Technical Field

[0001] This utility model relates to the technical field of spray gun paint mist control devices, specifically to a spray gun paint mist control device used for dual-gun spraying. Background Technology

[0002] Air spray guns are an important component in coating production. The working principle of a spray gun is mainly based on the interaction between compressed air and liquid. The liquid is sprayed out through the nozzle and comes into contact with atomized air to form an atomization effect, which atomizes the paint and sprays it onto the surface of the object to be coated. It plays a vital role in the coating process.

[0003] Currently, existing spray gun paint mist control devices are rudimentary and unattractive, have unstable control, are bulky, and cannot be installed in small spray booths or near robotic arms. If the installation location is too far from the spray gun, it will cause delays in paint mist control, unstable equipment quality, inconvenient maintenance, and short service life.

[0004] Based on this, the present invention designs a spray gun paint mist control device for dual-gun spraying to solve the above problems. Utility Model Content

The cabinet door 2 is fixedly equipped with an atomizing pressure gauge 5, a fan-shaped pressure gauge 6, a flow pressure gauge 7, a gun needle pressure gauge 8, and a gun needle manual pressure regulating valve 9. The right side of the stainless steel cabinet 1 is fixedly installed with an explosion-proof aviation plug 10 by hexagonal screws. Above the explosion-proof aviation plug 10, on the right side of the stainless steel cabinet 1, are two sets of spray gun atomizing control valve air pipe interfaces 11, spray gun fan-shaped control valve air pipe interfaces 12, paint flow control valve air pipe interfaces 13, and spray gun needle air pipe interfaces 14. Below the spray gun needle air pipe interfaces 14, the stainless steel cabinet 1 is located, and the stainless steel cabinet 1 is fixedly installed on the stainless steel cabinet 1.

[0022] The stainless steel cabinet 1 is internally equipped with spray gun atomization, spray gun fan and paint flow control valves 3, and each control valve 3 is equipped with an industrial display screen.

[0023] The spray gun atomization, spray gun fan shape, and paint flow control valve 3 mentioned above are all precisely controlled by a precision air pressure proportional valve, which facilitates parameterized online adjustment and pressure selection. Through the air pressure gauge on the front of the cabinet door 2 and the industrial display screen on the control valve 3, the air pressure of the spray gun and the output flow of the paint flow control valve can be monitored and controlled in real time, so as to achieve the purpose of online real-time management and control of the coating production process and quantitative adjustment of process parameters.

[0024] The spray gun atomization control valve air pipe interface 11, the spray gun fan-shaped control valve air pipe interface 12, the paint flow control valve air pipe interface 13, and the spray gun needle air pipe interface 14 are all equipped with two sets of output settings, which can control the operation of two spray guns at the same time. The main air source inlet 15 is also equipped with durable brand clamp-wall air pipe quick plugs, which can be used immediately after plugging in. The manual pressure regulating valve 9 of the needle can control the output of paint from the spray gun head.

[0025] Please refer to Figure 1 and Figure 3 The bottom of the stainless steel cabinet 1 is fixed with two support bases 4 by hexagonal screws. The two support bases 4 are symmetrically fixed to the bottom of the stainless steel cabinet 1.

[0026] The stainless steel cabinet 1 is installed on top of the support base 4. Both the stainless steel cabinet 1 and the support base 4 are made of thickened stainless steel material, which is resistant to oil stains. The support base 4 isolates the stainless steel cabinet from the spray booth floor. It can be installed on the ground or fixed to the wall, which is flexible and convenient. The installation and fixing method can be adjusted according to the actual site conditions.

[0027] Please refer to Figure 1 and Figure 4 A triangular door lock 201 is provided on the right side of the front of cabinet door 2. Sealing strips are wrapped around the four sides of the inside of cabinet door 2. Cabinet door 2 is sealed to stainless steel cabinet body 1 through the sealing strips.

[0028] A latch 101 is installed on the right side of the cabinet inside the stainless steel cabinet 1. The latch 101 is connected to the triangular door lock 201.

[0029] The triangular door lock 201 on the front of the cabinet door 2 makes it easy to open the front of the device for inspection and maintenance. The sealing strips wrapped around the four sides of the inside of the cabinet door 2 meet the relevant explosion-proof requirements and can be installed in a paint booth with a high protection level.

[0030] The working principle and usage process of this utility model are as follows: In specific use, two sets of air pipe interfaces 11 for spray gun atomization control valve, 12 for spray gun fan-shaped control valve, 13 for paint flow control valve, and 14 for spray gun needle are provided on the side of the stainless steel cabinet 1, which can realize dual-gun spraying. The spray gun paint mist control device connects to clean compressed air through the main air source inlet 15 to make the automatic air spray gun work. The control valve 3 is controlled by the precision air pressure proportional valve inside the stainless steel cabinet 1. The air pressure of the spray gun needle is adjusted by the manual pressure regulating valve 9 of the needle, which controls the output of paint from the spray gun head to the spray gun pipe. The air pressure pushes the spray gun needle out of the liquid outlet hole. At the same time, the fine hole of the spray gun cap allows the paint to be atomized and the fan-shaped surface adjusted by the compressed air to achieve the best paint mist state and achieve the best spraying effect. By using industrial displays and pressure gauges to monitor key process data in the coating production process in real time, the entire process can be controlled in a closed loop, thereby ensuring the quality stability of coating production. The compact design of the device allows the spray gun atomization control device to be installed closer to the spray gun, saving space and providing faster, delay-free control.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
