Abstract
The utility model relates to the technical field of paper making equipment, and particularly provides a cambered surface roller in a paper making machine. The cross section of the cambered surface roller is circular. The cambered surface roller comprises installing parts at the two ends and a roller body part in the middle. The diameter of the cross sections of the two sides, close to the installing parts, of the roller body part is larger than the diameter of the cross section of the middle section of the roller body part. The installing parts and the roller body part are connected into a whole and formed by cutting stainless steel bars. The cambered surface roller is simple in structure and low in cost, the cambered surface roller can be machined and formed through simple mechanical cutting, the functions of a traditional cambered surface roller can be achieved, and paper is prevented from generating folds.
Description
Technical field
The utility model relates to the paper making equipment technical field, and the roller of the cambered surface in a kind of paper machine specifically is provided.
Background technology
The cambered surface roller used in the prior art paper machine, put a gum cover by arc shaft and form.Such cambered surface roller cross-sectional diameter is even, and axle center crooked (as shown in Figure 1).When paper rotates by the cambered surface roller, paper is prolonged the axial elongation of arc shaft.But because gum cover consists of some sections straight rollers, have each other certain axial displacement, paper easily produces fold.
Intensity and the service life of prior art cambered surface roller in order to increase gum cover, what have need to be provided with steel wire at the internal layer of gum cover.This has just caused the cost of cambered surface roller very expensive, complex structure, very difficult when dissembling inspection.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of cambered surface roller novel, simple in structure, with low cost, convenient disassembly, and can ensure the function realized the paper axial tension.
To achieve these goals, the technical scheme of the utility model cambered surface roller is as follows:
The utility model cambered surface roller, cross section is circular, comprises installation portion and the middle roll body section at two ends.The cross section diameter of the both sides of the close installation portion of roll body section is larger than the cross section diameter of the interlude of roll body section.Installation portion and roll body section connect as one, and axle center linearly, is formed by the stainless steel bars machining.
Preferably, the axial surperficial sideline of described roll body section is symmetrical arcs of recesses.
Preferably, the axial surperficial sideline of described roll body section is symmetrical conical socket shape.
Preferably, described roll body section comprises roll body always, and near the parcel band on straight roll body that is wrapped in of installation portion.
The utility model cambered surface roll structure is simple, by simple machine cut, gets final product machine-shaping, with low cost, can realize the function of traditional cambered surface roller, and avoids paper to produce fold.
The accompanying drawing explanation
The structural representation that Fig. 1 is prior art cambered surface roller;
The structural representation that Fig. 2 is embodiment mono-cambered surface roller;
The structural representation that Fig. 3 is embodiment bis-cambered surface rollers;
The structural representation that Fig. 4 is embodiment tri-cambered surface rollers.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is further described:
Embodiment mono-:
As shown in Figure 2, be the present embodiment cambered surface roller, cross section is circular, comprises installation portion and the middle roll body section at two ends.The cross section diameter of the both sides of the close installation portion of roll body section is larger than the cross section diameter of the interlude of roll body section.Installation portion and roll body section connect as one, and axle center linearly, is formed by the stainless steel bars machining.The axial surperficial sideline of described roll body section is symmetrical arcs of recesses.
Embodiment bis-:
As shown in Figure 3, be the present embodiment cambered surface roller, cross section is circular, comprises installation portion and the middle roll body section at two ends.The cross section diameter of the both sides of the close installation portion of roll body section is larger than the cross section diameter of the interlude of roll body section.Installation portion and roll body section connect as one, and axle center linearly, is formed by the stainless steel bars machining.The axial surperficial sideline of described roll body section is symmetrical conical socket shape.
Embodiment tri-:
As shown in Figure 4, be the present embodiment cambered surface roller, cross section is circular, comprises installation portion and the middle roll body section at two ends.The cross section diameter of the both sides of the close installation portion of roll body section is larger than the cross section diameter of the interlude of roll body section.Described roll body section comprises roll body always, and near two the parcel bands on straight roll body that are wrapped in of installation portion.Installation portion connects as one with straight roll body, and axle center linearly, is formed by the stainless steel bars machining.The cambered surface roller of the present embodiment is specially adapted to the sheet processing that breadth is narrow.
The cambered surface roller of above-described embodiment one to three, its installation portion is contained on bearing.During rotation, due to the diameter difference at each position of roll body section, its linear resonance surface velocity is also not identical, can realize paper prolonged to the cambered surface roll shaft to stretching.
Claims (5)
1. cambered surface roller, cross section is circular, comprises installation portion and the middle roll body section at two ends, it is characterized in that: the cross section diameter of the both sides of the close installation portion of described roll body section is larger than the cross section diameter of the interlude of roll body section.
