Bamboo Paper Machine For Tissue Paper Manufacturing

BAMBOO PAPER MACHINE FOR TISSUE PAPER MANUFACTURING 

Bamboo paper machine for manufacturing tissue paper typically consists of several key components and goes through specific processes:

1. Raw Material Preparation System:

- Bamboo Chipping Machine: Bamboo needs to be cut into small chips of appropriate size. This machine is used to chop the bamboo into uniform chips, which is an important preprocessing step to ensure the uniformity of subsequent pulping.

- Washing Equipment: After chipping, the bamboo chips need to be washed to remove impurities such as dust, soil, and other contaminants on the surface of the bamboo, ensuring the purity of the raw materials for pulping.

2. Pulping System:

- Digester: This is a crucial device for converting bamboo chips into pulp. The digester uses chemicals (such as sodium hydroxide, etc.) and high-temperature and high-pressure conditions to break down the lignin, hemicellulose, and other components in the bamboo, separating the cellulose fibers to form bamboo pulp. There are different types of digesters, such as batch digesters and continuous digesters, depending on the production scale and process requirements.

- Refining Equipment: After pulping, the obtained bamboo pulp needs to be refined to further separate and fibrillate the cellulose fibers, improving the quality and uniformity of the pulp. Refining equipment usually includes disc refiners, conical refiners, or other types of refiners, which can adjust the refining degree according to the needs of tissue paper production to obtain the desired pulp properties.

3. Paper Forming System:

- Headbox: The refined pulp is sent to the headbox, which evenly distributes the pulp slurry onto the forming wire or felt. The headbox plays a key role in ensuring the uniformity of pulp distribution on the forming surface, which is directly related to the quality of the formed paper web.

- Forming Wire or Felt: The pulp slurry on the headbox is transferred to the forming wire or felt. Under the action of vacuum suction or other forming methods, the water in the pulp slurry is gradually removed, and the cellulose fibers are intertwined and bonded to form a wet paper web.

4. Pressing System:

- Press Roll: The wet paper web passes through a series of press rolls. The press rolls apply pressure to the paper web to further remove the remaining water in the paper web, reduce the water content of the paper, and increase the density and strength of the paper.

5. Drying System:

- Drying Cylinder: The pressed paper web enters the drying section, which usually consists of a series of heated drying cylinders. The heat from the drying cylinders evaporates the remaining moisture in the paper web, making the paper web completely dry and achieving the required dryness and strength for tissue paper.

6. Finishing System:

- Creping Machine: For tissue paper, the creping process is essential to give the paper softness and flexibility. The dried paper web passes through a creping machine, where a blade scrapes the paper against a rotating cylinder, causing the paper to crinkle and form a certain degree of looseness and softness.

- Cutting and Winding Machine: After creping, the tissue paper is cut into the desired sizes and then wound into rolls or folded into specific shapes according to the product requirements for packaging and sale.
