High-efficiency machining circulating feeding machine

The invention discloses a high-efficiency machining circulating feeding machine which comprises a machine base, a rotating base, a first motor, a feeding mechanism, a conveying sliding groove base, an output port, a shell, a push block, a first oil cylinder, a partition plate, a feeding cavity and a charging mechanism. A plurality of materials are stacked and placed on the supporting base and abut against the limiting base, then the second oil cylinder extends to enable the pushing plate to move rightwards, the stacked material sets are pushed into the feeding cavity together to be stored, and therefore the convenience of material supplementing is improved; a plurality of material groups can be isolated through the partition plates, so that the number of stored materials in the material supply cavity is increased, and inconvenience and trouble caused by frequent supplement of the materials by workers are avoided; when the push-out block moves upwards to push out materials, the L-shaped locking block can move
