Description

Technical Field

[0001] The utility model relates to the technical field of connecting arm rods, and more specifically, to a connecting arm rod of an opening rod of an automated liquid packaging production line. Background Art

[0002] The liquid packaging line is to fill the liquid into an empty barrel, and then rotate and seal the top cover of the empty barrel. This requires the use of an opening rod to rotate and lift the top cover to open the cover. Then, after the liquid is filled into the empty barrel, the opening rod is rotated to lower and tighten the top cover. This requires the opening rod to have the freedom of lifting and rotating. In order to ensure the smooth rotation of the opening rod, a bearing will be set at the connecting arm rod, but this will affect the lifting effect. In addition, the connecting arm rod structure in the existing technology is relatively complex and the cost is high. Utility Model Content
