ZW type water jet loom
The ZW408 water-jet loom is an improved version of the ZW405 water-jet loom produced by Tsudakoma Industrial Co., Ltd. The breeding type also includes ZW408C type.
Suitable for weaving varieties ranging from general fabrics to medium-heavy high value-added fabrics.
The main structure has highly rigid box-shaped frames on both sides, which can reduce vibration during high-speed operation. Due to the reduction of vibration, further stable weft insertion and beat-up can be achieved, thereby ensuring the high quality of the fabric.
The main driving part is arranged in an oil bath environment, thereby achieving further stable high-speed operation.
Stable weft insertion performance and soft weft insertion Adopt a new nozzle that improves the concentration of the jet water to achieve weft insertion when the opening is small. In addition, only a small amount of spray water can be used even in ultra-high-speed operation, thereby achieving soft weft insertion that is beneficial to the weft yarn. Not only can it improve the quality of the fabric, but it can also reduce water consumption.
The stable cloth fell adopts a strong frame structure and a highly rigid let-off and take-up mechanism to make the cloth fell position more stable, so that the weaving range ranges from light and thin fabrics to medium-heavy fabrics, from low-density fabrics to High-density fabrics have been greatly expanded. Even when the loaded dobby is running, the vibration can be controlled very slightly, so fabrics with complex structures and unbalanced weave fabrics can be woven stably.
Calm weft insertion Through the improvement of the beat-up curve, the weft flying angle is increased. This makes the weft insertion of thick-count strongly twisted yarn and new synthetic fibers more stable, and can weave high-quality differential fabrics. At the same time, the weaving effect of fabrics with unstable warp openings or fabrics that are prone to warp relaxation has also been greatly improved.
PF-type nozzle has been improved on the basis of the previous P-type nozzle, further improving the clustering of the sprayed water, achieving stable operation with a smaller opening and a smaller amount of water, and even at high-speed operation. Beneficial for soft weft insertion of warp and weft yarns. Especially in the high-speed weaving of single-color taffeta, it can play a huge role in improving fabric quality.
SDP length measurement and weft storage device The new SDP is a single-color dedicated length measurement and weft storage device. Since there is no need for a blower to store the weft yarn, energy can be saved significantly. Moreover, the tension given to the weft yarn is small, and the error in length measurement can also be controlled at a low level. Due to the improvement of the balloon state during weft insertion, the range of applicable yarns has also been significantly expanded.
RDP-A length measurement and weft storage device Because the maximum tension given to the weft yarn is small, it can also ensure the high quality of the fabric in high-speed weaving of single-color fabrics. Not to mention conventional yarns, even twisted yarns, Taslan yarns, knotted yarns, looped yarns, etc., can be adapted to various differentiated fabrics.
OPF fully electric weft finder The fully electric weft finder with a simple and compact structure can accurately detect raw yarns to strongly twisted yarns, from fine to coarse yarns, achieving high-speed and stable operation.
FDP-H length measurement and weft storage device The new FDP-H, which is computer-controlled and easy to operate, considers reducing the tension of the stored weft yarn, so it can realize fine yarns, untwisted yarns and even coarse yarns. , Stable storage of strong twisted yarn.
The control of electric thread clamps, electromagnetic switching valves, etc. can be input and managed on the IT keyboard together with the timing of the weft stop pin of the weft feeder.
The adjustment of the weft feeder head is simpler in terms of software and hardware, and it also improves high-speed tracking. It is also equipped with a comfort sensor and a weft break sensor on the weft feeder, enabling further high-quality weaving.
2C nozzle partition plate can stabilize the front end of the weft yarn exposed from the nozzle part, thereby preventing the weft yarn and the weft yarn from being entangled with each other.
Super-start motor Super-start motor realizes ultra-high magnification of the starting torque of the loom. It can prevent the weft yarn from slackening during parking stall and weft insertion. The large-capacity electromagnetic brake directly connected to the crankshaft realizes precise positioning and parking of the loom.
Fabric let-off
The reinforced gearbox and double-roller let-off are suitable for light to ultra-heavy fabrics and can improve the quality of the fabric. Whether it is the MLO mechanical let-off equipped with a ring-cone speed changer or the easy-to-operate ELO electric let-off, both are foolproof in preventing parking stalls.
WBS weft braking greatly reduces the peak tension that occurs at the end of weft insertion, which can make the wrinkles of strongly twisted yarn fabrics uniform during high-speed operation. It can also prevent tight and loose wefts in fabrics such as low-elastic yarns during weaving.
3-color free selection of weft The combination of 3-color free selection of weft and double pumps can adapt to different types of fabrics with different counts, and can further expand the weaving range.
Electric weft pull-back device When weaving a part of the fabric, the front end of the weft exposed from the nozzle is straightened back, thereby preventing the weft and weft from being entangled with each other and making the weft insertion more stable.
Double pump
Combine two kinds of weft yarns with large differences in yarn count, thickness or characteristics,Cooperate with the best weft insertion method to achieve stable
high-speed operation. It is suitable for high-speed and stable operation of high value-added fabrics of different types and yarn counts.
2-color swing-type nozzles The swing mechanism with a unique structure can enable each nozzle to insert weft at the best position, thereby making the loom operation more stable. Moreover, the beating stroke can be as short as that of single color, so vibration and power consumption can be reduced, which is beneficial to high-speed operation.
CCL no weft-catching edge yarn is used to create the selvedge on the side opposite the nozzle without using weft-catching edge yarn through the nozzle set on the outside of the fabric. It can avoid failures caused by weft-catching edge yarns and improve operating efficiency.
Separate driving device for yarn end processing yarn The yarn end processing yarn is opened with a special rod. The dobby frame can be used entirely for cloth weaving, and is also conducive to high speed, expanded weaving adaptability and energy saving.
Special device for elastic yarn The weft catcher on the side of the nozzle can adjust the holding force to prevent the weft yarn from coming out of the nozzle. The tension plate on the side opposite the nozzle can maintain the tension of the weft yarn, thereby weaving a uniform elastic fabric in a stable state.
Front fabric path tilt type By inclining the fabric path from the cloth fell, even when weaving unbalanced weave fabrics such as double fabrics, the up and down movement of the cloth fell can be avoided and stable weaving can be achieved.
Contact IT keyboard (optional) Newly developed contact IT keyboard. The settings of ELO electric let-off, ETU electric take-up, and FDP-H electric drum weft storage can be performed centrally on the IT keyboard, and the setting of the preventive parking gear has also become easier. The operating status of the loom can also be monitored.
