Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber rollers and rubber rollers, and particularly relates to a split carbon fiber roller. Background Art

[0002] Carbon fiber rollers are high-performance roller products that use carbon fiber as the main reinforcement material and are compounded through a resin matrix. Carbon fiber has an extremely high strength-to-weight ratio and excellent fatigue resistance. Carbon fiber rollers are widely used in high-end manufacturing industries such as printing, papermaking, textiles, new energy, aerospace, military and many other fields. They are mainly used in transmission, tension control, calendering, coating and other process links. In order to improve the performance of carbon fiber rollers, rubber materials are added to them according to different usage scenarios. However, most common carbon fiber rollers are one-piece structures, which makes it impossible to disassemble and assemble the carbon fiber rollers according to actual needs. In addition, one-piece carbon fiber rollers usually need to be formed in one step through complex winding, curing and other processes, which has high requirements for production equipment and technology, and the production cost and difficulty are relatively large.

[0003] Secondly, if a carbon fiber roller is damaged in a certain part, it is not as easy to repair as a split type or a carbon fiber roller with replaceable parts because of its integrated structure. It is likely to need to be replaced as a whole, thus increasing the maintenance cost. Due to its integrated structure, when the carbon fiber roller reaches the end of its service life or is seriously damaged and needs to be scrapped, it is difficult to effectively disassemble and recycle it, which may increase the cost and difficulty of waste disposal.

[0004] In summary, there are some problems in the use of the integrated carbon fiber roller, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
