Product Overview

The Automatic Vertical Packaging Machine for 50g Soap Powder is a fully integrated VFFS (Vertical Form-Fill-Seal) system designed for high-speed, precision packaging of detergent powders, cosmetics, and granular chemicals.     Engineered with German Siemens PLC controls and Japanese servo motors, it achieves ±0.1g weighing accuracy at speeds up to 60 bags/minute while maintaining ISO 9001 and CE compliance.

Technical Specifications

Core Components

• Machine Frame: SUS304 stainless steel construction with IP65-rated electrical enclosures for washdown environments

• Feeding System: Twin-screw volumetric filler with anti-segregation baffles (adjustable for 20-100g ranges)

• Film Handling: Pre-printed roll film unwinding with tension control (PET/PE/AL laminates, 70-120μm thickness)

• Sealing Mechanism: Dual heat bars (150-220°C adjustable) + cooling plates for wrinkle-free seals

Performance Metrics

• Throughput: 50-60 bags/minute (50g nominal weight)

• Power: 220V/380V 50Hz, 2.2kW with energy recovery system

• Air Consumption: 0.6MPa, 0.5m³/min for pneumatic actuators

• Noise Level: ≤70dB in operation

Optional Modules

• Nitrogen Flushing: Reduces oxygen content to<2% for oxidation-sensitive powders

• Date Coder: Thermal inkjet printer with 300dpi resolution (batch/expiry dates)

• Metal Detector: Integrated rejection system (Fe: Φ0.8mm, Non-Fe: Φ1.2mm sensitivity)

Application Scenarios

Detergent Industry:

Packaging soap powders with high dust generation (integrated vacuum suction removes 99.8% airborne particles)

Compatible with both synthetic and natural detergent formulations

Food & Cosmetics:

Food-grade models available for baking soda or bath salts (meets FDA 21 CFR 177.1520)

Handles abrasive materials like pumice powder without screw wear

Agricultural Chemicals:

Moisture-proof design for pesticide powders (optional desiccant cartridge maintains<30% RH)

Operational Manual

Setup Procedure

• Film Loading:

Mount film roll on servo-driven shaft → Thread through guide rollers → Align with optical eye mark sensor

• Parameter Configuration:

Input bag dimensions (L: 80-200mm, W: 50-120mm) via HMI

Set fill weight (50g ±0.1g) and sealing temperature (180°C for PE films)

• Test Run:

Execute 10 empty cycles to verify film tracking → Conduct 5 product trials to calibrate fill accuracy

Production Cycle

• Film Forming:

Pneumatic forming shoulder creates tubular bag from flat film

• Filling Phase:

Twin screws deliver powder at 300g/sec (fast fill) → Micro-feed completes last 5g (±0.05g variance)

• Sealing & Cutting:

Horizontal seals made by Teflon-coated jaws → Rotary knife trims excess film

• Output:

Belt conveyor transports bags to collection bin (speed sync with machine)

Maintenance Schedule

• Daily: Clean residual powder from hopper;     inspect screw wear

• Weekly: Lubricate chain drives with food-grade grease

• Monthly: Replace air filters;     calibrate load cells

Troubleshooting Guide

Frequent Issues & Solutions

Film Wrinkling During Sealing

Cause: Uneven jaw pressure or temperature fluctuation

Action: Adjust pneumatic cylinder pressure to 0.4MPa;     stabilize power supply

Inconsistent Fill Weight

Cause: Powder bridging in hopper or screw wear

Action: Install hopper vibrator (30W, 50Hz);     replace screws after 500 operating hours

Mark Misalignment

Cause: Dirty optical sensor or film slippage

Action: Clean sensor lens with alcohol;     increase unwind brake torque by 10%

FAQ Section

Q1: Can it handle fragranced powders with oil content?

Yes, the anti-adhesion screw design prevents clumping for powders with up to 5% oil content.

Q2: What’s the film waste percentage?

<3% waste due to servo-controlled film advancement (vs. 8-10% in mechanical systems).

Q3: How to switch bag sizes?

Change forming collar and input new parameters – typical changeover takes<15 minutes.

Q4: Is remote monitoring supported?

Yes, via Ethernet/IP for OEE tracking and predictive maintenance alerts.
