[0030] In particular implementation

[0031] When the screen printing plate needs to be cleaned, first, the screen printing plate is placed horizontally in the fixed frame 8 on the traction rod 7, and then the screen printing plate is fixed on the fixed frame 8 by rotating the threaded rod 9 to prevent the cleaning frame from moving during the later cleaning process.

[0032] After the screen printing plate is fixed, the hydraulic rod 6 is started to drive the traction rod 7 to move towards the end close to the ultrasonic cleaner 2. When the screen printing plate on the fixed frame 8 is completely immersed in the cleaning liquid in the ultrasonic cleaner 2, the hydraulic rod 6 stops working. At this time, the ultrasonic cleaner 2 can be started to work, using its cavitation effect to deeply clean the small pores and gaps of the screen printing plate, removing dry ink and dirt. After the screen printing plate is cleaned by the ultrasonic cleaner 2 for one minute, the hydraulic rod 6 is started to drive the traction rod 7 to move away from the ultrasonic cleaner 2. The screen printing plate is moved out of the ultrasonic cleaner 2 by the hydraulic rod 6. When the fixed frame 8 moves to be parallel to the first inlet 16 on the flushing tank 10, the hydraulic rod 6 stops moving.

[0033] After the fixed frame 8 is parallel to the first inlet 16, the motor 29 on the fixed frame 28 is started to rotate the gear 30. Since the gear 30 is engaged with the toothed rail 35 on the slide rod 27, when the gear 30 rotates, it will drive the slide rod 27 to move in the moving frame 26. The gear 30 rotates to drive the slide rod 27 to move towards the side close to the fixed frame 8. When the slide rod 27 moves, it will drive the flushing tank 10 to move. The auxiliary wheels 5 on the support table 3 assist the movement of the flushing tank 10 during the movement of the flushing tank 10. The auxiliary wheels 5 are fixedly installed on the support table 3 through the two fixed plates 4. When the flushing tank 10 moves, the fixed frame 8 gradually enters the flushing cavity 13 in the flushing tank 10 through the first inlet 16. When the screen printing plate on the fixed frame 8 is completely in the flushing cavity 13, the motor 29 stops driving the gear 30 to rotate. At this time, the high-pressure water pump 19 is started to input the flushing liquid in the water tank 21 into the first water pipe 18, and then into the two groups of high-pressure spray pipes 17 through the first water pipe 18. Then, the flushing liquid is sprayed out through the two groups of high-pressure spray pipes 17. The two groups of high-pressure spray pipes 17 flush the upper and lower surfaces of the screen printing plate. The remaining dirt and cleaning liquid after the ultrasonic cleaner 2 is cleaned are quickly removed by high pressure to ensure the cleanliness of the surface of the screen printing plate.

[0034] At this time, the motor 29 can be started to drive the washing box 10 to reciprocate continuously, improving the cleaning efficiency of the two groups of high-pressure nozzles 17. After pulling out the second plug 24 at the water inlet 25 of the water tank 21, the washing liquid can be added to the water tank 21 through the water inlet 25. When the two groups of high-pressure nozzles 17 are working, waste liquid will be generated in the washing cavity 13. At this time, the water pump 22 in the waste liquid cavity 14 is started. At this time, the water pump 22 draws the waste liquid in the washing cavity 13 into the waste liquid cavity 14 through the first water pipe 18. When the waste liquid in the waste liquid cavity 14 is collected to a certain degree, the first plug 12 at the drain outlet 15 can be pulled out to drain the waste liquid.

[0035] When the screen printing plate on the fixed plate 4 is washed, the motor 29 is started to drive the washing box 10 to move away from the screen printing plate. When the screen printing plate is completely moved out of the washing cavity 13, the hydraulic rod 6 is started to move away from the ultrasonic cleaner 2. When the screen printing plate on the fixed frame 8 is parallel to the second inlet 33 on the drying box 31, the hydraulic rod 6 stops working. At this time, the motor 29 is restarted to drive the washing box 10 to move. When the screen printing plate is completely moved into the drying box 31 on the washing box 10, the fan 32 in the drying box 31 is started to perform the final drying treatment on the screen printing plate. Since the drying box 31 is provided with a water outlet 34 communicating with the washing box 10, when the residual washing liquid on the screen printing plate falls into the drying box 31, the washing liquid is drained into the washing cavity 13 through the water outlet 34. At this time, the water pump 22 can be started to draw the washing liquid in the washing cavity 13 into the waste liquid cavity 14.

[0036] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application. These will not affect the effect and practicability of the present application.
