Description

Technical Field

[0002] In the process of packaging production, it is usually necessary to use a bag placing device to transfer pre-made prefabricated bags from a storage bin of the prefabricated bags to a packaging station for bagging operations of materials. At present, common bag placing devices mainly use vacuum suction cups to suck prefabricated bags from station A, and then the suction cups rotate to station B and put down the prefabricated bags. However, during the sucking and rotating process, the suction cups need to maintain a negative pressure state, and the connected air pipes are easy to be wound.

In order to provide negative pressure for the first suction and discharge mechanism 5 and the second suction and discharge mechanism 6 on the rotary frame 4 to suck the packaging bag 15, the rotary joint 2 is provided in this embodiment. The rotary joint 2 is also called an air slip ring or an air-electric unit. It can separately transmit compressed air and vacuum negative pressure, and can also transmit power signals. It is mainly applied to occasions where continuous 360-degree rotation is required and it is necessary to ensure that air pressure, vacuum, power and signals cannot be interrupted.
