2) well-distributed pulp device
The well-distributed pulp device is two doctor rollers (lip doctor roller and throat doctor roller), with double spiral holes and quality stainless steel pipe (304).
The parameters such as the diameter of the doctor roller and the opening rate are determined according to the process requirements.
3) lip device
The lip device is composed of upper and lower lip plates, fine-tuning mechanism and lip opening indicator.The upper lip plate is a special joint structure. Can up and down, before and after adjustment lip opening.
Headbox is the key part of modern paper machine. Its structure and performance play a decisive role in the formation of paper pages and the quality of paper.
Classified editor:Open headbox,Air cushion headbox,Hydraulic headbox.
Its main tasks:
It can disperse fiber effectively. High turbulence headbox can produce high-intensity micro turbulence, effectively disperse fibers, prevent fiber precipitation and re flocculation, and effectively improve the strength of paper.
Evenly distribute the paper material horizontally along the paper machine. (determines the horizontal quantitative distribution of the web)
The shotcreting is stable to ensure the consistency between the slurry speed and the mesh speed. (determines the vertical quantitative distribution of the web)
