All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0051] It should be understood that some terms involved in the description of the present application, such as "parallel", "center", "axis line", "axial direction", "both sides", "horizontal", "top", "bottom", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the scope of protection of the present application.

[0052] The following combines the attached Figures 1 - 6 The drive device and conveyor system for the modular belt drum of the present application will be further described in detail below.

[0053] In a first aspect, the present application discloses a drive device for a modular belt drum; as Figure 1 shown, the drive device may include a roller module 11, a top support plate 12, a bottom support plate 13, a driving member 14, and a driving mechanism 15.

[0054] Specifically, as Figure 4As shown, the roller module 11 further includes a disc-shaped base 111, a steering roller 112 disposed on the top of the base 111, and two parallel positioning columns 113 and a pendulum wheel transmission column 114 disposed at the bottom of the base 111. Among them, the positioning column 113 is located at the center of the bottom of the base 111, and its length is greater than that of the pendulum wheel transmission column 114.

[0055] As Figure 1 shown, both the top support plate 12 and the bottom support plate 13 are straight plate members. A bearing hole 121 is formed through the top support plate 12. Among them, a roller module 11 is rotatably disposed in a bearing hole 121 through its base 111.

[0056] The bottom support plate 13 is disposed parallel to the bottom of the top support plate 12, and a positioning hole 131 is formed through it. Among them, the positioning column 113 of a roller module 11 is adaptively disposed in a positioning hole 131 to perform radial limit on it, and in a subsequent another embodiment ( Figure 5 the embodiment shown), when the roller module 11 can move up and down axially, the positioning hole 131 also plays a guiding role. It should be noted that the number and arrangement positions of the bearing holes 121 and the positioning holes 131 on the top support plate 12 and the bottom support plate 13 can be appropriately set according to specific usage requirements (such as the number and positions of the rollers 211 on the modular belt 21), and will not be specifically described here.

[0057] The driving member 14 is configured to reciprocate between the top support plate 12 and the bottom support plate 13 in a predetermined direction (perpendicular to the belt traveling direction, where the belt traveling direction is shown by the arrow 14a in Figure 1 ), so as to drive the pendulum wheel transmission column 114 to rotate around the positioning column 113, thereby driving the roller module 11 to rotate around its axis.

[0058] The driving mechanism 15 is connected to the driving member 14, and is mainly used to provide power for the driving member 14 to drive the driving member 14 to move.

[0059] In summary, for the driving device of the modular belt roller of the present application, the driving member 14 drives the pendulum wheel transmission column 114 to rotate around the positioning column 113, thereby driving the rotation of the roller module 11 to realize the driving of the roller on the modular belt. This driving device has fewer structural components, a more reasonable layout, and stronger overall stability.

[0060] Further, in the driving device of the modular belt roller of the present application, the driving member 14 can be set into various suitable structural shapes according to needs; such as Figure 1As shown, in a preferred embodiment of the present application, the preferred driving member 14 is in a straight plate shape and is disposed parallel between the top support plate 12 and the bottom support plate 13; in addition, driving holes 141 of a predetermined shape are formed in the driving member 14, wherein one driving hole 141 is configured to allow the positioning post 113 and the pendulum wheel transmission post 114 of one roller module 11 to pass through simultaneously, and when following the reciprocating movement of the driving member 14, it can drive the pendulum wheel transmission post 114 to rotate around the positioning post 113.

[0061] Similarly, the shape of the driving hole 141 can be appropriately selected according to needs; as Figure 1 shown, in the above preferred embodiment of the present application, the preferred driving hole 141 is approximately convex-shaped, including a positioning post hole 1411 at the bottom and a pendulum wheel hole 1412 at the top; wherein, the positioning post hole 1411 is in a strip shape and is arranged along the reciprocating movement direction of the driving member 14 (see Figure 1 in the manner perpendicular to the arrow 14a shown), and its length is adapted to the reciprocating movement distance of the driving member 14, that is, the reciprocating movement distance of the driving member 14 can be limited by this length, and the positioning post 113 is disposed through the positioning post hole 1411; it should be noted that due to the limitation of the positioning hole 131 on the bottom support plate 13, when the driving hole 141 moves with the driving member 14, the positioning post 113 will not have a radial offset.

[0062] Furthermore, the shape of the pendulum wheel hole 1412 in the driving hole 141 is adapted to the shape of the pendulum wheel transmission post 114, and the pendulum wheel transmission post 114 is disposed through the pendulum wheel hole 1412; it can be understood that due to the positional and shape relationship between the pendulum wheel transmission post 114, the positioning post 113, and the convex-shaped driving hole 141, when the driving hole 141 reciprocates, it can drive the pendulum wheel transmission post 114 to rotate around the positioning post 113, thereby driving the roller module 11 to rotate around its axis, and its rotation angle can be achieved by changing, for example, the radial distance between the pendulum wheel transmission post 114 and the positioning post 113 (and correspondingly adjusting the shape of the driving hole 141), which will not be elaborated here one by one.

[0063] As the above example of the structure of the driving member 14 illustrates, the driving member 14 can be of various suitable structural shapes. For example, in other embodiments, the driving member 14 can be in a rod shape, and the reciprocating movement of the driving rod can also achieve the driving of the pendulum wheel transmission post 114; other methods will not be specifically elaborated here.

[0064] Furthermore, in the above driving device of the present application, the top support plate 12 and the bottom support plate 13 can be fixedly connected in a variety of suitable ways; as Figure 1As shown, in a preferred embodiment of the present application, it is preferred that the top support plate 12 and the bottom support plate 13 are connected by fixing bolts 16 vertically penetrating therethrough; correspondingly, in order that the fixing bolts 16 do not affect the movement of the driving member 14, a long strip-shaped first guiding hole 142 may be provided on the driving member 14. The first guiding hole 142 is arranged along the reciprocating movement direction of the driving member 14, and its length is adapted to the reciprocating movement distance of the driving member 14, and the fixing bolts 16 are arranged through the first guiding hole 142. It should be noted that the number and arrangement positions of the fixing bolts 16 can be appropriately set according to the shapes and sizes of the top support plate 12 and the bottom support plate 13, as well as the number and positions of the roller modules 11 therebetween. In this embodiment, it is preferred to arrange one at each of the four corners of the straight plate-shaped driving member 14.

[0065] Furthermore, in the above driving device of the present application, in order to further ensure the stability of the driving member 14 during movement, a guiding block 17 may also be fixedly arranged between the top support plate 12 and the bottom support plate 13; correspondingly, a long strip-shaped second guiding hole 143 is also provided on the driving member 14. The second guiding hole 143 is arranged along the reciprocating movement direction of the driving member 14, and its length is adapted to the reciprocating movement distance of the driving member 14, and the guiding block 17 is arranged through the second guiding hole 143. Similarly, the number, shape, arrangement method and arrangement positions of the guiding blocks 17 can be appropriately selected according to needs. In this embodiment, it is preferred that the guiding blocks 17 are cylindrical, and a plurality of guiding blocks 17 are evenly distributed within the covered area of the straight plate-shaped driving member 14. In addition, the axial ends of the guiding blocks 17 can be fixedly connected (such as welded) to the bottom surface of the top support plate 12, or to the top surface of the bottom support plate 13.

[0066] Furthermore, in the driving device for the modular belt drum of the present application, the driving mechanism 15 can be selected as various suitable structures according to needs; such as Figure 1 and Figure 3 As shown, in a preferred embodiment of the present application, it is preferred that the driving mechanism 15 includes a cylinder 151 and a corresponding cylinder driving system (not shown in the figure); the cylinder 151 is arranged at the bottom of the bottom support plate 13, and one end ( Figure 1 the left end in Figure 1 the figure) is connected to the bottom support plate 13, and the other end ( Figure 1 the right end in

[0067] the figure) is connected to the driving member 14 to drive the driving member 14 to make reciprocating movement.

[0068] Specifically, the top end of the first fixing block 152 is fixedly connected to the driving member 14 through, for example, bolts. The bottom end of the first fixing block 152 is provided with double ears. One end of the first connecting member 153 is provided with a single ear, and this single ear is hinged in the double ears of the first fixing block 152 through a pin shaft. The other end of the first connecting member 153 is fixedly connected to the end of the piston rod of the cylinder 151 through, for example, bolts.

[0069] The top end of the second fixing block 154 is fixedly connected to the bottom surface of the bottom support plate 13 through, for example, bolts. The bottom end of the second fixing block 154 is provided with double ears. One end of the second connecting member 155 is provided with a single ear, and this single ear is hinged in the double ears of the second fixing block 154 through a pin shaft. The other end of the second connecting member 155 is fixedly connected to the cylinder block of the cylinder 151 through, for example, bolts.

[0070] Furthermore, in the driving device for the modular belt roller of the present application, the steering roller 112 on the roller module 11 can be arranged in a variety of known suitable structures. In this embodiment, as Figure 4 shown, preferably, a roller mounting cylinder 115 is fixedly arranged on the top of the base 111 of the roller module 11. Among them, the steering roller 112 is rotatably arranged in the roller mounting cylinder 115 through a pin shaft, and the highest point of the roller surface of the steering roller 112 is higher than the top surface of the roller mounting cylinder 115, so as to facilitate contact with the roller on the belt.

[0071] It should be noted that in the above preferred embodiment, the roller module 11 is configured to be fixed in the axial direction, that is, the steering roller 112 in the roller module 11 is always in contact with the roller 211 on the belt. When the axis of the steering roller 112 rotates to be perpendicular to the axis of the roller 211, it plays a braking role, making the roller 211 always stationary. When the axis of the steering roller 112 rotates to form an angle less than 90 degrees with the axis of the roller 211, due to the movement of the belt, the roller 211 on the belt will rub against the steering roller 112, thereby making the roller 211 rotate.

[0072] Furthermore, in another preferred embodiment of the present application, in order to reduce the unnecessary (i.e., when no diversion is required) frictional contact between the steering roller 112 and the roller 211, the roller module 11 can be arranged as a liftable structure.

[0073] Specifically, as Figure 5 、 Figure 6As shown in the figure, the drive device for the modular belt roller of the present application may further include a bottom support 18; the bottom support 18 is cylindrical and fixedly arranged (such as nested) in the bearing hole 121, so that a roller module 11 is rotatably arranged in the inner cavity of a bottom support 18 through its base 111; wherein, the diameter of the roller mounting cylinder 115 is equal to that of the bottom support 18, and they are in contact through the axial end faces, and the contact surfaces between them are all configured as regular and adapted wave teeth; it can be understood that this wave tooth end face structure enables the roller mounting cylinder 115 to rise or fall as the rotation angle changes during the rotation process, so as to simultaneously realize the steering of the steering roller 112 and the contact or separation from the roller 211.

[0074] Further, to enhance the stability of the roller module 11 with lifting function, a limit plate 19 may also be included; the limit plate 19 is vertically and fixedly arranged (for example, by welding) on the top surface of the top support plate 12. Among them, the vertical height of the limit plate 19 is less than the distance between the top surface of the top support plate 12 and the support frame of the modular belt 21; in addition, at least one roller module 11 is arranged between two adjacent limit plates 19, and on the opposite side surfaces of the two limit plates 19, arc-shaped grooves adapted to the shape of the roller mounting cylinder 115 are formed, so as to radially limit the roller module 11 from opposite sides through the arc-shaped grooves of the two limit plates 19.

[0075] It should be noted that the number and arrangement position of the limit plates 19 can be appropriately selected according to needs. For example, when the number of roller modules 11 is multiple and arranged in columns along the length direction of the limit plate 19, two limit plates 19 can be shared on both sides of the roller modules 11 in the same column, and one limit plate 19 can be shared between two adjacent columns of roller modules 11.

[0076] In a second aspect, the present application also discloses a conveyor system; as Figures 1 - 3 shown, the conveyor system may include a modular belt 21 with a roller 211, a belt drive mechanism (not shown in the figure), and a drive device 22; the drive device 22 is arranged at the bottom of the modular belt 21 and is used to controllably drive the roller 211 of the modular belt 21 to rotate. Further, preferably, the drive device 22 may adopt the drive device described in any one of the above first aspects. Among them, at least one roller module 11 is arranged at the bottom of each roller 211 for driving, and the specific number is not exemplified here.

[0077] In addition, as Figure 5 and Figure 6 shown, in another embodiment of the above first aspect, that is, in the embodiment where the roller module 11 adopts the matching structure of the bottom support 18 with a wave tooth shape and the roller mounting cylinder 115:

[0078] When the roller mounting cylinder 115 rotates until its wave teeth are misaligned with the wave teeth of the base 18 , the roller module 11 can rise axially, so that the steering roller 112 contacts the roller 211 of the modular belt 21 .

[0079] When the roller mounting cylinder 115 rotates until its wave teeth are fully meshed with the wave teeth of the base 18, the roller module 11 can be lowered axially, so that the steering roller 112 is separated from the roller 211 of the modular belt 21. Of course, the specific lifting height of the roller module 11 can be adjusted by adjusting the tooth height of the wave teeth.

[0080] It should also be noted that, in this embodiment, it is further preferred that the diameter of the steering roller 112 in the roller module 11 is greater than or equal to the diameter of the roller 211 in the modular belt 21 .

[0081] Similarly, in the conveyor system of the present application, the drive member 14 drives the pendulum transmission column 114 to rotate around the positioning column 113, thereby driving the rotation of the roller module 11 to realize the driving of the roller on the modular belt. The driving device has fewer structural components, a more reasonable layout, and greater overall stability.

[0082] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
