[0034] like Figures 1 to 5 As shown together, this embodiment provides a surface spraying device for steel cylinder production, which includes a box body 1. The bottom of the box body 1 is provided with a bottle clamping mechanism for achieving limited clamping of the steel cylinder. The top of the box body 1 is provided with a rotary drive mechanism for driving the steel cylinder to rotate. The box body 1 is also provided with a spraying mechanism, which is located between the bottle clamping mechanism and the rotary drive mechanism.

[0035] The bottle body clamping mechanism includes a bearing platform 3 fixedly mounted on the bottom of the box body 1, a threaded shaft 4 is rotatably mounted on the bottom of the bearing platform 3, a first motor 5 is fixedly mounted on the bottom of the box body 1, and the output shaft of the first motor 5 is transmission-connected to the end of the threaded shaft 4 away from the bearing platform 3, a transmission ring 6 is threadedly connected to the threaded shaft 4, a clamping block 7 is provided on the bearing platform 3, and the clamping block 7 is distributed in a ring array around the transmission ring 6. The clamping block 7 is hinged to the outside of the transmission ring 6 through a connecting rod 8, and a pulley 9 is provided on the end of the clamping block 7 away from the connecting rod 8. The spraying mechanism includes a spray gun 15 fixedly mounted on the inside of the box body 1, and the spray gun 15 is arranged in a circle on the side close to the bearing platform 3. There are atomizing nozzles 16, which are all located above the supporting platform 3. The threaded shaft 4 passes through the entire transmission ring 6, and the inner side of the transmission ring 6 is provided with a thread that is compatible with the threaded shaft 4. The transmission ring 6 is connected to the clamping block 7 through a connecting rod 8. The threaded shaft 4 rotates, and the threaded transmission ring 6 moves along the axial direction of the threaded shaft 4. In the process of movement, the connecting rod 8 pulls the 7 corresponding to the connecting rod 8 to retract inward with the center of the supporting platform 3 as the center, and the pulleys 9 are close to each other to limit the gas cylinders of different sizes on the supporting platform 3, and the atomizing nozzle 16 on the spray gun 15 is used to spray the cylinders.

[0036] A bracket 2 is fixedly installed on the inner side of the box body 1, and the supporting platform 3 is fixedly installed on the bottom of the box body 1 through the bracket 2. A disc that rotates synchronously with the gas cylinder is installed on the inner side of the supporting platform 3 to avoid friction between the bottom and the supporting platform 3 when the gas cylinder rotates, and a groove corresponding to and adapted to the clamping block 7 is opened on the supporting platform 3, and a card strip is provided in the groove. When the clamping block moves on the card strip, it can not only move toward the center of the supporting platform 3 along the axial direction of the card strip, but also the height can be changed to a certain extent without leaving the supporting platform 3, so as to adapt to the downward pulling force generated by the pulling of the connecting rod 8, or a roller group is provided on the card strip to offset the downward pulling force, so that the clamping block 7 can move on the supporting platform 3.

[0037] The clamping block 7 is L-shaped, and the pulley 9 is rotatably installed on the top of the clamping block 7. The pulley 9 corresponds to the clamping block 7 one by one and is both located above the supporting platform 3. The pulley 9 can ensure that the gas cylinder can rotate on the supporting platform 3 without being tilted on the supporting platform 3.

[0038] The rotary drive mechanism includes a second motor 10 fixedly mounted on the top of the box body 1. The output shaft of the second motor 10 passes through the box body 1 and is connected to a guide rail 11. The inner side of the guide rail 11 is movably connected to a top pressure block 12, and the end of the guide rail 11 away from the second motor 10 passes through the entire top pressure block 12. The output shaft of the second motor 10 can drive the guide rail 11 to rotate and make the plugged top pressure block 12 rotate synchronously.

[0039] The guide rail 11 is threadedly connected to the top pressure block 12 through a screw rod 13. A suction cup 14 is fixedly installed on the side of the top pressure block 12 away from the guide rail 11, and the suction cup 14 is located between the top pressure block 12 and the supporting platform 3. The screw rod 13 runs through the entire top pressure block 12, and a thread corresponding to the screw rod 13 is opened on the inner side. When the screw rod 13 rotates, it moves along the guide rail 11, so that the suction cup 14 is fixed on the top of the gas cylinder, thereby driving the gas cylinder to rotate on the supporting platform 3 when the output shaft of the second motor 10 rotates.

[0040] A paint spray box 17 and a liquid pump 18 are fixedly installed on the top of the box body 1, and the paint spray box 17 is connected to the liquid pump 18 through a pipeline. A liquid guide tube 19 is provided between the liquid pump 18 and the spray gun 15. The two ends of the liquid guide tube 19 are respectively connected to the liquid pump 18 and the spray gun 15. The liquid pump 18 can extract the paint in the paint spray box 17 through the pipeline, and after being transported through the liquid guide tube 19, the rotating gas cylinder is sprayed through the spray gun 15.

[0041] When in use, the gas cylinder is placed in the box body 1 so that the bottom of the gas cylinder is located on the top of the rotatable disc in the support platform 3, and the threaded shaft 4 is taken out by the output shaft of the first motor 5 to rotate, so that the transmission ring 6 connected with the thread moves along the axial direction of the threaded shaft 4, and drives the angle of the connecting rod 8 connected with the transmission ring 6 to change, pulls the corresponding clamping block 7 on the clamping strip in the groove of the support platform 3, and retracts inward with the center of the circle of the support platform 3 as the center, and restricts gas cylinders of different sizes on the support platform 3 by the mutual approach between the pulleys 9. In this process, by rotating the screw rod 13, the threaded top pressure block 12 moves along the guide rail 11 and fixes the suction cup 14 on the top of the gas cylinder, so that when the output shaft of the second motor 10 drives the guide rail 11 and the top pressure block 12 to rotate synchronously, the gas cylinder on the supporting platform 3 can be more synchronously rotated with the disc in the supporting platform 3 under the restriction of the pulley 9, so that there is no need for workers to rotate around the gas cylinder, avoiding the entanglement of the spray pipe. At the same time, the paint in the paint spray box 17 is extracted by the liquid pump 18, and after being transported through the liquid guide pipe 19, it is atomized and sprayed through the atomizing nozzle 16 on the spray gun 15 to spray the gas cylinder rotating on the disc in the supporting platform 3, so that the spraying is more uniform and comprehensive than manual operation.

[0042] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
