Separate Hepa Glass Fiber Pleating Machine

Pulan factory’s quality Separate Hepa Glass Fiber Pleating Machine integrates feeding (magnetic powder brake + air expansion shaft), imported cutting, embossing, paper pulling rollers, and material collection into one complete system. By controlling the speed difference between the embossing device and paper pulling rollers, the fold height can be continuously adjusted without changing rollers.
The paper pulling rollers and take-up system are driven by servo/stepper motors, providing stable transmission and high precision. The machine frame adopts aluminum alloy profiles, offering a beautiful appearance, lightweight structure, and durability.
The machine supports product widths up to 650mm and achieves 100–110 folds/min production capacity at 100mm fold height.

What is Separate Hepa Glass Fiber Pleating Machine?

Separate Hepa Glass Fiber Pleating Machine is an automatic pleating equipment designed for forming glass fiber paper used in separator HEPA filters.
The machine consists of six main parts:
Feeding device
Cutting mechanism
Embossing mechanism
Paper pulling roller mechanism
Touch screen control cabinet
Material collection device
The machine works by setting the time difference between the embossing device operation and the paper pulling roller speed. This allows continuous adjustment of embossing spacing, achieving stepless fold height adjustment without replacing rollers.
It is suitable for mass production of glass fiber paper pleating. The finished pleated paper features smooth end surfaces, accurate dimensions, and consistent folding quality.

Main Components

Feeding Device:
Air expansion shaft (inflation tensioning), magnetic powder brake, coupling, positioning bolts
Cutting Mechanism:
Imported cutting knife (adjustable pneumatic pressure)
Embossing Mechanism:
Embossing cylinder (adjustable depth), embossing knife
Paper Pulling Roller Mechanism:
Paper pulling rollers (servo motor driven), roller cylinder (gap adjustment)
Material Collection Device:
Stepper motor drive, collecting platform
Control System:
Touch screen (Chinese and English), PLC, emergency stop switch
Auxiliary Components:
Pneumatic dual unit, solenoid valve, working table lifting mechanism

Working Principle

The embossing device moves up and down at a fixed frequency, while the paper pulling rollers drive the glass fiber paper forward at a preset speed.
The distance that the glass fiber paper moves between two embossing actions determines the fold height.
By adjusting the matching relationship between the paper pulling speed and embossing frequency, the fold height can be continuously adjusted without replacing rollers.

Production Process

1. Loading
Release air from the air expansion shaft, insert the glass fiber paper roll, inflate the shaft to tighten the roll, place it on the material rack, and connect it with the magnetic powder brake.
2. Paper Threading
Pull the paper head through the tension roller and guide it into the cutting mechanism.
3. Cutting
Adjust the cutting knife spacing according to the product width and remove excess edges.
4. Embossing
The cut glass fiber paper enters the embossing mechanism, and the embossing knife presses folding marks onto the paper surface.
5. Paper Pulling
The paper pulling rollers drive the glass fiber paper forward. The matching speed between embossing frequency and paper feeding speed determines the fold height.
6. Material Collection
The embossed glass fiber paper enters the collecting device and is automatically folded and neatly stacked.
7. Output
Remove the finished folded material after collection.

Core Features

1. Stepless Fold Height Adjustment Without Roller Replacement
By setting embossing time and paper pulling roller speed difference through the touch screen, the fold height can be continuously adjusted (≤250mm). No replacement parts are required, reducing production cost and changeover time.
2. Magnetic Powder Brake + Air Expansion Shaft, Protecting Glass Fiber Paper
The feeding system uses a magnetic powder brake for constant tension control and an air expansion shaft for paper roll tightening. The glass fiber paper is less likely to break or fall during feeding.
3. Imported Cutting Knife, Smooth Edge Without Burrs
The cutting knife pressure can be adjusted pneumatically. The cutting edge remains smooth and clean, improving filter appearance quality.
4. Servo/Stepper Drive, High Precision
The paper pulling rollers use servo motor drive, while the collecting system uses stepper motor drive, ensuring stable transmission, accurate positioning, and consistent fold dimensions.
5. Adjustable Embossing Depth, Suitable for Different Paper Materials
The embossing depth can be adjusted by rotating the embossing cylinder connector:
Clockwise rotation: increase embossing depth
Counterclockwise rotation: reduce embossing depth
6. Quick Correction for Paper Feeding Deviation
Uneven clearance between the two paper pulling rollers is the main cause of deviation. The problem can be corrected by adjusting the cylinder connectors on both sides.
7. Aluminum Alloy Profile Frame, Durable and Attractive
The Separate Hepa Glass Fiber Pleating Machine frame adopts industrial aluminum alloy profiles, providing corrosion resistance, lightweight structure, and a modern appearance.
8. Bilingual Touch Screen with Recipe Storage
The system supports setting production quantity, fold height, motor frequency, delay time, and other parameters. Automatic shutdown after reaching preset production quantity is available.

Technical Parameters

Installation Precautions

Install the Separate Hepa Glass Fiber Pleating Machine on a flat, clean, and well-ventilated floor, avoiding high-temperature dust environments.
Keep ≥1 meter distance from walls at the front, rear, and right side; ≥1.5 meters on the left side.
Use a forklift above 1 ton for transportation.
Fix the machine and calibrate the level.
Power supply: 220V/50Hz with independent grounding.
Air supply pressure: 0.6MPa.
Check cables, emergency stop buttons, and protective covers before operation.

Frequently Asked Questions

Q1: How to adjust when fold height is inaccurate?
A: Fold height is determined by the matching relationship between embossing time and paper pulling roller speed. Adjust the “fold height setting” value in the touch screen motor parameter interface. Also check whether the embossing cylinder operates smoothly and whether the paper pulling rollers slip.

Q2: What should I do if the embossing depth is not suitable?
A: Rotate the embossing cylinder connector:
Clockwise: increase embossing depth
Counterclockwise: decrease embossing depth
If adjustment does not solve the issue, check whether the embossing knife is worn or whether cylinder air pressure is stable.

Q3: What if the magnetic powder brake does not work and tension is unstable?
A: Possible causes:
① Magnetic powder is exhausted → Add magnetic powder.
② Air expansion shaft and magnetic powder brake are not properly connected → Check whether the coupling positioning bolt is correctly engaged.

Q4: How to quickly correct paper feeding deviation?
A: The cylinder connectors on both ends of the paper pulling rollers can be adjusted independently.
Paper deviation to the left: rotate the left connector clockwise or right connector counterclockwise.
Paper deviation to the right: adjust in the opposite direction.
After adjustment, ensure the clearance between both rollers is even.
