Small paper machine gear drive

TIME:2019-05-27 BROWSE:2425

  The small paper machine gear transmission is composed of a gear transmission or a plurality of drying cylinders driven by the felt cloth, and a plurality of drying cylinders constitute a drying portion. The linear speeds of the drying cylinders of each group can be adjusted separately to maintain a small differential speed between the drying cylinders of each group to compensate for the shrinkage of the sheet during the drying process. The dryness of the sheet in the dryer section is generally about 92 to 94%. At the end of the dryer section, a cold cylinder is generally provided to allow moisture to condense on the surface of the cylinder. Condensed water wets the surface of the sheet to provide better surface smoothness in the finish. The diameter of the dryer is 1.5m. Single-sided glossy paper can obtain high single-sided gloss by using a large-diameter drying cylinder with high hardness and high-lubricity cylinder surface. The diameter of large-diameter drying cylinder is generally 3 to 7.5 m.
