Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device for a microwave absorbing coating. Background Technology

[0002] The microwave absorption principle of microwave absorbing coatings is mainly based on the energy conversion mechanism when electromagnetic waves interact with materials. High-efficiency absorption is achieved by designing material properties. There are two types of microwave absorbing coating construction: coating and patching. Coating includes two types: air pressure spraying and brushing. Air pressure spraying requires a spraying device.

[0003] The patent titled "A Coating Device for Radar Absorbing Coating" (patent application number: 202122188012.X) discloses a coating device for applying radar absorbing coatings, relating to the field of radar and its production equipment technology. It includes a coating chamber, a cleaning component on one side of the front end of the coating chamber, and a fixing component connected to the rear end of the inner side of the coating chamber via a transmission component. The cleaning component includes a water inlet pipe, a mounting pipe, and a high-pressure nozzle. The rear end of the water inlet pipe is fixedly connected to the mounting pipe via a four-way connector. The rear end of the mounting pipe passes through a fixing plate and is fixedly connected to the high-pressure nozzle. The fixing component includes a mounting block, a servo motor, and a rotating shaft. The output shaft of the servo motor is fixedly connected to the rotating shaft, and the other end of the rotating shaft is fixedly connected to the rear end face of the mounting block. By utilizing the cleaning component and the fixing component, the surface of the workpiece to be coated is cleaned by the water jet from the high-pressure nozzle. Simultaneously, the servo motor and the mounting block drive the workpiece to rotate during the coating process, improving the coating effect.

[0004] In the above-mentioned case, although the servo motor can drive the workpiece to rotate via the mounting block, improving the coating effect, it can only spray one side of the workpiece at a time, thus reducing the spraying efficiency. Furthermore, the fixed spray nozzle easily results in a small spray coverage area, leading to incomplete coating of the workpiece, which inconveniences the use of the device. Therefore, it is necessary to propose a microwave-absorbing coating spraying device to solve the above problems. Utility Model Content
