2700/600 Crescent high-grade tissue paper machine
1.Paper kinds: High-grade tissue paper
2.Basis weight: 14～40g/m2
3.Trim width: 2700mm
4.Working speed: 600m/min
5.Design speed: 650m/min
1.Headbox: The machine adopts full stainless steel hydraulic headbox.The distributing bundle is combined with diffusion tubes.The diffusion tube bundle adopts the diffusion-finally section tube through the precise calculation, horizontal distribution and dispersion to the pulp which is from the inlet pipe so that the pulp has the uniform distribution effect and good dispersion characteristics, which guarantees the quality of paper.
The cloth paste machine adopts the conical pipe pulp feeding, the pulp inlet cone pipe is combined of big straight round pipe, conical pipe and small straight round pipe. The conical pipe has the pressure balance show device. The homogenate is a turbulence generator which is combined of fixed hydraulic components and made of shaped steel tube whose inlet section is circular and outlet section is square. Between the pressure screen and the head box installed the pulse reduction tank, it can reduce the pulsation from flow system significantly so as to improve the paper index.
2.Crescent forming section: Vacuum cylinder can contribute to paper forming instantly. The frame of cantilever wire and felt changing, can effectively shorten replacement time. It adopts pneumatic constant tension stretcher and guarantee tension of forming wire is constant.
3.The press and dryer section: it adopts vacuum roller press technology, effectively reduces the moisture of wet paper before entering into the dryer cylinder. It uses the alloy dryer of 3.6 meter diameter, high temperature hot air cover, and effectively increases the dryer capacity. It is equipped with 2 sets of high pressure crepe doctor blade and a set of clean blade. There is no need to stop machine for changing the blade, so it can save time. Cylinder adopts low noise enclosed gear box drive and circulating oil lubrication
4.Drive section: The complete machine dryer section adopts advanced step drive digital frequency control technology, which guarantees drive accuracy of each parts and operation stability of paper machine
