The dynamic characteristics of the imprinting roller have a significant impact on the printing quality of the unit type flexographic press.To address the issue of static radial runout being difficult to reflect the dynamic characteristics of the printing press,this study investigates the consistency of dynamic accuracy of the imprinting roller under high-speed production conditions and its correlation with wall panel vibration,providing a reference basis for the structural optimization and status monitoring of the flexographic press.On the basis of analyzing the relationship between the structure,motion parameters,and sampling frequency of the imprinting roller,a data collection and analysis model is established.The correlation analysis method is used to construct a correlation model between dynamic radial runout and wall panel vibration,and dynamic runout and vibration testing research is carried out.Test analysis results:The dynamic radial runout value of the main body of the imprinting roller is about 0.005 to 0.025mm,and the radial runout value will suddenly change 4 times when the imprinting roller rotates for one cycle.Research has shown that the dynamic radial runout of the imprinting roller and the vibration of the wall panel in a unit type flexographic press exhibit non periodic characteristics,and there is a sudden change in the acceleration curve in all directions.The dynamic radial runout of the imprinting roller is strongly positively correlated with the acceleration in the X and Z directions of the supporting wall panel.
