Summary of the Invention

[0003] In order to overcome the defects existing in the prior art, a tower barrel spraying and polishing device is provided to solve the problem that the contact area between the polishing wheel and the tower barrel body in the prior art is small, resulting in poor polishing efficiency.

[0004] To achieve the above object, a tower barrel spraying and polishing device is provided, including: a spraying machine body, an input pair of rollers, a tower barrel body, and an output pair of rollers. The input pair of rollers and the output pair of rollers are distributed on the left and right sides of the spraying machine body, and the tower barrel body penetrates through the cavity of the spraying machine body.

[0007] Further, a paint spray head is installed at the right end of the dust suction port; and the paint spray heads are annularly distributed on the outer side of the barrel surface of the tower barrel body. The tower barrel body is connected to a paint barrel through a spray pipe.

[0008] Further, a curing heating pipe is installed on the cavity wall of the spraying machine body; and the curing heating pipes are distributed at the right end of the paint spray heads. The curing heating pipes are electrically connected to a temperature controller; and the temperature controller is located on the upper surface of the spraying machine body.

[0009] Further, the tower barrel body rolls and contacts at the upper and lower spacing positions of the input pair of rollers and the output pair of rollers. Distance sensors are installed on the side surfaces of the frames of the input pair of rollers and the output pair of rollers.

[0010] Further, an electric push rod is embedded and fixed in the middle of the left fixing plate and the right fixing plate. A limiting baffle is connected to the side end of the electric push rod. The side surface of the limiting baffle contacts the tower barrel body through a ball.

[0011] Further, the inner sides of the first arched polishing frame and the second arched polishing frame contact the upper and lower barrel surfaces of the tower barrel body through polishing sheets; and the right side of the first arched polishing frame is connected to the second arched polishing frame through a connecting plate.

[0021] Referring to Figures 1 to 4 As shown, the present invention provides a tower barrel spraying and polishing device, including: a spraying machine body 1, an input pair of rollers 2, a tower barrel 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 barrel body 3 penetrates through the cavity of the spraying machine body 1.

[0022] On the left and right sides of the spraying body 1, the left fixing plate 11 and the right fixing plate 13 are welded and distributed. The upper and lower ends of the left fixing plate 11 and the right fixing plate 13 are respectively connected with the input pair of rollers 2 and the output pair of rollers 4 through the electric sliding table mechanism 41. The right side end of the right fixing plate 13 is connected with the connecting plate 56 through the hydraulic cylinder 52. The clamping blocks 53 are welded staggeredly on the left and right side surfaces of the connecting plate 56. The clamping blocks 53 are respectively screwed with the first arched polishing frame 5 and the second arched polishing frame 51 through the fastening bolts 55. The inner arc surfaces of the first arched polishing frame 5 and the second arched polishing frame 51 are both attached with polishing sheets 54.

[0023] First, place a section of tower barrel body 3 at the input pair of rollers 2 with the help of external equipment. Here, the input pair of rollers 2 realizes precise adjustment of the up and down positions through the electric sliding table mechanism 41. The electric sliding table 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 is in threaded cooperation with the slider. The slider is in sliding cooperation with the guide rail. The slider is respectively connected with the frame of the input pair of rollers 2. By controlling the forward and reverse rotation of the motor, the up and down movement of the slider on the guide rail is realized, so as to realize the up and down position adjustment of the input pair of rollers 2. In this way, according to the actual size and shape of the tower barrel body 3, the position of the input pair of rollers 2 can be flexibly adjusted to ensure that the tower barrel body 3 can smoothly enter the cavity of the spraying body 1 and move into the cavity of the spraying body 1 at a uniform speed.

[0024] During the movement of the tower barrel body 3, it is first dust-removed through the dust suction port 14. The dust suction port 14 is arranged on the inner cavity wall of the spraying body 1 and is distributed in a ring shape. The dust suction port 14 is connected with a negative pressure pipeline 15. A paint spray head 16 is installed at the right side end of the dust suction port 14. The paint spray heads 16 are distributed in a ring shape on the outer side of the barrel surface of the tower barrel body 3. The tower barrel body 3 is connected with a paint barrel through a spray pipe 17. The annularly distributed paint spray heads 16 can fully and evenly spray the paint on the barrel surface of the tower barrel body 3. At the same time, the dust suction port 14 is convenient for dust-removing the barrel surface of the tower barrel body 3 before spraying, and can also suck the gas mixed with paint in the inner cavity of the spraying body 1 to avoid the emission of paint gas into the external environment.

[0025] The tower barrel body 3 after spraying the paint moves to the curing heating pipe 6 for curing. The curing heating pipe 6 is installed on the cavity wall of the spraying body 1 and is distributed at the right side end of the paint spray head 16. The curing heating pipe 6 is electrically connected with a temperature controller 61. The temperature controller 61 is located on the upper surface of the spraying body 1. The temperature controller 61 is used to control the curing temperature of the curing heating pipe 6. The curing heating pipe 6 is used to cure and dry the coating on the barrel surface of the tower barrel body 3 after uniform spraying, which is convenient for the next polishing process of the cured barrel surface coating.

[0026] The solidified tower barrel body 3 is removed from the output pair of rollers 4. The output pair of rollers 4 also realizes the up-and-down position adjustment through the electric slide table mechanism 41, and its principle is the same as that of the input pair of rollers 2. Distance sensors 42 are installed on the side surfaces of the frames of the output pair of rollers 4. Here, the distance sensors 42 are laser distance sensors, and the laser beams emitted by them are perpendicular to the side surfaces of the frames of the output pair of rollers 4. When the distance between the upper and lower frames of the output pair of rollers 4 changes, the detected distance value of the laser distance sensor changes, and this change value is transmitted to the central control box 12. The central control box 12 controls the electric slide table mechanism 41 to adjust the distance between the upper and lower frames of the output pair of rollers 4 according to this change value, so that it keeps in contact with the upper and lower cylindrical surfaces of the tower barrel body 3, so that the tower barrel body 3 can be smoothly output from the output pair of rollers 4 and ensure the stable position of the tower barrel body 3 during the output process.

[0027] The removed tower barrel body 3 enters the inner sides of the first arched polishing frame 5 and the second arched polishing frame 51 and comes into contact with the polishing sheet 54. Under the action of the hydraulic cylinder 52, the tower barrel body 3 is polished. The piston of the hydraulic cylinder 52 is fixedly connected to the connecting plate 56. The reciprocating movement of the piston in the hydraulic cylinder 52 drives the connecting plate 56 to move left and right, so that the first arched polishing frame 5 and the second arched polishing frame 51 move back and forth on the upper and lower cylindrical surfaces of the tower barrel body 3 for polishing. And the movement speed of the hydraulic cylinder 52 can be adjusted through the central control box 12, so that the polishing speed and effect can be flexibly adjusted according to the actual polishing requirements.

[0028] Under the reciprocating push of the hydraulic cylinder 52, the first arched polishing frame 5 and the second arched polishing frame 51 polish the upper and lower cylindrical surfaces of the tower barrel body 3 through the polishing sheets 54 on the inner sides. This design enables the polishing sheets 54 to fully contact the outer cylindrical surface of the tower barrel, which is convenient for increasing the polishing area of the spraying and polishing device and improving the processing efficiency of the spraying and polishing integrated device.

[0029] During the whole process, an electric push rod 71 is fixedly embedded in the middle of the left fixing plate 11 and the right fixing plate 13. The side end of the electric push rod 71 is connected with a limit baffle 7. The side surface of the limit baffle 7 is in contact with the tower barrel body 3 through a ball 72. The electric push rod 71 is used to push the limit baffle 7 to move back and forth, so that the limit baffle 7 makes rolling contact with the front and rear cylindrical surfaces of the tower barrel body 3 through the ball 72. When the tower barrel body 3 rolls on the roller surfaces of the input pair of rollers 2 and the output pair of rollers 4, the limit baffle 7 can limit the position of the tower barrel body 3 and avoid the situation that the tower barrel body 3 deviates during the spraying and polishing processes, ensuring the stability of the spraying and polishing processes of the tower barrel body 3.

[0030] Through the collaborative work of the various components described above, the tower barrel spraying and polishing device of the present invention can effectively solve the problem in the prior art that the polishing efficiency is poor due to the small contact area between the polishing wheel and the tower barrel. It is convenient for the polishing mechanism to fully contact the outer surface of the tower barrel, increasing the polishing area of the spraying and polishing device, facilitating thorough and non-missing polishing of the tower barrel surface, ensuring that the coating on the tower barrel surface after spraying and polishing is smoother and brighter, improving the processing efficiency of the spraying and polishing integrated device, and being applicable to the tower barrel spraying and polishing device.
