What is the function of Paper Machine Vacuum Press Roll
2026-03-11
The vacuum press roller is a key component of the paper machine press section, with the core function of efficient dewatering, improving paper forming, and enhancing paper quality, mainly reflected in the following aspects:
1.Strong vacuum dehydration
By using internal vacuum suction, the moisture in the wet paper is quickly and evenly removed, greatly improving the dryness of the pressing section and reducing the load on the subsequent drying section, saving energy and reducing consumption.
2.Ensure that the paper is uniform and flat
Vacuum can firmly adhere the paper sheet to the roller surface or blanket, preventing wrinkling, folding, and deviation of the paper sheet, making the moisture and thickness of the entire paper more uniform, and improving the flatness of the paper.
3.Improve paper strength and surface properties
Under the combined action of pressure and vacuum, the fibers bond more tightly, improving the tightness, tensile strength, and surface smoothness of the paper, and reducing shedding of hair and powder.
4.Stable operation, increase vehicle speed
Vacuum adsorption enables stable transfer of paper sheets at high speeds, reducing paper breakage and making it suitable for continuous production on medium to high speed paper machines.
5.Protect the woolen fabric and extend its service life
Assist in dehydrating and maintaining breathability of woolen fabrics, reduce clogging of woolen fabrics, and ensure more stable operation and longer lifespan of woolen fabrics.
