Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: an automotive painting device, including a paint booth 1, an underground drive motor 2, and a turntable 3. The turntable 3 is installed in the center of the bottom surface of the paint booth 1, and the bottom end of the turntable 3 is connected to the shaft of the underground drive motor 2. An exhaust fan 4 is installed at the top of the paint booth 1, and a filter screen 5 is connected to the bottom end of the exhaust fan 4. Sliding guide rails 6 are installed on the left and right inner walls of the paint booth 1. Screw drive motors 7 are installed on the left and right sides of the top of the paint booth 1, and screws 8 are installed at the ends of the screw drive motors 7. A paint pipe fixing bracket 10 is slidably connected to the sliding guide rail 6 through a slider 9. Several equally spaced paint nozzles 11 are arranged on the paint pipe fixing bracket 10 from top to bottom. A paint sprayer 12 is fixedly installed on the outside of the paint pipe fixing bracket 10, and a feed port 13 is connected to the outside of the paint sprayer 12.
[0021] The top of the paint sprayer 12 is connected to the screw nut slider 15 via the fixing rod 14, and the screw nut slider 15 and the screw 8 are slidably connected. The paint sprayer 12, the paint spray tube fixing bracket 10 and the fixing rod 14 are a fixed integrated structure.
[0022] Hot air blowers 16 are installed on the bottom of the left and right sides of the spray booth 1. Lifting motors 17 are fixedly installed inside the left and right side walls of the spray booth 1. The bottom end of the lifting motor 17 is connected to a telescopic shaft 18. A clamping sleeve 19 is provided at the bottom of the telescopic shaft 18. An air outlet pipe 20 is fixedly installed inside the clamping sleeve 19. The air outlet pipe 20 is rotatably connected to the inner wall of the spray booth 1 through a hinge spring 21. The end of the air outlet pipe 20 is connected to the hot air blower 16 through a connecting hose.
[0023] The bottom surface of the spray booth 1 is provided with two grooves 22, and the two grooves 22 are located on the left and right sides of the turntable 3 respectively. A drain pipe 23 is connected to the center of the bottom of the groove 22, and a piston cover 24 is provided at the end of the drain pipe 23.
[0024] The lead screw drive motor 7 drives the paint spray tube fixing frame 10 and the paint sprayer 12 to move parallel to each other in the cavities on the left and right sides of the inner wall of the paint spray booth 1 through the cooperation of the lead screw 8 and the lead screw nut slider 15, thereby adjusting the back-and-forth movement of the paint spray head 11 in the paint spray booth 1.
[0025] The feed inlet 13 is exposed on the outside of the spray booth 1, which facilitates the input of paint into the spray machine 12. The spray machine 12 and several spray heads 11 with equal spacing and height on the spray pipe fixing frame 10 are connected by a conduit.
[0026] The lifting motor 17 drives the air outlet pipe 20 to swing up and down through the telescopic shaft 18, thereby adjusting the tilt angle at the air outlet port of the air outlet pipe 20. The bottom of the telescopic shaft 18 and the clamping sleeve 19 are not connected. When the telescopic shaft 18 extends downward, it will contact and abut against the clamping sleeve 19, causing the clamping sleeve 19 to make lever movement. Under normal conditions, the clamping sleeve 19 is subjected to the action of the hinge spring 21, and the right end is in a downward tilted state.
[0027] Working principle:
[0028] In this device structure, during the painting process, the vehicle body first moves to the turntable 3 in the center of the paint booth 1. Then, the buried drive motor 2 works, driving the turntable 3 to rotate, allowing the vehicle body to rotate and adjust its angle within the paint booth 1. Next, the lead screw drive motor 7 works. In this structure, the lead screw drive motor 7 is a bidirectional drive motor that drives the lead screw 8 to rotate in both directions. The lead screw nut slider 15 is slidably mounted on the lead screw 8. The lead screw nut slider 15 has a circulation channel and several balls inside. When the lead screw 8 rotates, the lead screw nut slider 15 will change the rotational force into linear lateral movement under the action of the lead screw transmission. Through the forward and reverse rotation of the lead screw 8, the lead screw nut slider 15 moves laterally to the left or right on the lead screw 8.
[0029] The bottom end of the lead screw nut slider 15 is connected to the fixed rod 14, thereby driving the fixed rod 14 to move laterally. This can drive the paint spray tube fixing frame 10, the paint sprayer 12 and the fixed rod 14 to move back and forth along the sliding guide rail 6, so that the paint spray head 12 can move back and forth repeatedly to achieve the painting operation of the vehicle body.
[0030] After the painting is completed, the lifting motor 17 and the hot air blower 16 work. The hot air blower transmits hot air to the air outlet 20 through the connecting hose and blows it out from the end of the air outlet 20. The lifting motor 17 drives the clamping sleeve 19 and the air outlet 20 to swing up and down at the bottom of the inner wall on both sides of the paint booth 1 through the telescopic shaft 18, adjusting the inclination between the air outlet 20 and the ground, so that the hot air can dry the paint surface at different heights on both sides of the vehicle body, achieving the effect of quickly drying the paint surface after painting.
[0031] Throughout the entire process of spraying and drying the paint surface, the exhaust fan 4 works continuously, exhausting the air inside the spray booth 1 upwards. During the upward exhaust process, the air inside the spray booth 1 is purified by the filter screen 5, which filters out the particulate impurities remaining in the air due to the paint mist.
[0032] After the painting is completed, the paint on the walls and floor inside the spray booth 1 is washed with clean water, and the wastewater after rinsing is discharged from the drain pipe 23 through the groove 22.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
