[0002] Rubber rollers are roll-shaped products made of metal or other materials as the core and rubber covered by vulcanization. According to the surface morphology, they can be divided into: flat rollers and patterned rubber rollers; EPDM rubber rollers can be divided into: butyl rubber rollers, nitrile rubber rollers, polyurethane rubber rollers and silicone rubber rollers according to the materials.

[0003] In the textile industry, textile rubber rollers are indispensable equipment, but they have a service life. After a period of time, the outer rubber layer will wear out, and the hardness and toughness of the rubber roller components will gradually deteriorate, which will affect the quality of the textiles and even damage the textiles. At this time, the rubber rollers can no longer be used and need to be replaced with new ones.

[0004] However, the existing rubber rollers are generally integral structures, which are inconvenient to install and disassemble. When replacing, it is generally necessary to remove all the connecting parts on the textile support before removing or installing the rubber roller. This requires the cooperation of multiple people and takes a long time to install and disassemble, resulting in a waste of resources and increasing expenditure costs.

[0005] Therefore, a textile rubber roller that is easy to disassemble and assemble is needed, which can be easily disassembled and replaced. Summary of the invention
