Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray coating apparatus for reducing splash paint generated mainly during outdoor painting work, such as a hull block shell plate, by forming an air curtain around a spray nozzle to block scatter paint and to make the coating film uniform. Provided is a spray coating device for reducing splash paint using an air curtain improved to improve painting quality.

Description

SPRAY COATING MACHINE WITH AIR CURTAIN}

The present invention relates to a spray coating device, and more particularly, by using an air curtain formed through an air spray nozzle provided while surrounding a painting nozzle, an air curtain improved to reduce scattering dust and improve painting quality is provided. It relates to a spray coating device for reducing non-acid paint used.

Spray coating is also known as spray coating and is a method developed for fast drying lacquer coating. Air spray painting has various spray patterns and has the advantage of coating by controlling the viscosity of paint in a wide range. Has the disadvantage of being lost. In addition, the paint particles temporarily remaining in the air are dried and buried on the surface of the coating, which makes the surface rough.

For spraying large structures such as hull blocks, mobile spray coating systems are generally used. Since spray painting of large structures is often performed outdoors, the phenomenon of paint blowing due to the influence of wind occurs when spray coating is performed. Such fugitive paints cause damage to not only the health of workers but also the inhabitants of the surrounding area, and cause air pollution. Therefore, there is a need for a technique capable of reducing splash paint generated during outdoor painting and improving painting quality.

The present invention has been made to solve the problems of the prior art as described above to reduce the scattering dust flying to the outside to reduce the scattering paint generated in the spray coating device and improved air curtain to improve the coating quality It is an object of the present invention to provide a spray coating device for reducing non-acid paint.

Spray coating apparatus for reducing splash paint using an air curtain of the present invention for solving the above problems is a coating nozzle for spraying the paint for painting; A plurality of air injection nozzles installed surrounding the paint nozzles to inject air for blocking the scattering of the paint sprayed through the paint nozzles; A paint supply line for supplying paint to the spray nozzle; And it characterized in that it comprises an air supply line for supplying air to the air nozzle.

At this time, the air injection nozzle is installed at regular intervals, characterized in that formed in the form of an oval with a long axis formed in the circumferential direction.

The present invention prevents the spread of paint by air curtain formed around the paint line. In addition, the fugitive paint provided by the air film is applied to the paint surface by the pressure of the paint spray to be sprayed further, thereby reducing paint loss and improving paint quality.

Hereinafter, with reference to the accompanying drawings will be described in detail the spray coating apparatus of the present invention.

1 is a schematic view showing a spray coating apparatus of the present invention.

As shown in FIG. 1, the spray coating apparatus for reducing splash paint using the air curtain of the present invention includes a coating nozzle 1, an air injection nozzle 2, a paint supply line 4, and an air supply line 5. It is configured to include).

The painting nozzle 1 plays a role of spraying paint onto a portion of the coating film 7 on the painting product 6. The coating nozzle 1 is connected in communication with the paint supply line 4, the paint supplied through the paint supply line 4 is sprayed through the paint nozzle 1 to coat the coating film 7.

A plurality of air jet nozzles 2 are fixed to the nozzle fixing part 3 while surrounding the painting nozzle 1. The nozzle fixing portion 3 is formed in a disc shape having a central opening, and the paint nozzle 1 is installed at the center thereof. Since the painting nozzle 1 and the nozzle fixing part 3 are fixedly coupled by fixing means (not shown), the painting nozzle 1 is always positioned at the center of the nozzle fixing part 3.

The air injection nozzle 2 is connected in communication with the air supply line (5). The air supplied through the air supply line 5 is injected through the air injection nozzle 2. At this time, when spraying the paint through the paint nozzle (1) to continuously spray the air through the air injection nozzle (2) to block the scattering paint.

Preferably, at least three air jetting nozzles 2 are provided, and the air jetting nozzles 2 are preferably installed at regular intervals between the air jetting nozzles 2. The air injection nozzle 2 may have a shape such as a part of a funnel whose inner diameter is reduced from the lower portion to the upper portion.

The air injection nozzle 2 may have an elliptical shape in cross section so as to surround the painting nozzle 1. That is, the air injection nozzle 2 may be formed in an elliptical structure in which a long axis is formed in the circumferential direction, thereby maximizing the scattering paint blocking effect by forming the air curtain long in the circumferential direction.

Hereinafter, a process of reducing the splash paint by the spray coating apparatus of the present invention as described above will be described.

When the operator pulls the start lever 8, air is supplied to the air supply line 5 and injected through the air injection nozzle 2. That is, the air injection by the air injection nozzle 2 is performed first. Thereafter, the paint for painting is supplied to the paint supply line 4 and sprayed through the painting nozzle 1 to the coating film 7 of the painting product 6.

When painting is completed, the operator returns the pulled start lever 8 to its original state. As a result, the injection of the paint through the painting nozzle 1 is stopped, and then the air injection through the air injection nozzle 2 is stopped.

When the paint is sprayed through the painting nozzle 1, the air is always sprayed through the air spray nozzle 2. In this way, paint spraying through the paint nozzle 1 and air spraying through the air spray nozzle 2 are simultaneously performed. As a result, a strong air curtain is formed around the paint spray to minimize dust scattering during painting. have.

The air curtain formed around the spray line prevents the splash paint bounced off the paint surface to the outside and prevents the paint from contacting the paint site. In addition, the air curtain also serves to prevent the splashing paint by blocking the outside wind.

In addition, the fugitive paint blocked by the air curtain is re-adhesive to the paint surface by the paint spray that is subsequently sprayed to reduce the amount of paint loss.

1 is a schematic view showing a spray coating device of the present invention.
