Roller outermost layer all uses the capillary layer that capillary materials is made, it is ensured that the water squeezed out can turn round and look at and quickly be flowed into pore
In, it is not result in adding on the paper that the water pressed out flows to extrude.
(2) due to action of gravity, the upper-lower position of upper roller and lower roll is arranged, and the water major part of squeezing can flow to lower roll naturally
Surface, therefore arranges vacuum equipment, and upper roller arranges air-blast device in lower roll, so at the extruding of two pressure roller, and air-flow
Lower roll can be flow to from upper roller, and drive the water squeezed out to follow air current flow.
(3) by arranging air-flow guide layer, it is ensured that vacuum equipment is primarily directed to extrusion position and bleeds, so
In time the water in the pore of capillary layer quickly can be aspirated away, it is ensured that the water absorbing properties of pore remains at higher
Level.
(4) two ventilating areas are oppositely arranged, and can be picked up by the moisture of paper both sides faster, define squeezing and take out
Inhale dual water removal effect.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings；
Fig. 1 is the structural representation of the preferred embodiments of the present invention；
In figure: 1, upper roller, 2, lower roll, 3, capillary layer, 4, air-flow guide layer, 5, ventilating area, 6, seal area, 7, paper.
Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the signal of simplification
Figure, illustrates the basic structure of the present invention the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As it is shown in figure 1, the capillary air pressure pressure roller group of a kind of paper grade (stock), including: two squeezings mutually pressed together
Roller, and two pressure roller are setting up and down, are respectively upper roller and lower roll, are hollow-core construction at pressure roller axle center, upper roll end is provided with
Positive air pressure device connect its hollow-core construction, the negative pressure device that lower roll end is provided with connects its hollow-core construction, the roller of pressure roller
Wall includes double-layer structure, is respectively the air-flow guide layer with air-vent and is positioned at the capillary layer outside air-flow guide layer, capillary
Layer can circling gas flow guide layer for the relative rotation, the air-vent of air-flow guide layer in upper roller and air-flow guide layer in lower roll saturating
Pore is all concentrated near the tangent position between upper roller and lower roll.
Two pressure roller press together, and paper can be formed extruding force, and squeeze out the water in paper, two squeezings
Roller outermost layer all uses the capillary layer that capillary materials is made, it is ensured that the water squeezed out can turn round and look at and quickly be flowed into pore
In, it is not result in adding on the paper that the water pressed out flows to extrude.Upper bottom due to action of gravity, upper roller and lower roll
Installing, the water major part of squeezing can flow to lower roll surface, therefore arrange vacuum equipment in lower roll, and upper roller arranges air blast naturally
Device, so at the extruding of two pressure roller, air-flow can flow to lower roll from upper roller, and drives the water squeezed out to follow air-flow
Flowing.
Capillary layer has the material with pore to make, and capillary materials is made up of the resin being doped with temperature-sensitive material, then
By adding the resin of hot doping, cause thermo-sensitive material in resin gradually to separate out, resin is deformed into countless pores, therefore sets
Fat has certain air-and water-permeable performance, and can be quickly directed in the resin of capillary material by a small amount of squeeze water.
Resin itself possesses certain pliability, when two pressure roller mutually extrude, and a certain degree of deformation that capillary layer produces, lead
The region causing two pressure roller extruding forms the planar structure of one fixed width, adds somewhat to pressurised zone significant surface
Long-pending, squeezing effect is more preferable.
Being provided with ventilating area and seal area on air-flow guide layer, the intensive air-vent that is provided with on ventilating area, ventilating area is for possessing
One fixed width, and length direction is axially in parallel with pressure roller, the corresponding region that ventilating area is positioned at roller and lower roll presses together.
By arranging air-flow guide layer, it is ensured that vacuum equipment is primarily directed to extrusion position and bleeds, so can in time by
Water in the pore of capillary layer quickly aspirates away, it is ensured that the water absorbing properties of pore remains at higher level.Two
Ventilating area is oppositely arranged, and can be picked up by the moisture of paper both sides faster, defines squeezing and aspirating and dual imitates except water
Really.
Pressure roller both ends of the surface all seal setting, and capillary layer one end connects bearing, and the other end connects driving means, driving means
Capillary layer can be driven to rotate along own axes.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel is the most permissible
In the range of without departing from this invention technological thought, carry out various change and amendment.The technical scope of this invention
The content being not limited in description, it is necessary to determine technical scope according to right.
