[0022] The unwinding roller and the first driven wheel in the conveying device are connected by an O-belt, and the friction transmission characteristics of the O-belt can effectively avoid the risk of pinching the hand between the unwinding roller and the rocker pressure wheel of the external sealing mechanism, thereby effectively reducing the production safety risk;

[0023] Moreover, the first O-shaped groove and the second O-shaped groove for cooperating with the O-shaped belt can be integrally formed on the first driven wheel and the second driven wheel, thereby saving the cost of the sprocket compared to the sprocket chain transmission, thereby meeting the economic benefits and satisfying the production needs.

[0024] Furthermore, a plurality of U-shaped grooves 12 are provided at intervals on one side of the connecting frame 1, and a plurality of first screw holes are provided on one side of the seat body 7 corresponding to the plurality of U-shaped grooves 12. Connecting screws (not shown in the figure) that can be threadedly connected with the first screw holes are inserted into the U-shaped grooves 12. Specifically, the relative installation position between the seat body and the connecting frame can be effectively adjusted by cooperating with the connecting screws, the U-shaped grooves and the first screw holes, so that the tension of the O-belt can be effectively adjusted by adjusting the position of the seat body.

[0025] Furthermore, a second screw hole 13 is provided at intervals through one side of the connecting frame 1, and a tightening screw (not shown) that can tighten one side of the seat body 7 is inserted into the internal thread of the second screw hole 13.
