Separated Hepa Filter Corrugating Machine for Paper or Aluminum

Pulan factory’s quality Separated Hepa Filter Corrugating Machine For Paper Or Aluminum is specially designed for corrugated aluminum foil (or paper) production in separator type HEPA filters. It integrates automatic edge folding, corrugation embossing, fixed-length cutting, and product collection into one machine. The maximum aluminum foil width is 350mm, roll diameter ≤1000mm, and production efficiency reaches 20 sheets/min (at 500mm length). The six-stage roller edge folding system protects aluminum foil edges from damage; precision corrugating rollers ensure flat and symmetrical corrugation; photoelectric sensor control enables accurate cutting length; automatic collection reduces manual handling.

What is Separated Hepa Filter Corrugating Machine For Paper Or Aluminum?

Separated Hepa Filter Corrugating Machine For Paper Or Aluminum is a fully automatic machine that processes aluminum foil or paper through edge folding, corrugation embossing, fixed-length cutting, and automatic collection. It consists of a material feeding system, edge folding unit, corrugating unit, cutting unit, and product collection unit.
The machine is designed for mass production of corrugated aluminum foil used in separator type HEPA filters. Corrugation height and pitch can be customized according to customer requirements. The cutting surface is smooth and clean without burrs.

Working Principle and Production Process

Working Principle

The aluminum foil passes through six-stage rollers for gradual edge folding, then enters the upper and lower corrugating rollers to form uniform corrugation. The photoelectric sensor detects the feeding length and automatically activates the cutting blade. Finally, the collection system automatically arranges and collects finished corrugated sheets.

Production Process:

Material Loading:
Install the aluminum foil roll onto the feeding shaft and fix it with cone holders.
Material Feeding:
Pass the aluminum foil through tension rollers and adjust positioning rings according to material width to prevent deviation.
Edge Folding:
The aluminum foil passes through six-stage rollers. Replace the folding template according to the required edge width and adjust the rollers to form the edge.
Corrugation Forming:
The folded aluminum foil enters the corrugating rollers. Adjust the roller gap to create the required corrugation height and pitch.
Cutting:
The photoelectric sensor detects the preset length and activates the cutting mechanism automatically.
Collection:
Finished corrugated sheets are automatically pushed and stacked by the collection system.

Key Features

1. Automatic Edge Folding Protects Aluminum Foil Edges
The six-stage roller system gradually forms the edge, combined with replaceable folding templates, ensuring the aluminum foil edge remains stable and less likely to be damaged during filter assembly.
2. Flat and Symmetrical Corrugation Forming
Precision upper and lower corrugating rollers create uniform and symmetrical corrugation. The formed corrugation has good stability and is not easy to deform.
3. Photoelectric Cutting Control for Accurate Length
The photoelectric sensor detects the aluminum foil feeding length and automatically triggers cutting when reaching the preset value. The cutting surface is smooth and burr-free.
4. Automatic Product Collection
Finished corrugated sheets are automatically pushed and stacked by the collection system, reducing labor requirements and improving production efficiency.
5. Customized Corrugation Specifications
Corrugating rollers can be customized according to customer requirements for corrugation height and pitch, meeting different separator requirements of HEPA filters.
6. Stepless Speed Adjustment
The motor speed controller allows flexible adjustment of production speed, suitable for different materials and thicknesses including aluminum foil and paper.
7. Quick Replacement of Edge Folding Templates
The folding template can be replaced quickly by loosening fixing bolts, making adjustment convenient for different edge widths.
8. Adjustable Cutting Blade Gap and Easy Maintenance
The upper and lower cutting blade gap can be precisely adjusted through adjustment bolts, allowing quick correction when cutting quality needs improvement.

Technical Parameters

Connect compressed air supply at 0.6MPa.
Check cables, emergency stop button, and safety cover before operation.

Frequently Asked Questions

Q1: What should I do if the corrugation becomes uneven or ladder-shaped?
A: The main reason is that the teeth of the upper corrugating roller are not aligned with the grooves of the lower roller. Loosen the fixing bolts of the lower roller transmission gear, adjust the upper roller position until the teeth and grooves align correctly, then tighten the bolts.
Q2: Why is the cutting surface uneven or unable to cut through?
A: Possible reasons:
① Cutting blade is worn or damaged → sharpen or replace the blade.
② Gap between upper and lower cutting blades is too large → adjust the lower blade pressure bolt until the gap is suitable and the upper blade moves smoothly.
Q3: What should I do if aluminum foil is damaged during corrugation?
A:
① Increase the gap between upper and lower corrugating rollers properly.
② Use higher-quality aluminum foil material.
Q4: How can I adjust the cutting length?
A: Move the position of the photoelectric sensor up or down. When the sensor detects the aluminum foil edge, it triggers the cutting action. Turn off the power or press the emergency stop before adjustment to prevent accidental blade movement.
