AI Technical Summary
The high hardness of existing rubber rollers leads to insufficient wear resistance and cannot be pressed in some positions, which affects the use effect.
The intermediate rubber layer is introduced into the structure of the rubber roller, with a hardness of 20-25°, which is located between the bottom rubber layer and the roller surface rubber layer, forming a hierarchical structure of the bottom rubber layer 55-60°, the intermediate rubber layer 20-25°, and the roller surface rubber layer 35-40° to optimize the hardness distribution of the rubber roller.
The wear resistance of the rubber roller is improved, and the hardness is reduced, avoiding the problem of incoming position in the recessed position due to excessive hardness.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber rollers, and particularly relates to a rubber roller structure. Background Art
[0002] A rubber roller generally includes a roller core and a rubber layer coated outside the roller core. In order to ensure the wear resistance of the rubber roller, the hardness of the existing rubber layer of the rubber roller is generally relatively high. A relatively high hardness of the rubber roller may cause some recessed positions of products not to be pressed. Therefore, how to improve the wear resistance of the rubber roller and reduce the hardness of the rubber roller is an urgent problem to be solved. Summary of the Utility Model
[0003] Aiming at the defects in the prior art, the utility model provides a rubber roller structure to improve the wear resistance of the rubber roller while reducing the hardness of the rubber roller.
[0004] The utility model provides a rubber roller structure, including a roller core and a rubber layer coated outside the roller core;
[0005] The rubber layer includes a bottom rubber layer, an intermediate rubber layer and a roller surface rubber layer which are arranged in sequence from inside to outside. The hardness of the bottom rubber layer is 55 - 60°, the hardness of the intermediate rubber layer is 20 - 25°, and the hardness of the roller surface rubber layer is 35 - 40°.
[0006] Further, the thickness of the bottom rubber layer is 2 mm - 10 mm.
[0007] Further, the thickness of the intermediate rubber layer is 5 - 30 mm.
[0008] Further, the thickness of the roller surface rubber layer is 5 - 30 mm.
[0009] Further, the roller core is a metal roller core.
[0010] Further, the rubber layer is fixedly adhered to the outside of the roller core through an adhesive.
[0011] The beneficial effects of the utility model are reflected in:
[0012] The lower the hardness of the rubber layer, the less wear-resistant it is, and the higher the hardness, the more wear-resistant it is. If the rubber layer with a hardness of 20 - 25° is directly used without adding a rubber layer with a hardness of 35 - 40°, the rubber roller is likely to be easily worn. If the rubber layer with a hardness of 35 - 40° is directly used, then the hardness is too high, which may cause some recessed positions of products not to be pressed. In this application, an intermediate rubber layer with a hardness of 20 - 25° is added between the roller surface rubber layer with a hardness of 35 - 40° and the bottom rubber layer with a hardness of 55 - 60°, which can reduce the hardness of the roller surface rubber layer with a hardness of 35 - 40° to 30 - 35°, and at the same time have the wear resistance of the roller surface rubber layer with a hardness of 35 - 40°. In this way, while improving the wear resistance of the rubber roller, the hardness of the rubber roller is reduced. Brief Description of the Drawings

[0018] The following will describe in detail the embodiments of the technical solutions of the present invention in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and therefore are only examples and cannot be used to limit the protection scope of the present invention.
[0019] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.
[0020] As Figures 1 - 3 shown, an embodiment of the present invention provides a rubber roll structure, including a roll core 100 and a rubber layer 200 coated outside the roll core 100. The rubber layer 200 is fixedly adhered to the outside of the roll core 100 through an adhesive.
[0021] The roll core 100 can be a metal roll core 100 (such as a steel roll core 100 and an aluminum alloy roll core 100) or a non-metal roll core 100 (such as a fiberglass roll core 100 and a ceramic roll core 100), and preferably a metal roll core 100.
[0022] The rubber layer 200 includes a base rubber layer 210, an intermediate rubber layer 220, and a roll surface rubber layer 230 arranged in sequence from the inside to the outside. The hardness of the base rubber layer 210 is 55 - 60°, the hardness of the intermediate rubber layer 220 is 20 - 25°, and the hardness of the roll surface rubber layer 230 is 35 - 40°. The above hardness ranges use the Shore A hardness.
[0023] In this embodiment, the thickness of the base glue layer 210 is preferably 2 mm - 10 mm.
[0024] In this embodiment, the thickness of the middle rubber layer 220 is preferably 5 - 30 mm.
[0025] Furthermore, the thickness of the roller surface rubber layer 230 is preferably 5 - 30 mm.
[0026] The lower the hardness of the rubber layer 200, the less wear-resistant it is, and the higher the hardness, the more wear-resistant it is. If a rubber layer 200 with a hardness of 20 - 25° is directly used without adding a rubber layer 200 with a hardness of 35 - 40°, the rubber roller will be easily worn. If a rubber layer 200 with a hardness of 35 - 40° is directly used, the hardness will be too high, resulting in some concave positions of the products not being pressed. In this application, a middle rubber layer 220 with a hardness of 20 - 25° is added between the roller surface rubber layer 230 with a hardness of 35 - 40° and the base glue layer 210 with a hardness of 55 - 60°, which can reduce the hardness of the roller surface rubber layer 230 with a hardness of 35 - 40° to 30 - 35°, and at the same time have the wear-resistant performance of the roller surface rubber layer 230 with a hardness of 35 - 40°. In this way, while improving the wear resistance of the rubber roller, the hardness of the rubber roller is reduced.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
