[0022] Please see Figures 1-4In this utility model, an adjustable printing squeegee for water-based ink printing includes a first blade 1. A second blade 2 is bolted to the outer surface of the first blade 1. Three first threaded cylinders 3 are bolted to the inner top wall of the first blade 1. A threaded rod 4 is threaded to the inner side wall of each first threaded cylinder 3. A second threaded cylinder 5 is threaded to the outer surface of each first threaded rod 4. A partition plate 6 is bolted to the bottom surface of each second threaded cylinder 5. A turbine 7 is bolted to the outer surface of each threaded rod 4. Two support plates 8 are bolted to the outer surface of the second blade 2. Bearings 9 are fixedly embedded on the close sides of the support plates 8. The inner rings of the two bearings 9 are fixedly connected to a worm gear 10. The worm gear 10 meshes with each turbine 7. The outer surfaces of the first blade 1 and the second blade 2 are slidably connected to a rubber strip 12. Through the cooperation of the first threaded cylinder 3, the threaded rod 4, the second threaded cylinder 5, the turbine 7 and the worm gear 10, rotating the worm gear 10 can adjust the distance between the first threaded cylinder 3 and the second threaded cylinder 5, thereby changing the position of the partition plate 6. The partition plate 6 can directly contact the rubber strip 12, making it easy to adjust the rubber strip 12 to be parallel to the printing roller.

[0023] A throttle 11 is fixedly connected to the right side of the worm gear 10. A turning arrow 15 is provided on the outer surface of one of the support plates 8. A scale 13 is provided on the back of the first blade 1. A position arrow 14 is provided on the upper surface of the partition 6. By setting the turning arrow 15 and the scale 13, the position of the partition 6 can be quickly known, which facilitates precise adjustment of the position of the partition 6.

[0024] Both the outer surfaces of the first cutting edge 1 and the second cutting edge 2 are fixedly connected to sliders 16. The outer surfaces of each slider 16 are slidably connected to a tool holder 17. The outer surfaces of the tool holder 17 are slidably connected to two fixing clips 18. The inner sidewall of each fixing clip 18 is fixedly connected to a rubber pad. The upper surface of each fixing clip 18 is provided with a threaded hole 19. The inner wall of each threaded hole 19 is threaded with a fastening bolt 20. By setting sliders 16, it is easy to install them on the tool holder 17 and the position of sliders 16 can be adjusted. Through the cooperation of fixing clips 18 and fastening bolts 20, sliders 16 are fixed on the tool holder 17 to prevent slippage.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, turn the handle 11 to rotate the worm gear 10, which in turn drives the turbine 7 to rotate. The turbine 7 drives the threaded rod 4 to rotate, which increases or decreases the distance between the first threaded cylinder 3 and the second threaded cylinder 5, thereby changing the position of the partition 6. Place the rubber strip 12 between the first blade 1 and the second blade 2, and rotate the bolt to fix the rubber strip 12 tightly against the partition 6. Slide the slider 16 into the blade holder 17 and adjust it to a suitable position. Rotate the fastening bolt 20 to fix the position of the first blade 1 and the second blade 2, thus completing the installation of the scraper.
