The Key Papermaking Equipment - Guide Rollers

In the process of paper production, there are many key equipment and components, among which the paper machine guide roller is one of them. Paper machine guide roller is an important piece of equipment used to control the direction and speed of paper movement, and it plays a vital role in the paper production process. This article will introduce the structure, function and application of paper machine guide roller in paper production in detail.

First, the structure of the guide roller of the paper machine

The guide roller of the paper machine is mainly composed of the roller body, bearings, seals and other parts. The roller body is the main part of the guide roller, which is usually made of steel and has a specially treated surface with high wear and corrosion resistance. The bearing is the core component of the guide roller, which bears the gravity of the roller body and the pressure generated by the movement of the paper to ensure the normal operation of the guide roller. The seal is mainly used to prevent the friction between the paper and the roller body from causing the paper to break, and also plays a dustproof and waterproof role.

Second, the function of the guide roller of the paper machine

Control the direction of paper movement: The guide roller of the paper machine changes the direction of movement of the paper so that the paper moves according to the set path, so as to achieve the production requirements of the paper.
Adjust the movement speed of the paper: The guide roller of the paper machine can effectively control the movement speed of the paper by changing the speed of the roller body to meet the requirements of different paper production.
Stabilize the paper tension: The paper guide roller can adjust the tension of the paper by changing the position of the roller body to ensure the stability of the paper in the production process.
Protect the surface quality of the paper: The seals on the guide rollers of the paper machine can reduce the friction between the paper and the roller body, avoid the damage of the paper caused by friction, and ensure the surface quality of the paper.

3. The application of paper machine guide roller in paper production

Paper machine guide rollers play a very important role in paper production, which directly affects the quality, output and production efficiency of paper. Here are some of the applications of paper machine guide rollers in paper production:

Paper sheet forming: In the paper sheet forming process, the paper machine guide roller controls the movement direction and speed of the paper sheet, so that the paper sheet is formed according to the set shape and size, so as to achieve the accurate forming of the paper sheet.
Paper Sheet Traction: In the paper sheet traction process, the paper machine guide roller pulls the paper from the forming section to the pressing section by changing the direction of movement of the paper sheet, so as to realize the continuous production of the paper sheet.
Paper sheet tension control: In the process of paper sheet traction, the paper machine guide roller adjusts the tension of the paper to ensure the stability of the paper in the production process and improve the quality of the paper.
Paper drying: In the process of paper drying, the guide roller of the paper machine controls the movement speed of the paper sheet, so that the paper is evenly heated in the drying part and improves the drying effect of the paper.
