[0036] The working principle of the above embodiment is as follows: When the printing machine starts to work, the printing roller rotates between the shaft seats 1, driving the ink for printing. At this time, under the action of the spring 6, the ink scraping plate 4 closely adheres to the surface of the printing roller. As the printing roller rotates, the excess ink is scraped off by the ink scraping plate 4. The scraped ink flows into the collection box 3 along the inclined surface at the left top end of the collection box 3. The filter screen 7 in the collection box 3 filters the ink, separating impurities and pure ink. The pure ink can be further recycled, while the impurities are retained above the filter screen 7. To keep the inside of the collection box 3 clean and avoid ink accumulation, the motor drives the threaded rod 13 to rotate, driving the scraping plate 8 to move linearly in the collection box 3, pushing the ink at the bottom towards the waste discharge pipe 9. Finally, the waste ink is discharged through the waste discharge pipe 9 and can be collected and processed by the ink collection tank 10 threadedly connected to the bottom end of the waste discharge pipe 9.
