Full Servo Automatic Adult Diaper Production Line | Built for Stable Output | welldone machinery

When adult diaper manufacturing moves from pilot production to real market scale, stability becomes more important than peak speed.

Many factories discover this only after installation:

• output fluctuates,

• core weight drifts,

• SAP distribution becomes uneven,

• downtime increases as speed rises.

The WD-CRNK-250-HSV Full Servo Automatic Adult Diaper Production Line is engineered specifically to solve these problems — not for demos, but for long-term, high-volume, stable manufacturing.

Designed for Real Market Production, Not Lab Conditions

This full servo adult diaper production line is built for continuous industrial output, not experimental runs.

• Annual capacity: 40–70 million pieces

• Designed speed: up to 250 pcs/min

• Stable operating speed: 200–220 pcs/min

• Finished product passing rate: ≥97%
  (excluding glue applicator & auto splicing factors)

This performance range is ideal for:

• regional adult diaper brands,

• OEM / ODM manufacturers,

• factories upgrading from mechanical or hybrid lines.

Why Full Servo Matters in Adult Diaper Manufacturing

Adult diapers require:

• thicker fluff cores,

• higher SAP loading,

• more complex elastic and tape structures,

• tighter tolerance on weight consistency.

The full servo architecture allows each critical section to operate independently and precisely:

• forming,

• SAP feeding,

• core distribution,

• cutting and stacking.

This directly results in:

• stable core weight,

• consistent absorption performance,

• reduced material waste,

• smoother long-term operation.

Advanced Fluff & Core Forming System

The WD-CRNK-250-HSV adopts a dual-core forming design optimized for adult products:

Mill & Pulp System

• Horizontal pulp rack, supports 4 jumbo pulp rolls

• Maximum roll diameter: 1400 mm

• Maximum pulp width: 508 mm

• Dual crushers with total capacity ≥1100 kg/hour

• Automatic sensor detection with alarm & stop protection

The entire mill system is enclosed in a sound-proof structure, reducing dust and heat accumulation.

High-Precision Fluff Forming

• Main core forming fan power: 75 kW

• Second core forming fan power: 55 kW

• Cellular grid full-ventilated forming wheel

• Divided fluff zones for layered structure

• Bottom fluff ratio: 5–10%

• SAP fully mixed into middle layer

This structure ensures:

• uniform core density,

• soft hand-feel,

• stable absorption performance even at high speed.

Intelligent SAP Application System (2 Sets)

SAP dosing is fully servo-controlled for accuracy and repeatability:

• Distribution range: 3–15 g per piece

• Double-screw fixed-quantity feeding

• Continuous and even SAP distribution

• Touch-screen adjustable SAP percentage

• Automatic suction, level detection & alarm

• Integrated storage tank system

This is critical for adult diapers where absorption reliability directly defines product quality.

Electrical, Utility & Installation Specifications

• Power supply: 3-phase, 5-wire, 380V / 50Hz

• Installed power: 400 kW

• Operating power: ~350 kW

• Compressed air: 0.6–0.8 MPa

• Air consumption: 5000 NL/min

Line Size & Space Requirement

• Machine size: 25.0 × 3.5 × 2.2 m

• Working space: 40 × 12 × 5 m

• Total weight: ~70 tons

• Humidity: 55% RH ±5

• Noise level: ≤87 dB (measured at 1 m)

Designed for long-term operation in standard industrial environments.

Built for Factories That Plan to Scale

The WD-CRNK-250-HSV Full Servo Automatic Adult Diaper Production Line is not about chasing extreme speed numbers.

It is about:

• predictable output,

• controllable quality,

• scalable production,

• and stable long-term ROI.

If you are planning or upgrading an adult diaper factory and need a full servo solution engineered for real manufacturing, this line is built for that purpose.
