NovaStar, BL154, Film Blowing Machine, 600 to 1200mm Width, 120kg/hr Capacity, 65mm Screw (New)

NovaStar, BL154, Film Blowing Machine, 600 to 1200mm Width, 120kg/hr Capacity, 65mm Screw

Description

  1. Overview
    1. Suitable materials: LDPE
    2. Screw diameter: Φ65 mm
    3. Screw L/D length: 30:1
    4. Blowing film driving motor: 35 kW with inverter
    5. Maximum extrusion output: 120 kg/hr (LDPE)
    6. Die size: 250 mm (LDPE)
    7. Width of the blowing film: 600 to 1200 mm
    8. Thickness of blowing film: 0.009 to 0.20 mm
    9. Weight of overall: 4.5 t
    10. Cover dimensions (L x W x H): 5.5 x 4 x 6.5 m
  2. Extrusion Unit
    1. Main motor: provides driving force for the screw; 3 grade, horizontal type; power: 30 kW; rational speed: 1400 rpm; CE certificate, ISO standard; guarantee period: three years; standard voltage supply: 380 V, 50 Hz, 3 phase; Brook (UK)/Siemens (DE)/GE (USA) as customized
    2. Screw and barrel: screw Φ65; material: double alloy; L/D: 30:1; origin: Zhoushan; technical support: NovaStar; raw material of barrel: 38CrMoAlA or SACM645; nitriding depth: 0.8 mm; nitriding hardness: 1000 HV; chromed hardness: ≥950 HV; chromed thickness: 0.08 mm
    3. Fixed die head: customized flow channels are used to extrude 1 layer film materials; size: 250 mm; raw material: No. 40 steel, forging and heat treating; composed by die core, die body, die ring and heating ring; machining center: LG Mazak, higher accuracy; keeps film thickness average and equal, and film quality is shining; custom produce, according to different type raw material, supply different design die head
    4. Air ring: provides uniform air flow for blown film bubbles; type: double lips air ring; raw material: aluminum; compact structure to increase the discharge of air; equal air discharge to make the film cooling faster and film bubble stable, no moving, to get final product flat
    5. Meter weight control and auto loader: meter weight control provides accurate control of the extruder screw and haul-off to ensure the extrusion products (thickness/weight per meter) are stable and reliable; auto loader uses vacuum suction to automatically extract raw materials into the hopper; continuous and uninterrupted feeding is more labor-saving and convenient
    6. High speed cooling blower: provides stable and strong airflow to the air ring; high pressure air wind cooling, less noisy but high cooling speed; cooling the film fast to keep the quality of the film; cooling blower: 11 kW; motor guarantee period: three years; high quality wind pipe, can bearing high temperature from the die head
  3. Traction Unit
    1. Traction rubber roller: polyurethane material (long life, not easy to leak); width: Φ250 x 1300 mm
    2. Embossing roller: computer engraving molding, clear lines and hand feeling well
    3. Steel roller: full section chrome plating, long life, not easy to rust
    4. Traction: equipped with a flattening roller, can make the film higher flatness, not easy to wrinkle
    5. Motor: frequency control, stable speed, low energy consumption; power: 2.2 kW
    6. Plate: mahogany material, to static electricity does not scratch
    7. Edge inserting device: one random size
  4. Winding Unit
    1. Winding type: double winding
    2. Traction: makes the film airtight
    3. Winding: friction type single winding
    4. Expansion force module: torque motor control
    5. Arc shaped roll: with a flattening roller to make the film even
    6. Air shaft: 4 pcs
  5. Electrical Appliances
    1. Inverter brands: Delta (Taiwan), Schneider (France), ABB (Switzerland)
