Patent attributes
An automatic capping machine for containers includes a main frame body with a workbench having a bottom conveyor belt disposed thereon, and a lining plate provided below the conveying side of the bottom conveyor belt. A fixed track and a rolling mechanism are disposed on the workbench, and there is a gap between the rolling surface of the rolling mechanism and the fixed track. At least one rolling gap is relatively defined and formed by the space between the rolling surface and the fixed track. The lateral state maintaining structure of a container is disposed above the conveying side of the bottom conveyor belt, so that the convex frame edge of the box body of the container is maintained and limited above the fixed track. A through air collision avoidance section is formed in the rolling section defined on the setting path of the lining plate.
