[0049] An electric roller is a component applied to an industrial automation conveying system, which can provide continuous or intermittent power transmission. Due to its characteristics of compact structure, simple installation, stable operation, energy saving and environmental protection, electric rollers have been widely used in modern logistics, manufacturing and other fields, such as being applied in roller conveyor lines.
[0050] In the related art, an electric roller includes a roller motor, a reducer and a cylinder body. The roller motor is connected to the input shaft of the reducer. The roller motor and the reducer are inserted into the cylinder body, and the output shaft of the reducer is fixedly connected to the mounting frame of the electric roller on the other side. After the roller motor is started, the housing of the roller motor and the housing of the reducer drive the cylinder body to rotate.
[0051] However, when the weight of the goods conveyed by the electric roller is relatively large, relative movement is likely to occur between the roller motor 200, the reducer and its cylinder body 100, resulting in the inability to convey the goods normally.
[0052] To solve the above problems, the embodiments of the present application provide an electric roller and a conveying system. The solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings of the specification.
[0053] Figure 1 is a schematic structural diagram of a fixed-connected electric roller provided by an embodiment of the present application; Figure 2 is a partial cross-sectional view of a fixed-connected electric roller provided by an embodiment of the present application; Figure 3 is Figure 2 the enlarged cross-sectional view in
[0054] In a first aspect, as shown in Figures 1 to 3 the embodiments of the present application provide a fixed-connected electric roller, including a cylinder body 100, a roller motor 200, a reducer 300, a fixed connecting piece 400 and a mounting seat 500.
[0055] Among them, the cylinder body 100 is a steel cylinder with a through middle. The roller motor 200, the reducer 300, and the fixed connecting piece 400 are all arranged inside the cylinder body 100. The output end of the roller motor 200 is connected to the input end of the reducer 300, and the reducer 300 converts the high rotational speed output by the roller motor 200 into a low rotational speed. The fixed connecting piece 400 is fixedly connected to the output end of the reducer 300, and the fixed connecting piece 400 is fixedly connected to the cylinder body 100. That is to say, the roller motor 200 and the reducer 300 are fixedly connected to the cylinder body 100 through the fixed connecting piece 400, so that the roller motor 200 can drive the cylinder body 100 to rotate. Since the fixed connecting piece 400 is fixedly connected to the cylinder body 100, it can ensure that there is no relative movement between the roller motor 200, the reducer 300, and the cylinder body 100, and the goods can be stably conveyed.
[0056] Exemplarily, the fixed connecting piece 400 and the cylinder body 100 can be connected by welding, or they can also be fixedly connected by using fasteners.
[0057] In addition, the mounting seat 500 is arranged inside the cylinder body 100, and is fixedly connected to the end of the roller motor 200 facing away from the fixed connecting piece 400.
[0058] The fixed-connected electric roller also includes a core shaft 600, which is arranged on the side of the roller motor of the cylinder body 100. One end of it is fixedly connected to the mounting seat 500, and the other end of the core shaft 600 extends from the inside of the cylinder body 100 to the outside of the cylinder body 100 and is connected to the roller mounting frame. The core shaft 600 and the mounting seat 500 are used to fix the roller motor 200 on the roller mounting frame so that it can drive the cylinder body 100 to rotate.
[0059] That is to say, one end of the roller motor 200 can be fixed on the roller mounting frame through the mounting seat 500 and the core shaft 600. The output end of the roller motor 200 is connected to the cylinder body 100 through the reducer 300 and the fixed connecting piece 400. When the output end of the roller motor 200 rotates, it drives the cylinder body 100 to rotate.
[0060] Exemplarily, the fixed connecting piece 400 can be a connecting disc, which is plugged into the cylinder body 100 and can be welded to the cylinder body 100 to ensure a firm connection.
[0061] In addition, the connecting disc can be fixed inside the cylinder body by fasteners, or by bonding, or by snap connection. It can be known that in the related art, there are other ways to fix the fasteners inside the cylinder body, which will not be listed one by one here.
[0062] Such as Figure 2As shown, in some other examples, the mounting base 500 is a cylinder with a hollow placement cavity 510, which is arranged in the cylinder body 100. A control component for driving the roller motor 200 to act, such as a control board, a motor encoder or a Hall board, is arranged in the placement cavity 510. The control component can be electrically connected to the roller motor 200 through a wire. Since the control component is installed in the placement cavity 510 of the mounting base 500 and does not need to be set separately, the overall installation space of the fixed electric roller can be reduced, and at the same time, the influence of the complex wiring around the fixed electric roller on the operation of the fixed electric roller can be avoided.
[0063] Continuing to refer to Figure 2 and Figure 3 As shown, exemplarily, the mandrel 600 is provided with a through hole 610, and the through hole 610 communicates with the placement cavity 510. The power line and the control line can extend into the interior of the cylinder body 100 through the through hole 610 and be electrically connected to the control component and the roller motor 200 located inside the cylinder body 100.
[0064] In addition, in order to ensure the circumferential relative movement between the cylinder body 100 and the mounting base 500, the roller motor 200 and the reducer 300, the maximum radial dimensions of the mounting base 500, the roller motor 200 and the reducer 300 are all smaller than the diameter of the cylinder body 100, and there is a certain gap between the mounting base 500, the roller motor 200 and the reducer 300 and the inner wall of the cylinder body 100.
[0065] As Figure 2 and Figure 3 As shown, in some embodiments of the present application, the roller motor 200 includes a housing 210, a permanent magnet (not shown in the figure) and a rotor 220. One end of the housing 210 is fixedly connected to the mounting base 500, and the other end is connected to the reducer 300; the permanent magnet is arranged inside the housing 210, the rotor 220 is arranged inside the housing 210, and the rotor 220 is connected to the input end of the reducer 300.
[0066] Exemplarily, the reducer 300 can be configured as a planetary reducer. Specifically, the reducer 300 includes a sun gear 310, planetary gears 320, a planetary carrier 330 and a reducer housing 340; the housing 210 of the roller motor 200 is fixedly connected to the reducer housing 340, the planetary carrier 330 is connected to the reducer housing 340 in a mating manner, the sun gear 310 is connected to the planetary gears 320 in a mating manner, and the planetary gears 320 are arranged on the planetary carrier 330; the rotor 220 is connected to the sun gear 310, and the planetary carrier 330 is connected to the fixed connecting member 400.
[0067] Continuing to refer to Figure 2 and Figure 3As shown, by way of example, the fixed-connected electric roller also includes a non-driven end head assembly, which includes an end cover 700 and an end cover bearing 800. The end cover 700 is fixedly connected to the end of the cylinder body 100, and the core shaft 600 is rotatably connected to the end cover 700 through the end cover bearing 800. Specifically, the end cover bearing 800 is arranged in the end cover 700, and the core shaft 600 is fitted in the end cover bearing 800. For example, the end cover 700 can be clamped, bolted or welded to the end of the cylinder body 100. There is at least one end cover bearing 800, which is fitted and installed in the end cover 700, and the core shaft 600 is then fitted and installed in the end cover bearing 800.
[0068] Correspondingly, the fixed-connected electric roller also includes a driving end head assembly 900, which is arranged on the side opposite to the roller motor 200. The driving end head assembly 900 includes a sprocket end head 910, a rotating shaft 920 and an end head bearing 930. Among them, the sprocket end head 910 is installed at one end of the cylinder body 100 away from the roller motor 200. There are at least two end head bearings 930 arranged in the sprocket end head 910, and the rotating shaft 920 is fitted and installed in at least two end head bearings 930. Specifically, the two end head bearings 930 are respectively located at both ends of the rotating shaft 920.
[0069] In some examples, the sprocket end head 910 is configured with a sprocket 911. When arranging a conveyor line using the fixed-connected electric roller, the fixed-connected electric roller can be used as a power roller, and the sprockets 911 of adjacent fixed-connected electric rollers are connected to each other by a chain.
[0070] Figure 4 It is a schematic structural diagram of a fixed-connected electric roller provided by another embodiment of the present application.
[0071] Refer to Figure 4 As shown, in some examples, the fixed-connected electric roller includes at least one sprocket 911, and at least one sprocket 911 is fixedly connected to the cylinder body 100. For example, one sprocket 911 is fixedly arranged at one end of the fixed-connected electric roller, or two sprockets 911 can be fixedly and juxtaposed at one end of the fixed-connected electric roller.
[0072] In some other examples, at least one sprocket 911 is arranged at both ends of the fixed-connected electric roller, and at least one sprocket 911 is fixedly connected to the cylinder body 100. For example, one sprocket 911 is arranged at both ends of the fixed-connected electric roller, or two sprockets 911 are juxtaposed. By way of example, at one end of the cylinder body 100 where the driving end head assembly 900 is provided, one or two sprockets 911 are arranged on the sprocket end head 910, and at one end of the cylinder body 100 away from the driving end head 900, one or two sprockets 911 are fixedly arranged on the cylinder body 100.
[0073] When the fixed electric roller is used as a driving roller, the sprockets 911 at both ends thereof are respectively connected to the sprockets at both ends of the non-powered roller, so that the forces at both ends of the non-powered roller are evenly distributed, and thus the rotation is more stable.
[0074] In a second aspect, an embodiment of the present application provides a conveying system, including the fixed electric roller as described in the first aspect. Since the conveying system includes the fixed electric roller in any of the above technical solutions, it has all the beneficial effects of the fixed electric roller in any of the above technical solutions, which will not be elaborated herein.

[0076] The above specific implementation manners further elaborate on the purpose, technical solutions, and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific implementation manners of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
