How the writing paper machine works
The working principle of the paper machine is mainly realized through the following parts: paper supply, stock distribution, dehydration, pressing, drying, pressing, rolling paper.
- Paper feed part: The paper raw material is cut to the appropriate size and sent through a series of conveyor belts to the next stage.
- Pulp distribution part: The pulp is screened on a rotating screen, and chemicals are added to improve its quality.
- Dehydration stage: Water is removed from the pulp by high pressure and high speed rotation.
- Pressing and drying: the pulp is compressed and further dehydrated.
- Calender: Use high pressure and high temperature to smooth the paper and improve its quality.
- Roll the paper: Roll the paper to the appropriate length and cut it.
The advantages of paper machines lie in their efficiency and flexibility. In addition, paper making machinery includes raw material preparation, pulping, paper making, until the production of rolled or flat finished products, as well as processing paper and board machinery, covering the entire production process from raw materials to finished products.
