Abstract
The invention discloses a pressure roller of a papermaking machine. The pressure roller comprises a roller body and roller shafts which are arranged at the two ends of the roller body and are coaxial with the center of the roller body, wherein a semi-circular-arc bulge which is concentric with the roller body is arranged on the outer surface of the roller body; the semi-circular-arc bulge has a thickness of 20mm-40mm; the semi-circular-arc bulge is connected and provided with a grinding plate; the side edge, connected with the grinding plate, of the semi-circular-arc bugle anticlockwise rotates by 15-30 degrees from a 12 o'clock position; the other side, connected with the grinding plate, of the semi-circular-arc bugle also anticlockwise rotates by 15-30 degrees from the 12 o'clock position; the sum of the length of the semi-circular-arc bulge and the length of the grinding plate is equal to the perimeter of the roller body; the thickness of the grinding plate is the same as that of the semi-circular-arc bulge; a micro gap which is similar with a marble surface isare formed in the grinding plate; the grinding plate is made of a plastic-type material with light mass, high hardness and good elasticity; and the roller body and the semi-circular-arc bulge are designed in a concentric and integrated manner, and the roller body is made of a steel material with relatively high hardness. According to the pressure roller, the anti-adhesion micro gap iss are formed in the grinding plate, so that the extrusion efficiency is quicker.
Description
Technical field
The present invention relates to papermaking press parts, specifically a kind of paper machine pressure roller.
Background technology
The effect of paper machine press section is to make l Water Paper page be dehydrated, and paper machine pressure roller is the important composition of press device of paper-making machine
Parts, are mainly used for extruding the moisture in the paper pulp on woollen blanket；Pressure roller in existing press device of paper-making machine is by roll body
And it is arranged at the roll shaft composition that roll body two ends are coaxial with roll body, the material of its roll body generally uses the material being prone to peel off with paper,
Most use marbles or sheet metal roller；Marble has certain disadvantages and advantage, and its advantage is marble interior tissue
In there is many small spaces, the beneficially stripping of l Water Paper page, but its shortcoming is also apparent from, it is simply that high cost, and
It is very easy to rupture；Metallic roll is relatively good relative to marble, and its intensity is higher, service life length, dewatering efficiency good.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of simple in construction, extruding is more abundant, valency
A kind of paper machine pressure roller that lattice are more cheap, dehydrating effect is good.
The technical scheme is that a kind of paper machine pressure roller, by roll body and be arranged at roll body two ends and roll body center with
The roll shaft composition of axle, it is protruding that described roll body outer surface is provided with semi arch body concentric with roller, and described semi arch projection has
The thickness of 40mm-80mm, described semi arch projection is connected and installed with rolled plate, the limit that described semi arch projection connects with rolled plate
Along all rotating 15 °-30 ° counterclockwise from ten two directions, and semi arch projection as the another side of rolled plate from ten two sides
To rotating 15 °-30 ° counterclockwise.
Further, the length that described semi arch is protruding is added with the length of rolled plate equal to roll body girth.
Further, the thickness that the thickness of described rolled plate is protruding with semi arch is identical.
Further, described rolled plate arranges the microgap similar with marble surface.
Further, described rolled plate is light weight, hardness height, the plastic rubber sectional material matter of good springiness.
Further, described roll body and the design that semi arch projection is concentric consubstantiality, and its material is the steel that hardness is higher
Iron material matter.
The invention have the advantages that: roll body can drive rolled plate, due to rolled plate light weight, hardness when rotating
High, good springiness, the wet pulp on woollen blanket can be pressed in advance by rolled plate than roll body, was ground by roll body and makes wet pulp
Drainage is more abundant, and during roll body rotates, rolled plate has good elasticity, together with the whole meeting of rolled plate is rolled with roll body,
Repeat to roll, and on rolled plate, be provided with the microgap similar with marble surface, it is possible to preferably peel off page；Total comes
Saying, type of the present invention saves money, material-saving, more preferable setting-out effect.
Accompanying drawing explanation
Fig. 1 is that the present invention faces structural representation.
Fig. 2 is side-looking roll body of the present invention and rolled plate whole body structure schematic diagram.
Fig. 3 is side-looking roll body of the present invention and rolled plate deployed configuration schematic diagram.
In figure: 1, roll body 2, roll shaft 3, semi arch projection 4, rolled plate.
Detailed description of the invention
Below in conjunction with embodiment, technical solution of the present invention is further illustrated:
Embodiment 1:
As shown in Figure 1, Figure 2, Figure 3 shows: a kind of paper machine pressure roller, by roll body 1 and be arranged at roll body 1 two ends and roll body 1 central coaxial
Roll shaft 2 form, described roll body 1 outer surface is provided with semi arch projection 3 body concentric with roller, and described semi arch projection 3 has
The thickness of 20mm-40mm, described semi arch projection 3 is connected and installed with rolled plate 4, and described semi arch protruding 3 connects with rolled plate 4
Edge all rotate 15 °-30 ° counterclockwise from ten two directions, and semi arch protruding 3 as the another side of rolled plate 4 from ten
2 directions rotate 15 °-30 ° counterclockwise.
Further, the length of described semi arch projection 3 is added with the length of rolled plate 4 equal to roll body 1 girth.
Further, the thickness of described rolled plate 4 is identical with the thickness of semi arch projection 3.
Further, described rolled plate 4 arranges the microgap similar with marble surface.
Further, described rolled plate 4 is light weight, hardness height, the plastic rubber sectional material matter of good springiness.
Further, described roll body 1 and semi arch protruding 3 is the design of concentric consubstantiality, and its material is that hardness is higher
Iron and steel material quality.
The present invention is in use: makes smooth being positioned over of rolled plate need to extrude on paper pulp, rotates clockwise, rolled plate
In advance paper pulp can be pressed, facilitate roll body finally to roll, can more fully paper pulp moisture be rolled, when needing
Often rolled plate is checked cleaning, so as not on be stained with residue, affect the later stage use.
