Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a shielding mesh cleaning device. Background Technology

[0002] A shielding mesh is a mesh structure used for electromagnetic / signal shielding, possessing properties such as non-magnetic properties, wear resistance, and sound insulation. The main function of a shielding mesh is to reduce external electromagnetic interference through its metallic materials (such as woven copper mesh or copper foil), protecting internal signals or equipment from interference. Shielding meshes are typically made of metal or aluminum foil, and this shielding layer effectively isolates external electromagnetic interference, improving the stability of transmitted signals. The shielding layer can be an entire outer layer or individual shielding for each pair of wires, providing different levels of protection. Shielding meshes are widely used in situations requiring reduced electromagnetic interference, such as data centers, industrial environments, and commercial buildings—places with complex electromagnetic environments. In these environments, shielding meshes effectively reduce external electromagnetic interference, ensuring complete signal transmission.

[0003] Currently, during the production and processing of existing shielding nets, a large amount of impurities or dust adhere to the surface of the net. This makes it easy for impurities or dust to get caught inside when the net is rolled up, making it difficult to clean and causing scratches on the net, which affects the quality of the product. Therefore, it is necessary to clean the woven shielding net before rolling it up to remove impurities or dust from the surface. To address this, we propose a shielding net cleaning device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution for a shielding mesh cleaning device: it includes an operating table 1, a movable plate 9, and cleaning brushes 11. A mounting frame 6 is fixedly installed at the top center of the operating table 1. Slide grooves 7 are provided at the bottom center of the mounting frame 6 and at corresponding positions at the top center of the operating table 1. Movable plates 9 are slidably arranged inside the slide grooves 7. Several cleaning brushes 11 are fixedly installed on the opposite sides of the two movable plates 9. A sleeve 14 is embedded in the inner wall of the same end of the two slide grooves 7. A movable rod 13 is slidably arranged inside the sleeve 14. One end of the movable rod 13 extends into the interior of the slide groove 7 and is fixedly connected to one end of the movable plate 9. A drive box 24 is fixedly installed at the center of one side of the operating table 1. A drive motor 18 with a drive gear 17 is fixedly installed at the center of the interior of the drive box 24. The top of the drive gear 17... The bottom is equipped with a transmission gear 16, and a push rod 15 is provided on one side of the transmission gear 16. The other end of the movable rod 13 extends into the interior of the drive box 24. The two ends of the push rod 15 are movably connected to one end of the movable rod 13 and one side of the transmission gear 16 respectively through pins. By using the movable plates 9 with cleaning brushes 11 on the operating table 1 and the mounting frame 6, which are respectively provided with opposite movable plates 9, the drive motor 18 drives the drive gear 17 to rotate, which drives the two transmission gears 16 to rotate synchronously, thereby driving one end of the push rod 15 to rotate, and causing the other end to push the movable rod 13 to move in extension and retraction, thereby driving the movable plate 9 to reciprocate linearly inside the slide groove 7. This achieves the function of reciprocating cleaning of the shielding mesh by the cleaning brush 11, achieving the purpose of efficient cleaning.

[0021] Specifically, a filter box 19 is fixedly installed at the top center of the mounting bracket 6. Two exhaust fans 21 are fixedly installed on both sides of one end of the filter box 19. Dust suction ports 20 are opened on both sides of the bottom of the mounting bracket 6. The air inlet of the exhaust fan 21 extends into the dust suction port 20 through a duct. The filter box 19 is equipped with multiple layers of filter screens 22. An exhaust port 23 communicating with the interior of the filter box 19 is fixedly installed at the top end of the filter box 19 away from the exhaust fan 21. By using the exhaust fan 21 in conjunction with the duct and the dust suction port 20, the dust raised during the cleaning process is absorbed and injected into the filter box 19. After being filtered by the filter screen 22, it is discharged through the exhaust port 23, preventing dust from falling onto the shielding screen and causing secondary pollution.

[0022] Specifically, the inner walls on both sides of the slide groove 7 are provided with limiting grooves 8, and the two sides of the movable plate 9 are fixedly provided with limiting blocks 10. The limiting blocks 10 extend into the interior of the limiting grooves 8 and slide in connection with their inner walls.

[0023] Specifically, a buffer spring 12 is fixedly installed at the end of the slide groove 7 away from the movable rod 13. The two ends of the buffer spring 12 are fixedly connected to the inner wall of one end of the slide groove 7 and the end of the movable plate 9, respectively.

[0024] Specifically, two guide rollers 5 are provided in the middle of the inner side of the operating table 1. The two ends of the guide rollers 5 are movably connected to the inner wall of the top of the operating table 1 through bearings. The guide rollers 5 are located at the bottom of the outer two sides of the mounting frame 6.

[0025] Specifically, a take-up roller 3 is mounted on one end of the top of the operating table 1 via a support frame, and a take-up motor 4 is mounted on the outside of the support frame at one end of the take-up roller 3.

[0026] Specifically, the top of the operating table 1 is provided with a feed inlet 2 at the end away from the take-up roller 3. The feed inlet 2 passes under the guide roller 5 and extends to the bottom of the take-up roller 3.

[0027] In this embodiment, during use, the woven shielding mesh enters the inner top of the operating table 1 through the feed inlet 2 and enters the inner bottom of the mounting frame 6 from below the guide roller 5, passing between the two cleaning brushes 11. At this time, the drive motor 18 drives the drive gear 17 to rotate, causing the two transmission gears 16 at the top and bottom to rotate synchronously. One side of the transmission gear 16 drives one end of the push rod 15 to make a circular motion through the pin shaft. The other end of the push rod 15 pushes and pulls the movable rod 13 to reciprocate, thereby driving the movable plate 9. The movable plate 9 makes a reciprocating linear motion inside the slide groove 7, thereby driving the cleaning brushes 11 to clean both sides of the shielding mesh, achieving the function of efficient cleaning of the shielding mesh. During the cleaning process, the mesh is lifted up. Dust is drawn in by the exhaust fan 21 in conjunction with the duct and suction port 20, and then introduced into the filter box 19. Inside the filter box 19, the dust is filtered by the filter screen 22 and then discharged to the outside through the exhaust port 23. This prevents dust from accumulating around the mounting frame 6 and causing secondary pollution to the shielding mesh. The cleaned shielding mesh is wrapped around the take-up roller 3, and the take-up motor 4 drives the shielding mesh to continuously feed, thereby achieving efficient cleaning. During the cleaning process, the movable plate 9 is limited by the limiting groove 8 and the limiting block 10 to prevent the movable plate 9 from disengaging from the slide 7, ensuring the stability of the movable plate 9 during reciprocating movement. The buffer spring 12 acts as a buffer to prevent the end of the movable plate 9 from impacting the inner wall of the end of the slide 7.
