The first roller 21 and the second roller 31 support the bottom of the workpiece 14. A first anti-tip member 4 is fixed to the bottom surface of the painting booth 1 between the first painting booth 1 and the second painting booth 1. A second anti-tip member 5 is attached to the paint spray booth 1 above the workpiece 14. A third paint box 8 is connected above the second anti-tilting member 5 in the paint spraying box 1, two third rollers 81 are mounted at the lower part of the third paint box 8, and the two third rollers 81 respectively abut against the edge of the workpiece 14. A second anti-roll member 5 is connected to the third paint booth 1 between the two third rollers 81. The first roller 21, the second roller 31, the third roller 81, and the fourth roller 91 are parallel to each other.

As shown in fig. 3, a guide cylinder 7 is installed downward at the top inside the paint spray box 1, a guide rod 71 is slidably connected in the guide cylinder 7, and a spring 72 is sleeved outside the guide rod 71. One end of the guide rod 71 far away from the guide cylinder 7 is connected with a press block 73. The pressing block 73 is fixedly connected with the third paint tank 8. When the workpiece 14 is mounted in the oil spray box 1, the spring 72 is in a compressed state, and one end of the spring abuts against the abutting block 73 and the other end abuts against the end of the guide cylinder 7.

As shown in fig. 4, the first anti-roll mechanism has a first through groove 41. The second anti-roll mechanism has a second through slot 51.
