The spring 109 is located between the limit block and the bottom inner wall of the housing 106. The knife holder 110 is connected to the bottom end of the slide rod 108 through a connecting block, so that the knife holder 110 can move with the movement of the slide rod 108. The knife holder 110 adopts a quick lock structure that is easy to replace. A blade locking screw hole is opened on the knife holder 110, and the blade locking screw hole passes through the knife holder 110. The pelletizing blade 104 is inserted into the knife holder 110 and can be fastened by a bolt. The pelletizing blade 104 is fixed on the tool holder 110, which is convenient for replacement. The cutting angle of 42° between the tool holder 110 and the circular cutter head seat 102 can make the cut particles more uniform in size. By moving the balance plate 107, the balance plate 107 can push the slide bar 108 and the tool holder 110 to move, thereby realizing the adjustment of the pelletizing blade 104, solving the problem that the four blades must be on the same horizontal plane to be evenly stressed in the prior art, and the prior art is not convenient for pressure adjustment of the four blades, and repeated debugging is required to complete installation and debugging, which affects production efficiency.

[0023] Secondly, the adjusting nut 111 extends into the shell 106 and is rotatably connected to the shell 106; the adjusting screw 112 passes through the adjusting nut 111 and is threadedly connected to the adjusting nut 111.
