Description

[0002] Conveyor belt is a kind of equipment 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 belt is a common type of conveyor belt, usually made of polyester fiber (PET). Polyester fiber has high tensile strength, so polyester conveyor belt usually has good tensile resistance and is suitable for long-distance and high-load conveying tasks. Conveyor belt needs to be used with drive device, conveyor shaft, roller, tensioning device and other components.

[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, 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 an extrusion force to the conveyor belt body 1, so that the conveyor belt body 1 is extruded and bent, so as to expose the cracks. At the same time, the first motor 604 is started, and the rotation of the first motor 604 drives the rotation of the first threaded rod 603, which can drive the moving block 27 to reciprocate along the fixed rod 601. When the moving block 27 moves, it can drive the visual sensor 28 to move, thereby improving the accuracy of detection. When cracks are found, the cracked part is maintained and replaced, which can improve its tensile resistance.

[0043] During detection, when the moving block 27 moves, the moving plate 301 and the bristles 302 can be driven to move through the reset mechanism. At this time, the 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 to perform the 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, and can be filtered and collected through an external filtering device, thereby ensuring the accuracy of the detection results of the visual sensor 28.

[0044] After the conveyor belt body 1 is cleaned and inspected, when it is transported between the two sponge blocks 21, 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 in the direction close to the adjustment plate 24, and can squeeze the paint in the coating cover 19. At the same time, it passes through the second through hole 25 and the first through hole 23 and enters the sponge block 21, and is coated on the surface of the conveyor belt body 1, improving the wear resistance, anti-skid and anti-aging performance, thereby indirectly improving In order to improve the elongation resistance 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, so that the adjustment plate 24 can be driven to move through the second slider 501. When the adjustment plate 24 moves, the overlapping area between the second through hole 25 and the first through hole 23 can be adjusted, so as to adjust the flow rate. When the second through hole 25 is completely staggered with the first through hole 23, the adjustment plate 24 can seal the first through hole 23.
