Cutter grinding device for food processing

The invention discloses a food processing cutter polishing device which comprises two sets of parallel metal substrates, and the two ends of the top of one set of metal substrates are each provided with a first fixed square mounting bin and a first transverse moving square bin; and a second fixed square mounting bin and a second transverse moving square bin are arranged at the two ends of the top of the other group of metal substrates. Through mutual cooperation of a first pneumatic cylinder, a sliding mechanism and two cutter fixing mechanisms, the device can stably clamp cutters with different lengths, clamping and grinding are guaranteed, and meanwhile the applicability of the device is improved to the maximum extent; by the adoption of the mode of the grinding mechanism transverse moving structure and the grinding mechanism fine adjustment assembly, reciprocating, independent and automatic grinding of the two sides of a sharp opening and grinding of the sharp opening on the side edge are achieved, the abr
