As global demand for disposable underpads and pet training pads continues to grow, manufacturers are facing higher requirements for production speed, product consistency, and long-term equipment stability.

Welldone Machinery introduces the Full Servo Underpad & Pet Training Pad Production Line (WD-CD250 Series) — an upgraded solution based on our proven WD-CD200 platform, engineered to support large-scale, high-efficiency, and low-defect manufacturing.

This production line is designed for factories aiming to build a sustainable, automated, and competitive hygiene product business.

Why Full Servo Technology Matters in Underpad & Pet Pad Manufacturing

Traditional mechanical or semi-servo machines often struggle with:

Unstable absorbent core weight
Material misalignment at high speed
Frequent downtime for adjustments
Limited upgrade capability
High defect rates during continuous operation

Welldone’s full servo, shaft-less architecture solves these problems by introducing:

Independent servo control for key stations
Modular functional design
Intelligent tension management
Real-time monitoring & auto correction
Higher precision in cutting, forming, and stacking

The result: higher output, lower waste, and predictable product quality.

Core Advantages of Welldone Full Servo Production Line

1. Full Servo Modular Design (Shaft-less Transmission)

Independent servo motors for forming, feeding, cutting, folding, and stacking
Modular structure for easier maintenance and future expansion
Faster installation and simplified troubleshooting
Long-term adaptability to new product specifications

This structure allows factories to upgrade capacity or product types without replacing the entire production line.

2. Intelligent Industrial Control System

Professional industrial computer interface
PLC + touchscreen operation
Real-time data collection
Automatic fault alarm & safety monitoring
Parameter memory for different product sizes

Operators can control the entire line with minimal training while maintaining consistent quality standards.

3. High-Precision Raw Material Handling System

Servo-controlled auto unwinding with buffer tension balance
Zero-time splicing system
One-touch direction switching
Automatic web guiding (rectifier system)

This ensures:

No material deviation at high speed
Stable layer alignment
Reduced waste
Improved final product appearance

4. Advanced Absorbent Core Forming Technology

The absorbent core is the heart of every underpad or pet training pad.

Welldone integrates:

Hammer mill fiber defibration system
Multi-zone fluff forming box
Servo-controlled fluff feeding
Uniform SAP mixing
Optional auto humidifier system (anti-static & dust reduction)

Benefits:

Accurate weight control for every pad
Uniform absorption performance
No pulp clogging
Stable performance even at high speed

5. Integrated Vacuum Conveyor & Auto Defect Rejection

Full vacuum conveying system ensures stable product transfer
Adjustable belt positions
One-side unloading design for fast size change
Automatic defective product rejection

This significantly reduces manual intervention and improves overall production efficiency.

6. Heavy-Duty Mechanical Structure for Long-Term Operation

CNC-machined main components
30mm steel wall-type frame structure
Reinforced transmission base plates
Enlarged rear gearbox for easier maintenance
Square steel tube base structure (150×150×8mm)

Designed for 24/7 industrial operation in high-load environments.

7. CE Standard Safety & Global Components

CE compliant design
CE certified electrical parts
Safety doors
Emergency stop system
Temperature auto-control for heating elements

Key purchased components from internationally recognized brands ensure reliability and long service life.
