If the cleaning of the gun washing device for the car repair spray paint robot is not in place, the sprayed paint may contain paints of other colors, thereby causing color difference and affecting the paint repair work. If the cleaning solvent on the pipeline or the rotary cup is not cleaned up after the cleaning is completed, it will remain on the pipe wall. When these residues are mixed with the paint sprayed subsequently, shrinkage cavities may be formed, affecting the spraying quality. Therefore, the specific steps are as follows: the threaded rod 21 is rotated to drive the cleaning brush 22 to rotate and lift, and the end of the cleaning brush 22 is brushed against the inner wall of the car repair spray paint gun 1 to brush off the paint attached to the inner wall of the car repair spray paint gun 1, so as to facilitate the subsequent replacement of the repair paint by the car repair spray paint gun 1.

[0020] The improvement of this embodiment is that:

[0021] The threaded rod 21 is rotated to drive the cleaning brush 22 on the outer wall to rise and fall and rotate on the outer wall of the threaded rod 21 (when rotating, because the threaded rod 21 and the cleaning brush 22 are rotatably connected, the cleaning brush 22 rotates with the threaded rod 21. When lifting and lowering, the cleaning brush 22 can be manually twisted to slide along the outer wall of the threaded rod 21 to rise and fall, thereby changing the cleaning position). The cleaning brush 22 is rotated and brushed against the inner wall of the automobile repair paint spray gun 1 to clean the repair paint attached to the inside of the automobile repair paint spray gun 1 from the inner wall of the automobile repair paint spray gun 1, thereby preventing the automobile repair paint spray gun 1 from producing mixed color paint due to inadequate internal cleaning when replacing the paint, thereby improving practicality.

[0022] In order to strengthen the cleaning of the inside of the automobile repair spray paint gun 1, a mounting plate 20 is provided above the automobile repair spray paint gun 1, a sealing cover 201 is fixedly connected below the mounting plate 20, the lower end of the sealing cover 201 is aligned with the upper end of the automobile repair spray paint gun 1, a threaded rod 21 is rotatably connected to the axis of the lower end of the sealing cover 201, a rotating block 211 is rotatably connected to the outer wall of the threaded rod 21, and a plurality of cleaning brushes 22 are evenly arranged around the outer wall of the rotating block 211, a paint spray pipe 10 is provided inside the automobile repair spray paint gun 1, and the end of the cleaning brush 22 fits the inner wall of the paint spray pipe 10, a first motor 23 is fixedly installed above the mounting plate 20, and the end of the first motor 23 extends into the output shaft of the inner wall of the mounting plate 20 and is fixedly connected to the end of the threaded rod 21, a solvent tank 24 is fixedly installed above the mounting plate 20, and a solvent tank 24 is fixed below the solvent tank 24.

The solvent box 24 transports solvent to the connecting pipe 241, and the connecting pipe 241 transports solvent to the sealing cover 201. The sealing cover 201 is communicated with the inner wall of the paint spray pipe 10. The connecting pipe 241 transports the solvent to the inside of the paint spray pipe 10 through the sealing cover 201. The first motor 23 drives the threaded rod 21 at the end to rotate on the inner wall of the paint spray pipe 10, and the threaded rod 21 drives the rotating block 211 of the outer wall to rotate and rise and fall. The rotating block 211 drives the cleaning brush 22 of the outer wall to rotate and rise and fall in contact with the inner wall of the paint spray pipe 10. The end of the cleaning brush 22 is in contact with the inner wall of the paint spray pipe 10 and brushes. The solvent decomposes the paint, and the cleaning brush 22 cleans the residual paint attached to the inner wall of the paint spray pipe 10 from the inner wall of the paint spray pipe 10.

[0023] Considering that it is inconvenient for the cleaning brush 22 to enter the interior of the paint spray pipe 10 for cleaning, an adjusting plate 25 is slidably connected to the outer side of the mounting plate 20, and a sliding groove 251 is provided on the surface of the adjusting plate 25. A sliding block 202 is fixedly connected to the outer side of the mounting plate 20, and the sliding block 202 is slidably adapted to the inner wall of the sliding groove 251. The inner wall of the sliding block 202 is rotatably connected to a screw rod 26, and the lower end of the screw rod 26 is rotatably connected to a fixed plate 261. The outer side of the fixed plate 261 is fixedly connected to the outer side of the adjusting plate 25, and a second motor is fixedly connected below the fixed plate 261. 262, the output shaft of the second motor 262 end extending into the inner wall of the fixed plate 261 is fixedly connected to the end of the screw rod 26, the second motor 262 drives the screw rod 26 to rotate above the fixed plate 261, the rotation of the screw rod 26 drives the sliding block 202 to move up and down, the sliding block 202 slides horizontally on the inner wall of the sliding groove 251, the sliding block 202 drives the mounting plate 20 to slide on the outside of the adjusting plate 25, the mounting plate 20 drives the threaded rod 21 to insert into the inner wall of the paint spray pipe 10 until the bottom of the sealing cover 201 fits with the top of the automobile repair spray gun 1.

As the tilt angle increases, the efficiency of the solvent and residual paint flowing out is higher. When it is flipped to 120°, the tilt angle of the car repair paint gun 1 reaches the maximum, and the opening of the paint duct 10 is not directly above the fan blades 291. Even if some of it splashes onto the fan blades 291, it can be imagined in the technical field that the solvent and residual paint poured out of the paint duct 10 can be promptly received). The car repair paint gun 1 is tilted, and the solvent and residual paint inside the paint duct 10 flow out from the inside of the paint duct 10.

[0025] Considering that the inner wall of the paint spraying pipe 10 needs to be kept dry before adding new repair paint, a bottom plate 28 is fixedly connected to the bottom of the adjustment plate 25, and a third motor 29 is fixedly installed under the bottom plate 28. The output shaft of the end of the third motor 29 extends into the inner wall of the bottom plate 28 and is fixedly connected to a fan blade 291. The end of the fan blade 291 rotates above the bottom plate 28, and the third motor 29 drives the fan blade 291 to rotate. The fan blade 291 blows air to the inside of the paint spraying pipe 10 until the inside of the paint spraying pipe 10 is blown clean to prevent the residue from mixing with the new paint.

[0026] In summary, the working principle of this scheme is as follows:
