The breast roller is the first roller on the paper-making equipment and is the starting point of the forming table. The breast roller is mainly used for driving and dewatering the mesh section. It is not only powerful, but more importantly, it has higher requirements for surface coverage, wears resistance, and does not damage the mesh. Then do you know what applications and characteristics of the accessories of paper-making equipment? Here are some answers.
Here is the content list:
The application of paper-making equipment line drive roller.
The application of guide rollers for paper-making equipment.
The application of paper-making equipment bending roll.
The characteristics of the pressure roller of paper-making equipment.
The screen drive roller of paper-making equipment is mainly used for the transmission and dewatering of the screen segment. It is not only powerful, but more importantly, it has higher requirements for surface coverage. It is wear-resistant without damaging the paper web and prolongs the service life of the forming wire. And reduce production costs. The screen drive roller is used to support the forming screen and is also the dewatering part of the screen table. Wire-driven rollers play a vital role in the papermaking process. As an important part of paper-making equipment, the steel wire drive roller provides the transmission power to drive the forming fabric.
The most used guide rollers in paper-making equipment are mainly used in the wire section, dryer section, and press section. The main function is to transport the forming fabric, drying fabric, and felt. With the increase in the speed of paper-making equipment and the increase in paper webs, this requires a more uniform wall thickness of the guide roller and higher dynamic deflection requirements to meet the needs of high-speed paper-making equipment. The guide roller is used to keep the wire or felt in a generally fixed position during operation. When the wire or felt deflects, it will be adjusted back to its original position, guiding the wire or felt to always take the correct path.
Paper-making equipment bow rolls are called spreading rolls, bow rolls, curved rod extenders, banana rolls, arc rolls, and wrinkle-removing rolls. The bow roller has a rubber surface, a hard chrome surface, and a Teflon coating for non-stick applications. Hard chrome surface arcuate rollers are used for speeds exceeding 300 meters per minute. If the speed is higher, use a larger diameter to reduce the speed of the roll.
The press roll of paper-making equipment is the main part of the press device. There are many types of press rolls, such as vacuum press rolls, trough press rolls, blind press rolls, sizing press rolls, and so on. The press rolls of paper-making equipment are used to quickly dehydrate the press section and increase the physical properties of the paper.
