The invention discloses an automatic paint spraying
production line with a movable
processing chamber. The automatic paint spraying
production line comprises a supporting frame, the
processing chamber, a fixing structure, lifting hooks connected to the lower portion of a circulating track, the circulating track connected with the supporting frame and two sets of paint spraying pieces moving up and down, wherein the
processing chamber is located below the circulating track and comprises a center bottom plate, a left top plate, a right top plate, a left bottom
assembly and a right bottom
assembly, the left top plate and the right top plate are bounded by the circulating track, the sections of the left bottom
assembly and the right bottom assembly are L-shaped, and a left transverse part of the left bottom assembly and a right transverse part of the right bottom assembly are slidably connected with the two ends of the center bottom plate; and the end, away from the left transverse part, of a left vertical part of the left bottom assembly is slidably connected to the bottom of the left top plate, and the end, away from the right transverse part, of a right vertical part of the right bottom assembly is slidably connected to the bottom of the right top plate. According to the automatic paint spraying
production line, the size of the processing chamber can be controlled, so that flexible adjustment of the size of the processing chamber is achieved, the paint spraying effect is guaranteed, and the paint spraying amount is reduced.
