Description
A cylinder paper machine is a mechanical device widely used in the papermaking industry,primarily for producing various types of paper(e.g.,packaging paper,tissue paper,cardboard).Below is a detailed introduction:
1.Definition&Basic Structure
This type of cylinder paper machine is an improved version of traditional cylinder paper machines.Its core feature is the addition of a vacuum dewatering system to the traditional cylinder section,enhancing paper-forming efficiency and uniformity.The main components include:
●Cylinder Section
◆Wire Cylinder:A rotating drum covered with a metal mesh,where pulp undergoes initial dewatering to form a wet web.
◆Couch Roll:Works with the wire cylinder to squeeze the wet web,aiding dewatering.
◆Vacuum System:Uses negative pressure to remove water from the pulp,accelerating dewatering and improving fiber distribution uniformity.
●Press Section
◆Dryer Cylinder:A steam-heated metal drum that evaporates residual moisture from the paper.
●Drying Section
◆Dryer Cylinder:A steam-heated metal drum that evaporates residual moisture from the paper
◆Dryer Fabric:Supports the paper through the dryer cylinders to prevent shrinkage and deformation.
●Winder
◆Winds the dried paper into large rolls for subsequent cutting and processing.
2.Working Principle
●Pulp Formation:Diluted pulp flows into the vat and evenly coats the rotating cylinder surface.
●Vacuum Dewatering:The vacuum system creates negative pressure inside the wire cylinder,rapidly extracting water and forming a wet fiber layer on the mesh surface.
●Pressing&Shaping:The wet web is compressed by press rolls to reduce moisture content and enhance fiber bonding.
●Drying Process:The wet paper passes through steam-heated dryer cylinders to evaporate residual moisture,forming the final product.
●Winding&Packaging:The dried paper is wound into large rolls by the winder for packaging.
3.Core Advantages
●High Dewatering Efficiency:The vacuum system significantly accelerates dewatering,ideal for producing high-grammage or thick paper.
●Compact Structure:Requires less floor space,with lower investment and maintenance costs compared to Fourdrinier paper machines.
●Versatile Adaptability:Capable of producing diverse paper types(e.g.,corrugated paper,tissue paper,specialty board).
●Energy Efficiency:Lower energy consumption compared to high-speed paper machines,making it suitable for small to medium-sized mills.
4.Application Areas
●Packaging Materials:e.g.,corrugated paper for cartons,kraft paper.
●Tissue&Household Paper:Toilet paper,napkins.
●Industrial Paper:Specialty papers like insulation paper,filter paper.
●Cultural Paper:Lightweight printing paper,handmade paper(requires process adjustments).
