Application of Air Spring Bellows in Paper Manufacturing​

(1) Felt Deviation Control
During the operation of a paper machine's press felt, pneumatic bellows ensure precise actuation force for the deflection correction system. By adjusting the air pressure in real time, the system can respond quickly to felt deflections and maintain a felt deflection correction accuracy within 0.5 mm. This reduces downtime due to felt misalignment and extends its service life.

(2) Fabric Tension Control
In the press felt section of the paper machine, pneumatic bellows ensure stable operation of the forming fabric through precise tension control. Air pressure is adjusted according to machine speed to maintain optimal tension. Compared to mechanical processes, this method improves energy efficiency and response speed.

(3) Calender Pressure Uniformity
The calender with pneumatic bellows allows precise control of roll pressure through independent multi-point adjustment. This ensures uniform pressure distribution across the entire roll surface and eliminates the "balling effect" common in conventional mechanical processes. This improves paper thickness uniformity and increases product grade.

(4) Constant Doctor Pressure
The pneumatic bellows of the doctor unit maintains constant pressure, ensuring stable contact between the doctor blade and the roll surface. This significantly reduces scratches caused by pressure fluctuations, improves paper surface quality, and extends doctor blade replacement intervals.
