Description

[Detailed Description of the Invention] The present invention is an improvement of a paint coating device, and relates to a rotary coating device.

When applying paint to an object to be painted, it is better to apply a thin layer of paint in multiple coats than to apply the paint to the desired thickness in one go, because it can penetrate deep into the uneven parts of the object to be painted, which has a complex shape. It can be applied evenly to achieve a stable coating film and gloss, resulting in a good finish.

However, since the conventional coating apparatus is of a fixed type, the area of the coating film becomes small and the amount of coating film increases, making it impossible to achieve the above objective.

Therefore, in the past, two spray guns were installed to increase the coating area, but it was not possible to reduce the amount of coating per application.

In this project, the spray gun is attached to the support shaft so that the angle can be adjusted.
By attaching the shaft rotatably and at a certain angle to the horizontal on the rotary disk of the drive device, and further providing a rotating body that supports the support shaft on the traveling frame, the amount of coating per coat can be reduced. To provide a rotary coating device that increases the coating area.

The present invention will be explained based on drawings of embodiments.

The support shaft 1 is supported by a rotating body 2 consisting of a universal bearing 2' at the midpoint in the axial direction, and a spray gun 4 is attached to one end of the rotating body 2 via a holder 3 whose angle can be adjusted vertically and horizontally. 360° via a swivel bearing 5 at the end
It is attached to a rotatable turntable 6 at an angle of θ (15°) with respect to the horizontal line.

This mounting angle θ may be adjusted according to the length of the support shaft as long as the spray coating from the spray gun 4 does not spread excessively.

Reference numeral 7 denotes a mounting hole provided in the rotary disk 6, through which the above-mentioned mounting angle is adjusted.

The rotary disk 6 is fixed to a speed reducer 10 to which driving force from a motor 8 is transmitted via a belt 9, and a drive device 11 is constituted by this group of devices.

The drive device 11 is fixed to a mounting frame 12, and the mounting frame 12 can slide on a rail 13.

14 indicates the object to be painted. However, first, spray gun 4
is fixed at an arbitrary angle according to the shape of the object 14 to be coated, and then the motor 8 is rotated to rotate the reducer 100-rotary plate 6, which rotates the support shaft 1, which is attached to one end. The spray gun 4 also rotates while spraying paint.

At this point, the object to be coated 14 is being conveyed in the direction of arrow A to the front of the spray gun 4 by a conveyor (not shown).

The object 14 to be coated is coated over a wide area and thinly.

In this case, the rotational speed of the spray gun 4 is used in the range of 20 to 50 rotations per minute depending on the shape of the object 14 to be coated or the conveyance speed of the conveyor.

Further, if necessary, the drive device fixed to the mounting frame 12 can be slid on the rail in the direction of arrow B and moved back and forth, thereby further expanding the coating range.

As explained above, one proposal is to attach the spray gun to the support shaft so that the angle can be adjusted, so the angle can be changed depending on the shape of the object to be coated.

Moreover, since the shaft is rotatable and attached to the drive device at a fixed angle with respect to the horizontal line, the amount of coating per coat can be reduced and the area of the coating can be increased.

Therefore, there is no need to install two spray guns,
In addition, it is possible to evenly and reliably coat objects with uneven and complex shapes, resulting in a beautiful gloss and a good finish.

Furthermore, if the rotating body is provided at the axial midpoint of the support shaft, the painting aim can be easily achieved, making the operation easier.

By combining multiple rotary coating devices of this invention, it is possible to completely coat a wide variety of objects.
