The user first transports the carton through the conveyor. After the carton enters the inner cavity of the processing box, the first DC motor drives the rotating column to rotate, so that the cutter disc drives the cutter to rotate. After the carton reaches between the rotating column and the right rubber roller, the cutter punches the surface of the carton to cut grooves on the carton. The number of grooves can be adjusted by the number of installed cutters, and the spacing of the grooves can be adjusted by changing the speed of the first DC motor. Second, during the grooving process, the user can adjust the distance between the two cutter discs, so that the grooving position can be adjusted. During the adjustment, the user turns on the first stepper motor, which drives the one-way threaded rod to rotate. During the rotation of the one-way threaded rod, the thread sleeve is pushed forward through the surface thread of the one-way threaded rod, so that the movable frame slides on the surface of the support rod. During the sliding process, the movable frame drives the cutter disc to slide through the rotating disc, so that the cutter disc can drive the cutting knife to adjust its position. 3. The carton after slotting continues to be transported to the left and reaches the top of the left rubber roller. At this time, the second DC motor drives the driving rod to rotate. The driving rod drives the sliding sleeve to rotate during the rotation. At the same time, under the meshing transmission of the gears and teeth, the rotating sleeve rotates on the surface of the moving disk. The rotating sleeve drives the knife holder and the punching knife to rotate during the rotation. The punching knife contacts the surface of the rubber roller when it is vertically downward and contacts the carton to make a hole. The scraps cut from the carton will enter the inner cavity of the punching knife and squeeze the stripping block. After the punching knife is out of contact with the rubber roller, the first spring rebounds and pushes the stripping block to reset, so that the scraps are pushed out of the inner cavity of the punching knife. Fourth, before drilling a hole, the user can adjust the spacing between the two movable disks to adjust the drilling position. During the adjustment, the user turns on the second stepper motor to drive the bidirectional threaded rod to rotate. Under the action of the threaded advancement on the surface of the bidirectional threaded rod, the two movable disks respectively drive the two rotating sleeves on their surfaces to move toward or away from each other for adjustment. When the punching knife needs to be replaced, the user uses the second stepper motor and the bidirectional threaded rod to simultaneously move the two movable disks to the front and rear sides of the inner cavity of the processing box, so that the wedge-shaped top block is inserted into the inner cavity of the wedge-shaped through hole. Under the extrusion action of the wedge-shaped top block and the inclined surface of the wedge-shaped through hole, the two limit clamps move away from each other to release the lock on the punching knife. 5. After the carton is cut and punched, it reaches the top of the conveyor on the left. With the cooperation of the pressing wheel and the pressing block, the carton can be indented.

During the rotation of the one-way threaded rod (45), the threaded sleeve (46) is pushed forward through the surface thread of the one-way threaded rod (45), thereby causing the movable frame (41) to slide on the surface of the support rod (43). During the sliding process, the movable frame (41) drives the cutter disc (32) to slide through the rotating disc (42), thereby causing the cutter disc (32) to drive the cutting knife (33) to adjust its position. The carton after the slotting continues to be transported to the left and reaches the top of the left rubber roller (38). At this time, the second DC motor (518) drives the driving rod (517) to rotate. The driving rod (517) drives the sliding sleeve (515) to rotate during the rotation. At the same time, under the meshing transmission action of the gear (516) and the teeth (514), the rotating sleeve (513) rotates on the surface of the moving plate (512). The rotating sleeve (513) drives the knife seat (52 0) and the punching knife (521) rotate, the punching knife (521) contacts the surface of the rubber roller (38) when it is vertically downward, and contacts and punches a hole in the carton, and the scraps cut from the carton enter the inner cavity of the punching knife (521) and squeeze the material return block (522), after the punching knife (521) is out of contact with the rubber roller (38), the first spring (523) rebounds and pushes the material return block (522) to reset, so that the scraps are pushed out of the inner cavity of the punching knife (521); Before drilling a hole, the user can adjust the spacing between the two movable disks (512) to adjust the drilling position. During the adjustment, the user turns on the second stepper motor (510) to drive the bidirectional threaded rod (511) to rotate. Under the action of the threaded advancement of the bidirectional threaded rod (511), the two movable disks (512) respectively drive the two rotating sleeves (513) on their surfaces to move toward or away from each other for adjustment. When the punching knife (521) needs to be replaced, the user uses the second stepper motor (510) and the bidirectional threaded rod (511) to simultaneously move the two movable disks (512) to the front and rear sides of the inner cavity of the processing box (1), so that the wedge-shaped top block (525) is inserted into the inner cavity of the wedge-shaped through hole (526). Under the action of the inclined surfaces of the wedge-shaped top block (525) and the wedge-shaped through hole (526), ​​the two limit clamps (524) move away from each other, thereby releasing the lock on the punching knife (521). Finally, after the grooving and hole-cutting are completed, the carton arrives at the top of the left conveyor (2), and the carton is indented by the cooperation of the pressing wheel (65) and the pressing block (64).
