Research on sealing guide cam of bottle blowing machine based on Creo
In order to improve the stability of fully-automatic rotary bottle blowing machine,the sealing guide cam was optimized. The motion process of the head component was analyzed,and the curve of sealing guide cam was obtained through curve programming according to the combined cycloidal motion law using Creo.The pressure angle analysis and the maximum acceleration verification of the sealing guide cam curve were carried out,and the actual sealing guide cam was verified by experiment.The results show that the average capacity of single cavity of the bottle blowing machine whose sealing guide cam is designed by the combination cycloidal motion law is 2750 bottles/h,and the average noise of the whole machine is 78.90 dB(A);Compared to the bottle blowing machine whose sealing guide cam is designed by the ordinary method,the capacity of single cavity is increased by 22.2％;and the noise of the whole machine is reduced by about 6.18 dB(A).The research provides reference for CAM design in mechanical industry.
