Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings. Figure 1-2 The invention shows a transmission structure of a film conveying platform, comprising: a film guide frame 1, a constant velocity universal joint 2, a connecting shaft 3, a main pulley 4, a slave pulley 5 and a power assembly. The film guide frame 1 comprises a platform 101 and a side guard plate 102. Side guard plates 102 are arranged on both sides of the platform 101. The side guard plates 102 of two adjacent film guide frames 1 are connected by a connecting shaft 3. The connecting shaft 3 is perpendicular to the side guard plates 102. A slave pulley 5 is arranged on the connecting shaft 3. One end of the side guard plate 102 extends out of one end of the platform. At the extended end, The side guard plates 102 are coaxially penetrated with a connecting shaft 3 and a constant velocity universal joint 2. The side guard plates 102 between each two adjacent film guide frames 1 are connected with a constant velocity universal joint 2. The side guard plates 102 between each film guide frame 1 are connected with a connecting shaft 3. The connecting shaft is provided with a main pulley 4. A belt is penetrated between the main pulley 4 and the corresponding slave pulley 5 located in the same row. The connecting shaft 3 and the constant velocity universal joint 2 are alternately connected. A power assembly is provided on the outermost film guide frame 1, and the constant velocity universal joint 2 near the position is connected to the power assembly. Here, the constant velocity universal joint 2 is used to replace the previous hexagonal shaft, so that the transmission efficiency is not only high but also stable during the film feeding process, and the gap impact at the connection of each film guide frame 2 is reduced, and the concentricity between them does not need to be guaranteed. The stability of the entire film guide frame conveying is improved, and it is easy to disassemble and install, which increases the service life of the film guide conveyor. Therefore, this new transmission structure improves the reliability of film feeding during the film feeding process.

[0018] Among them, the power component includes a motor, a main sprocket 6, a slave sprocket 7 and a connecting shaft 3. The main sprocket 6 is provided on the output shaft of the motor, and the slave sprocket 7 is provided on the connecting shaft 3. The main sprocket 6 and the slave sprocket 7 are connected by a chain. The connecting shaft 3 is connected to the constant velocity universal joint 2 near the location. The motor and the connecting shaft 3 are installed on a bracket 8, and the bracket 8 is fixed on the side guard plate 102 of the outermost film guide frame 1.

The number of slave pulleys 5 corresponding to the main pulley 4 and located in the same column is not less than 5. Since the film guide frame is long, more slave pulleys are set to give the belt on it a more stable conveying force.

[0020] The working principle of this utility model:

[0021] Turn on the motor, and the slave sprocket 7 on its output shaft rotates, driving the main sprocket 6 to rotate, and then driving the alternately connected connecting shafts and constant velocity universal joints to rotate accordingly, and then the main pulley 4 on each connecting shaft rotates, and finally drives the slave pulley 5 located in the same column as the main pulley 4 to rotate, and then the belt starts to convey.
