The basic content of plane mechanism force analysis of the cup lid machine is that when the size, mass distribution and movement of the mechanism are known, the constraint reaction force in each moving pair is determined according to the external force acting on each component of the mechanism, and the balance force (or balance moment) should be added to some components in order to maintain the given movement of the active parts.

Because the size and nature of these forces are very important in designing new machines or improving existing ones. For example, in the design of BOPS thermoforming machine, it is necessary to determine the constraint reaction force in each moving pair in order to calculate the strength of the parts, estimate the mechanical efficiency, determine the type of bearing used and study the wear and lubrication of the moving pair. In order to design a new machine or to tap the production potential of existing machines, it is necessary to choose the appropriate motor (or other prime mover) or determine the maximum working resistance that the machine can overcome, which requires the determination of the balancing force of the mechanism.

In the analysis of mechanism force, the force acting on the stacking mechanism is usually divided into two types: known external force and constrained reaction force. Known external force can be divided into driving force and resistance two categories, driving force is to make the active part accelerate the movement of the force, resistance is to make the active part to slow down the movement of the force.
