Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying rollers, and particularly relates to a high polymer rubber roller. BACKGROUND

[0002] In the conveying process of steel strips, conveying rollers are usually used for guiding the conveying of the steel strips. The friction between the conveying rollers and the steel strips is relatively large, so that the service life of the wear-resistant layer of the conveying rollers is relatively short. Therefore, the wear-resistant layer needs to be replaced regularly. However, the wear-resistant layer is installed on the guide roller through the tensioning action of the material, so that the wear-resistant layer is relatively difficult to disassemble and assemble. CONTENT OF THE UTILITY MODEL

[0003] In view of the defects in the prior art, one of the purposes of the present application is to provide a high polymer rubber roller which has the advantage that the wear-resistant layer is more convenient to disassemble and assemble.

[0004] The above purpose of the present application is achieved by the following technical scheme:

[0005] The high polymer rubber roller comprises a body, the body comprises a rubber wear-resistant layer and a supporting part, the rubber wear-resistant layer is used for increasing the wear resistance of the body, and the supporting part is used for adjusting the tension of the rubber wear-resistant layer.

[0006] By adopting the above technical scheme, the supporting part adjusts the tension of the rubber wear-resistant layer, so that the rubber wear-resistant layer is in a relaxed state when the rubber wear-resistant layer is replaced, thereby making the installation and disassembly of the rubber wear-resistant layer more easy.

[0007] In a preferred example, the body further comprises a shaft and a supporting column, the supporting part is sleeved on the supporting column, the rubber wear-resistant layer is sleeved on the supporting part, the supporting part is provided with an adjusting cavity and a channel, the channel is used for passing the medium, and the adjusting cavity expands or shrinks along with the volume change of the medium.

[0008] By adopting the above technical scheme, the supporting part is sleeved on the supporting column, and the rubber wear-resistant layer is sleeved on the supporting part, so that the supporting part is located between the supporting column and the rubber wear-resistant layer. When the adjusting cavity is filled with the medium, the rubber wear-resistant layer is in a tension state so that the conveying roller can work normally. When the medium is discharged from the adjusting cavity, the rubber wear-resistant layer is in a relaxed state, so that the rubber wear-resistant layer is easily detached from the supporting part.

[0009] In a preferred example, the supporting part is made of a flexible material.

[0010] By adopting the above technical scheme, the function that the supporting part can expand or shrink is realized.

[0011] In a preferred example, a plurality of flow guides are arranged between the shaft and the supporting column, and the flow guides are used for guiding the heat to be conducted out of the body.

[0012] By adopting the technical scheme, the heat generated by the rubber wear-resistant layer and the steel belt is led out under the action of the flow guide piece, so that the aging speed of the rubber wear-resistant layer is slowed down, thereby prolonging the service life of the conveying roller.

[0013] In a preferred example, the flow guide piece is arranged in a spiral shape between the shaft and the support column.

[0014] In a preferred example, the pitch of the spiral flow guide piece is 0.75-1 times the length of the body.

[0015] By adopting the technical scheme, the pitch of the spiral flow guide piece is 0.75-1 times the length of the body, so that the heat dissipation effect of the flow guide piece is better. BRIEF DESCRIPTION OF DRAWINGS

[0020] The application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figs. 1 to 3 A high polymer rubber roller disclosed by the application includes a body 1, the body 1 includes a rubber wear-resistant layer 2, a support part 5, a shaft 3, a support column 4, and a flow guide piece 6, the support part 5 is sleeved on the support column 4, the rubber wear-resistant layer 2 is sleeved on the support part 5, so that the support part 5 is located between the support column 4 and the rubber wear-resistant layer 2, and the shaft 3 and the support column 4 are provided with a plurality of flow guide pieces 6.

[0022] The rubber wear-resistant layer 2 is used to increase the wear resistance of the body 1, the support part 5 is used to adjust the tension of the rubber wear-resistant layer 2, so that the rubber wear-resistant layer 2 is in a relaxed state when the rubber wear-resistant layer 2 is replaced, and the flow guide piece 6 is used to guide heat out of the body 1, in this embodiment, the material of the rubber wear-resistant layer 2 can be high polymer rubber.

[0023] The support part 5 is made of flexible material, so that the support part 5 can expand or shrink. The support part 5 is provided with an adjusting cavity 51 and a channel 52. The channel 52 passes through the hole on the support column 4 and is used for passing medium. The adjusting cavity 51 expands or shrinks with the volume change of the medium. When the adjusting cavity 51 is filled with the medium, the rubber wear-resistant layer 2 is in a tension state, so that the conveying roller can work normally. When the medium is discharged from the adjusting cavity 51, the rubber wear-resistant layer 2 is in a relaxed state, so that the rubber wear-resistant layer 2 is easily separated from the support part 5. In the embodiment, the material of the support part 5 can be flexible material such as rubber or silica gel, and the medium can be gas or liquid.

[0024] The guide vane 6 is arranged in a spiral shape between the shaft 3 and the support column 4. The pitch of the spiral guide vane 6 is 0.75-1 times the length of the body 1, so that the heat dissipation effect of the guide vane 6 is better. The guide cavity is used for guiding heat to be conducted out of the body 1 and saving material. In the embodiment, the number of the guide vanes 6 is three.

[0025] When the rubber wear-resistant layer 2 is installed, the medium in the adjusting cavity 51 is discharged from the channel 52, so that the adjusting cavity 51 is in a shrinking state. The outer diameter of the support part 5 is smaller than the inner diameter of the rubber wear-resistant layer 2, so that the rubber wear-resistant layer 2 is easily sleeved on the support part 5. When the rubber wear-resistant layer 2 is disassembled, the medium is filled into the adjusting cavity 51 through the channel 52, so that the adjusting cavity 51 is in an expanding state and the channel 52 is blocked. The outer diameter of the support part 5 is in abutment with the inner diameter of the rubber wear-resistant layer 2, so that the rubber wear-resistant layer 2 is in a tension state, and the conveying roller can work normally.

[0026] The body 1 is installed on other structures through the shaft 3 and rotates under the action of the steel belt. The guide vane 6 rotates with the shaft 3, so that the heat generated between the rubber wear-resistant layer 2 and the steel belt is discharged from the body 1. Therefore, the aging speed of the rubber wear-resistant layer 2 is slowed down, and the service life of the body 1 is longer.

[0027] The implementation principle of the embodiment is that the support part 5 adjusts the tension of the rubber wear-resistant layer 2. When the rubber wear-resistant layer 2 is replaced, the rubber wear-resistant layer 2 is in a relaxed state, so that the installation and disassembly of the rubber wear-resistant layer 2 are easier. The guide vane 6 dissipates heat for the rubber wear-resistant layer 2, so that the aging speed of the rubber wear-resistant layer 2 is slowed down, and the service life of the conveying roller is longer.

[0028] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application. Therefore, equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
