In the production process of die-cutting printed products, the die-cutting device cuts a plurality of printed product units on the paperboard according to the shape of the designed printed products (such as packaging paper boxes), and in order to accelerate the die-cutting speed of the printed products, the current die-cutting device adopts an incomplete cutting mode, namely, after die-cutting, all the printed product units are adhered with rim charge through fine toothed blocks. Therefore, after the die cutting of the printed matter, a waste removing process is also needed, namely, each printed matter unit and the rim charge are torn through fine toothed blocks, and each printed matter unit is separated from the rim charge.
In order to separate printed product units from rim charge, a die-cut paper box removing device in the prior art comprises a plurality of upper box removing dies and a plurality of lower box removing dies, the outline shapes of the upper box removing dies and the lower box removing dies are completely consistent with those of the upper die cutting dies and the lower die cutting dies of the original die cutting device, and when the upper box removing dies and the lower box removing dies are matched, each paper box unit and rim charge are torn through fine toothed blocks, so that each paper box unit and rim charge are separated. The paper box unit is equivalent to a printed matter unit, and the automatic removal of the printed matter rim charge is realized by the die-cut paper box removing device, but for printed matter units with different shapes, an upper box removing die and a lower box removing die are required to be replaced, namely, the upper box removing die and the lower box removing die are required to be redesigned, and the cost of removing the rim charge of the printed matter is obviously increased due to the fact that the upper box removing die and the lower box removing die are relatively expensive. Therefore, the die-cutting paper box removing device cannot be popularized and applied because of the lack of universality and high cost.
In order to solve the problem that the upper box-withdrawing die and the lower box-withdrawing die need to be frequently replaced, in the Chinese patent of patent number CN201410287945.6, a box-withdrawing device of a die-cutting paper box is disclosed, and comprises a frame, a supporting frame, a first lifting frame, a second lifting frame, a first lifting mechanism, a second lifting mechanism, a die-cutting paper board feeding mechanism, a finished product withdrawing mechanism, at least two first sliding grooves, a plurality of second sliding grooves, at least two third sliding grooves, a plurality of fourth sliding grooves, a plurality of elastic ejector rods, a plurality of rim charge ejector rods and a plurality of fixed ejector rods, wherein a plurality of sliding blocks and locking mechanisms for locking the sliding blocks are arranged in each of the first sliding grooves, the second sliding grooves, the third sliding grooves and the fourth sliding grooves; the support frame, the first lifting mechanism and the second lifting mechanism are all arranged on the frame, the first lifting frame is connected with the power output end of the first lifting mechanism and is positioned above the support frame, and the second lifting frame is connected with the power output end of the second lifting mechanism and is positioned below the support frame; each first chute is fixedly arranged on the first lifting frame and extends along the first direction; each second chute is arranged on the first chute through a sliding block in the first chute, and extends along the second direction; each third chute is fixedly arranged on the second lifting frame and extends along the first direction; each fourth chute is arranged on the third chute through a sliding block in the third chute, and extends along the second direction; the upper ends of the elastic ejector rods and the rim charge ejector rods are respectively arranged on corresponding sliding blocks in the second sliding grooves, and a plurality of rim charge ejector rods are arranged on the periphery of each elastic ejector rod; the lower ends of the fixed ejector rods are respectively arranged on corresponding sliding blocks in the fourth sliding grooves, and the positions of the fixed ejector rods correspond to the positions of the elastic ejector rods one by one; the support frame is provided with a plurality of through holes for each fixed ejector rod to pass through. In the invention, the box is withdrawn by adopting a mode of matching the elastic ejector rod, the fixed ejector rod and the rim charge ejector rod, and the elastic ejector rod always presses the paper box unit downwards on the fixed ejector rod in the box withdrawing process, so that the whole stack of paper box units cannot be loosened, the whole stack (multiple sheets) of die-cut paper boards are withdrawn, and the production efficiency is greatly improved; the positions of the elastic ejector rods, the rim charge ejector rods and the fixed ejector rods can be adjusted at will, so that no matter how the paper box units on the die-cut paper board are distributed, the elastic ejector rods and the fixed ejector rods can be used for ejecting corresponding paper box units, and as the positions of the rim charge ejector rods can be adjusted at will, the plurality of rim charge ejector rods can form the approximate outline of the paper box units with any shape, the die-cut paper box can be suitable for the box withdrawal of the paper box units with any shape, and for the paper box units with different shapes, only the positions of the elastic ejector rods, the fixed ejector rods and the rim charge ejector rods and the combination thereof are required to be adjusted, and a box withdrawal die is not required to be replaced like the prior art, so that the box withdrawal cost is greatly reduced, the die-cut paper box withdrawal device has higher universality and can be widely popularized and applied.
However, the two related paper cutting boxes are taken off the box device, which adopts the mode of pressing down the rim charge downwards, putting down the printed product unit from top to bottom, and then ejecting the printed product unit upwards, the mode requires that the paper cutting paper boards are required to be fixed in position and cannot be continuously conveyed, the rim charge removing device similar to the box taking-off device at present cannot be produced on line and cannot be directly connected with the paper cutting device, after the paper cutting paper boards are stacked, the rim charge removing device is additionally used for removing the rim charge, a plurality of intermediate links such as stacking, counting, finished product switching, multi-stage conveying and the like are generated, the equipment cost is increased, and the production efficiency is reduced.
