[0028] The utility model discloses solved the problem that the existing meat grinder is easy to appear the phenomenon of grinding powder, through setting up wear -resisting spare 2 at the discharge port 11 of meat grinding cylinder, wear -resisting spare 2 adopts high -hardness material, and the wear resistance of the contact surface of meat grinding cylinder and cutter head 6 is enhanced, thereby avoid the occurrence of the phenomenon of grinding powder, prolong the service life of meat grinder. Specifically, wear -resisting spare 2 is made of material with the hardness greater than the hardness of locking nut 7 and meat grinding cylinder body 1, and is arranged on the discharge port 11 of meat grinding cylinder body 1, when the meat grinder works, locking nut 7 and meat grinding cylinder have pressure due to the high -speed rotation of meat grinding screw, and the direct contact between locking nut 7 and meat grinding cylinder body 1 is replaced by wear -resisting spare 2, thereby avoiding the wear of meat grinding cylinder body 1, that is, avoiding the generation of the phenomenon of grinding powder, and simultaneously, since wear -resisting spare 2 is made of high -hardness material, it is ensured that it is not easy to be worn in the use.

[0029] Further, the wear-resistant part 2 is arranged along the circumference of the meat grinding cylinder. Specifically, in the present embodiment, the wear-resistant part 2 is arranged in a ring shape and matches the shape of the discharge port 11. When the cutter head 6 rotates in the meat grinding cylinder, the contact point between the locking nut 7 and the meat grinding cylinder will always fall on the wear-resistant part 2 regardless of the angle, and will not contact the meat grinding cylinder body 1, thereby avoiding the local excessive wear of the wear-resistant part 2. In other embodiments, the wear-resistant part can also be arranged in a plurality of part structures and fixed to the outside of the meat grinding cylinder to contact the locking nut.

[0030] Further, the outside wall of the discharge port 11 is provided with a mounting groove 13 for mounting the wear-resistant part 2, the mounting groove 13 is provided with a positioning block 131, the inner wall of the wear-resistant part 2 is provided with a positioning groove 21 matched with the positioning block 131, and the wear-resistant part 2 is clamped with the positioning block 131 through the positioning groove 21. Specifically, through the clamping mode, the positioning block 131 and the positioning groove 21 form a tight connection, so that the wear-resistant part 2 can be firmly fixed on the meat grinding cylinder body 1 and can remain stable even under the action of the high-speed rotating cutter head 6. When mounting, the user only needs to align the wear-resistant part 2 with the positioning block 131 in the mounting groove 13 and press down, and the mounting can be completed without the need for additional tools or fixing parts.

[0031] Further, the positioning block 131 is a cross-shaped positioning block 131, and the positioning groove 21 is a cross-shaped groove. Through the cross-shaped positioning structure, the tangential force generated by the rotation of the cutter head 6 can be resisted, and the shear resistance is stronger than that of the traditional planar clamping.

[0032] Further, the material of the wear-resistant part 2 is stainless steel, and the wear-resistant part 2 can be any one of SUS304, SUS430 or SUS420. Since frequent friction and collision occur between the locking nut and the wear-resistant part during the operation of the meat grinder, if the hardness of the wear-resistant part is not enough, wear or deformation may occur during these processes. By using a material with a hardness greater than that of the locking nut to make the wear-resistant part, better resistance to wear and damage can be achieved, thereby avoiding the generation of powder phenomenon and improving the service life of the meat grinder.

[0033] SUS304, SUS430 and SUS420 all have good wear resistance and corrosion resistance. SUS304 is a common austenitic stainless steel material with excellent corrosion resistance. It has good corrosion resistance in oxidizing acids, alkaline solutions and most organic acids, as well as in air, water and steam. In addition, it also has good processability, strength and toughness. SUS304 stainless steel is widely used in food processing equipment, including meat grinders. It can resist the corrosion of salt, water and other substances in meat, and maintain the hygiene and performance of the equipment.

[0034] SUS430 is a low-carbon chromium stainless steel with good oxidation resistance and corrosion resistance. It has high yield strength, moderate elongation and hardness, and is suitable for occasions that require certain strength and corrosion resistance.

[0035] SUS420 (including SUS420J1 and SUS420J2, etc.) belongs to martensitic stainless steel and has high hardness and good wear resistance.

[0036] Further, the wear-resistant part 2 is fixed in the mounting groove 13 by sleeve injection molding. The sleeve injection molding method can ensure the close combination between the wear-resistant part 2 and the meat grinder body 1. By placing the wear-resistant part 2 in the injection mold and then injecting the injection material into the injection mold, a meat grinder can be made. Since the meat grinder is made by sleeve injection molding, the injection molded material can tightly fit the gaps of the wear-resistant part 2 during the injection process, further enhancing the firmness of the connection.
