Description

Water-soluble latex spray gun

The present invention relates to a water-soluble latex spray gun, and more specifically, precise control of the amount of latex liquid and precise control of the spraying area can be performed simply and easily, and the spraying state of water-soluble latex, which has poor visibility even when sprayed on the surface of an object, can be monitored in real time. Regarding the water-soluble latex spray gun that can be confirmed, the accuracy/precision/efficiency of the work can be improved, and the quality of the work can be improved by providing a structure in which the latex liquid and air flowing into the inside are sprayed externally without mixing will be.

When it is necessary to apply water-soluble latex (for example, latex, acrylic water-based and solvent bond, etc.) to shoe uppers, bags, clothes, etc., conventionally, latex application was performed manually using a brush or brush. Latex application by manual operation significantly reduced work efficiency. In addition, since it is difficult to perform precise and uniform coating work, the work of skilled workers with long experience is required.

Accordingly, various types of spray guns capable of uniformly spraying latex or paints even by unskilled workers in various painting operations including latex coating operations have been researched and developed and provided.

Among them, the spray gun disclosed in U.S. Patent Publication No. 6,293,476 has a gun body, a spray nozzle mounted on the gun body, and an annular shape in a state surrounding the latex jet hole mounted on the gun body and installed in the spray nozzle. A configuration having an air cap forming an air blowing hole is shown. However, the spray gun disclosed in US Pat. No. 6,293,476 has a problem in that the spray nozzle is not easy to process because the shape of the spray nozzle is complicated, and also has a problem in that durability is insufficient due to severe abrasion of the valve seat.

And Japanese Patent Publication No. 2917019 and Japanese Patent Publication No. 2990604 disclose a spray gun configured to spray latex in a spray form from a latex spray unit installed on the body frame by operation of an operation member, and is attached to the spray gun Disclosed is an annular air injection device configured to spray air by being mounted on a regular basis. Here, when an annular air injection device is mounted on the spray gun and used, a covering air flow formed by spraying from the annular air injection device is sprayed from the latex spraying part of the spray gun and formed around the spray-type latex liquid. It is known that useless scattering of latex liquid, which is surrounded and becomes a factor of pollution, can be effectively suppressed.

However, in the case of using the annular air injection device as described above in the prior art, when the air is sprayed after being mounted on the body frame of the spray gun, the operation member installed separately from the operation member for latex injection of the spray gun must be operated, which causes inconvenience in use. In addition, after use, latex is often attached to the inside of the annular air jet device or spray gun, so there is inconvenience such as having to remove the attached latex.

In addition, various spray guns with improved spray performance are disclosed in Korean Patent Publication No. 1074842, Korean Patent Application Laid-Open No. 2008-103064, and Korean Patent Laid-Open No. 2011-77293.

Such a conventional spray gun is exposed to the problem of contamination by falling on the coating material when careless, remaining residual (or residual amount) around the spray nozzle of the spray gun after latex application. As latex scatters widely in the form of mist, pollution caused by dust and the problem of acting as a harmful factor to the human body were exposed.
