Fourdrinier paper machine consists of the wet part (including the headbox, formator, and pressing and the dry part (drying, calendering, and coiling). According to the number of shapers and drying cylinders, they can be divided into single long mesh, double long mesh, long mesh, multi cylinder, Yankee type and other models; According to the vehicle speed, it can be divided into low-speed and high-speed.

2.1 The headbox is a key component of modern paper machines. Its structure and performance play a decisive role in the formation of paper pages and the quality of paper
Can effectively disperse fibers. A high turbulence headbox can generate high intensity micro turbulence, effectively dispersing fibers, preventing fiber precipitation and re flocculation, and effectively improving the strength of the paper.
Distribute the paper material evenly horizontally along the paper machine. (Determine the lateral quantitative distribution of the paper web)
The spraying is stable, ensuring that the spraying speed is coordinated with the wire speed. (Determine the longitudinal quantitative distribution of the paper web)
Divided into:
Open Headbox
Air cushion headbox
Hydraulic headbox
2.2. Paper drying cylinder refers to the machinery used in paper making machinery to continuously dry the formed paper pulp. Dozens of drying cylinders are placed crosswise in a paper machine. A paper drying cylinder is a drum type pressure vessel with rotating shafts installed on the heads at both ends, and steam for drying paper is introduced through the hollow shaft hole at one end. There is also a lifting bucket inside the cylinder that contains water to send condensed water to the hollow shaft at the other end for discharge. The drying cylinder is generally made by casting cast iron and polishing the outer surface. By utilizing the characteristics of graphite flakes in cast iron, it is easy to detach the paper blank from the cylinder surface and prevent the paper from being stuck during paper drying
