The rotation of the gear 7 drives the rotating rod 6 to rotate, and the rotation of the rotating rod 6 drives the workpiece to rotate, thereby making the workpiece rotate itself when passing through the spray nozzle 13, so as to facilitate comprehensive spraying. At the same time, the driving motor 9 drives The eccentric wheel 10 rotates, and when the eccentric wheel 10 rotates, it drives the connecting rod 14 to move up and down. The up and down movement of the connecting rod 14 drives the movable plate 12 to slide up and down on the surface of the fixed block 11. The up and down sliding of the movable plate 12 drives the spray nozzle 13 to reciprocate up and down. The up and down reciprocating movement of the spray nozzle 13 is used to spray the workpiece more comprehensively and evenly, so as to facilitate the spraying of larger workpieces and tubular workpieces on the production line, and spray larger workpieces and tubular workpieces evenly. There is no need to manually adjust the position of the workpiece during the spraying process, which is convenient for users to use and improves the spraying efficiency.
