Sizing machine overall design
Abstract：The graduation design topic for sizing machine overall design. Sizing machine is an integral part of the paper making process, its main role is in the pulp coagulated paper surface is coated with a layer of glue, making paper or paperboard surface forms a protection layer, thereby having a resist solution diffusion and penetration ability.
Then the design process, mainly on the sizing machine power and various parts of the strength calculation and checking. The difficulty in the design with an emphasis on roller design. As a result of direct contact with the paper roll, the stiffness, roundness, cylindricity, axis straightness, parallelism and two rollers, two roller surface speed difference has certain requirements, relates to the deflection roller, stiffness, high volume and the number of roller in some matching problems.
Key words： Column type structure；Surface sizing；high volume
