[0033] The present invention will be further described in detail below with reference to the accompanying drawings.
[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0035] Example: An automatic spray painting machine, such as Figure 1 As shown, the system includes a spray booth 1, with a spray gun 11 mounted on one side and an air inlet pipe 13 and an exhaust pipe 12 connected to the other side. A disc-shaped workpiece 14 is placed vertically inside the spray booth 1. A first paint tank 2 is mounted on the bottom surface of the spray booth 1, and a first roller 21 is connected to the first paint tank 2. The first roller 21 contacts the lower edge of the workpiece 14. A drive motor 6 is mounted at the bottom of the spray booth 1. The drive motor 6 is connected to the first roller 21 and is used to drive the first roller 21 to rotate.
[0036] like Figure 2 As shown, a second paint box 3 is installed next to the first paint box 2 at the bottom of the spray box 1, and a second roller 31 is connected to the second paint box 3. The first roller 21 and the second roller 31 support the bottom of the workpiece 14. A first anti-tilting member 4 is fixed on the bottom surface of the spray box 1 between the first and second spray boxes 1. A second anti-tilting member 5 is connected to the spray box 1 above the workpiece 14. A third paint box 8 is connected inside the spray box 1 above the second anti-tilting member 5. Two third rollers 81 are installed at the lower part of the third paint box 8, and the two third rollers 81 abut against the edges of the workpiece 14. A second anti-tilting member 5 is connected to the third spray box 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.
[0037] like Figure 3As shown, a guide cylinder 7 is installed downwards at the top inside the paint spray box 1. A guide rod 71 is slidably connected inside the guide cylinder 7, and a spring 72 is sleeved on the outside of the guide rod 71. A pressing block 73 is connected to the end of the guide rod 71 away from the guide cylinder 7. The pressing block 73 is fixedly connected to the third paint box 8. When the workpiece 14 is installed inside the paint spray box 1, the spring 72 is in a compressed state, with one end abutting against the pressing block 73 and the other end abutting against the end of the guide cylinder 7.
[0038] like Figure 4 As shown, the first anti-tilt mechanism has a first through groove 41. The second anti-tilt mechanism has a second through groove 51. When the workpiece 14 is installed in the paint spray box 1, the top and bottom ends of the workpiece 14 are located in the first through groove 41 and the second through groove 51, respectively. Conical rollers 42 are respectively provided on both sides of the first through groove 41 and the second through groove 51. The sides of the conical rollers 42 are close to the surface of the workpiece 14, and when the workpiece 14 rotates, it drives the conical rollers 42 to rotate.
[0039] Instructions for use: When installing the disc-shaped workpiece 14 into the paint spray box 1, first move the third paint box 8 upwards. While moving the third paint box 8 upwards, the workpiece 14 can be directly moved onto the first roller 21 and the second roller 31. When the workpiece 14 abuts against the third roller 81, it compresses the third roller 81, causing the spring 72 to compress, and the third roller 81 and the third paint box 8 move upwards. After the workpiece 14 is in place, the lower edges of the workpiece 14 rest on the first roller 21 and the second roller 31. The top edges of the workpiece 14 abut against the two third rollers 81. The bottom and top ends of the workpiece 14 are located in the first through groove 41 and the second through groove 51, respectively, and are positioned between the conical rollers 42.
[0040] Connect the exhaust pipe 12 to the air pump used for exhaust, and connect the air inlet pipe 13 to the dryer.
[0041] During painting, the drive motor 6 starts, causing the first roller 21 to rotate, which in turn rotates the workpiece 14. As the workpiece 14 rotates, the first roller 21, the second roller 31, the third roller 81, and the fourth roller 91 apply paint to the edges of the workpiece 14. As the workpiece 14 rotates, the tapered roller 42 rotates with it, protecting the edges of the workpiece 14 and preventing scratches from the first and second anti-tilt mechanisms. The air intake pipe 13 supplies dry air into the paint spray box 1, allowing the paint on the workpiece 14 to dry faster. The exhaust pipe 12 discharges waste from the paint spray box 1. Simultaneously, the coordination of air intake and exhaust accelerates the airflow speed within the paint spray box 1, further speeding up the drying of the paint on the workpiece 14 and also accelerating the discharge of waste.
