After searching, the patent with the announcement number CN216325982U discloses a welding pressure wheel structure for processing galvanized steel plastic pipes, which belongs to the technical field of galvanized steel plastic pipe processing. The structure includes a water tank and a cam. There are several cams. The lower surface of the cam overlaps the upper surface of the rolling structure. The inner surface of the cam is fixedly connected to the outer surface of the rotating shaft. The outer surface of the rotating shaft is sleeved with two second bearings. The welding pressure wheel structure for processing galvanized steel plastic pipes is provided with a rolling structure, a cam, a rotating shaft, a spring, a bracket, a water diversion structure, an air outlet component and a nozzle. The device uses the rotation of the rolling structure as a driving force, and cooperates with the cam and the spring to realize the reciprocating water spraying and exhausting operation of the water diversion structure and the air outlet component, thereby effectively playing a role in cooling and heat dissipation, avoiding the problem of burns of workers during operation, reducing safety hazards, and the device has a simple structure, low cost and good prospects for use.
