Abstract
The utility model discloses a soft press polish structure, which comprises a hard roller and a soft roller; the surfaces of the hard roller and the soft roller are adjacent and have the same tangent plane; the radius of the hard roller is R, the radius of the soft roller is R, and the R is smaller than R; the rotating speed of the soft roller is R/R times of that of the hard roller; the surface of the soft roller is provided with a hard grease layer and a rebound layer from inside to outside; the hard grease layer and the rebound layer are both in a ring shape and are coated on the surface of the soft roller. The utility model has the advantages that: in the technical scheme, the radius of the hard roller is R, the radius of the soft roller is R, and the R is smaller than the R; the rotating speed of the soft roller is R/R times of that of the hard roller; the speed of a motor vehicle that just so can keep the tangent plane is unanimous for the paper business turn over is even, can not take place fracture or fold, and soft roller surface from inside to outside is equipped with the fat layer and kick-backs the layer, has just so realized the technical requirement of soft press polish, and the paper tightness is unanimous and even, reaches the technical requirement of transfer printing paper.
Description
Technical Field
The utility model relates to a press polish technique especially relates to a soft press polish structure.
Background
In current transfer paper production processes, where there is a certain requirement for the tightness of the paper, the steel-steel nip during hard calendering is not uniform in pressure if there are uneven patches in the sheet. When too many sheets, high thickness patches or flocculated lumps are entering the nip, where the pressure will be at its most and the surrounding areas are lower. Therefore, a soft calendering structure capable of keeping the paper tightness consistent must be developed, and the technical scheme the same as the utility model is not found after retrieval.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a soft press polish structure that can keep the paper degree of tightness unanimous, solves one or more among the above-mentioned prior art problem.
In order to solve the technical problem, the utility model discloses a technical scheme be: the soft calendaring structure has the innovation points that: comprises a hard roller and a soft roller; the surfaces of the hard roller and the soft roller are adjacent and have the same tangent plane;
the radius of the hard roller is R, the radius of the soft roller is R, and the R is smaller than R; the rotating speed of the soft roller is R/R times of that of the hard roller;
the surface of the soft roller is provided with a hard grease layer and a rebound layer from inside to outside; the hard grease layer and the rebound layer are both in a ring shape and are coated on the surface of the soft roller.
In some embodiments the thickness of the stiff layer is 1.5 times the thickness of the resilient layer.
In some embodiments, the hard roll is coated with a hard polishing layer having a thickness of 1-2 filaments.
In some embodiments, the hard polishing layer has a hardness greater than the hard roll hardness.
The utility model has the advantages that: in the technical scheme, the radius of the hard roller is R, the radius of the soft roller is R, and the R is smaller than the R; the rotating speed of the soft roller is R/R times of that of the hard roller; the speed of a motor vehicle that just so can keep the tangent plane is unanimous for the paper business turn over is even, can not take place fracture or fold, and soft roller surface from inside to outside is equipped with the fat layer and kick-backs the layer, has just so realized the technical requirement of soft press polish, and the paper tightness is unanimous and even, reaches the technical requirement of transfer printing paper.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a schematic structural diagram of a soft calendering structure of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in the figure, the embodiment of the utility model provides a include:
a soft calendering structure comprises a hard roller 1 and a soft roller 2; the surfaces of the hard roller 1 and the soft roller 2 are adjacent and have the same tangent plane; the radius of the hard roller 1 is R, the radius of the soft roller 2 is R, and the R is smaller than R; the rotating speed of the soft roller 2 is R/R times of that of the hard roller 1; the surface of the soft roller 2 is provided with a hard grease layer 21 and a rebound layer 22 from inside to outside; the hard grease layer 21 and the rebound layer 22 are both in a ring shape and are coated on the surface of the soft roller 2.
In the technical scheme, the radius of a hard roller 1 is R, the radius of a soft roller 2 is R, and the R is smaller than the R; the rotating speed of the soft roller 2 is R/R times of that of the hard roller 1; therefore, the speed of the tangent plane can be kept consistent, the paper can enter and exit uniformly, no fracture or wrinkle occurs, the hard grease layer 21 and the rebound layer 22 are arranged on the surface of the soft roller 2 from inside to outside, the technical requirement of soft calendering is met, the tightness of the paper is consistent and uniform, and the technical requirement of transfer paper is met.
In some embodiments the thickness of the hardcoat layer 21 is 1.5 times greater than the thickness of the resilient layer 22; the technical scheme ensures that the rebound rate of the soft roller 2 is controlled in the optimal range, and the consistent effect of the tightness of the transfer paper is optimal.
In some embodiments, the surface of the hard roller 1 is plated with the hard polishing layer 11, and the thickness of the hard polishing layer 11 is 1-2 filaments.
In some embodiments, the hardness of the hard polishing layer 11 is greater than the hardness of the hard roll 1; the technical scheme can ensure that the coefficient of the hard roller 1 is unchanged and even higher.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
