A press device for a paper machine
By adopting a steel ring assembly and pressure roller assembly design in the paper machine pressing device, surface pressure contact is achieved, the pressing area is increased, and the problems of low efficiency of traditional roll-to-roll extrusion and high cost of shoe-type pressure rollers are solved, thereby improving dewatering efficiency and reducing maintenance costs.

Abstract
This invention specifically relates to a pressing device for a paper machine. The invention includes a bottom roll and bearing housing, a gantry beam, an outer pressure roller beam, an outer hydraulic cylinder assembly, two outer pressure roller assemblies, an inner pressure roller beam, two inner hydraulic cylinder assemblies, four inner pressure roller assemblies, and a steel ring assembly. The bearing housing is fixed to the gantry beam. The bottom roll is supported by the bearing housing. The outer hydraulic cylinder assemblies are mounted on the outer pressure roller beam, with the outer pressure roller assemblies correspondingly located at their output ends. The inner hydraulic cylinder assemblies are located on both sides of the inner pressure roller beam, with the inner pressure roller assemblies correspondingly located at their output ends. This invention increases the contact area between the steel ring assembly and the bottom roll in the pressing area, enabling rapid and effective removal of moisture from the paper layer, thus significantly improving pressing efficiency.
