The size of the reducer is various, and the size of the outer shell is also various. The spray head of the spraying device is prone to be blocked when the paint is dry. The spray head needs to be replaced when it is blocked or damaged. The spray head is replaced manually in the prior art. When the spray head is damaged, the personnel cannot replace the spray head in time, which can cause the spray head to stop spraying the reducer shell and reduce the efficiency of spraying the reducer shell.

The paint is prone to block the spray head when the spray head is dry. Therefore, an automatic spraying production line for reducer shell production with a convenient-to-replace spray head is needed to solve the problem.

[0007] 4.
