[0042] When working, when the rotary screen 2 works, the servo motor 325 drives the two housings 31 away from each other through the connection of the lead screw 326 and the sliding block 323, and the rotary screen 2 is not wrapped, which avoids the interference of the rotary screen 2 printing process. When the rotary screen 2 is wrapped and cleaned, the two housings 31 are close to each other and wrap the rotary screen 2. First, the electrostatic generator 38 makes the magnetic plate 37, the block 36 and the rotary screen 2 adopt static electricity, so as to adsorb the thread, lint and dust on the rotary screen 2, so as to achieve the cleaning purpose. At the same time, the fan 334 extracts the air between the two housings 31 through the negative pressure pipe 332 and the feeding pipe 331, which is more convenient for the adsorption of light impurities.

After cleaning, the washing waste liquid is discharged from the feeding pipe 331 to the collection barrel for collection. Then the fan 334 extracts the air between the two housings 31 again, and the air flow dries the washed rotary screen 2. If the washing waste liquid enters the negative pressure pipe 332, it will stay at the curved position of the negative pressure pipe 332, and the sealing plug 337 will be pressed down by gravity, and the sealing plug 337 will be stretched by the connecting plate 338 to stretch the spring rod two 339.
