[0036] In this embodiment, during operation, the product to be painted (car body or car body parts) is placed on the first comb frame 6. Then, the first power mechanism drives the transmission belt 10 to move, thereby moving the product. When the product moves to the position below the hot air nozzle 222, both partitions 3 on both sides of the product are placed inside the outer cover 2. To achieve positioning of the partitions 3, mounting holes are opened on the outer cover 2, and infrared sensors are installed in the mounting holes. When the partitions 3 block the infrared sensors, the infrared sensors feed back signals to the controller, which then controls the second servo motor 29 to stop driving. A second hose 242 is connected to the paint nozzle 221, connecting the second hose 242 to the pump output. The pump draws paint into the paint nozzle 221, and the paint is then sprayed onto the surface of the product through the paint nozzle 221. During this process, the cylinder 15 drives two racks 16 to reciprocate synchronously. The racks 16 then drive the gear 9 to reciprocate, and the gear 9 drives the placement frame mechanism to rotate. Simultaneously, the first... A servo motor 25 drives the first take-up roller 181 to rotate, thereby realizing the winding and unwinding of the belt 32. The tape measure spring 28 ensures that the belt 32 is always taut during the unwinding process, which in turn drives the hot air nozzle 222 and the paint spray nozzle 221 to move back and forth, thereby improving the coating effect of the product and reducing the coating dead angle. The outer cover 2 and the partition 3 can reduce the spread of paint. When the painted product moves to the bottom of the paint spray nozzle 221, the drive belt 10 stops moving. During this process, the unloading work can continue. At this time, the next product moves to the bottom of the paint spray nozzle 221, and the first hose 241 on the hot air nozzle 222 is connected to the hot air blower 21. The hot air blower 21 generates hot air and delivers it to the inside of the hot air nozzle 222. By driving the product to rotate and the paint spray nozzle 221 to move back and forth, the product can be dried in all directions. The generated hot air and harmful gases flow into the interior of the purifier through the ventilation pipe. The gas is discharged after being treated by the purifier.
