Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rollers, and more specifically to a steel roller. Background Technology
[0002] Steel rollers are rollers used in various equipment and machinery, usually made of steel, and are generally used for conveying, pressing, extruding, and transporting. In the production of transparent films, because the material itself is very thin, and theoretically the thickness is not completely uniform (some areas are thicker than others), the paired steel rollers can damage the transparent film during transport, and in severe cases, even damage the steel rollers themselves. Therefore, we provide a flexible steel roller. Utility Model Content
[0003] The purpose of this invention is to provide a flexible steel roller to overcome the aforementioned shortcomings. Its roller surface, while maintaining rigidity, has a high degree of smoothness and elasticity, providing a certain degree of protection for both the material and the steel roller itself during use. It is particularly suitable for the production of transparent film materials.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0005] A flexible steel roller includes a roller body and roller shafts. The roller shafts are fixedly installed at the center of both ends of the roller body. The surface of the roller body is covered with a rubber layer, and a steel strip layer is covered on the surface of the rubber layer.
[0006] Preferably, the surface of the steel strip layer is coated or permeated with a chromium plating layer.
[0007] Preferably, the surface of the steel strip layer is coated or permeated with a ceramic layer.
[0008] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:
[0009] 1. By sequentially setting a rubber layer and a steel strip layer on the surface of the roller, the steel strip layer on the surface ensures the rigidity of the steel roller, while the rubber layer inside the steel strip layer gives the steel roller a certain degree of flexibility. During use, the flexible steel roller can provide good protection for materials, especially film materials, and prevent damage to the material surface. In addition, it can also provide a certain degree of protection for the steel roller itself and prevent deformation and damage to the steel roller itself.
[0010] 2. Coating or penetrating a chromium plating layer onto the surface of the steel strip layer helps to increase the smoothness of the roller surface, which is beneficial for the production of transparent film materials. Attached Figure Description
[0011] Figure 1This is a schematic diagram of the structure of this utility model.
[0012] 1. Roller body; 2. Roller shaft; 3. Rubber layer; 4. Steel strip layer. Detailed Implementation
[0013] Depend on Figure 1 As shown, the flexible steel roller includes a roller body 1 and roller shafts 2. The roller shafts 2 in pairs are fixedly installed at the center of both ends of the roller body 1. The surface of the roller body 1 is covered with a rubber layer 3, and a steel strip layer 4 is covered on the surface of the rubber layer 3. This ensures both rigidity and flexibility. The surface of the steel strip layer is coated or permeated with a chrome plating layer, which can effectively improve the smoothness of the roller body surface. A ceramic layer can also be coated or permeated on the surface of the steel strip layer to improve the hardness of the roller body surface.
Claims
1. A flexible steel roll comprising a roll body and roll shafts, a pair of said roll shafts being fixedly mounted at the center of both ends of the roll body, characterized in that: The surface of the roller body is coated with a rubber layer, and the surface of the rubber layer is coated with a steel belt layer.
2. The flexible steel roll of claim 1, wherein: The surface of the steel belt layer is coated or permeated with a chromium plating layer.
3. The flexible steel roll of claim 1, wherein: The surface of the steel belt layer is coated or permeated with a ceramic layer.
