Description

Technical Field

[0001] The utility model relates to the technical field of barrel filling, in particular to a barrel cap screwing device. Background Art

[0002] In a filling production line, screwing the barrel cap is a very important step. Before filling, the barrel cap needs to be unscrewed, and after filling, the barrel cap needs to be tightened. However, existing screwing devices generally use a motor to drive a jaw assembly to descend, and then use a motor or a cylinder to drive the jaws to clamp the edge of the barrel cap and then rotate. However, 200L barrels are recyclable, and some 200L barrels recycled and used by factories may be deformed, resulting in non-horizontal barrel mouths and barrel caps. Moreover, the edge of the barrel cap is relatively thin, resulting in the jaws sometimes being unable to firmly clamp or even unable to clamp the barrel cap, thus causing instability when screwing the barrel cap.
