Technical Overview

The 20g-500g Washing Powder Vertical Packaging Machine represents China's advanced automated filling technology, specifically engineered for granular and powdered detergents.

This servo-driven system combines gravimetric auger filling (±0.3% accuracy) with quad-seal pouch formation, achieving production speeds of 50-70 pouches/minute.

Its modular design features food-grade SUS304 stainless steel contact surfaces and complies with ISO 9001/CE safety standards.

Core Specifications

• Capacity Range: Configurable for 20g-500g portions with quick-change auger kits (standard 25mm/50mm screw diameters)

• Film Compatibility: Laminated PE/PP rolls (150-300μm thickness) with maximum 400mm roll diameter

• Weighing System: Loss-in-weight feeder with dynamic compensation for density variations

• Sealing Mechanism: Four-stage heated jaws (120-200°C adjustable) with water-cooling for crisp seals

• Power Requirements: 220V/50Hz, 4.2kW (servo motors reduce energy consumption by 25% versus stepper systems)

• Dimensions: 1800(L)×1200(W)×2500(H)mm footprint for compact production lines.

Advanced Features

• Anti-Caking System: Integrated vibratory sieve breaks clumps during filling

• Nitrogen Flushing: Optional gas injection extends detergent shelf life

• Smart Registration: CCD camera ensures ±0.5mm print alignment accuracy

• Data Integration: OPC-UA protocol enables real-time production monitoring.

Operational Workflow

Pre-Production Setup

• Material Loading: Pour bulk detergent into the 80L stainless steel hopper;adjust auger speed based on powder flow characteristics

• Film Mounting: Thread pre-printed film through tension rollers and forming collar;verify photoelectric sensor alignment

• Parameter Input: Configure pouch dimensions (typical 100×70mm for 200g), sealing temperature (160°C for PE), and batch quantity via 10" HMI touchscreen.

Production Cycle

• Pouch Formation: Film converts into tubular shape via forming collar, sealed vertically by continuous heat jaws

• Precision Filling: Twin augers (main + micro-feed) deliver measured portions;load cells verify weight every 5 cycles

• Final Sealing: Cross-sealing jaws create quad-seal pouches while simultaneously separating finished units

• Output Handling: Motorized conveyor transfers pouches to checkweigher or secondary packaging station.

Maintenance Protocols

• Daily: Clean residual powder from auger/flange surfaces;inspect sealing jaw contamination

• Weekly: Lubricate chain drives with NSF-H1 grease;calibrate load cells with test weights

• Quarterly: Replace wear parts (auger flights, transport belts);check electrical grounding.

Troubleshooting Guide

Frequent Operational Challenges

• Powder Leakage During FillingRoot Cause: Worn auger flights or improper flange gasket seating

  Resolution: Replace auger segments;apply food-grade silicone to gasket surfaces

• Seal WrinklingRoot Cause: Film misalignment or uneven jaw pressure

  Resolution: Adjust forming collar position;recalibrate jaw closure force to 25N/cm²

• Weight DriftRoot Cause: Electrostatic buildup affecting load cells

  Resolution: Install ionizing bars near hopper outlet;ground machine frame.

FAQ Section

Q1: Can it handle scented detergents without cross-contamination?

Yes, the stainless steel construction allows CIP (Clean-in-Place) sanitization between batches using food-grade detergents.

Q2: Minimum film width requirements?

150mm minimum for 20g sachets;300mm recommended for 500g stand-up pouches.

Q3: How to integrate with existing bagging lines?

Standard 500mm height conveyor interfaces accommodate most checkweighers and robotic palletizers.

Q4: Warranty coverage for abrasive formulations?

Standard 1-year warranty excludes auger wear;hardened steel screws available for abrasive detergents.

Sustainability Features

• Energy Recovery: Regenerative drives convert deceleration energy into auxiliary power

• Material Savings: Precision filling reduces detergent waste by 1.5% annually

• Recyclability: 95% machine components demountable for end-of-life recovery.
