The cutter shaft 30, the first blade 31 and the second blade 32 are integrally formed by injection molding.

The first blade 31 comprises a vertical section 311 connected to the arbor 30. Along the axial direction of the knife shaft 30, the height of the vertical section 311 is greater than that of the second blade 32. In the circumferential direction of the arbor 30, the width of the vertical segment 311 is smaller than the width of the second blade 32. In the radial direction of the knife shaft 30, the length of the vertical section 311 is smaller than that of the second blade 32. By providing different first and second blades 31, 32 on the arbor 30, wherein the height of the vertical section 311 of the first blade 31 is greater and the length of the vertical section 311 of the first blade 31 is smaller; two blades of the dough kneading knife 3 are of asymmetric structures, so that in the dough kneading process, the second blade 32 can press dough to prevent the broken dough from suspending, and the vertical section 311 extrudes the broken dough into dough, so that the dough kneading efficiency is improved.

In the above embodiment, the vertical section 311 includes a top part 312 and a bottom part 313 in sequence along the axial downward direction of the arbor 30. In the radial direction of the arbor 30, the length of the top portion 312 is smaller than the length of the bottom portion 313. So configured, the agglomeration efficiency of the vertical segment 311 is better.

The distance between the second blade 32 and the bottom end of the knife shaft 30 is greater than the distance between the vertical section 311 and the bottom end of the knife shaft 30 and/or the distance between the second blade 32 and the top end of the knife shaft 30 is greater than the distance between the vertical section 311 and the top end of the knife shaft 30.
