Fully-automatic Paper Folding Machine

The Fully-automatic Paper Folding Machine provided by Jundingda supplier combines an automatic unwinding unit and a knife pleating unit on a single production line. It pleats filter paper into M-type, W-type and N-type configurations at 0–300 pleats per minute, with pleat height adjustable from 5mm to 70mm and working width up to 750mm. Pleat distance and pleat height are set through the computer, and the alternating upper and lower knife method completes the folding without damaging the filter paper material.

The machine is built for filter element manufacturers who need to convert raw filter paper into pleated media at a controlled, repeatable pleat height. Cutting size is adjusted through inverter stepless speed regulation and a pneumatic cutting knife, with an infrared monitoring system controlling the cutting process. Pre-heating shaping is completed on the folding machine, so the pleated media leaves the line in its final formed shape.

Machine Specifications

Machine Features

1、The Fully-automatic Paper Folding Machine can precisely adjust the cutting size according to different filter element specifications through the frequency converter stepless speed regulation and a pneumatic cutting knife. It is easy to operate, with smooth cutting effect, and controlled by an infrared monitoring system.

2、The folding machine can fold filter paper with different fold heights (M type, W type, T type, etc.), and the folding distance can be arbitrarily set by the computer.

3、The folding machine uses an alternating upper and lower knife method to complete the folding work. The folding distance is automatically adjusted by the computer to meet various requirements for different fold heights, with accurate size and smoothness.

4、The filter paper completes automatic dot counting, folding processing, and preheating shaping on the folding machine.

5、The folding knife angle of this machine can be changed arbitrarily to ensure that no filter paper material is damaged during folding.

Pleating Type

Product Advantages

Pleat Height Set Through the Computer, Not Mechanical Changeover

Pleat distance and pleat height are set through the computer, and the folding distance is automatically adjusted to match different pleat heights. Changing from one filter element specification to another does not require mechanical changeover of the folding mechanism.

Alternating Upper and Lower Knife Method

The Fully-automatic Paper Folding Machine uses an alternating upper and lower knife method to complete the folding work, with accurate size and smoothness across the pleated media. The folding knife angle can be changed arbitrarily, which prevents damage to any filter paper material during folding.

Infrared-Controlled Pneumatic Cutting

Cutting size is adjusted through inverter stepless speed regulation combined with a pneumatic cutting knife. The cutting process is controlled by an infrared monitoring system, and the cutting effect is flat across different filter element specifications.

Pre-Heating Shaping on the Folding Machine

Pre-heating shaping is completed on the folding machine with a 6kW pre-heating power and a temperature range of 0–250°C. The pleated media leaves the line in its final formed shape rather than requiring a separate shaping step.

Automatic Dot Counting and Folding Processing

Filter paper completes automatic dot counting, folding processing and pre-heating shaping on the folding machine, so the pleat count is controlled by the machine rather than counted manually.

FAQ

What filter paper types can this machine pleat?

The machine folds filter paper with different pleat heights into M-type, W-type and N-type configurations. Pleat height ranges from 5mm to 70mm and is adjustable according to customer requirements. Working width is up to 750mm.

What is the production speed?

Production speed ranges from 0 to 300 pleats per minute. The actual speed depends on the filter paper material, pleat height and working width of the specific filter element being produced.

How is the pleat height changed between different filter specifications?

Pleat distance and pleat height are set through the computer, and the folding distance is automatically adjusted by the computer to match different pleat heights. No mechanical changeover of the folding mechanism is required.

Does the machine damage the filter paper during folding?

The folding knife angle can be changed arbitrarily, which prevents damage to any filter paper material during folding. The folding machine uses an alternating upper and lower knife method to complete the folding work with accurate size and smoothness.
