At the same time, the fastener 605 in the fixing plate 602 passes through the arc-shaped slide rail 604 and is fixed to the bracket 601. When it is necessary to adjust the angle of the scraper 603, the fastener 605 can be loosened and the scraper 603 can be rotated along the arc-shaped slide rail 604, so that the fixing plate 602 and the fastener 605 change their positions in the arc-shaped slide rail 604. This allows the scraper 603 to adjust its own angle according to the printing requirements. The fastener 605 consists of bolts and nuts that pass through the arc-shaped slide rail 604.

[0040] Working principle:

[0041] When the mesh cylinder 4 needs to be cleaned, the opening and closing component 8 first drives the cleaning component 7 to unfold, and then the lifting component 2 drives the driving component 3 to rotate upward, so that the driving component 3 moves the mesh cylinder 4 it carries into the working area of ​​the cleaning component 7. Then the opening and closing component 8 closes the cleaning component 7, so that the cleaning component 7 covers the mesh cylinder 4. Then the cleaning pipe 704 inside the cleaning component 7 starts to rinse the mesh cylinder 4. At the same time, the driving component 3 drives the mesh cylinder 4 to rotate, and the wastewater generated during cleaning is discharged through the drain pipe 705 at the bottom.
