Description

Eco-friendly painting apparatus having double roller for anti-scattering of paint}

The present invention relates to a spraying device, and more particularly, to a painting device equipped with double rollers to prevent paint from scattering and painting paint in an environmentally friendly manner.

Currently, the spraying method using a spray gun and the roller method are mainly used for painting work. The spray gun is an airless spray tool that applies pressure to the paint itself rather than air pressure to spray and paint like mist. The roller method is a method of painting after adsorbing paint to a roller. Since the spraying method is sprayed at an appropriate distance, scattering occurs due to wind, which violates the Clean Air Conservation Act. In the spraying method, the amount of paint loss is high due to wind blowing, and paint loss and staining due to wind occur in the process of overlapping construction for uniform application. In addition, since it is sprayed like fog, it is difficult to precisely apply windows, pipes, and other irregularities.

On the other hand, in order to satisfy the Air Quality Conservation Act and avoid the problem of the spraying method, a roller method such as Korean Patent Registration No. 10-1490295 is attracting attention. However, the roller method threatens the safety of workers performing painting work, and there is a risk of an accident due to a container falling. In addition, coating through a roller has an imbalance in the thickness of the coating film, and a fatal defect such as generation of bubbles occurs. In particular, when painting the outer wall, it is very difficult to fill the grooves of the cross-sectional ribs formed by the gang form. Due to this problem, the painting process is complicated and difficult, and a lot of manpower and cost are required.

The problem to be solved by the present invention is environmentally friendly, including a double roller for preventing paint scattering, which satisfies the Atmospheric Environment Conservation Act, prevents paint scattering, and can smoothly perform painting work regardless of the shape of the object to be coated. It is to provide a coating device.

Although not shown in the drawing, a transfer pump is attached to the paint raw material container, and the paint can be supplied to the support unit 10 by pressure provided by the transfer pump. That is, the paint is supplied by pressure applied to the paint itself, not by air pressure. All known methods may be applied to the method of supplying the paint to the support part 10, and a detailed description thereof will be omitted herein.

The flow control valve 13 controls the flow rate of the paint injected into the painting unit 20 . Although the flow control valve 13 is expressed as a mechanical type, in some cases, an electronic type such as a solenoid valve may also be applied. The support 14 has a flow path through which paint flows therein. The length and diameter of the support 14 may vary depending on the purpose, structure, etc. of which the coating device 100 of the present invention is used. The injection pipe 15 extends from the support 14 and communicates with the spray tank 25 of the painting unit 20 . The injection pipe 15 may have variously deformed shapes depending on the structure of the painting device 100 . The paint flows into the spray tank 25 through the supply pipe 12, the handle 11, the support 14, and the injection pipe 15.

The painting unit 20 includes a holder 21, a double roller 22, and a spray tank 25. The cradle 21 mounts the double rollers 22 and the spray tank 25. The roller shaft 23 extending from the holder 21 is inserted into the double roller 22, and the double roller 22 rotates around the roller shaft 23. The spray tub 25 is fixed by a cover 24 coupled to the holder 21 while sealing the spray tub 25 . The shape of the cradle 21 may vary depending on the purpose, structure, etc. of which the coating device 100 of the present invention is used. In addition, the shape of the holder 21 may be manufactured in consideration of the structure and arrangement of the double rollers 22 and the spray tub 25. For example, the cradle 21 is manufactured in a curved shape, so that the effect of painting can be enhanced. In the drawings, since only one example is presented, other structures may be modified within the scope of achieving the object of the present invention.

The double roller 22 includes a pair of first rollers 22a and a second roller 22b with the jetting tub 25 interposed therebetween. That is, the spray tank 25 is positioned between the pair of rollers 22a and 22b to prevent the paint sprayed from the spray tank 25 from scattering outside the pair of rollers 22a and 22b. This will be described in detail later. The double roller 22 may be made of a material that can absorb liquid, such as a sponge, and in some cases, a material that absorbs the liquid may be included outside the double roller 22 . The first roller 22a and the second roller 22b each have a first width W1 and a second width W2. The first and second widths W1 and W2 may be the same as or different from each other. The first and second widths W1 and W2 may be adjusted according to the purpose, structure, etc. of the painting device 100 of the present invention.

FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1 . At this time, the painting apparatus 100 will refer to FIGS. 1 and 2, and detailed descriptions of overlapping parts will be omitted.

Referring to FIG. 3 , the painting part 20 includes a spray tank 25 sealed by a cover 24, a first spray nozzle 26, a lateral blocking part 27, and an upward blocking part 28. do. The spray tank 25 and at least one first spray nozzle 26 spray the paint introduced through the injection pipe 15 . The method of spraying the paint with the first spray nozzle 26 is sprayed by the pressure of the paint itself applied by the transfer pump. The first spray nozzle 26 is positioned to face an object to be coated such as an outer wall of a building. The first spray nozzle 26 makes and sprays the liquid paint into droplets of approximately several tens of μm. If the size of the droplet is too large, it is preferable to reduce the size of the droplet because it cannot fly far due to the influence of gravity. If the size of the droplet is too small, it is easily blown away by the wind, so a droplet of an appropriate size is required. All known methods may be applied to the method of spraying in the form of droplets with the pressure of the paint itself.

The first injection nozzle 26 and the pair of rollers 22a and 22b form a first distance D1, and the cover 24 and the pair of rollers 22a and 22b form a second distance D2. can In other words, the spray tub 25 is positioned inside the space provided by the double rollers 22 and spaced apart from each other by first and second intervals D1 and D2. When the spray tank 25 is located inside the double roller 22, the paint sprayed from the first spray nozzle 26 is prevented from scattering to the outside of the double roller 22. The double rollers 22 prevent loss of paint due to wind, generation of stains, etc., so as to paint more efficiently, reduce costs, and sufficiently secure aesthetics. In particular, it is an eco-friendly method that satisfies the Atmospheric Environment Conservation Act by preventing paint from scattering to the outside of the painting apparatus 100. At this time, the first and second intervals D1 and D2 may be appropriately set within a range that sufficiently achieves the object of the present invention to prevent paint from scattering to the outside of the double roller 22 .

Lateral and upward blocks 27 and 28 extend from the spray bath 25 and cover 24, respectively. The lateral blocking part 27 prevents the sprayed paint from escaping in the lateral direction, and the upward blocking part 28 prevents the sprayed paint from flying upward. To this end, the lateral blocking portion 27 and the pair of rollers 22a and 22b form a first gap G1, and the upward blocking portion 28 and the pair of rollers 22a and 22b form a second gap G1. A gap G2 may be formed. The lateral and upward blocking portions 27 and 28 prevent loss of paint due to wind, generation of stains, and the like, so as to more efficiently paint, reduce costs, and sufficiently secure aesthetics. In particular, it is an eco-friendly method that satisfies the Atmospheric Environment Conservation Act by preventing paint from scattering to the outside of the painting device 100. The first and second intervals D1 and D2 may be appropriately set within a range that sufficiently achieves the object of the present invention in preventing paint from scattering to the outside of the double roller 22 .

4 is a cross-sectional view showing a modified example of FIG. 3 . At this time, the painting unit 30 is the same as the painting unit 20 of FIG. 3 except for the second spray nozzle 31 . Accordingly, a detailed description of the overlapping parts will be omitted.

According to FIG. 4 , the painting unit 30 includes a second spray nozzle 31 disposed on the side wall of the spray tub 50 . The second spray nozzle 31 sprays paint toward the transfer roller 22 . In the process of painting, it is preferable that the transfer roller 22 absorbs the paint to an appropriate degree. When the transfer roller 22 is in a dry state, the transfer roller 22 absorbs the paint sprayed by the first spray nozzle 26 so that effective painting can be achieved. The second spray nozzle 31 controls the paint absorption state in the transfer roller 22 . If the transfer roller 22 is in a dry state, the second spray nozzle 31 sprays paint toward the transfer roller 22 so that the transfer roller 22 can absorb an appropriate amount of paint. In some cases, the spraying efficiency of the second spray nozzle 31 may be increased by the electrostatic force generated by the roller shaft 23 and the sidewall of the spray tub 25 being charged.

In the above, the present invention has been described in detail with preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. possible.
