Optimized Design On The Paper Delivery System To Improve Printing Rate And Feeding Precision

The swing-gripper mechanism of printing machine is a significant structure to feed paper to press cylinder after paper orientation. It's also the one of key parts of printing machine assuring printing rate, precision, quality and process. The mechanism design, manufacture precision and dynamical characteristic of paper delivery system directly affect the printing speed and precision. Designing bases is provided to improve plant's products by analyzing the kinematics characteristic of present delivering frame. Above all, we can improve the printing rate and precision of domestic printing machine by researching the theory of the key structure, which provide designing methods, parameter, excellent basic frame for designing high speed, self-determination property right and good quality printing machine.Firstly, the mechanism of delivering is analyzed and studied. Based on the establishment of the kinematics model of delivering processes with the conjugated cams and joined bars. Three spline number inserting and C programme are applied for optimizing swing-gripper system. The swing-gripper system is re-designed according to optimized datum.Secondly, according the kinematics curve of the cam, analyzed the kinematics of the structure. The reason why the optimized mechanism improve printing speed and precision of printing machine is afforded according to the kinematics curves.Lastly, simulated and analyzed the module by SwolidWorks software. It's useful for finding design error and potential failure early, reducing design cost and cycle by simulating real work circumstance.The Optimized swing-gripper system has been successfully applied in practice.
