Description

Technical Field

[0001] This utility model relates to the field of conveyor tension adjustment technology, and in particular to a conveyor tension adjustment structure for logistics conveying. Background Technology

[0002] When conveyors used in logistics transportation are in operation, the conveyor belt is prone to loosening due to long-term stress, which affects the conveying efficiency. Most existing tension adjustment structures are manually adjustable, requiring manual adjustment by turning bolts after the machine is stopped. This is not only time-consuming but also interrupts the logistics transportation process and is difficult to adapt to the real-time tension requirements when the conveying volume fluctuates.

[0003] While some automatic tensioning structures do not require manual operation, they are complex in structure and have poor adaptability. They cannot flexibly adapt to conveyor belts of different widths, and are prone to over- or under-tensioning during adjustment, which leads to faster wear of the conveyor belt, shortens its service life, and increases the maintenance cost of logistics transportation.

First ball bearings 13 are correspondingly sleeved and movably connected to the first fixed rods 12. Multiple first rollers 6 are movably connected between the conveyor frames 1. The first rollers 6 are correspondingly sleeved and movably connected to the first ball bearings 13, so that the first rollers 6 can rotate flexibly with the operation of the conveyor belt 5, ensuring smooth conveying of the conveyor belt 5.

[0020] Specifically, the inner side of the inclined frame 2 is fixedly connected with symmetrical fifth fixed rods 19, and a second roller 7 is movably connected to the fifth fixed rod 19. The lower end of the conveyor frame 1 is fixedly connected with symmetrical first adjusting frames 3, and the inner side of the first adjusting frames 3 is fixedly connected with a corresponding third fixed rod 17. A third roller 28 is movably connected to the third fixed rod 17. The lower end of the conveyor frame 1 is fixedly connected with symmetrical second adjusting frames 4, and the inner side of the second adjusting frames 4 is fixedly connected with a corresponding fourth fixed rod 18. A fourth roller 29 is movably connected to the fourth fixed rod 18.

[0021] Specifically, the inner side of the adjusting plate 10 is fixedly connected with symmetrical second fixing rods 15, and a second ball bearing 16 is movably connected to the second fixing rod 15. A tension roller 8 is movably connected to the second ball bearing 16, and the tension of the conveyor belt 5 is adjusted by adjusting its own position.

[0022] Specifically, the first roller 6, the second roller 7, the tension roller 8, and the fourth roller 29 are correspondingly and movably connected to the inner side of the conveyor belt 5, and the third roller 28 is movably connected to the outer side of the conveyor belt 5.

[0023] Specifically, a threaded bushing 21 is fixedly connected through the first bearing plate 9, and a first lubricating oil hole 22 is opened on the threaded bushing 21. A symmetrical connecting bushing 23 is fixedly connected to the first bearing plate 9, and a second lubricating oil hole 24 is opened on the connecting bushing 23 respectively. Lubricating oil is added to ensure smooth sliding between the two.

[0024] Specifically, an adjusting motor 11 is fixedly connected through the side of the second bearing plate 14, and a threaded rod 25 is rotatably connected to the side of the adjusting motor 11. A threaded bushing 21 is movably connected to the threaded rod 25. A symmetrical connecting rod 26 is fixedly connected to the side of the second bearing plate 14, and a corresponding connecting bushing 23 is movably connected to the connecting rod 26, providing guidance for the movement of the second bearing plate 14 and ensuring smooth and non-deviational movement.

[0026] Working principle: The adjusting motor 11 is started, which drives the threaded rod 25 to rotate. Because the threaded bushing 21 is fitted onto the threaded rod 25, and the connecting rod 26 on the side of the second bearing plate 14 slides along the connecting bushing 23, the rotation of the threaded rod 25 is converted into smooth movement of the second bearing plate 14. Simultaneously, lubricating oil can be added through the first lubrication hole 22 and the second lubrication hole 24 to ensure smooth transmission and sliding. The second bearing plate 14 drives the adjusting plate 10 to move synchronously. The tensioning slider 27 on the outer side of the adjusting plate 10 slides along the adjusting guide rail 20 to ensure stable movement of the adjusting plate 10. The adjusting plate 10 then drives the tensioning roller 8 to adjust its position. The tensioning roller 8 is in contact with the inner side of the conveyor belt 5, and its positional change directly alters the tension of the conveyor belt 5. The first roller 6, the second roller 7, and the fourth roller 29 support the conveyor belt 5 from the inside, while the third roller 28 limits its movement from the outside. This, combined with the smooth operation of the tensioned conveyor belt 5, completes the coordination of tension adjustment and material transport.
