Description

Assembled separating knife structure for meat grinder and assembling method Technical Field The invention relates to the technical field of food processing machinery, in particular to an assembled separating knife structure for a meat grinder and an assembling method. Background In the prior art, a meat grinder is one of the very common devices in the meat processing process, in slaughtering industry and catering industry, different cutter products are used for different meats, the cutters are generally driven to rotate by an electric driving mechanism through a rotating shaft in a matched mode, in the cutter for cutting the meat and bones of the poultry, a zigzag circular cutter is often used for cutting, especially for cutting and separating meat and legs of the poultry, in the prior art, the cutter for cutting the poultry is of a common zigzag structure, when the meat and bones of the poultry are cut, the skin and meat parts and the bone parts are generally cut into the same knife edge, which easily causes skin and meat cutting openings to be tidy, but the bone parts are subjected to more bone fragments, and more broken meat, broken bones and other waste residues are adhered on the cutter, so that the quality of the products is uncontrollable, the overall production efficiency is influenced, and certain foods and the like also have to be removed in the processing process. The Chinese patent application number 201820169929.0 discloses a bone-meat separator which comprises a machine body, a round hole, a motor, a spiral meat mincing rod, a discharging square hole, a first round tube, a strip-shaped hole, a strip-shaped scraper, a round hole roller, a sleeve, a trapezoid block, a round plate, a Y-shaped supporting rod, a round rod, a trapezoid through hole, a connecting bearing and a second round tube, wherein the spiral meat mincing rod is arranged in the round hole, the round hole is formed in one side surface of the machine body, the top of the machine body is provided with the discharging square hole, the bottom of the discharging square hole is communicated with the round hole, one end of the spiral meat mincing rod is rotatably connected with the bearing assembled in the round hole, the second round tube is fixedly arranged at a port of the round hole, and one end of the second round tube is rotatably connected with the first round tube through the connecting bearing. However, the bone-meat separator can only separate bones and meat, can not automatically separate tendons in meat, so that the separation efficiency is low, the separating knife and the knife shaft are cast by adopting integrated molding, if one part of the separating knife and the knife shaft are damaged, the separating knife and the knife shaft are damaged integrally, the whole separating knife and the knife shaft are replaced integrally, and the maintenance cost is increased.
