The exhaust section temperature needs to be lower than the thermal decomposition temperature of the material, usually 10 to 30°C lower than the metering section, in order to suppress the thermal degradation reaction.
The cleaning agent, sprayed under high pressure, can penetrate deep into the micropores of the ink, disrupting the adhesion between the ink and the printing roller, thus creating conditions for subsequent peeling.
Regularly cleaning the vent holes and the screw's reverse thread edge can prevent carbon deposits from clogging the channels and ensure smooth exhaust.
High-speed computer gravure printing machines, as core equipment in flexible packaging, labeling, and high-end printing fields, are widely used for high-precision color printing on diverse substrates such as roll plastic film, aluminum foil, and paper rol
In the operation of a high-speed computer gravure printing machine, controlling the viscosity and flowability of the ink is a core aspect of ensuring printing quality.
The winding and unwinding mechanism of a rewinder involves the rotational motion of large-diameter rollers, and its lubrication focuses on reducing impact friction during the start-up and braking phases.
