Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a device for spraying paint on the surface of a metal product. Background Art

[0002] When metal products are manufactured, the plates used in the manufacture of metal products need to be painted to prevent the metal products from being corroded and to protect the metal products. After searching, the patent with Chinese patent authorization announcement number CN219309116U discloses a metal product surface anti-corrosion paint spraying device, including a paint spray can, a main sun gear, a sub-planetary gear, a metal product fixing clamp, a paint spraying equipment and an exhaust gas box. A power motor is installed on the top of the paint spray can, and one end of the rotating rod is installed with the main sun gear. The center point of the main sun gear is connected to one end of the threaded rod in the paint spray can. The threaded hole opened on the paint spraying equipment is sleeved on the threaded rod and threadedly connected to the threaded rod. The main sun gear is meshed with the sub-planetary gear, and a connecting rod is installed at the center point of the sub-planetary gear. The metal product fixing clamp is installed on the connecting rod. The utility model avoids the problem of only being able to spray one side at a time. At the same time, the paint spraying equipment can spray five metal products at the same time, which also improves the efficiency of the spraying operation. The exhaust gas generated by the spraying operation is discharged after filtering, avoiding pollution of the environment and inhalation by the staff to affect their health. However, when painting metal, workers need to place the metal inside the paint spraying device. When taking it out, the metal can be removed only after the sprayed paint has dried. This makes the placement and removal of the metal inconvenient, increases the labor intensity of the workers, and reduces the efficiency of painting the metal. Utility Model Content
