Description

TECHNICAL FIELD The present invention relates to a coating apparatus for coating chemical agents such as antistatic agents, chemicals, and other coating agents on surfaces such as floors, carpets, tatami mats, and glass. is there.

(Prior Art) Conventionally, in this type of coating, a brush is attached to a solution, the brush is taken out and rubbed on the surface to be coated, or the solution is made into a mist, and this mist is sprayed on the surface to be coated.

(Problems to be Solved by the Invention) However, in the method of applying with a brush, it is difficult and extremely laborious to form a coating film uniformly, and lacks swiftness. In addition, spraying with mist causes a very small amount of mist to hit the surface to be coated, and most of the mist scatters to the other side, using a large amount of chemical agents and other chemicals, and even adhering to unnecessary things around. Furthermore, these methods require separate drying by heating or the like, which requires a long processing time.

(Means for Solving Problems) The present invention has been made in view of this point, and a solution is continuously supplied to an application section having cushioning properties, and the application section is vibrated to apply the solution to the application section. The adhered solution is diffused by the vibration of the coating section and transferred to the surface to be coated to obtain a uniform coating film.

And its specific configuration is that the vibration driver is supported and fixed to the apparatus main body, a vibration plate supported by this vibration driver is provided, and chemical agents, chemicals, etc. are applied from a liquid tank provided in the apparatus main body or other appropriate place. A liquid pipe for passing the solution containing the agent is provided, a liquid reservoir is provided at the lower part of the vibrating plate, the tip of the liquid pipe is connected to the liquid reservoir, and a bottom plate of the liquid reservoir is provided at the lower part of the liquid reservoir. A cushion applying part made of an elastic material such as foam is provided, and a large number of small-diameter liquid flow holes are provided in the cushion applying part from the liquid reservoir side to the bottom face, and transmitted from the vibration driver to the diaphragm. By vibrating the cushion, the cushion applying section is vertically compressed and expanded, and the cushion applying section is pressed against the surface to be coated, whereby the solution in the liquid reservoir is intermittently discharged from the liquid flow hole. With That.

(Function) As a result, the solution of the coating agent enters the liquid reservoir, and the cushion coating portion is pressed against the surface to be coated by the vibration transmitted to the vibrating plate, and the solution in the liquid reservoir is cushion coated. It flows out and diffuses intermittently from a large number of liquid flow holes on the coated surface to the coated surface, spreads to every corner of the coated surface, is smoothed, and becomes uniform. Further, the water in the solution is evaporated to some extent by the pressure contact and friction of the cushion applying portion with the surface to be applied, and the applying agent is solidified. At this time as well, the cushion applying section vibrates and rubs against this coating agent, so that these coating agents adhere to the surface to be coated and are evened out.

In this way, a uniform film is formed on the surface to be coated.

(Effects of the Invention) The present invention has the above-described structure. The solution of the coating agent enters the liquid reservoir through the liquid pipe, and the solution in the liquid reservoir is cushioned by the vibration transmitted from the vibration driver to the diaphragm. By compressing and extending the coating part up and down to compress the cushion coating part on the surface to be coated, the solution in the liquid reservoir is intermittently discharged from the liquid outlet, and as a result, for example, a carpet can be applied to every corner of the surface to be coated. In the case of fibers such as the above, the solution enters into the nap and into the uneven surface, and the solution is homogenized by vibration. At that time, the vibration of the cushion applying section is also transmitted to the surface to be coated, and the adhered matters such as dirt are easily peeled off and wiped off at the cushion applying section, and the solution is transferred to the cleaned surface to form a film. Further, the permeation of the solution into these coating surfaces is rapidly performed by vibration, and the coating surface and the lower surface of the cushion coating section are heated by the friction caused by the vibration pressing of the cushion coating section, and the water content of the solution evaporates and the coating agent is evaporated. A coating film having a uniform thickness of is rapidly formed. Further, since the cushion coating portion that comes into contact with the surface to be coated moves due to the vibration, the operator can expect that the cushion coating portion will slip easily on the surface to be coated due to the pouring of the solution onto the surface to be coated. The apparatus main body can be moved with extremely small force, and the work is easy even when the coating agent is applied to a floor or the like having a large area.
