Automated capping devices have emerged in recent years. Initially, their structure was very simple, consisting of a base and a rubber disc. People only needed to use them for capping. However, as time went by, people encountered many problems during long-term use. For instance, the automated capping device was prone to damage the lid and objects during the capping operation. There are certain restrictions on the size of objects that need to be covered, so on the basis of these issues, people have been constantly innovating and improving.

The existing capping device has a relatively simple overall structure and cannot guarantee that the lid will not be damaged during clamping. It does not have the ability to cap objects of any size under normal circumstances, thus making it impossible to use the equipment well. Under long-term capping, the objects that need to be capped will also be damaged, directly affecting the continuous stability of the equipment. It cannot well meet people's usage demands. In response to the above situation, technological innovation is carried out on the basis of the existing capping device.
