Research On The Design And Dynamic Characteristics Of The Drive System Of The Integrated Binding Machine

Recently made in China 2025 strategy was proposed,and intelligent applications have gradually become popular,packaging equipment industry has had a significant impact.Automatic equipment gradually replaced the previous manual equipment and semi-automatic equipment.Packaging equipment gradually toward the integrated,intelligent,efficient,long life,low noise direction.At present,the market urgently needs to develop a new type of packing tie mouth equipment.This research group focuses on the market demand and carries out the research and development work of category equipment.For this purpose,this paper mainly does the following work:1.In view of the current research status of packaging equipment at home and abroad,the design concept of "drive function integration,compact structure,convenient transfer and docking" was put forward.Bending,extrusion type tying "process scheme was adopted,the technological process is broken into" together with traction,mouth,the belt,belt cutting,bending,cable tie to finalize the design "six consecutive working procedure,and on this basis components are arranged to work in time,clear action sequence diagram is designed,and parts structure are designed.2.According to the functional requirements of the equipment,the characteristic parameters of the CAM in the main driving parts were designed,checked and verified.The analytical formula of CAM swing Angle error was derived,which provides a theoretical basis for CAM inspection and checking.According to the sequence diagram,the mathematical model and motion equation of each CAM contour are solved,and the dynamic image was drawn.3.The mechanical model of the three degrees of freedom micro-vibration of the transmission parts was established and the multi-degrees of freedom micro-vibration analysis theory was adopted.Taking the forming part as an example,the rotational vibration characteristics in X and Y directions and plane torsion are analyzed.Using Newton’s third law of motion,the differential equation of the vibration of the model is derived for the natural frequency of its vibration The vibration states at different resonant frequencies were analyzed,and the displacement curves of vibration are drawn.A "linear independent vector method" is applied to optimize forced vibrations caused by unbalanced inertial forces.The mathematical model of vibration system was established and the specific value of optimization parameters is solved.The vibration of the spindle assembly is optimized using a dynamic balancing method.The vector equation sum is zero is applied to solve the magnitude and direction of the mass moment.ANSYS Workbench software is adoptail for modal analysis and harmonious response analysis of complex and important parts.The results show that its dynamic performance is outstanding,and its anti-vibration performance is excellent.
