Integrated equipment for papermaking. It mainly consists of a net, a press, and a drying section. The net section includes both round and long nets. The press section consists of press rolls and paper felts. The drying section consists of one or more drying cylinders. Some long-net 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 single-cylinder paper machines (also known as Yankee paper machines) for manufacturing single-sided coated paper, long-net multi-cylinder paper machines for manufacturing general paper, thin paper machines for manufacturing typing paper and cigarette paper, and paperboard machines for manufacturing paperboard.
1. Basic data expressing the production capacity and adaptability of the paper machine
The data expressing the production capacity and adaptability of the paper machine include the net paper width, maximum operating speed, adjustment range, and the main technical characteristics of the forming section, pressing section, and drying section.
2. Basic data expressing the performance and structure of each part of the paper machine
In order to improve the standardization, serialization, and generalization of paper machine design and manufacturing, the main structural data of each part of the paper machine should also be included 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 number of drying cylinders, the track gauge, and bearing distance of each part, etc.
3. Data representing the general overview of the paper machine
Data representing the general overview of small paper machines, such as the overall length, total weight, maximum height from the rail surface, bottom height, total installed power of the transmission system, etc., show the floor area, space volume, unit production capacity, machine weight, and power consumption, etc., technical and economic indicators, so it is also data that cannot be ignored.
