Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a ton bag hanging folding arm mechanism. Background Art

[0002] For existing equipment to hang ton bags, four corners must be hung to lift the entire bag weight. After hanging two bag corner slings on one side of the ton bag and fixing the feed port, another two slings must be hung on the other side. However, since the equipment is a large bagging equipment, it is impossible to reach the hanging point on the other side with just the arm span.
