The main reason for the wide-width satellite flexo press roll
Wide-format satellite flexo presses are increasingly favored by industry professionals due to their simple control system, accurate overprinting and high production efficiency. However, in daily production, some small problems often cause headaches for operators. For example, plate roll beating is one of the common problems. If the plate roller jumps during the operation of the wide-format satellite flexo press, the printing quality is greatly reduced. An impact is also generated at the contact of the plate roller head with the bearing, thereby reducing the service life of the bearing. Therefore, effectively solving the plate roll and improving the printing quality is an important task that needs to be solved. The main reason for the roll of the roll During the operation of the wide-format satellite flexo press, there are many reasons for the plate roll beating. In summary, there are four main aspects as follows. (1) The quality of the plate roll itself is not uniform, which will damage the running balance of the plate roller and cause the beating. (2) The roll core of the plate is thicker and the plate roll is heavier. A certain degree of eccentricity or bending occurs during the operation, which has a great influence on the dynamic balance of the plate roll and also causes the jump. (3) During the process of installing the sleeve, since the sleeve and the plate roller are in a cantilever state, the plate roller is prone to flexural deformation, which is an important factor affecting the plate roller jump. (4) The plate roller itself is unbalanced during the movement.
