Abstract
Description

[0002] Belt conveyors are highly efficient, continuous transport machines. As an integral part of modern production and logistics systems, they are widely used across various industries. Their operating principle is that a belt, powered by a transmission mechanism, moves around rollers, forming a closed-loop transmission system. The material being conveyed is placed on the belt and transported to the desired location as it moves.
[0003] Belt transmission equipment is mainly composed of core components such as the frame, conveyor belt, belt roller, tensioning device and transmission device. The wider the conveyor item, the wider the conveyor belt, which will cause the belt roller to be too long. Currently, there are two commonly used belt rollers: a fully solid roller and a hollow roller with a core shaft. However, when the belt roller is long, the mass of the fully solid roller is large, which will lead to excessive moment of inertia, thereby increasing the servo motor load and belt tension, and increasing power consumption. Although the weight of the hollow roller with a core shaft is reduced compared to the fully solid roller, when the hollow roller is long, the center suspended part of the hollow roller is too large, resulting in increased deflection and the risk of broken shaft when carrying materials.

[0035] Belt conveyors are highly efficient, continuous transport machines. As an integral part of modern production and logistics systems, they are widely used across various industries. Their operating principle is that a belt, powered by a transmission mechanism, moves around rollers, forming a closed-loop transmission system. The material being conveyed is placed on the belt and transported to the desired location as it moves.
[0036] Belt transmission equipment is mainly composed of core components such as the frame, conveyor belt, belt roller, tensioning device and transmission device. The wider the conveyor item, the wider the conveyor belt, which will cause the belt roller to be too long. Currently, there are two commonly used belt rollers: a fully solid roller and a hollow roller with a core shaft. However, when the belt roller is long, the mass of the fully solid roller is large, which will lead to excessive moment of inertia, thereby increasing the servo motor load and belt tension, and increasing power consumption. Although the weight of the hollow roller with a core shaft is reduced compared to the fully solid roller, when the hollow roller is long, the center suspended part of the hollow roller is too large, resulting in increased deflection and the risk of broken shaft when carrying materials.
[0037] Therefore, in order to reduce weight, lower energy consumption, improve structural strength, and avoid the risk of shaft breakage, this embodiment provides a conveying roller set.
[0038] like Figures 1 to 5 As shown, the conveying roller group includes at least two roller assemblies 1 and a support member 2. Each roller assembly 1 includes a core shaft 11 and multiple outer rollers 12. The multiple outer rollers 12 are equidistantly arranged on the core shaft 11 along the first direction and are rotatably connected to the core shaft 11. A support member 2 is provided between each two adjacent outer rollers 12, and the two ends of the support member 2 are respectively connected to two adjacent core shafts 11.
[0039] The conveying roller group is provided with at least two roller assemblies 1, and multiple outer rollers 12 are sleeved on the core shaft 11 of each roller assembly 1. On the one hand, compared with a solid roller, the weight is reduced, the moment of inertia is reduced, and the energy consumption is reduced. On the other hand, by sleeved with multiple outer rollers 12 on the core shaft 11, the risk of a single outer roller 12 breaking due to a too long central suspended part and too large deflection is avoided. In addition, a support member 2 is provided between each two adjacent outer rollers 12, with both ends respectively connected to the two adjacent core shafts 11, so that the support member 2 is used to strengthen the structural strength of the core shaft 11, thereby avoiding the risk of the core shaft 11 breaking due to too long length and too large deflection.
[0040] The conveyor roller assembly can be used in various conveying systems. In this embodiment, the conveyor roller assembly is primarily used in a pole piece transmission system. The number of roller assemblies 1 in the conveyor roller assembly and the number of outer rollers 12 sleeved on the core shaft 11 in the roller assembly 1 can be freely set according to needs. In this embodiment, the conveyor roller assembly is provided with two roller assemblies 1, and each roller assembly 1 is provided with two outer rollers 12 sleeved on the outside of the core shaft 11. Therefore, only one support member 2 is required in the conveyor roller assembly of this embodiment. In this embodiment, the support member 2 is made of plate material.
[0041] Alternatively, as Figure 2 As shown, the roller assembly 1 further includes a rotating member 13. The rotating member 13 is disposed on both ends of the outer roller 12 along the first direction and is sleeved on the outside of the core shaft 11. The outer roller 12 is rotatably connected to the rotating member 13. The provision of the rotating member 13 not only achieves the rotational connection between the outer roller 12 and the core shaft 11 and supports the outer roller 12, but also reduces frictional resistance and improves the flexibility of the outer roller 12 in rotating outside the core shaft 11.
[0042] Furthermore, if Figure 2 As shown, both ends of the outer roller 12 along the first direction are provided with multiple rotating members 13 that are sleeved on the outside of the core shaft 11. Providing multiple rotating members 13 at both ends of the outer roller 12 along the first direction, on the one hand, helps further improve the support for the outer roller 12 and increase the overall structural strength; on the other hand, it further reduces frictional resistance and improves the flexibility of the outer roller 12 in rotating outside the core shaft 11. The number of rotating members 13 on one side of the outer roller 12 can be freely adjusted according to actual needs. In this embodiment, each outer roller 12 is provided with two juxtaposed transmission members on one side.
[0043] Alternatively, as Figure 1 、 Figure 2 As shown, the roller assembly 1 also includes a first positioning sleeve 14, which is sleeved onto the core shaft 11 and positioned between two adjacent outer rollers 12. The two ends of the first positioning sleeve 14 along the first direction respectively abut against two adjacent rotating members 13 of the two outer rollers 12. The two ends of the support member 2 are respectively connected to the first positioning sleeve 14. By sleeved on the core shaft 11, the two outer rollers 12 can be positioned, thereby fixing the spacing between them. Furthermore, the support member 2 is indirectly connected to the core shaft 11 via the first positioning sleeve 14, forming a separate structure from the core shaft 11, thereby facilitating later disassembly and maintenance of the core shaft 11 and support member 2. In this embodiment, the first positioning sleeve 14 is made of 304 stainless steel.
[0044] Alternatively, as Figure 1 、 Figure 2 As shown, the roller assembly 1 further includes a fixing seat 15, which is provided on both sides of the core shaft 11 along the first direction, and the core shaft 11 is inserted into the fixing seat 15. By providing the fixing seat 15 on both sides of the core shaft 11, it is convenient to fix the core shaft 11.
[0045] Furthermore, if Figure 1 、 Figure 2As shown, the roller assembly 1 further includes a second positioning sleeve 16, which is sleeved on the core shaft 11. The two ends of the second positioning sleeve 16 along the first direction respectively abut against the fixed seat 15 and the rotating member 13 adjacent to the fixed seat 15. By providing the second positioning sleeve 16 on the core shaft 11, the outer roller 12 and the fixed seat 15 can be limited, and the distance between the outer roller 12 and the fixed seat 15 can be fixed.
[0046] Alternatively, as Figure 3 、 Figure 4 As shown, the fixing seat 15 is provided with an insertion groove 151, and both ends of the core shaft 11 are provided with a limiting plane 111. The two ends of the core shaft 11 are inserted into the insertion groove 151, and the limiting plane 111 abuts against the groove wall of the insertion groove 151. By providing the limiting plane 111 at both ends of the core shaft 11, when the core shaft 11 is inserted into the insertion groove 151 of the fixing seat 15, the limiting plane 111 abuts against the wall of the insertion groove 151, thereby limiting the rotation of the core shaft 11 and preventing the core shaft 11 from rotating in the insertion groove 151 of the fixing seat 15 due to external factors such as vibration.
[0047] Alternatively, as Figure 1 、 Figure 5 As shown, arcuate grooves 21 are formed at both ends of the support member 2 where it connects to the core shaft 11. The arcuate grooves 21 allow the support member 2 to fit more closely with the circular cross-section core shaft 11, providing a more secure connection. In this embodiment, the size of the arcuate grooves 21 matches the diameter of the core shaft 11.
[0048] Optionally, the rotating member 13 is a bearing, with its inner ring mounted on the core shaft 11 and the outer roller 12 mounted on its outer ring. Using a bearing as the rotating member 13 facilitates availability and reduces manufacturing costs. In this embodiment, the rotating member 13 utilizes a deep groove ball bearing, which offers high load-bearing capacity and extremely low friction resistance.
[0049] In this embodiment, if Figure 6 As shown, a conveying mechanism is also provided, which includes the above-mentioned conveying roller group. The conveying mechanism also includes a conveyor belt 100, an active roller 200 and a driving member. The conveyor belt 100 is sleeved on the outside of the active roller 200 and the conveying roller group. The active roller 200 is connected to the driving member, and the driving member is used to drive the active roller 200 to rotate.
[0050] The conveying mechanism uses the above-mentioned conveying roller group, which is light in weight, thereby effectively reducing power loss and operating costs. In addition, the structural strength of the conveying roller group is relatively high, thereby reducing the possibility of damage due to broken shafts and extending the service life.
[0051] In this embodiment, the conveying mechanism comprises two sets of conveyor rollers arranged opposite each other, wherein a driving roller 200 is located between the two conveyor rollers, and a conveyor belt 100 is disposed outside the driving roller 200 and the two conveyor rollers. A driving member (not shown) drives the driving roller 200 to rotate, which in turn drives the two conveyor rollers to rotate via the conveyor belt 100, thereby achieving the conveying function. The driving member is a servo motor.
[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
