The spacing of top center position is L1, and the spacing of two panels blade tip center position is L2, L1≤L2, L1 in another set of blades
=0.5D；Knife rest guide rod drives turning block to rotate under space cam effect simultaneously, so that dress knife bar upset；
Step 4: after the charging tray for being placed with broccoli reaches the underface of adjustment mechanism, conveyer belt stop motion；3rd driving group
Part driving cross guide rail moves downward, so as to promote dress knife bar to be slided diagonally downward along knife bar slide rail, four blade cleavages
Broccoli immediately below adjustment mechanism；
Step 5: the second drive component driving space cam rotates so that four rollers arrive separately at the first sky on space cam
Between convex arc, second space convex arc, the 3rd space convex arc, the 4th space convex arc farthest away from space cam axis；Now, four knives
Piece is displaced outwardly respectively；Meanwhile the 3rd drive component driving cross guide rail move upwards, the second drive component driving space cam
Rotate so that four rollers arrive separately at the first space concave arc on space cam, second space concave arc, the 3rd space concave arc, the
Four space concave arcs are at space cam axis；
Step 6: repeat step two, three, four and five is until complete the stripping and slicing of all broccoli to be cut；
Step 7: bouquet and stem after stripping and slicing are sieved with sieve.
