The two pulverizing rollers 24 are respectively connected to the driving gear 3 and the driven gear 4. The driving gear 3 is meshed and connected to the driven gear 4. The fixed end of the motor 21 is connected to the pulverizing bin 1, and the output end of the motor 21 is drivingly connected to the pulverizing roller 24 connected to the driving gear 3. Starting the motor 21 can drive the driving gear 3 to rotate, and the driven gear 4 rotates accordingly, so that both of the two shredding rollers 24 rotate, and the waste paper can be pulverized;

[0033] The spraying device includes a water pump 8, a water tank 9, a water pipe 13 and a spray head 14;

[0034] The water pump 8 and the water tank 9 are both connected to the top of the spraying bin 7. The water tank 9 is provided for storing water to facilitate the use of the device. The liquid inlet end of the water pump 8 is connected to the water tank 9.

One end of the water pipe 13 penetrates through the top wall of the spraying bin 7 and is connected to the water outlet end of the water pump 8. A number of spray heads 14 are provided on the water pipe 13. The water pump 8 pumps the water in the water tank 9 into the water pipe 13, and then the water is sprayed onto the paper scraps by the spray heads 14 to wet the paper scraps. Arranging multiple groups of spray heads 14 can accelerate the wetting of the paper scraps.

[0035] Embodiment Three

[0036] As Figures 1-3 shown, a printing waste paper recycling device proposed by the present utility model, compared with Embodiment One, this embodiment also discloses the structures of the pushing mechanism and the compaction device;

[0037] The pushing mechanism includes a first pushing device 19 and a first push plate 20. The fixed end of the first pushing device 19 is connected to the first box body 5, and the telescopic end of the first pushing device 19 is connected to the first push plate 20. The first push plate 20 is slidably connected to the spraying bin 7. By starting the first pushing device 19, the paper scraps in the spraying bin 7 can be pushed into the compaction discharging bin 10.

[0038] The compaction device includes a telescopic device 15, a lower pressing plate 16, a second pushing device 22, a second push plate 23 and a second box body 25.

[0039] The telescopic end of the telescopic device 15 is connected to the lower pressing plate 16, the fixed end of the telescopic device 15 is connected to the compaction discharging bin 10, the lower pressing plate 16 is slidably connected to the compaction discharging bin 10, the second box body 25 is connected to one side of the compaction discharging bin 10, the fixed end of the second pushing device 22 is connected to the second box body 25, the telescopic end of the second pushing device 22 is connected to the second push plate 23, and the second push plate 23 is slidably connected to the compaction discharging bin 10 and the second box body 25. When a large amount of crushed paper scraps accumulate in the compaction discharging bin 10 under the pushing of the pushing mechanism, the water pump 8 is turned off to stop spraying, so that one side of the first push plate 20 enters the compaction discharging bin 10, and the rightmost side of the first push plate 20 is aligned with the leftmost side of the lower pressing plate 16. Then the telescopic device 15 is started to push the lower pressing plate 16 to move downward to squeeze the shredded paper scraps, separating the paper scraps from the water, squeezing the crushed paper scraps, reducing the space occupancy rate of the crushed paper scraps. Finally, the second pushing device 22 is started and the closing door 11 is opened to push out the paper scraps, facilitating the discharging of the paper scraps.

[0040] In this embodiment, the bottoms of the first push plate 20 and the second push plate 23 are both conical, and the lowermost ends of the first push plate 20 and the second push plate 23 are closely attached to the upper surface of the filter plate 17. The wetted paper scraps are easily adsorbed on the filter plate 17. By setting the bottom cross-sections of the first push plate 20 and the second push plate 23 as triangles, the first push plate 20 and the second push plate 23 can scrape the remaining paper scraps on the filter plate 17 while moving, preventing the filter holes on the filter plate 17 from being blocked and affecting the water flow.

[0041] In an alternative embodiment, the telescopic device 15, the first pushing device 19 and the second pushing device 22 can be selected but are not limited to hydraulic cylinders or air cylinders.

[0042] It should be noted that both the first box body 5 and the second box body 25 are hermetically arranged. The first pushing device 19 and the second pushing device 22 respectively penetrate through the first box body 5 and the second box body 25, and are hermetically treated at the penetration points to prevent water from flowing into the first box body 5 and the second box body 25 and damaging the first pushing device 19 and the second pushing device 22.

[0043] In summary, when processing printed waste paper, first put the waste paper into the feed hopper 2, then start the motor 21. The motor 21 drives the driving gear 3 to rotate, and the driving gear 3 drives the driven gear 4 to rotate, so that the two crushing rollers 24 rotate accordingly to crush the waste paper. The crushed waste paper falls to the bottom of the crushing chamber 1. Then start the fan 12 to blow the paper scraps into the spraying chamber 7. Next, start the water pump 8 to let the water in the water tank 9 flow into the water pipe 13 and be sprayed out by the nozzle 14 to wet the paper scraps in the spraying chamber 7. Then start the first pushing device 19 to push the first push plate 20 to scrape up the wet paper scraps at the bottom of the spraying chamber 7 and push them towards the compaction and discharging chamber 10. When the paper scraps in the compaction and discharging chamber 10 accumulate to a certain amount, make the right side of the first push plate 20 flush with the left inner wall of the compaction and discharging chamber 10. Start the telescopic device 15 to lower the position of the lower pressing plate 16 to squeeze the paper scraps. The water in the paper scraps flows through the filter plate 17 and is collected in the water collecting tank 6. Finally, start the second pushing device 22 to drive the second push plate 23 to push out the waste paper in the compaction and discharging chamber 10, which is convenient for discharging the paper scraps and has the effects of preventing the paper scraps from splashing and reducing the space occupancy rate of the crushed paper scraps.
