NovaStar, LFJ-B650, Slitter Rewinder, Working Width 600mm, Speed 180 m/min (New)

NovaStar, LFJ-B650, Slitter Rewinder, Working Width 600mm, Speed 180 m/min

Description

  1. Overview
    1. High speed rewinding machine with printing mark tracking system and web guide system.
    2. Main body includes steel plate structure; winding includes single-axis winding; cylinder automatically opens and cross cuts material; functions include length measuring and automatic speed increase.
    3. Applicable materials: mainly for rolls of gift paper, wallpaper, wall coverings, plastic film, and other fixed-length rolls.
    4. Cutting type: automatic cutting with rodless cylinder.
    5. Rewind accuracy error: 0.1%.
    6. Unwinding diameter: Φ1100mm.
    7. Maximum unwinding width: 600mm.
    8. Maximum rewinding diameter: Φ260mm (winding gas shaft diameter according to customer demand).
    9. Mechanical speed: 0-180 m/min.
    10. Whole machine backup power: 10 kW.
    11. Dimensions: 2600 × 1200 × 1600mm (length × width × height).
  2. Computer System
    1. Machine includes servo motor to control feeding.
    2. PLC touch screen automatically counts the number of meters and automatically cuts off; cross-cutting time is set at will.
    3. Whole machine is controlled centrally by PLC and uses a touch screen man-machine interface to activate all operations.
    4. System is a complete and integrated design including electricity and air aspects; incorporates complete safety protection measures.
  3. Unwinding Section
    1. Structural frame: independent unwind structure with 3-inch air shaft for pneumatic lifting.
    2. Roll width range: 100~600mm (working width).
    3. Unwinding diameter: maximum Φ1100mm.
    4. Core diameter: 76mm.
    5. Feature includes magnetic powder clutch.
    6. Tension includes magnetic powder tension control; automatic tension calculation is realized by PLC automatically monitoring winding diameter, making tension control of the film precise to the highest degree.
  4. Traction Drive
    1. Structure: timing belt drive.
    2. Active traction roller steel roller structure.
    3. High-grade bearings are used on all rolls.
    4. Twin roll-to-roll, steel-soft combination.
    5. Rubber press roll is clutched and pressure is adjusted by pneumatic controls.
    6. Drive roll diameter: Φ120mm.
    7. Rubber roll: Φ100mm.
    8. Maximum pressure of the rubber roll: 100 kg.
    9. Drive roll length: 650mm.
    10. Roll balance accuracy: ≤5g.
    11. Traction motor power: 3.8 kW.
    12. After the traction device is activated, the unwinding tension and winding tension set points can be locked, so changes do not affect each other.
    13. Use of high-grade bearings makes the roller rotate smoothly at high speed, reducing all noise throughout the whole machine.
    14. Use of timing belts makes the drive very accurate, runs smoothly, and reduces overall machine noise.
    15. Driven by servo motor; system tension is stable, transmission precision is total, operation is stable and reliable, length number is accurate, and there are no errors.
  5. Horizontal Automatic Cutting Unit
    1. Controlled by computer with rodless cylinder; material is automatically cut off when the set length is reached (cutting time is set at will).
    2. Pre-feed to the rewind: PLC signal is used to communicate with the servo motor; at the same time as the transverse cutting, the pre-feed is ready to rewind before rewinding.
    3. Pre-delivery length and time are adjusted at will by the touch screen man-machine interface.
  6. Rewinding Section
    1. Structure: single gas up shaft winding unit can be exchanged for a variety of gas expansion shafts (according to customer needs).
    2. Automatic tension control.
    3. Reel with support arm support.
    4. Support arm control is pneumatically controlled; support arms are combined during operation and automatically opened when unloading.
    5. Rewinding diameter: Φ260mm.
    6. Reel diameter: 3 inch or can be supplied according to customer needs.
    7. Motor power: 3.8 kW.
    8. Gas rising shaft can process a wide range of materials.
    9. Automatic inflation and deflation and automatic opening are all set at will by the man-machine interface.
    10. Tension is automatically calculated by the PLC to realize the taper diameter, making tension control of the film more precise.
