The invention discloses an automatic fixed-distance
cutting device for
kraft paper, which relates to the technical field of
kraft paper production, and comprises a
workbench and a centering device, wherein a manual
cutting device is arranged on the top of the
workbench, a placing frame is fixedly installed on the front side of the
workbench, a
servo motor is fixedly installed on the front side of the placing frame, a rotating rod is fixedly installed on the output end of the
servo motor, and a
chain conveyor belt is arranged on the circumferential surface of the rotating rod, wherein the centering device comprises an
extrusion rod, a placing groove, a placing plate, a placing rod, a hollow rod, a guide groove, a guide rod and a centering plate, wherein the hollow rod moves in a direction close to the
kraft paper to drive the centering plate to move, and the movement of the centering plate centers the kraft paper on the top of the
chain conveyor belt, and the movement of the centering plate can accurately position the kraft paper in the center of the
chain conveyor belt, thereby reducing the
cutting error caused by the deviation of the kraft paper, thereby improving the cutting accuracy of the kraft paper.
