The invention discloses an improved automatic bamboo shoot slicer. The slicer comprises a rack and a belt conveying mechanism arranged on the upper surface of the rack. Side baffles used for limitingbamboo shoots are arranged at the feeding end on the rack, and baffle micro adjusting mechanisms used for the side baffles are arranged on the rack. A bamboo shoot flexible pressing mechanism and a cutting blade oscillating mechanism used for cutting the bamboo shoots are mounted in the middle of the rack. The bamboo shoot flexible pressing mechanism is located between the cutting blade oscillating mechanism and the side baffles, and a flat pressing mechanism used for preventing stacking of the bamboo shoots is arranged on the side, close to the feeding end, of the bamboo shoot flexible pressing mechanism. According to the improved automatic bamboo shoot slicer, the bamboo shoots can be limited, the bamboo shoot feeding regularity is guaranteed, in addition, the bamboo shoot cutting stability can be further guaranteed, the good appearance shapes of the cut bamboo shoots are well guaranteed, meanwhile, the improved automatic bamboo shoot slicer is high in overall disassembly degree, disassembling operation is greatly facilitated, particularly, the cutter replacing difficulty is greatly reduced, and the time and manpower cost is saved for enterprises.
