Description

Technical Field

[0001] The utility model belongs to the field of rubber roller replacement, and particularly relates to a rubber roller with a housing that is convenient to replace. Background Art

[0002] A rubber roller generally consists of an outer rubber layer, a hard rubber layer, a metal core, a roller neck, and ventilation holes. Its processing includes processes such as roller core sandblasting, bonding treatment, rubber pasting and forming, cloth wrapping, wire winding, vulcanization in a vulcanizing tank, and surface processing. Rubber rollers are mainly used in papermaking, printing and dyeing, printing, grain processing, metallurgy, plastic processing, etc. Rubber rollers utilize the characteristics of the rubber body and are applied in various industrial productions.

[0003] Some rubber rollers with housings that are convenient to replace have been specifically developed in the prior art. For example, the Chinese patent with the publication number "CN217814533U" discloses "a rubber roller with a rubber surface that is convenient to replace". When installing the rubber surface main body, only by sliding the positioning rod into the positioning groove can the positioning of the rubber surface main body be completed, which can effectively reduce the time for replacing the rubber surface main body. At the same time, in the bearing position, the input device can be fixed to the bearing position either by screwing the bolt on the input device into the threaded hole or by inserting the limiting block into the input device, increasing the connection methods of the rubber roller and improving the versatility of the rubber roller.

[0004] Although the positioning of the rubber surface main body can be completed by sliding the positioning rod into the positioning groove, which can effectively reduce the time for replacing the rubber surface main body and improve the versatility of the rubber roller, in the above structure, the installation steps will be increased during installation, increasing the installation time, and it cannot effectively achieve rapid installation and disassembly. Some particulate ash layers or stains will adhere to the rubber surface main body during the use of the rubber surface main body, which will damage the printed paper during the next use and cannot effectively clean the ash layer and stains.
