SU761027A1 - Apparatus for painting tube inner surface - Google Patents

Description

The invention relates to a technique of coloring the inner surface of cylindrical articles such as shells, tubes and intended for use in industries Manu- ⁵ dyaschih similar articles.

A device for coating the inner surface of pipes, comprising a spray gun mounted with the possibility of horizontal .θ ^υ VRÁTNA WHO-and-forth movement, and support rollers for accommodation of pipes, mounted on parallel horizontal shafts, one of which £ 1] is connected to a rotary drive.

A disadvantage of this device is the impossibility of painting with its help pipes with a wide range of diameters.

The purpose of the invention is the expansion of technological capabilities. ,

To achieve this goal, a device for painting the inner surface of pipes, containing a spray gun 25 mounted with the possibility of horizontal reciprocating movement, and supporting rollers for placing pipes installed on parallel horizontal layers.

2

The shafts, one of which is connected to a rotational drive, are equipped with two rollers placed on the pendulum levers, ¹ mounted on a spring-loaded axis mounted on a rack mounted with the possibility of vertical movement.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device contains a paint sprayer 1 with a rod 2, equipped with a mechanism 3 of the reciprocating motion. To accommodate the product to be painted, rubberized support rollers 4 are provided, mounted on two horizontal parallel shafts 5, one shaft with two support rollers being the lead and kinematically through a chain transmission and a gearbox connected to a drive motor 6. To hold the painted pipe on the support rollers 4 The device is equipped with two rollers 7 placed on the pendulum levers 8 mounted on a spring-loaded axis 9 mounted on the upper horizontal portion of the rack 10, which is installed 76102 7

Lena with the possibility of vertical movement. Pendulum levers can be tightened with a screw 11. Such a device allows you to hold on support rollers 4 pipes of different diameters.

The device works as follows.

The painted pipe 12 receives a rotation with a constant peripheral speed from two rubberized support rollers 4, rigidly connected with one of the shafts b, which receives rotation from the electric motor 6 through a chain transmission and a reducer.

Paint sprayer 1 with a rod. 2, moving back and forth through the mechanism 3, applies a layer of paint on the inner surface of the pipe 12. At the same time, the length of the torch remains almost constant with different diameters of the painted pipes, since the spray gun, moving back and forth, keeps a constant distance from the horizontal shafts 5.

four

The proposed device is easy to use when painting the inner surface of pipes of different diameters.

Claims (3)
