The present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, only this embodiment to make the disclosure of the present invention complete and to those skilled in the art to fully understand the scope of the invention It is provided to inform you.

Figure 1 is an exploded perspective view of the coating roller according to an embodiment of the present invention, Figure 2 is a combined perspective view of the coating roller according to an embodiment of the present invention connected to the gas-liquid reservoir.

1 and 2, the application roller 300 of the present invention is coupled to the support member 310, the support member 310 is connected to the connection pipe 220 connected to the gas-liquid reservoir (100) It consists of a rolling member 320 and the coating member 330.

The support member 310 is formed to bend the hollow tube in front of the rotating shaft (310a), a plurality of supply holes 311 are formed side by side at regular intervals on the outer surface of the front rotating shaft.

The rolling member 320 has a pipe shape having a diameter of 40 to 45 mm, and a plurality of inclined communication holes 321 are formed at regular intervals along the outer circumferential surface, and the front of the support member 310. The rotating shaft 310a rotates in front of the supporting member 310 in a state in which both ends are sealed and coupled together with the coating member 330 coupled to the outside of the rolling member 320 across the center of the rolling member 320. As the 310a, the rolling member 320 rotates together with the coating member 330.

The coating member 330 has a pipe shape and is coupled to the outside of the rolling member 320 while the plurality of coating brushes 331 are tightly embedded on the outer circumferential surface.

The liquid such as paint supplied through the support member 310 by the rolling member 320 and the application member 330 coupled as described above stays in a predetermined amount in the interior space of the rolling member 320, and the inclined communication is performed. It is discharged to the coating member 330 through the hole 321 to wet the coating brush 331.

However, since the inside of the rolling member 320 is empty, paint may leak through both ends, thereby closing both ends together with the application member 330 as described above.

That is, one end of the rolling member 320 and the coating member 330 is blocked by a stopper member 350a and the other end is sequentially blocked by another stopper 350b and a sealing member 360. The front rotating shaft 310a of 310 passes through the center portion of the sealing member 360, the plug member 350b, the rolling member 320, the plug member 350a, and then passes through one end portion. The bolt is coupled to the butterfly nut of the fixing member 340 to complete the sealing of the rolling member 320 and the coating member 330.

In addition, the outer peripheral surface of the rolling member 320, as described above, the inside and the outside of the rolling member 320, the coating member in which a liquid such as paint therein is coupled to the outside of the rolling member 320 ( A plurality of inclined communication holes 321 to be properly supplied to the 330 is formed at regular intervals, the inclined communication holes 321 when the rolling member 320 is cut in the longitudinal section as shown in FIG. It looks like an impeller.

Specifically, the plurality of inclined communication holes 321 on the longitudinal section of the rolling member 320 along the outer circumferential surface of the rolling member 320 at a predetermined interval of rotation axis 310a of the support member 310 The slanted communication hole 321 is formed to be obliquely inclined toward the slant, and the inclined communication hole 321 is based on a tangent line where the center line of the inclined communication hole 321 meets the outer circumferential surface of the rolling member 320. As described above, the inclined communication hole 321 is inclined at an angle to form an impeller shape when the entire inclined communication hole 321 is viewed in the longitudinal section as described above, and the liquid such as paint flowing inside the rolling member 320 receives the least flow resistance. It is to be easily spilled to the coating member 330.

That is, when the rolling member 320 rotates in the direction of the arrow shown in FIG. 3 (the rotation direction of the rolling member 320 and the coating member 330), one of the rolling members 320 (the right side in the drawing) is raised. At this time, the liquid such as paint in the rolling member 320 does not rise along the other side, that is, in the opposite direction of rotation of the rolling member 320 (in the direction of the arrow in FIG. 3) while the liquid such as paint Through the inclined communication hole 321 formed obliquely to match the flow direction, it flows out to the outside of the rolling member 320 without flow resistance and wets the coating member 33 to the maximum, thereby allowing the user to easily apply a liquid such as paint. Will be able to.

Of course, the inclined communication hole 321 may be formed to be inclined in a free direction different from the direction shown in FIG. 3, for example, opposite to the angle of the inclined communication hole 321 of the rolling member 320 shown in FIG. 3. When the direction of rotation of the rolling member 320 will have a direction opposite to the arrow direction shown in FIG.

In general, liquids used for painting operations in the gas or liquid applied to the application roller of the present invention can be classified into water-based paints and oil-based paints. In the case of water-based paints, the flow rate is relatively low compared to oil-based paints. Although it may flow easily even though there is a flow resistance, the oil paint has a high viscosity because the flow is slow, and if there is a flow resistance may not easily flow out of the rolling member 320 compared to the water-based paint.

Therefore, in the case of the oil paint can be seen to have a greater utility to facilitate the painting work by easily flowing out through the impeller-shaped inclined communication hole 321 formed in the rolling member 320 of the coating roller according to the present invention. Of course, it has a great effect on both water paint and oil paint, but oil paint can be said to have greater utility.

It is also possible to form the inclined communication hole 321 as a curved portion having a predetermined curvature instead of the inclined communication hole 321, but in view of the machinability in view of the thickness of the rolling member 320, the inclined communication hole 321 ) Is preferably inclined obliquely as described above rather than forming the curved portion.

4 shows a cross-sectional view of the roller portion of FIG. 1.

As shown in FIG. 4, the plurality of supply holes 311 formed in the rotation shaft 310a of the support member 310 may be formed in a direction in which liquid such as paint flows in the support member 310, that is, in the drawing. The diameter of the supply hole 311 is gradually enlarged while being formed side by side at regular intervals along the direction flowing from the right to the left, such that when the diameter of the supply hole 311 is gradually enlarged, the front rotary shaft 310a of the support member 310 Since the liquid such as the paint at the right end of the inside is higher in pressure than the paint at the left end, the amount of liquid such as paint supplied to the inside of the right and left sides of the rolling member 320 through the supply hole 311 is uneven. It can prevent the failure.

That is, the diameter of the supply hole 311 formed at the right end of the rotary shaft 310a portion in front of the support member 310 is smaller, and the supply hole 311 having a larger diameter is formed toward the left side of the rotary shaft 310a portion. Thus, the right end portion where the pressure of the liquid, such as paint, is relatively larger, increases the diameter of the supply hole 311 toward the left end portion where the diameter of the supply hole 311 is smaller and the pressure of the liquid such as paint is gradually reduced. Thus, the amount of liquid, such as paint flowing through the plurality of supply holes 311 is uniform between both ends of the rolling member 320 to the paint brush 331 of the coating member 330 and The same liquid can be supplied evenly.

On the other hand, the coating roller of the present invention, as shown in Figures 2 and 4 and 5, to install the container 200 in the form of a hollow tube on the connection pipe 220 is connected to the support member 310. On the receiving container 200, the opening and closing ball valve 420 for opening and closing the liquid such as paint flowing in the connection pipe 220 and the control ball valve 420 for controlling the flow of liquid such as paint can be installed have.

Figure 5 shows a cross-sectional view of the coating roller according to another embodiment of the present invention.

The coating roller according to another embodiment of the present invention shown in Figure 5 is a configuration of the coating roller 300 of the embodiment shown in Figures 1 and 2 the configuration relating to the rolling member 320 and the coating member 320, etc. Since it is same as, the same code is given.

However, in the coating roller according to another embodiment of the present invention, the diameter of the rotating shaft 310b in front of the supporting member 310 penetrating the center of the rolling member 320 gradually increases along the flow direction of the liquid such as paint. It is configured as an enlarged shape.

Specifically, the rotating shaft 310b portion of the front side of the supporting member 310 is formed to have a relatively small diameter at the right end as shown in the drawing, and to gradually expand its diameter while proceeding to the left side of the rotating shaft 310b portion. Liquid such as paint flowing inside the support member 310 is evenly supplied into the rolling member 320 through the supply hole 311 formed as described above while expanding along the rotation shaft 310b.

At this time, the supply hole 311 may be formed in a uniform size and is formed so that the diameter is gradually enlarged along the rotation axis 310b to further supply the liquid such as paint to the rolling member 320 as described above. It can be done smoothly.

Hereinafter, the operation of the coating roller according to the present invention will be described with reference to FIGS.

The paint flowing through the support member 310 by the pumping action in the gas-liquid reservoir 100 by the user is uniformly supplied into the rolling member 320 through a plurality of supply holes 311, wherein the plurality of supply holes The diameter of the 311 is formed to gradually increase along the flow direction of the paint, or the portion forming the rotational axis 310b of the support member 310 is said to be formed so that the diameter gradually increases along the flow direction of the paint. As described above, the paint is uniformly supplied into the rolling member 320 through the supply hole 311.

On the other hand, when the user rotates the rolling member 320 in the direction of the arrow shown in Figure 3 in the process of applying paint, a plurality of supply holes 311 formed in the rotary shaft (310a) (310b) of the support member 310 Paint supplied through) flows in a direction opposite to that of the arrow in the rolling member 320.

At this time, the paint flowing in the rolling member 320 in a direction opposite to the direction of the arrow is an inclined communication hole 321 of the impeller shape in cross section, that is, the obliquely formed to match the direction in which the paint flows The paint flows easily to the coating member 330 without the flow resistance through the inclined communication hole 321, the user can apply the paint soaked in the coating brush 331 of the coating member 330 where desired. .

The user uses the opening / closing ball valve 420 to turn on / off the flow of paint at the beginning and the end of the work or whenever necessary, and the control ball valve 420 can be used to properly control the flow of paint during use. Will be adjusted.
