Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to a tensioning roller for a belt conveyor used in logistics and transportation. Background Technology

[0002] Logistics and transportation are logistics activities that rely on specialized equipment and tools to move goods between different geographical spaces. Their core function is to create spatial benefits for goods and meet social needs.

[0003] With the rapid development of e-commerce, customers can receive their desired items without leaving home. This is inseparable from logistics and transportation, which in turn relies on belt conveyors. Belt conveyors are often equipped with tension rollers that apply constant tension to ensure sufficient friction between the conveyor belt and the drive roller, preventing power transmission failure due to insufficient tension. However, when using the existing tension rollers of belt conveyors, they are often fixed in one place, making it impossible or inconvenient to adjust the tension. This prevents the conveyor belt from becoming loose and affecting transmission efficiency. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A tensioning roller for a belt conveyor used in logistics transportation includes:

[0027] The machine body includes a belt conveyor 1, and a conveyor belt 11 is provided on the surface of the belt conveyor 1. Both the belt conveyor 1 and the conveyor belt 11 are existing products and are not considered as technical protection points of this application. They will not be described in detail here.

[0028] The tensioning mechanism includes a connecting disc 2, which is fixedly connected inside the belt conveyor 1 and is used to connect a tensioning block 28. A limit groove 21 is formed on the surface of the connecting disc 2 to limit the movement of the tensioning block 28. An adjusting threaded rod 22 is rotatably connected to the surface of the connecting disc 2, which drives the connecting block 24 to move by its own rotation. An adjusting knob 23 is fixedly connected to the surface of the adjusting threaded rod 22 to drive the adjusting threaded rod 22 to rotate. The surface of the adjusting threaded rod 22 is threadedly fitted with the connecting block 24, which moves the belt conveyor 1 by its own rotation. The movable tension block 28 moves, and a first connecting shaft 25 is fixedly connected to the surface of the connecting block 24 for connecting the connecting hinge rod 26. A connecting hinge rod 26 is hinged to the surface of the first connecting shaft 25 for connecting the connecting block 24 and the tension block 28. A second connecting shaft 27 is hinged to the end of the connecting hinge rod 26 away from the first connecting shaft 25 for connecting the connecting hinge rod 26. A tension block 28 is fixedly connected to the surface of the second connecting shaft 27 for tensioning the conveyor belt 11. A limit block 29 is fixedly connected to the surface of the tension block 28 for moving at the limit groove 21.

[0029] Furthermore, the adjusting knob 23 is rotatably connected to the surface of the belt conveyor 1, the adjusting threaded rod 22 is rotatably connected to the surface of the connecting plate 2 through the adjusting knob 23, and the connecting block 24 is movably connected to the surface of the connecting plate 2 through the adjusting threaded rod 22. Rotating the adjusting knob 23 can drive the adjusting threaded rod 22 to rotate, thereby driving the connecting block 24 to move on the surface of the connecting plate 2.

[0030] Furthermore, the connecting hinge 26 is hinged to the surface of the connecting block 24 and the first connecting shaft 25, and the connecting hinge 26 is hinged to the surface of the connecting block 24 and the second connecting shaft 27. The movement of the connecting block 24 drives the connecting hinge 26 to rotate, thereby causing the tensioning block 28 to move outward.

[0031] Furthermore, the tensioning blocks 28 are evenly distributed in six groups on the surface of the connecting block 24, and the second connecting shafts 27 are symmetrically distributed in four groups on the surface of the tensioning blocks 28. The tensioning blocks 28 are movably connected to the surface of the connecting disc 2 via the connecting hinge rod 26. The six groups of tensioning blocks 28 move outward to tighten the transmission belt 11 and prevent the transmission belt 11 from loosening.

[0032] Furthermore, the limiting grooves 21 are evenly distributed in six groups on the surface of the connecting plate 2. The limiting block 29 moves through the tensioning block 28 and the surface of the limiting groove 21. The tensioning block 28 is connected to the surface of the conveyor belt 11 through the connecting block 24. The movement of the tensioning block 28 drives the limiting block 29 to move at the limiting groove 21, thereby limiting the movement position of the tensioning block 28 and preventing the tensioning block 28 from deviating.

[0033] Furthermore, the cleaning mechanism includes a fixing rod 3, which is fixedly connected to the surface of the tension block 28 for fixing the connecting plate 31 to the surface of the tension block 28 that contacts the conveyor belt 11. The end of the fixing rod 3 away from the tension block 28 is fixedly connected to the connecting plate 31 for connecting the cleaning wipe 32. The surface of the connecting plate 31 is fixedly connected to the cleaning wipe 32 for cleaning the side of the conveyor belt 11 connected to the tension block 28.

[0034] Furthermore, the fixing rods 3 are symmetrically distributed in two sets on the surface of the connecting plate 31. The connecting plate 31 is fixedly connected to the surface of the tensioning block 28 through the fixing rods 3. The two sets of connecting plates 31 are distributed on both sides of the tensioning block 28, so that the cleaning wipe 32 can move synchronously with the tensioning block 28, thus always acting on the surface of the conveyor belt 11.

[0035] Furthermore, the connecting plate 31 is movably connected to the surface of the belt conveyor 1 via the tensioning block 28, and the cleaning wipe 32 is abutted to the surface of the conveyor belt 11 via the connecting plate 31. The movement of the tensioning block 28 drives the fixed rod 3 and the connecting plate 31 to move synchronously, thereby causing the cleaning wipe 32 to abut against the surface of the conveyor belt 11. When the conveyor belt 11 is running, the cleaning wipe 32 can clean the surface of the conveyor belt 11, preventing dirt from affecting the tightness of the connection between the conveyor belt 11 and the tensioning block 28.

[0036] Working principle: When using the belt conveyor 1, rotating the adjustment knob 23 can drive the adjustment threaded rod 22 to rotate, thereby causing the connecting block 24 to move on the surface of the connecting plate 2. The movement of the connecting block 24 causes the connecting hinge rod 26 to rotate, thereby causing the tensioning block 28 to move outward. The movement of the six sets of tensioning blocks 28 outwards tightens the conveyor belt 11, preventing the conveyor belt 11 from becoming loose. The movement of the tensioning block 28 causes the limiting block 29 to move at the limiting groove 21, thereby limiting the movement position of the tensioning block 28 and preventing the tensioning block 28 from deviating. The movement of the tensioning block 28 causes the fixing rod 3 and the connecting plate 31 to move synchronously, thereby causing the cleaning wipe 32 to press against the surface of the conveyor belt 11. When the conveyor belt 11 is running, the cleaning wipe 32 can clean the surface of the conveyor belt 11, preventing dirt from affecting the tight connection between the conveyor belt 11 and the tensioning block 28.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
