Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a conveyor belt metal foreign object cleaning device. Background Technology

[0002] In industrial conveying scenarios such as mines, ports, and food processing, metal shavings, fragments, and other foreign objects often get mixed in during material transport, easily causing equipment wear, product contamination, and production line downtime. Traditional manual inspection is inefficient and has a high residue rate, while conventional devices suffer from incomplete cleaning and maintenance difficulties, making it difficult to meet the stringent requirements of modern production for continuity and cleanliness. Therefore, there is an urgent need for specialized conveyor belt metal foreign object cleaning devices to solve these problems.

[0003] The conveyor belt metal foreign object cleaning device mainly consists of magnets, adjustable mounting brackets, a synchronous drive mechanism, and a flow guiding and collection component. In use, the device is first fixed above the conveyor belt using the brackets. The distance between the magnetic unit and the conveyor belt surface is adjusted to ensure the magnetic field covers the material transport area. The synchronous drive mechanism is then activated to ensure the magnetic unit and conveyor belt operate at the same speed, preventing a decrease in adsorption efficiency due to relative motion. When material containing metal foreign objects passes by, the metal fragments are attracted to the surface of the magnetic unit by the magnetic force. After moving synchronously with the magnetic unit to the non-working area, the flow guiding and collection component peels off and collects the metal foreign objects, completing one cleaning cycle.

[0004] While commercially available conveyor belt metal foreign object removal devices can adsorb metal impurities, they still have significant shortcomings in practical applications. Metal foreign objects adhering to the magnet surface are difficult to clean completely; long-term accumulation affects the adsorption effect and easily leads to secondary pollution. Once the magnet loses its magnetism or is damaged, the replacement process is complex and cumbersome, often requiring professional disassembly of the entire device, resulting in long maintenance time and high costs. The conveyor belt surface remains susceptible to contamination by fine metal powder or stains, which conventional cleaning methods cannot completely remove, affecting product quality, increasing the difficulty of subsequent processing, and hindering the stable operation of the production line. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a conveyor belt metal foreign object cleaning device, which aims to improve the problems of difficult cleaning of metal foreign objects on magnets, inconvenience in replacing magnets after they lose their magnetic force or are damaged, and inconvenience in cleaning material contamination on the conveyor belt.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt metal foreign object cleaning device, comprising a housing, a rotating rod rotatably connected to the inner wall of the housing, a conveyor belt disposed inside the housing, a rotating wheel rotatably connected inside the conveyor belt, a support rod rotatably connected to the outer wall of the rotating wheel, a rotating wheel fixedly connected to the outer wall of the rotating rod, a magnet disposed on the outer wall of the rotating wheel, and a quick-release assembly disposed on the outer wall of the rotating wheel. The quick-release assembly includes a quick-release clip, the outer wall of which is fixedly connected to the inner wall of the second rotating wheel, a spring fixedly connected to the inner wall of the quick-release clip, and a pull ring fixedly connected to the outer wall of the quick-release clip.

[0007] Furthermore, a mounting plate is fixedly connected to the inner wall of the outer casing, a motor is fixedly connected to the outer wall of the mounting plate, a gear is fixedly connected to the output end of the motor, a rotating rod is rotatably connected to the inner wall of the outer casing, a gear is fixedly connected to the outer wall of the rotating rod, the gear and gear are meshed, a rack is provided on the outer wall of the gear, and a cleaning ring is fixedly connected to the outer wall of the rack.

[0008] Furthermore, the outer wall of the conveyor belt is provided with a second outer shell, and a holding plate is slidably connected to the outer wall of the second outer shell.

[0009] Furthermore, a sliding groove is fixedly connected to the outer wall of the second outer shell, and a rotating rod is fixedly connected to the sliding groove.

[0010] Furthermore, a blocking rod is fixedly connected to the inner wall of the outer shell, a scraper is provided on the outer wall of the blocking rod, and a rotating rod is rotatably connected to the outer wall of the scraper.

[0011] Furthermore, the inner wall of the quick-release clip is disposed on the outer wall of the magnet.

[0012] Furthermore, a slider is fixedly connected to the outer wall of the plate.

[0013] Furthermore, gear one is meshed with a rack, and gear two is meshed with a rack.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the magnet is driven to rotate by starting the rotating wheel, and the metal foreign objects adsorbed on the magnet are scraped off by the scraper and collected in the collection plate at the same time. With the help of quick-release clips, the magnet can be quickly replaced. This solves the problems of the magnet being difficult to remove after it has adsorbed metal foreign objects and the magnet being difficult to replace after it fails in traditional equipment. It makes up for the defects of low maintenance efficiency and cumbersome replacement operation of traditional magnets, significantly improves maintenance efficiency and simplifies the replacement process.

[0015] 2. In this utility model, the cleaning ring is driven to rotate by starting the motor. When the conveyor belt passes by, the cleaning ring simultaneously cleans the material adhering to its surface, ensuring that the conveyor belt remains clean and uncontaminated. This solves the problem of the conveyor belt being difficult to clean effectively after being contaminated with material in traditional equipment, and makes up for the shortcomings of traditional conveyor belt cleaning operations being complicated and maintenance costs being high.

The second rotating wheel 11 on the outer shell 1 rotates on the rotating rod 6, driving the magnet 2 above it to rotate and attract the metal foreign objects on the material. Then the metal foreign objects rotate to the top of the second rotating wheel 11 and are scraped off by the scraper 13, entering the holding plate 10. The scraper 13 is supported by the blocking rod 12 and the rotating rod 8. After the material is conveyed to the outer shell 7, the conveyor belt 3 is cleaned by the cleaning ring 14. The cleaning ring 14 is driven by the rack 20, and the rack 20 is then cleaned by the toothed ring. Driven by wheel 18 and gear 2 19, gear 2 19 rotates on rotating rod 3 17.
