Sanitary Napkin Stacking & Automatic Boxing System

Model: WFR1500 + WL1520D

Device Working Principle

This system is designed for stacking sanitary napkins and seamlessly connecting with automatic boxing machines to perform E1/E2/F1/F2 box-loading modes.

• Products are conveyed from the production line to the stacking unit via conveyor belt.
• The system automatically completes single-pack stacking and pushes them into the boxing machine.
• Controlled by a full-servo transmission and PLC system, ensuring stable, accurate, and efficient operation.
