Description
Technical Field
[0001] This utility model relates to an intelligent cleaning device for belt conveyor idlers, belonging to the technical field of belt conveyor technology. Background Technology
[0002] Belt conveyors, also known as rubber belt conveyors, are commonly referred to as conveying equipment. They are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of goods. Conveying equipment includes belt conveyors, also called belt conveyors or rubber belt conveyors, which are indispensable and economical logistics conveying equipment for forming rhythmic assembly lines. Belt conveyors can be classified according to their conveying capacity into heavy-duty belt conveyors, such as mining belt conveyors, and light-duty belt conveyors, such as those used in the electronics, plastics, food, light industry, chemical, and pharmaceutical industries. Belt conveyors have the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automated operation. They use the continuous or intermittent movement of the conveyor belt to transport items weighing less than 100KG or powdery or granular materials. They operate at high speed, smoothly, with low noise, and can convey items uphill and downhill.
[0003] A belt conveyor is a friction-driven machine that transports materials continuously. It mainly consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and a transmission system. It can transport materials along a defined conveyor line from the initial feeding point to the final unloading point, creating a material transport flow. It can transport both bulk materials and packaged goods. Besides pure material transport, it can also be integrated with the technological requirements of various industrial production processes to form rhythmic assembly line transport operations.
[0004] Idler rollers are crucial components for ensuring stable long-distance transport of belt conveyors. They support the conveyor belt to bear weight, but loose materials may adhere to their surfaces. If not cleaned for a long time, the accumulated dirt on the idler rollers will accelerate belt wear, cause belt misalignment, increase running resistance, thereby reducing efficiency, increasing energy consumption, and shortening the service life of the belt conveyor. Currently, scrapers are used to clean the idler roller surfaces, but the contact force between the scraper and the idler roller is not easy to adjust, which can easily cause wear on the idler roller surface, affecting the performance of the idler roller. It is also impossible to adjust the scraper according to the amount of dirt accumulated. Utility Model Content

[0010] In this technical solution, the two ends of the side plate are bent structures, and the side plate and the three rollers are arranged in parallel. Multiple evenly distributed rotating plates are rotatably connected to the side plate. Each rotating plate is bent, and every two rotating plates are connected to the two ends of the scraper.
[0011] In this technical solution, the cleaning device is equipped with three scrapers, each of which is distributed parallel to its corresponding idler roller, and the side wall of the rotating plate is connected to the guide plate through a first spring.

[0025] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0026] like Figure 1-6 As shown, the intelligent cleaning device for the belt conveyor idler rollers includes multiple cleaning devices 20 installed on the conveyor 10. The cleaning devices 20 are evenly arranged inside the conveyor 10. The cleaning device 20 includes a bracket 21, a side plate 22, a fixing plate 23, and an air inlet pipe 24. The bracket 21 is fixedly installed inside the conveyor 10. The top of the bracket 21 is rotatably connected to the idler roller 211. The side plate 22 is fixedly connected to the side wall of the bracket 21. A rotating plate 221 is rotatably connected to the side plate 22. A scraper 222 is fixedly connected to the top of the rotating plate 221, and the scraper 222 contacts the bottom side wall of the idler roller 211. The fixing plate 23 is disposed on one side of the bracket 21. An adjustment mechanism is rotatably connected to the fixing plate 23. The adjustment mechanism is connected to the rotating plate 221. An air intake pipe 24 is fixedly installed on the top of the fixing plate 23. The air intake pipe 24 is connected to the adjustment mechanism through a branch pipe 241.
[0027] The conveyor 10 includes a support plate 11, a drive roller 12 and a belt 13 mounted on the machine body. The drive roller 12 is rotatably connected to both ends of the conveyor 10. The drive rollers 12 are connected to each other by the belt 13. The support plate 11 is disposed between two drive rollers 12.
[0028] In this technical solution, the support plate 11 is installed on the body of the conveyor 10, and the transmission roller 12 rotates on the body, which can drive the belt 13 to rotate. At the same time, the idler roller 211 on the support plate 11 can support the belt 13 to achieve stable material conveying.
[0029] The bracket 21 has a U-shaped structure and is evenly arranged inside the belt 13. Multiple brackets 21 are fixedly installed on the surface of the support plate 11. Each bracket 21 is rotatably connected to three rollers 211. The roller 211 in the middle is horizontally distributed, and the rollers 211 on both sides are inclined and symmetrical on both sides of the other roller 211. All three rollers 211 are in contact with the belt 13. An inclined guide plate 212 is fixedly installed at the bottom of the bracket 21. The guide plate 212 is located below the three rollers 211. A collection trough 213 is fixedly installed on one side of the bracket 21. The collection trough 213 is distributed corresponding to the bottom end of the guide plate 212 and is fixedly installed on the surface of the support plate 11.
[0030] In this technical solution, the inclined idler rollers 211 can ensure that the belt 13 can accommodate more material and will not fall off. The guide plate 212 is set below the idler rollers 211 to collect the scraped material and guide it into the collection trough 213 for collection, which is convenient for subsequent processing.
[0031] The side plate 22 has a bent structure at both ends. The side plate 22 and the three rollers 211 are arranged in parallel at their corresponding positions. Multiple evenly distributed rotating plates 221 are rotatably connected to the side plate 22. Each rotating plate 221 has a bent structure, and every two rotating plates 221 are connected to both ends of the scraper 222. The cleaning device 20 is provided with three scrapers 222. Each scraper 222 is distributed in parallel with its corresponding roller 211. The side wall of the rotating plate 221 is connected to the guide plate 212 through the first spring 223.
[0032] In this technical solution, the side plate 22 can be installed on the side wall of the bracket 21 to facilitate the rotation of the rotating plate 221. During daily use, the elasticity of the first spring 223 pulls the rotating plate 221 to rotate. The rotating plate 221 drives the scraper 222 to gently contact the surface of the roller 211, which can ensure the removal of easily detached foreign objects and hardly cause wear on the roller 211. Moreover, the scraper 222 effectively contacts the roller 211 at different angles to ensure the subsequent cleaning effect.
[0033] The adjustment mechanism includes a cylinder 231 and a telescopic shaft 235. The cylinder 231 is rotatably connected to the side wall of the fixed plate 23. A piston 232 is movably sleeved inside the cylinder 231. The piston 232 is fixedly connected to a pressure sensor 233, and the pressure sensor 233 is connected to the end of the telescopic shaft 235 through a second spring 234. The pressure sensor 233 is also electrically connected to an electric control valve 242. The telescopic shaft 235 is movably sleeved inside the cylinder 231. One end of the telescopic shaft 235 is rotatably connected to the middle of a connecting shaft 236, and both ends of the connecting shaft 236 are fixedly connected to a rotating plate 221. The side wall of the fixed plate 23 is provided with three cylinders 231, and the cylinders 231 on both sides are arranged at an angle.
[0034] In this technical solution, during normal use, the elasticity of the second spring 234 pushes the telescopic shaft 235 to extend, causing the connecting shaft 236 to abut against the rotating plate 221. This, in conjunction with the first spring 223, allows the scraper 222 to contact the surface of the idler roller 211. At this time, the pressure sensor 233 receives a relatively stable pressure signal. When there are many foreign objects, causing a change in the diameter of the idler roller 211, the rotation of the idler roller 211 feeds back a reaction force to the scraper 222, causing an abnormally large increase in the fluctuation amplitude of the pressure signal received by the pressure sensor 233. At this time, the pressure sensor sends a force to the cylinder 2... More positive pressure gas is supplied into cylinder 231, which pushes piston 232 to move. Piston 232 pushes second spring 234 to compress, causing telescopic shaft 235 to output greater thrust so that scraper 222 can contact idler roller 211 more closely, thereby removing stubborn stains and ensuring the cleaning effect of idler roller 211. After cleaning, the surface of idler roller 211 is clean, and the pressure signal received by pressure sensor 233 tends to be stable. At this time, the gas in cylinder 231 is discharged, and scraper 222 contacts idler roller 211 only by the elasticity of first spring 223 and second spring 234.
[0035] The intake pipe 24 is fixedly connected to three branch pipes 241 respectively. The branch pipes 241 are connected to the bottom of the cylinder 231 through a hose. Each branch pipe 241 is fixedly connected to an electric control valve 242.
[0036] In this technical solution, when controlling the air pressure inside the cylinder 231, the intake pipe 24 is connected to the air pump to keep the intake pipe 24 under positive pressure. When the pressure sensor 233 receives an abnormal signal, it controls the corresponding electronic control valve 242 to open, allowing gas to enter the cylinder 231 through the branch pipe 241. The flexible hose can be used to achieve a small-amplitude rotation of the cylinder 231.
[0037] Furthermore, the control methods and control circuits of the pressure sensor 233, the solenoid valve 242, and the air pump are not within the scope of protection of this application. Considering the actual situation, they are easy to implement, so they will not be described in detail in this application.
[0038] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
