The first sensor 640 and the second sensor 650 are respectively disposed on the rack 100, when the swinging member 630 swings to a first angle, the sensing portion 632 senses with the first sensor 640, and when the swinging member 630 swings to a second angle, the sensing portion 632 senses with the second sensor 650. The first sensor 640 and the second sensor 650 are respectively in signal connection with the film releasing mechanism 200, and when the sensing part 632 senses that the material belt is too loose with the first sensor 640, the film releasing mechanism 200 needs to slow down the unwinding speed; when the sensing portion 632 senses with the second sensor 650, it indicates that the material belt is too tight, and the film releasing mechanism 200 needs the block releasing speed.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
