[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Referring to the Chinese patent, the application number is "202120246812.X" for "A lubricating oil canning capping machine". This patent solves the problem that the cover body is a thin plate structure, which is easily damaged or deformed during installation, resulting in leakage of lubricating oil in the later stage. However, there are still defects such as uneven pressure on the circumference of the cap and deformation of the cap under force, which affect the pressing effect and working efficiency. In this regard, we propose a lubricating oil canning capping machine to solve the above problems. Utility Model Content

[0013] Beneficial effects:

[0014] (1) The capping machine for lubricating oil cans can operate through a negative pressure device during pressing, through the cooperation of a lower pressure ring and a conical sealing cover, so that the can cover is subjected to an upward adsorption force, and then the pressing operation is completed as the lower pressure ring continues to move downward, which can improve the pressing effect of the circumferential position of the can cover, and at the same time can prevent the packaging can port from being damaged due to excessive force.
