As shown in fig. 1, the top support plate 12 and the bottom support plate 13 are both straight plate members; the top supporting plate 12 has a bearing hole 121 formed therethrough, wherein a roller module 11 is rotatably disposed in the bearing hole 121 through the base 111 thereof.

The bottom supporting plate 13 is arranged at the bottom of the top supporting plate 12 in parallel, and a positioning hole 131 is formed in the bottom supporting plate in a penetrating mode; the positioning posts 113 of one roller module 11 are adapted to be disposed in one positioning hole 131 to radially limit the position of the roller module, and subsequently in another embodiment (the embodiment shown in fig. 5), when the roller module 11 can be lifted and lowered along the axial direction, the positioning holes 131 also perform a guiding function. It should be noted that the number and the 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 set appropriately according to specific requirements (for example, the number and the positions of the rollers 211 on the modular belt 21), and detailed description thereof is omitted.

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, which is indicated by an arrow 14a in fig. 1) to rotate the balance wheel transmission post 114 around the positioning post 113, thereby driving the roller module 11 to rotate around the axis thereof.

The driving mechanism 15 is connected to the driving member 14 and is mainly used for providing power to the driving member 14 to drive the driving member 14 to move.

In summary, the driving device for the modular belt roller of the present application drives the balance wheel transmission post 114 to rotate around the positioning post 113 through the driving part 14, so as to drive the roller module 11 to rotate, thereby realizing the driving of the modular belt roller.

Further, in the driving device for the modular belt roller of the present application, the driving member 14 may be configured in various suitable structural shapes as required; in a preferred embodiment of the present application, as shown in fig. 1, the driving member 14 is preferably in the form of a straight plate and is disposed in parallel between the top support plate 12 and the bottom support plate 13; in addition, a driving hole 141 with a predetermined shape is formed in the driving member 14, wherein one driving hole 141 is configured to allow the positioning post 113 and the balance wheel transmission post 114 of one roller module 11 to simultaneously pass through, and can drive the balance wheel transmission post 114 to rotate around the positioning post 113 when the driving member 14 reciprocates.

Further, the shape of the balance hole 1412 in the driving hole 141 is matched with the shape of the balance driving post 114, and the balance driving post 114 is arranged in the balance hole 1412 in a penetrating manner; it can be understood that, due to the position and shape relationship between the balance wheel transmission column 114 and the positioning column 113 and the convex-shaped driving hole 141, when the driving hole 141 reciprocates, the balance wheel transmission column 114 can be driven to rotate around the positioning column 113, so as to drive the roller module 11 to rotate around the axis thereof, and the rotation angle thereof can be realized by changing, for example, the radial distance between the balance wheel transmission column 114 and the positioning column 113 (and the shape of the corresponding adjustment driving hole 141), which is not described in detail herein.

It should be noted that the number and the arrangement position of the fixing bolts 16 can be set appropriately according to the shape and size of the top support plate 12 and the bottom support plate 13 and the number and the position of the roller modules 11 therebetween, and in this embodiment, it is preferable to arrange one fixing bolt at each of the four corners of the straight plate-shaped driving member 14.

Further, in the above-mentioned driving device of the present application, in order to further ensure the stability of the driving member 14 during the structural movement, a guide block 17 may be fixedly disposed between the top supporting plate 12 and the bottom supporting plate 13; correspondingly, the driving member 14 is further provided with a second elongated guide hole 143, the second guide hole 143 is disposed along the reciprocating direction of the driving member 14, the length of the second guide hole 143 is adapted to the reciprocating distance of the driving member 14, and the guide block 17 is disposed in the second guide hole 143 in a penetrating manner. Similarly, the number, shape, arrangement and arrangement position of the guide blocks 17 can be selected as required, and in this embodiment, the guide blocks 17 are preferably cylindrical, and a plurality of guide blocks 17 are uniformly distributed in the coverage area of the straight plate-shaped driving member 14, and the axial end portions of the guide blocks 17 can be fixedly connected (e.g., welded) to the bottom surface of the top supporting plate 12 or fixedly connected to the top surface of the bottom supporting plate 13.

Further, in the driving device for the modular belt roller of the present application, the driving mechanism 15 may be selected to have various suitable structures as required; as shown in fig. 1 and 3, in a preferred embodiment of the present application, the preferred drive mechanism 15 includes a cylinder 151 and a corresponding cylinder drive system (not shown in the figures); the cylinder 151 is disposed at the bottom of the bottom support plate 13, and has one end (left end in fig. 1) connected to the bottom support plate 13 and the other end (right end in fig. 1) connected to the driving member 14 to drive the driving member 14 to reciprocate.

Further, it is preferable that one end of the cylinder 151 is connected to the bottom support plate 13 through a second fixing block 154 and a second connecting member 155, and the other end of the cylinder 151 is connected to the driving member 14 through a first fixing block 152 and a first connecting member 153.

Specifically, the top end of the first fixing block 152 is fixedly connected to the driving member 14 through, for example, a bolt, and two lugs are arranged at the bottom end of the first fixing block 152; one end of the first connecting member 153 is provided with a single lug which is hinged in both lugs of the first fixing block 152 by a pin shaft, and the other end of the first connecting member 153 is fixedly connected to the end of the piston rod of the cylinder 151 by, for example, a bolt.

Further, in the driving apparatus for a modular belt drum of the present application, the arrangement of the steering roller 112 on the roller module 11 may adopt a variety of known suitable structures; in this embodiment, as shown in fig. 4, a roller mounting cylinder 115 is preferably fixedly disposed on the top of the base 111 of the roller module 11; the steering roller 112 is rotatably disposed in the roller mounting cylinder 115 through a pin, 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 be in contact with the roller on the belt.

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, and when the steering roller 112 rotates to the axis perpendicular to the axis of the roller 211, it acts as a brake, so that the roller 211 is always stationary; when the turning roller 112 rotates to an angle smaller than 90 degrees between the axis of the roller 211 and the axis of the roller 211, the roller 211 on the belt rubs against the turning roller 112 due to the movement of the belt, so that the roller 211 rotates.

Further, in another preferred embodiment of the present application, to reduce unnecessary (i.e., when the diversion is not needed) frictional contact of the steering roller 112 with the drum 211, the roller module 11 may be provided in a liftable configuration.

Specifically, as shown in fig. 5 and 6, the driving device for the modular belt pulley of the present application may further include a shoe 18; the mounting 18 is cylindrical and is fixedly arranged (e.g. nested) in the bearing hole 121, so that a roller module 11 is rotatably arranged in the inner cavity of the mounting 18 through the base 111 thereof; the diameters of the roller mounting cylinder 115 and the collet 18 are equal, the roller mounting cylinder and the collet are in contact through axial end faces, and contact faces between the roller mounting cylinder and the collet are all configured into regular and matched wavy teeth; it will be appreciated that the undulating tooth-end configuration causes the roller mounting cylinder 115 to be raised or lowered as the angle of rotation changes during rotation, thereby simultaneously effecting both the deflection of the deflection roller 112 and the contact or separation with the roller 211.

Further, in order to enhance the stability of the roller module 11 with the lifting function, a limiting plate 19 may be further included; the limiting plate 19 is vertically and fixedly arranged (for example, welded) on the top surface of the top supporting plate 12, wherein the vertical height of the limiting plate 19 is smaller than the distance between the top surface of the top supporting plate 12 and the supporting frame of the modular belt 21; in addition, at least one roller module 11 is arranged between two adjacent limiting plates 19, and arc-shaped grooves matched with the roller mounting cylinder 115 in shape are formed on the opposite side surfaces of the two limiting plates 19, so that the roller module 11 is radially limited from the opposite two sides through the arc-shaped grooves of the two limiting plates 19.

It should be noted that, the number and the arrangement position of the limiting plates 19 can be selected as needed, for example, when the number of the roller modules 11 is multiple and the roller modules are arranged in a row along the length direction of the limiting plates 19, two limiting plates 19 can be shared by two sides of the same row of roller modules 11, and one limiting plate 19 can be shared between two adjacent rows of roller modules 11.

Further, the driving device 22 may preferably adopt any one of the driving devices described in the first aspect, wherein at least one roller module 11 is disposed at the bottom of each roller 211 for driving, and specific numbers are not described herein again by way of example.

In addition, as shown in fig. 5 and 6, in another embodiment of the first aspect, namely, in an embodiment in which the roller module 11 adopts a structure that the mounting plate 18 with the wave-shaped teeth is matched with the roller mounting cylinder 115:

when the roller mounting drum 115 is rotated to have its undulating teeth misaligned with those of the shoe 18, the roller module 11 can be raised axially so that the diverting roller 112 contacts the roller 211 of the modular belt 21.

When the roller mounting drum 115 is rotated to a point where its undulating teeth fully engage the undulating teeth of the shoe 18, the roller module 11 can be axially lowered so that the diverting roller 112 disengages from the roller 211 of the modular belt 21. Of course, the specific height of the roller module 11 can be adjusted by adjusting the height of the wavy teeth.

It should be noted that, in the present embodiment, it is further preferable that the diameter of the turning roller 112 in the roller module 11 is larger than or equal to the diameter of the roller 211 in the modular belt 21.

Similarly, in the conveyor system of the present application, the driving member 14 drives the balance wheel transmission column 114 to rotate around the positioning column 113, so as to drive the roller module 11 to rotate, thereby realizing the driving of the rollers on the modular belt.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
