A paper machine device for anti-deformation press rolls using suction and pulp removal

Abstract

The invention discloses a pulp moisture absorption removal type overturning and anti-deformation pressing roll papermaking machine device. The structure comprises a controller, a driving cavity, a shaft fixing box, a worktable, a supporting framework, a pulp anti-deformation device and a rear separation plate. A wiping sleeve is in contact with an outer surface of a lower pressing roll to wipe andabsorb water, so that the adhesion degree of the surface of the lower pressing roll is reduced; wet pulp paper is not stuck to the outer side and the adhered wet pulp paper also can be cleaned, so that the paper quality of paper sheets is prevented from being influenced and the vibration absorption of equipment is reduced; a wet paper conveyor belt drives a guide wheel and traction steel to moveso that a squeezing pulley moves back and forth and water absorption cotton is squeezed to release water, so that the water absorption performance is kept; when the pressing roll needs to rotate to turn over, the position of a tensioning wheel is changed, and a connection engagement belt is tightly connected with an upper engagement wheel and a lower engagement wheel; and then the lower pressing roll is rotated singly, and the connection engagement belt drives an upper pressing roll to commonly rotate for 180 degrees to turn over the upper pressing roll, so that a condition that the pressing roll is concave and deformed under the action of gravity after the pressing roll is stored for long time so that the wet paper pulp is not uniformly squeezed is prevented.

Description

technical field [0001] The invention relates to the field of paper machines, more precisely, it relates to a paper machine device for wet-turning and anti-deformation press rolls using suction and pulp removal. Background technique [0002] The paper machine mainly includes the processes of beating, sieving, dehydration, pressing, drying and calendering. At present, the pressing and dehydration of wet pulp is through the cooperation of multiple sets of press rolls, so that the wet pulp gradually passes through the gap between the press rolls, so as to achieve paper quality. The paper quality is tight, and the existing traditional technology is not comprehensive, which has the following disadvantages: [0003] The first group of press rolls close to the couch rolls, because the wet pulp conveyed has only been dehydrated in the wire part, and its humidity is relatively high, resulting in too much residual water stains on the surface of the press rolls, which increases its surf...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a paper machine device that utilizes suction and removal of pulp to wet turn over and prevent deformation of the press rolls, so as to solve the problem of the first group of press rolls near the couch rolls in the prior art due to the wet pulp conveyed. Only the dehydration of the wire part is carried out, and its humidity is high, resulting in too much residual water stains on the surface of the press roll, which increases its surface viscosity, making the wet pulp easy to adhere to the outer surface of the press roll, resulting in pits on the surface of the produced paper , the thickness is not uniform, and at the same time the center of gravity of the press roll will shift, causing the equipment to vibrate and aggravate the wear of the equipment, and when the press equipment is not used for a long time, due to the action of gravity, the depression in the middle of the press roll will be deformed, affecting the humidity Disadvantages of press dewatering of pulp
