-up, the disorder of the cloth mouth can be reduced to a minimum, and the occurrence of pillow blocks can be effectively prevented
after repair. When restarting, the weft insertion can be started directly without beating up, thus preventing the QIS quick start in the parking gear.
Using the key input of the navigation keyboard, the repose angle and phase difference can be freely set, including the servo ESS electronic opening. The entire transmission system, including the engine, has been completely renovated, further achieving higher speeds. It can adapt to 16 types of heald frames. It is possible to weave high-quality fabrics that combine the characteristics of the multi-frame weave of the dobby and the cam repose angle, and because the weave can be changed in an instant, the variety can be quickly changed.
