Description

Paint auto feed roller

The present invention relates to a roller for automatically supplying paint. More particularly, the present invention relates to a roller for automatically supplying paint, which automatically supplies a certain amount of paint to a paint roller for uniformly applying paint on a relatively large surface. will be.

A paint roller is a tool for painting paint by applying a paint to a roller and then rolling a roller on a surface to be painted. A paint roller, which is generally used, stores paint in a separate container, and a worker Painting is very cumbersome because you have to pick it up, soak it in a bucket, paint it on the rollers, and then pick up the rollers again and paint again. The work space is not only dirty because it is dripping down, and the worker has to repeatedly apply the paint on the rollers so that it is troublesome and difficult.

In addition, since the amount of paint on the rollers is not constant, if excessive paint is applied, there is a problem that the paint drips to the floor or flows along the surface of the paint during painting, After applying the paint and rolling the roller to some extent, the amount of paint applied to the painted surface is different so that the painted surface is not painted with uniform color and thickness, and the color and thickness of each part is different. There is a problem in the work technology to be this, except for skilled workers there is a problem that painting is difficult and difficult.

In order to solve this problem, a technology such as “Patent Roller Paint Paint Container” has been appeared. The patent discloses a paint container inside a paint adsorbent that is painted while contacting a wall. And the paint is inserted into the storage container. Since the storage container filled with paint is located at the tip of the handle, the center of gravity of the paint roller is located on the storage container side, and the worker grasps the paint roller. (把持) When the gripped part is located far from the center of gravity, it is difficult to work and also because the storage container is limited, it can not store a large amount of paint, so the paint needs to be filled frequently so work efficiency decreases. The problem is that it must be.

The present invention has been made to solve the above problems, and an object of the present invention is to store paint in a handle and a cylinder held by an operator, and then switch the controller mounted at the end of the cylinder. As the paint is automatically supplied to the roller by a certain amount as the operation is to provide an automatic paint feed roller, which allows the paint to be uniformly sprayed on all parts of the roller to paint a uniform color and thickness. .
