What is the principle and use of water jet loom
The water jet loom adopts two let-off methods: mechanical let-off or electronic let-off. Weft insertion also adopts two weft insertion methods: mechanical weft insertion or electronic weft insertion. Among them, the weft break phenomenon during the weft insertion process can automatically stop. The operation is simple, easy to understand, safe and reliable. Optional flat opening, cam opening, dobby opening.
The water jet loom is a shuttleless loom that uses a jet of water to draw the weft through the shed. Water jet weft insertion has greater frictional traction on the weft than air jet weft insertion, and has less diffusibility, which is suitable for weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, jetting the weft yarn consumes less energy and has low noise.
1. Frame: The main wall panel of the loom adopts high-density reinforced type, gray iron HT200, 340kg, the main beam adopts four reinforced L-shaped steels, the wall thickness is 12mm, and the sandblasting treatment. The whole frame is more stable and reduces the high-speed operation. The vibration guarantees the high quality and high output of the fabric. At the same time, the large wall panel, the middle wall panel and the side cover are tempered to make them not deformed.
2. Shedding mechanism: the size of shedding connecting rods, heald shafts and other parts is enlarged, double ribs and heavy heald frames are used to ensure stable and reliable warp shedding and clear sheds during high-speed operation and weaving medium and thick fabrics.
3. Weft detection mechanism: The sensitive photoelectric weft detector can accurately detect from raw yarn to strong twisted yarn, from low-denier yarn to high-denier yarn, and stop the weft in time to prevent weaving defects.
4. Edge support device: The cloth side support barbed shaft is changed from three rows of needles to five rows of needles. The size of the cloth side support rod and the cloth guide angle is widened. It is special for Ssangyong machine. smooth.
5. Selvedge structure: The selvedge form is rope-shaped, the selvedge is fastened, not easy to loosen, the thickness is basically the same as the ground texture, and there is no color difference after dyeing. Using aluminum alloy planetary gear selvedge mechanism, light weight, low vibration, suitable for high-speed operation. Nylon gear ring is used to reduce noise and easy to replace.
6. Aluminum alloy parts: all anodized hard film treatments such as suction pipe seat, selvedge gear, etc., are beautiful and wear-resistant. The sley and sliding seat are changed from aluminum alloy parts to stainless steel parts, which not only increases the strength, but also increases the corrosion resistance.
7. Centralized oil supply: convenient operation, simplified equipment lubrication and maintenance, and centralized turbidity adding system can ensure the lubrication of equipment running normally.
8. Beat-up mechanism: adopts inertial beating-up with a crank connecting rod mechanism. The crankshaft is processed by high-frequency quenching and other special processes to improve wear resistance, hardness and strength. The diameter of the rocking shaft is enlarged, the seamless steel pipe of ∮114×lOmm is adopted, and the forged multi-sley foot is used to enhance the strength and ensure the life. The sley and sliding seat are made of stainless steel, which improves the beating force, and can weave high-density and medium-thick fabrics with tight and plump fabrics.
9. Side cutting device: using ceramic or cemented carbide blades, which are sharp and wear-resistant. Equipped with imported connecting rod end bearings, it can cut the weft accurately and accurately regardless of the thickness of the weft.
10. Bearings, crankshaft: Mainly adopt original imported bearings from Japan NSK. Quenching the crankshaft further improves the wear resistance of the crankshaft and prolongs its service life.
11. Warp let-off mechanism: special type for twisted fabrics, ultra-fine and high-density fabrics, special processing, professional manufacturer manufacturing, fine assembly. Cooperate with the advanced drape-type continuously variable transmission to adjust the warp let-off amount, and the friction plate pressure device prevents the warp let-off and unwinding fluctuation, is suitable for the large tension of medium and thick fabrics and ensures the stable warp tension.
12. Optional electronic winding: compact design, large output power, easy to adjust: automatic operation of various fibers: to ensure that the synchronization is always maintained during the weaving process.
13. Optional electronic warp let-off: to keep the warp tension stable, meet the needs of a variety of fabrics, improve the grade of the fabric, change the fabric variet
