Description

Technical Field

[0001] The utility model relates to the technical field of creasing and slotting machines, in particular to a creasing and slotting machine for a cardboard printing machine. Background Art

[0002] Cartons are generally assembled from corrugated paper after crimping and slotting. The crimping part and slotting part of the existing corrugated board printing machine are integrated. After searching, the Chinese patent with publication number CN109551816B discloses a crimping and slotting system of a corrugated board printing machine, which includes a crimping machine and a slotting machine. The slotting machine is located at the discharge end of the crimping machine. The crimping machine includes a crimping machine frame, a crimping paper feeding roller, a crimping paper discharging roller, a plurality of upper crimping wheel groups, a plurality of lower crimping wheel groups used in conjunction with the upper crimping wheel groups, and a plurality of crimping wheel group drive motors. The slotting machine includes A slotting machine frame, a slotting paper feeding clamping roller, a plurality of slotting wheel groups, a plurality of paper supporting wheel groups used in conjunction with the slotting wheel groups, a slotting machine driving motor and a plurality of slotting wheel group adjusting motors. When in use, the corrugated cardboard is sequentially pressed by the creasing paper feeding clamping roller, the first pre-pressing wheel, the second pre-pressing wheel and the creasing wheel, and then output from the creasing paper output clamping roller. The spacing between the two first pre-pressing wheels, the two second pre-pressing wheels and the two creasing wheels between the upper creasing wheel group and the lower creasing wheel group gradually decreases. The cardboard is pre-pressed twice step by step by the first pre-pressing wheel and the second pre-pressing wheel, and then passes through the creasing wheel. The cardboard enters the slotting machine for slotting after the pressing line is completed. The cardboard enters from the slotting paper feeding roller. The cardboard passes through the first slotting knife installation plate, the edge material cutting knife installation plate and the other slotting knife installation plate in turn. The slotting knives on the two slotting knife installation plates slot the front and back ends of the cardboard respectively. The edge material cut by the first slotting knife is cut into multiple sections by a group of cutting knives on the edge material cutting knife installation plate, so that the edge material is discharged from the gap between the two slotting knife installation plates. The cardboard is withdrawn to avoid the cut edge material from being blocked on the tray. In the cutting groove of the paper wheel, although this method cuts off the scraps to avoid clogging, this grooving method and the problem of shredding the scraps consume a lot of energy, and the shredded paper scraps are easily sucked into the pressing process as the cardboard is pressed, which easily hinders the pressing operation of the pressing mechanism. Therefore, a grooving structure is designed that can discharge the scraps without shredding the scraps cut by the grooving, which solves the problem of the scraps being sucked into the pressing process due to shredding and affecting the pressing operation, and improves the stability of the pressing grooving to improve the cardboard printing machine.
