Fourdrinier shaking and vibrating device of fourdrinier papermaking machine

Abstract

The invention relates to a fourdrinier shaking and vibrating device of a fourdrinier papermaking machine. The fourdrinier shaking and vibrating device comprises a shaking and vibrating speed reducer, a vertical beam, a breast roll and a breast roll bearing seat; the fourdrinier shaking and vibrating device is characterized in that an output shaft of a shaking and vibrating speed reduction box is directly connected with the breast roll bearing seat; a breast roll supporting seat is suspended on a stand column through a movable pin connection plate; a forming plate is mounted on the vertical beam; and a drawing rod is mounted on the bearing seat and connected to a drawing supporting seat. Through the fourdrinier shaking and vibrating device of the fourdrinier papermaking machine, original built-in elastic steel sheet connection is transformed into external movable pin plate connection, and a vertically-drawn and integrated steel bar is transformed into a chain type movable pin pull bar, so that the aim of removing fatigue break caused during bending forward and backward; the equipment failure rate is effectively reduced, the paper sheet forming is improved and the efficiency of a machine is improved.

Description

technical field [0001] The invention belongs to the technical field of papermaking machinery, in particular to a vibrating device for a wire part of a fourdrinier papermaking machine. Background technique [0002] Production practice shows that when the speed of the paper machine is lower than 300m / min, if the shaking device is not used, it is generally impossible to obtain a uniform paper web. When the mesh table is shaking: the slurry layer deposited on the mesh surface vibrates with the mesh, and produces a shearing action with the slurry on the relatively stable slurry layer, which can flatten the protruding points on the slurry layer and fill in the low-lying areas in the slurry layer The place. At the same time, the longitudinal arrangement of fibers in the paper web is reduced, so that the arrangement direction of the fibers has a certain angle with the running direction of the forming net. In addition, the directional shearing of shaking can attenuate into the mic...

Problems solved by technology

[0004]However, in the prior art, since the supporting and tensile elastic steel sheets used in the shaking device are all integrated, frequent fatigue fractures occur under the action of reciprocating bending. Equipment failure, thus affecting the stability of product quality and machine efficiency
