The invention discloses a food cutting machine, which comprises a body. The body is provided with a feeding cylinder, a wringing cylinder is installed in the feeding cylinder and is connected to a power drive rod, the wringing cylinder is sleeved on the power drive rod, the front end of the power drive rod passes through a casing hole at the rear end face of the wringing cylinder and is then sleeved with a rubber ring preventing the wringing cylinder from slipping forward, a limiting baffle plate is disposed on the power drive rod behind the wringing cylinder, and bumps are evenly distributed on the front end face of the limiting baffle plate circumferentially. The downstream sides of the bumps in the rotation direction are equipped with tilted gaps. The rear end face of the wringing cylinder has sloping panels fitted to the tilted gaps, when the power drive rod drives the wringing cylinder to rotate through the tilted gaps and the sloping panels, the tilted gaps cooperate with the sloping panels to provide a backward component force to the wringing cylinder so as to block the wringing cylinder from slipping forward. The food cutting machine provided by the invention has the characteristics of simple structure, good effect of avoiding wringing cylinder slip, small wear and low noise, and convenient assembly and disassembly and cleaning.
