Description

Technical Field

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

[0002] A conveyor belt is a device used to transport materials. There are many types of conveyor belts, and conveyor belts made of different materials have different effects. Among them, polyester conveyor belts are a common type of conveyor belt. They are usually made of polyester fiber (PET). Polyester fiber has high tensile strength, so polyester conveyor belts usually have good tensile properties and are suitable for long-distance and high-load conveying tasks. Conveyor belts need to be used in conjunction with components such as drive units, conveyor shafts, idlers, and tensioning devices. After long-term use, cracks will appear on its surface, which will affect its tensile strength. In order to ensure its tensile strength, vision sensors are usually used for detection.

[0003] However, when existing tensile-resistant conveyor belts are in use, cracks on the conveyor belt surface are not easily detected by visual sensors due to impurities and other factors, thus affecting their tensile resistance. In addition, the coating on the conveyor belt surface will also be worn down during use, which will also affect its tensile resistance.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Please see Figures 1-12The diagram illustrates a stretchable conveyor belt, comprising a conveyor belt body 1, a conveyor shaft 11, and a base plate 12. Two U-shaped plates 15 are connected to the lower part of the conveyor belt body 1 via a first pushing mechanism. A first conveying roller 16 is rotatably connected to the side wall of each U-shaped plate 15 via a first rotating shaft. A first connecting block 17 is fixedly connected to the side wall of each U-shaped plate 15, and a fixing cover 18 is fixedly connected to the side wall of the first connecting block 17. The fixing cover 18 is fitted onto the side wall of the first conveying roller 16. A moving block 27 is connected to the fixing cover 18 via a first moving mechanism. A vision sensor 28 is fixedly connected to the bottom of the moving block 27. The vision sensor 28, located inside the fixing cover 18, reduces the influence of external light and improves the accuracy of the detection results. Furthermore, a cleaning mechanism for cleaning the surface of the conveyor belt body 1 is provided on the side wall of the first connecting block 17. A bracket 26 is fixedly connected to the top of the base plate 12, and two symmetrically arranged coating covers 19 are fixedly connected to the side wall of the bracket 26. A feeding port 20 is fixedly connected to the side wall of each coating cover 19, and a sponge block 21 is fixedly connected to the opposite side wall of the two coating covers 19. A sliding plate 29 is slidably connected inside each coating cover 19 through a second pushing mechanism, and a flow regulating mechanism is provided inside the coating cover 19. A conveying mechanism for conveying the conveyor belt body 1 is provided at the top of the base plate 12, which facilitates the detection of cracks on the surface of the conveyor belt body 1, and at the same time facilitates the cleaning of the surface and cracks of the conveyor belt body 1, ensuring the accuracy of the detection and improving its tensile strength. It can automatically coat the surface of the conveyor belt body 1 with a coating to improve wear resistance, anti-slip and anti-aging properties, thereby indirectly improving the tensile strength of the conveyor belt body 1.

[0033] The first pushing mechanism includes a first L-shaped plate 201 fixedly connected to the top of the base plate 12, and a first fixing tube 205 fixedly inserted into the top of the first L-shaped plate 201. A first connecting plate 202 is fixedly connected to the side wall of each U-shaped plate 15, and two symmetrically arranged first guide rods 206 are fixedly connected to the opposite side walls of the two first connecting plates 202. The first guide rods 206 are inserted into the first fixing tubes 205, and a guiding mechanism is provided between the two first connecting plates 202. An L-shaped tube 207 is fixedly connected to the side wall of the first fixing tube 205, and a tool is fixedly connected to the upper end of the L-shaped tube 207. The working cylinder 208 is filled with hydraulic oil, and a counterweight plate 209 is slidably connected inside the working cylinder 208. When the conveyor belt body 1 is conveying, it can slide on the surface of the first conveyor roller 16. Under the gravity of the counterweight plate 209, the hydraulic oil can be squeezed, thereby pushing the two first guide rods 206 to move away from each other. At the same time, the two first conveyor rollers 16 are driven to move away from each other through the first connecting plate 202 and the U-shaped plate 15, thereby applying a compressive force to the conveyor belt body 1, causing the conveyor belt body 1 to be squeezed and bent, which facilitates the exposure of cracks.

[0034] The guiding mechanism includes two symmetrically arranged first T-shaped guide rods 203, with the lower end of the first T-shaped guide rod 203 fixed to the top of the lower first connecting plate 202. The upper first connecting plate 202 is sleeved on the side wall of the first T-shaped guide rod 203. A second connecting block 204 is sleeved on the side wall of each first T-shaped guide rod 203, and the second connecting block 204 is fixed to the side wall of the first L-shaped plate 201, thus guiding the movement of the two U-shaped plates 15.

[0035] The cleaning mechanism includes two hollow movable plates 301, which are connected to the movable block 27 via a reset mechanism. Multiple bristles 302 are fixedly connected to the side wall of the movable plate 301 near the conveyor belt body 1, and multiple air extraction holes 303 are provided on the side wall of the movable plate 301 near the conveyor belt body 1. A first U-shaped tube 304 is fixedly connected between the two movable plates 301, and an air extraction pipe 306 is fixedly inserted into the top of the fixed cover 18. A first flexible hose 305 is fixedly connected between the air extraction pipe 306 and the first U-shaped tube 304. The fixed cover 18 has two opposite side walls with... The system has multiple arrayed air inlets 307, and the sidewalls of the air inlets 307 can be equipped with filters. During detection, when the moving block 27 moves, the moving plate 301 and the brush bristles 302 can be moved by the reset mechanism. At this time, the brush bristles 302 can clean the impurities on the surface of the conveyor belt body 1 and in the cracks. At the same time, the exhaust pipe 306 is connected to the external exhaust equipment for exhaust operation. At this time, the impurities on the surface of the conveyor belt body 1 and in the cracks can be absorbed through the exhaust holes 303, thereby ensuring the accuracy of the detection results of the vision sensor 28.

[0036] The second pushing mechanism includes a second L-shaped plate 401 fixedly connected to each coating cover 19, and a second fixing tube 402 fixedly inserted into the side wall of the second L-shaped plate 401. A second guide rod 403 is inserted into the second fixing tube 402 and extends through the coating cover 19 and is fixed to the sliding plate 29. A second U-shaped tube 404 is fixedly connected between the two second fixing tubes 402, and a second hose 405 is fixedly connected between the second U-shaped tube 404 and the L-shaped tube 207. When the counterweight plate 209 squeezes the hydraulic oil, it can push the two second guide rods 403 to move closer to each other, thereby pushing the sliding plate 29 to move closer to the adjusting plate 24, which can squeeze the coating in the coating cover 19.

[0037] The flow regulating mechanism includes a first fixed plate 22 fixedly connected inside the coating cover 19, and the first fixed plate 22 has a plurality of arrayed first through holes 23. An adjusting plate 24 is inserted into the side wall of the coating cover 19 and slides on the first fixed plate 22. The adjusting plate 24 has a plurality of arrayed second through holes 25. The side wall of the coating cover 19 is provided with a second moving mechanism for moving the adjusting plate 24. The adjusting plate 24 is moved by the second moving mechanism. When the adjusting plate 24 moves, the overlapping area between the second through holes 25 and the first through holes 23 can be adjusted, thereby adjusting the flow rate. When the second through holes 25 and the first through holes 23 are completely misaligned, the adjusting plate 24 can block and seal the first through holes 23.

[0038] The reset mechanism includes a second T-shaped guide rod 701 fixedly connected to the top of each movable plate 301, and a second connecting plate 702 is sleeved on the side wall of the second T-shaped guide rod 701. The second connecting plate 702 is fixed to the side wall of the movable block 27, and a spring 703 is sleeved on the side wall of each second T-shaped guide rod 701.

[0039] The first moving mechanism includes two symmetrically arranged fixed rods 601 inserted into the side wall of the moving block 27, and the two ends of the fixed rods 601 are fixed to the inner side wall of the fixed cover 18. The inner side wall of the fixed cover 18 is rotatably connected to a first threaded rod 603, and the side wall of the first threaded rod 603 is threadedly connected to a first slider 602. The first slider 602 is fixed to the top of the moving block 27. The side wall of the fixed cover 18 is fixedly connected to a first motor 604, and the output end of the first motor 604 is fixed to one end of the first threaded rod 603.

[0040] The second moving mechanism includes an L-shaped block 502 fixedly connected to the side wall of one of the coating covers 19, and a second threaded rod 503 rotatably connected to the side wall of the L-shaped block 502. A second slider 501 is threadedly connected to the side wall of the second threaded rod 503, and the second slider 501 is fixed to the side wall of the adjusting plate 24. A second motor 504 is fixedly connected to the side wall of the L-shaped block 502, and the output end of the second motor 504 is fixed to one end of the second threaded rod 503. When the second motor 504 is started, the rotation of the second motor 504 drives the rotation of the second threaded rod 503, thereby enabling the adjusting plate 24 to move through the second slider 501.

[0041] The conveying mechanism includes two second fixed plates 13 fixedly connected to the top of the base plate 12, and the side wall of each second fixed plate 13 is rotatably connected to a second conveying roller 14 via a second rotating shaft to convey the conveyor belt body 1.

[0042] Working principle: During use, when the conveyor belt body 1 is conveying, it can slide on the surface of the first conveyor roller 16. Under the gravity of the counterweight plate 209, it can squeeze the hydraulic oil, thereby pushing the two first guide rods 206 to move away from each other. At the same time, the first connecting plate 202 and the U-shaped plate 15 drive the two first conveyor rollers 16 to move away from each other, thereby applying a compressive force to the conveyor belt body 1, causing the conveyor belt body 1 to bend and expose cracks. Meanwhile, the first motor 604 is started. The rotation of the first motor 604 drives the rotation of the first threaded rod 603, which drives the moving block 27 to reciprocate along the fixed rod 601. When the moving block 27 moves, it drives the vision sensor 28 to move, thereby improving the accuracy of detection. When a crack is found, the cracked part is maintained and replaced, which can improve its tensile strength.

[0043] During the inspection, when the moving block 27 moves, the moving plate 301 and the brush 302 can be moved by the reset mechanism. At this time, the brush 302 can clean the impurities on the surface of the conveyor belt body 1 and in the cracks. At the same time, the exhaust pipe 306 is connected to the external exhaust equipment for exhaust operation. At this time, the impurities on the surface of the conveyor belt body 1 and in the cracks can be absorbed through the exhaust hole 303 and filtered and collected by the external filter device, thereby ensuring the accuracy of the detection results of the vision sensor 28.

[0044] After the conveyor belt body 1 is cleaned and inspected, when it is conveyed between the two sponge blocks 21, the counterweight plate 209 squeezes the hydraulic oil, which pushes the two second guide rods 403 closer together. This pushes the sliding plate 29 towards the adjusting plate 24, squeezing the coating in the coating cover 19. Simultaneously, the coating enters the sponge block 21 through the second through hole 25 and the first through hole 23, and is coated on the surface of the conveyor belt body 1, improving its wear resistance, anti-slip properties, and anti-aging performance, thereby indirectly improving... To improve the tensile strength of the conveyor belt body 1, when the flow rate needs to be adjusted, the second motor 504 is started. The rotation of the second motor 504 drives the rotation of the second threaded rod 503, which in turn drives the adjusting plate 24 to move through the second slider 501. When the adjusting plate 24 moves, it can adjust the overlapping area between the second through hole 25 and the first through hole 23, thereby adjusting the flow rate. When the second through hole 25 and the first through hole 23 are completely misaligned, the adjusting plate 24 can seal the first through hole 23.
