摘要

Block cutting machine comprising a structural frame (1, 2, 3, 5) inside which a cutting blade (L) slides like a guillotine, remains elastically elevated and is capable of descending under pressure towards a support plane (4) by means of a lever transmission mechanism, said mechanism comprising at least one lever (12, 13), with fulcrum on an upper transverse element (5) of said frame in an off-center position, and a pin of thrust (9) that acts on said cutting blade (L) and is adjustable in a longitudinal position on a support plate (6), pivoting said plate (6) in a vertical plane with respect to said upper transverse element (5), characterized in that said actuation lever (12, 13) is integrated in rotation with a small shaft (10a) that has at least some first (10) and second (14) cam profiles that cooperate with a part (6a) of said pivoting plate (6).
