Description

Technical Field

[0001] The utility model relates to the field of rollers, and specifically relates to a high-strength aluminum roller. Background Technique

[0002] A roller refers to an object in a mechanical structure that is cylindrical and can rotate. In machinery, a common driving source is used to drive the roller to drive other materials placed on the roller to move, or to apply pressure to the materials using the roller for processing.

[0003] After retrieval, the Chinese utility model patent CN213291424U discloses a high-strength roller, which relates to the field of rollers and includes a central shaft. A connecting ring is connected to the outside of the central shaft, and a fixing ring is arranged on the outside of the connecting ring. A cavity is arranged on the outside of the fixing ring, and reinforcing ribs are arranged inside the cavity. One end of the reinforcing rib is connected to an inner roller, and an outer roller is arranged on the outside of the inner roller. Both ends of the outer roller are connected with end caps, and through holes are arranged inside the end caps. A scale is arranged on the outside of the end cap on one side of the through hole. Through the arrangement of the central shaft, connecting ring, fixing ring, inner roller, and outer roller, the roller is not a single-layer structure. An inner roller is arranged inside the outer roller, and the addition of the inner roller makes the outer roller have better compressive resistance and is not easily damaged. The reinforcing ribs, fixing ring, and connecting ring inside the inner roller can also enhance the strength of the outer roller and reduce the possibility of its breakage.

[0004] The technical solution in this application document still has deficiencies: The roller is an integral structure and cannot replace the outer roller, and cannot replace the reinforcing structure in the high-strength aluminum roller alone, nor can it replace a single reinforcing rib in the reinforcing structure. When a component in the high-strength aluminum roller is damaged, the entire aluminum roller needs to be replaced, and the damaged part cannot be replaced separately, resulting in too high maintenance costs for the high-strength aluminum roller. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-strength aluminum roller to solve the problems raised in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: a high-strength aluminum roller, comprising a central roller, an outer roller and end caps. A fixed inner roller is fixedly sleeved outside the central roller. A reinforcing cylinder is sleeved outside the fixed inner roller.

The entire reinforcing cylinder can be disassembled and replaced by the connection block installed on the inner ring wall of the inner connecting cylinder being slidably connected with the connection groove provided on the outer ring wall of the fixed inner roller. Through the docking blocks A and B installed at both ends of the reinforcing rib, the docking block A is slidably connected with the docking groove A provided on the inner ring wall of the outer connecting cylinder, and the docking block B is slidably connected with the docking groove B provided on the outer ring wall of the inner connecting cylinder, and a single deformed and damaged reinforcing rib can be disassembled and replaced. After the replacement is completed, install the end caps at both ends, so that the limiting rods installed on the end caps are inserted into the limiting grooves provided on the ports of the outer roller, the screw holes A provided on the end faces of the fixed inner roller are aligned with the screw holes B provided on the end caps, and then screw in the screws for fixation, which can specifically replace the damaged parts in the high-strength aluminum roller, avoid the problem of needing to replace the entire aluminum roller when the high-strength aluminum roller is damaged, and avoid the too high maintenance cost of the high-strength aluminum roller.

[0008] In a further embodiment, screw holes A are respectively provided on both end faces of the fixed inner roller. Screw holes B are provided on the end caps. The number and positions of the screw holes A and B are the same. The screw holes A provided on the end faces of the fixed inner roller are aligned with the screw holes B provided on the end caps, and then screw in the screws for fixation.

[0009] In a further embodiment, limiting grooves are respectively formed at both ends of the outer roller, and limiting rods are installed on the end covers. The limiting rods are slidably connected to the limiting grooves, so that the limiting rods installed on the end covers are inserted into the limiting grooves formed at the ports of the outer roller for limiting and fixing.
