Description

Waterproof fluid supply roller device

The present invention relates to a waterproofing fluid supplying roller device, and more particularly, to a waterproofing fluid supplying roller device having a nozzle for automatically applying a waterproofing fluid to the roller device and spraying the nozzle from the outside and the inside of the roller.

In general, there are two methods for applying the waterproofing liquid, one using a brush (brush) or a roller, and one using a spray gun to apply the waterproofing solution to the desired area. It has been banned due to environmental pollution in accordance with the 'Air Environment Conservation Act'.

Therefore, rollers are mainly used for painting waterproofing liquid, and since they have to put the waterproofing liquid into each one and wet the waterproofing liquid before performing the painting work, the worker's fatigue increases, and the operator has to carry the waterproofing liquid container until the work is finished. also have a ham

In particular, the direction of reducing fatigue in the work process is very important because the waterproofing solution painting of a building is a factor that increases the risk of safety accidents due to an increase in working hours and fatigue of workers.

In order to compensate for the above disadvantages, a brush device for use by assembling in a spray gun has been disclosed. However, in the prior art brush device for a spray gun, the spray gun is operated in a state in which the brush is in close contact with the wall to remove the brush from the center of the brush adhering to the wall. By spraying the waterproofing liquid, the same problem as in the prior art occurs in a situation where the waterproofing liquid is scattered by natural wind.

Therefore, it is the time to need a device that allows the operator to select a spraying method according to the working environment (weather) while simply applying the waterproofing liquid through a roller, which is a basic painting equipment.
