Abstract

PURPOSE: An automatic paint supplying rotary brush is provided to paint with uniform quality by containing in a cartridge. CONSTITUTION: An automatic paint supplying rotary brush is alternatively used with a conventional roller brush. The automatic paint supplying rotary brush comprises a device which supplies a paint by pumping when forwardly rotating a roller brush(1) and does not supply the paint or is operated in the counter direction when reversely rotating the roller brush.

Description

Automatic Paint suppling Roller Brush}

The present invention, when painting the object to be painted, such as walls, to paint the paint contained in the palette on the rotating brush to improve the productivity of the painting process by rotating the roller to paint a quick and uniform quality.

When the roller brush is pushed against the wall, when the roller brush is rotated, the paint supply pump is interlocked to continuously supply a certain amount of paint so that even non-experts can paint quickly with uniform quality.

In the past, when painting the walls of a building, it was difficult for non-experts to paint because they painted with a brush, but recently the rotating roller brush has been improved to make it easier for non-experts to paint, and because of the roller brush Productivity is also higher. However, because the roller brush is used to wet the paint once and paint it once or twice, and then the paint is put on the palette again, the experts take a lot of time, and for the non-experts, the stains are rotated once or twice with the initial soaked paint. Uniform painting, such as losing, was very difficult.

Several roller brushes have been developed to supply paint automatically.However, there is no way to supply paint consistently, and it is not compatible with existing roller brushes because it requires the use of specially designed roller brushes with holes in the rotating brush cylinder. There is no universal use.

The present invention uses an apparatus that can be used as it is without modification to the general roller brush that can be easily purchased in the existing market and installed on the rotating shaft of the roller brush so as to continuously supply a certain amount of paint. When the tricycle pin is inserted into the side of the roller brush and the roller brush is pushed against the wall, the tricycle rotates to rotate the gear pump, and the paint contained in the paint cartridge is transferred through the tube hose. It can be discharged and automatically supplied to the roller brush for painting.

In other words, without having to paint the paint on the palette, the paint is put in the cartridge, so that the painting of a certain quality while replacing the cartridge.

Install the interlocking gear pump (5) in the rotational direction on the side of the roller brush that rotates when pushed against the wall, and put the paint on the cartridges (2,18) to adjust the feed amount (8) and the flexible tube (9). And the nozzle pipe is installed in parallel with the roller brush at the discharge part of the gear pump.When the roller brush rotates, the tooth pump pumps the paint contained in the cartridge and the nozzle nozzle of the nozzle pipe It can be supplied to the roller brush through the wall paint continuously.

Since it is difficult to match the uniform paint color over a large area, the color number can be assigned to the cartridge so that the uniform paint color can be matched with a number that can identify the paint color, so that uniform painting can be performed.

When pushing and pulling the paint roller brush, a structure in which the gear pump does not reverse pumping is essential, and an expert cannot prevent the drop of paint soaked in the rotating brush.

To paint with an existing roller brush, put the paint on the palette 21 as shown in Fig. 2-1, paint the roller brush with the paint on the palette, and then paint on the wall to paint only the amount of paint on the roller brush. It took a lot of time, because the paint on the palette had to be repainted, and it took a lot of experience and skill to make the painting thickness even after the paint was applied and after rotating it several times. It was hard to do.

The present invention is to install the gear pump and the paint nozzle on the rotating shaft connected to the handle of the roller brush so as to be compatible without changing the existing paint brush, and put the standard color number paint in the cartridge, supplying the gear pump through the flexible tube The roller brush rotates one tooth of the gardenia pump with the force of the rotating force, and the interlocking gear rotates together to pump the paint, discharge a certain amount of paint through the nozzle, supply the paint to the roller brush, and do not paint the palette. You can paint with less time and less time spent painting.

Non-experts can evenly adjust the paint's density and reduce the amount of paint they use, like professionals, and professionals can improve their unit productivity, ie, paint more in the same amount of time.

In particular, if you want to paint the same color over a large area, it is difficult to match the color density of the paint, and even painting can be done using a standard color number cartridge that can be painted in the same color after the paint has dried.

Meanwhile, even when painting, it is difficult for an expert to prevent paint drops falling from the rotating brush, but the paint spill prevention device may be attached to the apparatus of the present invention to prevent paint drops falling on the floor.

Figure 3 is the structure of automatic supply of cartridge paint during roller brush rotation painting

Figure 5 is an exploded view and detailed structure of the roller brush unidirectional rotary device and fixed-value gear pump

The rotary shaft (4) connected to the handle of the roller brush is provided with a tricycle (27) that can be inserted between the groove or brush of the roller brush side portion (28) and the cylinder, and through the unidirectional rotary device (14) linked to the tricycle rotation. When the gear 15 of the gear pump 5 is rotated, another gear 6 engaged with the gear rotates in the opposite direction, sucks paint into the volume between the teeth and traps it between the teeth, After compressing the paint, it acts as a pump to discharge the paint when both teeth are out of engagement.

When the rotary brush is pushed and rotated in the forward direction, the gear pump pumps the paint by the unidirectional rotary device 14, and when the puller rotates in the reverse direction, the rotational force of the roller brush is not transmitted to the gear pump, so that the pump is reversely pumped. Prevent paint, but spread the paint on the roller brush to make the paint better and paint on the wall.

2-1 (2 input 1 output) valve (10) and locking device (11) to select and use the cartridge (18), such as a cartridge with a handle (2) and a belt-wearing type, a backpack type When the roller brush is pushed against the wall 17 through the spigot 8 and the flexible tube 9 which can push and pull the roller brush, the roller brush rotates 26 so that the gear pump 5 pumps the paint. An appropriate amount is supplied, and paint is supplied from the nozzles 12 to the roller brush 1 so that the paint 16 is uniformly buried on the wall.

In order to paint a specific color in a large area, even a professional must guess the color density by mixing paints such as red, yellow, and white paint, but if the amount of paint is left, it should be discarded. A problem arises, using a cartridge color number assigned a standard color number based on the color expressed after the paint is dried to prevent waste due to color combinations.

On the other hand, when most roller brushes are used by non-professional painters, it is not possible to prevent drops of paint from falling on the floor during painting on the wall, which is always placed under gravity under the roller brush of the present invention. By installing a scratch prevention plate to prevent the paint drops falling from the roller brush to the floor.
