Innovation in the manufacturing technology of automatic servo folding machine for pleating filter paper

From Cutting Safety to Intelligent Folding: CH Machinery Equipment Reshapes Air Filter Production with Innovative Patents

In a filter manufacturing factory in Bengbu, Anhui Province, a 7.5-meter automated production line operates silently. Rolled filter paper undergoes steam humidification, precise creasing, high-temperature shaping, and other processes, folded into uniform wave patterns—these pleats will capture dust and impurities in air filters.
The precision of Drum folding machine determines filter efficiency,” the workshop director explains, pointing to operating equipment. “The new generation solves multiple pain points in traditional pleating processes.”

01. Filter paper pleating machine: Dual Breakthroughs in Safety and Efficiency
A front roller-track type pleating machine is currently applying for utility model patent authorization. The equipment innovatively features a height-adjustable top plate system controlled by telescopic rods inside the cutting chamber.
When filter paper enters the cutting position, the rods lift the plate to raise the paper before blades complete the cut—eliminating manual intervention. This innovation addresses safety hazards in traditional Filter paper pleating machines where workers previously placed filter cores during cutting.

02. Comprehensive Automation and Intelligence Upgrade
In CH Machinery Equipment’s workshop, a square air filter production line showcases the high automation level of modern Air Filter Paper Pleating Machines.
The line integrates seven modules (unwinding rack, heater, steam device, pleater, hot melt glue machine) with adjustable speed (5–25 m/min). Its core technology lies in completing creasing and embossing functions on a single pair of high-precision rollers while using steam to protect paper integrity during folding.
CH Machinery Equipment’s production line represents even higher automation. Its fully automatic Air Filter Paper Pleating Machine employs servo control to ensure perfect pleat flatness, with adjustable fold heights (15–100mm).
Automatic servo folding machine represents the industry’s future,” an equipment engineer notes. “Pulan Equipment’s gluing system alone offers six modes—continuous, intermittent, double-sided, single-sided—selectable via computer.”

03. Revolutionary Core Design Innovations
In filter paper pleating technology, bubble pattern design is a game-changing innovation. CH Machinery Equipment’s fully automatic Drum folding machine incorporates this pattern on its drum.
“Large air filters handle high airflow—without bubbles, paper layers compress, increasing resistance,” the technical lead explains. “Bubble patterns ensure uniform folding, maintaining airflow and dust capacity.” The Drum folding machine also uses variable-frequency stepless speed regulation to adapt pleating speed to different materials.
In April 2024, CH Machinery Equipment’s “Continuous Air Filter Paper Folding Machine” incorporated sliding rails on its base. Adjusting the distance between fixed and sliding boxes accommodates varying sizes.
As paper enters the box, partition plates automatically segment it, forming precise creases upon collision. This design “simplifies operations, saving significant labor and costs.”
Slanted pleat depth control was an industry challenge. A 2022 patent solved this with an innovative depth-adjusting mechanism: a three-stage extension plate design at the bottom of the pleating board, extended via the engagement of latch blocks and slots.
A unique buffer mechanism was also added—spring systems cushion pressure during upward movement of pleating blocks, preventing excessive creasing and ensuring quality.

04. Industry Impact and Future Prospects
These innovations are reshaping the filter equipment manufacturing landscape. Rising demand for high-efficiency filters—driven by stricter environmental standards and air purification needs—positions Automatic servo folding machines as key to industrial upgrades.
Filter paper pleating machines seem simple but directly impact filter efficiency and lifespan,” industry experts emphasize. “The new generation Drum Type Air Filter Origami Machine integrates precision machining with intelligent control, solving traditional limitations in flexibility, safety, and adaptability.”
At a Changchun automotive plant, filters produced by the new Drum Type Air Filter Origami Machine are being installed in electric vehicles. These pleated papers will block kilograms of dust and particles throughout the vehicle’s lifecycle.
Every single pleat is a testament to precision. As an Anhui auto parts engineer states: “Our innovation isn’t just mechanical improvement—it’s a commitment to air quality.” With more enterprises joining this technological wave, the once-unassuming filter pleating machine is becoming a new hallmark of high-end manufacturing.
