The anilox roll is the core of the entire carton press, but it cannot work alone. "Safflower still needs green leaf support", if the anilox roller is safflower, then the green leaf is the rubber roller, and there is a green leaf is a doctor blade system (which is also more expensive). Let's talk about the rubber roller first.
Anilox rollers play the role of ink transfer in printing, so what about rubber rollers?
Rubber rollers mainly play two roles:
1. The angle generated by the contact with the anilox roller forms an "ink fountain", so that the ink flows in it to ensure the supply of ink to the anilox roller.
2. Squeeze, rub and rotate with the anilox roller to rub off the excess ink on the surface of the anilox roller to form a uniform ink layer.
It should be reminded that the double-roller ink transfer system composed of rubber rollers and anilox rollers is mainly used to print large solid and relatively coarse dots. If it is used to print continuous layered versions, the hardness and Control the speed of the vehicle to make adjustments.
The production of the rubber roller is to wrap a layer of rubber on the surface of the seamless steel pipe, and the thickness of the rubber layer should be at least 10mm or more. The wrapped rubber should be resistant to corrosion, high temperature and abrasion.
The rubber roller is usually made into a medium-high (parabolic) shape, and the specific height should be accurately calculated according to the hardness, the thickness of the rubber, the length of the roller, and the diameter of the roller. The formula will not be mentioned, it is very annoying, and the manufacturer can handle it.
Middle and high data is very important, why do you say that?
If the middle and high heights are not correct, the ink transfer of the anilox roller will be uneven, which is what the user should know.
Phenomenon 1: If the middle and high heights are too high, the ink layer on the surface of the anilox roller will be thick at both ends and light in the middle.
Phenomenon 2: If the medium height is too low, the ink layer on the surface of the anilox roller will be light at both ends and thick in the middle.
Both of these phenomena can be repaired by regrinding.
The rubber roller is a roll-shaped product made of metal or other materials as the core and covered with rubber by vulcanization.
