Description

Technical Field

[0001] This invention relates to the field of conveyor belt technology, specifically to a high heat-resistant and wear-resistant conveyor belt. Background Technology

[0002] Conveyor belts are industrial transport components made of rubber, fiber, metal, or plastic composites with fabrics, primarily used for carrying and transporting materials. As the core component of belt conveyors, they combine load-bearing and traction functions and are widely used in short-distance material transport. Their structure typically includes wear-resistant surface materials, a reinforcing belt core, and an anti-slip bottom material, and can be designed into specialized types such as high-temperature resistant and anti-static. Conveyor belts improve efficiency through continuous transport and adapt to diverse scenarios such as steep inclines and complex environments.

[0003] During operation, the conveyor belt experiences continuous friction with the rollers, generating heat that raises the belt temperature and affects its quality. Furthermore, this heat tends to accumulate and is difficult to dissipate, impacting the belt's lifespan. Therefore, we propose a high-heat-resistant and wear-resistant conveyor belt.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-10 This invention provides a technical solution: a high heat-resistant and wear-resistant conveyor belt, comprising:

[0034] The machine base 1 and the conveyor belt body 4 are provided. A driven support 11 is fixedly installed on the top of the machine base 1, and a driven roller 12 is rotatably connected to the inner wall of the driven support 11.

[0035] Roller cooling mechanism 2 is installed on the top of machine base 1 and is used to heat up and protect the conveyor belt body 4.

[0036] The working surface cleaning mechanism 3 is located on the top of the machine base 1 and is used to automatically clean the conveyor belt body 4.

[0037] The roller cooling mechanism 2 includes a support leg 25 and a bracket 27. The support leg 25 is fixedly installed on the top of the base 1, and a speed increaser 26 is fixedly installed on the top of the support leg 25. The bracket 27 is fixedly installed on the back of the base 1, and a wind chamber 28 is fixedly installed on the top of the bracket 27. A connecting shaft 283 is rotatably connected to the front of the wind chamber 28. The output shaft of the speed increaser 26 is fixedly connected to the end of the connecting shaft 283. A cylindrical component 284 is fixedly installed on the inner wall of the wind chamber 28, and an impeller 285 is rotatably connected to the inner wall of the cylindrical component 284. The end of the connecting shaft 283 is fixedly connected to the middle of the impeller 285. During the rotation of the driving roller 22, which drives the conveyor belt body 4, the speed increaser 26 will also be driven to work. The speed increaser 26 will drive the connecting shaft 283 to rotate rapidly, thereby driving the impeller 285 to rotate in the inner cavity of the cylindrical part 284 and generating axial thrust. This thrust can absorb cold air from the outside and then transport it to the inner cavity of the support roller 291 for cooling. The transmission ratio of the speed increaser 26 is 1:10, that is, the speed of the driving roller 22 is 450 rpm and the speed of the connecting shaft 283 is 4500 rpm. This design effectively utilizes the driving roller 22 and reduces energy waste.

[0038] In a preferred embodiment, the roller cooling mechanism 2 further includes a first support 21 and a second support 23. The first support 21 is fixedly installed on the top of the machine base 1, and a drive roller 22 is rotatably connected to the inner wall of the first support 21. The second support 23 is fixedly installed on the top of the machine base 1, and a servo motor 24 is fixedly installed on the outer wall of the second support 23. The output shaft of the servo motor 24 is fixedly connected to the end of the drive roller 22. The end of the drive roller 22 away from the servo motor 24 is fixedly connected to the input shaft of the speed increaser 26. The conveyor belt body 4 is drivenly connected to the outer walls of the drive roller 22 and the driven roller 12. By controlling the servo motor 24, the drive roller 22 can be driven to rotate on the inner wall of the first support 21, thereby driving the conveyor belt body 4 to run along a circular trajectory to transport goods. Since the end of the drive roller 22 away from the servo motor 24 is fixedly connected to the input shaft of the speed increaser 26, the speed increaser 26 can be driven to work simultaneously.

[0039] In a preferred embodiment, the conveyor belt body 4 includes a conveyor belt substrate 41, with reinforcing ribs 42 fixedly connected inside the conveyor belt substrate 41. The top and bottom of the conveyor belt substrate 41 are coated with a wear-resistant coating 43. The reinforcing ribs 42 are made of high-performance glass fiber to enhance the tensile strength of the conveyor belt body 4. The wear-resistant coating 43 is made of polyurea material to enhance the wear resistance of the conveyor belt body 4. The thickness of the wear-resistant coating 43 is 2-3 mm.

[0040] In a preferred embodiment, the top of the wind turbine 28 has a through groove 281. An air filter cover 282 is detachably connected to the top of the wind turbine 28, and a diversion pipe cover 286 is detachably connected to the back of the wind turbine 28. Branch hoses 287 are threaded onto the outer wall of the diversion pipe cover 286. Through the design of the air filter cover 282, the air absorbed inside the wind turbine 28 can be filtered to ensure the smooth flow of subsequent pipelines. The air filter cover 282 is installed on the top of the wind turbine 28 with bolts and can be disassembled for cleaning and maintenance. The number of branch hoses 287 corresponds to the number of support rollers 291. The diversion pipe cover 286 is installed on the wind turbine 28 with bolts. When the number of support rollers 291 changes during construction, the diversion pipe cover 286 with the corresponding number of branch hoses 287 can be replaced.

[0041] In a preferred embodiment, the roller cooling mechanism 2 further includes a third support base 29, which is fixedly installed on the top of the machine base 1. A support roller 291 is rotatably connected to the inner wall of the third support base 29. A rotary joint 294 is fixedly connected to the end of the support roller 291. A square tube 293 is rotatably connected to the end of the rotary joint 294 away from the support roller 291. A support arm 292 is fixedly installed at the bottom of the square tube 293. The support arm 292 is fixedly installed on the outer wall of the third support base 29. The end of the branch hose 287 is threadedly connected to the outer wall of the square tube 293. The support roller 291 is used to provide movable support for the conveyor belt body 4. The square tube 293 is rotatably connected to the end of the support roller 291 through the rotary joint 294 and its inner cavity is connected, which facilitates the heat dissipation air inside the branch hose 287 to enter the inner cavity of the support roller 291.

[0042] In a preferred embodiment, heat exchange fins 2911 are fixedly connected to the inner wall of the support roller 291, and a partition 2912 is fixedly installed on the inner wall of the support roller 291 near its end. The partition 2912 has a notch 2913. Through the design of the heat exchange fins 2911, the heat exchange speed between the air flowing inside the support roller 291 and the support roller 291 is improved. The cross-sectional shape of the notch 2913 matches the cross-sectional shape of the heat exchange fins 2911. Through the obstruction of the partition 2912, the air flowing inside the support roller 291 can flow better on the outer surface of the heat exchange fins 2911, thereby increasing the efficiency of heat removal.

[0043] In a preferred embodiment, a connecting block 295 is fixedly installed on the outer wall of the support roller 291. A connecting block 296 is detachably connected to the connecting block 295. A cover plate 297 is fixedly installed on the connecting block 296. The cover plate 297 is movably inserted into the end of the support roller 291. A circular hole 298 is provided on the cover plate 297. A welding support block 299 is fixedly installed on the inner surface of the cover plate 297. An elastic element 2991 is fixedly installed on the outer wall of the welding support block 299. A circular plate 2992 is fixedly installed on the side of the elastic element 2991 away from the welding support block 299. A rubber plate 2993 is fixedly connected to the side of the circular plate 2992 away from the elastic element 2991. 993 is in contact with the inner surface of the cover plate 297. If the inner cavity of the support roller 291 needs to be cleaned and maintained, the bolts on the connecting block 296 can be removed, and then the cover plate 297 can be pulled out from the end of the support roller 291. Then, a brush can be inserted to clean the inner cavity of the support roller 291. The elastic element 2991 is a rubber airbag. Through the elastic force of the elastic element 2991, the round plate 2992 and the rubber plate 2993 can be tightly attached to the cover plate 297 to seal the round hole 298 and achieve the function of dust prevention when idle. When air enters the interior of the support roller 291 from the other end, it can push the rubber plate 2993 as a whole to create a gap, which facilitates the discharge of hot air.

[0044] In the preferred embodiment, the working surface cleaning mechanism 3 includes a fourth support base 31, which is fixedly installed on the top of the base 1. A drive motor 32 is fixedly installed on one side of the fourth support base 31. The output shaft of the drive motor 32 extends to the other side of the fourth support base 31 and is detachably connected to an assembly shaft 33. A brush roller 34 is fixedly installed at the end of the assembly shaft 33 away from the drive motor 32. By controlling the operation of the drive motor 32, the brush roller 34 can be rotated through the transmission of the assembly shaft 33 to clean the working surface of the conveyor belt body 4. Cleaning can reduce heat accumulation and extend the service life of the conveyor belt body 4. The assembly shaft 33 is installed on the output shaft of the drive motor 32 by bolts. During maintenance, the brush roller 34 can be disassembled as a whole.

[0045] In the preferred embodiment, the working surface cleaning mechanism 3 further includes a slanted support leg 35 and a suction fan 39. The slanted support leg 35 is detachably connected to the top of the base 1. A receiving frame 36 is fixedly installed on the top of the slanted support leg 35, and a plug 37 is movably inserted into the bottom of the receiving frame 36. Through the design of the receiving frame 36, most of the impurities generated by the brush roller 34 can be received, improving the convenience of subsequent cleaning. The plug 37 is a rubber plug. Pulling the plug 37 out of the receiving frame 36 can discharge and clean the impurities inside the receiving frame 36.

[0046] In a preferred embodiment, an air filter cartridge 38 is detachably connected to the inner wall of the receiving frame 36. A suction fan 39 is fixedly installed on the top of the base 1. The air inlet end of the suction fan 39 is threadedly connected to a connecting air pipe 391. The end of the connecting air pipe 391 away from the suction fan 39 is threadedly connected to the outer wall of the receiving frame 36. The inner cavity of the air filter cartridge 38 passes through the receiving frame 36 and communicates with the inner cavity of the connecting air pipe 391. When the brush roller 34 rotates for cleaning, the suction fan 39 can be controlled to work, drawing air from the inner cavity of the air filter cartridge 38. This allows dust to be absorbed onto the outer surface of the air filter cartridge 38, reducing the harm of dust to the surrounding environment. The air filter cartridge 38 is installed on the inner wall of the receiving frame 36 with screws, allowing for disassembly and cleaning. The inclined support leg 35 is installed on the top of the base 1 with bolts, allowing for the overall disassembly and cleaning of the receiving frame 36.

[0047] Working principle: During use, the servo motor 24 is controlled to drive the drive roller 22 to rotate on the inner wall of the first support 21, thereby driving the conveyor belt body 4 to rotate along the circular track to transport goods. Since the end of the drive roller 22 away from the servo motor 24 is fixedly connected to the input shaft of the speed increaser 26, it can simultaneously drive the speed increaser 26 to work. The speed increaser 26 will drive the connecting shaft 283 to rotate rapidly, thereby driving the impeller 285 to rotate in the inner cavity of the cylindrical part 284 and generating axial thrust. This thrust can absorb cold air from the outside and then pass through the branch hose 28. 7. The square tube 293 and the rotary joint 294 are conveyed into the inner cavity of the support roller 291. During the air circulation, they exchange heat with the support roller 291, reducing the temperature of the support roller 291, which in turn reduces the temperature of the conveyor belt body 4. When the conveyor belt body 4 is running, the drive motor 32 is controlled to work, which drives the brush roller 34 to rotate through the transmission of the assembly shaft 33 to clean the working surface of the conveyor belt body 4. At the same time, the suction fan 39 is controlled to work to absorb air from the inner cavity of the air filter cartridge 38, which can then absorb dust on the outer surface of the air filter cartridge 38, reducing the harm of dust to the surrounding environment.
