Description

Technical Field

[0001] This utility model relates to the field of microwave absorbing material processing technology, specifically to a microwave absorbing material impregnation processing device. Background Technology

[0002] Microwave-absorbing materials are a class of functional materials that can absorb or significantly reduce electromagnetic wave energy and reduce electromagnetic interference. They are widely used in military stealth, electromagnetic compatibility, and security protection. Impregnation is a key process in the preparation of microwave-absorbing materials. Its main purpose is to uniformly impregnate microwave-absorbing functional components (such as absorbers and resins) into fibers or substrates to form composite materials that combine structural load-bearing and microwave-absorbing properties.

[0003] When current microwave absorbing materials are impregnated in a tank, the liquid in the tank is moved out along with the material, which increases the consumption of impregnating liquid. Furthermore, there may be localized areas that are too thick and localized areas that are too thin, affecting the microwave absorbing performance. Although existing technologies include a scraper, the distance between the scraper and the material cannot be adjusted. Moreover, different microwave absorbing materials have different surface pore sizes, and the required thickness of the surface absorbing agent also varies, resulting in poor compatibility. Utility Model Content

[0004] The purpose of this invention is to provide a microwave absorbing material impregnation processing device to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for impregnating and processing microwave absorbing materials includes a frame with an impregnation tank. Multiple guide rollers are rotatably connected to the frame. A material removal mechanism is provided on the frame, including two rotating seats rotatably connected to the frame. Scrapers are detachably connected to the rotating seats, and an opening for material to pass through is formed between the two scrapers. An adjuster is provided on the frame for adjusting the distance between the scrapers and the material.

[0007] Furthermore, the regulator includes cylinders fixedly mounted on both sides of the frame, with brackets fixedly connected to the ends of the cylinders, and the brackets driving two scrapers to rotate via two transmission devices.

[0008] Furthermore, the transmission device includes a connecting rod, one end of which is rotatably connected to the end of the bracket, and the other end is rotatably connected to a fixed rod on the rotating seat. The fixed rod is fixedly arranged along the radial direction of the rotating seat.

[0009] Furthermore, the detachable connection between the rotating seat and the scraper is a bolted connection.

[0010] Furthermore, the end of the scraper is arc-shaped.

[0011] Furthermore, it also includes a sliding frame, the cylinder is fixedly connected to the sliding frame, the rotating seat is rotatably connected to the sliding frame, a slide rod is fixedly provided on one side of the frame, and a screw is rotatably provided on the other side. The sliding frame is slidably connected to the slide rod and threadedly connected to the screw.

[0012] The beneficial effects of the microwave absorbing material impregnation processing device provided by this utility model in the above technical solution are as follows:

[0013] With the designed material removal mechanism, when the material passes through the cavity between the two scrapers, the two scrapers scrape off the liquid on both sides of the material. The scraped liquid flows back into the impregnation tank under the action of gravity, reducing liquid loss. At the same time, during the scraping process, the liquid is evenly distributed along the surface of the material, ensuring the material's wave absorption performance. Furthermore, under the action of the regulator, the distance between the material and the surface can be adjusted to meet the needs of different materials.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0028] Please see Figure 1-5 An apparatus for impregnating microwave absorbing material includes a frame 1 with an impregnation tank 11. Multiple guide rollers 12 are rotatably connected to the frame 1. A material removal mechanism is also provided on the frame 1, comprising two rotating seats 2 rotatably connected to the frame 1. Scrapers 21 are detachably connected to the rotating seats 2, forming an opening 22 between the two scrapers 21 for material passage. An adjuster 3 is provided on the frame 1 to adjust the distance between the scrapers 21 and the material. The impregnation tank 11 contains microwave absorbing liquid, and the liquid level can be maintained by an external liquid delivery device.

[0029] Understandably, the line connecting the two central axes of the rotating seats 2 is perpendicular to the direction of material movement, so that the scraper can simultaneously remove liquid from both sides of the material.

[0030] The frame 1 is equipped with a roller pressing device, in which the material passes between two pressing rollers to expel the air in the pores on the surface of the material before impregnation, thereby improving the impregnation quality. This is a common technical means used by those skilled in the art, and can be implemented by those skilled in the art without creative effort to achieve the expected results.

[0031] Furthermore, the regulator 3 includes cylinders 31 fixedly mounted on both sides of the frame 1. A bracket 32 ​​is fixedly connected to the end of each cylinder 31. The bracket 32 ​​drives two scrapers 21 to rotate via two transmission devices. Each transmission device includes a connecting rod 33, one end of which is rotatably connected to the end of the bracket 32, and the other end is rotatably connected to a fixed rod 34 on the rotating seat 2. The fixed rod 34 is fixedly mounted along the radial direction of the rotating seat 2.

[0032] The cylinder 31 drives the support 32 to move. The movement of the support 32 drives the fixed rod 34 to rotate around the central axis of the rotating seat 2 via the connecting rod 33. The rotation of the rotating seat 2 drives the scraper 21 to rotate, thereby adjusting the distance between the scraper and the material.

[0033] Furthermore, the detachable connection between the rotating seat 2 and the scraper 21 is a bolted connection.

[0034] Furthermore, the end of the scraper 21 is arc-shaped.

[0035] Furthermore, it also includes a sliding frame 4, with the cylinder 31 fixedly connected to the sliding frame 4, the rotating seat 2 rotatably connected to the sliding frame 4, a sliding rod fixedly installed on one side of the frame 1, and a screw 41 rotatably installed on the other side. The sliding frame 4 is slidably connected to the sliding rod and threadedly connected to the screw 41. One end of the screw 41 passes through the frame 1 and is fixedly connected to an adjusting wheel 42.

[0036] For microwave absorbing materials, the requirements for the absorbing liquid differ between the working surface (the absorbing surface) on one side and the other side, meaning there is a difference in thickness between the two sides. By rotating the adjusting wheel 42, the screw 41 is driven to rotate. The rotation of the screw 41 causes the sliding frame 4 to move the two rotating seats 2 and the corresponding scrapers, thereby adjusting the distance between the two scrapers and the two sides of the material.

[0037] Working principle: After the adjusting wheel 42 drives the sliding frame 4 to move to the appropriate position, the cylinder 31 drives the support 32 to move. The movement of the support 32 drives the fixed rod 34 to rotate around the central axis of the rotating seat 2 through the connecting rod 33. The rotation of the rotating seat 2 drives the scraper 21 to rotate, thereby adjusting the distance between the scraper and the material, thereby scraping off the liquid on the surface of the material and making the liquid evenly distributed along the surface of the material, effectively improving the adaptability to different materials.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
