Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a cardboard cutting machine, includes frame 1, and a plurality of transfer rollers 2 of setting in the frame that are parallel to each other with frame normal running fit, wherein the one end of foretell a plurality of transfer rollers is stretched out to the frame outside and is connected with fixed first actuating mechanism 3 that sets up in the frame to realize the unified rotation under the drive of first actuating mechanism 3. In this embodiment, the first driving mechanism includes a powered driving motor 31, a conveyor belt 32 (not shown) connected to the output shaft of the driving motor and the protruding ends of the conveyor rollers. And a feeding device 4 opposite to the conveying roller is arranged above one conveying roller 2 which is positioned at the outermost side among the plurality of conveying rollers. In detail, the feeding device comprises a rotating shaft 41 which is positioned above the outermost conveying roller and is horizontally arranged, and two ends of the rotating shaft penetrate through the rack and are rotatably inserted into a supporting mechanism 42 arranged on the rack. And a plurality of squeezing wheels 43 which are axially distributed at equal intervals are arranged on the rotating shaft, and the squeezing wheels have better elastic deformation capacity and can deform to adapt to the thickness of the paperboard when the paperboard is fed in the phase cutting machine.
