Filter Paper Knife Pleating Machine

Working Principle

• Cutting and Folding: The filter paper knife pleating machine precisely cuts the filter paper through a cutting tool and then uses a folding mechanism to fold the cut filter paper into a pleated shape according to the set mode and size. This is done to increase the filtration area and efficiency of the filter paper.
• Driving System: Usually, it is driven by an electric motor. Through transmission devices such as gears, chains, or belts, the power is transmitted to each working component, enabling the coordinated operation of the cutting tool and folding mechanism to achieve the continuous cutting and folding of the filter paper.
• Control System: It adopts a programmable logic controller (PLC) or other control systems. Parameters such as cutting length, folding width, pleat height, and folding speed can be accurately set and controlled to ensure the accuracy and stability of the pleating process.

Structural Components

• Feeding Mechanism: Responsible for accurately transporting the filter paper roll or sheet - type filter paper to the cutting and folding stations. It generally includes components such as a unwinding device, tension control system, and guide rollers to ensure that the filter paper maintains appropriate tension and position accuracy during transportation.
• Cutting Mechanism: Consists of a cutting tool, tool holder, driving device, etc. The cutting tool is usually a sharp blade or circular knife, which can quickly and accurately cut the filter paper into the required length and shape.
• Folding Mechanism: It is a key component for folding the filter paper. Usually, it is composed of one or more sets of folding plates, push plates, pressure rollers, etc. Through a sophisticated mechanical design, the cut filter paper is gradually folded into the specified pleat shape.
• Heating Device: Some filter paper knife pleating machines are equipped with a heating device, which is used to heat - set the folded filter paper to make the pleats more firm, improving the stability and filtration performance of the filter paper. The heating method can be electric heating, hot - air heating, etc.
• Counting and Marking Device: Capable of counting the folded filter paper, which is convenient for production statistics and quality control. At the same time, information such as batch number, production date, and specification can be marked on the filter paper for product traceability and management.

Characteristics and Advantages

• High - efficiency Production: It has a high pleating speed, capable of achieving dozens or even hundreds of folding operations per minute, which greatly improves production efficiency and meets the needs of large - scale production.
• High Precision: It can precisely control parameters such as cutting length, folding width, and pleat height, with a small error range. This ensures the consistency and accuracy of filter paper folding, which is beneficial for improving the quality stability of filtration products.
• Strong Flexibility: By adjusting the parameters of the control system, it is convenient to change the folding mode, size, and shape of the filter paper to meet the needs of different filtration products. It has strong versatility and flexibility.
• High Degree of Automation: The processes from feeding, cutting to folding and counting can be automated, reducing manual intervention, reducing labor intensity, and improving the reliability and safety of the production process.

Application Areas

• Air Filter Manufacturing: It is used in the production of air filters for automobiles, motorcycles, construction machinery, air - conditioning equipment, air purifiers, and other fields. By folding the filter paper, the filtration area is increased, and the air filtration effect is improved, effectively removing impurities such as dust, pollen, and particulate matter from the air.
• Liquid Filter Manufacturing: In the production of liquid filtration products such as oil filters, fuel filters, hydraulic oil filters, and water filters, the filter paper knife pleating machine folds the filter paper into a suitable shape and size to filter impurities, metal chips, sediments, etc. in the liquid, protecting the normal operation of equipment such as engines and hydraulic systems.
• Other Fields: It can also be applied to the filtration in the food and beverage industry, the liquid medicine filtration in the pharmaceutical industry, the liquid and gas filtration in the chemical industry, and other fields, providing efficient and reliable filter paper folding solutions for various filtration applications.

Operating Precautions

• Safety Protection: When operating the filter paper knife pleating machine, the operator must strictly follow the safety operation procedures and wear personal protective equipment such as protective gloves and goggles to prevent accidental injuries.
• Equipment Maintenance: Regularly maintain the equipment, including cleaning, lubricating, and tightening each component. Check the wear condition of the cutting tool and replace the severely worn cutting tool and other vulnerable parts in a timely manner to ensure the normal operation of the equipment and the pleating quality.
• Material Selection: According to different filtration requirements and application scenarios, select the appropriate filter paper material. At the same time, pay attention to the quality and performance of the filter paper, and avoid using damp, deteriorated, or defective filter paper to prevent affecting the filtration effect and equipment operation.
