AI Technical Summary
When existing automated spraying equipment sprays wooden doors, the concentration of particles in the center of the spray head is large and the concentration of particles around is small, resulting in serious particle dissipation, causing waste and environmental pollution.
A spray device consisting of an inner spray cover and an outer sleeve cover is provided with a spray head inside the inner spray cover, a diversion valve and air pipe are provided on the outer sleeve. An air pressure sensor is formed in the air wall clamp ring gap to form an annular air wall to control the air flow and liquid flow. The paint particles sprayed by the spray head are limited to the air wall to reduce overflow.
The paint particles are sprayed more uniformly, reducing particle dissipation, and improving spraying efficiency and environmental protection.

[0014] The present invention will be further described below with reference to the accompanying drawings:
[0015] like Figure 1 As shown, a spraying device for wooden door processing comprises an inner spraying hood 2, an outer cover 1 arranged outside the inner spraying hood 2, and a wind wall annular gap 3 sandwiched between the outer cover 1 and the inner spraying hood 2;
[0016] The inside of the inner spray hood 2 is composed of several spray heads 8, and the outside of the outer hood 1 is composed of a diverter valve 5. The diverter valve 5 is a gas diverter valve. The two exhaust ports of the diverter valve 5 are respectively installed with an annular gap air pipe 6 and a nozzle main air pipe 7. The end of the nozzle main air pipe 7 extends to the inside of the inner spray hood 2 and is connected to the air inlet of the spray head 8 through a branch nozzle air pipe 12, which is convenient for providing airflow to the spray head 8. The end of the annular gap air pipe 6 extends into the annular gap 3 of the wind wall clamp, and the airflow is discharged from the annular gap 3 of the wind wall clamp to form a short-distance air wall.
[0017] An air pressure sensor 10 is installed in the wind wall annular gap 3, and a distance detector 9 is installed on the outside of the outer cover 1. The distance detector 9 is used to detect the distance from the bottom wooden door, which is convenient for adjusting the internal air pressure of the wind wall annular gap 3.
[0018] like Figure 1 As shown, the present invention also discloses the following multiple more optimized specific structures:
[0019] A main air pipe 4 is installed on the air inlet of the diverter valve 5, and the main air pipe 4 is used to connect to a pump to provide an air source.
[0020] The liquid inlet of the spray head 8 is connected to the main liquid pipe 13 through a branch liquid pipe. One end of the main liquid pipe 13 extends to the outside of the outer cover 1 to facilitate the entry of the external wooden door paint.
[0021] The outer cover 1 and the inner spray cover 2 are connected and installed together through a connecting column 11.
[0022] The distance detector 9 is fixedly mounted on the outer cover 1 via a detection frame 14 .
[0023] like Figure 1 When the spraying device shown for wooden door processing is in use, the outer cover 1 needs to be installed on a mechanical track to facilitate its forward, backward, left, right, up and down movement. The wooden door is placed below the spraying device for wooden door processing and is spaced a certain distance apart. When spraying, the air flow in the wind wall clamp annular gap 3 is ejected from the bottom to form a short-distance annular air wall. Due to the fluid flow rate, part of the paint particles sprayed from the inside of the annular air wall through the spray head 8 move toward the inner wall of the annular air wall and are confined to the inside of the annular air wall, which reduces the spillage of paint particles, reduces waste, improves the spraying environment, and avoids the problem of thick paint at the spraying center.
[0024] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
