Description

Ultra-lightweight two-component coating apparatus {Proportion type painting apparatus}

The present invention relates to an ultra-light weight two-component coating device that is portable and easy to use and increases work efficiency.

In general, the most commonly used method of painting the marine paint is an airless spray method that applies pressure to the paint to atomize it, and is a one-component pump according to the shape and performance of the equipment. It can be divided into pump and plural component pump.

The one-component pump transfers the mixed paint in a piston motion by an air motor to atomize at the end of the spray gun, and the two-component pump transfers the main material and the curing agent of the paint separately to a desired mixing ratio. By mixing in the equipment, the mixed paint is mixed using a method such as spraying, bonsai, ejection, etc., so that the components are transferred to a useful material through a process called curing and crosslinking through a chemical reaction.

A two-component coating apparatus using a dual two-component pump is disclosed in Korean Utility Model Registration No. 0276472.

Referring to FIG. 6, the conventional two-component coating apparatus includes a body 100 having an oil storage chamber so that oil is stored, a main cylinder 200 provided at the front of the body 100, and the main cylinder 200. A pair of pumps 300 and 310 to pump the main material and the curing agent introduced in accordance with the operation, the engine driving unit 400 to operate the main cylinder 200 in accordance with the power supply, and the pump ( Heater (500) (510) for maintaining the main body and the hardener pumped from the 300 and 310 at a proper temperature, and a heating hose (600) for heating and transporting the oil supplied from the heater (500) (510) ), The end of the heating hose 600 is fixed, and the main gun and the curing agent to the spray gun and the pumping machine (300,310) to be sprayed at the same time to mix the main material and the curing agent and at the same time It consists of a pair of pressurized pumps to be forcedly supplied.

The conventional two-component coating device has a limitation in that the size of equipment components is large, so that it is inconvenient to be transported and occupies a lot of installation places, so that it is almost fixedly installed and can be painted only on local parts.

In addition, even in the case of a one-component coating device, the structure is complicated and occupies a lot of volume, and since the air motor is used as the power, power is indispensable, and power supply is difficult in places where there is a limitation in use.

In addition, the edge of the current vessel is painted twice with a two-component paint, and the operator manually mixes the main material and the hardener and paints it with a brush according to the pot life. It consumes a lot of working time, and once mixed paint is cured because it is impossible to reuse, there is a problem that the paint is wasted in inefficient use of the paint.

First, the subject is stored in the subject storage space, and the curing agent is stored in the curing agent storage space, so that each can be stored in a different space to be used for a long time.

Second, since the total weight is less than 2.5kg, it is convenient to carry and use, so the work volume can be increased by about 2 times or more, so that the work efficiency is increased and the volume is small, so it is possible to work in a narrow space.

Third, the main material and the hardener are mixed and used directly at the site work location, and if there is a shortage, the main body and the hardener may be filled and used in the storage body, thereby improving the working speed.

Fourth, the mixing ratio of the main and hardeners is accurate due to constant pumping of the main pump unit and the hardener pump unit, and the mixing ratio can be adjusted by replacing the first and second cylinder housings having the first and second inner chambers with different volumes. .

Fifth, it is possible to obtain a superior two-component paint mixing effect due to the mixing nozzle.
