Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, in particular to a logistics roller which is convenient for overhaul and disassembly. Background Art

[0002] A roller refers to a cylindrical object that can rotate in a machine. In a machine, a common power source (such as an electric motor) is often used to drive the roller to drive other materials forward, or to process materials by applying pressure generated by the roller. In logistics transportation, roller conveyors are often used to transport packages.

[0003] In the existing logistics sorting and transportation, a belt conveyor is usually required to convey express items. A traditional belt conveyor needs to use rollers as the main conveying components. For example, a roller disclosed in Chinese Patent Publication No. "CN207192192U" includes a cylinder body and a rotating shaft. A connecting sleeve is nested at each end of the cylinder body, and the connecting sleeve is tightly fitted with the inner wall of the cylinder body. The rotating shaft penetrates through the cylinder body, and both ends of the rotating shaft pass through the connecting sleeve respectively. A bearing is provided between the rotating shaft and the connecting sleeve, and the rotating shaft rotates relative to the cylinder body through the bearing. A limiting device for limiting the rotating shaft is provided on the bearing.

[0004] Since most rotating shafts penetrate through the roller and are fixedly connected to each other through a fixing component, when disassembling, the entire rotating shaft needs to be pulled out to take out the roller. It does not have a quick-disassembly structure, and the disassembly is relatively cumbersome, which brings certain inconvenience. Summary of the Utility Model
