The invention discloses a circular cutter leather splitting
machine for manufacturing a flat-bottom athletic shoe. The circular cutter leather splitting
machine comprises a leather splitting
machine body and a supporting rod, wherein the supporting rod is fixedly connected to the upper end of the leather splitting machine body, one end of the supporting rod is fixedly connected with an upper bladegroove column, and an inner groove cavity is formed in the middle of the upper blade groove column; when an adjusting column is adjusted by the circular cutter leather splitting machine, the adjusting amount can be conveniently controlled, and the effect of pressing on the two sides after adjustment is achieved; a cutter
grinding block is arranged on the side wall of a circular blade groove, whena circular blade works, the cutter
grinding block plays a role in
grinding the surface of the circular blade, so that the surface of the circular blade is smooth, and the burr phenomenon caused by the circular blade on leather is greatly reduced; and due to the fact that a
brush is connected to the cutter grinding block, oil injection is directly carried out on the circular blade leather splitting machine, the surface of the circular blade is contacted with the
brush, so that when the circular blade works, the lubricating operation is carried out at the same time. The device is simple in structure, and time-saving and labor-saving are realized.
