Joint equipment for paper copying. Mainly composed of parts such as mesh, pressing, and drying. There are two types of mesh: circular mesh and long mesh. The press section is composed of a press roller and paper wool. The drying section consists of one or several drying cylinders. Some long web machines are also equipped with mechanical calenders to improve the smoothness and tightness of the paper. There are many types of paper machines, such as the single drying cylinder paper machine (also known as the Yankee paper machine) for making single sided glossy paper, the long mesh multi drying cylinder paper machine for making general paper, the thin sheet paper machine for making typing paper and cigarette paper, and the cardboard machine for making cardboard.
1. Basic data expressing the production capacity and adaptability of paper machines
The main technical features that express the production capacity and adaptability of paper machines include net paper width, high working speed, adjustment range, forming section, pressing section, and drying section.
2. Basic data expressing the performance and structure of various parts of a paper machine
In order to improve the standardization, serialization, and generalization of paper machine design and manufacturing, it is also necessary to include the main structural data of each part of the paper machine in the design parameters of the paper machine. These structural data include the size and surface layer technical characteristics of various rollers, the size and quantity of panels, the size and quantity of drying cylinders, and the gauge and bearing distance of each part.
3. Data representing the overview of paper machines
Data showing the general situation of small paper machines, such as the length of the whole machine, the total mass, the height from the rail surface, the height of the bottom floor, the total installed power of the transmission system, etc., show the technical and economic indicators of the paper machine, such as the floor area, the space volume, the unit production capacity, the body mass, and the power consumption, which can not be ignored.
