Description

Technical Field

[0001] This utility model belongs to the technical field of paint spraying devices, and in particular relates to a radar-absorbing paint spraying device. Background Technology

[0002] Radar is a device that uses electromagnetic waves for detection, ranging, and positioning. It is commonly used in military, aerospace, meteorology, ship navigation, and civilian fields. To reduce signal reflection interference from radar antennas and equipment housings, and to improve and optimize the sensitivity of radar systems, radar-absorbing coatings are sprayed onto the surface of radar devices. Radar-absorbing coatings are special coatings that can suppress and attenuate electromagnetic waves. They are commonly used for stealth in military and aerospace equipment, facilities, and equipment. In order to reduce the probability of radar detection and acquisition, thereby improving the flexibility and survivability of military facilities on the battlefield, and to reduce electromagnetic wave scattering and background interference from equipment housings and scattering sources on electromagnetically compatible electronic information equipment, thereby improving the accuracy and performance of electronic equipment, radar-absorbing coatings are required on the surfaces of equipment, facilities, and components.

[0003] For example, Chinese patent document (CN220836259U) discloses a coating equipment for machining mechanical parts, including a base, a baffle, and a limiting cover. A support mechanism is provided above the base, an anti-solidification mechanism is provided inside the limiting cover, a coating mechanism is provided above the base, a recycling mechanism is provided inside the base, and a portable disassembly mechanism is provided inside the recycling mechanism. During use, this coating equipment for machining mechanical parts utilizes a stirring blade to continuously stir the coating material inside the mixing tank, ensuring the coating material is always in motion within the mixing tank and preventing it from remaining stationary. The condensation phenomenon ensures the normal feeding of subsequent spraying processes. Simultaneously, the symmetrical arrangement of several spray heads allows for multi-directional spraying of the workpiece, resulting in high spraying efficiency and uniformity. Overall, the device is quite practical. However, during use, paint dust from the spraying process can scatter in all directions, impacting the surrounding processing environment. Furthermore, for high-cost microwave absorbing coatings, this can lead to 50%-70% material spillage and waste, significantly increasing the cost of using microwave absorbing coatings. Therefore, certain improvements are needed. Utility Model Content

[0030] Detailed Implementation: First, place the device in a suitable position, then place the workpiece to be sprayed onto the spraying table. The external device delivers the radar-absorbing coating to the inside of the spraying assembly 9 through a pipeline, and sprays it onto the workpiece through the spraying assembly 9. The linear module 6 drives the spraying assembly 9 to move laterally to spray the workpiece comprehensively, preventing spray dead zones. The fan 402 is started. The fan 402 extracts most of the coating dust generated during the spraying process through the exhaust pipe 403, three-way valve, pipeline, the inner cavity opened inside the exhaust pipe 403, and the exhaust port 406, reducing the dispersion of coating dust and facilitating the collection and reuse of the dispersed coating. The extracted paint dust and gas are transported to the first chamber 408 through the exhaust pipe 407. The filter 409 filters the gas entering the first chamber 408. The filtered gas is then transported to the second chamber 414 through the exhaust pipe 411, the third chamber 502, the connecting pipe 412, the pipe joint, and the connecting pipe. The filtered gas is then transported to the area below the linear module 6 through the exhaust port 404, forming an air curtain below the linear module 6 to prevent small amounts of drifting paint dust from adhering to the surface of the linear module 6. This prevents the paint dust from affecting the smooth operation and service life of the linear module 6, thereby effectively improving the protective effect of the device during use.

A third cavity 502 is provided inside the connecting box 501. The two sides of the third cavity 502 are respectively connected to the exhaust pipe 411 and the connecting pipe 412. An inclined blade 503 is provided inside the third cavity 502. A rotating shaft 504 is fixedly connected inside the inclined blade 503. The bottom end of the rotating shaft 504 extends into the mounting box 401 and is fixedly connected to a reciprocating screw. The rotating shaft 504 is rotatably connected to the mounting box 401 and the connecting box 501. A threaded sleeve 505 is threadedly connected to the reciprocating screw. The threaded sleeve 505 is rectangular, and the bottom of the threaded sleeve 505 extends into the first cavity 408 and is fixedly connected to a cleaning block 506. The cleaning block 506 is located on one side of the filter screen 409. The threaded sleeve 505 is slidably sealed inside the mounting box 401.

[0032] Detailed implementation: The gas flowing inside the third chamber 502 drives the inclined blades 503 to rotate. Utilizing the linkage effect between the inclined blades 503 and the rotating shaft 504, power is transmitted to the rotating shaft 504, causing the rotating shaft 504 to drive the reciprocating screw to rotate. Then, utilizing the linkage effect between the reciprocating screw and the threaded sleeve 505, power is transmitted to the threaded sleeve 505, causing the threaded sleeve 505 to drive the cleaning block 506 to move downwards. The cleaning block 506 cleans the surface of the filter screen 409 to prevent the filter screen 409 from becoming clogged, thereby preventing any impact on the filtration effect and protective performance of the device. The cleaned dust enters the collection box 410 for collection, thus effectively improving the operational stability of the device during use.

[0033] Working Principle: During use, first place the device in a suitable position, then place the workpiece to be sprayed onto the spraying table. The external device delivers the radar-absorbing coating to the spraying assembly 9 through a pipe, and sprays it onto the workpiece. The linear module 6 drives the spraying assembly 9 to move laterally for comprehensive spraying of the workpiece. The fan 402 is activated, and through the exhaust pipe 403, three-way valve, pipe, the internal cavity of the exhaust pipe 403, and the exhaust port 406, most of the coating dust generated during the spraying process is extracted. The extracted coating dust and gas are then transported to the first chamber 408 through the exhaust pipe 407. The filter 409 filters the gas entering the first chamber 408, and the filtered gas is then transported through the exhaust pipe 411 and the third... The gas is transported from cavity 502, connecting pipe 412, pipe fitting, and connecting pipe to the second cavity 414. The filtered gas is then transported to the area below the linear module 6 through the air outlet 404, forming an air curtain below the linear module 6 to prevent small amounts of drifting paint dust from adhering to the surface of the linear module 6. The gas flowing inside the third cavity 502 drives the inclined blades 503 to rotate. Utilizing the linkage effect between the inclined blades 503 and the rotating shaft 504, power is transmitted to the rotating shaft 504, causing the rotating shaft 504 to drive the reciprocating screw to rotate. Then, utilizing the linkage effect between the reciprocating screw and the threaded sleeve 505, power is transmitted to the threaded sleeve 505, causing the threaded sleeve 505 to move the cleaning block 506 downwards. The cleaning block 506 cleans the surface of the filter screen 409, making it convenient to use.
