Broad spray head for printing machine cylinder or roller cleaning system covers entire width of cylinder and has mixer at center point creating homogenous mix of cleaning fluid and air

摘要

Dosing pumps (3) draw fluid from separate reservoirs (1,2) and feed it through pressure lines (4) and non-return valves (6) to an intermediate line (5). Air is fed through a valve (7) from a high-pressure source (10) to a first measurement and control module (8) and a non-return valve (9). The air joins the fluid in the intermediate line and passes to a fluid-air mixer with a nozzle (13-15). A homogenous mix of fluid and air is fed (11) to the center of a broad spray head (12) covering the entire width of the cylinder.
