A second slide bar 49 for inserting into and sliding along the second limiting groove 47 is fixed to the bottom end of the second rack 14. When the first rack 13 slides left and right, the first slide bar 48 slides along the first limiting groove 46. When the second rack 14 slides left and right, the second slide bar 49 slides along the second limiting groove 47. The stability of the first rack 13 and the second rack 14 when sliding left and right is improved.

[0038] Working principle: Open the switch doors 3 on both the front and rear sides of the outer casing 2. One door panel is placed into the outer casing 2 through the switch door 3 on the front side of the outer casing 2, and is fixed to the first base plate 17 through the clamping structure. Another door panel is placed into the outer casing 2 through the switch door 3 on the rear side of the outer casing 2, and is fixed to the second base plate 19 through the clamping structure.

[0039] The process of placing and fixing the door panel is as follows: before placing the door panel, the second handle 43 is rotated first. The second handle 43 drives the forward and reverse threaded screws 42 to rotate. This drives the two nut blocks 44 to move toward each other. The two nut blocks 44 move toward each other and can drive the two connecting rods 45 to rotate upward at the same time. The two connecting rods 45 lift the plate upward, so that the lifting plate 41 moves upward and passes through the groove 40 until the top of the lifting plate 41 is flush with the top of the second fixed plate 36. Then the door panel is placed so that the center position of the door panel is supported by the lifting plate 41. Then the first handle 28 is rotated, and the first handle 28 drives the first shaft 25 to rotate. The first shaft 25 drives the driving gear 27 to rotate. The driving gear 27 drives the driven gear 29 to rotate. The driven gear 29 drives the second shaft 26 to rotate. The second shaft 26 drives the screw rod 30 to rotate. The screw rod 30 drives the nut seat 31 to slide left and right along the strip cavity 23. The nut seat 31 drives the moving plate 32 to slide left and right along the slide groove 24. The moving plate 32 drives the L-shaped support 21 to slide left and right. Since the thread directions of the two screw rods 30 are opposite, the two L-shaped supports 21 move toward or away from each other. Therefore, the spacing distance between the two L-shaped supports 21 is adjusted according to the length of the door panel. The L-shaped support 21 is moved so that the clamping plate 39 and the second fixed plate 36 are located on the upper and lower sides of the door panel. Then the rotating block 38 is rotated, and the rotating block 38 drives the screw rod 37 to rotate and move downward. The screw rod 37 drives the clamping plate 39 to rotate and move downward, thereby clamping the door panel between the clamping plate 39 and the second fixed plate 36, completing the fixing of the door panel by the clamping structure.

[0040] Then, the first motor 15 is started, and the output shaft of the first motor 15 drives the central gear 12 to rotate counterclockwise. The central gear 12 drives the first rack 13 to slide rightward along the inside of the slide cavity 8, and drives the second rack 14 to slide leftward along the inside of the slide cavity 8. The first rack 13 drives the first slide plate 16 to move rightward along the first strip through groove 10, and at the same time, the second rack 14 drives the second slide plate 18 to slide leftward along the second strip through groove 11. The first slide plate 16 drives the first substrate 17 to move rightward, and at the same time, the second slide plate 18 drives the second substrate 19 to move leftward. As a result, the door panel on the first substrate 17 is located directly below the first spraying device 4, and the door panel on the second substrate 19 is located directly below the second spraying device 5. Then, the switch doors 3 on both the front and rear sides of the outer cover shell 2 are closed. Then, the first spraying device 4 and the second spraying device 5 are started at the same time, and the first spraying device 4 sprays the door panel on the first substrate 17, and at the same time, the second spraying device 5 sprays the door panel on the second substrate 19. The two door panels can be sprayed at the same time. After the spraying of one side of the two door panels is completed, the second motor 34 is started to drive the rotating plate 33 to rotate, thereby driving the door panel to turn over. The other side of the door panel is sprayed. After the spraying of both sides of the door panel is completed, the output shaft of the first motor 15 is rotated in the opposite direction, thereby driving the central gear 12 to rotate clockwise. At this time, the central gear 12 drives the first substrate 17 to move to the left and drives the second substrate 19 to move to the right at the same time, so that the door panel on the first substrate 17 is located directly below the first drying device 6, and the door panel on the second substrate 19 is located directly below the second drying device 7. Then the first drying device 6 and the second drying device 7 are started at the same time, and the first drying device 6 dries the door panel on the first substrate 17, and at the same time, the second drying device 7 dries the door panel on the second substrate 19. After the drying of one side of the two door panels is completed, the second motor 34 is started to drive the rotating plate 33 to rotate, thereby driving the door panel to turn over. The other side of the door panel is dried. The two door panels can be dried at the same time.

[0041] After the drying is completed, the switch doors 3 on the front and rear sides of the outer cover shell 2 are opened, the lifting plate 41 is first raised to support the door panel, and then the clamping plate 39 is loosened and the door panel is removed. This can prevent the door panel from falling after the clamping plate 39 is loosened.

[0042] The utility model can spray and dry two door panels at the same time, thereby improving work efficiency.
