Analysis And Design On The Paper Delivery System Of Mould-Cutting Machine

Mould-cutting machine is one of important devices in packing printing industry,the operating efficiency and accuracy of its paper delivery system affects the whole machine a lot. A printing and packing mechanism factory wanted to refit the paper delivery system of the mould-cutting machine from the cable manual delivery to the push pedal to-and-fro delivery.In this article,the delivery system of the MY type mould-cutting machine was discussed for the sake of improving the speed and reducing the shake of the whole machine.The following work was mainly finished:â… The motion analysis and synthesis of the mechanism.The motion analysis of the delivery system was solved through the method of analytic relation,and the displacement,velocity, acceleration of each component in a motion period were obtained.The dimension synthesis was done to definite the parameters of every component for the purpose of reach the given motion pattern and speed.â…¡3-D motion simulation.The linkage model was established by VC and OpenGL,and was romanced and controlled by OpenGL.Adding in the operating area to the interface,the users could change the parameters through it.â…¢The optimization of the mechanism.The speed of roller was given,and it was the same as the rotational speed of the crank,when roller's angle speed increased,the line speed of roller increased with it.Through changing the length of rods,the speed of paper-push pedal had the same line speed with the roller when the paper reached the roller.â…£The balance of the mechanism.The mechanism was balanced through the method of linear independent vector.Complete balance didn't accord with the practical situation,part balance was accepted.A rod was selected to add the balancing weight and the weight was optimized,the balancing result was compared and analyzed.â…¤The strength check of every component.After the mechanism's optimization was solved, the rods' dimension changed.The slender rods were prone to deform,the dynamic static analysis was solved,the pair counterforce was obtained and the strength check of the rods were done.
