Main Structure of the Equipment
Rim charge auxiliary screw and recycling unit: usage to recycle the rim; recycling screw uses alternating frequency converter; screw diameter φ 105; screw heating zone number 4 zones
170 model screw extruder: usage to mix PP and additives as color master batch, antioxidant, fire retardant with certain ratio; screw size Φ 170 x 2, maximum feeding ability 630 kg/h x 2; speed 60 r/min; heating zone 7 zones; AC motor; set up high level and low-level alarm device, auto control feeding device; electrical motor of screw in mixing device is frequency converting
Screw spinning machine: usage the PP fusant go through filter, fusant pipe, and metering pump transport the fusant into spinning container and fiber comes out from spinneret; output about 14000 t/year; fiber denier 1.8 to 2.3 denier; weight range 15 to 70 GSM; switched melt filter filter ratings 250, filter area 5.5 square meter; metering pump and transmission unit pump offering quantity 300 CC x 2; spinning container heating pattern oil heating; fusant pipe heating pattern oil heating; slot suction device air pressure 1300 Pa, flux 844 m³/h; spinning component hole diameter 0.42 mm, L/D 1:4, material SUS431
Stretching device (new model): usage stretching and cooling the fiber; main technical parameter working width 3200 mm; device components include quenching chamber, up stretching channel, down stretching channel, diffuse winder tunnel etc., using double-side symmetry wind to cool fiber; stretching slit in down stretching device can adjust according to craft requirements, adjust system takes torque motor drive; the new type of upper and lower stretcher changes the characteristics of the traditional upper and middle stretcher which cannot be adjusted, making the equipment more regulated to the air volume and the width of the narrow seam, and ensuring the higher requirements of the customers for the silky degree; the height of the stretcher is lengthened, so that the non-woven fiber can be finer, so that the non-woven fabric is more even and the tension is stronger
Usage: offer carrier for fiber after stretching; main technical parameter air suction quantity 57000 m³/h; design speed ≤450 m/min; normal running speed ≤400 m/min; device components include air suction channel, sealing device, position correcting set, tension device, rack device, motor drive roller
