Introduction to Suction Rolls on Paper Machines

In the papermaking process, vacuum rollers are a key component, mainly used to improve the quality and production efficiency of paper. The following are several common types of vacuum rollers and their functions:

1. Suction press roller

-Function: The vacuum press roller is mainly used to apply pressure during the pulp dewatering process, helping to remove excess moisture. Through the action of vacuum, the roller can effectively extract moisture from the pulp, thereby improving the drying efficiency of the paper.

-Characteristics:

-Improve the dryness and strength of paper.

-By adjusting the vacuum degree, the thickness and density of the paper can be controlled.

-Suitable for various types of paper production, such as cultural paper, packaging paper, etc.

2.Suction couch roller

-Function: suction rollers are usually located in the forming section of paper machines and are mainly used for pulp forming and preliminary dewatering. It fixes the pulp on the roller surface through vacuum suction, ensuring that the paper is evenly formed.

-Characteristics:

-Provide a stable paper forming environment to reduce paper deformation and defects.

-By adjusting the vacuum degree, the flow ability and forming effect of pulp can be optimized.

-Helps improve the surface quality and smoothness of paper.

3. Suction transfer roller

-Function: The suction transfer roller is used to transfer wet paper from one process to another, usually when the paper is transferred from the forming section to the drying section. It firmly adheres the paper to the roller surface through vacuum suction, ensuring the stability of the paper during transfer.

-Characteristics:

-Reduce damage and tearing of paper during transfer.

-Improve production efficiency and ensure smooth transition of paper to the next process.

-Suitable for various types of paper, especially performing well in high-speed production lines.

Suction rollers play a crucial role in paper machines, helping to improve the quality and production efficiency of paper through different functions and designs. Whether it is a vacuum press roller, a vacuum press roller, or a vacuum suction roller, they all provide necessary support for the smooth progress of the papermaking process. Choosing the appropriate type of Suction roller can effectively improve the production efficiency and market competitiveness of paper.
