The helmet shell is hemispherical, strong, smooth and has a certain degree of elasticity. The impact and puncture kinetic energy of the impact object are mainly borne by the helmet shell. A certain space is left between the helmet shell and the hat lining to buffer and disperse the instantaneous impact force. When producing safety helmets, a paint baking device is required to paint the safety helmets.

[0003] For example, a Chinese patent (publication number: CN204672528U) discloses a fully automatic safety helmet painting device, including an outer plate, an air nozzle, a main air duct, an upper air duct, a rotating wheel, an air nozzle air duct, an air duct pipe, a roller shaft support, a roller, a roller shaft, a blower outlet, a blower, a drive motor, a left support column, a motor support, a connecting pipe, a water mist separator, a bottom plate, a crossbeam support and a right support column. The main air duct is installed in the outer plate, the air nozzle air duct is connected to the main air duct, the air nozzle is installed on the inner side of the air nozzle air duct, the rotating wheel is installed between the two rollers, the upper air duct is provided on the roller, one end of the air duct pipe is connected to the main air duct, the other end of the air duct pipe is connected to the blower outlet, the blower outlet is installed on the blower, the blower is connected to the drive motor, and the motor support is installed at the lower end of the drive motor.

[0004] However, the above-mentioned search patent still has some shortcomings.
