Chicken wing de-boning machine

摘要

An apparatus for extracting a bone from a cut of meat comprises a frusto-conical blade against which the cut of meat is pushed in the axial direction of, and in line with the bone. The apical opening edge of the blade cuts and spreads the meat around the bone, allowing the bone to pass through the blade while the meat is crunched against the wall of the blade and its backing plate. The bone is grabbed by a pair of jaws terminated by barbed cylinders that rotate in opposite directions to further extract the bone from the cut of meat. The movements of the jaw and of a lever that pushes the cut of meat towards the blade are synchronized by a single camshaft mounting eccentric wheels acting on both the jaws and the pushing lever. These movements are driven for safety by the pull of coil springs. Electrical motors only return the jaws and lever to their rest position.
