The left and right ends of the film roll are respectively provided with rotating shafts, and the rotating shafts at the left and right ends are respectively rotated and cooperated with the rotating grooves at the left and right ends. The film roll can be used to continuously provide film to the laminating machine body.

The detection device cooperates with the detection points to detect whether the film roll is rotating. The detection device is electrically connected to the main body of the laminating machine. When there is film on the film roll, the film roll rotates continuously under the drive of the film. Therefore, the detection device will continuously cooperate with different detection points. At this time, the detection device determines that there is film on the film roll and transmits a signal to the main body of the laminating machine, and the laminating machine can work normally. When the film on the film roll is used up, the film roll stops rotating because it is no longer driven by the film. Therefore, the detection device can no longer cooperate with different detection points. At this time, the detection device determines that the film on the film roll is used up and transmits a signal to the main body of the laminating machine, and the main body of the laminating machine stops working. From this analysis, it can be seen that this utility model can determine whether the film on the film roll is used up by cooperating with the detection device and the detection points, so as to stop the work of the main body of the laminating machine in time when the film on the film roll is used up.

The left and right ends of the film roll 2 are respectively provided with rotating shafts 3, and the rotating shafts 3 at the left and right ends are respectively rotatably engaged with the rotating grooves 102 at the left and right ends. The film roll 2 can be used to continuously supply film to the laminating machine body 1. The rotating groove 102 is provided with a detection device 4, and the rotating shaft 3 is provided with a plurality of detection points 5. The plurality of detection points 5 are distributed sequentially around the circumference of the rotating shaft 3. The detection device 4 cooperates with the detection points 5 to detect whether the film roll 2 is rotating. The detection device 4 is electrically connected to the laminating machine body 1. Function: (1) By setting up the main body of the laminating machine and the film roll, the main body of the laminating machine is provided with an assembly groove, and the left and right ends of the assembly groove are respectively provided with rotating grooves. The left and right ends of the film roll are respectively provided with rotating shafts. The rotating shafts at the left and right ends are respectively rotated and cooperated with the rotating grooves at the left and right ends. The film roll can be used to continuously provide film to the main body of the laminating machine. Thus, under the tension of the film applied by the main body of the laminating machine, the film roll will continuously rotate under the drive of the film. The film on the film roll continuously enters the interior of the main body of the laminating machine. The interior of the main body of the laminating machine heats and presses the film, so that the softened film is tightly bonded to the product, forming a laminated product and outputting it outward. (2) A detection device is provided by setting a rotating groove. The rotating shaft has several detection points, which are distributed sequentially around the circumference of the rotating shaft. The detection device cooperates with the detection points to detect whether the film roll is rotating. The detection device is electrically connected to the main body of the laminating machine. When there is film on the film roll, the film roll rotates continuously under the drive of the film. Therefore, the detection device will continuously cooperate with different detection points. At this time, the detection device determines that there is film on the film roll and transmits a signal to the main body of the laminating machine, and the laminating machine can work normally. When the film on the film roll is used up, the film roll stops rotating because it is no longer driven by the film. Therefore, the detection device can no longer cooperate with different detection points. At this time, the detection device determines that the film on the film roll is used up and transmits a signal to the main body of the laminating machine, and the main body of the laminating machine stops working. From this analysis, it can be seen that this utility model can determine whether the film on the film roll is used up by cooperating with the detection device and the detection points, so as to stop the work of the main body of the laminating machine in time when the film on the film roll is used up.
