What is a Full-auto Composited Materials Pleating Machine?

The Full-auto Composited Materials Pleating Machine is an automated pleating system that forms composite filter media by compressing the material between front and rear pleating blades. The machine consists of a pneumatic loading system, an unwinding rack, a front blade assembly, and a rear blade assembly.
During operation, the rear blade holds one side of the filter media while the front blade descends and pushes the material toward the rear blade. The compression action creates pleats at the preset height. This machine is ideal for mass production of large-pleat composite filter media used in coarse and medium-efficiency filtration applications.

Applications and Main Components

Application:

The machine is specially designed for laminating:

Unwinding Rack: Bearing seats and tension rollers
Front Blade Assembly: Front blade, front blade pushing cylinder, and lifting cylinder
Rear Blade Assembly: Rear blade, lifting cylinder, and guide rods
Control System: Chinese-English touchscreen, emergency stop button, and power switch
Auxiliary Components: Air preparation unit, solenoid valves, and speed controller Main power switch

Working Principle and Production Process

Working Principle

The rear blade presses one side of the composite filter media while the front blade lowers onto the material. The front blade cylinder then drives the front blade toward the rear blade. Under the compression force generated between the two blades, the filter media is pleated to the preset height.

Production Process

Material Loading
Insert the shaft through the filter media roll and secure it with the cone holders.
The loading cylinder drives the swing arm to place the shaft onto the bearing supports.
Material Threading
Pull the leading edge of the filter media upward through the tension rollers and position it beneath the rear blade.
Material Clamping
The rear blade cylinder lowers the rear blade to hold the material.
The front blade lifting cylinder lowers the front blade onto the media.
Pleating
The front blade pushing cylinder moves the front blade toward the rear blade.
The composite material is compressed into the preset pleat height.
Return Cycle
The front blade retracts and lifts.
The rear blade rises to complete one pleating cycle.
Continuous Production
The filter media advances automatically for the next pleating cycle.

Key Features

1. Front-and-Rear Blade Compression Pleating for Large Pleat Heights
The Full-auto Composited Materials Pleating Machine supports pleat heights from 20 mm to 300 mm. The touchscreen automatically adjusts the blade stroke according to the preset pleat height, making it ideal for large-pleat filter media production.
2. Pneumatic Loading System
The pneumatic loading arm automatically places heavy filter media rolls onto the unwinding rack, significantly reducing manual labor.
3. Accurate Pleat Height and Smooth Pleat Ends
Digital pleat height settings allow the system to automatically match cylinder travel, ensuring consistent pleat dimensions and smooth pleat edges.
4. Compact Mechatronic Design
With dimensions of 2030 × 1120 × 1620 mm, the machine features a compact footprint while maintaining a high level of automation.
5. User-Friendly Touchscreen Interface

Technical Parameters

Installation Requirements

Install the Full-auto Composited Materials Pleating Machine on a level, clean, and well-ventilated floor away from excessive dust and heat.
Maintain at least 1 meter clearance on the right side and 1.5 meters on the front, rear, and left sides.
Use a forklift with a minimum lifting capacity of 1 ton for transportation.
Secure the machine and ensure proper leveling.
Connect to a dedicated 220V / 50Hz power supply with proper grounding.
Provide compressed air at 0.6 MPa.
Before operation, inspect cables, emergency stop buttons, and safety guards.

FAQ

Q1: What should I do if the actual pleat height does not match the setting?
A: Verify the pleat height setting on the touchscreen and check whether the front blade cylinder stroke matches the configured value. Manual mode can be used for testing. If deviations remain, adjust the cylinder travel limit or inspect air pressure stability.

Q2: Why is the loading cylinder not operating?
A: Possible causes include:
Damaged solenoid valve
Faulty pneumatic cylinder
Insufficient air pressure
Air supply not connected
Inspect and correct the corresponding issue.

Q3: Why does the filter media drift or produce uneven pleat edges?
A: Ensure the material feeds smoothly between the tension rollers and blade assemblies. Check that the front and rear blade surfaces remain parallel and free from wear. Also verify guide rail alignment and centering devices.

Q4: What materials can this machine process?
A: The Full-auto Composited Materials Pleating Machine is suitable for composite filter media used in coarse and medium-efficiency filters, including:
Nonwoven fabric and wire mesh composites
Nonwoven fabric and activated carbon composites
Other composite filtration materials
It is especially suitable for large pleat height products ranging from 20 mm to 300 mm.
