In the embodiment of the present application, as shown in fig. 4, the third synchronizing wheel 303 is located between the first synchronizing wheel 301 and the second synchronizing wheel 302, the synchronous belt 30 is sequentially wound around the first synchronizing wheel 301, the third synchronizing wheel 303 and the second synchronizing wheel 302, and the synchronous belt 30 can be meshed with the first synchronizing wheel 301, the second synchronizing wheel 302 and the third synchronizing wheel 303. The synchronous belt 30 is meshed with the synchronous wheel to transmit motion and power, the synchronous belt 30 and the synchronous wheel do not slide relatively, linear speeds of the first synchronous wheel 301, the second synchronous wheel 302 and the third synchronous wheel 303 during rotation can be synchronous, accurate transmission ratio is achieved, and stability of the conveying device 100 is improved. Further, a third roller 403 is disposed between the first roller 401 and the second roller 402, a conveying belt 40 is wound around the first roller 401, the third roller 403, and the second roller 402 in this order, and the conveying belt 40 is frictionally coupled with the first roller 401, the second roller 402, and the third roller 403. The synchronous belt 30 is used for driving the third synchronous wheel 303 to rotate, so as to drive the central shaft 20 and the third roller 403 to rotate, and further drive the transmission belt 40 to move, thereby realizing the transportation of the materials on the transmission belt 40. The driving mechanism 50 is connected to the timing belt 30, and the driving mechanism 50 drives the timing belt 30 to move horizontally.

Further, as shown in fig. 7, the transportation device 100 may further include two third rollers 403, and the two third rollers 403 are symmetrically disposed on both sides of the third synchronizing wheel 303 along the axial direction of the central shaft 20.

Alternatively, the transport device 100 may include two parallel conveyor belts 40, and the two conveyor belts 40 are respectively wound around the two third rollers 403. The two third rollers 403 are arranged, so that the transmission width or the number of the transmission belts 40 can be correspondingly increased, the transmission belts 40 can transmit more materials, and the transmission efficiency of the transmission device 100 is improved.

In the transportation device 100 provided in the embodiment of the present application, the driving mechanism 50 is fixedly connected to the synchronous belt 30, and the driving mechanism 50 can move along the horizontal direction, so as to drive the synchronous belt 30 fixedly connected to the driving mechanism to move along the same direction. First synchronizing wheel 301 and second synchronizing wheel 302 pivot dress in support 10 both sides, and hold-in range 30 is around locating first synchronizing wheel 301, third synchronizing wheel 303 and second synchronizing wheel 302 in proper order for hold-in range 30 can drive the third synchronizing wheel 303 rather than the meshing in the removal in-process and rotate, and first synchronizing wheel 301 and second synchronizing wheel 302 enable hold-in range 30 and be in the tensioning state, reduce the probability that hold-in range 30 takes place to jump the area phenomenon, make the removal that the synchronization can be high-efficient stable. Since the third synchronizing wheel 303 and the third roller 403 are both fixedly connected to the central shaft 20, the third synchronizing wheel 303 can drive the central shaft 20 to rotate in the same direction when rotating, so that the third roller 403 and the third synchronizing wheel 303 rotate synchronously. Since the transfer belt 40 is wound around the first roller 401, the third roller 403, and the second roller 402 in this order. Therefore, the third roller 403 can rotate to drive the conveyor belt 40 to move in the horizontal direction, so as to transport the material on the conveyor belt 40.

In addition, since the first roller 401 and the second roller 402 are pivotally installed at both sides of the bracket 10, and the third roller 403 is located between the first roller 401 and the second roller 402. Therefore, the first roller 401 and the second roller 402 can tension the conveyor belt 40, thereby reducing the probability of the conveyor belt 40 slipping and enabling the conveyor belt 40 to move efficiently and stably. In this embodiment, the driving mechanism 50 drives the synchronous belt 30 to move, so as to drive the third synchronous wheel 303 to rotate, further drive the third roller 403 to synchronously rotate, and finally realize that the transmission belt 40 moves along the horizontal direction.

And when the transportation device 100 breaks down, the belt transmission mechanism is easy to maintain and replace, only damaged parts or parts with larger wear rate can be replaced, and the whole belt transmission mechanism does not need to be replaced. For example, when the driving mechanism 50 is damaged, only the driving mechanism 50 may be replaced, and the replacement difficulty is low. In addition, drive the transmission band 40 through hold-in range 30 and remove, stability is higher and not fragile, improves the holistic life of conveyer 100.

In some embodiments, as shown in fig. 7, the diameter of third roller 403 is greater than the diameter of third synchronizing wheel 303.

In the present embodiment, the third roller 403, the central shaft 20 and the third synchronizing wheel 303 are coaxially connected, so that the angular velocities of the rotation of the third roller 403, the central shaft 20 and the third synchronizing wheel 303 are the same. When the diameter of the third roller 403 is greater than that of the third timing wheel 303 and the third timing wheel 303 rotates at the same angle as the third roller 403, the distance that the conveyor belt 40 moves is greater than that of the timing belt 30. That is, when the driving mechanism 50 drives the synchronous belt 30 to generate a small displacement, the moving distance of the transmission belt 40 is far greater than that of the synchronous belt 30 within the same time, so that the stroke of the transmission belt 40 is enlarged, thereby improving the transportation efficiency of the transportation device 100, or reducing the energy consumption under the condition of ensuring the transportation efficiency.

In some embodiments, the diameter of the third roller 403 is 2 to 5 times the diameter of the third synchronizing wheel 303.

In the embodiment of the present application, the diameter of the third roller 403 may be 2 times to 5 times the diameter of the third synchronizing wheel 303, and may be set according to actual requirements, which is not limited in the present application. For example, the diameter of the third roller 403 may be 2.5 times, 3 times, or 3.5 times the diameter of the third synchronizing wheel 303. When the diameter of the third roller 403 is 2 to 5 times the diameter of the third synchronizing wheel 303, the moving distance of the transmission belt 40 is 2 to 5 times the moving distance of the synchronizing belt 30 in the same time. The moving distance of the conveying belt 40 is much greater than that of the synchronous belt 30, so that the stroke of the conveying belt 40 is enlarged, thereby improving the transportation efficiency of the transportation device 100 or reducing the energy consumption while ensuring the transportation efficiency.

The connection between the transportation device 100 and the external driving mechanism includes a snap connection or a sliding connection, which is not limited in this application. In addition, the first pressure plate 5021 and the second pressure plate 5022 may be connected in a variety of ways, specifically, the first pressure plate 5021 and the second pressure plate 5022 may be directly connected by welding, bonding, or the like, and the first pressure plate 5021 and the second pressure plate 5022 may be locked and connected by an intervening member such as a bolt or a screw, which is not limited in the present application.
