Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a new type of carbon fiber rubber roller. Background Art

[0002] An ordinary rubber roller includes a rubber sheet, a metal cylinder body and metal axles. The metal axles are generally welded to both axial ends of the metal cylinder body, and the rubber sheet is coated on the outside of the metal cylinder body. With the development of carbon fiber production technology, carbon fiber is also widely used in the field of rollers. Replacing the metal cylinder body with a carbon fiber cylinder body can reduce the weight of the roller while ensuring the strength of the roller, which has many advantages.

[0003] For a carbon fiber rubber roller, its cylinder body is made of carbon fiber, the rubber coating layer is arranged on the surface of the carbon fiber cylinder body, and the axles are embedded at both axial ends of the carbon fiber cylinder body. Since carbon fiber and the axles cannot be welded, the axles are generally connected to the carbon fiber cylinder body by bonding and tensioning. This connection method is not convenient for disassembling the carbon fiber cylinder body and the axles, and its stability is not as high as welding, and the axles may become loose. Content of the Utility Model

[0004] To solve the problems mentioned in the background art, the purpose of the utility model is to provide a new type of carbon fiber rubber roller.

[0005] To achieve the above goal, the technical solution of the utility model is as follows:

[0006] A new type of carbon fiber rubber roller includes a carbon fiber cylinder body, two axles, a central shaft rod, two connecting cylinders and two limit nuts. A film is coated on the outside of the carbon fiber cylinder body. Threads are engraved on the circumferential surface of the connecting cylinder. The two connecting cylinders are respectively connected to the two port ends of the carbon fiber cylinder body by threads, and the tightening directions of the two connecting cylinders are opposite. A sealing plate is fixedly connected to one end of the connecting cylinder facing away from the opposite connecting cylinder. The two sealing plates respectively abut against the two port ends of the carbon fiber cylinder body. The central shaft rod is coaxially arranged inside the carbon fiber cylinder body. The two axial ends of the central shaft rod respectively abut against the two sealing plates. The two axial ends of the central shaft rod are respectively connected with stud bolts. The two stud bolts respectively penetrate through the two sealing plates. The two limit nuts are respectively threadedly connected to the two stud bolts and respectively abut against the opposite surfaces of the two sealing plates. The flange plates of the two axles are respectively fixedly connected to the two sealing plates by a plurality of bolts. An empty groove for accommodating the stud bolt and the limit nut is provided on the flange plate of the axle.

[0007] Furthermore, a central through hole for accommodating the stud bolt is provided at the center of the sealing plate. A plurality of screw holes are evenly distributed along the circumferential direction of the edge of the sealing plate. A plurality of mounting holes are evenly distributed along the circumferential direction of the edge of the flange plate of the axle.

[0008] The beneficial effects of the present utility model are as follows: The connecting cylinder is connected to the port of the carbon fiber cylinder body by threads and locked by the central shaft rod, and then the shaft head is connected to the sealing plate by bolts. Compared with the traditional methods of bonding or expanding and tightening to connect the shaft head, it is not only convenient to disassemble the carbon fiber cylinder body and the shaft head, but also can ensure that the shaft head will not loosen, effectively improving the stability of the shaft head installation.
