The traditional Chinese patent with publication number CN109249643A discloses a corrugated board die-cutting machine, which comprises a machine frame and a controller, wherein a fixed die holder, a movable die holder and an executing mechanism are arranged on the machine frame, the movable die holder is matched with a press-cutting plane of the fixed die holder, one side of the movable die holder, which faces the fixed die holder, is provided with cutting dies arranged in the outline shape of a paperboard of a carton, a corrugated board storage frame for placing a corrugated board to be cut is arranged on the fixed die holder, the movable die holder is connected with a transmission arm, the executing mechanism is driven by a driving device, and the transmission arm is driven by the executing mechanism to swing so as to pull the movable die holder to press; the driving device is electrically connected with the controller. Through the action of drive arrangement drive actuating mechanism, actuating mechanism drives the drive arm swing, and then draws movable mould seat and press to the die holder to disposable through cutting die along its range shape cutting out the carton cardboard that needs, very big improvement cutting efficiency.
The above prior art solutions have the following drawbacks: when recycling cutting die and cutting the corrugated paper, because corrugated paper characteristic itself, at the in-process of cutting, produce the wastepaper very easily, and displacement on the cutting die accelerates, raises the piece of corrugated paper easily, makes its wastepaper fly upward in the workshop, is inhaled the lung by the staff easily, causes harm to the staff health.
Disclosure of Invention
The invention aims to provide a die-cutting machine which has the effects of storing paper scraps, preventing the paper scraps from flying in a workshop, creating a healthy environment and reducing harm to the bodies of workers.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a die-cutting machine, includes the frame, set up lower mould in the frame, with lower mould complex cutting die and order about the actuating mechanism of cutting die displacement from top to bottom, the cutting die includes blade holder and blade, the logical groove with corresponding is seted up to the lower mould, still be provided with dust extraction in the frame, dust extraction includes dust absorption box, dust absorption pipeline and air exhauster, the dust absorption box is installed in lower mould bottom and upper end and is seted up the air intake that communicates with leading to the groove, dust absorption pipeline one end and dust absorption box bottom intercommunication, the other end communicates with the air inlet of air exhauster, the gas outlet of air exhauster is connected with the storage piece.
By adopting the technical scheme, after the corrugated paper is placed on the lower die, the cutter holder and the blade are driven to move downwards under the driving action of the driving mechanism, so that the blade can cut the corrugated paper under the matching action of the blade and the through groove, and the cutting work of the corrugated paper is realized; simultaneously the air exhauster work, through the air intake and the logical groove of dust absorption pipeline, dust absorption box, cut the department and produce suction to the corrugated paper, make its blade cut the wastepaper that produces and can store in carrying to storing the piece through dust absorption pipeline and air exhauster, can avoid the piece to fly upward in the workshop to the at utmost, build a better environment, reduce the human body and inhale the wastepaper, the harm that causes the human body helps ensure that the staff's is healthy.
The invention is further configured to: the upper end of the dust collection box is provided with a closed plate which linearly displaces along an air inlet and opens and closes the shielding through groove in the displacement process, the width of the air inlet is not less than twice of the width of the through groove, the air inlet is provided with a plurality of guide rods parallel to the width direction of the air inlet, the closed plate penetrates through the plurality of guide rods, and a compression spring is sleeved outside a section of the guide rods, which is positioned between the side wall of the air inlet, far away from the through groove, and the closed plate; and a linkage piece for driving the closing plate to move away from one side of the through groove is arranged on the cutter holder.
By adopting the technical scheme, when the corrugated paper is cut, the exhaust fan is always in the air exhaust work, when a section of corrugated paper is cut, and the subsequent corrugated paper is conveyed in advance, the air exhaust machine can generate suction to the corrugated paper, so that the normal conveying work of the corrugated paper can be influenced; the guide rod is used for guiding the closed plate, so that the closed plate can only displace along the width direction of the air inlet, and further the compression spring is used for providing a driving force for the closed plate, so that when the corrugated paper is conveyed in advance, the closed plate is blocked below the through groove, the suction force of the exhaust fan to the corrugated paper is isolated, and the normal work of the corrugated paper is not influenced; meanwhile, after the closing plate slides to the lower part of the through groove, a gap is formed between one side of the closing plate, which is opposite to the through groove, and the air inlet, so that the external air can continuously enter the exhaust fan along with the dust collection box, the normal work of the exhaust fan is kept, and the damage of the exhaust fan caused by the idle running of the exhaust fan is avoided;
when the corrugated paper needs to be cut, the closed plate is driven to move away from one side of the through groove through the linkage piece, so that the through groove is communicated with the dust suction box in the process of cutting the corrugated paper by the blade, and an exhaust fan of the dust suction box plays a role in absorbing paper scraps at the corrugated paper in the cutting process; so order to order about the closure plate and anti-reset and move, play to leading to the groove and shelter from or keep away from work, when making it guarantee that the air exhauster carries out absorption work to the piece, do not influence the normal advance transport work of corrugated paper.
