[0023] 90° joint 1: used to connect flange joint 2, its inner wall has been hardened to improve wear resistance and pressure resistance.
[0024] Flange joint 2: inserted into the 90° joint 1 and connected by bolts to play the role of connection and fixing.
[0025] Rotating joint 3: one end is connected to the joint and the other end is connected to the flange joint 2, which can realize flexible rotation.
[0026] The water retaining plate 7 is made of stainless steel, has corrosion resistance and strength, and can effectively prevent external moisture and impurities from entering the interior of the rotary joint 3.
[0027] 8-way electric slip ring 4: It is sleeved on the connector 6, with a transition mounting plate 5 fixed at the bottom, and is used to transmit current and signals.
[0028] Transition mounting plate 5: A plurality of mounting holes are provided on the transition mounting plate 5, so as to facilitate fixing the whole device at a desired position.
[0029] These structural features work together to make the composite rotary joint 3 of the RH cantilever gunning machine have the advantages of efficient material discharge, flexible rotation, good sealing and protective function, and can meet the requirements for material transportation in industrial production.
[0030] Here’s how it works:
[0031] The material enters through the 90° joint 1, is transferred through the flange joint 2, and then conveyed in the rotary joint 3. The rotary joint 3 can realize flexible rotation to adapt to different discharge angles and position requirements.
[0032] At the connection between the rotary joint 3 and the joint 6 , the water baffle 7 plays a role in blocking external moisture and impurities and preventing them from entering the interior of the rotary joint 3 , thereby ensuring the purity of the material and the normal operation of the joint 6 .
[0033] The 8-way electric slip ring 4 is responsible for transmitting current and signals during the rotation process, ensuring a stable connection with the external control system and realizing real-time monitoring and regulation of the working state of the rotary joint 3 .
[0034] The multiple mounting holes on the transition mounting plate 5 enable the entire device to be firmly fixed at a specific position, ensuring stability during operation.
