Fully Automatic Servo-Driven Knife-Type Paper Folding Production Line

This production line is ideal for automotive, air purification, water filtration, and industrial filtration industries. It is engineered for high-speed production, consistent glue application, and flexible parameter adjustment to accommodate various filter specifications.

1. Fully automatic servo-driven knife-type folding machine employs full servo and electronic cam control for folding operations.

2.Multiple angles—including upper/lower blade opening/closing angles and paper pressing angles—are freely adjustable, suitable for W-fold, step-up fold, and multi-layer material folding.

Technical Parameters of the Pre-slitting Machine

Key Functions and Features of  the Pre-slitting Machine

• Automatic feeding function
• Powder brake, pneumatic shaft, tension regulator with freely adjustable tension,
• Feeding rollers, conveying rollers, each conveying roller equipped with an adjustable pneumatic cylinder at both ends for free adjustment and convenient operation,
• Six slitting blades, each blade's cutting force automatically adjustable for width,
• The pre-slitting paper feeder is the latest upgraded slitter. It can automatically and precisely adjust slitting dimensions according to different filter cartridge sizes via variable frequency drive non-polar speed control and imported pneumatic knives. Operation is convenient, slitting results are flat, and an infrared monitoring system ensures paper feeding speed matches the folder's speed.

Technical Parameters of the Pleating  Machine

Key Functions and Features of  the Pleating Machine

•  Paper Feed Work Platform: Equipped with limit switches to ensure stable feeding of materials of any size without deviation.
• Punching Counting Device: Punch count can be freely controlled via the display screen.
•  Paper Folding Device: Folding is achieved by two servo-controlled blades each on the upper and lower sections, ensuring fast folding speed and high efficiency.
