The first film material conveying assembly 1-1 includes a first film roll drum 1-1-2 and a first film unwinding driving device 1-1-1. Among them, the incoming film fixing roller 1-4-1 and the outgoing film fixing roller are installed on the frame, and the movable roller 1-4-2 is slidably connected to the frame up and down. Preferably, a plurality of movable rollers 1-4-2 and intermediate fixing rollers that are parallel to each other and arranged alternately are provided between the incoming film fixing roller 1-4-1 and the outgoing film fixing roller. The film roll is placed on the first film roll drum 1-1-2, and the extending end of the film roll sequentially passes through the incoming film fixing roller 1-4-1, the movable roller 1-4-2, and the outgoing film fixing roller. Among them, the intermediate fixing rollers are respectively arranged before and after the movable roller 1-4-2 and are used to support the film material introduced and led out by the movable roller 1-4-2. The incoming film fixing roller 1-4-1, the movable roller 1-4-2, the intermediate fixing roller, and the outgoing film fixing roller constitute a film material caching device 1-4. When the film material on the first film roll drum 1-1-2 is sufficient, the movable roller 1-4-2 is at the lowest end of its connection with the frame.

During this caching period, a new film roll can be replaced in time. Therefore, the operation of loading the film can be achieved without stopping the machine, and the production efficiency can be improved. After the film material is released, the weak soldering device 3 can perform weak soldering on the released film material on the film roll, and then the bag making device 7 performs solid soldering on the film material and cuts out multi-chamber flexible bags 3-6 on the film material.

In addition, the film material conveying device also includes a film material docking platform 1-2, and the film material drawn out from the film roll first passes through the film material docking platform 1-2, and then passes through the film input fixed roller 1-4-1. When one roll of film material is used up, the film material can be docked through the film material docking platform 1-2 to ensure the continuity of the film.
