Introduce to Full-Auto Knife Paper Pleating Machine（JR-AUTO55-1050F）

 The Full-auto knife Paper Pleating Machine forPP car Air Filter Production Line is a specialized device used to automatically fold PP filter paper into the pleated structure of a car air filter element. The core technology involves alternating folding with upper and lower folding blades, combined with heating and shaping to ensure uniform fold spacing and stable shape.       

 Core Structure

Automatic Paper Feeder: Stable paper feeding and control of filter paper force.

Slitting and Feeding Unit: Pre-slits to target width, with stepless speed adjustment for paper feeding.

Crease/Glue Applying Mechanism: Creates creases and simultaneously applies PP hot melt glue (fixes crease spacing and prevents springback).

Reciprocating Folding Knife System: Alternating upper and lower folding blades for precise folding.

Heating and Shaping Device: Quickly solidifies creases, ensuring consistent crease height and flat ends.

Counting and Conveying: Automatic counting and conveying of finished products to the next process.

Control System: PLC + Touch Screen, allowing setting of parameters such as crease height, speed, and glue application.

Workflow

Unwinding → Slitting → Crimping → Reciprocating Folding → Heating and Shaping → Counting → Conveying. The entire process is automated, highly efficient, and consistent.

Core Advantages

1. Precise Pleating: Reciprocating folding knife + servo control ensures minimal pleat height/pleat distance error and a smooth end face.
2. High Efficiency and Automation: Automatic cutting, folding, shaping, and counting significantly reduce labor and increase production capacity.
3. Strong Adaptability: Compatible with PP filter paper of different weights, supports special pleating patterns such as M-type/W-type.
4. Stable and Reliable: PLC control + frequency conversion speed regulation ensures stable operation and low scrap rate.

Selection Considerations

Production Capacity Matching: Select folding speed and width based on daily air filter output.

Pleating Requirements: For car air filters, prioritize models with precise pleat height control and PP line hot melt adhesive functionality.

Automation Level: Prioritize models with integrated automatic slitting, online glue application, and shaping functions to reduce labor and increase efficiency.
