Problems solved by technology

[0002] The cylindrical workpiece is a common part in machinery and chemical equipment. In order to prevent it from being corroded, the outer surface is usually sprayed with paint during the production process of the equipment. Usually, it is placed vertically, and the spray gun is manually held for spraying. The work efficiency is low, and the paint film thickness is prone to unevenness.

Embodiment 1

[0031] as attached figure 1 As shown, a spraying equipment for the outer wall of a cylinder includes a running track 2 arranged axially on the outer side of the cylinder 1, a moving seat 3 slides above the moving track 2, and a chassis 4 is fixed on the moving seat 3 , the inner end of the telescopic arm 5 is connected to the inner end of the telescopic arm 5 through a lifting mechanism, and the outer end of the telescopic arm 5 is hinged with a rotary spraying mechanism.

[0032] In the present embodiment, the bottom of the mobile base 3 is provided with a travel motor, and the power output shaft of the travel motor is connected to the travel gear 6, and the travel gear 6 is meshed with the fixed rack 7 inside the travel track 2.

[0033] Both sides of the bottom of the moving seat 3 are provided with guide grooves 8 , and the described running track 2 is provided with guide wheels 9 , and the described guide wheels 9 are placed in the described guide grooves 8 .

[0034] In...

Embodiment 2

[0053]This embodiment provides a method of spraying the outer wall of the cylinder. The method is aimed at the spraying of the frustum-shaped cylinder. The movable seat drives the nozzle to move back and forth to spray at a constant speed, and the nozzle expands and contracts at a constant speed with the diameter of the cylinder to achieve uniform spraying on the cylinder.

[0054] A method for spraying the outer wall of a cylinder in this embodiment includes a calculation method for the speed V1 of the nozzle walking, a calculation method for the speed V2 of the telescoping nozzle, and a calculation method for the rotational angular velocity V3 of the spray gun head:

[0055] 1. The calculation method of the speed V1 of the nozzle walking

[0056] First calculate the total paint consumption according to the following formula

[0057] M=S*K (1)

[0058] In the above publicity, M is the total amount of paint; S is the total area of ​​the outer wall of the cylinder, and the out...
