The output end of the electric push rod 12 is fixedly connected to a U-shaped rod 11. Brushes 10 are fixedly connected to both ends of the U-shaped rod 11. The U-shaped tube 2 is used to transport the clean water in the water tank 7 so that it is sprayed out from the spray head 9. The spray head 9 is used to spray clean water to rinse the screen 4 to be cleaned. The protective cover 1 is used to carry the various components inside it to ensure normal operation. The hollow shell 6 is used to provide a place for the movement of the U-shaped frame.

[0034] Reference Figure 1 and Figure 3The fixed component includes two bottom blocks 13, the bottom block 13 is fixedly connected to the top of the connecting frame 15, the outside of the bottom block 13 is fixedly connected to the U-shaped plate 3, the inside of the bottom block 13 is threadedly connected to the screw rod 22, the bottom block 13 is the basis of the fixed component, and the connecting frame 15 carries various components to ensure that the entire device can operate normally.

[0035] Reference Figure 3 The pushing component includes an electric push rod 20 , the output end of which is fixedly connected to the outside of the connecting column 19 , and the electric push rod 20 is the power source for pushing the connecting column 19 .

[0036] Reference Figure 1 and Figure 3 The top of the screw rod 22 is fixedly connected to a rubber pad 23, and the bottom of the screw rod 22 is fixedly connected to a turntable 21. The screw rod 22 and the rubber pad 23 work together to fix the screen 4 to be cleaned, and the turntable 21 is used to facilitate the rotation of the screw rod 22.

[0037] Reference Figure 3 A slide groove 14 is provided inside the connecting frame 15, and one end of the connecting rod 16 is slidably connected to the inside of the slide groove 14. The slide groove 14 is used for the connecting rod 16 to slide smoothly in the connecting frame 15.

[0038] Reference Figure 1 and Figure 2 The water delivery component includes a water tank 7, which is fixedly connected to the top of the hollow shell 6. A water pump 8 is fixedly connected to the outside of the water tank 7. The output end of the water pump 8 is fixedly connected to the inside of the U-shaped tube 2. The water tank 7 is used to store clean water, and the water pump 8 is used to transport the water in the water tank 7 to the U-shaped tube 2.

[0039] Working principle: Start the electric push rod 20 and push the connecting column 19. Since the connecting column 19 and the connecting frame 15 are rotatably connected through the connecting rod 2 17, the connecting rod 16 is rotatably connected to the bottom wall of the immersion tank 5 and can slide in the chute 14. Under the push of the electric push rod 20, the chute 14 is gradually lifted up, causing the connecting frame 15 to rise, and the screen 4 to be cleaned is placed between the U-shaped plate 3 and the rubber pad 23. By rotating the turntable 21, the rubber pad 23 is brought into contact with the bottom of the screen 4 to be cleaned, thereby fixing the screen 4 to be cleaned. Then start the electric push rod 20, pull the connecting column 19, and the connecting frame 15 begins to descend until the screen 4 to be cleaned is completely immersed in the immersion tank 5. When the ink on the screen gradually softens, the electric push rod 20 is started again to push the connecting column 19 to raise the connecting frame 15, and the screen 4 to be cleaned is pushed out of the immersion tank 5, effectively avoiding the problem of difficulty in cleaning due to hardening of the ink. When the screen 4 to be cleaned is pushed out of the immersion tank 5, the electric push rod 12 is started to place the screen between the two brushes 10. Through the back and forth movement of the electric push rod 12, the brushes 10 thoroughly clean the screen. At the same time, the water pump 8 is started, and clean water flows from the water tank 7 into the U-shaped tube 2 and is sprayed out through the sprinkler head 9, thereby achieving a one-time cleaning of the screen and avoiding the need for secondary cleaning. This improves the cleaning effect and improves work efficiency.
