[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0030] To improve the operating reliability of the swing-wheel sorting device, extend its service life, and reduce the installation and maintenance costs thereof, the embodiments of the present disclosure provide a sorting module for a swing-wheel sorting device and a swing-wheel sorting device.

[0031] As Figure 5 shown, the swing-wheel sorting device 100 includes a frame 101 and a plurality of sorting modules 1 arranged in a planar array, and each sorting module 1 is hinged to the frame 101. By driving each sorting module 1 to swing around its hinge center line with the frame 101 and driving the conveyor roller group 14 to rotate, the materials being conveyed can be diverted.

[0032] As Figure 1 and Figure 2As shown, some embodiments of the present disclosure provide a sorting module 1 for a balance wheel sorting device, including:

[0033] A swinging base 11;

[0034] A mounting plate 12, fixedly connected to the swinging base 11 and forming a receiving space 30;

[0035] An outer rotor motor 13, fixed to the mounting plate 12 and located within the receiving space 30;

[0036] A conveying roller group 14, including at least two conveying rollers 140 pivotally mounted on the mounting plate 12 and arranged in parallel. The load-bearing side 14a of the conveying roller group 14 is located above the receiving space 30, and the bottom side 14b of the conveying roller group 14 is located within the receiving space 30;

[0037] At least two supporting rollers 15, pivotally mounted on the mounting plate 12 and located within the receiving space 30. The top-side generatrix 15s of each supporting roller 15 is located above the bottom side 14b of the conveying roller group 14;

[0038] A flat belt 16, wound around the periphery of the outer rotor motor 13, the periphery of each supporting roller 15, and the bottom side 14b of the conveying roller group 14, and in surface contact with the periphery of each conveying roller 140.

[0039] In the embodiments of the present disclosure, descriptions of orientations such as "above", "top", and "bottom" are relative to the normal use state of the sorting module 1. The "fixed connection" between two components can be either a direct connection or an indirect connection through other intermediate components.

[0040] In the embodiments of the present disclosure, the conveying roller 140 is a non-powered roller driven to rotate by the flat belt 16. The multiple conveying rollers 140 can be arranged in parallel in a horizontal plane or in a plane at a certain angle to the horizontal plane. The top-side generatrix 15s of each supporting roller 15 is located above the bottom side 14b of the conveying roller group 14, so that the flat belt 16 exerts a supporting force on the conveying roller group 14. When the flat belt 16 is driven to travel by the outer rotor motor 13, the friction between the flat belt 16 and the conveying roller group 14 drives each conveying roller 140 to rotate, thereby conveying the material (not shown in the figure) on the load-bearing side 14a of the conveying roller group 14. In the embodiments of the present disclosure, the flat belt 16 is not only in surface contact with the periphery of each component it winds around, but also in surface contact with the periphery of each conveying roller 140, that is, a certain wrap angle is formed (the wrap angle refers to the central angle corresponding to the contact arc between the belt and the pulley). In this way, the flat belt can be prevented from slipping during travel, thus ensuring the effectiveness of the transmission.

[0041] In a related technology, the conveying roller group of the sorting module uses a multi-wedge belt drive. Due to its own structural characteristics, the multi-wedge belt is prone to skin shedding and wear, so its service life is short and it needs to be replaced frequently. In addition, the conveying rollers of the conveying roller group need to be designed in structure to match the structure of the multi-wedge belt, resulting in complex processing and high processing costs.

[0042] In another related technology, each conveying roller of the conveying roller group is directly driven by an outer-rotor motor. The outer-rotor motor is floatingly arranged relative to the conveying roller group, and the circumferential side of the outer-rotor motor is in direct contact with the circumferential side of the conveying roller. In this related technology, since the outer-rotor motor is not effectively fixed, the outer-rotor motor is extremely easy to be damaged, and further the maintenance cost of the swing wheel sorting device is high. In addition, the number of outer-rotor motors also results in high production and use costs of the swing wheel sorting device.

[0043] In the embodiments of the present disclosure, as Figure 2 shown, the conveying roller group 14 is driven by a fixedly arranged outer-rotor motor 13. The main components such as the outer-rotor motor 13, the idler roller 15 and the conveying roller group 14 are driven by a flat belt 16. Not only is the structural design simple and the installation and maintenance are convenient, but also the service lives of the flat belt 16 and the outer-rotor motor 13 are relatively long. Therefore, the technical solution of the embodiments of the present disclosure, on the one hand, can improve the operation reliability of the swing wheel sorting device and extend its service life, and on the other hand, can also reduce the control requirements for the manufacturing accuracy and installation accuracy of the sorting module, thereby reducing the installation and maintenance costs.

[0044] As Figure 2 and Figure 3 shown, in some embodiments of the present disclosure, at least one of the at least two idler rollers 15 includes: a shaft 150, a plurality of bearings 151 sleeved on the shaft 150 and a plurality of spacer sleeves 152, wherein each spacer sleeve 152 is located between two adjacent bearings 151. In this way, the manufacturing deviations and installation deviations between different bearings 151 can compensate for each other, so as to reduce or even avoid the deviation of the flat belt 16 during the transmission process to a certain extent, where the deviation means that the flat belt 16 generates a displacement exceeding the threshold range in the width direction. In one embodiment, each of the at least two idler rollers 15 adopts the Figure 3 structure shown in the embodiment, and the deviation correction effect on the flat belt 16 is better.

[0045] As Figure 2 and Figure 4As shown, in some embodiments of the present disclosure, the sorting module 1 further includes: at least one fixed roller 17 pivotally mounted on the mounting plate 12 and located within the accommodation space 30; the flat belt 16 is also wound around the circumferential side of each fixed roller 17. The aforementioned fixed roller 17 includes: a cylindrical portion 170, a first tapered portion 171 connected to one end of the cylindrical portion 170, and a second tapered portion 172 connected to the other end of the cylindrical portion 170. The apexes of the first tapered portion 171 and the second tapered portion 172 are arranged away from each other, that is, away from each other.

[0046] The fixed roller 17 is used to generate a tension force on the flat belt 16, increasing the friction between the flat belt 16 and the conveyor roller group 14, thereby improving the transmission effect of the flat belt 16. Based on the transmission characteristics of the belt that "it runs tight rather than loose, and runs high rather than low", the settings of the first tapered portion 171 and the second tapered portion 172 have an automatic deviation correction effect on the flat belt 16 wound around the cylindrical portion 170, thereby effectively reducing or even avoiding the deviation of the flat belt 16 during transmission. In one embodiment, the taper angles of the first tapered portion 171 and the second tapered portion 172 range from 1° to 3°. In one embodiment, each of the aforementioned at least one fixed roller 17 adopts the Figure 4 structure shown in the embodiment, and the deviation correction effect on the flat belt 16 is better.

[0047] As Figure 2 shown, in some embodiments of the present disclosure, the sorting module 1 further includes: at least one tension roller 18 pivotally mounted on the mounting plate 12 and located within the accommodation space 30; the flat belt 16 is also wound around the circumferential side of each tension roller 18. In one embodiment, the axes of the outer rotor motor 13, at least two support rollers 15, at least two conveyor rollers 140, and at least one fixed roller 17 of the sorting module 1 are parallel, and the axis of at least one of the aforementioned at least one tension roller 18 has an adjustable inclination angle relative to the axis of the outer rotor motor 13.

[0048] One or more tension rollers 18 are used to finely adjust the tension effect of the flat belt 16, thereby increasing the friction between the flat belt 16 and the conveyor roller group 14, achieving the purpose of improving the transmission effect of the flat belt 16. The axis of the tension roller 18 has an adjustable inclination angle relative to the axis of the outer rotor motor 13. By adjusting the magnitude of this inclination angle, for example, by adjusting the installation error of the tension roller 18 to adjust the magnitude of this inclination angle, the deviation of the flat belt 16 can be corrected, thereby further improving the stability of the transmission of the flat belt 16.

[0049] In the embodiments of the present disclosure, the number of conveyor rollers 140, the number of support rollers 15, the number of fixed rollers 17, and the number of tension rollers 18 are not limited, the specific positions of these components are not limited, and furthermore, the relative winding positions of the flat belt 16 on these components are not limited. As Figure 2As shown, the conveying roller group 14 of the sorting module 1 in this embodiment includes four conveying rollers 140, two supporting rollers 15, a fixed roller 17, and a tensioning roller 18. The flat belt 16 is wound in a closed shape around the periphery of the outer rotor motor 13, the periphery of the fixed roller 17, the periphery of one of the supporting rollers 15, the bottom side 14b of the conveying roller group 14, the periphery of the other supporting roller 15, and the periphery of the tensioning roller 18 in sequence.

[0050] In some embodiments of the present disclosure, as Figure 2 shown, the orthographic projection of the axis of the outer rotor motor 13 on the swing base 11 is located between the orthographic projections of the axes of two adjacent ones of the at least two conveying rollers 140 on the swing base 11, and the top side bus 13s of the outer rotor motor 13 is located above the bottom side 14b of the conveying roller group 14; the orthographic projections of the axes of the at least two conveying rollers 140 on the swing base 11 are all located between the orthographic projections of the axes of two of the at least two supporting rollers 15 on the swing base 11.

[0051] In this embodiment, the top side buses 15s of the two supporting rollers 15 are located above the bottom side 14b of the conveying roller group 14, so that the flat belt 16 exerts a supporting force on the conveying roller group 14. The top side bus 13s of the outer rotor motor 13 is located above the bottom side 14b of the conveying roller group 14, so that the outer rotor motor 13 indirectly exerts a supporting force on the two adjacent conveying rollers 140. In the solution of this embodiment, by using the structural characteristics of the outer rotor motor 13, a supporting force is indirectly exerted on two adjacent ones of the conveying rollers 140, so that the flat belt 16 is in surface contact with the two adjacent conveying rollers 140. In this way, the number of the supporting rollers 15 can be reduced, thereby simplifying the structure of the sorting module 1 and reducing the production and installation costs.

[0052] As Figure 1 and Figure 2 shown, in some embodiments of the present disclosure, the swing base 11 includes a swing flange 110 and a transition plate 111 fixedly connected to the swing flange 110, and the mounting plate 12 is fixedly connected to the transition plate 111. The sorting module 1 further includes: a top cover 19 fixedly connected to the mounting plate 12, the top cover 19 has an opening 190, the opening 190 exposes the bearing side 14a of the conveying roller group 14, and is located below the bearing side 14a.

[0053] In some embodiments of the present disclosure, the outer rotor motor 13 is fixed on a motor fixing plate 20, and then fixed on the mounting plate 12 through the motor fixing plate. Between the transition plate 111 and the swing flange 110, between the mounting plate 12 and the transition plate 111, between the motor fixing plate 20 and the mounting plate 12, and between the top cover 19 and the mounting plate 12, fixed connections can be respectively achieved through fasteners such as screws or bolts. The mounting plate 12 and the top cover 19 can protect the outer rotor motor 13, the fixed roller 17, the supporting roller 15, the tension roller 18, the flat belt 16, and the conveying roller group 14 located in the accommodation space 30, which can improve the reliability and safety when the sorting module 1 works.

[0054] As Figure 5 shown, the swing wheel sorting device 100 provided by some embodiments of the present disclosure includes the sorting module 1 of any one of the foregoing embodiments arranged in an array.

[0055] In summary, by adopting the sorting module 1 or the swing wheel sorting device 100 of the above embodiments of the present disclosure, on the one hand, the operation reliability of the swing wheel sorting device 100 can be improved and its service life can be extended; on the other hand, the control requirements for the manufacturing accuracy and installation accuracy of the sorting module 1 can be reduced, thereby reducing the installation and maintenance costs.
