[0025] The lifting structure 17 includes a third motor 171, a screw rod 172 and a movable block 173. The third motor 171 is fixed to the top of the vertical plate 2. The output shaft of the third motor 171 is fixed to one end of the screw rod 172. The other end of the screw rod 172 is rotatably connected to the inner wall of the vertical plate 2. The inside of the movable block 173 is threadedly connected to the surface of the screw rod 172. The rear of the movable block 173 is slidably connected to the inner wall of the vertical plate 2. The surface of the movable block 173 is fixed to the rear end of the support plate 3. In this way, when the support plate 3 is driven to be lifted, the third motor 171 can be started, and the screw rod 172 can be driven to rotate, and the movable block 173 and the support plate 3 can be driven to be lifted up and down at the same time.

[0026] The front end of the support plate 3 is internally connected to a rotating tube 4 for rotation. The top of the support plate 3 is provided with a driving structure 13 for driving the rotating tube 4 to rotate. The left side of the bottom end of the rotating tube 4 is fixedly connected to a fixed plate 5. The other end of the fixed plate 5 is fixed to a connecting box 6. The inside of the connecting box 6 is movably connected to a movable tube 10. The front end of the movable tube 10 is connected to a nozzle 11. The inside of the rotating tube 4 is movably connected to a connecting tube 12, and the two ends of the connecting tube 12 are respectively connected to the spraying device 15 and the rear end of the movable tube 10. The connecting tube 12 is movable. A telescopic hose, and its extension length is greater than the distance that the support plate 3 moves up and down on the surface of the vertical plate 2, so that when the support plate 3 moves, or when the movable tube 10 moves, it will not cause pulling on the connecting tube 12. A first motor 7 is fixed to the top of the connecting box 6, and the output shaft of the first motor 7 extends to the inside of the connecting box 6 and is fixed with a gear 8. A tooth 9 is arranged on the left side of the movable tube 10, and the surface of the gear 8 is meshed with the tooth 9. A shielding structure 16 for shielding the tubular workpiece is arranged below the support plate 3.

[0027] The driving structure 13 includes a second motor 131, a first bevel gear 132 and a second bevel gear 133. The second motor 131 is fixed on the top of the support plate 3. The output shaft of the second motor 131 is fixed to one side of the first bevel gear 132. The other side of the first bevel gear 132 is meshed with the second bevel gear 133. The interior of the second bevel gear 133 is fixed to the top surface of the rotating tube 4. In this way, when the rotating tube 4 is driven to rotate, the second motor 131 can be started, and the first bevel gear 132 can be driven to rotate, and at the same time, the first bevel gear 132 can be driven to rotate, thereby driving the second bevel gear 133 and the rotating tube 4 to rotate.

[0028] The shielding structure 16 includes a folding plate 161, an electric push rod 162 and a shielding plate 163. The folding plate 161 is fixed on both sides in front of the bottom of the support plate 3, and the electric push rod 162 is arranged on the top of the folding plate 161. The output end of the electric push rod 162 extends to the bottom of the folding plate 161 and is fixed to the top of the shielding plate 163. In this way, before spraying the inner wall of the workpiece, the electric push rod 162 can be started and the shielding plate 163 can be driven to move downward so that the shielding plate 163 is located on the top surface of the workpiece, thereby preventing the paint from splashing randomly. A movable groove 18 is opened in the middle position of the top of the shielding plate 163. The size of the movable groove 18 is larger than the size of the combination of the rotating tube 4, the fixed plate 5 and the connecting box 6. In this way, as the shielding plate 163 moves, it will not collide with the fixed plate 5 and the connecting box 6.

[0029] The upper and lower sides of the movable tube 10 are fixedly connected with a slide plate 14, and the surface of the slide plate 14 is slidably connected to the inside of the connection box 6, so that the movable tube 10 can be auxiliary supported and its stability during movement can be maintained.

[0031] Working principle: When in use, the tubular workpiece can be placed on the top of the base plate 1 and then fixed by the clamping assembly. After the fixation is completed, the support plate 3 can be driven to move downward by the lifting structure 17 until the nozzle 11 is located inside the workpiece. Then, according to the size of the inner diameter of the workpiece, the first motor 7 can be started, and the gear 8 can be driven to rotate. At the same time, the movable tube 10 can be driven to move by the teeth 9 until the nozzle 11 is close to the inner wall of the workpiece. Then, the top of the workpiece can be covered by the shielding structure 16, and then the paint is transported to the inside of the connecting tube 12 through the spraying equipment 15, and sprayed out through the nozzle 11. During the spraying process, the rotating tube 4 can be driven to rotate by the driving structure 13, and the fixed plate 5, the connecting box 6, the movable tube 10 and the nozzle 11 can be driven to rotate together, so that the nozzle 11 can evenly spray the inner wall of the workpiece.
