In the process of painting the balloon, the fixed disk 402 drives the whole balloon to rotate around the axis of the fixed disk 402, and in order to ensure the smoothness of the rotation of the balloon, in the present embodiment, it is preferable that a rotary bearing 30 is arranged in the through hole 8 of the rotary support plate 403; the outer ring of the slewing bearing 30 is embedded in the through hole 8; through the friction force between the inner ring of the slewing bearing 30 and the balloon, the balloon is ensured to rotate along with the inner ring of the slewing bearing 30 in the rotating process, the cutting effect is not generated, and the smoothness of the integral rotation of the balloon can be effectively improved by using the slewing bearing 30; the outside limit of slew bearing 30's inner circle sets up to limit radius structure, avoids the balloon to contact with the outside limit of comparatively sharp slew bearing 30 inner circle, causes the problem of balloon explosion.
In the implementation, the control terminal 3 is preferably in the form of electronic equipment such as a tablet, a mobile phone and the like, a text writing platform is a medium such as a WeChat public number and an APP and the like, so that the control terminal is convenient for people to use, and the control terminal 3 is in data communication with the numerical control center 2 in a wireless mode; the proximity switch and the photoelectric switch 35 are both electrically connected with the numerical control center 2; the numerical control center 2 is electrically connected with a first stepping motor 401, a second stepping motor 12, a third stepping motor 1402, a fourth stepping motor 15, a fifth stepping motor 901, a sixth stepping motor, a seventh stepping motor 22, a steering engine 18 and an air pump 601 respectively.
