Furthermore, the shape of cutting groove is triangle-shaped or circular arc, and the distance of recess minimum and conveying platform plane is 5 millimeters.

Further, a vertical distance scale is arranged on the limiting hole.

Further, the depth of the knife groove is the same as the length of the breakpoint knife.

Furthermore, the cutter grooves are distributed on the cutter roller frame, and the number of the cutter grooves is 4.

Compared with the prior art, the beneficial effects of the utility model are that: the knife roll frame of the breakpoint control device is provided with a plurality of knife grooves, breakpoint knives of different specifications can be placed at the same time, a proper knife head can be selected according to product requirements through the rotary knife roll frame, manual replacement is not needed, time and labor are saved, the breakpoint knives in a non-working state can be stored in the knife grooves, and knife head damage and other potential safety hazards are avoided.
