In the above, we looked at the basic configuration of the two-component coating device of the present invention.

A two-component coating device according to an embodiment of the present invention may be provided to further include the following components.

Figure 3 is a cross-sectional view showing a main transfer line, a hardener transfer line, and a power supply line according to an embodiment of the present invention, and Figure 4 shows a state in which the main body and the hardener body of Figure 3 are separated from the main body. This is a cross-sectional view.

Referring to Figures 3 and 4, the two-component coating device of the present invention may further include a controller.

The present invention may further include a main transfer line 20 connecting the main tank 121 and the mixer 111, and a curing agent transfer line 30 connecting the hardener tank 131 and the mixer 111.

First, the subject transfer line 20 is connected to the subject tank 121 and is partially embedded in the subject body 120, the first subject transfer line 21, and the end of the first subject transfer line 21. It consists of a second main transfer line (22) that is extended and partially embedded in the main body (110) and connected to the mixer (111).

The first main transfer line 21 and the second main transfer line 22 may be arranged to be coupled and disengaged as the main body 120 and the main body 110 are attached and detached.

Next, the hardener transfer line 30 is connected to the hardener tank 131 and is partially embedded in the hardener body 130. It consists of a second curing agent transfer line 32 that is extended and partially embedded in the main body 110 and connected to the mixer 111.

The first curing agent transfer line 31 and the second curing agent transfer line 32 may be provided to be coupled and disengaged as the curing agent body 130 and the main body 110 are attached and detached.

Here, the above-described main transfer line 20 and the hardener transfer line 30 are coupled to the main tank 121 and the hardener tank 131 by applying the structure of a high pressure hose and a Camlock type hydro-pneumatic coupling. and may be provided for easy separation.

As the two-component coating device of the present invention discussed above is equipped with the main transfer line 20 and the hardener transfer line 30 described above, the main agent and the hardener can be transferred and mixed through the following path.

First, the hardener stored in the base tank 121 is transferred to the mixer 111 of the main body 110 through the base transfer line 20, and the hardener stored in the hardener tank 131 is transferred through the hardener transfer line 30. It is transferred to the mixer 111 of the body 110.

The base material and hardener transferred in this way are mixed based on a preset mixing ratio through the mixer 111, and at this time, the mixing ratio of the paint can be controlled by the above-described controller 112 provided in the main body 110. .

Afterwards, the mixed paint may be prepared to flow from the mixer 111 to the sprayer along the spray line and be sprayed to the outside through a spray gun.

The internal structure of the mixer 111 and the injector is well known to those skilled in the art, so detailed description will be omitted.

As the two-component coating device of the present invention adopts this transfer and mixing structure, the base material and hardener are mixed only inside the mixer 111, so the paint mixed in real time can be consumed immediately, thereby reducing the amount of waste paint. It has the effect of minimizing environmental pollution.

In addition, as the main transfer line 20 and the hardener transfer line 30 of the two-component coating device of the present invention are provided in a form embedded in each body as described above, the paint transfer path can be simplified, and the paint transfer path can be simplified. This has the effect of effectively organizing and managing the transfer line within the device.

In addition, unlike the prior art where the paint tank is replaced by emptying the tank, cleaning it, and then injecting new paint, the present invention allows the paint tank itself to be replaced and can be simply cleaned by adding a cleaning solvent to the transfer line. Therefore, it has the advantage of saving time and cost.

Furthermore, the present invention may further include a power supply line connecting the main body, the main pump provided in the main body, and the curing agent pump provided in the hardener body, respectively.

Figure 5 is an enlarged cross-sectional view of a power supply line according to an embodiment of the present invention.

3 to 5, the power supply line 40 includes corresponding power connectors embedded in each coupling surface of the main body 110, the main body 120, and the hardener body 130. can do.

The above-described power connector may be provided to be fastened to each other as the main body 110, the main body 120, and the hardener body 130 are combined, and at this time, the coupling surface of each body on which the power connector is formed Corresponding coupling grooves or coupling protrusions may be formed to guide coupling between each body.

At this time, the power may be automatically turned on and off according to the coupling and disengagement of the power connector. Accordingly, the main pump 122 and the curing agent pump 132 are operated only when each body part is completely coupled. This becomes possible.

Through this, it is possible to prevent paint from being lost to the outside of the device or problems occurring in the mixing of the mixed paint as the transfer of the base material or hardener begins when the device is not fully coupled, making the product more stable. There is an effect of operating the two-component coating device of the invention.

One end of the power supply line 40 may be connected to equipment such as a pump provided in the main body 120 or the hardener body 130, and the other end may be connected to the power supply device 113.

Most of these power supply lines 40 can be provided in a structure that is embedded along the frame of each body, and as a result, the durability of the power supply line 40 is improved and at the same time, the wiring leading out to the outside is eliminated, so management is possible. It is very easy to use and has the effect of improving space utilization.

In the drawing, the power device 113 is shown as being provided inside the main body 110, but this shows one embodiment of the present invention and is not limited thereto, and the power device 113 is installed inside the main body 110. It may also be provided separately outside of .

When the two-component coating device of the present invention adopts the configuration of the power supply line 40 described above, the arrangement and management of the power supply line 40 connected to the power supply device 113 becomes easy, and space utilization is remarkable. There is a significant upward effect.

The components for each body described above describe an embodiment of the present invention, and the arrangement of the components is not limited thereto, and may be arranged in various ways as needed and may be used selectively as needed.

Furthermore, the two-component coating device according to an embodiment of the present invention can be provided so that it can be arranged in various ways as follows.

Figures 6 and 7 are plan cross-sectional views showing the arrangement structure of a two-component coating device according to an embodiment of the present invention.

Referring to FIG. 6, a second main transfer line 22 connected to the first transfer line 21 is provided on the first and second surfaces of the main body 110, and the third and fourth surfaces A second hardener transfer line 32 connected to the first hardener transfer line 31 may be provided.

At this time, the second transfer line 22 and the second hardener line ( 32) As the base material and hardener can be transferred only through this system, stable operation of the device becomes possible.

Next, referring to FIG. 7, the power supply line 40 connected from the power supply device 113 is provided on all of the first to fourth surfaces of the main body 110, and the main pump 122 and the curing agent pump ( 132) and can be connected through various arrangement structures.

That is, the main body 110, the main body 120, and the hardener body 130 may be arranged to be combined in various structures such as 'ㄱ' and 'ㄴ' rather than in a line.

Accordingly, work can be done by easily combining the main body 110, the main body 120, and the hardener body 130 even in a narrow work space, which has the advantage of significantly increasing the usability of the work environment.

At this time, the power may be automatically turned on and off according to the coupling and disengagement of the power connector. Accordingly, the main pump 122 and the curing agent pump 132 are operated only when each body part is completely coupled. By doing so, there is an effect of further improving work stability.

In addition, the two-component coating device according to an embodiment of the present invention may be provided to further include the following additional components.

The two-component coating device of the present invention further includes a U-shaped hose hanger provided on one side of the main body and the hardener body to further facilitate the organization and management of paint transfer hoses such as the main transfer line and the hardener transfer line. It can be included.

At this time, the paint transfer hose may be provided in the form of a constant temperature transfer hose as shown below to maintain temperature in winter or low temperature environments.

Paint transfer hoses using the existing heating coil method have the risk of explosion by reacting with volatile organic solvents generated during painting work, and there have been cases of malfunction of the constant temperature function when an electrical short occurs.

However, the constant temperature transfer hose of the present invention significantly improves the thermal insulation function by covering the main hose, hardener hose, hot water hose (input and output), and cleaning hose with a material with high flexibility and thermal insulation performance to maximize thermal insulation performance. It has the advantage of preventing a decrease in work performance due to an increase in the viscosity of the paint in a low-temperature environment.

The constant temperature transfer hose combines a small hose through which hot water flows adjacent to the main body and the hardener hose to maintain constant temperature but eliminate the risk of explosion or malfunction of the constant temperature function due to electrical problems. A hot water line is installed and paint is transferred. Provision may be made to surround the hose with insulation.

The constant temperature transfer hose of the present invention provided in this way can be provided with a coating material with flame retardant performance as the outermost cover material to prevent fires caused by welding defects (spatter) or sparks generated during peripheral welding or cutting work.

At this time, in the case of the outermost flame retardant coating, it can be provided in an easily attachable and detachable form of Velcro type to facilitate partial repair in case of hose damage, and in the case of the inside of the flame retardant coating, a flexible insulating material can be applied.

In addition, the two-component coating device of the present invention may further include an air lock lever.

The air lock lever may be installed on the pneumatic lines flowing into the main tank and the hardener tank, and may be provided to stop air from flowing into the main tank and the hardener tank in the event of an emergency.

In addition, the two-component coating device of the present invention may further include a paint mixing check valve.

In the conventional case, the mixing ratio was determined by measuring the amount of subject and hardener transferred from the equipment by weight ratio after separating the spray gun in a work environment where paint spraying work was in progress.

However, when the main body of the two-component painting device of the present invention is equipped with a paint mixing check valve, it has the advantage of being able to immediately check the paint mixing ratio on the device.

The description of the above-mentioned air lock lever and paint mixing check valve is provided as an example of the present invention to be operated manually by an operator, but it is not limited thereto, and an electrically operated valve such as a solenoid valve may be used. .

As discussed above, using the two-component coating device according to an embodiment of the present invention can provide the following advantages.

In the case of a conventional two-component painting device, there are many internal components required to transport and mix two different paints, the paint movement passage is made of high-pressure piping, so position adjustment between components is not possible, and the paint is heavy and has a thick diameter. There was a problem in that it was difficult to effectively organize and manage the transfer hose.

In particular, it adopts a structure in which major equipment such as the main pump (main pump and hardener ratio adjustment device), main pump, hardener pump, heater for maintaining the appropriate temperature of the paint, and water pump for cleaning are mounted as an integrated unit within a single body. , there have been disadvantages in that it is impossible to move or detach the equipment and there are many limitations in securing space.

In addition, different types of paints could not be replaced and used immediately, and there was a long waiting time between emptying the base and hardener tanks, cleaning them, and then injecting and using new paints, which resulted in work inefficiencies.

The two-component coating device of the present invention was designed to solve this problem, and is composed of a detachable main body, a main body, and a hardener body, and separate and arranges equipment such as a pump, storage tank, and mixer according to function. It is characterized by

In addition, by providing a means of movement at the bottom of each body, the body can be separated and moved while equipped with equipment.

Accordingly, when replacing equipment, if the distance between the two-component coating device and the supply point is long, there is no need to transport the object to be replaced to the work site. Instead, the main body or hardener body can be separated from the main body and moved to the supply point. Replacement becomes possible.

In particular, when replacing a paint tank, it took a long time to empty the base and hardener tank, clean it, and then inject and use a new paint. However, as the paint tank itself can be replaced immediately, the time is reduced. There is a saving effect.

In addition, as conventional complex wiring such as the main transfer hose, hardener transfer hose, and power supply hose are buried inside each body, organization and management become very easy, and space utilization can be significantly improved. has
