The corrugated board 3 is then printed in the printing mechanism 11 by the printing rollers 1115 of each single-color printing mechanism 111, so that a multi-color pattern is printed on the upper surface of the corrugated board 3; finally, the corrugated board 3 is subjected to corner cutting by the corner cutting mechanism 12.
Wherein the suction pump 1117 continuously sucks the ink in the ink reservoir 1111 into the ink relay tank 1112 having a smaller amount of ink, since the ink in the ink relay tank 1112 is smaller in amount, and the viscosity of the ink itself is generally larger, blocking the lower opening of the ink relay tank 1112 with the transfer roller 1114 prevents a large amount of ink from leaking from the ink relay tank 1112.

Waste angle is generated from the angle cutter 12, blown into the pit 21 by the blower 23 and carried away by the conveyor belt in the pit 21. When the waste corner is conveyed to the blower 24 by the conveyor belt, the waste corner is crushed into finer waste corner pieces by the twisted crushing mechanism 2411 on the upper side of the hopper 241, and the waste corner pieces are temporarily stored and accumulated in the hopper 241. When the waste corner materials in the hopper 241 accumulate to a certain amount, the air blower 244 blows air flow to the vortex air duct 243 to form low pressure in the vortex air duct 243 to suck the waste corner materials from the hopper 241 into the chamber 2433 of the vortex air duct 243 through the feeding pipe 242, and meanwhile, as the chamber 2433 is in a disc structure, the air flow forms vortex in the chamber 2433 to be beneficial to dispersing the waste corner materials and preventing the waste corner materials from blocking the vortex air duct 243. Waste corner materials are blown into the air duct 25 through the vortex air duct 243 and conveyed to a compressor outside the production workshop along the air duct 25, in the embodiment, the air duct 25 is in butt joint with a conveying pipeline 2611 of the pre-pressing mechanism 261, the waste corner materials are conveyed into a forming cavity 2613 in the conveying pipeline 2611 through a conveying screw rod 2612, after the waste corner materials in the forming cavity 2613 are accumulated to a certain amount, a lower pressure oil cylinder 2616 drives a lower pressure plate 2615 to press down the waste corner materials in the forming cavity 2613 to form a compressed blank, then a lifting movable baffle 2614 is opened, the conveying screw rod 2612 continues to convey the waste corner materials forwards, the compressed blank is pushed to move forwards by the waste corner materials, then the compressed blank enters a re-pressing mechanism 262, and under the driving of a hydraulic cylinder 2624, an upper pressure seat 2621, a lower pressure seat 2622 and side pressure plates 2623 arranged on the left side and right side of the compressed blank are simultaneously pressed to enable the compressed blank to be subjected to pressure in the upper, lower, left and right directions, the compressed blank is further compressed into a compressed block with smaller volume and compact size, and the compressed block can be compact due to the high compactness, the compressed block size is compact, and the occupied area is reduced.
