[0028] Working principle: When the device is needed, the PLC controller 217 first starts the motor 11, which drives the first rotating shaft 4 to rotate. Then, through the meshing transmission of the first gear 8 and the second gear 9, the second rotating shaft 5 rotates synchronously in the opposite direction, driving the first crushing roller 6 and the second crushing roller 7 to crush the printing waste paper fed into the feed inlet 13. The crushed waste paper falls into the compression box 201. Then, the PLC controller 217 starts the extraction pump 212, which delivers water from the collection box 208 to the U-shaped pipe 209 at a flow rate of 10L / min through the extraction pipe 214 and the discharge pipe 213. The 90° spray angle nozzles 210 evenly distributed on the outer wall of the U-shaped pipe spray and humidify the crushed waste paper, so that the moisture content of the waste paper reaches a suitable state for compression. Then, the PLC controller 217 starts the cylinder 204 with a thrust of 500N, which drives the compression plate 202 to move in the compression box 201, compressing the crushed waste paper into blocks. Next, the solenoid valve 216 is opened by the PLC controller 217, so that the squeezed wastewater and sprayed water are discharged from the inside of the squeezing box 201 through the drain pipe 215, filtered by the filter screen 206, and flow into the collection box 208. At this time, the water in the collection box 208 can be reused for spraying, realizing the reuse of water resources. When the filter screen 206 needs to be cleaned, first rotate the rotating wheel 307 to drive the threaded rod 306 to rotate, so that the moving block 309 slides along the short groove 308. The L-shaped rod 310 drives the slider 302 and the limit rod 303 to disengage from the limit hole 304. Then, pull the pull ring 207 to pull the filter screen 206 out of the U-shaped mounting bracket 205 for cleaning, so as to avoid the filter screen 206 from being blocked and affecting the filtration efficiency. Through the coordinated operation of the above steps, the device realizes the fully automated processing of waste paper crushing, spray humidification, squeezing into blocks and wastewater recycling, effectively saving water resources and improving waste paper processing efficiency.
