[0020] Reference Figures 1 to 4 As shown, the present invention provides a tower spraying and polishing device, comprising: a spraying machine body 1, an input pair of rollers 2, a tower body 3 and an output pair of rollers 4, the input pair of rollers 2 and the output pair of rollers 4 are distributed on the left and right sides of the spraying machine body 1, and the tower body 3 runs through the cavity of the spraying machine body 1.

[0021] A left fixed plate 11 and a right fixed plate 13 are welded on the left and right side ends of the spray machine body 1. The upper and lower ends of the left fixed plate 11 and the right fixed plate 13 are respectively connected to the input roller 2 and the output roller 4 through an electric slide mechanism 41. The right side end of the right fixed plate 13 is connected to a connecting plate 56 through a hydraulic cylinder 52. The left and right sides of the connecting plate 56 are alternately welded with clamping blocks 53. The clamping blocks 53 are respectively screwed with the first arched polishing frame 5 and the second arched polishing frame 51 through fastening bolts 55. The inner curved surfaces of the first arched polishing frame 5 and the second arched polishing frame 51 are both fitted with polishing sheets 54.

[0022] First, place a section of the tower body 3 at the input roller 2 with the help of external equipment. The input roller 2 here is precisely adjusted up and down through an electric slide mechanism 41. The electric slide mechanism 41 includes a motor, a lead screw, a slider and a guide rail. The motor drives the lead screw to rotate, the lead screw and the slider are threaded together, the slider and the guide rail are slidably matched, and the sliders are respectively connected to the frames of the input roller 2. The up and down movement of the slider on the guide rail is controlled by the forward and reverse rotation of the motor, thereby realizing the up and down position adjustment of the input roller 2. In this way, the position of the input roller 2 can be flexibly adjusted according to the actual size and shape of the tower body 3, ensuring that the tower body 3 can smoothly enter the cavity of the spray body 1, and the tower body 3 moves into the cavity of the spray body 1 at a uniform speed.

[0023] During the movement of the tower body 3, dust is first removed through the dust suction port 14. The dust suction port 14 is arranged on the inner cavity wall of the spray body 1, distributed in an annular shape, and the dust suction port 14 is connected to a negative pressure pipe 15. A paint nozzle 16 is installed at the right end of the dust suction port 14, and the paint nozzle 16 is distributed in an annular shape on the outer side of the cylinder surface of the tower body 3. The tower body 3 is connected to a paint barrel through a spray pipe 17. The annularly distributed paint nozzle 16 can fully and evenly spray the paint on the cylinder surface of the tower body 3. At the same time, the dust suction port 14 is convenient for dust removal on the cylinder surface of the tower body 3 before spraying, and can also absorb the gas mixed with paint in the inner cavity of the spray body 1 to prevent the paint gas from being emitted into the external environment.

[0024] The tower body 3 after spraying the paint moves to the curing heating tube 6 for curing. The curing heating tube 6 is installed on the cavity wall of the spraying machine body 1 and is distributed at the right end of the paint nozzle 16. The curing heating tube 6 is electrically connected to the temperature controller 61, and the temperature controller 61 is located on the upper surface of the spraying machine body 1. The temperature controller 61 is used to control the curing temperature of the curing heating tube 6. The curing heating tube 6 is used to cure and dry the coating on the surface of the tower body 3 after uniform spraying, so as to facilitate the next step of polishing of the cured coating on the surface of the tower body 3.

[0025] The solidified tower body 3 is moved out from the output roller pair 4. The output roller pair 4 is also adjusted up and down by an electric slide mechanism 41, and its principle is the same as that of the input roller pair 2. A distance sensor 42 is installed on the frame side of the output roller pair 4. The distance sensor 42 here is a laser distance sensor, and the laser beam it emits is perpendicular to the frame side of the output roller pair 4. When the upper and lower frame distances of the output roller pair 4 change, the distance value detected by the laser distance sensor changes, and the change value is transmitted to the central control box 12. The central control box 12 controls the electric slide mechanism 41 to adjust the upper and lower frame spacing of the output roller pair 4 according to the change value, so that it keeps in contact with the upper and lower cylinder surfaces of the tower body 3, so that the tower body 3 can be smoothly output from the output roller pair 4, and ensure the stability of the position of the tower body 3 during the output process.

[0026] The tower body 3 after being moved out enters the inner side of the first arch polishing rack 5 and the second arch polishing rack 51, and contacts the polishing sheet 54. The tower body 3 is polished under the action of the hydraulic cylinder 52. The piston of the hydraulic cylinder 52 is fixedly connected to the connecting plate 56, and the reciprocating motion of the piston in the hydraulic cylinder 52 drives the connecting plate 56 to move left and right, so that the first arch polishing rack 5 and the second arch polishing rack 51 move back and forth on the upper and lower cylinder surfaces of the tower body 3 for polishing. And the movement speed of the hydraulic cylinder 52 can be adjusted by the central control box 12, so that the speed and effect of polishing can be flexibly adjusted according to the actual polishing needs.

[0027] The first arch polishing frame 5 and the second arch polishing frame 51 are driven back and forth by the hydraulic cylinder 52 to polish the upper and lower surfaces of the tower body 3 through the polishing sheet 54 on the inner side. This design allows the polishing sheet 54 to fully contact the outer surface of the tower, which is convenient for increasing the polishing area of ​​the spray polishing device and improving the processing efficiency of the integrated spray polishing device.

[0028] During the whole process, an electric push rod 71 is embedded and fixed in the middle of the left fixed plate 11 and the right fixed plate 13. The side end of the electric push rod 71 is connected to the limit baffle 7. The side of the limit baffle 7 contacts the tower body 3 through the ball 72. The electric push rod 71 is used to push the limit baffle 7 to move forward and backward, so that the limit baffle 7 rolls with the front and rear cylinder surfaces of the tower body 3 through the ball 72. When the tower body 3 is rolling on the roller surface of the input roller 2 and the output roller 4, the limit baffle 7 can limit the position of the tower body 3, avoid the tower body 3 from being offset during the spraying and polishing process, and ensure the stability of the spraying and polishing process of the tower body 3.

[0029] The tower spray polishing device of the present invention can effectively solve the problem of poor polishing efficiency caused by the small contact area between the polishing wheel and the tower body in the prior art through the coordinated work of the above-mentioned components. It is convenient for the polishing mechanism to fully contact the outer surface of the tower, increase the polishing processing area of ​​the spray polishing device, facilitate the thorough and complete polishing of the tower surface, ensure that the tower surface coating after spray polishing is smoother and brighter, improve the processing efficiency of the integrated spray polishing device, and is suitable for the tower spray polishing device.
