Abstract

The invention provides a vibration isolation device for a guide roller of a printing press and a design method, including a local resonance unit group and a cross-shaped trampoline. The cross-shaped trampoline includes a cross-shaped perforated plate and a fan-shaped column, and the fan-shaped column is evenly arranged and fixed on the cross On the outside of the perforated plate, the local resonance units are evenly distributed between the inner cavity of the vibration isolation device and the cross-shaped perforated plate, and the outer side of the fan-shaped column is fixed to the outer cavity of the vibration isolation device. The invention mainly aims to isolate the vibration fundamental frequency of the guide roller of the printing press accurately. First, by adjusting the size of the local resonance unit and the size of the material parameters, it corresponds to the different fundamental frequency peaks of the guide roller of different high-end printing presses; secondly, by designing a cross-shaped trampoline The structure is mainly aimed at the existence of cross-shaped holes, so that each fan-shaped column is rooted on a softer base, and the resonance effect of the fan-shaped column is enhanced, thereby broadening the vibration suppression frequency, and by adjusting the size parameters of the cross-shaped hole and the fan-shaped column size, to flexibly adjust the vibration suppression frequency.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction of rotor shafting systems, and relates to a high-end printing press guide roller vibration isolation device and a design method. Background technique [0002] Shafting system is an indispensable and important component in power plant system, and it is widely used. As a rotor shafting system, the guide roller runs through the whole process of the feeding system of a high-end printing equipment from the start of the unwinding to the end of the winding, and it is also an important criterion for evaluating the quality of a printing press. [0003] When the printing press is running at a high speed, the processing materials, processing accuracy and poor connection of the guide rollers, fulcrums, wall panels and various components will cause vibration of each component, which will lead to wrinkles, lateral drift and Fractures and other phenomena, thereby reducing the accuracy of overprintin...
