The invention relates to an automatic treatment and recycling machine for a waste aluminum profile generated in wrought aluminum alloy processing. The automatic treatment and recycling machine comprises a bottom plate, wherein a cleaning conveying device, an amount limiting device and a flattening device are mounted in sequence from front to back on the bottom plate. By adopting the automatic treatment and recycling machine, the difficulties that the waste aluminum profile is not comprehensively cleaned manually while the waste aluminum profile is treated manually, waste aluminum profile processing treatment is affected by residual dirt, operators can be hurt by splashed chippings when the waste aluminum profile is beaten by using a beating tool, potential safety hazard can be caused, waste aluminum profiles of different lengths need to cut into a unified size manually, the waste aluminum profiles need to be beaten and flattened for multiple times manually, conventional large-size waste aluminum profile recycling equipment is high in cost, great energy consumption is needed when a small batch of waste aluminum profiles are treated, resource waste is caused, manual waste aluminum profile processing is poor in stability, large in working intensity and low in working efficiency, and the like, are solved, and an automatic waste aluminum profile treatment function is achieved.
