Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0025] Please refer to Figure 1 The transmission device 100 provided by the embodiments of the present application will now be described. The transmission device 100 comprises a driving shaft 10, a driven shaft 20, a non-powered shaft 30 and a conveyor belt 40.

[0026] Specifically, the driving shaft 10, the driven shaft 20 and the non-powered shaft 30 are arranged parallel to each other, the diameter of the driving shaft 10 is greater than the diameter of the driven shaft 20, the non-powered shaft 30 is arranged side by side with the driving shaft 10, the conveyor belt 40 is arranged around the driving shaft 10 and the driven shaft 20 at the same time, and the top of the non-powered shaft 30 is in contact with the bottom end of the conveyor belt 40.

[0027] It can be understood that the driving shaft 10 can drive the conveyor belt 40 to rotate when the driving shaft 10 rotates, and the conveyor belt 40 drives the driven shaft 20 to rotate. Since the diameter of the driving shaft 10 is greater than the diameter of the driven shaft 20, the transmission device 100 is provided with a smaller radius of curvature at one end of the driven shaft 20, which can reduce the gap and reduce the risk of clamping when the transmission device 100 is connected with other devices.

[0028] It is worth supplementing that the other device can be a feeding machine, a transport vehicle, a crane and the like, or another transmission device 100 provided in the embodiment of the application.

[0029] In addition, since the non-powered shaft 30 is arranged side by side with the driving shaft 10, and the top of the non-powered shaft 30 abuts against the bottom end of the conveyor belt 40, the conveyor belt 40 can also drive the non-powered shaft 30 to rotate. After the non-powered shaft 30 abuts against the bottom end of the conveyor belt 40, the transmission device 100 is provided with a reduced up-down spacing of the conveyor belt 40 at one end of the driven shaft 20, so that the transmission device 100 is more light and thin, and the volume is reduced.

[0030] In another embodiment of the application, please refer to Figure 1 , the top of the driving shaft 10 is at the same horizontal height as the top of the driven shaft 20, and the bottom of the driven shaft 20 is at the same horizontal height as the top of the non-powered shaft 30.

[0031] In this way, the upper half and the lower half of the conveyor belt 40 are parallel to each other and opposite in direction, which improves the transmission stability.

[0032] Preferably, please refer to Figure 1 , the diameter of the driving shaft 10 is equal to the sum of the diameter of the driven shaft 20 and the diameter of the non-powered shaft 30.

[0033] Preferably, please refer to Figure 1 , the driving shaft 10 is an electric drum.

[0034] It can be understood that the electric drum is a new type of driving device in which the motor and the speed reducer are arranged in the drum body, which can further reduce the overall volume.

[0035] Preferably, please refer to Figures 2-3 , the driven shaft 20 is provided with a plurality of bushings 21.

[0036] It can be understood that the bushing 31 can reduce friction and improve the transmission stability of the conveyor belt 40.

[0037] In another embodiment of the application, please refer to Figures 2-3, the transmission device 100 comprises a pair of rotating assemblies 50, the rotating assembly 50 comprises a side plate 51, a belt bearing 52 and a tumbling shaft 53, the two ends of the driving shaft 10, the driven shaft 20 and the non-powered shaft 30 are movably arranged between a pair of the side plates 51, one end of the tumbling shaft 53 is fixedly connected with the corresponding side plate 51, and the other end is arranged in the belt bearing 52.

[0038] It can be understood that when a pair of side plates 51 are connected with the belt bearing 52 through the tumbling shaft 53, the transmission device 100 can be turned over, which is beneficial to maintenance.

[0039] Please refer to Figure 4 The application also provides a sealing device 200, which comprises a sealing mechanism 210 and a pair of transmission devices 100 as described above, the pair of transmission devices 100 are symmetrically arranged and located inside the sealing device 200, and the sealing mechanism 210 is located between the non-powered shafts 30 of the pair of transmission devices 100.

[0040] In this way, during the sealing of the articles by the sealing mechanism 210, the articles can be transmitted to the sealing mechanism 210, and the sealing belt of the sealing mechanism 210 can seal the articles through the gap between the pair of transmission devices 100. Since the end of the driven shaft 20 of the transmission device 100 has a smaller radius of curvature, the flatness of the connection is improved, so that the probability of article jamming is reduced, and the stability of article transmission is improved.

[0041] In another embodiment of the application, the transmission device 100 comprises a rotating power unit (not shown in the figure), which is connected with the tumbling shaft 53.

[0042] It can be understood that on the one hand, the rotating power unit can directly drive the transmission device 100 to turn over, which is convenient for maintenance and reduces manual work. On the other hand, when the articles are located on the transmission device 100, the turnover function can be used to turn over the articles to adjust the posture of the articles and improve the sealing quality of the articles.

[0043] The above description is only the preferred embodiment of the application and is not used to limit the application, any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
