Description

Technical Field

[0001] The present application relates to the field of rotary connection technology, and in particular to a slip ring suitable for packaging machinery. Background Art

[0002] Slip rings, essential core components of rotating platforms or joints on packaging machinery, are installed at the center of the equipment's rotation. They transmit various signals and currents between components, enabling 360° unlimited forward and reverse rotation and real-time current and signal transmission. The slip ring's rotor uses direct lead wires and third-party terminal blocks to connect to the terminal device. The slip ring's stator also uses direct lead wires and third-party terminal blocks to connect to the terminal device.

[0003] In order to facilitate the connection between slip rings and devices, the prior art connection method for slip rings and devices is to connect the wires of the slip rings to the terminal device interface by ordinary welding, or to calculate the length of the lead wires of the slip rings, directly lead out the wires of the stator and rotor of the slip rings, use the terminal blocks provided by a third party, weld the terminal blocks to the wires, and then connect the terminal blocks to the terminal device for wiring;

[0004] There are some problems with the above two connection methods: the wires are connected by ordinary welding, which makes it difficult to connect the product wires and has low reliability and safety; the lead and terminal connection method requires the wires to be led out and connected to the wires of the equipment one by one during the slip ring installation, which is cumbersome. The slip ring occupies a large installation space of the equipment and is prone to errors when calculating the wire length. Utility Model Content

[0005] The purpose of this application is to provide a slip ring suitable for packaging machinery to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solution: a slip ring suitable for packaging machinery, comprising a stator part and a rotor part rotatably connected to the stator part, and also comprising a stator connection part connected to the outer surface of the stator part for connecting to the terminal device wire and a rotor connection part connected to one side of the rotor part for connecting to the rotating terminal device wire.

[0007] In one embodiment, the stator connection part includes a stator connection board fixedly connected to the outer surface of the stator part and electrically connected to the stator part, a connection box connected to one side of the stator connection board, a waterproof cover screwed to the upper end of the connection box, and a wire inlet opened on one side of the connection box.

[0008] In one embodiment, a copper bolt for tightening the wire is screwed onto the stator terminal board.

[0009] In one embodiment, the rotor connection part includes a rotor connection plate fixedly connected to one side of the rotor part, two waterproof covers connected to one side of the rotor connection plate by bolts, two copper bolts screwed to the rotor connection plate, and a hollow groove is opened in the middle of the rotor connection plate to facilitate the passage of the wires.

[0010] In one embodiment, a stator anti-rotation piece is fixedly connected to one side of the stator part.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1) The present application can be installed in packaging machinery and equipment to achieve 360° unlimited forward and reverse rotation and real-time transmission of current and signals; the rotor and stator parts are both connected by bolts fixed with wires, and the bolts are integrated and fixed on the slip ring, saving overall installation space and making wire connection more convenient, thereby improving connection reliability and safety; the slip ring can meet the requirements of installation size and external size, and has the characteristics of simple process, long life, small size, stable transmission, maintenance-free, and high bolt connection reliability.

[0013] 2) Since both the stator and rotor of this application use bolt-fixed connection wires, the overall installation space of the slip ring can be saved, and the reliability and safety of the wire connection can be improved. In addition, this application itself does not require external wires, and only the wires on the terminal device need to be connected to the slip ring, making the installation of the slip ring product simpler and more convenient.
