[0028] The drawings in the specification are structural schematic diagrams, and the specific size can be adjusted according to actual use.

[0029] Working principle: when in use, the device is installed through the mounting plate 9, so that the waste generated in the corrugated paper processing is input into the edge collecting hopper 3.

[0030] The negative pressure assembly 11 is started, the negative pressure assembly 11 generates negative pressure inside the collecting box 5, provides suction for the top opening of the edge trimming hopper 3 in turn through the air holes on the inclined filter screen plate 12, the crushing assembly 7 and the bellows 8, the waste cut off by trimming is sucked into the bellows 8 and crushed downward through the crushing assembly 7, the purpose of crushing is to crush the excess part in strip shape into small pieces, so as to avoid occupying the space of the waste cylinder 4 and save space.

[0031] The crushed waste directly falls on the inclined filter screen plate 12, the inclined filter screen plate 12 only conducts air flow, so that the waste is hindered and slides to the box door 16 and is accumulated, and the height of the waste in the collecting box 5 is continuously increased due to continuous accumulation.

[0032] When the air hole of the inclined filter screen plate 12 provided with the airflow sensor 13 is submerged by the waste, at this time, the airflow sensor 13 outputs a signal, so that the telescopic shaft of the air cylinder 10 is elongated, thereby driving the pressing plate 14 to descend.

[0033] The descent of the pressing plate 14 pushes the waste above the box door 16, so as to exert a downward pressure on the box door 16, the box door 16 is provided with a torsional spring at the rotating connection, so that the pushing of the pressing plate 14 can open the box door 16, thereby pushing the waste in the collecting box 5 to fall into the waste cylinder 4 for collection.

[0034] The telescopic shaft of the air cylinder 10 is moved upward, thereby driving the pressing plate 14 to move upward, the movable frame 15 moves outward under the restoring action of the spring 18, until the box door 16 is reset under the action of the torsional spring.

[0035] The movement of the movable frame 15 can drive the scraper 20 to scrape the waste adsorbed on the surface of the inclined filter screen plate 12 by negative pressure, so that the waste is finally pushed out from the position of the box door 16 and falls into the waste cylinder 4.

[0036] When the waste in the collecting box 5 is pushed to the waste cylinder 4, the telescopic shaft of the air cylinder 10 moves upward, thereby driving the pressing plate 14 to move upward, the movable frame 15 gradually moves outward from the pressing plate 14 under the restoring action of the spring 18, until reset, and the box door 16 is reset under the action of the torsional spring.

[0037] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
